Morphine addiction in non-human primates using rhesus monkeys
恒河猕猴吗啡成瘾模型的初步建立

We showed that rhesus monkeys (Macaca mulatta) can develop a morphine dependence. Rhesus monkeys successfully established a conditioned place preference (CPP) induced by morphine treatment and this preference lasted for at least (36.3±1.3) months. This animal model may be useful for research into addiction in humans.
