We can be confident that e-cigarette use results in much lower exposure to toxins for users.
“Although e-cigarette vapour may be an irritant to people in close proximity to the e-cigarette user, there is no evidence of harm from other people inhaling e-cigarette vapour unlike the known risks of second hand cigarette smoke. There is also as yet no evidence that e-cigarettes are renormalizing smoking.
“Based on their analysis, the WHO proposes a range of regulations for e-cigarettes and my concern is that these will deter smokers from trying to use them. Cigarette smoking is so uniquely dangerous that anything we can do to encourage smokers to stop should be welcomed. In the UK whilst we have achieved remarkable reductions in smoking over recent decades, smoking is now concentrated among our most disadvantaged groups in society, for whom I think e-cigarettes could be a game changer.”
