Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Project 2 will evaluate the impact of very low nicotine content cigarettes, e-cigarette nicotine content, and e-cigarette flavoring on cigarettes smoked per day, nicotine exposure, puff topography, discomfort/dysfunction, other health-related behaviors, nicotine/tobacco dependence, biomarkers of tobacco exposure, intention to quit, compensatory smoking, other tobacco use, cardiovascular function, and perceived risk. Project 2 will also evaluate differences between conditions in compliance with product use and the ability to abstain from cigarette smoking when provided a financial incentive for abstinence from combusted tobacco. This is not a treatment program for smoking.
