Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study is designed to find out how smoking affects the way the brain responds to pleasure and how this impacts smokers' behavior. Participants will complete three sessions. The first session will be a screening and training visit to determine final eligibility. Eligible participants will work with a researcher to develop brief scripts about times when they smoke and do other activities. Next, participants will attend two magnetic resonance imaging (MRI) scans - one after abstaining from smoking for 24 hours and the other after smoking as usual. After the second MRI, participants will answer questions on their phone every day for two weeks.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Smoking Abstinence

Participants will abstain from smoking for 24 hours before one MRI scan. Smoking abstinence will be confirmed using exhaled carbon monoxide breath testing

Group Type OTHER

Smoking Abstinence

Intervention Type OTHER

Participants will abstain from smoking for 24 hours.

Ad Lib Smoking

Participants will continue smoking as usual (i.e. "ad lib") before one MRI scan and smoke one additional cigarette immediately prior to scanning. Continued smoking will be confirmed using exhaled carbon monoxide breath testing.

Group Type OTHER

Ad Lib Smoking

Intervention Type OTHER

Participants will continue smoking as usual (i.e. ad lib) and smoke one cigarette of their own brand immediately prior to scanning.
