Last weekend, the Vape Summit hit Las Vegas, complete with industry business folks, a poker tournament, the “world’s largest e-juice sample bar” and lots of people using a word that sounds uncomfortably similar to “rape.”

E-cigarettes have seen such growth in the U.S. that the FDA is considering new regulations, and individual cities are enacting their own policies on the battery-powered devices that vaporize flavored, liquid nicotine. Las Vegas has yet to take any official action, but that doesn’t mean you can vape wherever you please. We got on the phone to find out where you can and cannot puff:

DB Brasserie At Daniel Boulud’s new Venetian restaurant you can order escargots spätzle and a duo of beef, but you can’t chase those red wine-braised short ribs with liquid nicotine. It’s a no-vaping zone.

Las Vegas Athletic Club Want to puff an e-cig on the elliptical? Nyet! says the LVAC front desk. Actually, they just said that smoking is “not allowed” on property.

Bass Pro Shops A customer service rep says they haven’t had any complaints about customers vaping inside the outdoor outlet, so for now it’s a go, “with discretion.”

Clark County public schools After seeing a rise in teens experimenting with e-cigs, the school board banned vaping on its campuses and grounds in April, including use by students, teachers and staff.
