Concurrent alcohol dependence among methadone-maintained cocaine abusers is associated with greater abstinence . Concurrent alcohol dependence ( AD ) among polysubstance abusers has been associated with negative consequences , although it may not necessarily lead to poor treatment outcomes . One of the most efficacious treatments for cocaine abuse is contingency management ( CM ) , but little research has explored the impact of AD on abstinence outcomes , particularly among patients in methadone maintenance . Using data from three trials of CM for cocaine use , we compared baseline characteristics and posttreatment and follow-up cocaine outcomes between methadone-maintained , cocaine-dependent patients ( N = 193 ) with and without concurrent AD , randomized to standard care ( SC ) with or without CM . Patients with and without concurrent AD had similar baseline characteristics , with the exception that AD patients reported more alcohol use . AD patients achieved longer durations of cocaine abstinence and were more likely to submit a cocaine-negative sample at follow-up than non-AD patients . Patients randomized to CM achieved better outcomes than those randomized to SC , but there was no interaction between treatment condition and AD status . These findings suggest that cocaine-using methadone patients with AD achieve greater cocaine abstinence than their non-AD counterparts and should not necessarily be viewed as more difficult to treat .
