Abstract

Rats trained in conditioned avoidance responding (CAR) after injections of either 7.5 mg/kg Δ9-THC (tetrahydrocannabinol) or 15 mg/kg Δ8-THC, showed no transfer when tested in the non-drugged state. Furthermore, these doses of the isomeric tetrahydrocannabinols exerted a disruptive effect on previously established CAR in rats, trained under normal conditions.

Only the Δ9-THC-group showed an impairment of acquisition which was statistically significant compared to the control group.
