Tobacco substitution for electronic cigarettes is an effective method of stopping smoking, according to the conclusion of the survey led by Queen Mary University of London (United Kingdom).
Clinical trial results published in the New England Journal of Medicine (NEJM) show that one year after the onset of treatment, 18% of smokers who used electronic cigarettes left, whereas those who used the usual methods, such as patches or nicotine rubber, only achieved 10%.

"Although a large number of smokers claim to have successfully quit using electronic cigarettes, health professionals are reluctant to recommend their use due to lack of clear evidence of randomized clinical trials. That's likely to change since then, "said Peter Hajek, a researcher at Queen Mary University in London who led the research.
In the clinical trial In total, 886 smokers participated who went to medical centers to seek help to stop. Doctors distributed them randomly in two groups. In the first group they received a nicotine replacement of their choice, such as patches, chewing gums, pills or inhalers, which should last up to three months. In the second group, the smokers received an electronic cigarette set with refills and were encouraged to buy the tastes they liked most. In addition, all participants received support with healthcare personnel for four weeks.
