Primary Outcome Measures:
- Number of participants who report cocaine use and have positive urine drug screens in the Chantix group versus the placebo group comparator [ Time Frame: Three times per week in weeks 2 through 13 ] [ Designated as safety issue: Yes ]Number of subjects with cocaine abstinence as measured through three-times-weekly urine benzoylecgonine (BE) levels in urine drug screen (UDS) and self-reports of use from the Time Line Follow Back. UDS results and TLFB reports combined to yield daily use/no-use indicators for each study day of treatment.
Secondary Outcome Measures:
- Number of participants who are compliant with taking medications in the Chantix group versus the placebo group comparator [ Time Frame: Three times per week during weeks 2 through 13 ] [ Designated as safety issue: No ]Measured through observed dosing at three-times-weekly clinic visits and weekly pill counts on the basis of self-reports and examination of blister packs.
- Number of participants who report cocaine craving in the Chantix group versus the placebo group comparator [ Time Frame: Once per week in weeks 2 through 13 ] [ Designated as safety issue: No ]As measured by weekly scores on the Cocaine Craving Questionnaire (CCQ) and the Minnesota Cocaine Craving Scale (MCC) during the medication treatment phase.
- Number of participants who have smoked cigarettes, both in isolation and in relation to cocaine use in the Chantix group versus the placebo group comparator. [ Time Frame: Once per week in weeks 2 through 13 ] [ Designated as safety issue: No ]Measured by carbon monoxide (CO) by CO monitor and cotinine levels using urinary cotinine dipstick testing at each clinic visit.
