Brief Summary
The purpose of this research program is to understand how a biomarker called the "nicotine metabolite ratio" (also referred to as NMR) may influence a smoker's ability to quit smoking.

Outcome Measures
Primary Outcomes (1)
7-day Point Prevalence Quit Rate at End-of-Treatment (EOT)
The percentage of ITT subjects who were verified as abstinent. Abstinence was defined as no self-reported smoking (not even a puff) for at least 7 days before the telephone assessment, with in-person verification for those self-reporting abstinence. In-person verification consisted of breath carbon monoxide analysis, with a reading of 8 parts-per-million or less confirming abstinence. Subjects who were lost to follow-up were considered smokers.

Study Arms (6)
Placebo (Slow Metabolizers)
PLACEBO COMPARATORSubjects in this arm are those identified as slow metabolizers of nicotine (based on their NMR) and will take placebo pills daily for twelve weeks \& wear a placebo patch daily for eleven weeks. The placebo pill will look identical to the active varenicline tablets; however, they will not contain any active medication. Subjects will follow the same drug regimen as those in the active varenicline arm. The placebo patch will look identical to the active transdermal nicotine patches; however, they do not contain actual nicotine. Subjects will follow the same regimen as those in the active transdermal nicotine arm. All subjects in this arm will receive smoking cessation counseling during their sessions.
Varenicline (Slow Metabolizers)
ACTIVE COMPARATORSubjects in this arm are those identified as slow metabolizers of nicotine (based on their NMR) and will take active varenicline pills daily for twelve weeks \& wear a placebo patch daily for eleven weeks. When taking the active varenicline, subjects will follow the same treatment regimen per the manufacturer. The placebo patch will look identical to the active transdermal nicotine patches; however, they do not contain actual nicotine. Subjects will follow the same regimen as those in the active transdermal nicotine arm. All subjects in this arm will receive smoking cessation counseling during their sessions.
Transdermal Nicotine (Slow Metabolizers)
ACTIVE COMPARATORSubjects in this arm are those identified as slow metabolizers of nicotine (based on their NMR) and will take placebo pills daily for twelve weeks \& will wear an active transdermal nicotine patch daily for eleven weeks. The placebo pill will look identical to the active varenicline tablets; however, they will not contain any active medication. Subjects will follow the same drug regimen as those in the active varenicline arm. When wearing the active transdermal nicotine, subjects will follow the same treatment regimen per the manufacturer. All subjects in this arm will receive smoking cessation counseling during their sessions.
Placebo (Normal Metabolizers)
PLACEBO COMPARATORSubjects in this arm are those identified as normal metabolizers of nicotine (based on their NMR) and will take placebo pills daily for twelve weeks \& wear a placebo patch daily for eleven weeks. The placebo pill will look identical to the active varenicline tablets; however, they will not contain any active medication. Subjects will follow the same drug regimen as those in the active varenicline arm. The placebo patch will look identical to the active transdermal nicotine patches; however, they do not contain actual nicotine. Subjects will follow the same regimen as those in the active transdermal nicotine arm. All subjects in this arm will receive smoking cessation counseling during their sessions.
Varenicline (Normal Metabolizers)
ACTIVE COMPARATORSubjects in this arm are those identified as normal metabolizers of nicotine (based on their NMR) and will take active varenicline pills daily for twelve weeks \& wear a placebo patch daily for eleven weeks. When taking the active varenicline, subjects will follow the same treatment regimen per the manufacturer. The placebo patch will look identical to the active transdermal nicotine patches; however, they do not contain actual nicotine. Subjects will follow the same regimen as those in the active transdermal nicotine arm. All subjects in this arm will receive smoking cessation counseling during their sessions.
Transdermal Nicotine (Normal Metabolizers)
ACTIVE COMPARATORSubjects in this arm are those identified as normal metabolizers of nicotine (based on their NMR) and will take placebo pills daily for twelve weeks \& will wear an active transdermal nicotine patch daily for eleven weeks. The placebo pill will look identical to the active varenicline tablets; however, they will not contain any active medication. Subjects will follow the same drug regimen as those in the active varenicline arm. When wearing the active transdermal nicotine, subjects will follow the same treatment regimen per the manufacturer.

All subjects must consent to use a medically accepted method of birth control (e.g., condoms and spermicide, oral contraceptive, Depo-Provera injection, contraceptive patch, tubal ligation) or abstain from sexual intercourse during the time they are taking study medication (pills and patches) and for at least one month after the medication period ends. All female subjects of child-bearing potential should not be pregnant for the duration of the study.
You may not qualify if:
- Smoking Behavior

- Current enrollment or plans to enroll in another smoking cessation or research program in the next 12 months.
- Plan to use other nicotine substitutes or smoking cessation treatments in the next 12 months.
- Provide a baseline CO reading less than or equal to 10ppm at the Intake Session.
- History (within the last year) or currently receiving treatment for substance abuse (e.g., alcohol, opioids, cocaine, marijuana, or stimulants), excluding nicotine.
- Current use of cocaine and/or methamphetamines (urine drug screen at the Intake Session).
- Current alcohol consumption that exceeds greater than 25 standard drinks/week.
- Current alcohol abuse or dependence.
- Current non-alcoholic psychoactive substance abuse or dependence.
