(AP) — Nebraska lawmakers are set to discuss a possible ban on the sale of e-cigarettes to minors.

The so-called e-cigarettes heat liquid nicotine into a flavored, smokeless vapor. They’re commonly used by smokers who are trying to quit, but their growing popularity among teenagers has caught the attention of Nebraska lawmakers, who have scheduled a hearing on Friday.

The Legislature’s General Affairs Committee will discuss the issue during a hearing that starts at 1:30 p.m. at the Capitol. The hearing could lead to legislation next year that would ban their sale to minors once lawmakers.
