In this behavioral trial 120 methadone maintained cocaine abusing individuals will be randomly assigned to either treatment as usual in a community-based clinic OR treatment as usual plus 8 hours of access to the 'CBT for CBT' computer program over a period of 8 weeks. Primary outcomes will be retention in treatment and reduction in cocaine use (percent days abstinent, confirmed by urine toxicology screens). The patients' ability to demonstrate coping skills through a computerized role-play evaluation will be a secondary outcome. A six-month follow-up will assess durability and/or delayed emergence of effects.
