Brief Summary:
The primary objective of this study is to evaluate the impact of substance-abuse treatment as usual plus smoking-cessation treatment (TAU+SCT), relative to substance-abuse treatment as usual (TAU), on drug-abuse outcomes. Specifically, this study will evaluate whether concurrent smoking-cessation treatment improves, worsens, or has no effect on stimulant-use outcomes in smokers who are in outpatient substance-abuse treatment for cocaine or methamphetamine dependence.

Arms and Interventions

Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Arm Intervention/treatment
Experimental: Smoking-cessation treatment + substance treatment as usual Other: Smoking-cessation treatment
Smoking cessation treatment includes four components: 1. brief weekly individual smoking-cessation counseling study weeks 1-10; 2. extended-release (XL) bupropion (300 mg/day)study weeks 1-10; 3. nicotine inhaler (6-16 cartridges per day ad libitum)during the post-quit treatment phase; 4. prize-based contingency management during the post-quit treatment phase.
No Intervention: Substance-treatment as usual
Treatment as usual is outpatient stimulant-dependence treatment as typically provided by the participating site.


Outcome Measures

Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Stimulant-free Weeks Assessed by Self-report and Twice-weekly Urine Drug Screens [ Time Frame: Week 16 ]
    Stimulant-free week results (no cocaine, methamphetamine and amphetamine use) were obtained by combining the urine drug screens (UDS) and the self-reported Timeline Follow-Back (TLFB). At the group level, this outcome translates into the percentage of weeks in each study arm that are stimulant-free.


Secondary Outcome Measures :
  1. Point-prevalence Abstinence (Smoking Outcome) [ Time Frame: Week 10 assessment ]
    point-prevalence abstinence defined as not smoking in the previous seven days based on self-report and confirmed with a Carbon Monoxide (CO) level ≤ 8 ppm

  2. Four Week Continuous Smoking Abstinence [ Time Frame: Post-quit days 15-42 ]
    A combination of daily self-reported smoking data and weekly carbon monoxide levels were used to determine continuous abstinence during post-quit days 15 - 42.

  3. Stimulant-free Results at 3-month Visit [ Time Frame: 3-month follow-up visit ]
    At the 3-month follow-up visit, percentage of participants with a negative urine drug screen for stimulant use and no stimulant use days reported during the past 28 days based on Timeline Follow-back.

  4. Point-prevalence Abstinence (Smoking Outcome) 3 Month Visit [ Time Frame: 3- month follow-up visits ]
    point-prevalence abstinence defined as not smoking in the previous seven days based on self-report and confirmed with a Carbon Monoxide (CO) level ≤ 8 ppm

  5. Stimulant-free Results at 6-month Visit [ Time Frame: 6 - months follow-up visit ]
    At the 6-month follow-up visit, percentage of participants with a negative urine drug screen for stimulant use and no stimulant use days reported during the past 28 days based on Timeline Follow-back.

  6. Point-prevalence Abstinence (Smoking Outcome) 6 Month Visit [ Time Frame: 6 month visit ]
    point-prevalence abstinence defined as not smoking in the previous seven days based on self-report and confirmed with a Carbon Monoxide (CO) level ≤ 8 ppm
