The effects of cannabinoids on body temperature and brain catecholamine synthesis

delta9-Tetrahydrocannabinol, 11-OH-delta9-tetrahydrocannabinol and 9-nor-9beta-OH-hexahydrocannabinol produced hypothermia and increased catecholamine synthesis in mouse brain. The potencies of the effects of these compounds were correlated. Cannabinol and cannabidiol were inactive in both tests.
