INDIANAPOLIS (AP) - Indiana would impose a 20 percent tax on the liquids used in electronic cigarettes under a proposal endorsed by a legislative committee.

The Senate Appropriations Committee voted Thursday in support of the bill. The vote came after the committee adopted the tax on the price of the vaping liquid, rather than a 4 cents per-milliliter tax that was backed by the House in February. Republican Sen. Travis Holdman of Markle says the 20 percent tax comes out similar to the tax on a pack of cigarettes and will be easier to calculate than a tax based on the amount of vaping liquid sold.

Supporters argue the tax could discourage vaping.

The full Senate could vote on the proposal next week.
