    Default Electronic cigarettes (e-cigarettes) may be more effective at helping smokers quit

    Electronic cigarettes (e-cigarettes) may be more effective at helping smokers quit than nicotine patches or gum, TIME magazine reported Feb. 10.

    The researchers, led by Michael Siegel, M.D., sent surveys to 5,000 first-time buyers of e-cigarettes over two weeks in 2009. The response rate was low (4.5 percent), or 222, according to a summary published by the Boston University School of Public Health. Respondents were primarily older males who had tried to quit smoking many times in the past.

    Nearly 67 percent of the respondents reported that they had cut down on cigarettes six months after beginning use of e-cigarettes, and 34.3 percent said they were not using e-cigarettes or other cessation aids that contained nicotine. Other research has shown that around 12 to 18 percent of people who used nicotine patches and nicotine gum report abstinence at six months -- nearly half the rate of those who used e-cigarettes in this survey.

    "This study suggests that electronic cigarettes are helping thousands of ex-smokers remain off cigarettes," Siegel said.

    The authors of the study acknowledged that the study's conclusions were limited by the low response rate, pointing out that smokers who had quit or cut down on smoking might be more likely to respond. However, they said it was the best evidence to date on the effectiveness of e-cigarettes, and that the devices "hold promise as a smoking-cessation method and that they are worthy of further study using more rigorous research designs."

    TIME said that at least one earlier study had concluded that e-cigarettes were ineffective at helping smokers quit. Several states are considering prohibiting their use.

    "Banning this product would invariably result in many ex-smokers returning to cigarette smoking," Siegel said. "Removing electronic cigarettes from the market would substantially harm the public's health."

    Meanwhile, a second study of e-cigarettes from the Johns Hopkins Bloomberg School of Public Health reviewed internet searches for smoking alternatives between January 2008 and September 2010 and found that e-cigarettes had become far more popular than other options, at least in the United States and the U.K.

    "Neither of these two studies provides scientific evidence that e-cigarettes are effective in helping people to quit," said professor John Pierce of the Moores Cancer Center at the University of California, San Diego. "It's not clear to me that e-cigarettes aren't harmful in some way. It's not clear to the FDA, either."

    Default Re: Electronic cigarettes (e-cigarettes) may be more effective at helping smokers quit

    Electronic cigarettes typically use a rechargeable battery-operated heating element to vaporize the nicotine in a replaceable cartridge. Nicotine is usually dissolved in propylene glycol, a clear and colorless liquid that is commonly found in inhalers, cough medicines and other products.Some e-cigarettes are made to look like real cigarettes, cigars or pipes. Others look like pens or USB memory devices.
