About

This study will analyze a series of biological and behavioral markers in different populations of smokers. The study groups will differ in their cigarette consumption and level of nicotine dependence. This analysis will help to identify factors that might be important for smoking behavior and nicotine addiction. The results from this study will contribute to improve campaigns for smoking prevention and treatments for smoking cessation.
