SALEM — The Oregon Legislature is beginning to look at whether to tax electronic cigarettes.

State Department of Revenue officials told House and Senate committees on Tuesday that the state has no taxes on electronic cigarettes, which are battery-powered devices that contain nicotine but not tobacco. E-cigarettes are growing in popularity as alternatives to traditional cigarettes.

Democratic Rep. Phil Barnhart of Eugene, the chairman of the House Revenue Committee, said the state should look at taxing e-cigarettes because they contain nicotine, an addictive substance.

"I'm always interested in keeping drugs away from kids and generating some money," Barnhart said.

Others said lawmakers should tread carefully while more data are collected about e-cigarettes. "If there's a thought that someday we might tax these things as we do cigarettes, it would seem odd that we would disincentivize people from moving away from something that's dangerous to something that's less so," said Rep. Cliff Bentz, R-Ontario.

E-cigarettes heat a liquid nicotine solution and create vapor that users inhale. Because they don't contain tobacco, they don't fall under tobacco taxation laws in 49 states, including Oregon.

Even if the state decides to tax e-cigarettes, it's far from clear how it would go about assessing the charge, the Revenue Department's Deanna Mack told lawmakers. Cigarettes are taxed with a stamp on each pack, and other tobacco products are assessed based on the wholesale price or the weight of the product.

Nu Mark LLC, which is developing e-cigarettes for Altria Group Inc., the parent company of Philip Morris, urged caution. "Nu Mark believes that governments should refrain at this point from taxing new nicotine-containing products altogether until there is a better understanding of where the consumers ultimately land with this emerging category."
