As the popularity of e-cigarettes rises, so does the need for public places for those  those who inhale vapor instead of smoke.

The world’s first e-cigarette lounge opened last week at London’s Heathrow Airport. Previously, e-smokers were subject to the same restrictions as traditional smokers: They had to stand outside the terminal to get their nicotine fix.

E-cigarettes produce water vapor rather than smoke.

The 323-square foot lounge was opened by Gamucci, an electronic cigarette manufacturer.

“Electronic cigarettes are subject to the same restrictions as standard cigarettes and therefore cannot be used inside terminal buildings, except in the designated e-cigarette lounge in Terminal 4,” the airport’s web site states. “They can be carried on your person, but please check with your airline on whether they are allowed on board the aircraft.”

Most travelers appear to be supportive of the lounge. A survey by Skyscanner.net found 57 percent of people would not object to other airports following Heathrow’s lead. Not surprisingly,  more smokers than non-smokers were in favor of the lounge. Still, half of all non-smokers surveyed were supportive of more lounges. (click for more)
