Sen. Richard Blumenthal, D-Conn., wants to raise the minimum age to buy e-cigarettes from 18 to 21 and also ban flavors in an attempt to curb rampant use among minors.

The Food and Drug Administration has already floated banning sales of e-cigarettes in convenience stores. Major e-cigarette manufacturer Juul Labs announced Tuesday that it will halt sales of its flavored e-cigarette products to convenience stores and vape shops.
