Title: A Twelve-Week, Double-Blind, Placebo-Controlled, Randomized, Multicenter Study With Follow-up Evaluating the Safety and Efficacy of Varenicline Tartrate ( CP-526,555) in Comparison to Zyban for Smoking Cessation
Brief Summary: The primary purpose of this study is to evaluate the safety and efficacy of varenicline given for a twelve week treatment period in comparison with placebo and Zyban for smoking cessation.


Options:
A: Inclusion Criteria:

* Subjects must have smoked an average of at least 10 cigarettes per day during the past year and over the month prior to the screening visit, with no period of abstinence greater than 3 months in the past year.

Exclusion Criteria:

* Subjects with clinically significant, recent cardiovascular disease.
B: Inclusion Criteria:

* Subjects must have smoked an average of at least 10 cigarettes per day during the past year and over the month prior to the screening visit, with no period of abstinence greater than 3 months in the past year.

Exclusion Criteria:

* Subjects who have used bupropion (Zyban or Wellbutrin) previously.
C: We are only recruiting by invitation only (to members of our past cohort). We will open up enrollment to the public in the Madison, WI and Milwaukee WI areas at the end of 2012.

Inclusion Criteria:

a. To be eligible for the Comparative effectiveness trial, participants must:

* smoke 5 or more cigarettes per day,
* desire to quit smoking but not be currently engaged in cessation treatment,
* be medically eligible to use either combination NRT or varenicline,
* have reliable phone access,
* if female, must not be pregnant and must be willing to use an acceptable birth control method.

Exclusion Criteria:

1. There are no exclusion criteria for participating in the main health outcomes study, other than being unwilling to complete study assessments.
2. All smoking participants from new and original cohorts will be excluded from the cessation trial for the following reasons:

   * end-stage renal disease with hemodialysis;
   * prior suicide attempts within the last 5 years or current suicidal ideation;
   * diagnosis of and/or treatment for schizophrenia;
   * other psychotic disorders or bipolar disorder within the last 10 years;
   * current PHQ-9 score indicative of moderately severe depression;
   * severe untreated hypertension \>200/100 mmHg;
   * currently taking Wellbutrin, Zyban or bupropion;
   * hospitalized for a stroke, heart attack, congestive heart failure or diabetes within the last year;
   * used pipe tobacco, cigars, snuff or chew more than twice in the past week.

It should be noted that if any incidental findings appear in any of the cardiology tests (e.g., ultrasound, tonometry, ECG, or exercise stress test; see forms in Supplemental Information section of application), the study cardiologist (Dr. Stein or his designee) will be assign the participant to the non-randomized treatment arm and they will be given the nicotine patch and the same counseling intervention as CET participants. They will not be included in the CET analyses. This will be done to properly address the cardiovascular risk warning from the FDA regarding varenicline (Chantix).
D: Inclusion Criteria:

* Have a diagnosis (using the SCID-I/P at screening visit) of schizophrenia or schizoaffective disorder and judged to be stable (without hospitalization or acute exacerbation and functioning in society) on psychiatric treatment for at least the past 6 month.

* Score 7 or higher on the Contemplation Ladder at the Screening, Week -1, and Baseline Visits.

Exclusion Criteria:

* PANSS score \>70 at Screen or Baseline Visit.
* Subjects hospitalized within the past six months due to suicidal ideation or suicidal behavior or subjects considered to have serious suicidal ideation or suicidal behavior within the past six moth.
