Title: A Comparison of Bupropion SR and Placebo for Smoking Cessation
Brief Summary: The purpose of this study is to examine whether the adjunctive use of bupropion SR in the context of a psychoeducational program modified for people with schizophrenia might improve the likelihood of successful abstinence in this population. If bupropion SR is effective for reducing cigarette smoking, then it will be important to determine if decreased nicotine intake is associated with a worsening of psychotic, anxiety or depressive symptoms. In addition, it would be important to determine the effect that a reduction in nicotine stimulation would have on patient's cognitive functioning, as nicotinic receptors have been shown to regulate attention and memory function, and it is hypothesized that these functions are normalized by acute nicotine administration in people with schizophrenia
