Abstract Background India bears the highest global burden of oral cancer, despite having an operational tobacco cessation framework. Occupational groups like solid waste management personnel face significant health challenges due to prevalent tobacco use, leading to oral potentially malignant lesions and oral cancer. Enhanced tobacco control strategies are essential for these groups. Methods A pre-post interventional, community-based study enrolled 1200 municipal workers in Varanasi, India, from July 2022 to August 2023. 858 tobacco users underwent screening and were randomly assigned to one of three interventions: Very Brief Advice, Individual Behavioral Counseling, or Group Behavioral Therapy. Follow-up was conducted one year after the baseline interventions Effectiveness was measured by nicotine dependence reduction using the Fagerstrom Test for Nicotine Dependence (FTND) scores and cessation rates defined as at least 6-month abstinence. Appropriate statistical tests assessed the burden of tobacco use, oral potentially malignant lesions, and pre-post differences in FTND scores within and between groups. A p-value of < 0.05 was considered statistically significant. Results Municipal workers exhibited a high prevalence (71.5%) of smokeless tobacco (SLT) use. One-third (32.9%) of the participants screened positive for oral potentially malignant lesions and oral cancer. Leukoplakia was the most common lesion. Screened positivity correlated with significant nicotine dependence. Among 494 follow-up participants, 47.1% reported a significant reduction in nicotine dependence across all intervention groups. Quade's ANCOVA indicated significant differences in post-test FTND scores, with individual behavioral counselling showing the greatest reduction. However, no cessation was achieved in any group despite the significant decline in dependence. Conclusion Solid waste management personnel in Varanasi show heightened SLT use and associated oral potentially malignant lesions. The persistent tobacco use in these high-risk occupational populations undermines government tobacco control efforts and highlights the need for robust policy and implementation strategies. The study demonstrated a significant reduction in nicotine dependence following interventions, though tobacco cessation was not achieved. More frequent interventions and addressing quitting barriers-such as cultural norms, lack of awareness, easy accessibility, and adverse working conditions-are crucial. Developing a tailored workplace model to tackle tobacco use in occupational settings may facilitate cessation.
