Re: E-cigarettes: relax rules to help more smokers quit, say MPs
The House of Commons Science and Technology Committee report on e-cigarettes is well worth reading.(1) The 98 pieces of published written evidence is a good place to start and have been produced by a range of individuals and organisations including: multinational tobacco companies, vaping organisations and public health groups.
We are concerned that the report from the Science and Technology Committee, repeats Public Health England’s claim that e-cigarettes are 95% less harmful than conventional cigarettes.(2) The use of such a statement will lead some people to think that e-cigarettes are quite safe. However, we believe it is far too early to devise a figure such as this when there is a lack of evidence on the long-term health consequences of e-cigarettes.(3,4)
It is basic but important to note that the lungs are delicate organs and have been designed to breathe clean air and any material inhaled long term may be harmful. So it should not surprise us if the long-term impact of the many different unregulated chemicals in e-cigarettes is negative on both individual and population health. We should learn from history - in relation to health, politics and economic interests.(5,6)
Already two very recent studies have had results that demonstrate adverse biological effects.(7,8) The first found that under laboratory conditions lung cells become inflamed when exposed to e-cigarette vapour.(7) Whereas, the second an observational study, concluded that “Daily e-cigarette use, adjusted for smoking conventional cigarettes as well as other risk factors, is associated with increased risk of myocardial infarction.”(8)
Besides safety issues another important consideration is efficacy of e-cigarettes - helping smokers to reduce consumption or quit altogether. A recent Cochrane Review found that there was little evidence that e-cigarettes are an aid to smoking cessation and recommended that further studies are needed.(9) We are therefore very concerned that the Commons Select committee website has the statement that “E-cigarettes are a proven stop smoking tool ….”(1)
The report also ignores the evidence that e-cigarettes can act as a gateway to conventional smoking, including for young non-smokers.(10) Use of e-cigarettes has increased rapidly over the past decade in the USA, particularly among young people. (10,11) We are alarmed at the rise in use of Juuls in some countries and worried that they may also become a cool lifestyle choice of young people in this country as well as a long-term serious risk to public health.(12-14)
Whilst we agree that smoking still “remains a national health crisis” particularly for certain groups within society, we do not believe that many of the steps in the report should be actively endorsed by the Government. We are surprised that unproven and potentially dangerous e-cigarettes are being promoted at a time when there have been substantial cuts to successful public health services including smoking cessation services.(15-17)
