Evaluation of Deep Transcranial Magnetic Stimulation (DTMS) With the H-ADD Coil as an Aid to Smoking Cessation.

This is a multi center, randomized, double blind study to evaluate the safety and
effectiveness of the device as an aid to smoking cessation. 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.

Inclusion Criteria:

- 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.

Exclusion Criteria:

- Currently on Nicotine Replacement Therapy (NRT) or smoking cessation drugs (e.g.,
Zyban, Chantix, etc.) or undergoing behavioral smoking cessation interventions

- Cognitive or functional disability, diagnosed according to DSM-IV-TR criteria.

- Active psychiatric disorder according to DSM IV (Axis I and Axis II) criteria within
the last year.

- Alcohol or other substance abuse or dependence during the last 12 months before
recruitment.

- Subject is smoking any other form of tobacco or other substances.

- Subject is taking psychotropic medications on a regular basis.

- Subjects with a high risk for severe violence or suicidality as assessed during the
screening interview.

- Subjects who suffer from an unstable physical disease such as high blood pressure
(>150 mmHg systolic / diastolic > 110 mmHg) or acute, unstable cardiac disease.

- History of epilepsy or seizure (EXCEPT those therapeutically induced by ECT).

- Increased risk of seizure for any reason, including prior diagnosis of increased
intracranial pressure (such as after large infarctions or trauma), or history of
significant head injury or trauma with loss of consciousness for > 5 minutes.

- History of any metal in the head (outside the mouth).

- Metallic particles in the eye, implanted cardiac pacemaker or any intracardiac lines,
implanted neurostimulators, intracranial implant (e.g., aneurysm clips, shunts,
stimulators, cochlear implants, or electrodes) or implanted medical pumps.

- Individuals with a significant neurological disorder or insult including, but not
limited to:

- Any condition likely to be associated with increased intracranial pressure

- Space occupying brain lesion

- History of cerebrovascular accident

- Transient ischemic attack within two years

- Subjects suffering from significant hearing loss.

- 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.

- Participation in a clinical trial within the last 30 days before the beginning of this
clinical trial or similar participation in another clinical trial.
