Introduction: E-cigarettes (EC) are devices that heat liquid into an aerosol that user inhales. Youth are using EC at increasing and alarming rates. The tobacco industry aggressively markets EC to youth, glamorizing EC use in advertisements, and offering EC in candy flavors such as bubble gum and gummy bears. The liquid usually in EC has nicotine and other additives which is addictive. Aim: The purpose of this study was to systematically review the role of e-cigarettes in smoking cessation. Materials and Methods: A literature review was performed; PubMed, PubMed Central and Cochrane Library, Embase, and Google Scholar were searched from 1970 to December 2017 to identify appropriate studies. Results: Out of the total 817 titles appeared, 17 articles fulfilled the criteria and were selected for the review. Two articles which were hand searched and one article which was through E-mail was also included in this review. EC have a direct impact on smokers and efficiency in quitting smoking was assessed very low. Majority of the study found that EC could increase the risk of smokers developing nicotine dependence and thus evidence on smoking reduction was found very low. Conclusions: There are relatively a few studies evaluating the role of EC in smoking cessation. EC products are marketed in a wide variety of channels that have broad reach among youth and young adults, including magazines, television, radio, and the Internet. More randomized controlled trials and longitudinal studies are needed to further clarify the role of EC in smoking cessation.
