Study: Teens who smoke e-cigarettes at higher risk of smoking

BURLINGTON, Vt. (WCAX) A new study out Tuesday on vaping says teenagers who smoke e-cigarettes may be at a higher risk of switching to traditional smoking.

Whether e-cigs do or don't lead to regular smoking has been highly-debated for years. The national public health panel said vaping may prompt teens to try cigarettes and get hooked. But it also said no significant linkage between vaping and cigarette addiction has been established.

St. Michael's College psychology professor Ari Kirshenbaum studies e-cigarette use and says there are a lot of other issues at play for those who chose to smoke. "Psychological, socio-demographic issues that can contribute to e-cigarette use in adolescents that also contribute to combustible tobacco use in that same group," he said.

The study did say e-cigarette use does help regular smokers quit. And it said that e-cigarettes are safer than regular cigarettes, but it stopped short of calling them safe.= because long-term studies on health impacts don't exist yet.
