Summary

This study involved 71 African American menthol smokers to see how the availability of e-cigarette flavors like menthol or tobacco changes their smoking habits, toxin exposure, and addiction risk. Participants were surveyed daily about cigarette use and tested for carbon monoxide levels. The goal was to understand how flavor regulations might influence behavior and health.
