Abstract

Pharmacological effects (catalepsy, hypothermia, pentobarbital-induced sleep prolongation, anticonvulsant and analgesic effects) of Δ⁸- and Δ⁹-tetrahydrocannabinols, and their 11-hydroxy-metabolites were evaluated and compared in mice. Δ⁹-Tetrahydrocannabinol and 11-hydroxy-Δ⁹-tetrahydrocannabinol exhibited somewhat greater effects than did Δ⁸-tetrahydrocannabinol and 11-hydroxy-Δ⁸-tetrahydrocannabinol, respectively, in all pharmacological indices tested. Greater effects of 11-hydroxy-metabolites than those of tetrahydrocannabinols were also demonstrated.
