E-cigs safe and effective and widely used
Electronic cigarettes can help people stop smoking and are safer than real cigarettes according to a paper in the BMJ (https://doi.org/10.1136/bmj.j5543).
The technology used in e-cigarettes has evolved considerably over time, and newer devices are typically better at delivering nicotine, which might enhance effectiveness, says the review.
About 60% of current adult smokers in Great Britain have tried e-cigarettes and 18% are current e-cigarette users. In England, over 40% of people who try to stop smoking do so with the aid of e-cigarettes. Some people who stop smoking with an e-cigarette are still using e-cigarettes a year later. About 48% of current e-cigarettes users are not former smokers.
