University of Michigan finds vaping could lead to real cigarette smoking

(CP) - A new U-S study suggests smoking e-cigarettes, or ``vaping'', could be a gateway to real cigarette smoking.

Researchers at the University of Michigan found that high-school seniors who'd never previously smoked had a four times greater likelihood of smoking regular cigarettes if they had tried an e-cigarette.

The study is in the journal, Tobacco Control.
