Objective: In recent years cannabinoids and their use have attracted a great deal of attention. The aim of the present examination is to study the effect of the cannabinoid system and its interaction with the opioid system in state-dependent memory.
Method: In this experimental study, the intracerebroventricular (ICV) administration of different doses of cannabinoid agonists and antagonists, and the subcutaneous administration of morphine was used in the passive avoidance task.
Results: Cannabinoid agonists prevent the retrieval of memory by morphine.
Conclusion: The improvement of retrieval memory by morphine treatment seems to be induced, at least in part, through the cannabinoid receptors.
