Study Summary

Male and female smokers were recruited to undergo 2 phases of smoking cessation. Each phase was 4 days long and involved 3 brain-imaging scans, blood draws and an intervention involving progesterone or a matched placebo.

Primary Outcome

GABA concentrations (collected in the Dorsal Anterior Cingulate Cortex \[DACC\]) will be obtained using the non-invasive neuroimaging method of proton magnetic resonance spectroscopy (1H-MRS) both before and after placebo administration and smoking abstinence. In total subjects will undergo 6 1H-MRS scans. The 6 1H-MRS scans take place over a period of approximately 1-2 months. Each paradigm (placebo/progesterone) takes approximately one week, with an approximately two-week wash in between parad
