This study is to learn about how teenagers think about risks and benefits regarding smokeless and other tobacco products, what can be done to reduce tobacco risk, and what interventions and policies we can develop to reduce tobacco use. The study will also find if certain teenagers process nicotine faster than others making them at higher risk for nicotine addiction. This study is being funded by the National Institutes of Health (NIH) and the Food and Drug Adminstration (FDA). Information from this study will help educators and health professionals better communicate with teenagers about tobacco use.
