Substitution of tobacco for electronic cigarettes is an effective method of smoking cessationin accordance with an investigation conducted by the University of Queen Mary in London (United Kingdom).
The results of a clinical study published in the New England Journal of Medicine (NEJM) show that one year after the start of treatment, 18% of smokers who used electronic cigarettes had left, but among those who used the usual methods, such as a patch or nicotine resin, only 10% had reached it.

"Although a large number of smokers confirm that they have successfully stopped smoking using electronic cigarettes, healthcare professionals do not want to recommend its use there is no clear evidence of randomized clinical trials. It will probably change now, ”said Peter Hajek, a researcher at Queen Mary University in London, who led the study.
In a clinical trial 886 smokers participated who went to health centers for help seeking refusal. Doctors divided them into two groups at random. In the first group they received a nicotine substitute of their choice, such as patches, chewing gum, tablets or inhalers lasting up to three months. In the second group, smokers received an electronic cigarette set with refillers and were encouraged to buy the flavors they liked most. In addition, all participants received support sessions with healthcare staff for four weeks.

A year later, 10% smokers who had been treated with conventional nicotine substitutes had to quit smoking. For those who had received electronic cigarettes they got it almost twice, 18%.
The participants who failed to quit were among those who used electronic cigarettesEducate tobacco who smoked on the side. Electronic cigarettes also reduced cough and phlegm production more than other nicotine substitutes.

On the other hand, doctors observed more throat irritation the use of electronic cigarettes (14% more) and more nausea in the conventional treatment group (8% more).
The authors of the study indicate that the results might be not generalized for less dependent smokers or the oldest electronic cigarettes.
