Outgoing Food and Drug Administration Commissioner Scott Gottlieb warned Friday that pod-based e-cigarettes could be banned altogether if rates of teen vaping continue to rise.

“If we can’t start reversing these trends this year and don’t see the rates start to come down we’ll have to take more dramatic actions,” Gottlieb said on Fox News. “We’ll have to look at the pod-based cigarettes as a category and potentially take them off the market.”
