* Significant medical or neurologic illness

* a condition that increased the risk of seizure (e.g., serious head trauma with loss of consciousness
* uncontrolled hypertension (BP \>160/100) in hospital

We will not exclude participants based on their prior use of cessation medication or if they use multiple tobacco products in order to enhance real-world generalization (these will be statistically controlled in analyses); not currently attempting to quit smoking; not intending to quit smoking (defined as no plans to quit in the next month); and planning to remain in the intervention catchment area for at least 12 months.

D: Inclusion Criteria:

* Laboratory evaluations (kidney and liver) outside normal limits and of potential clinical significance in the opinion of the investigator
* Serious or unstable disease within the past 3 months
* History (last 3 months) of abnormal heart rhythms, cardiovascular disease (stroke, angina, heart attack) may result in ineligibility; these conditions will be evaluated on a case by case basis by the study physician
* Current use of certain medications: (1) smoking cessation meds (last 7 days), i.e., Wellbutrin, Bupropion, Zyban, nicotine replacement therapy (NRT), Chantix, (2) certain medications to treat depression (last 14 days), i.e. monoamine oxidase inhibitors (MAOIs) and Elavil (Amitriptyline), (3) a case by case determination will be made by study physician for medication on precautionary list, i.e. nitroglycerin, or (4) daily use of opioids for 30 days or more on phone screen or at screening is exclusionary however pro re nata (PRN) use is allowed (i.e., 3:7 days per week or less or if more frequent, use less than a month's duration)
