Patients with schizophrenia have high rates of cigarette smoking and tobacco dependence, and great difficulties in quitting smoking. The development of novel and more effective treatments for tobacco dependence in this population is thus needed. This study will test the hypothesis that repetitive transcranial magnetic stimulation (rTMS) may facilitate smoking cessation with the transdermal nicotine patch (TNP) in patients with schizophrenia motivated to quit smoking. A total of N=40 smokers with schizophrenia would be assigned to either active rTMS (N=20) or sham rTMS (N=20) as a treatment regimen of 5X/week treatments for four weeks. All subjects would receive TNP (21 mg/24h) and weekly group behavioral therapy for smoking cessation for a total of 10 weeks. The investigators predict that active rTMS will be well-tolerated and superior to sham rTMS for enhancing smoking cessation rates in smokers with schizophrenia.
