An Overview of the Effectiveness of Smoking Cessation Interventions: A Critical Analysis of Evidence from Randomized Controlled Trials and Meta -Analyses

Abstract

This literature review provides a comprehensive analysis of smoking cessation interventions, focusing on their effectiveness as demonstrated in randomized controlled trials (RCTs) and meta-analyses. Smoking remains a major public health concern globally, with significant implications for morbidity, mortality, and healthcare costs. Numerous interventions have been developed to aid individuals in quitting smoking, including pharmacotherapy, behavioral counseling, and alternative therapies. This review critically evaluates the evidence from RCTs and meta-analyses to assess the effectiveness of these interventions in promoting smoking cessation and reducing tobacco-related harm. The findings highlight key factors influencing intervention success, gaps in current knowledge, and implications for future research and clinical practice.
