July 28 (UPI) -- A new study suggests e-cigarettes are effective as an aid to quit smoking and are linked to an increase in smoking cessation rates.
The study, published July 26 in The BMJ, included 160,000 participants from a series of large population surveys from 2010-2011 to 2014-2015, when e-cigarette use rose from more than 1 percent to 30 percent, respectively.
