Title: Randomized Double-blind Trial of Two Parallel Groups Design to Evaluate the Efficacy of Smoking Cessation With Combined (Varenicline Plus Nicotine Patches) Versus Monotherapy (Varenicline Plus Placebo Patches)
Brief Summary: The purpose of this study is to assess the efficacy of smoking cessation by using varenicline as monotherapy (VRN + placebo patches) or combined therapy (VRN + nicotine patches).

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 who have used bupropion (Zyban, or Wellbutrin) previously.
B: 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;

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).
