ST. PAUL, Minn. (AP) — An attempt to treat electronic cigarettes like regular smokes has stalled in the Minnesota Legislature.

A House-Senate conference committee on Tuesday decided against adding e-cigarette use to the indoor air laws that would have prohibited their use in most public spaces. The Senate had passed the toughest measure, but House members say they lacked sufficient votes to move ahead.

Lawmakers are tackling the emerging devices that deliver nicotine and emit a vapor. They are primed to restrict sales so minors can't access them and they can't be used on school grounds. The liquids would also have to be sold in tamper-proof bottles that make it hard for young children to open.

Public health advocates wanted to outlaw their use in bars, restaurants and other venues.
