Background
This systematic review aims to identify the benefts and harms of electronic cigarettes (e-cigarettes) as a smoking cessation aid in adults (aged≥18 years) and to inform the development of the Canadian Task Force on Preventive Health Care’s (CTFPHC) clinical practice guidelines on e-cigarettes.
Methods
We searched Ovid MEDLINE®, Ovid MEDLINE® Epub Ahead of Print, In-Process & Other Non-Indexed Cita tions, PsycINFO, Embase Classic+Embase, and the Cochrane Library on Wiley. Searches were conducted from January 2016 to July 2019 and updated on 24 September 2020 and 25 January 2024. Two reviewers independently performed title-abstract and full-text screening according to the pre-determined inclusion criteria. Data extraction, quality assess ments, and the application of Grading of Recommendations Assessment, Development and Evaluation (GRADE) were performed by one independent reviewer and verifed by another.
Results
We identifed 18 studies on 17 randomized controlled trials that compared e-cigarettes with nicotine to e-cigarettes without nicotine and e-cigarettes (with or without nicotine) to other interventions (i.e., no interven tion, waitlist, standard/usual care, quit advice, or behavioral support). Considering the benefts of e-cigarettes in terms of smoking abstinence and smoking frequency reduction, 14 studies showed small or moderate benefts of e-ciga rettes with or without nicotine compared to other interventions; although, with low, very low or moderate evidence certainty. With a focus on e-cigarettes with nicotine specifcally, 12 studies showed benefts in terms of smoking abstinence when compared with usual care or non-nicotine e-cigarettes. In terms of harms following nicotine or non nicotine e-cigarette use, 15 studies reported mild adverse events with little to no diference between groups and low to very low evidence certainty.
Conclusion
The evidence synthesis on the e-cigarette’s efectiveness shows data surrounding benefts having low to moderate evidence certainty for some comparisons and very low certainty for others, indicating that e-cigarettes may or probably increase smoking cessation, whereas, for harms, there is low to very low evidence certainty. Since the duration for outcome measurement varied among diferent studies, it may not be long-term enough for Adverse Events (AEs) to emerge, and there is a need for more research to understand the long-term benefts and potential harms of e-cigarettes.
