Study Summary

This study examines the effects of smoking little cigars in different groups of smokers. The investigators are focusing on differences in how smokers' bodies break down and eliminate nicotine from their systems. Some people are fast metabolizers of nicotine, meaning they break down and eliminate nicotine from their bodies more quickly. Other people are slower metabolizers meaning they break down and eliminate nicotine more slowly. The investigators are comparing these two groups of smokers when they switch to smoking cigars instead of cigarettes.

Primary Outcome

The number of cigars smoked each day.

Interventions
