Arm 2

Arm Type

Arm Label

Smoking Abstinence

Ad Lib Smoking

Arm Description

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

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.

Outcomes

Primary Outcome Measures

Blood Oxygen Level Dependent (BOLD) Activation
BOLD activation in brain reward network regions
Ecological Momentary Assessment (EMA) Pleasure Ratings
Anticipated and experienced pleasure based on self-report ratings acquired each day during the EMA phase

5. Study Description

Brief Summary
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.

12. IPD Sharing Statement

Plan to Share IPD
Yes
IPD Sharing Plan Description
Detailed protocols, datasets and additional information will be available from the Principal Investigator and research team upon request. In order to maintain compliance with the Health Insurance Portability and Accountability Act (HIPAA) requirements, as well as university data security policies, all data will be anonymized according to HIPAA guidelines prior to being shared. Individual participant scripts will not be made publicly available due to privacy concerns and because this could impact the nature of information participants were willing to provide for scripts. Data will be provided in widely accessible formats for both self-report and imaging data. We will work with relevant administrative offices to obtain guidance regarding any required Data Use Agreements as needed.
IPD Sharing Time Frame
We anticipate making data available within 6 months of study completion. It will be available for an indefinite period of time.
IPD Sharing Access Criteria
Contact PI for details.
