Objectives: Little is known regarding the effectiveness of electronic cigarettes (e-cigarettes) as therapy to aid in smoking cessation. Many hypothesize that e-cigarettes are equally as effective or more effective than alternate smoking cessation therapies. The purpose of this review was to examine the evidence on effectiveness of e-cigarettes on smoking cessation and quitting behavior as compared to other smoking cessation therapies, or no therapy at all.

Methods: Searches were done in PubMed utilizing the terms “electronic cigarettes” and “smoking cessation” [MeSH terms]. In PubMed, the following filters limits were used: published in the last 5 years, human species, English language, and adult (19+ years old).

Results: Studies by Biener and Hargraves, Brown et al, and Bullen et al, demonstrated a positive correlation of electronic cigarettes with smoking cessation. However, study by Bullen et al was not statistically significant. Study by Al-Delaimy et al revealed a negative correlation of electronic cigarette use on smoking cessation.

Conclusion: These studies demonstrate the inconsistencies that compose the existing research on electronic cigarettes and their role on smoking cessation. Additional research remains a vital factor in determining the effect of e-cigarettes on smoking cessation, as well as an investigation of the safety of these devices.
