Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
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. Study Hypotheses: 1. that nicotine will produce greater positive and fewer negative/aversive subjective effects in individuals with ADHD. The study team also hypothesizes that nicotine will improve performance to a greater degree in those with ADHD. 2. that individuals in the ADHD group will exhibit an increase in choices for nicotine vs. placebo in both conditions (i.e., main effect) and that this effect will be more pronounced in the High Demand vs. Low Demand conditions (i.e. Group x Condition interaction). Also that greater performance enhancing effects of nicotine will be associated with greater nicotine choice during the high demand cognitive condition. 3. that the main effects of ADHD status on nicotine reinforcement will be heightened in the presence of certain genotypes. Also that the main effects of ADHD status on nicotine reinforcement will be heightened in the presence of certain genotypes. Finally that exposure to nicotine will alter epigenetic patterns in DNA
