Brief Summary:

The purpose of the study was to determine how the treatments for cigarette craving work.

Hypothesis: During exposure to cigarette-related cues, heavy smokers will have greater reductions in regional brain activation from before to after both forms of active treatments than from before to after placebo.


Condition or disease Intervention/treatment Phase
Nicotine Dependence Drug: Zyban Phase 1

Detailed Description:
PET and fMRI scanning were used to examine brain activity and activation in cigarette smokers in response to cigarette-related cues.
