TGA overreacts to vaping study
Today's warning by the Therapeutic Goods Administration (1) about the 'serious health risks' from ecigarette liquid is disproportionate and misleading and will cause unnecessary alarm according to the health promotion charity, the Australian Tobacco Harm Reduction Association (ATHRA).
The warning was based on a study in the Medical Journal of Australia (2) which found traces of nicotine in a small number of supposedly 'nicotine-free' e-liquid samples. Trace amounts of several other chemicals were identified, one of which can irritate the lungs and skin.
According to Conjoint Associate Professor Colin Mendelsohn, chairman of ATHRA, the risk from the chemicals detected in the samples is trivial.
'The average concentration of nicotine found was about 15 times less than the average strength of nicotine used in vaping liquids. This dose is extremely small and is unlikely to have any significant effect on health'.
‘Trace amounts of several chemicals were also identified. It is impossible to say if these are toxic without knowing the dose and the level at which they cause harm. Neither were provided.’ he said.
‘To help people understand the real level of risk, the TGA warning should have included a comparison with the risks from smoking, which are infinitely greater’ Dr Mendelsohn said. Vapour is not risk-free and is known to contain low doses of chemicals. However, tobacco smoke contains over 7,000 chemicals and toxins in much higher doses and is far more harmful.’
The risk from long term vaping is likely to be no more than 5% of the risk from smoking according to the UK Royal College of Physicians (3) and Public Health England (4).
‘Smokers who switch to exclusive vaping are likely to have substantial health improvements. For many, this change will literally be lifesaving’ Dr Mendelsohn said.
'Managing the issue of nicotine contamination is simple', said Dr Joe Kosterich, a director of ATHRA. ‘E-liquids need to be legalised and regulated so that quality and safety standards can be applied. Currently there are no regulations at all.'
‘These e-liquid solutions could have been mixed in someone's kitchen sink without any care or expertise, with the same utensils used to make nicotine e-liquid.'
ATHRA believes that vaping products are consumer products which should be regulated by the Australian Competition and Consumer Commission not the TGA (5).
'The TGA is responsible for regulating medicines and medical devices and should not have a mandate over vaping products as they do not make therapeutic or medicinal claims' Dr Kosterich said.
