The report covers e-cigarette use among young people and adults, public attitudes, the impact on quitting smoking, an update on risks to health and the role of nicotine. It also reviews heated tobacco products.

The main findings of PHE’s evidence review are that:
• vaping poses only a small fraction of the risks of smoking and switching completely from smoking to vaping conveys substantial health benefits
• e-cigarettes could be contributing to at least 20,000 successful new quits per year and possibly many more
• e-cigarette use is associated with improved quit success rates over the last year and an accelerated drop in smoking rates across the country
• many thousands of smokers incorrectly believe that vaping is as harmful as smoking; around 40% of smokers have not even tried an e-cigarette
• there is much public misunderstanding about nicotine (less than 10% of adults understand that most of the harms to health from smoking are not caused by nicotine)
• the use of e-cigarettes in the UK has plateaued over the last few years at just under 3 million
• the evidence does not support the concern that e-cigarettes are a route into smoking among young people (youth smoking rates in the UK continue to decline, regular use is rare and is almost entirely confined to those who have smoked)
