β-PEA administration significantly induced conditioned place preference (CPP) in mice. (A) Experimental timeline for CPP test of β-PEA. (B,C) Time spent on the drug-paired side during the pre- (B) or post- (C) conditioning phase. (D) CPP score (post–pre) for β-PEA. * p < 0.05, ** p < 0.01 vs. saline-conditioned group. SAL, saline; β-PEA, β-phenylethylamine. n = 10 per group.
