Evaluation of conditioned place preference for cocaine in wild-type (WT) and CB₂r overexpressing (CB₂xP) mice. Columns represent the mean and vertical lines + SEM of time spent in the cocaine conditioned compartment by WT (n=8) and CB₂xP (n=8) mice, expressed as percentage of total time. ^*P<0.05 vs WT mice.
