The Buzz | Teens’ e-cigarette use linked with later smoking

A study at 10 Los Angeles high schools links e-cigarettes with later tobacco use.
University of Southern California researchers found that 14-year-olds who’d ever tried e-cigarettes were more likely than others to later try other tobacco products.
The study doesn’t prove that electronic cigarettes are a “gateway drug” but some doctors say it bolsters arguments that the devices need to be strictly regulated. The government-funded study was published in yesterday’s Journal of the American Medical Association.
National data show e-cigarettes have become more popular among teens than regular cigarettes. The Food and Drug Administration has proposed rules that would ban the sale of electronic cigarettes to minors.
