Study: E-cigarettes don't help smokers quit
Electronic cigarettes are widely marketed as a way to help smokers quit traditional cigarettes, but a large new analysis finds they may actually have the opposite effect.
In fact, the report, published online today in The Lancet Respiratory Medicine, found that adult smokers who use e-cigarettes are actually 28 percent less likely to stop smoking cigarettes.
The question has been studied numerous times in the past, yielding sometimes conflicting results. But the new study -- systematic review and meta-analysis of published data -- is the largest to date.
