Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
OTHER: Abstinent
All participants received varenicline. A priori determined analysis was between participants who quit smoking and those who continued to smoke. This arm was abstinent after 5 weeks of varenicline treatment.. |
Participants will be treated with a standard course of varenicline, 0.5 mg 1 tablet every day for 3 days, then 0.5 mg 1 tab twice a day for four days, and 1 mg 1 tablet twice a day for three months.

Measure Description |
Time Frame |
---|---|---|
Change in Post-Resist Craving
Time Frame: 5 weeks
|
Change in Post-resist task craving between Scan 1, pre-medication, and Scan 2, post- medication, as measured on a 0-10 Likert scale.
The Within Sessions Rating scale (Range 0-10) measures craving with 0 indicating Not at All and 10 indicating Extremely.
Change scores were calculate by subtracting the craving score immediately following the pre-medication scan from the craving score immediately following the post-medication scan.
