Replacement of tobacco for electronic cigarettes is an effective method to prevent smoking, according to an investigation led by the Queen Mary University in London (United Kingdom).
The results of the clinical trial, 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 left, while in those who used conventional methods, such as patches or nicotine, only 10% achieved this.

"Although many smokers have confirmed that they have successfully quit smoking with the help of electronic cigarettes, health professionals do not want to recommend use for lack of clear evidence of randomized clinical trials. It's likely to change from now on, "said Peter Hike, a researcher at Queen Mary University in London, who led the research.
In the clinical trial 886 smokers participated who went to health centers in search of help to give up. Doctors distributed them randomly in two groups. In the first group, they were replaced with nicotine at their own choice, such as patches, chewing gum, tablets or inhalers, which should last up to three months. In the second group, smokers received an electronic cigarette pack with accessories and were encouraged to buy the flavors they liked most. Additionally, all participants received support sessions with healthcare staff for four weeks.

A year later, 10% of smokers who were treated with conventional nicotine substitutes, stopped smoking. Among those who received electronic cigarettes, they received almost double, 18%.
Among the participants who failed to give up, among those who used electronic cigarettes, they received moreEducate the amount of tobacco who smoked in half. Electronic cigarettes have also reduced the production of cough and phlegm more than other nicotine substitutes.

On the other hand, doctors noticed more irritation of the throat in the group that used electronic cigarettes (14% more) and more nausea in the group of conventional treatments (8% more).
The authors of the research indicate that the results could be can not be generalized to less dependent smokers or the oldest electronic cigarette.
In an editorial published in the same issue of the New England Journal of Medicine, researchers at the Boston Medical School (USA) recommend care for doctors when prescribing electronic cigarettes, waiting for new studies to prove their effectiveness and security.
