Outcome Measures

Primary Outcomes (1)

  • Change in Self-Reported Craving Level Via Lab-Based Cue Reactivity

    Participants were asked to self-report craving level to smoke on a scale of 1-10 with 1 corresponding to no craving and 10 corresponding to intense craving. Self-reported craving level was requested following presentation of multiple images on a screen over a 20 minute period. Four types of images were presented - neutral affect, negative affect, smoking and social images.

    Baseline, Visit 4 (week 6)

Secondary Outcomes (5)

  • Change in Self-Reported Craving Level Via Real-World Cue Reactivity

    Baseline, Visit 4 (week 6)

  • Changes in Smoking

    Screening visit, Visit 4 (week 6)

  • Medication Adherence

    Screening visit, Visit 4 (week 6)

  • Medication Tolerance by Self-Reported Side Effects

    Up to 12 weeks

  • Changes in Smoking Abstinence

    Screening visit, Visit 4 (week 6)

Contraceptive measures such as rhythm method or Plan B™, sold for emergency use after unprotected sex, are not acceptable methods for routine use.
  • Have access to a cell phone that can send and receive SMS text messages.

You may not qualify if:

  • Use of a smoking cessation medication (e.g. nicotine replacement, varenicline, bupropion) in last 30 days.
  • Current use of tobacco product other than cigarettes (e.g. e-cigarettes, smokeless tobacco) in the last 30 days
  • Answer \> 0 on suicidality question of Patient Health Questionnaire (PHQ-9) Depression Scale
  • Active alcohol use disorder or hazardous drinking. This will be screened with the AUDIT-C, and positive scores (4 or greater for men and 3 or greater for women)54,55 will result in study clinician assessment and discretion.
  • Use of illicit drugs in the last month (marijuana, cocaine, opiates, benzodiazepines, and/or methamphetamine)
  • Severe symptomatic depression and or anxiety (study medical provider discretion)
  • Diagnosis of bipolar disorder, schizophrenia, PTSD and or adult ADHD (study medical provider discretion)
  • Chronic medical illness including diabetes with the use of insulin, Hemoglobin A1c \> 7 (study medical provider discretion), heart disease diagnosed by angiogram, or COPD diagnosed by pulmonary function testing and requiring an oxygen supply
  • Specific medications (Appendix 1)
  • Abnormal finding on physical exam (study medical provider discretion)
  • Positive Urine Pregnancy Test (women of child bearing potential only; QuickVue Urine Pregnancy)56
  • Positive Urine Toxicology-5 Screen (methamphetamine, cocaine, opiates, benzodiazepines, THC)
  • Unstable hypertension (Blood pressure \> 160/100)
  • Renal failure with active or pending hemodialysis
