In 2008, a year after smoking was banned indoors across the UK, e-cigarettes hit the market. By 2019, according to a YouGov survey, more than 3.6 million adults in Great Britain were using e-cigarettes or vaping, a total of 7.1 per cent of the adult population. However, as relatively new products, there is very little long-term evidence on e-cigarettes, and many people remain unsure as to whether or not vaping may pose a risk to children, particularly as more and more stories about the dangers of vaping are now hitting the headlines.
