Published this week in the British Medical Journal, the study titled 'E-cigarette use and associated changes in population smoking cessation: evidence from U.S. current population surveys' examined more than 160,000 respondents of different smoking statuses (never smoked through to heavy smokers), including 2136 recent quitters, from five different population studies.

Even if they're "healthier" than regular cigarettes, e-cigs still aren't great: cancer-causing chemicals have been found in e-cigs, and vaping might still increase your risk of heart disease.

E-cigarettes have been sold in the US since 2007.

More Americans stop smoking, and it may all be thanks to e-cigarettes.

For the study, published today in the journal BMJ, researchers analyzed survey data from over 160,000 people spanning nearly 15 years.

The study called E-cigarette use and associated changes in population smoking cessation: evidence from United States current population surveys, was carried out by researchers from the Department of Family Medicine and Public Health, and Moores Cancer Center, both at the University of California.

Pharmacotherapy has been shown to help some people to quit smoking, but not at the same rate as e-cigs.

Mr Hajek said: 'It's absolutely clear that e-cigarettes help smokers replace cigarettes'.

E-cigarettes are less addictive as vapers are not as dependent on their habit as traditional smokers, research revealed last month.

The BMJ study, titled "E-cigarette use and associated changes in population smoking cessation: evidence from USA current population surveys" was undertaken to find whether the dramatic increase in vaping between 2010-2014 had any connection with an overall drop in smoking in the US. While the sale of e-cigarettes is banned in Australia, U.K provides a license to e-cigarettes as a smoking cessation aid. The authors write that things like national ad campaigns against smoking and a tobacco tax probably helped, too.

How safe are e-cigarettes?

"This study suggests that we should be receptive to the kind of approach that health authorities in England have taken, encouraging smokers who can not quit otherwise to try e-cigarettes", Warner said.

Regulation policies on e- cigarettes differ from country to country. Food and Drug Administration finalized rules to regulate e-cigarettes. Most devices heat a liquid nicotine solution into vapour and were promoted to smokers as a less unsafe alternative since they don't contain all the chemicals, tar or odour of regular cigarettes.

Whilst this report used the largest representative sample of smokers and e-cigarette users available to date, it still has some weaknesses.
