During 34 years of smoking, Carolyn Smeaton has tried countless ways to reduce her three-pack-a-day habit, including a nicotine patch, nicotine gum and a prescription drug. But stop-smoking aids always failed her.
Then, having watched a TV infomercial at her home here, Ms. Smeaton tried an electronic cigarette, which claimed to be a less dangerous way to feed her addiction. The battery-powered device she bought online delivered an odorless dose of nicotine and flavoring without cigarette tar or additives, and produced a vapor mist nearly identical in appearance to tobacco smoke…
For $100 to $150 or so, a user can buy a starter kit including a battery-powered cigarette and replaceable cartridges that typically contain nicotine (though cartridges can be bought without it), flavoring and propylene glycol, a liquid whose vaporizing produces the smokelike mist.
Propylene glycol is used in antifreeze, and also to create artificial smoke or fog in theatrical productions. The F.D.A. has classified it as an additive that is “generally recognized as safe” for use in food. But when asked whether inhaling it was safe, Dr. Richard D. Hurt, director of the Nicotine Dependence Center at the Mayo Clinic, said, “I don’t think so, but I’m not sure anyone knows for sure.”
Of the e-cigarettes themselves, Dr. Hurt added: “We basically don’t know anything about them. They’ve never been tested for safety or efficacy to help people stop smoking.”
