Study Summary
The purpose of the study is to learn more about tobacco dependence and nicotine metabolism in African-Americans and whites, by studying to see if how fast a person metabolizes nicotine (how the body breaks down nicotine into inactive compounds) affects how dependent they are on smoking cigarettes. The investigators believe that people with a faster rate of metabolism may have more severe nicotine withdrawal symptoms and also may have a harder time trying to quit smoking.
Primary Outcome
Total withdrawal score as measured by Minnesota Nicotine Withdrawal Scale
Interventions
- BEHAVIORAL Smoking abstinence
