Brief Summary
The purpose of the proposed study is to conduct a randomized, double-blind clinical trial to compare adjunct treatment with 50 mg oral naltrexone vs. placebo in conjunction with standard smoking cessation treatment with nicotine patch and counseling. Hypotheses:
- 1.Naltrexone will improve smoking cessation quit rates, as measured at the end of active treatment (3 months) and during long term follow up (1 year).
- 2.Weight and smoking-related variables (i.e., less weight gain, as well as reduced craving and withdrawal) will be important factors by which naltrexone improves smoking cessation outcome.
- 3.These effects are predicted to be stronger in women compared to men.

Outcome Measures
Primary Outcomes (6)
Prolonged Smoking Abstinence: 4 Weeks Post Quit-Date
Prolonged Abstinence at 4 weeks post quit date (Study Week 7). Prolonged Abstinence defined as not smoking (even a puff of a cigarette) at any point during the previous time frame, allowing for a 1-week grace period.
4 Weeks Following Smoking Quit Date (Study week 7)
Prolonged Smoking Abstinence: 12 Weeks Post Quit-Date
Prolonged Abstinence at 12 weeks post quit date (Study Week 15). Prolonged Abstinence defined as not smoking (even a puff of a cigarette) at any point during the previous time frame, allowing for a 1-week grace period.
12 Weeks Following Smoking Quit Date (Study week 15)
7-Day Point Prevalence Smoking Abstinence: 4 Weeks Post Quit-Date
7-Day Point Prevalence smoking abstinence at 4 weeks post quit date (Study Week 7). 7-Day Point Prevalence abstinence defined as not smoking (even a puff) for seven days in a row or on one day in each of two consecutive weeks during the previous time frame.
4 Weeks Following Smoking Quit Date (Study week 7)
7-Day Point Prevalence Smoking Abstinence: 12 Weeks Post Quit-Date
