Varenicline on Reward Responses and Cognition in Adolescent Smokers

Completed · Phase 1 · Has a placebo group

Conditions studied: Tobacco Use Disorders

In brief

This is a pilot project using functional magnetic resonance imaging (fMRI) to examine the influence of varenicline on reward processing, cognitive control, and regulation of craving in adolescent smokers. We hypothesize that adolescent smokers receiving varenicline, when compared with those receiving placebo, will have differential brain responses to anticipation of rewards, during exposure to the Stroop task, and in response to tobacco cues.
