Study Overview
Brief Summary
To examine the influence of current daily tobacco smoking on brain activation during stress, tobacco cue, and neutral relaxing conditions
Detailed Description
Subjects will participate in an fMRI session to examine changes in frontal and limbic brain regions with tobacco cues, stress and neutral/relaxing imagery. During each fMRI session subjects will participate in six imagery trials: 2 different neutral/relaxing, 2 different stress and 2 different tobacco cue scripts.
