Our faculty conduct a diverse body of research on tobacco and nicotine use and exposure, ranging from longitudinal studies on the initiation of electronic and combustible cigarette use in adolescence to studies of smoking cessation and environmental tobacco smoke avoidance in adulthood.

Our researchers conduct laboratory-based studies to investigate the reinforcing properties of nicotine, the effects of smoking abstinence, and the effects of pharmacotherapies on smoking, mood, and behavior. They also conduct randomized controlled trials to test novel behavioral and pharmacological methods of helping smokers quit, including studies using motivational interviewing, positive psychology, physical activity promotion, and contingency management to improve smoking outcomes. Smoking cessation interventions employ in-person counseling, text messaging, video, and web-based programs.

A particular focus of our tobacco research touches upon smoking cessation and the impact of tobacco regulatory policies in underserved and high-risk groups including: smokers with substance use disorders; smokers who drink alcohol heavily; pregnant women; people living with HIV; sedentary smokers; racial, ethnic, and sexual minorities; and people living with mental illness.
