E-cigarettes are increasingly being examined for their role in smoking cessation and reduction. A systematic review and meta-analysis evaluates how nicotine-containing e-cigarettes influence quitting outcomes. The findings suggest a positive association between e-cigarette use and both smoking abstinence and reduced cigarette consumption over time. However, results vary depending on the type of comparison, with some analyses showing no significant difference when compared to traditional nicotine replacement therapies. Overall, the evidence points to a potential role for e-cigarettes in supporting smoking cessation, while highlighting the need for further long-term research.
