Down the street from the State Capitol, in St. Paul's Midway neighborhood, Vape Pro's owner Troy Decorsey puffed banana bread-flavored nicotine from his e-cigarette device, which he said helped him quit smoking after 25 years.
"You prove that secondhand vapor is harmful, and I will shut my store down," he said. "I will leave right now."
In a crowded hearing room at the Capitol, some legislators said Wednesday that consumers can't wait decades for proof, the way they did with tobacco.
"This is the Wild West," Rep. Laurie Halverson, DFL-Eagan, told a panel of lawmakers looking at restricting e-cigarettes. "We just don't know and the consumer doesn't know. The consumer is being told they're harmless, but the fact is the consumer doesn't know because we haven't regulated it."
Minnesota's debate is part of a national battle over e-cigarettes, with some of the nation's largest cities adding "No Vaping" to signs that already say "No Smoking." In Minnesota, where 80 percent of the state's 200 e-cigarette retailers have popped up in the past year, the Legislature is eyeing the idea of regulating them like regular tobacco, including banning their use indoors and in public places. But the measure is being met with resistance from the industry, which says the products are far from being comparable to cigarettes.
E-cigarettes can contain nicotine laced with various flavors, or can be nicotine-free. There is no tobacco, so the devices emit a vapor rather than tobacco smoke. Experts are divided over whether the vapors themselves contain chemicals that are dangerous to inhale.
"Here's the deal," Decorsey said. "As soon as they see 'smoke,' they assume the worst. Because they don't smoke, they assume the worst. The problem is that they're not knowledgeable about it. Nobody is."
Opponents call electronic cigarettes the next public health menace, geared toward luring kids into nicotine addiction with candy-sweet flavors like "cola," "milk chocolate" and "bubble gum."
