Electronic Cigarettes Potential Risks and Benefits

As the popularity of the electronic cigarette (e-cigarette) has grown since its introduction in 2007, so has the controversy related to this new nicotine-delivery device. Manufacturers have stated that the aerosols and vapor in e-cigarettes are "tar free" and lack carcinogens associated with traditional cigarettes, but the e-cigarette's true safety profile and potential role as a smoking cessation tool are yet to be determined. A study by the FDA found potentially harmful chemicals in some tested products, including diethylene glycol and tobacco-specific nitrosamines, as well as the presence of nicotine in products advertised as nicotine-free. It is anticipated that additional studies on safety and efficacy of these devices will provide pharmacists definitive information on how to counsel patients about using such products and their potential role in smoking cessation.
