Abstract

The effect of repetitive administration of delta-9-tetrahydrocannabinol (delta 9-THC) in mice on behavioral and biochemical tolerance was determined in this study. Mice were injected twice daily with 10 mg/kg delta 9-THC for 6.5 days. On day 8, spontaneous activity was assessed or whole-brain homogenates were prepared for the cannabinoid receptor binding and mRNA studies. Although a twenty-sevenfold tolerance to delta 9-THC was observed in the behavioral assay, there was no significant alteration in receptor binding or mRNA levels.
