Using electronic cigarettes - or 'vaping' - can more than double the chances of smokers kicking the habit, a new study has found.

Researchers from the UK and New Zealand studied how the habits of 662 traditional cigarette smokers changed when using e-cigarettes, which work by vaporising a solution which contains nicotine.

Across two randomised trials, they found that around nine per cent were able to quit completely within a year - more than double those using nicotine-free placebos.

And even among those who did not quit, the results showed an encouraging trend towards cutting down.

A total of 36 per cent of those who did not quit reduced the number of cigarettes they smoked by half, along with 28 per cent of the placebo group.

Researchers also found the effectiveness of e-cigarettes was comparable to that of nicotine patches.

Prof Peter Hajek, one of the Cochrane Library review's authors, said he felt authorities were "wary" of e-cigarettes, which may have hampered research efforts.

He welcomed the results as encouraging, and while he said more research was needed, he added he would support their use as a tool for smokers trying to quit based on what had been found.

Deborah Arnott, chief executive of charity Action on Smoking and Health, said she hoped the review would encourage more research, which could potentially save thousands of lives.

A spokeswoman for the Department of Health said while they were aware of the potential benefits of e-cigarettes, officials wanted to ensure they were safe and properly regulated.
