Study Summary
The overall purpose of this study is to determine the effects of using charcoal-filtered cigarettes on product perceptions, smoking behaviors, and biomarkers of exposure to tobacco-related toxicants. The main questions it aims to answer are: Do perceptions of cigarettes differ by their filter? Do people smoke charcoal-filtered cigarettes differently than cigarettes with conventional filters, and does this change their exposure to cigarette harms? Study participants will complete a 5-week laboratory-based, open-label, parallel-design randomized trial. After a baseline period of smoking their preferred brand, participants will smoke charcoal-filtered or non-charcoal-filtered cigarettes for 4 weeks while completing weekly sessions to assess primary outcomes. During weekly sessions, they will smoke two cigarettes in our laboratory, provide urine and carbon monoxide samples, and complete questionnaires.
Primary Outcome
Risk beliefs will be captured via 8 items rated on a 5-point Likert scale (1 = "definitely untrue", 5 = "definitely true") that evaluate participants' preferred brand and the cigarettes they smoke on the following beliefs: a) "lower in nicotine", b) "lower in tar", c) "less addictive", d) "less likely to cause cancer", e) "has fewer chemicals", f) "is healthier", g) "makes smoking safer", h) "helps people quit smoking." Individual items will be scores as correct or incorrect, and incorrect respo
