In Maryland, opponents of a bill to ban smoking electronic cigarettes in public places lined up in Annapolis to speak against the measure.
Rick Mulder of Easton was one of many standing in the hallway "vaping" outside of the House Economic Matters Committee room. He started smoking e-cigarettes about five years ago, and enjoys them so much he'll never return to traditional cigarettes. Mulder doesn't think the vapor e-cigarettes produce is harmful to others like second-hand smoke.
"The ingredients are propylene glycol, vegetable glycerin, food flavoring, and nicotine. Nicotine in itself isn't the harmful stuff. Tomatoes have nicotine in them, eggplants have nicotine in them. So, you're looking at four ingredients that all of which are FDA approved," he says.
But Montgomery County Democratic Del. Aruna Miller isn't buying that e-cigarettes are harmless to those not smoking and breathing in the vapor. Her bill would ban them in the same places that traditional cigarettes are currently outlawed, like bars and restaurants.
"The tobacco industry when cigarettes first came out they also said there were no problems with second hand smoke. Now... we have the e-cigarette industry claiming the same thing. There isn't enough science out there," she says.
Attempts to ban the devices are moving just as quickly as the popularity of them. This week, the Los Angeles City Council was the latest body to approve a ban.
