How old do you have to be to buy e-cigarettes in the United States? I’m 19 years old!

You must be 21 years old to buy e-cigarettes (vapes) in the United States.

This is set by federal law under the Tobacco 21 (T21) legislation, signed on December 20, 2019. It raised the minimum sales age for all tobacco products—including e-cigarettes, e-liquids, and nicotine delivery systems—from 18 to 21 nationwide. The rule applies to all retailers with no exceptions (including for military personnel).
