Outcome measures

Outcome measures
Measure
Gemfibrozil
n=8 Participants
Participants in this arm will receive smoking cessation counseling and will be provided gemfibrozil 600 mg twice daily by mouth for 9 weeks, starting one week prior to target quit date and ending with study completion Gemfibrozil: FDA Approved Drug(s)/Biologic(s) (study use is not an FDA-approved use) smoking cessation counseling: smoking cessation counseling
Waitlist
n=8 Participants
Participants in this arm will receive the smoking cessation counseling but will not receive medication. After completing the trial without medication, participants who continue to smoke and have a desire to quit may choose to enter the gemfibrozil arm. smoking cessation counseling: smoking cessation counseling

SECONDARY outcome

Timeframe: 8 weeks after target quit date

The outcome measure was Heaviness of Smoking Index at exit. The Heaviness of Smoking Index is a two-item scale, with scores on each item rated on a 1-4 likert scale. The total score of the measure ranges from 2-8, with higher scores indicating worse outcome.
