The U.S. Food and Drug Administration is considering a ban on flavored e-cigarettes in response to an “epidemic” of young people using e-cigarettes, the agency’s leader said today.

In a speech at FDA headquarters, Commissioner Scott Gottlieb said the agency would also revisit its compliance policy that extended the dates for manufacturers of flavored e-cigarettes to submit applications for pre-market approval.

Gottlieb announced a number of steps the agency planned to take as part of a broader crackdown on the sale and marketing of e-cigarettes to kids. The agency issued 12 warning letters to companies that it says have deceptive marketing labels on e-liquids. We cannot allow a whole new generation to become addicted to nicotine.”
