Conducted by: Guohua Xia, MD, PhD
324 Madson Place, Suite 150
Davis, CA 95618
This is a multicenter study involving the use of a novel form of treatment methodology called deep Transcranial Magnetic Stimulation (dTMS) in the Aid of Smoking Cessation. This is a Non-Pharmaceutical, Non-Invasive form of treatment that we are investigating. Treatment will be administered over a 6 week period and follow-up assessments will be conducted at 4 months. The clinical study design includes multiple measurements of safety and effectiveness parameters. The design is meant to demonstrate that the device shows superiority compared to sham treatment over six treatment weeks, at the 4 months follow up.
- Male or female subjects, 22-70 years old.
- Chronic, heavy (>10 cigarettes/day) smokers, who smoke for more than 1 year, with no period of abstinence for greater than 3 months during the past year.
- Subjects who are motivated to quit smoking (with responses "very likely," or "somewhat likely" to the motivation questionnaire).
- Satisfactory answers on safety screening questionnaire for transcranial magnetic stimulation (Keel 2001).
- Gave informed consent for participation in the study.

- Subjects taking pro-convulsant medications (e.g., antidepressants or antipsychotic medications).
- Previous treatment with TMS.
- Subjects who cannot communicate reliably with the investigator or who are not likely to cope with the requirements of the experiment.
