EFFECTS OF ETHANOL ON COCAINE SELF-ADMINISTRATION IN MONKEYS RESPONDING UNDER A SECOND-ORDER SCHEDULE OF REINFORCEMENT

摘要

BackgroundConcurrent alcohol use among cocaine abusers is common but the behavioral variables that promote co-abuse are not well understood. The present study examined the effects of intragastric (i.g.) ethanol (EtOH) administration in monkeys responding under a schedule of cocaine reinforcement in which extensive drug seeking was maintained by conditioned stimuli.
