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.

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   Yes

Inclusion Criteria:

  • The sample, 40 women and 40 men, will be hospitalized patients recruited from Stanford Hospital and Clinics who report smoking at least 10 cigarettes per day prior to hospitalization, have confirmed tobacco use by cotinine testing, and an expected hospitalization of at least 3 days duration from the date of study enrollment. Intention to quit smoking will not be required for study participation.

Exclusion Criteria:

- Study exclusion criteria are: dementia or other brain injury precluding ability to participate; Alzheimer's Disease; Parkinson's Disease; Huntington's Disease; meningitis; seizure disorder of a sustained nature; delirium; brain surgery; drug and/or alcohol dependence; suicidal ideation; end-stage renal disease (i.e., on dialysis); hypertensive crisis; stroke; myocardial infarction (MI) with severe cardiac damage; pregnancy or breastfeeding; non-English speaking; complete homelessness; or currently engaged in tobacco treatment. Study staff will consult with clinical staff prior to approach for study enrollment. In cases of severe renal impairment (estimated creatinine clearance <30 mL/min), medical staff will consult with participants' physician to assess the appropriateness for study enrollment.
