Efficacy of smokeless tobacco for smoking cessation

Stjepanović D, Phartiyal P, Leung J, et al. Efficacy of smokeless tobacco for smoking cessation: a systematic review and meta-analysis. Tobacco Control. Online First. 23 Feb 2022. Three databases were searched for studies that assessed the effectiveness of snus in promoting smoking abstinence. A total of 28 studies were reviewed (5 randomized controlled trials (RCTs), 7 longitudinal, and 16 cross-sectional studies). Because of mixed results and a high likelihood of bias in many studies, authors conclude that “There is weak evidence for the use of snus for smoking cessation. Better RCTs and longitudinal studies are needed; meanwhile, existing cessation aids may be better placed than snus to promote abstinence.” https://tobaccocontrol.bmj.com/content/early/2022/02/23/tobaccocontrol-2021-057019
