E-cigarettes and nicotine abstinence
Hanewinkel R, Niederberger K, Pedersen A, et al. E-cigarettes and nicotine abstinence: a meta-analysis of randomized controlled trials. Eur Respir Rev. 2022 Mar 23;31(163):210215. “We included four RCTs representing 1598 adult participants…. Compared to NRT, e-cigarette use was associated with lower nicotine abstinence rates at the longest follow-up (risk ratio 0.50 (95% CI 0.32-0.77)). Among successful cigarette quitters, the risk of allocated product use by the end of the observational time was higher for e-cigarette users compared to NRT (risk ratio 8.94 (95% CI 3.98-20.07)).”
