New RCP report says ecigs should be promoted to smokers to help them quit

A new report released today from the Royal College of Physicians, ‘Nicotine without smoke: tobacco harm reduction’ concludes that e-cigarettes are likely to be beneficial to UK public health. Smokers can therefore be reassured and encouraged to use them, and the public can be reassured that e-cigarettes are much safer than smoking.

Tobacco smoking is addictive and lethal. Half of all lifelong smokers die early, losing an average of about 3 months of life expectancy for every year smoked after the age of 35, some 10 years of life in total. Although smoking prevalence in the UK has reduced to 18%, 8.7 million people still smoke. Harm reduction provides an additional strategy to protect this group of smokers from disability and early death.

Since e-cigarettes became available in the UK in 2007, their use has been surrounded by medical and public controversy.  This new 200-page report examines the science, public policy, regulation and ethics surrounding e-cigarettes and other non-tobacco sources of nicotine, and addresses these controversies and misunderstandings with conclusions based on the latest available evidence:

  • E-cigarettes are not a gateway to smoking – in the UK, use of e-cigarettes is limited almost entirely to those who are already using, or have used, tobacco
  • E-cigarettes do not result in normalisation of smoking – there is no evidence that either nicotine replacement therapy (NRT) or e-cigarette use has resulted in renormalisation of smoking. None of these products has to date attracted significant use among adult never-smokers, or demonstrated evidence of significant gateway progression into smoking among young people
  • E-cigarettes and quitting smoking – among smokers, e-cigarette use is likely to lead to quit attempts that would not otherwise have happened, and in a proportion of these to successful cessation. In this way, e-cigarettes can act as a gateway from smoking
  • E-cigarettes and long-term harm – the possibility of some harm from long-term e-cigarette use cannot be dismissed due to inhalation of the ingredients other than nicotine, but is likely to be very small, and substantially smaller than that arising from tobacco smoking. With appropriate product standards to minimise exposure to the other ingredients, it should be possible to reduce risks of physical health still further. Although it is not possible to estimate the long-term health risks associated with e-cigarettes precisely, the available data suggest that they are unlikely to exceed 5% of those associated with smoked tobacco products, and may well be substantially lower than this figure.

The report acknowledges the need for proportionate regulation, but suggests that regulation should not be allowed significantly to inhibit the development and use of harm-reduction products by smokers. A regulatory strategy should take a balanced approach in seeking to ensure product safety, enable and encourage smokers to use the product instead of tobacco, and detect and prevent effects that counter the overall goals of tobacco control policy.

Professor John Britton, chair of the RCP’s Tobacco Advisory Group, said:

‘The growing use of electronic cigarettes as a substitute for tobacco smoking has been a topic of great controversy, with much speculation over their potential risks and benefits. This report lays to rest almost all of the concerns over these products, and concludes that, with sensible regulation, electronic cigarettes have the potential to make a major contribution towards preventing the premature death, disease and social inequalities in health that smoking currently causes in the UK. Smokers should be reassured that these products can help them quit all tobacco use forever.’

RCP president Professor Jane Dacre said:

‘Since the RCP’s first report on tobacco, Smoking and health, in 1962, we have argued consistently for more and better policies and services to prevent people from taking up smoking, and help existing smokers to quit. This new report builds on that work and concludes that, for all the potential risks involved, harm reduction has huge potential to prevent death and disability from tobacco use, and to hasten our progress to a tobacco-free society. With careful management and proportionate regulation, harm reduction provides an opportunity to improve the lives of millions of people. It is an opportunity that, with care, we should take.’

Alison Cox, director of prevention for Cancer Research UK, said the charity believes e-cigs have a “real promise” in helping to reduce the death toll from tobacco.

She added: “This important report is an accurate summary of the latest scientific evidence on e-cigarettes and will help dispel the increasingly common misconception that they’re as harmful as smoking. They’re not.

“Tobacco kills more than 100,000 people in the UK every year, we should grasp every opportunity to encourage as many people as possible to stop smoking for good.”

And Duncan Selbie, chief executive at Public Health England, said the report highlights the “important role” of e-cigarettes in reducing the deadly harms smoking causes.

He added: “The best thing a smoker can do, for themselves and those around them, is to quit completely, now and forever.

“E-cigarettes are the most popular quitting aid in England and local stop smoking services are the most effective route to giving up, we encourage smokers to combine these, giving them an extremely good chance of quitting smoking successfully.”

Five researchers from the University of Nottingham were involved in the report.

These were Ilze Bogdanovica, research fellow; John Britton, professor of epidemiology; Tessa Langley, assistant professor in health economics; Sarah Lewis, professor of medical statistics; and Opazo Breton, research statistician.
