Measuring Neuroadaptations in Response to Very Low Nicotine Content Cigarettes
For this study, 75 smokers will be randomly assigned to smoke research cigarettes with a very low or normal nicotine content. Participants will complete functional magnetic resonance imaging (MRI) scans at 2 in-person study visits to help us better understand how reducing nicotine intake affects decision making and reward processing.
There will be 2 in-person visits that require the following at each visit: MRI scan, saliva and urine samples. There are 2 remote visits conducted over Zoom. Subjects will be randomly assigned research cigarettes that will replace their normal cigarettes for 6 weeks between their 2 MRI scans. There will be surveys to complete and daily smoking logs to keep.
