LONDON (Reuters) – Electronic cigarettes are almost twice as effective at helping smokers quit smoking as nicotine substitutes such as patches, sugar pills and chewing gum, according to a new study.
A study of 900 smokers revealed that 18% of electronic cigarette users became nonsmokers within one year, compared to 9.9% who tried to quit smoking using other means.
"This is great news for cigarette smokers who want to quit smoking," said Richard Mitch of the University of Michigan. This is a convincing proof. "Tobacco is not used in electronic cigarettes, but it contains liquids containing nicotine, inhaled in the form of smoke, and several large tobacco companies sell several electronic cigarettes.
Many health experts consider the use of electronic cigarettes as an effective way to help smokers quit smoking. But scientists are divided on their potential benefits to public health.
Independent experts said the latest study, funded by the British National Institute of Health Research and led by researchers at Queen Mary University in London, was sound and well conducted.
Some research has already suggested that e-cigarettes may help smokers to reduce or completely stop smoking, but other studies have raised concerns about their use in adolescents.
The new study, published in the New England Journal of Medicine, revealed a stronger impact on e-cigarettes than previous studies. The researchers said that this could be due to the participation of smokers in search of help, to provide them with direct support and to allow users of electronic cigarettes to choose liquids.
