This study investigated the impact of public health campaigns on smoking cessation rates through a cross- sectional analysis of 1,200 adults recruited using stratified random sampling from community centers and health clinics. The research evaluated the effectiveness of different campaign intensities and content types while identifying key demographic and psychological predictors of cessation success. Results demonstrated significantly higher cessation rates among individuals exposed to campaigns (47.4%) compared to those not exposed (23.2%), with a clear dose-response relationship between campaign intensity and cessation success. Logistic regression analysis identified significant predictors of cessation, including campaign exposure (OR=2.31), campaign intensity (OR=1.23 per unit increase), health risk messaging (OR=1.48), higher self- efficacy (OR=1.38), and greater motivation (OR=1.26). Notable demographic disparities were observed, with lower cessation rates among females (OR=0.78) and individuals of low socioeconomic status (OR=0.52). The findings support the efficacy of comprehensive public health campaigns for smoking cessation while highlighting the need for targeted approaches to address persistent socioeconomic and gender disparities. The study concludes that optimally effective cessation campaigns should employ high-intensity, multi-content approaches while incorporating strategies to enhance psychological factors such as motivation and self-efficacy. Key Words: Public Health, Campaigns and Smoking Cessation Background Public health campaigns have long been recognized as vital tools in the fight against smoking, with their primary objective being to reduce smoking prevalence and encourage cessation among individuals (Nicholas & Sarah, 2024). These campaigns utilize various communication strategies and media platforms to disseminate information about the harmful effects of smoking, promote cessation resources, and foster a supportive
