Pharmacists Don’t Want to Sell Unproven Products

Pharmacists Don’t Want to Sell Unproven Products

The Pharmaceutical Society doesn’t think pharmacists should be able to sell healthcare products with no evidence of efficacy.

Last week I wrote about the Pharmacy Council’s proposal to change their Code of Ethics, and summarised the submissions that I was aware of. One important organisation that was missing from that roundup is the Pharmaceutical Society.

The Pharmaceutical Society is a professional association representing New Zealand pharmacists. Given their important position in the pharmacy industry, I think their submission might arguably be the most important. Earlier this week I spoke with Bob Buckham, Chief Pharmacist Advisor at the Pharmaceutical Society, about their submission on the Pharmacy Council’s proposal.

The Pharmaceutical Society does not support the proposed change. Coming from the perspective of pharmacists, their submission also raised two important points around this issue:

  • Pharmacists need clarity: what behaviour is consistent with the Code of Ethics, and what is not?
  • The Code of Ethics is important and cannot be ignored. The Pharmacy Council must be willing to provide guidance and to enforce the code.

The reason why the Pharmaceutical Society does not support this change is similar to the reasons given by other organisations, in that it would implement a double standard:

The Society does not support the proposed supplementary wording in obligation 6.9 as the split wording in the two parts separates the therapy terms “medicine or herbal remedy” in 6.9a from “complementary therapy or other healthcare product” in 6.9b. The result is that the subsequent obligation attached to those therapies does not apply to the other.

To clarify further, “credible evidence of efficacy” is only required when supplying or promoting a “medicine or herbal remedy” (Obligation 6.9a) and “no reason to doubt… quality or safety and when sufficient information about the product can be provided” only applies to “any complementary therapy or other healthcare product.

The Society considers that the obligations of “credible evidence of efficacy” and no reason “to doubt… quality or safety” should apply to the supply or promotion of all therapies and products – ie. any medicine, herbal remedy AND any complementary therapy or other healthcare product.

Submission to the Pharmacy Council of New Zealand (Pharmaceutical Society of New Zealand)

Like other submissions, the Pharmaceutical Society does support the addition of a new clause about providing sufficient information for patients to make informed choices. However, they also made a similar suggestion to one in the Society for Science Based Healthcare’s submission in that the wording of this clause should be strengthened:

The Society also considers that “sufficient information about the product” must be provided in order for purchasers to make an informed choice with respect to efficacy of that product and the risks and benefits of that against other treatment options.

Submission to the Pharmacy Council of New Zealand (Pharmaceutical Society of New Zealand)

Aside from their comments on the new proposed wording, the Pharmaceutical Society raised concerns about the application of this section of the Code of Ethics. Part of their submission focussed on pharmacists’ responsibility to comply with the Code of Ethics:

Pharmacists must comply with the Code of Ethics
The Council have stated that it is not the purpose of the Code, or the Council, to endorse or prohibit the supply of any particularly complementary and/or alternative medicine, product, or practice. However, as the responsible authority for pharmacy under the Health Practitioners Competence Assurance Act 2003, standards of ethical conduct set by the Council must be observed by pharmacists. Indeed, in the Code of Ethics the Council requires that pharmacists must comply with “all the implied requirements of ethical practice” within the Code.

The Medicines Regulations 1984 (in Schedule 2 related to applications for a licence to operate a pharmacy) also refers to how pharmacists being employed or engaged in duties in a pharmacy are

not requested or required to act in a way that is inconsistent with the applicable professional or ethical standards of the pharmacy practice

Therefore, the obligations within the Code of Ethics must be interpreted clearly so that pharmacists have a clear understanding of what is considered ethical practice, but also so that the Council can investigate and act upon breaches of the Code.

Submission to the Pharmacy Council of New Zealand (Pharmaceutical Society of New Zealand)

This call for clarity has been a common theme among submissions. Both the NZ Skeptics’ submission and Dr Ben Albert’s submission called for guidelines on product categories that should not be sold in pharmacies due to a lack of evidence. Also, when the Society for Science Based Healthcare complained to the Pharmacy Council last year, one of the recommendations made was to for the Pharmacy Council provide guidance on this issue:

As a result of this complaint, we want pharmacists to have the opportunity to do the right thing and fulfill their ethical obligations. In order to achieve this, we suggest that the Pharmacy Council consider the following courses of action:

  1. To assist pharmacies in evaluating whether or not a healthcare product is supported by credible evidence of efficacy, the Pharmacy Council should develop and publish guidelines regarding what constitutes credible evidence of efficacy. This need not be a strict requirement so much as a useful guide that pharmacists can use to establish a consistent minimum standard of evidence.

NaturoPharm Wartoff Complaint (Society for Science Based Healthcare)

If it’s unclear where the line is drawn with regard to “credible evidence of efficacy”, it makes it more difficult for pharmacists to practice ethically. The Pharmaceutical Society’s submission raises questions about where this line might be drawn regarding alternative healthcare products, and talks about how the Code will be applied in practice:

Definition and interpretation of obligations
The wording of the proposed obligations 6.9a and 6.9b make reference to “credible evidence of efficacy” and “quality and safety”. Therefore, if presented with a complaint against a pharmacist claimed to be in breach of the obligations within the Code of Ethics, the Council is expected to determine what is “credible evidence of efficacy” and/or “quality or safety”.

The Society recognises that the application of a principles-based Code of Ethics to individual scenarios or circumstances is open to interpretation and challenge. Such scenarios are often not “black and white”, but “shades of grey” where a group of peers may have differing opinions to the acceptability or otherwise of a particular practice. It is expected that such “shades of grey” will always exist in pharmacy practice, as indeed it does in medicine and other areas of professional practice. However where a particular practice is determined to be unethical or unacceptably, this must be made clear. This is a difficulty faced when considering the evidence and use of complementary treatments against regulated medicines.

Submission to the Pharmacy Council of New Zealand (Pharmaceutical Society of New Zealand)

The submission goes on to compare “natural” or herbal healthcare products with homeopathic products, in terms of plausibility:

Complementary/alternative medicine: natural/herbal remedies
The Society recognises the history of pharmaceuticals, and indeed of the pharmacy profession, where the first “medicines” were derived from natural products. Many of these have been purified, refined and further manipulated in the development of modern day pharmaceutics. Much of modern pharmaceutical research continues to analyse the therapeutic potential of compounds found naturally occurring substances derived from flora and fauna. We recognise how the levels of evidence of the therapeutic benefits (or otherwise) of natural products can vary markedly, but understand the science behind their potential mechanisms of action has the same pharmacological basis and pharmaceuticals.

Homeopathy
We note the Council’s own ‘Complementary and alternative medicines – best practice guidance for pharmacists’ document makes reference to the Natural Health and Supplementary Products Bill which states:

currently there is no accepted scientific evidence for the effectiveness of homeopathy and therefore that health benefit claims should not be made for homeopathic products

This aligns with further documents and statements issued internationally, including the Australian National Health and Medical Research Council (NHMRC)(1), the Cochrane Library and others have noted homeopathic products show no effects beyond placebo. A large number of government committees, professional pharmacy and medical organisations internationally have issued statements reinforcing this lack of effectiveness of homeopathy in treating health conditions. The Pharmaceutical Society of New Zealand does not at this time have a position statement on complementary medicines or homeopathy.

Homeopathy is not herbalism, and homeopathic science is not consistent with currently accepted medical and pharmacological science. Some pharmacists, and indeed other health professions, have argued for the role of homeopathy as a valid form of treatment to meed patient demand, while acknowledging any “benefit” is achieved through a placebo effect, while not necessarily agreeing with the purported science behind homeopathic practice.

The question for the Council must then be whether it is considered ethical practice for pharmacists to charge a fee for products for which there is no accepted scientific evidence for effectiveness; OR for which they acknowledge a lack of evidence yet sell for the purposes of providing a placebo effect.

Canberra: National Health and Medical Research Council; 2015. Available from: https://www.nhmrc.gov.au/guidelines-publications/cam02

Submission to the Pharmacy Council of New Zealand (Pharmaceutical Society of New Zealand)

The Pharmaceutical Society also noted something that was raised in a few other submissions; when pharmacies sell ineffective products they lend them the credibility of their profession, which can inadvertently lead to patients being misled about their efficacy.

While we again note that the Council have expressed that it’s not their purpose or the purpose of the Code of Ethics to “endorse any particular complementary or alternative medicine or practice”, in setting the requirements for pharmacists to conform with obligation 6.9 (or 6.9a and 6.9b), the Council must determine whether the practice of homeopathy is consistent with the Code. Particularly when having homeopathic products available alongside pharmaceutical medicines, or indeed herbal/complementary medicines with their varied levels of evidence, potentially implies clinical benefit by association and provision through a respected and regulated health professional.

Submission to the Pharmacy Council of New Zealand (Pharmaceutical Society of New Zealand)

I’ve not yet been made aware of any other submissions that have been made to the Pharmacy Council, but I imagine a number of individuals at least will have made submissions that have not been publicised. As it stands though, the Pharmacy Council’s proposal seems to have strong opposition from all sides, with the only significant support I have seen so far coming from the Pharmacy Guild, who represent only those pharmacists who own their own pharmacies.

It seems no group other than pharmacy owners wants to keep the status quo of pharmacies selling ineffective products without consequences.

Pharmacy Council’s Code of Ethics Proposal: Submissions Roundup

Pharmacy Council’s Code of Ethics Proposal: Submissions Roundup

The Pharmacy Council has proposed a change to their code of ethics, here’s everything you need to know.

EDIT 22/10/2015: When this article was published it didn’t include details of the Pharmaceutical Society’s submission. Since then, I have spoken with their Chief Pharmacist Advisor, Bob Buckham, about their submission. For more details, see my article summarising it: Pharmacists Don’t Want to Sell Unproven Products

The Pharmacy Council is the statutory body responsible for setting standards of conduct and competence of pharmacists in New Zealand. They have a code of ethics, the Safe Effective Pharmacy Practice Code of Ethics 2011, which currently includes a section that requires pharmacists must:

6.9
Only purchase, supply or promote any medicine, complementary therapy, herbal remedy or other healthcare product where there is no reason to doubt its quality or safety and when there is credible evidence of efficacy.

Safe Effective Pharmacy Practice Code of Ethics 2011 (Pharmacy Council)

In August, the Pharmacy Council proposed to change this section of the code of ethics. The first part of the proposed change is to remove the requirement for complementary therapies and other healthcare products to be supported by credible evidence of efficacy before they can be promoted or supplied in a pharmacy. The other part is to add a requirement that purchasers must be given enough information about these products to make an informed choice:

6.9a
Only supply or promote any medicine or herbal remedy where there is no reason to doubt its quality or safety and when there is credible evidence of efficacy.
6.9b
Only supply any complementary therapy or other healthcare product where there is no reason to doubt its quality or safety and when sufficient information about the product can be provided in order for the purchaser to make an informed choice with regard to the risks and benefits of all the available treatment options.

Proposed supplementary wording to clause 6.9 of the Code of Ethics 2011 (Pharmacy Council)

As part of this proposal, the Pharmacy Council called for submissions from stakeholders. In my last article on this topic, I discussed the submission from the Society for Science Based Healthcare, of which I am a co-founder. Although the extended deadline for submissions passed last Friday, various other groups have made their views on this proposal clear and made their own submissions.


The Society for Science Based Healthcare

The Society for Science Based Healthcare is a group of consumer advocates, scientists, and medical professionals. I am one of its co-founders. The submission from the Society for Science Based Healthcare proposed a modified version of the new wording:

6.9a
Only supply any medicine or herbal remedy where there is credible evidence of efficacy.
6.9b
Only promote any complementary therapy or other healthcare product where there is credible evidence of efficacy.
6.9c
Only supply or promote any medicine, herbal remedy, complementary therapy or other healthcare product where there is no reason to doubt its quality or safety, when there is not credible evidence to suggest that the product lacks efficacy.
6.9d
Provide sufficient information about any medicine, herbal remedy, complementary therapy or other healthcare product product in order for the purchaser to make an informed choice with regard to the risks and benefits of all the available treatment options.

Pharmacy Council Code of Ethics Proposal (Society for Science Based Healthcare)

After lodging a complaint last year with the Pharmacy Council regarding an incident in which a patient was misled by an Auckland pharmacy that recommended and sold them a homeopathic product, both the Pharmacy Council and the Health and Disability Commissioner refused to enforce the code by telling the pharmacy not to promote or sell the homeopathic product, despite the fact that it was not supported by any credible evidence of efficacy.

In principle, the society would oppose the change. However, having have found that the existing section of the code is disregarded rather than enforced, the society decided it was best to try to turn the code into something the Pharmacy Council might be willing to enforce that could still offer protection to patients.

It is currently widespread practice for New Zealand pharmacies to supply and promote healthcare products which are not supported by credible evidence of efficacy, such as homeopathic products.

Pharmacy Council Code of Ethics Proposal (Society for Science Based Healthcare)

This view that the current code of ethics is commonly disregarded has been shared among many of the other submissions that have been made public, and appears to be supported by a statement made by the Pharmacy Council chairman Dr Andrew Bary in a recent article on Stuff.co.nz:

But Pharmacy Council chairman Dr Andrew Bary said the rules as they stood were “unworkable” and many pharmacists, including himself, were already selling complementary medicines, even if they didn’t believe their claims.

Doctors and pharmacists clash over complimentary medicines (Stuff.co.nz)

The Society for Science Based Healthcare’s submission also argued that there are both potential risks and potential benefits to these products being sold in pharmacies. The proposed new wording is intended to provide the best risk/benefit profile for patients.

On the one hand, if these products are available in a pharmacy consumers will be more likely to visit a pharmacy to purchase them. This can put them in a position where a pharmacist is able to provide them with evidence-based advice, so they can make an informed decision on purchasing the best product for whatever problem they are experiencing. If the product were not available in a pharmacy, they may instead seek it from a source which would not provide them with this information, or which may misinform them.

On the other hand, when a product is available in pharmacies it is likely to lead consumers to believe that it is an effective, evidence-based product. This is often used as a selling point by products which are not supported by evidence. For example, the homeopathic product No-Jet-Lag advertises itself as being available at “Most chemists nationwide“. In this way, pharmacists stocking products without credible evidence of efficacy can also contribute to an increase in consumer demand for them. For all intents and purposes, supplying a product in a pharmacy is also a form of promotion.

Pharmacy Council Code of Ethics Proposal (Society for Science Based Healthcare)

When it was submitted this submission had a list of 36 supporters, 24 of whom are healthcare professionals or PhD scientists


The NZ Skeptics

The NZ Skeptics’ submission opposed the change. It also proposed that the Pharmacy Council maintain a list of products or product categories that are not supported by credible evidence of efficacy, to make it easier for pharmacists to determine which products could or could not be sold in pharmacies. The motivation for this recommendation is similar to one made in the Society for Science Based Healthcare’s complaint last year:

As a result of this complaint, we want pharmacists to have the opportunity to do the right thing and fulfill their ethical obligations. In order to achieve this, we suggest that the Pharmacy Council consider the following courses of action:

  1. To assist pharmacies in evaluating whether or not a healthcare product is supported by credible evidence of efficacy, the Pharmacy Council should develop and publish guidelines regarding what constitutes credible evidence of efficacy. This need not be a strict requirement so much as a useful guide that pharmacists can use to establish a consistent minimum standard of evidence.

NaturoPharm Wartoff Complaint (Society for Science Based Healthcare)

To inform their submission, the NZ Skeptics conducted a “secret shopper” exercise with their members to discover what actually happens when consumers talked to pharmacy staff about homeopathy.

We found that around half of the pharmacies visited had staff that were willing to promote or supply homeopathic products without adequately explaining the current lack of evidence.

It seems that some pharmacies did not stock homeopathy, but a significant number of others did have homeopathic products on their shelves and in most of these pharmacies staff were willing to offer homeopathy as a viable treatment, with no information offered about a lack of efficacy.

With the code being an important patient protection mechanism, we’re disappointed to see it so readily disregarded.

Submission to the Pharmacy Council’s 2015 Code of Ethics Consultation (NZ Skeptics)

The NZ Skeptics have made these reports available on their website: Pharmacy Homeopathy Reports. As well as this, they conducted a non-exhaustive search for New Zealand pharmacies promoting homeopathic products online, and made the results of this available too: Pharmacies Promoting Homeopathy.

One argument that is used to support pharmacies selling products with no credible evidence of efficacy is that, if pharmacists were prevented from selling these products, then patients’ freedom of choice would be infringed. This argument has been made, for example, by Pharmacy Council chairman Dr Andrew Bary when he was interviewed on Radio New Zealand about this proposed change:

You know, I think we need to respect the wish of the consumer from time to time, so you know, individuals have their own cultural and traditional beliefs around certain alternative and complementary therapies… So I think that the key thing is that we are setting out that we think pharmacists should be informed about the efficacy of the evidence for each individual product when they are promoting and making recommendations to people. But at the same time, we need to put the person at the centre, the consumer, and respect their wishes and desires.

Pharmacy Council moves to change code of ethics over homeopathy (Radio New Zealand)

The argument has also been put forth by pharmacists that sell these products in their pharmacies:

“Many patients believe homeopathy has been of benefit and they should be given the freedom to choose it if they want, [Lincoln Mall Pharmacy owner pharmacist Caleb Townsend] says.”

Pharmacists support patient choice with homeopathy (Pharmacy Today)

It may be worth noting that Lincoln Mall Pharmacy is one of the ones on the NZ Skeptics’ list of pharmacies promoting homeopathy online, and the Pharmacy Today article notes they have “qualified homeopaths onsite”. An Advertising Standards Authority complaint laid by Society for Science Based Healthcare member Simon Clark was settled in June when the pharmacy opted to remove claims that homeopathic products can “treat a wide range of illnesses and concerns” from an online listing.


Ben Albert et al.

Dr Ben Albert is a paediatric endocrinologist who researched fish oil for his PhD, which made headlines earlier this year after his research was published in the Nature journal Scientific Reports. Along with five other doctors, he has written a submission to the Pharmacy Council opposing the change.

Despite coming from a group of individuals rather than a professional society, the submission boasts the impressive support of 180 medical doctors, predominantly senior consultants, representing all medical specialties. It also has the support of the NZ Society of Paediatric Surgeons and the NZ Resident Doctors Association, which represents over 90% of the resident medical officer workforce in New Zealand. Its authors are:

  1. Dr Benjamin B. Albert FRACP, Paediatric Endocrinologist and Clinical Research Fellow. Liggins Institute, University of Auckland.
  2. Professor Wayne S. Cutfield MD FRACP. Professor of Paediatric Endocrinology, and Director of A Better Start National Science Challenge, Liggins Institute, University of Auckland. Past president, Australasian Paediatric Endocrinology Group. Past president, Asia Pacific Paediatric Endocrine Society.
  3. Professor Paul L. Hofman FRACP. Professor of Paediatric Endocrinology, Director of the Maurice and Nessie Paykel Clinical Research Unit, Liggins Institute, University of Auckland. President Asia Pacific Endocrine Society. Past president Australasian Paediatric Endocrinology Group.
  4. Professor Alistair J. Gunn PhD FRACP. Professor of Physiology and Paediatrics, and Head of Department of Physiology, University of Auckland. Paediatric Endocrinologist.
  5. Associate Professor Timothy Kenealy PhD FRANZCGP, Professor of Integrated Care, University of Auckland. General Practitioner.
  6. Dr Olivia J. Albert FANZCA. Anaesthetist, Royal Hospital for Women, Sydney, Australia.

The specific recommendations made in their submission are:

  • Reject the proposed change, or reinsert the requirement for “credible evidence of efficacy” in to clause 6.9b. We suggest this wording.

    • where there is no credible evidence to suggest a specific complementary and/or alternative medicine/product is effective, or the proposed effect of the product is scientifically implausible pharmacists should not promote or recommend its use
  • Current ethical standards should be enforced
  • Treatments and products that do not have “credible evidence of efficacy” such as homeopathic remedies, ear candles and magnet based therapies should be listed by the PCNZ, with the intention that they are not sold in pharmacies.

Submission to the Pharmacy Council of New Zealand (Ben Albert et al.)

The last recommendation echoes that of the NZ Skeptics, aiming to simplify things for pharmacists by providing a list of products or product categories which clearly are not supported by credible evidence of efficacy.

The rationale for their opposition to the change is laid out clearly and concisely in the submission:

The suggested change is in opposition to the general principles of the code, and the expectations of the public and other members of the multidisciplinary science based healthcare team.

This change would make it permissible within the ethical code for pharmacists to promote and sell products that are unproven and even scientifically implausible. We believe that this is harmful and wrong.

the current code should be enforced, not amended.

Submission to the Pharmacy Council of New Zealand (Ben Albert et al.)

They raise another counterargument to the “freedom of choice” argument, noting that pharmacists should be wary of their conflict of interest between advising against patients purchasing products that aren’t supported by evidence and selling more products to generate more profit for the pharmacy:

pharmacists (like many health providers) have a conflict of interest when they sell and give advice about health products from which they make profit. There is evidence that financial pressures do impact the clinical decisions of pharmacists1. One of the reasons that a code of ethics is important is because it provides guidance where the interests of pharmacists and patients differ.

Submission to the Pharmacy Council of New Zealand (Ben Albert et al.)

They also raise the issue that products sold in pharmacies are likely to be seen as effective by the public, which can lead to harm when they are sold in pharmacies:

Many patients will assume that the pharmacist endorses the health products sold in the pharmacy as scientifically supported. But many pharmacists sell products that are known to be ineffective, such as homeopathic remedies3 or potentially harmful, such as ear candles4. Selling such products conflicts with the principles of the current code5 as it reduces patient autonomy. The patient that wrongly assumes that a health product is scientifically supported is ill-prepared to make an informed decision.

Submission to the Pharmacy Council of New Zealand (Ben Albert et al.)

Although this submission has not been made public, it shares much in common with a letter to the editor from the same authors that was published today in the New Zealand Medical Journal.

I spoke with Dr Albert to ask what motivated him to take action on the Pharmacy Council’s proposal, here’s what he had to say:

For years it has bothered and surprised me that products that are entirely implausible such as magnets and homeopathic remedies, and harmful products such as ear candles are sold in pharmacies. When scientifically trained and trusted health professionals promote and sell such treatments they betray the trust of the public who will quite reasonably assume such products are endorsed by the pharmacist and supported by scientific evidence. The current PCNZ code of ethics indicates that it is unethical and unprofessional for pharmacists to sell these products. The right course of action is to stop selling them. To instead change the code to redefine ethical behaviour appears cynical and makes the sale of unsupported or harmful treatments no less wrong.

Dr Ben Albert


The New Zealand Medical Association

The New Zealand Medical Association is New Zealand’s largest medical organisation, representing over 5,500 medical professionals. The New Zealand Medical Association’s submission strongly opposes the change. They echo the views of other submissions that in the face of widespread behaviour at odds with the current code, the way forward should be change behaviour to match the code rather than to relax the code to permit existing behaviour:

The NZMA is strongly opposed to the above proposed change

We do not believe that pharmacists should be selling ‘treatments’ that are known to be ineffective or lack evidence of effectiveness. We contend that doing so is unethical. While this practice may be happening under the present Code, we believe that the PCNZ should be seeking ways to enforce the Code rather than amend it to accommodate this practice.

Submission to the Pharmacy Council of New Zealand (New Zealand Medical Association)

The NZMA acknowledged the trust placed in pharmacists by the public, and how this affects the way in which products sold in pharmacies are perceived:

It is our view that allowing pharmacists to sell ineffective therapies or products is contrary to the profession’s own aspirations, including of trustworthiness and professionalism. More broadly, it undermines the social contract between the public and the profession. The pharmacist is trusted by patients and other members of the health care team precisely because of their scientific training. The sale of products by pharmacists that knowingly do not work is inconsistent with the high trust health care professional the public expects and the profession requests.

Submission to the Pharmacy Council of New Zealand (New Zealand Medical Association)

The NZMA also deals with the “freedom of choice” argument in a similar way to the other submissions:

We understand that patient autonomy and freedom of choice are being advanced as the rationale for the proposed rewording to the Code. We believe these are spurious arguments on which to remove the requirement for “credible evidence of efficacy” for pharmacists to sell complementary therapies or other healthcare products. Freedom of choice should not transcend the health and well-being of the patient. Furthermore, such products are already available to people to purchase at other outlets, such as health food shops and supermarkets.

Submission to the Pharmacy Council of New Zealand (New Zealand Medical Association)

The NZMA raised some new concerns, regarding the potential impacts of the proposed change:

The proposal is of all the more concern given the current lack of regulation of complementary therapies in New Zealand.

We are also concerned at the impact of the proposal on equity. Patients that are least likely to consult a doctor could end up being even more likely to purchase costly ‘healthcare’ products from their pharmacy that do not work.

The proposal also undermines the wider health sector’s efforts to improve health literacy.

Submission to the Pharmacy Council of New Zealand (New Zealand Medical Association)

The NZMA’s final recommendation is for the requirement for credible evidence of efficacy to be kept and enforced, and until it is enforced for the newly proposed requirement for supplying sufficient information to make an informed choice to bridge the gap:

Ideally, we would like to see pharmacists end the sale of complementary therapies or other healthcare products for which there is no credible evidence of efficacy (ie, meet their obligations under the existing Code). Until such time, we would suggest the addition of a subclause to 6.9 which addresses the need to provide sufficient information for herbal remedy, complementary therapy or other healthcare product. Accordingly, we proposed the following wording:

6.9
Only purchase, supply or promote any medicine, complementary therapy, herbal remedy or other healthcare product where there is no reason to doubt its quality or safety and when there is credible evidence of efficacy.
6.9a
When supplying a herbal remedy, complementary therapy or other healthcare product, sufficient information about the product must be provided in order for the purchaser to make an informed choice with regard to efficacy of the product and the risks and benefits of all available treatment options.

Submission to the Pharmacy Council of New Zealand (New Zealand Medical Association)


The Pharmacy Guild

The Pharmacy Guild represents pharmacy owners in New Zealand. The Pharmacy Guild’s submission supports the Pharmacy Council’s proposed change:

We support the Council’s intentions of the proposed changes to clause 6.9 of the Code of Ethics 2011 (the Code).

Consultation on the proposed wording to clause 6.9 of the Code of Ethics 2011 (Pharmacy Guild)

The primary motivation for this support seems to be a combination of the “freedom of choice” argument I described above, and the potential for benefit described in the Society for Science Based Healthcare’s submission:

We believe that if pharmacists were prevented from selling natural products then patients wanting these products would continue to source them from somewhere. We consider that it is far safer for consumers to approach pharmacists for advice and that they purchase supplies of complementary medicines from a pharmacy rather than over the internet for instance, where the quality and safety of a product cannot always be guaranteed.

Consultation on the proposed wording to clause 6.9 of the Code of Ethics 2011 (Pharmacy Guild)


As well as these submissions, I have been made aware of a few more, mainly submitted by individuals. Of those I am aware of, such as Edward Linney’s submission, they are predominantly opposed to the change for many of the reasons described in these submissions. I am aware of one instance of an ex-pharmacist who supports that change who is now a practising homeopath and, scarily, was previously employed by the Pharmacy Council as their Professional Standards Advisor even while they were practising as a homeopath. However I don’t know if they have made a submission.

I’m also aware that the Pharmaceutical Society has made a submission. Whereas the Pharmacy Council regulates pharmacists, the Pharmacy Guild and Pharmaceutical Society are membership organisations; the Guild represents pharmacy owners and the Society represents pharmacists in general. Although I have tried to get in touch with them, I haven’t seen the Pharmaceutical Society’s submission and can’t provide comment. I will update this article if that changes.

However, I am aware that the Pharmaceutical Society has close ties to the New Zealand Medical Association, even to the point where they have a joint agreement for members to abide by both organisations’ codes of ethics. So I expect that if they have made a submission it may be along similar lines to the NZMA’s submission.

If anyone knows of any more information that I’ve missed in this article, please leave a comment below.

Ethical Pharmacy Practice 4: Paving the Way

This year has not been a good year for homeopathy. There have been many blows to the industry in the form of more research finding it ineffective, position statements from organisations of health practitioners discouraging its use, and successful complaints to regulatory authorities. And this trend shows no signs of abating.

In March, the Australian National Health and Medical Research Council (NHMRC) published their Statement on Homeopathy, following a rigorous review of the evidence encompassing over 50 systematic reviews. The conclusion was clear:

there are no health conditions for which there is reliable evidence that homeopathy is effective.

Statement on HomeopathyNational Health and Medical Research Council (Australia)

Most organisations of medical professionals have codes of ethics that make it clear prescribing or selling treatments which are not supported by evidence is unethical. Putting two and two together, these ethical standards and the clear findings of the NHMRC have prompted the Royal Australian College of General Practitioners (RACGP) to publish a position statement on homeopathy:

The RACGP supports the use of evidence-based medicine, in which current research information is used as the basis for clinical decision-making.

In light of strong evidence to confirm that homeopathy has no effect beyond that of placebo as a treatment for various clinical conditions, the position of the RACGP is:

  1. Medical practitioners should not practice homeopathy, refer patients to homeopathic practitioners, or recommend homeopathic products to their patients.
  2. Pharmacists should not sell, recommend, or support the use of homeopathic products.
  3. Homeopathic alternatives should not be used in place of conventional immunisation.
  4. Private health insurers should not supply rebates for or otherwise support homeopathic services or products

Position statement: homeopathyRoyal Australian College of General Practitioners

Following this, in an interview with Radio New Zealand the chair of the New Zealand Medical Association (NZMA), Dr Stephen Child, made the NZMA’s position clear:

Susie Ferguson: So Australian doctors being told not to be prescribing this, and they should come off the shelves as well so people couldn’t even buy them over the counter. Would you support that happening here?

Dr Stephen Child: Well yes, it’s an ineffective treatment. It’s basically giving a glass of water or a sugar pill to patients, and I think you would consider that unethical if I gave you a sugar pill and charged you eighty dollars for that.

Doctors Told to Stop Prescribing Homeopathic ProductsRadio NZ

Homeopathy has never been supported by evidence, but the recent findings from the NHMRC have strengthened the scientific consensus and allowed many organisations to take a stronger stance against it.

When there is also a clear ethical mandate not to promote or provide healthcare that is not supported by evidence, all it takes to put two and two together is a little courage.

Now, Kingsley Village Pharmacy in Australia is paving the way, stating that their “Homeopathic products [are] going in the bin”:

The owner of Kingsley Village Pharmacy, pharmacist Grant McGill, has explained why he made this decision:

I’ve never promoted or recommended these products but I’ve accepted them passively and I felt a bit hypocritical having them on the shelves.

I operate a bit differently to corporate chains and believe a pharmacy should be professional rather than a place selling a lot of cosmetics.

If someone comes in with sleep problems, I will look at what is known to help and address things like sleep hygiene issues, rather than recommending flower essences.

Pharmacist bins ‘crap’ homeopathic productsThe West Australian

When the Twitter account for the pharmacy was asked if they thought their customers would notice or care about the change, they said:

A tweet from Grant McGill echoed the same sentiment as the reason for this change:

Through the Society for Science Based Healthcare, I have called previously for New Zealand pharmacists to stop selling homeopathic products.

When I had an complaint upheld against an Auckland Pharmacy for a misleading display stand for the homeopathic product No-Jet-Lag, that pharmacy promised to remove the product from sale and I hoped that New Zealand pharmacists would follow their example.

But it isn’t feasible for me to complain about each and every homeopathic product sold in a New Zealand pharmacy (although that hasn’t stopped me complaining about some). New Zealand pharmacists need to follow Kingsley Village Pharmacy’s example and remove the products not because complaints have been upheld, but because there’s no evidence they work so it’s clearly the ethical thing to do.


The Pharmacy Council of New Zealand is the body legally responsible under the Health Practitioners Competence Assurance Act for setting standards of ethical conduct to be observed by pharmacists on this side of the Tasman. To this end, they have published a Safe Effective Pharmacy Practice Code of Ethics. Section 6.9 of this code is very clear when it comes to pharmacists’ ethical responsibilities surrounding evidence-based healthcare:

YOU MUST:… Only purchase, supply or promote any medicine, complementary therapy, herbal remedy or other healthcare product where there is no reason to doubt its quality or safety and when there is credible evidence of efficacy

Safe Effective Pharmacy Practice Code of EthicsPharmacy Council of New Zealand

Despite this, as mentioned in the Radio New Zealand interview with Dr Stephen Child from the NZMA, “In New Zealand, many pharmacies stock a range of homeopathic treatments”. When New Zealand pharmacists have been challenged on this point, their defences have ranged from bizarre misunderstandings of the evidence (e.g. “Auckland pharmacist Martin Harris says there is good evidence for homeopathy in the field of quantum physics”) to arguments that patient choice overrides their ethical responsibility:

But homeopathy is part of a holistic approach to healthcare, according to Auckland pharmacist Caleb Townsend, whose Lincoln Mall Pharmacy has qualified homeopaths onsite.

There is not one system that suits all people, Mr Townsend says in an email.

“Homeopathy is seen at this pharmacy as complementary to conventional medicine, in much the same way as acupuncture, vitamins and herbs are.”

Many patients believe homeopathy has been of benefit and they should be given the freedom to choose it if they want, he says.

“We have not yet become a society where cultural beliefs are legislated out of existence.”

Pharmacists Support Patient Choice with HomeopathyPharmacy Today

Dr Child provided a response to this line of argument in his interview:

Well, again as I say they argue that it’s mainly free trade basically, or a free market, so if people are willing to pay the money, and they think it works, then what are they doing that’s wrong?

And my problem with that argument though is to say that if they are telling the patient that it works then they are misleading in their advertising and even the Consumer Guarantee Act that it’s not allowed to mislead the consumer.

Second of all there’s an imbalance of a relationship when you come in to see a health practitioner and you’re the patient.

And thirdly when you’re suffering and you’re unwell you’re possibly not in a position to make an informed, balanced decision as a consumer. So I’m not even sure the free market argument would suggest that it would be legitimate practice.

The Society for Science Based Healthcare has also been in touch with Green Cross Health, an umbrella organisation that owns brands such as Unichem and Life Pharmacy and represents over 300 New Zealand pharmacies, to ask if they have a commitment to uphold section 6.9 of the Pharmacy Council’s code of ethics. Despite following up multiple times, the closest thing to a direct answer Green Cross Health has given to this question is:

While we support best practice we are also supportive of consumer choice.

Green Cross Health

The remaining defence of this practice is that pharmacists do more than provide healthcare, they also have to run a business. Following his Radio NZ interview, Dr Child alluded to this in an article from Pharmacy Today following his Radio NZ interview:

“Medically, it’s unethical to provide a treatment that’s not proven,” Dr Child says.

However, he has stopped short of telling pharmacies not to sell homeopathic products.

“It’s not really appropriate, I believe, for the medical profession to tell pharmacies how to run their business and how to act.”

Pharmacies have a difficult balance between providing healthcare and running a business, Dr Child says.

“It must be very difficult because they are a business as well.”

Homeopathy discredited again on both sides of the TasmanPharmacy Today

There is a range of behaviours among New Zealand pharmacies when it comes to promotion of homeopathy. Some few pharmacists refuse to sell the products at all, whereas many stock them but might not actively promote or recommend them. On the extreme end of this ethical scale, there are pharmacies like Lincoln Mall Pharmacy in Auckland, which promotes “homeopathic consultations” from homeopaths within the pharmacy, and Simillimum Pharmacy in Wellington, which describes itself as a “homeopathic pharmacy”.

The fact that there are some pharmacists who operate without relying on profits from selling homeopathic products indicates that it is entirely possible. Those pharmacists who passively sell them likely don’t rely on the profits made from those products as the difference between financial success and failure, so I’d hope they wouldn’t use higher profits as a justification for breaching their ethical obligations.

If any pharmacy has got to the level where their business would fail financially were it not for homeopathic products and services that they sell, then their business practices would blatantly violate their ethical responsibilities. I should think the risk of financial failure in a case like this should certainly not be an acceptable excuse for such unethical conduct.

Kingsley Village Pharmacy in Australia has set a great example for all pharmacists, having the courage to take a stand on ethics and stop selling homeopathic products. New Zealand pharmacists who currently have them on their shelves should follow in these footsteps.

To borrow Grant McGill’s words, pharmacists need to stand up for patient outcomes.

Press Council Complaint: Homeopathy in the Wairarapa Times-Age

In February this year, an article was published in the Wairarapa Times-Age (both in print and online) headlined Use of natural remedies is on the rise. The article discussed some specific cases of so-called “natural remedies” being used to treat serious diseases, such as intravenous vitamin C for leukaemia and homeopathy to treat various forms of cancer.

Except for a brief mention at the bottom of the article encouraging people with cancer to talk to their doctor before using any “alternative therapies”, there was no mention of the fact that none of the treatments discussed are supported by any reliable evidence. Instead, the article uncritically included various quotes such as this, from homeopath Claire Bleakley:

Featherston-based homeopath Claire Bleakley said she has treated cancer patients using similar natural remedies [to intravenous vitamin C] – significantly extending life expectancy.

She mentioned two of her patients in particular: A man with tumours who lived for seven years after being given two to live, and a woman with ovarian cancer who lived 15 years past her initial prognosis.

“There have been some exceptional results,” Mrs Bleakley said.

“We are indoctrinated to think chemotherapy is the only cure for cancer, but alternative [remedies] have been proven to be more life giving.”

Medical anecdotes such as these unfortunately tend to be very convincing despite the fact that they can also be completely misleading. The reasons why people might get better are varied and complex. Without running a controlled test, there’s no way to know whether or not a particular treatment contributed to an improvement in health. That’s exactly why we need to undertake rigorous clinical trials before we can say with confidence what the effects of any particular treatment are. It’s also why the Medicines Act prohibits the use of health testimonials like this in advertisements, although that restriction of course doesn’t extend to news articles in publications like the Times-Age.

I thought, and still do think, that the lack of balance in this article has the capacity to do serious harm. I wrote to the editor of the Wairarapa Times-Age to make my case, and to give some suggestions for how they might attempt to mitigate the damage this article could do, in a formal complaint:

To whom it may concern,

I am writing to you to make a formal complaint regarding the article “Use of natural remedies is on the rise” published in the Wairarapa Times-Age this morning:
http://www.nzherald.co.nz/wairarapa-times-age/news/article.cfm?c_id=1503414&objectid=11399310

This article uncritically promotes the use of so-called “natural remedies” such as vitamin C or homeopathy for the treatment of cancer. They are promoted by the inclusion of quotes such as “There have been some exceptional results”, regarding the treatment of cancer with homeopathic products.

None of the relevant controversy regarding these treatments is discussed in the article. Although there is a brief note at the end that “those living with cancer [are encouraged] to consult their doctor or specialist before embarking on any alternative therapies”, this does not sufficiently address the important and relevant fact that these treatments are entirely unsupported by scientific evidence, as well as the utter implausibility of treatments like homeopathy.

The failure to discuss the lack of scientific evidence supporting these treatments, as well as the complete lack of plausibility underlying homeopathy, violates the Press Council’s principle of “Fairness, Accuracy and Balance”. The description of this principle on the Press Council’s website states that:

“Publications should be bound at all times by accuracy, fairness and balance, and should not deliberately mislead or misinform readers by commission or omission. In articles of controversy or disagreement, a fair voice must be given to the opposition view.

Exceptions may apply for long-running issues where every side of an issue or argument cannot reasonably be repeated on every occasion and in reportage of proceedings where balance is to be judged on a number of stories, rather than a single report.”

This is not a long-running issue in which readers can readily be expected to be familiar with the lack of evidence supporting the treatments discussed in the article, so the exception should not apply. There is significant controversy surrounding the issues discussed in this article, but a fair voice has not been given to the opposition view.

Particularly as this article could lead to people living with serious diseases such as cancer to rely on ineffective treatments such as homeopathy, its lack of balance has the potential to cause real and serious harm. Therefore it is important that the Wairarapa Times-Age take appropriate action to prevent this harm by amending the article, publishing a prominent correction, or publishing a followup article linked to from today’s article, that discusses the lack of evidence and plausibility underlying the treatments discussed in today’s article.

If the Wairarapa Times-Age has trouble finding any experts to talk to about this topic, either the Society for Science Based Healthcare (http://sbh.org.nz/contact) or the Science Media Centre (http://www.sciencemediacentre.co.nz/contact-us/) will be able to help.

Sincerely,

Mark Hanna
Society for Science Based Healthcare

Despite sending a follow-up email a few days later, I still hadn’t heard back from the editor over the next 10 working days, which is the deadline set in the Press Council’s complaints process as the time to wait before escalating a complaint to them if you don’t hear back from the editor. After I forwarded my complaint to the Press Council, the editor contacted me to apologise that he’d overlooked my complaint messages, which was apparently due to his having to deal with another complaint about the same article from Peter Griffin, manager of the Science Media Centre (Peter is also the editor and manager of Sciblogs, where my blog is syndicated, and we’d discussed our complaints via email prior to submitting them).

When I forwarded my complaint to the Press Council, I fleshed it out a bit more. I won’t quote the whole thing here as a lot of it would just be repeating myself, although I’d be happy to share my full complaint if anyone would like to see it, but here is one part I added that I think is important and worth sharing:

As far as I’ve been able to tell, the Wairarapa Times-Age has not published a large number of articles regarding this, so it cannot be argued that the counterpoints have already been published in earlier articles.

When it comes to whether or not readers can be expected to be familiar with the important facts not mentioned in this article, I would like to bring the Press Council’s attention to a 2009 study (I am not aware of any more recent data collected on this) published in the New Zealand Medical Journal entitled “Beliefs about homeopathy among patients presenting at GP surgeries”. This study can be accessed for free on Page 94 of this PDF:
http://www.nzma.org.nz/__data/assets/pdf_file/0010/17794/Vol-122-No-1295-22-May-2009.pdf

This study found that only 8 out of 124 respondents disagreed to some extent that “There is good scientific evidence that homeopathy works”, and only 24 respondents reported that they believed homeopathic products were either “very dilute” or that there was “nothing there”. In contrast, 82 respondents agreed to some extent that “There is good scientific evidence that homeopathy works”, and 80 believed that homeopathic products are either “Very concentrated”, “Moderately concentrated”, or “Moderately dilute”.

Contrary to these common beliefs, most homeopathic products are diluted to the point that it is astronomically unlikely that there is even a single molecule of the original ingredient present in the product, and there effectiveness is thoroughly unsupported by scientific evidence. For example, a rigorous review undertaken by the Australian Government’s National Health and Medical Research Council (NHMRC) in 2013 investigated the evidence regarding homeopathy for 68 clinical conditions and concluded that “The available evidence is not compelling and fails to demonstrate that homeopathy is an effective treatment for any of the reported clinical conditions in humans”
(https://www.nhmrc.gov.au/_files_nhmrc/file/your_health/complementary_medicines/nhmrc_homeopathy_overview_report_october_2013_140407.pdf)

For this reason, and especially because the article discussed the use of ineffective therapies in the treatment of terminal illness, it is very important that stories such as this be balanced. As I stated in my original complaint to the editor, I believe the article in its current form has the capacity to do serious harm and that the Wairarapa Times-Age has a responsibility to mitigate this harm. An appropriate response would be amending the article, publishing a prominent correction, or publishing a followup article linked to from the article from the 10th of February that discusses the lack of evidence and plausibility underlying the treatments discussed in today’s article.

(The NHMRC link I provide there is from their 2013 conclusion. Within 2 weeks of submitting this complaint, however, they released their final statement on homeopathy, which states “there are no health conditions for which there is reliable evidence that homeopathy is effective”. This statement was not reported in the Wairarapa Times-Age)

Once the complaint was escalated to the Press Council, the editor of the Times-Age was given an opportunity to respond, then I had a final opportunity to write a short response to that. His primary argument was that the topic of “alternative medicine” was a long-running issue in a wider context, and that the exemption to the principle of balance should apply because other media have reported on the opposing side of the issue.

I strongly disagree with this argument. Although it’s true that media like the Wairarapa Times-Age do not exist in a vacuum, I don’t think this should mean that they don’t have a responsibility to provide balanced articles for their readers. The way I interpret the Press Council code, the exception can be useful when an article is part of a series of articles on the same issue, and when taken in the context of other articles in the series the overall view still maintains an appropriate balance. In the interest of balanced reporting, I believe exceptions to the principle of balance should be applied very sparingly.

Unfortunately, the Press Council disagreed with me. They have ruled not to uphold the complaint, and you can view their entire decision on their website here:
Case Number: 2426 MARK HANNA AGAINST WAIRARAPA TIMES-AGE

Here’s a link to their similar ruling regarding the complaint from the Science Media Centre:
Case Number: 2425 SCIENCE MEDIA CENTRE AGAINST WAIRARAPA TIMES-AGE

Here is a summary of their decision:

The Press Council agrees with the editor that the debate over alternative remedies is sufficiently well known not to require balancing comment in every story about them. The subject falls within the exception to the principle of balance for issues of enduring public discussion.

The complainant in this case raised the important question of whether the exception can be invoked for an article in a newspaper that may not itself have covered both sides of the debate. The Council considered this point closely and came to the view that the exception has not been applied as narowly as the complainant contends and should not be. A newspaper, even if it is the sole newspaper of its locality, does not exist in a vacuum. Its readers, meeting an uncritical story on the supposed popularity of homeopathy and natural remedies, are likely to be aware the efficacy of these treatments is strongly contested by medical science.

I think this is a very worrying precedent to set. Newspapers such as the Wairarapa Times-Age can now feel justified in publishing unbalanced articles on topics such as homeopathy without feeling bound to uphold the Press Council’s principle of balance. The public have a reasonable expectation, given that the Press Council exists to uphold standards in reporting and its first principle is that articles should be accurate, fair, and balanced. While it’s a good idea to take everything you read with a grain of salt, you should be able to feel justified in expecting media reports on controversial topics to provide a balanced view. I worry that people might read articles such as this with that assumption in mind, and falsely conclude that the views omitted from the article are not merited.

I’m also rather frustrated that the Press Council concluded that anyone reading articles such as this is “likely to be aware the efficacy of these treatments is strongly contested by medical science” even though I provided data from a survey that found only 6% of respondents disagreed that “there is good scientific evidence that homeopathy works”. I understand that the survey I cited was conducted 6 years ago, but as I said in my complaint I’m unaware of anything more recent.

Although I don’t think it is, I really hope that the Press Council’s conclusion that most people are aware that homeopathy is not supported by evidence is correct. Following last year’s story about Green MP Steffan Browning backing homeopathy for ebola and March’s story about the Australian National Health and Medical Research Council concluding that homeopathy does not improve people’s health, I think there is some basis to believe that more people are familiar with the lack of evidence surrounding homeopathy than 6 years ago, but I don’t expect there would be that large a difference.

One positive thing to take away from this, at least, is that the journalist who wrote the article said in a Facebook comment that she understood the article was unbalanced and that she should have done better. I hope she’ll take this as a learning experience and, when she or other Wairarapa Times-Age reporters write on matters of “natural health” in the future, that they get in touch with the Science Media Centre to provide that much-needed balance. If we can’t rely on the Press Council to hold journalists to a high standard of balanced reporting, then we’ll have to rely on journalists’ and editors’ own standards.

Finding Power and Balance: Proving and Disproving Claims

I’m very happy to have had an article published on the website of the New Zealand Science Teacher, the official publication of the New Zealand Association of Science Educators.

My article is about applied kinesiology, I’ve embedded the introduction below and you can read the whole thing on the NZST website: Finding Power and balance: proving and disproving claims

When reading a story about someone who has been scammed, it’s very easy to think ‘that could never happen to me’. From the outside, warning signs always appear obvious and the conclusion often seems untenable. It’s easy to assume that people who fall for scams or are otherwise misled must be unintelligent or gullible. The reality is less comfortable. We can all be fooled, even the best of us.

One historical example of someone very intelligent falling for what now seems to be clearly false, involves author and doctor Sir Arthur Conan Doyle, creator of Sherlock Holmes. Despite obviously understanding the principles of scepticism, Doyle became convinced in the early 20th century that fairies were real, based on a series of photographs of the “Cottingley Fairies”, which were revealed decades later to have been faked using paper cut-outs. Intelligence is no failsafe against being fooled.

More recently, many people, including Shaquille O’Neil and Bill Clinton, have been fooled by a plastic wristband: the makers of which claim it can improve a person’s strength and balance.

The ‘theory’ behind the tests used to promote these wristbands is also employed by various alternative health practitioners in attempts to evaluate treatment effects and to diagnose illnesses, allergies, and intolerances, despite the fact that there is no scientific proof behind it.

It’s known as ‘applied kinesiology’ and, if you don’t know any better, it can be very convincing.

100% Natural and Chemical Free

This afternoon, the Advertising Standards Authority released their decision to uphold an interesting complaint regarding advertisements for a couple of cleaning products on a website. Here is the ASA’s description of how the products were described on the website:

The Wendyl’s website (http://wendyls.co.nz/) for “100% natural cleaning and beauty products” advertised their products as having “all their ingredients listed and contain no fillers, chemicals or synthetics.”

The webpage for Wendyl’s Oxygen Bleach 1KG (sodium Percarbonate) stated, in part:

This is powdered hydrogen peroxide which is a greener alternative to chlorine bleach because it breaks down to oxygen and water in the environment.

The webpage for Wendyl-San oxygen soaker 1KG stated, in part:

I’ve spent years testing this oxygen soaker and stain remover and I’m so glad to have something which is so free of chemicals and additives. Secret ingredient is sodium percarbonate, a powdered hydrogen peroxide bleach which breaks down in the environment to oxygen and water…

The complainant, food scientist Claire Suen, said that they breached the Advertising Code of Ethics and the Code for Environmental Claims. This excerpt is, I think, a good summary of their complaint:

The advertiser uses words such as “100% natural”, and “contains no fillers, chemicals, or synthetics”.

However, the product in question is sodium percarbonate, which is not a naturally occurring product. The main active ingredient, hydrogen peroxide, is also not a naturally occurring product and it is not stable in nature.

Both are synthetic chemicals.

After hearing from the advertiser as well, the Advertising Standards Complaints Board sided with the complainant. Here is a summary from the headnote of their decision:

The Complaints Board said it accepted the Advertiser’s view that “sodium percarbonate is a much safer and more environmnetally friendly alternative to chlorine bleach” but not that it was “chemical free” and “100% natural.” The Complaints Board said the advertisement was likely to mislead consumers into thinking the products were “100% natural” and “chemical free” when they actually contained naturally occurring chemicals, in breach of Principle 2 of the Code for Environmental Claims and had not been prepared with a due sense of social responsibility to consumers in breach of Principle 1 of the Code for Environmental Claims.

Accordingly, the Complaints Board ruled to Uphold the complaint.

The most interesting part of this complaint is, I think, who the advertiser is. As well as selling cleaning and beauty products online, Wendyl Nissen writes a weekly column for the New Zealand Herald called “Wendyl Wants To Know“. The Herald describes the column as:

Each week, Wendyl Nissen takes a packaged food item and decodes what the label tells you about its contents.

Have a look for yourself, but from the columns of hers that I’ve read it seems the main argument is typically along the lines of “natural is good, chemicals are bad”. So I find it very ironic that she’s now had a complaint upheld against her for misleadingly claiming that a product she sells is “100% natural” and “chemical free”.

For a counterexample to the attitude of “natural is good, chemicals are bad”, you need look no further than the “recipes” section of her website. There, she has some pet recipes which she makes available for free including one for De-Flea Powder for Cat Biscuits and another for Doggy De-Flea Treats. In both recipes, she claims the active ingredients are yeast and garlic:

The theory behind this powder is that fleas hate the taste of yeast and garlic so will hop off and look elsewhere.

Elsewhere on her website, she recommends that if you:

Put a garlic clove in your pet’s water you can help deter pests such as mites and fleas.

Although it certainly is natural, garlic is also toxic to cats and dogs, especially for cats. I couldn’t find any warnings about this on Wendyl Nissen’s website.

The lessons to be learned? Natural isn’t always good, and don’t take advertisers’ word for it when they claim something is “100% natural” or “chemical free”. As always, ask for evidence.

Ethical Pharmacy Practice 3: Running Out of Excuses

Ethical pharmacy practice is something I have written about before. If you’ve read those posts, please bear with me as I cover some familiar background.

In New Zealand, we are lucky enough to have an industry code of ethics for pharmacists, published by the Pharmacy Council of New Zealand, which holds pharmacists to high ethical standards. This code of ethics is the Safe Effective Pharmacy Practice Code of Ethics. One of the most important parts of this code of ethics is section 6.9, which states:

[PHARMACISTS] MUST:… Only purchase, supply or promote any medicine, complementary therapy, herbal remedy or other healthcare product where there is no reason to doubt its quality or safety and when there is credible evidence of efficacy.

Pharmacy Council’s Safe Effective Pharmacy Practice Code of Ethics Section 6.9

The Pharmacy Council of New Zealand isn’t a voluntary member organisation like the Pharmacy Guild or the Pharmaceutical Society. Instead the council is established as part of the Health Practitioners Competence Assurance Act 2003. Their roles are set out in this act and include:

  • Registering pharmacists
  • Reviewing and maintaining the competence of pharmacists
  • Setting standards of clinical competence, cultural competence, and ethical conduct for pharmacists

Which means that the Safe Effective Pharmacy Practice Code of Ethics is not a voluntary code of ethics. It is published by the body whose legal duty it is to set the standards of ethical conduct for pharmacists. Yet all over New Zealand, many pharmacists ignore it.

Walk into any New Zealand pharmacy. Chances are that you will find a section where they advertise and sell a range of homeopathic products. To anyone familiar with the evidence for homeopathy, it will come as no surprise when I tell you that there is no credible evidence of efficacy for any homeopathic product. Therefore, it seems to me, New Zealand pharmacists have an ethical obligation not to promote or sell them.

Yesterday, the Australian National Health and Medical Research Council (NHMRC) issued their final statement on homeopathy, following an incredibly extensive and rigorous review of the literature. They looked at over 1,800 scientific papers, and found that 225 met their criteria for methodological rigour, sample size, and placebo control. Their main finding was:

there are no health conditions for which there is reliable evidence that homeopathy is effective.

NHMRC Statement: Statement on Homeopathy

As I said, this conclusion does not come as a surprise. This research is the latest in a long line of reviews of the evidence for homeopathy that drew essentially the same finding:

  • A 2002 systematic review of systematic reviews of homeopathy published in the British Journal of Clinical Pharmacology concluded that:

    the hypothesis that any given homeopathic remedy leads to clinical effects that are relevantly different from placebo or superior to other control interventions for any medical condition, is not supported by evidence from systematic reviews. Until more compelling results are available, homeopathy cannot be viewed as an evidence-based form of therapy.

    A systematic review of systematic reviews of homeopathy

  • A 2010 systematic review of systematic reviews of homeopathy published in the Medical Journal of Australia concluded:

    The findings of currently available Cochrane reviews of studies of homeopathy do not show that homeopathic medicines have effects beyond placebo.

    Homeopathy: what does the “best” evidence tell us?

  • A 2010 report from the UK House of Commons concluded:

    homeopathy is a placebo treatment.

    Evidence Check 2: Homeopathy

  • In 2013, the NHMRC published a report based on their research that found:

    There is a paucity of good-quality studies of sufficient size that examine the effectiveness of homeopathy as a treatment for any clinical condition in humans. The available evidence is not compelling and fails to demonstrate that homeopathy is an effective treatment for any of the reported clinical conditions in humans.

    Effectiveness of Homeopathy for Clinical Conditions: Evaluation of the Evidence

I could go on, but I hope by now you get the idea.


New Zealand pharmacists need to respond to the NHMRC’s research. And if they mean to practice responsibly and ethically, that response should be to immediately stop all promotion and sale of homeopathic products. The ethical standard to which they should be held is clear, and it is not consistent with promoting or supplying homeopathic products.

Last year, I complained to the Advertising Standards Authority under the auspices of the Society for Science Based Healthcare about a homeopathic product for preventing jet lag (No-Jet-Lag) that was advertised in Parnell Pharmacy. The pharmacy responded by removing the advertisement, and agreeing to stop selling the product if it was found that the claims were not supported by credible evidence, and my complaint was upheld. Unsurprisingly, my complaint was upheld when the ASA decided claims such as “it really works” were not supported by credible evidence. However, despite Parnell Pharmacy’s example, many New Zealand pharmacies still sell this exact product.

The NHMRC’s report represents the same finding, but on a larger scale. New Zealand pharmacists who promote and sell homeopathic products should follow the responsible example of Parnell Pharmacy, and remove homeopathic products from their shelves.

When Marketing Trumps Science

Recently I’ve run across a couple of New Zealand companies that sell therapeutic products – one a weight loss pill, the other a jet lag drink – that seem to put marketing first and let science take the back seat. This is by no means new behaviour, but I want to use them as examples to illustrate this widespread problem and suggest what can be done to combat it.

Before promoting a therapeutic product, you should first have good reason to believe that it works. This, I hope, is common sense, but it’s also enshrined in the Fair Trading Act and the Therapeutic Products Advertising Code as they prohibit unsubstantiated claims. This means you have to test the product, and do so rigorously. Rigorous clinical trials are expensive to undertake though, so they’re quite a prohibitive first step.

Instead of jumping straight into the deep end, a useful first step can be to undertake a smaller and less rigorous (and therefore less expensive) experiment. In order to answer the question of whether or not a product actually works you need to conduct a more rigorous trial. There’s a great cost involved in doing this, but if the results of a preliminary trial are optimistic then you have reason to expect a more rigorous trial might give similar results, so the expense might be worth it. You may even be able to get some funding to help with a more rigorous trial on the basis that the preliminary results were positive.


This is what Tuatara Natural Products has been doing with their weight loss pill “Satisfax”. They have completed a low quality preliminary trial on their product, which has been colloquially dubbed the “Fat Mates” trial. Although I don’t believe it has yet been published in a journal at the time I’m writing this article, it was registered retrospectively in the Australian New Zealand Clinical Trials Registry: Effect of the dietary supplement Satisfax (Registered Trademark) on weight loss in overweight volunteers. Some information on the data in the trial can be found on their website as part of an analysis by Dr Chris Frampton: Analysis of Satisfax® Clinical trial

As you can see on the trial registration page, this was an uncontrolled trial on overweight adults. The original plan was to recruit 100 volunteers with the hope that at least 60 will complete the trial. I have to say I’m a bit confused about how many people were in the trial, as apparently the recruitment was increased to 200 applicants after applications opened (a change that has not been reflected in the trial’s registration) yet apparently about 400 people applied. One article claims there were 200 participants, a later media release from Tuatara Natural Products seems to imply 100 were recruited, and the analysis of the trial says there were only 81 participants. Either way, 81 participants completed the full 8 weeks, and 52 of them took the recommended dose for the whole duration of the trial.

If there were 19 or 119 participants who didn’t complete the trial, the statistical analysis seems to ignore them with no justification given. This is unusual – a 19% drop out rate is significant and shouldn’t be swept under the rug. A lot of the time Tuatara also seems to ignore the 29 participants who didn’t drop out but also didn’t take the full dose for the whole duration.

The Science Media Centre posted the responses of 2 experts, Associate Professor Andrew Jull and Professor Thomas Lumley, to a press release from Tuatara Natural Products in February. It’s a good analysis of some of the weaknesses with the study, and I recommend you read it: Kiwi diet pill claims – experts respond

This trial was uncontrolled, and therefore also unblinded and unrandomised. As Professor Lumley explains, this is a problem if you want to draw strong conclusions from its results. It is of low methodological quality, but that’s okay. There is no problem with doing less rigorous trials first if they’re done in order to determine if more rigorous trials are necessary. Dr Glenn Vile, Chief Technical Officer of Tuatara Natural Products and the principal investigator for this study, wrote the following in a comment on a post on the “Fat Mates” trial by Dr John Pickering:

The Fat Mates trial was designed by clinical trial specialists to generate information about the Satisfax® capsules that would help Tuatara Natural Products plan a larger and longer double blind, cross over, placebo controlled trial.

We will use this information to proceed with the next clinical trial, but in the meantime we were so excited the weight loss achieved by most of our Fat Mates was much greater than the placebo effect seen in other weight loss clinical trials that we decided to launch the product so that anybody who is overweight can try Satisfax® for themselves.

Dr Glenn Vile

I think the first part of what I’ve quoted above describes exactly what Tuatara Natural Products should be doing. They’ve conducted their low quality trial, and intend to use its results to proceed with a larger, longer, and more rigorous clinical trial. This is the right way to proceed – they now have an indication that their product might be effective, so they should do the research to find out.

The problem is that that’s not all they’re doing. After performing only a small low-quality trial, they’ve released their product for sale online and have been making a lot of noise about it. In my opinion, they’ve been significantly overstepping the results of their clinical trial. For example, in his comment Dr Vile also said:

our initial trial has shown [Satisfax] to be extremely effective in some overweight people.

Dr Glenn Vile

In their media release on the 20th of February, they reported the average weight lost only by the 52 participants who took the full dose to completion (rounded up from 2.9 kg to “close to 3kg”) but not the average weight lost by all participants. They then reported in bold that the top 26 participants lost more weight, and the top two participants lost even more weight than that!

This cherry picking of the best results appears to have been part of Tuatara Natural Products’ marketing strategy for at least a few months now. In January, Stuff published an article on the trial highlighting the single person who lost the most while participating in it: Blenheim ‘fat mate’ loses 13.5kg in 8 weeks.

That article particularly highlights the person who lost the most weight out of all those in the trial, at 13.5 kg (confusingly, the maximum weight loss reported in the analysis of the trial’s results is 13.3 kg). However, she was one of only 2 participants who lost over 10 kg, and on average the 52 participants who took the recommended dose for the full eight weeks lost 2.9 kg. Losing 13.5 kg is very far from a representative example. I’m not surprised that they didn’t choose instead to focus on the participant who gained 1.2 kg despite taking the recommended dose for the whole duration, but that is actually much closer to the mean change in weight.

The article is, for all intents and purposes, one big testimonial in favour of Satisfax. It was an article, not an advertisement, which is important because in New Zealand it’s illegal to publish any medical advertisement that:

directly or by implication claims, indicates, or suggests that a medicine of the description, or a medical device of the kind, or the method of treatment, advertised… has beneficially affected the health of a particular person or class of persons, whether named or unnamed, and whether real or fictitious, referred to in the advertisement

Medicines Act 1981 Section 58(1)(c)(iii)

This effectively bans all health testimonials from advertisements. I think this is a good part of the law, as testimonials can be both very convincing and completely misleading; a quack’s dream. Banning them should force businesses to instead focus on the results of research on their products, but this hasn’t stopped Tuatara Natural Products from getting stories written about the most extreme testimonials they could find from people who have lost weight at the same time as they were taking Satisfax.

More recently, Tuatara Natural Products has put out a press release multiple times (at least on the 20th of February and again on the 4th of March) that I think rather oversteps the results of their small preliminary trial:

A NEW ZEALAND SOLUTION TO A GLOBAL PROBLEM A little pill is providing an exciting answer to one of the worlds greatest and fastest growing problems: Obesity.A NEW ZEALAND SOLUTION TO A GLOBAL PROBLEM

A little pill is providing an exciting answer to one of the world’s greatest and fastest growing problems: Obesity.

Press Release – Tuatara Natural Products

I simply don’t think they are at all justified in saying that their new product is “providing an exciting answer to… Obesity”. They are putting marketing ahead of science, and that’s not okay.


Another company that seems to put marketing before research is 1Above. They make a drink which they claim can help you recover faster from jet lag, and have recently been in the news for signing a sponsorship deal with the fantastically successful golfer Lydia Ko.

At the end of that article about their sponsorship deal the reporter, Richard Meadows, made some comments regarding the science behind jet lag relief products and asked some good questions of 1Above’s CEO, Stephen Smith (emphasis mine):

[1Above’s] product contains a mixture of vitamins B and C, electrolytes, and Pycnogenol, a pine bark extract.

The efficacy of flight drinks to combat the effects of jetlag is unproven.

Late last year pharmacists were warned after the Advertising Standards Authority upheld a complaint against an ad saying a homeopathic anti-jet lag pill really worked.

[1Above CEO Stephen] Smith said 1Above would not be doing clinical trials, which were highly expensive and not necessary.

“What we tend to use is testimonials from people who have used the product and swear by it.”

Smith said the key ingredient, Pycnogenol, had itself had been tested in dozens of trials, including its effects on reducing jetlag.

Kiwi startup 1Above signs golf No 1 Lydia Ko

Yes, you read that correctly. The CEO of 1Above literally said that they won’t be doing clinical trials because they are “not necessary” and that they use testimonials instead.

As I said before, using testimonials to promote a therapeutic product, like a drink to help you recover faster from jet lag, can be both very convincing and completely misleading. There’s a reason why testimonials implying health benefits are illegal in New Zealand, and I hope that 1Above’s marketing will not violate this regulation.

Not all testimonials are prohibited, of course. It’s entirely acceptably to provide a testimonial from someone who thinks their drink tastes great, or that they provide great service. Basically anything for which a single person’s experience can provide a useful insight. Therapeutic effects, almost without exception, do not fall into this category, which is a big part of why we need to do clinical trials in the first place. If they quote someone in saying that their product helped them recover faster from jet lag, they may be in danger of breaching the Medicines Act.

For example, I’d expect they probably shouldn’t use a testimonial that says this:

Testimonial on the 1Above website, collected 2015/03/05
Testimonial on the 1Above website, collected 2015/03/05

On their website, 1Above currently does refer to research on one of the ingredients in their product, “pycnogenol”. Professor Lumley recently wrote a post about this on his other blog, Biased and Inefficient, regarding these studies and how they are used by 1Above: Clinically Proven Ingredients

I recently contacted 1Above to ask about some discrepancies I found between the abstract of the study they cited for showing pycnogenol reduced the duration of jet lag and their description of it on their website:

I was interested to see the claim your company made that Pycnogenol® has been shown to support circulation and reduce the length and severity of jet lag.

I have found the study “Jet-lag: prevention with Pycnogenol. Preliminary report: evaluation in healthy individuals and in hypertensive patients” that is mentioned on your website as the source for this claim, but I am only able to access the abstract of this preliminary report. Unfortunately, as far as I can tell, the study protocol didn’t involve blinding of participants or researchers.

The participants in the study took 50 mg Pycnogenol 3 times per day, but I haven’t been able to find out how much is contained in your products. Is this information available anywhere on your website? I notice the study also says the participants took this regimen for 7 days, starting 2 days prior to departure. Is this comparable with how your product is intended to be used?

I also noticed some differences between the description of the study and its results between the abstract and your website, I would be grateful if you could explain to me the source of these differences.

The abstract states the control group took, on average, 39.3 hours to recover and the experimental group took, on average, 18.2 hours to recover. However your website reports these as 40 and 17 hours respectively.

Also, your website states that the study involved 133 passengers (it’s not clear from the description on your website if they all took Pycnogenol or if some of them were in the control group) who reported the time it took them to recover from jetlag. However, the study’s abstract states that in the first experiment, which is the only one that involved the reporting of the time taken to recover from jetlag, only involved 68 participants – 30 in the control group and 38 in the experimental group.

I would be grateful if you could explain these differences to me, and if you could send me any other relevant scientific information that supports this claim.

To their credit, since receiving my message they did update their website to fix the discrepancies in the reported number of participants and times taken to recover from jet lag, and their CEO replied to thank me for pointing these discrepancies out.

However, they didn’t respond to my other questions about the amount of pycnogenol in their products or the study involving the participants taking pycnogenol for 7 consecutive days, starting 2 days before their flight, which is inconsistent with how 1Above recommends their products be used.

This is just one more company basing their marketing on preliminary trials instead of using them as the basis for research that could actually answer the question of whether or not a product is useful. Worse than Tuatara Natural Products, they even go so far as to consider clinical trials “not necessary” and apparently intend to rely on testimonials instead. It would be much more appropriate for them to spend some of their $2.4 million annualised income on researching their product rather than paying for a sporting celebrity to endorse them.


I try to make my rants constructive, so I want to end this article with the question “What can we do about this?”. If you have any suggestions, I’d love to hear them in the comments section.

I think the most important thing that anyone can do to address this problem is to ask for evidence. If you see a claim made about a product that you think you might buy, then get in touch with the company selling it to let them know you’re considering buying it and to ask for evidence. If they don’t have a good enough answer, then let them know that’s why you won’t be buying their product. If they give you evidence to back up their claim, then great!

The UK organisation Sense about Science has created a website for just this purpose: www.askforevidence.org

Asking for evidence doesn’t have to be a big deal, involving a formal letter or anything like that. When you see a weight loss product advertised on a one day deal site, a copper bracelet that apparently offers pain relief advertised on a store counter, or a jet lag cure promoted on Twitter, make your first response be to politely ask for evidence.

This isn’t a problem that’s going away any time soon. As consumers, we deserve to be able to make informed decisions about the products we buy, and when companies put marketing before research it becomes harder to make these informed choices. But if we work together then we can encourage companies like Tuatara Natural Products and 1Above to improve their behaviour and attitudes toward marketing and research.

Let’s turn “what’s the evidence?” into a frequently asked question for all companies that sell therapeutic products.

New Zealand Skeptics Conference: Fighting Pseudoscience

Over the weekend, I attended the New Zealand Skeptics Conference at Auckland University. It was a great weekend, with consistently good speakers. Not only did we have the hosts of the popular Skeptics Guide to the Universe podcast and George Hrab from the Geologic podcast over from America, we also had a lot of fantastic local speakers like Nicola Gaston and Michelle Dickinson (Nanogirl).

If you weren’t able to attend and want to know what you missed, the conference program is currently still available online. I think the website will be reused for next year’s conference in Christchurch though so that won’t last forever.

As well attending some really great talks, I was also able to meet a lot of people who I’d previously only spoken to online. Nicola, Michelle, Jonny, Will, and everyone else I met over the weekend, it was wonderful to meet you all! I was also rather honoured to be given the “Skeptic of the Year” award at the conference dinner, for my consumer advocacy work and for helping to found the Society for Science Based Healthcare.

If you have a close look at the conference program, you might notice that I was scheduled to hold a workshop on “Fighting Pseudoscience” on the Saturday afternoon. As I have done with my previous talk at Auckland Skeptics in the Pub, I’d like to put my slides from this up online. Here they are:

If you view them on Google Drive (click the “Google Slides” link in the lower right) you’ll also be able to see my notes for each slide.

I think the workshop went really well, there was a lot of good discussion with the audience and I hope I was able to motivate some of them enough to make complaints of their own. Unfortunately I was only able to get through a single example in the time I had instead of the four I had prepared, but that was due to the time spent in discussion with the audience so it wasn’t really a problem.

Siouxsie was kind enough to get a few copies of the Ponsonby News (which it’s always fun to hear her rant about on the Completely Unnecessary Skeptical Podcast) to pass around the audience, and a few people found advertisements in the health section that seemed likely to be misleading.

There were also a couple of copies of the Advertising Standards Authority’s Codes Booklet that I was able to pass around the audience (thanks to Lisa Taylor for letting me borrow her code booklet for this). A few people asked me afterwards how they could get one of these booklets. One option would be to email the ASA to ask for one or to tick the box asking if you’d like one when you submit a complaint online. Another option is to print the PDF yourself. The ASA’s codes are all available on their website too, so don’t feel like you have to print the PDF if you’re happy to use an online reference.

Finally, everyone who attended my talk got a copy of a “Complaining Cheat Sheet” that I’d put together for the Society for Science Based Healthcare (thanks to Nancy Lan for helping me a lot with the design). The idea behind this was that it can feel like quite a task to go through the ASA’s codes to find out which sections of which codes an ad might violate, especially if you’re not already familiar with them. This cheat sheet can serve as a quick reference to some of the most commonly violated sections of the ASA’s codes, as well as a guide to how to prepare and submit a complaint.

I’ve embedded the complaining cheat sheet below, and it’s available via the Society for Science Based Healthcare’s website: Complaining Cheat Sheet

Please download it, print it, share it widely, and most importantly use it. It was made to make it easier for anyone to complain about misleading advertising in New Zealand, so the next time you see an ad that you think is misleading, instead of just being annoyed try complaining. Together we can make New Zealand a safer environment for consumers.

Copper & Magnetic Healing: How to Respond to Complaints

Last Saturday, I was in a store that had a display on their counter advertising copper and magnetic jewellery:

Copper & Magnetic Healing

As you may be aware, claims that copper jewellery are able to help with arthritis are relatively common, although the evidence is pretty negative. The claim about magnets attracting iron in your blood and thereby increasing circulation is pure pseudoscience though. Usually, if I do something about an ad like this, I lay a complaint directly with the Advertising Standards Authority. This time though, I thought I’d try directly contacting the store to see if they’d fix this situation without requiring any regulatory intervention.

You can read the full email I sent to the company at the bottom of this post, but essentially I described the regulations around claims in advertising needing to be substantiated, and gave some evidence that these claims probably weren’t substantiated. Here’s what I recommended as a course of action:

I understand that these claims were likely supplied to [your store] by the supplier of the copper and magnetic jewellery, and that no one at [your store] has had any intention of misleading your customers. I recommend that you immediately remove the “Copper & Magnetic Healing” display, and contact the manufacturer to ask them for evidence to substantiate these claims. Unless you are in possession of such evidence, you should avoid making therapeutic claims regarding these products.

I’ve had a wide variety of responses from my ASA complaints in the past, so I wasn’t sure how I should expect this business to respond. To make sure my email wouldn’t just be ignored, I asked them to get back to me within a week to let me know what they’d do, so I could know whether or not I should complain to the ASA.

In this case, I was very impressed to hear back from them the next day to tell me that the stores had been advised to remove the displays and they would contact their supplier to ask for evidence to substantiate the claims they’d provided. They also seemed to realise that the chance of the supplier being able to give the kind of evidence required was pretty slim.

A couple of days after that, I heard back from them again to confirm that, as expected, their supplier was unable to provide evidence that would substantiate the claims made about the jewellery. Because of this, they told me that from now on they would only advertise them as jewellery – not “healing jewellery” or anything like that.

I’m very happy to have seen such prompt and responsible action taking following a complaint. I hope this can serve as an example to other businesses.


If you see a therapeutic claim advertised somewhere, and you think it might not be backed up appropriately by scientific evidence, perhaps consider doing something about it. A good start could be to just ask for evidence. If you’d like them to remove a claim if it turns out not to be backed up by evidence, you can recommend that they do this (and your recommendation will be backed up by the Fair Trading Act).

If they refuse, which I would hope is unlikely, then you could lay a complaint with the ASA. The ASA requires that advertisers must be able to substantiate therapeutic claims that they make; it’s not up to you to prove them false, it’s up to advertisers to prove them correct.

If you do contact a business about a claim they’re making, I would suggest a few things:

  1. Be polite. This costs you nothing, and if you come across as rude or antagonistic it’s not going to lead to a productive exchange.
  2. Recommend a course of action. Ideally make it something that is easy for the business to do.
  3. Give an ultimatum. This should still be polite, but I would recommend asking the business to tell you what they’re going to do within a certain timeframe (such as one week) so you’ll know whether or not it’s necessary to bring their claim to the attention of the Advertising Standards Authority.

If you’re interested in doing something about a dodgy medical claim, the Society for Science Based Healthcare can help you to understand the regulation and put together a complaint.


This is the email I sent to the store on Sunday, with the name of the store removed:

To whom it may concern,

I was in [your store] earlier today, and I noticed a display for copper and magnetic bangles and rings on the counter (see photograph attached).

This display contained a number of therapeutic claims about the products. As I hope you are aware, the Advertising Standards Authority requires that all therapeutic claims made in advertisements must be truthful and have been substantiated (see their Therapeutic Products Advertising Code Principle 2). Similarly, the Fair Trading Act 1986 Section 12A states that unsubstantiated representations must not be made in trade.

To my knowledge, none of the therapeutic claims made on the display are substantiated.

A systematic review of the evidence regarding the use of static magnets for reducing pain, published in 2007, found that “The evidence does not support the use of static magnets for pain relief, and therefore magnets cannot be recommended as an effective treatment.”

Relatively little research has been done on the use of copper bracelets for pain relief, but a well-designed trial published in 2009 found that “Our results indicate that magnetic and copper bracelets are generally ineffective for managing pain, stiffness, and physical function in osteoarthritis. Reported therapeutic benefits are most likely attributable to non-specific placebo effects.”

The Advertising Standards Authority upheld a complaint in 2013 against claims made on the Woolrest Biomag website, partly due to the fact that their claims that the magnets in their products can increase circulation by “drawing trace elements, for instance, iron, towards the magnets” and by causing “blood vessels to dilate” did not appear to be supported by any evidence and were therefore likely to mislead consumers.

I understand that these claims were likely supplied to [your store] by the supplier of the copper and magnetic jewellery, and that no one at [your store] has had any intention of misleading your customers. I recommend that you immediately remove the “Copper & Magnetic Healing” display, and contact the manufacturer to ask them for evidence to substantiate these claims. Unless you are in possession of such evidence, you should avoid making therapeutic claims regarding these products.

Please reply to this email by the 23rd of November to inform me of what action you will be taking, so I will know whether or not it will be necessary for me to lay a complaint to the Advertising Standards Authority to settle this matter.

Sincerely,

Mark Hanna
