Abstract

There is abundant evidence that e-cigarettes can help some individuals to quit smoking and so they should be more widely recommended as smoking cessation aids.

Electronic- or e-cigarettes are hand-held battery-operated devices that heat a liquid, containing propylene glycol and/or glycerin, flavoring compounds, and typically nicotine, to produce an aerosol that users inhale, or vape. The consequences of nicotine vaping are controversial, with two perspectives dominating discussion: the risks of vaping for young people; and the potential of vaping to increase smoking cessation among adults.1 This commentary focuses on the latter.

First, the paper reviews evidence that vaping increases smoking cessation. Then it examines the health consequences of e-cigarettes. Next, differences across countries in how e-cigarettes are regulated are reviewed. The paper concludes with what the evidence implies for clinical care, taking into account what medical and governmental authorities in various countries consider the appropriate role of e-cigarettes in smoking cessation.
