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.
