This research study explored the behaviour of smokers in purchasing single sticks; and identified enforcement options on banning sales of single stick cigarettes. The overarching objective was to strengthen evidence on the likely impact and effective implementation of the proposed single stick ban. The study used a literature survey, Key Informant Interviews (KIIs), observational survey and country case studies. It was identified that nearly 81% of smokers are buying single sticks and it is important to note that none of the smokers were buying cigarettes as a pack or more than five sticks in Sri Lanka. Further, a higher percentage (70%) of the smokers were between age 20-40. Based on all the research findings it was clear that to reduce the consumption of cigarettes among ‘Last Mile’ smokers, Sri Lanka needs to ban the sales of single stick cigarettes or cigarettes in loose form.
