Primary Outcome Measures:
  • Smoking Abstinence at 26 Weeks [ Time Frame: 26 weeks ]
    7 days of smoking abstinence confirmed biochemically at 26 week post quit attempt

  • Smoking Abstinence at 16 Weeks [ Time Frame: 16 weeks ]
    7 days of smoking abstinence confirmed biochemically at 16 weeks

  • Smoking Abstinence at 8 Weeks [ Time Frame: 8 weeks ]
    7 days of smoking abstinence confirmed biochemically at 8 weeks

  • Smoking Abstinence at 2 Weeks [ Time Frame: 2 weeks ]
    7 days of smoking abstinence confirmed biochemically at 2 weeks

Secondary Outcome Measures:
  • Alcohol Drinks Consumed Per Week Over a 2-week Period [ Time Frame: At 2, 8, 16, and 26-week follow-ups ]
    Average number of standard alcoholic drinks consumed per week over each 2-week period across the 26 weeks of follow-up as assessed by the Timeline Followback Interview. Standard alcoholic drink is defined as 12 oz of beer, 5 oz of wine, or 1.5 ounces of liquor.

Behavioral: Standard treatment plus brief alcohol intervention
Standard smoking cessation treatment with nicotine patch plus a brief alcohol-focused intervention

Detailed Description:
Heavy alcohol use frequently co-occurs with cigarette smoking and may impede smoking cessation. This clinical trial examined whether smoking cessation treatment that incorporates brief alcohol intervention can improve smoking cessation outcomes (7-day verified point prevalence abstinence) and reduce drinks consumed per week. Heavy drinkers seeking smoking cessation treatment were assigned by urn randomization to receive, along with 8-weeks of nicotine replacement therapy, either a 4-session standard smoking cessation treatment (ST, n = 119) or standard treatment of equal intensity that incorporated brief alcohol intervention (ST-BI, n = 117).

Ages Eligible for Study:   18 Years to 95 Years   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  1. be at least 18 years of age
  2. have smoked cigarettes regularly for at least one year
  3. currently smoke at least 10 cigarettes a day
  4. currently be using no other tobacco products or nicotine replacement therapy
  5. currently drink heavily according to self-report (>14 drinks per week or >5 drinks per occasion at least once per month over the last 12 months for men; >7 drinks per week or >4 drinks per occasion at least once per month over the past 12 months for women)

Exclusion Criteria:

  1. meet full DSM-IV criteria for alcohol dependence in the past 12 months
  2. meet criteria for other current psychoactive substance abuse or dependence (excluding nicotine dependence and alcohol abuse) in the past 12 months [this would also exclude individuals with lifetime substance dependence who continue to have some abuse/dependence symptoms in the past 12 months]
  3. meet criteria for current dysthymia, major depression, or manic episode [past month]
  4. are currently psychotic [past 12 months] or suicidal [suicidal ideation or intent in the past month]
  5. have an unstable medical condition that would suggest caution in the use of the nicotine patch (e.g., unstable angina pectoris, arrhythmia, recent congestive heart failure)
  6. are currently pregnant or lactating or intend to become pregnant. We also will exclude participants who are not alcohol dependent but who have characteristics that might make supervised alcohol detoxification necessary (e.g., morning drinking to avoid withdrawal, daily drinking of >12 drinks, recent withdrawal symptoms, history of severe withdrawal symptoms such as hallucinations, seizures, or delirium tremens).
