The purpose of this study is to provide preliminary information on the effect of electronic nicotine delivery systems (ENDS) provisions and contingent incentives (CI) on smoking in individuals with overweight/obesity who smoke cigarettes (SWO). All participants will be provided information on the comparative risk of ENDS relative to cigarette smoking, and a randomized group of participants will be provided ENDS provisions for 6 weeks. All participants will complete breath samples for 28 days to measure their exhaled carbon monoxide and will either receive fixed incentives for sample completion or receive varying incentives contingent on their carbon monoxide levels. Researchers will compare groups to understand the effect of each condition on smoking-related behavior.
