Electronic cigarettes (e-cigarettes) present a novel method for nicotine delivery that is reportedly advantageous when compared to traditional cigarette usage. Manufacturers and consumers claim reduced chemical exposure, decreased symptom profiles, and efficacy in smoking reduction and cessation greater than conventional nicotine replacement therapies (NRT). However these products present new challenges and concerns to legislators, clinicians, and public health advocates. Questions of authority in state and federal legislation, establishing product quality control, assessing long-term studies on e-cigarettes and quantifying usefulness in harm reduction represent only a portion of the many unanswered topics being discussed. The purpose of this article is to assess the literature on e-cigarettes and establish perceptions and attitudes on this controversial subject.
