Nicotine, Non-Smokers With and Without ADHD, and Genetics Study

This study will use nicotine nasal spray to safely and effectively model the effects of initial smoking experiences in nonsmokers. Neither the safety nor the effectiveness of this drug will be assessed. The overall goal of the proposed research is to evaluate the behavioral and genetic mechanisms of smoking risk in non-smoking young adults (aged 18-25 years of age) with and without ADHD using a novel laboratory-based model of intranasal nicotine administration. The effects of two doses of intranasally administered nicotine versus placebo will be assessed. In addition, nicotine self-administration will be evaluated under conditions that are likely to be more cognitively challenging among individuals with ADHD.
