E-cigarettes more effective than nicotine replacement therapies, finds major UK clinical trial

E-cigarettes are almost twice as effective as nicotine replacement treatments, such as patches and gum, at helping smokers to quit, according to a clinical trial led by Queen Mary University of London.

The multi-centre trial, which involved almost 900 smokers who also received additional behavioural support, found that 18.0 per cent of e-cigarette users were smoke-free after a year, compared to 9.9 per cent of participants who were using other nicotine replacement therapies.

Lead researcher Professor Peter Hajek, Director of the Health and Lifestyle Research Unit at Queen Mary's Wolfson Institute of Preventive Medicinesaid: “This is the first trial to test the efficacy of modern e-cigarettes in helping smokers quit. E-cigarettes were almost twice as effective as the ’gold standard’ combination of nicotine replacement products.

“Although a large number of smokers report that they have quit smoking successfully with the help of e-cigarettes, health professionals have been reluctant to recommend their use because of the lack of clear evidence from randomised controlled trials. This is now likely to change.” More.
