Tracking the conflicting claims about e-cigarette safety

A look at the numbers shows that vaping is catching on as quickly as smoking did in the 1950s. In just two years, the percentage of smokers who have tried e-cigarettes, which vaporize a liquid solution rather than burn tobacco, jumped from 2% in 2010 to 30% in 2012.
Fueling that trend are claims that e-cigs are a healthier way for people to use nicotine and that they can help smokers kick the habit. The latest report from the U.K. found that the devices were 60% more likely than nicotine patches or gum to help smokers give up cigarettes.
That seems like good news, but as with most data on e-cigs, which are not yet regulated by the Food and Drug Administration, those numbers may be a smokescreen.
