Effects of rimonabant given as a pretreatment before experimental session on responding maintained by 2-AG (A), THC (B), or food (C) during five consecutive sessions. A–C, Numbers of injections per session after intramuscular pretreatment with vehicle (sessions 1–3 and 9–11, closed circles,) or 0.3 mg/kg rimonabant (sessions 4–8, open circles) are shown. Each point represents the mean ± SEM from three (A), five (B), or four (C) monkeys. **p < 0.01, post hoc comparisons with the last session with vehicle pretreatment (session 3) before pretreatment with rimonabant.
