Reinstatement of extinguished (Ext) anandamide (AEA, a), Δ9-tetrahydrocannabinol (THC) (b), or cocaine (c) seeking behavior by priming injections of THC (40 µg/kg, i.v.) (gray bars), but not by vehicle (V, empty bars) or URB597 (0.3 mg/kg, i.v.) (URB, solid bars). Data are mean ± SEM from 3–5 monkeys over three sessions under each condition. Single-factor ANOVA for repeated measures, post-hoc comparisons (Bonferroni t-test) vs. vehicle pretreatment: **p < 0.01.
