Abstract

E-cigarettes have grown in popularity since their inception in 2004. Although initially introduced for smoking cessation, with its enticing flavors, designs, and marketing as a healthier alternative to conventional cigarettes, there are growing concerns regarding its true efficacy for its designed purpose, in addition to its overall safety. In this review, current data on the effect on health system’s (i.e. cardiovascular, respiratory, stroke, cancer), as well as how flavorings and socioeconomics impact the risks and/or benefits of e-cigarette usage. Generally, studies have demonstrated that there is a relatively reduction in harm of e-cigarettes when compared to conventional cigarettes; however, more longitudinal studies are needed given reported increases in inflammatory markers, oxidative stress, and DNA damage. In addition to concerns over potential harm to users, regulating flavorings, heating elements, voltage, coil resistance, and pricing may improve user safety. Regardless, more studies are needed to truly access the safety of e-cigarettes for use as an effective smoking cessation approach.
