(AP) — Nebraska minors could soon be banned from using e-cigarettes.

Lawmakers voted 28-0 Tuesday on a measure that would prohibit minors from using the product, and prevent stores from selling them to anyone under 18.

Sen. Russ Karpisek of Wilber, who introduced the legislation, says there hasn’t been enough study to know if e-cigarettes are safe.

Electronic cigarettes are battery-powered devices that give users a puff of vapor, typically containing nicotine and sometimes flavorings such as fruit or mint. Users can vary the amount of nicotine.

Sen. Colby Coash of Lincoln says the devices should be available to help minors quit smoking.

The National Conference of State Legislatures says that at least 27 states have prohibited the sale of e-cigarettes to minors.
