Title: Varenicline, an Alpha 4 Beta 2 Nicotinic Acetylcholine Receptor Partial Agonist, on Cognitive Dysfunction in 120 Patients With Schizophrenia: a Randomized, Double Blind, 8 Weeks Trial
Brief Summary: The primary objective of this project is to examine the effects of varenicline treatment used concomitantly with antipsychotic medications, on cognitive dysfunction in people with schizophrenia.

This study will be a randomized, double blind, parallel group, placebo controlled 8 weeks trial.

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;

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.
