A British study has found e-cigarettes twice as effective as helping smokers give up tobacco than nicotine patches or gum.
The study, published in the New England Journal of Medicine, found that 18% of e-cigarette users had kicked the habit after the trial period, compared to 9.9% of those using other nicotine replacements (patches, lozenges, chewing gum, inhalers and sprays).
What’s more, e-cigarette users experienced less severe urges to smoke, as well as less irritability and restlessness and better concentration one to four weeks after giving up tobacco.
Still, e-cigarettes are not without risk. The nicotine in them is highly addictive and several studies have shown they contain a wide range of potentially toxic substances, the long-term effects of which have yet to be quantified.
