Summary

The purpose of this proposed pilot study is to examine the use of varenicline in people with schizophrenia to specifically assess tolerability and efficacy for smoking cessation. Specifically, The primary objective of this pilot study is to determine if taking of varenicline along with an individual smoking cessation supportive program is a safe and effective treatment of nicotine addiction in schizophrenic patients. We hypothesize that the varenicline treated patients will achieve higher rates of smoking cessation than those who receive placebo and individual support.
