Nicotine Metabolism and Low Nicotine Cigarettes

Smoking Clinical Trial

Official title: Nicotine Metabolism and Low Nicotine Cigarettes

Status Completed

Clinical Trial Summary

This study examines the effects of smoking low nicotine cigarettes 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 for their responses to low nicotine cigarettes. The investigators hypothesize that individuals who smoke low nicotine cigarettes may smoke more intensely or smoke more each day, thereby maintaining their desired nicotine levels, and as a result continue to be exposed to significant toxin levels.

Clinical Trial Description

This study examines the effects of smoking low nicotine cigarettes on smoking behaviors and toxin exposure in fast and slow nicotine metabolizing smokers. We will recruit current smokers (split between slow and rapid nicotine metabolizing smokers) for a 35-day protocol. Participants will smoke their own brand cigarettes during a baseline 5 day period, followed by a 15-day period of smoking low nicotine content cigarette level 1: 0.25 mg nicotine content, followed by a 15-day period of smoking low nicotine content cigarette level 2: 0.08 mg nicotine content. This application is designed to provide empirical science to inform the FDA on the effect smoking low nicotine content cigarettes will have on use patterns and harm exposure. ;
