Intravenous clonidine self-administration was studied in rhesus monkeys under conditions of limited and unlimited access. Limited access consisted of daily 2-h experimental sessions with drug available on a fixed ratio 10 schedule. For unlimited access, drug was available 23 h/day with each response

Scheduled infusions of naloxone (1-100 micrograms/kg/inf.) and of buprenorphine (250 micrograms/kg/inf.) generated drug avoidance behavior in the non-dependent rhesus monkey under a continuous avoidance-escape paradigm. Pentazocine (1-100 micrograms/kg/inf.) codeine, (1-100 micrograms/kg/inf. and ti
Diazepam self-administration was studied in rhesus monkeys under several conditions of availability. Leverpress responding was maintained in twelve monkeys under a fixed-ratio 10 (FR 10) schedule of IV cocaine or pentobarbital delivery in daily sessions of 1-3 h duration. Each of several doses of di
l%hesus monkeys were conditioned to press a key to selfadminister intravenous injections of either cocaine (8 monkeys) or codeine (7 monkeys). Every tenth lever press resulted in an injection of 50 mcg/kg/inj, cocaine or codeine during daily 3 h sessions. Equal doses of cocaine and codeine generated
