Demystifying electronic cigarette use in pregnancy.

Electronic cigarettes (ECIGs) are a relatively recent phenomenon, serving a dual role as a potential smoking-cessation tool and an alternative nicotine-delivery system. Although research has addressed the use of ECIGs in general populations, its use during pregnancy has not been studied. The authors seek to inform readers about the current evidence base regarding ECIG use in general and to describe a patient who began using ECIGs regularly during pregnancy as a smoking cessation tool. Continued research is needed to inform patients about the potential risks and benefits of ECIG use, including during pregnancy.
