Primary Outcome Measures:
  • 7 Day Point Prevalence Abstinence From All Forms of Tobacco [ Time Frame: 4 weeks after beginning study ]
    Self report of being quit for 7 continuous days at the time of the 4-week follow-up survey confirmed by saliva cotinine or urine anabasine verification.


Secondary Outcome Measures:
  • Nicotine Withdrawal and Urges to Smoke [ Time Frame: 4 weeks ]
  • Medication Compliance Rate [ Time Frame: 4 weeks after initial assessment ]
    This will be measured using two biomarkers collected from blood, urine, and saliva samples.

  • Time to First Cigarette Post-hospitalization [ Time Frame: 4 weeks ]
  • Stage of Change [ Time Frame: 4 weeks ]
  • Adverse Events [ Time Frame: 4 weeks ]
    Adverse effects assessed by structured checklist with choices of not present, mild, moderate, severe graded by FDA toxicity criteria.

Detailed Description:
The sample will be hospitalized patients smoking at least 10 cigarettes/day prior to hospitalization. Intention to quit smoking will not be required for study participation. Using a double-blinded, placebo-controlled, randomized design, participants will receive varenicline (0.5 mg BID as tolerated) or placebo during their hospitalization (Part 1) and will continue their study medication (placebo or active drug) for 4 weeks post-hospitalization (Part 2). Abstinence status will be examined at 4 weeks post-hospitalization.
