Replacing tobacco with electronic cigarettes is an effective method to stop smoking, according to a research conducted by Queen Mary University in London (UK).
The results of the clinical trial, published in the New England Journal of Medicine (NEJM), show that one year after starting treatment, 18% of smokers who used electronic cigarettes left, while among those who used conventional methods, such as adhesives or nicotine gum, only 10% did so.

"Although a large number of smokers claim to have been able to quit smoking with the help of electronic cigarettes, health professionals are reluctant to recommend its use lack of clear evidence of randomized clinical trials. That will probably change from now on, "said Peter Hajek, a researcher at Queen Mary University in London who led the research in a statement.
In the clinical trial 886 smokers participated who had gone to health centers for help getting out. The doctors randomly distributed them into two groups. In the first group, they received a nicotine replacement of their choice, such as stickers, chewing gum, tablets or inhalers, which should last up to three months. In the second group, smokers received an electronic cigarette kit with refills and were encouraged to buy the flavors they liked most on their own. In addition, all participants received support sessions with health personnel for four weeks.
