Effects of meperidine on operant behavioral thermoregulation in mice under conditions of symmetrical thermal drive.

abstract：RATIONALE:Cocaine and opioids are often co-abused. As yet, however, there is no clear evidence that the drugs interact to make the mixture a more effective reinforcer. OBJECTIVE:The present study examined the relative reinforcing potency and maximum effectiveness of the cocaine-opioid combination in monkeys given a ch...
