Introduction 1.1 Aim of the report This is the sixth report in a series of independent reports commissioned by Public Health England to summarise evidence on e-cigarettes to inform policies and regulations. Despite reductions in smoking prevalence, smoking remains the biggest single cause of preventable death and disease and a leading cause of health inequalities. So, alternative nicotine delivery devices which are less harmful could play a crucial role in reducing this health burden. This report presents updates on the prevalence of vaping among young people and adults and reviews literature on vaping among people with mental health conditions and pregnant women. A comprehensive e-cigarette safety review will be the focus of a future report. 1.2 Terminology We use the term ‘vaping products’ to describe e-cigarettes and refill containers (e-liquids). We use the term ‘vapers’ to refer to people who regularly use vaping products and ‘vaping’ as the act of using a vaping product. Our terms do not include cannabis vaping or the vaping of other illicit substances, which are not the subject of this report. 1.3 Current regulations Non-nicotine containing vaping products fall under the General Product Safety Regulations 2005, enforced by local trading standards. Nicotine-containing vaping products are regulated more stringently through the revised European Union Tobacco Products Directive (2014/40/EU) (TPD), translated into United Kingdom (UK) law through the Tobacco and Related Products Regulations 2016 (TRPR), which the government has committed to review by May 2021. 8 Vaping in England 2020 There are no medicinally licensed nicotine vaping products in the UK. Selling vaping products to anyone under 18 is prohibited and so is buying vaping products for anyone under 18. 1.4 Recent developments Nicotine vaping products have continued to evolve. The use of nicotine salt technology is becoming more popular. Between 20 May 2016 (implementation of TRPR) and 9 January 2020, the Medicines and Healthcare products Regulatory Agency (MHRA) had received 84 reports of 245 adverse reactions believed to be associated with vaping products that contain nicotine through its Yellow Card Scheme. A report is not proof that the reaction was caused by a vaping product, just that the reporter suspected it might have been. In the US, where there is a very different regulatory system for vaping products (including products used to vape cannabis), there was a spate of serious lung diseases and deaths that appeared to peak in late 2019. This outbreak seems to have been caused by people vaping the cannabis derivative tetrahydrocannabinol (THC) oil and vitamin E acetate. There has been no similar lung disease outbreak in England, although the MHRA has received reports of 4 deaths through its Yellow Card Scheme where vaping was suspected to be implicated
