US adults that vape daily are more likely to quit smoking than those who have never used an e-cig, according to a study into cigarette-users who have smoked for the last five years. The study, carried out by researchers from Columbia University's Mailman School of Public Health and the Rutgers School of Public Health, has found that over 50 per cent of daily e-cig users have quit smoking in the last five years, compared to just 28 per cent who hadn’t vaped.

Hailed as the first longitudinal study into the cessation success among e-cig users at national level, the study has been published online at Addictive Behaviors. The study has found that those using e-cigarettes daily had the highest rate of quitting smoking, three times more likely than non-vapers. The news is made all the more emphatic by recent studies that showed e-cigarettes are less addictive than regular cigarettes.

Daniel Giovenco, PhD, lead author of the study and assistant professor of Socio-medical Sciences at the Mailman School of Public Health, said: "While questions regarding the efficacy of e-cigarettes for smoking cessation remain, our findings suggest that frequent e-cigarette use may play an important role in cessation or relapse prevention for some smokers.”

Giovenco adds, "The FDA recently delayed rules that would have limited e-cigarettes on the market. This indicates that public health officials may be receptive to innovative and lower-risk nicotine products. Uncovering patterns of use at the population level is a critical first step in determining if they may present any benefits to public health."
