“Ethanol and morphine are largely co-abused and affect memory formation.
The present study intended to investigate the involvement of cannabinoid CB1 receptors of the basolateral amygdala (BLA) in cross state-dependent memory retrieval between morphine and ethanol.
Taken together, it can be concluded that morphine and ethanol can induce state-dependent memory retrieval.
In addition, the BLA endocannabinoid system mediates via CB1 receptors the functional interaction of morphine and ethanol state-dependent memory retrieval which may depend on the rewarding effects of the drugs.”
