Illinois started a 15% e-cigarette tax July 1.

On a 30-milliliter bottle of e-cigarette fluid costing $19.99, Wisconsin’s new law will levy a $1.50 tax. Evers’ proposal would have yielded a tax of $14.19.

Wisconsin’s tax on regular cigarettes of $2.52 per pack is 12th-highest among states, the report said.

E-cigarettes and other vaping devices vaporize liquid nicotine. They don’t carry the harmful risks of combustible tobacco, as cigarettes do, but can expose users and others to heavy metals and chemicals, health officials say.

E-cigarettes are touted as a way to help adult smokers quit cigarettes. But health authorities are concerned about their growing use among youths, saying it can lead to cigarette smoking.

Some 20% of Wisconsin high school students said last year they were using electronic cigarettes, up from 8% in 2014 — an “alarming” increase that led the state Department of Health Services to issue an advisory in January.

The Wisconsin Public Health Association said the 5-cent tax is “nowhere near parity with taxation on cigarettes,” as the 71% tax was meant to achieve.
