Electronic Cigarettes—A Narrative Review for Clinicians

Published:February 28, 2015DOI:https://doi.org/10.1016/j.amjmed.2015.01.033

      Abstract

      Electronic cigarettes (e-cigarettes) were introduced into the US market in 2007 and have quickly become a popular source of nicotine for many patients. They are designed to simulate smoking by heating a nicotine-containing solution producing an aerosol that the user inhales. The short- and long-term effects of e-cigarette use are still unclear, but their use is increasing. Some acute effects of e-cigarettes on heart rate, blood pressure, and airway resistance are reported. Although there are some reports of improved cessation in a subset of users, there are also studies reporting decreased cessation in dual users of regular and e-cigarettes. Additionally, there is no current regulation of these devices, and this allows virtually anyone with a form of online payment to obtain them.
