Tissue levels of 3H were higher 2 hr after oral administration of 3H-delta9-THC (10 mg/kg in sesame oil) to male Fischer rats in the morning compared with treatment in the afternoon. A corresponding reduction in potency was seen for the impairing effect of delta9-THC on performance of a conditioned avoidance response (CAR). The hypothesis that these effects were related to the interval between feeding (which normally occurs during the night in the nocturnal rat) and drug administration was supported when they were mimicked in overnight fasted and ad lib fed rats. Food deprivation decreased the rate of gastrointestinal absorption of 14C-delta9-THC in sesame oil. Peak plasma levels of 14C occurred 2-4 hr after administration in fed rats compared with 8 hr in fasted rats. When tested 2 hr after oral administration, delta9-THC caused significantly greater impairment of CAR performance in fed than fasted rats, whereas the opposite was found after 8 hr. Extraction and subsequent thin layer chromatography of plasma and brain from fed and fasted rats sacrificed 2 or 8 hr after oral administration of 10 mg/kg 14C-delta9-THC showed that brain levels of 11-hydroxy-delta9-THC rather than delta9-THC were correlated with the behavioral effect.
