The purpose of this study is to develop repetitive transcranial magnetic stimulation (rTMS) as a potential treatment for nicotine addiction. Repetitive TMS is a non-invasive technique that uses magnetic pulses to temporarily stimulate specific brain areas in awake people (without the need for surgery, anesthetic, or other invasive procedures). This study will test whether rTMS over the forehead can produce a reduction in brain activity associated with craving that may prompt you to want to smoke cigarettes.
