Theta-burst Repetitive Transcranial Magnetic Stimulation (TBS) of the Right Inferior Frontal Gyrus for Treatment of Nicotine Dependence

The purpose of this research study is to examine the effects of theta-burst Transcranial Magnetic Stimulation on inhibitory control and smoking among adult cigarette smokers. In a double-blind, sham controlled trial, investigators will examine the effects of 12 sessions of cTBS on executive function and smoking behavior.
