We are currently recruiting adult (aged 25-55) smokers and ex-smokers for a study on how smoking status affects individual’s brain and behavior. The study consists of a two-hour screening session, followed by a two-and-a-half hour study session. During the study session, you will undergo magnetic resonance imaging (MRI) and complete some computer tests and questionnaires.

You will be compensated for the study visits.
