Sex differences in plasma, adipose tissue, and central accumulation of cannabinoids, and behavioural effects of oral cannabis consumption in male and female C57BL/6 mice.

BACKGROUND: Cannabis edibles are an increasingly popular form of cannabis consumption. Oral consumption of cannabis has distinct physiological and behavioural effects than injection or inhalation. An animal model is needed to understand the pharmacokinetics and physiological effects of oral cannabis consumption in rodents as a model for human cannabis edible use.

METHODS: Adult male and female C57BL/6 mice received a single dose of commercially available cannabis oil (5 mg/kg THC) by oral gavage. At 0.5-, 1-, 2-, 3-, and 6-hours post-exposure, plasma, hippocampus, and adipose tissue was collected for THC, 11-OH-THC, and THC-COOH measures.

RESULTS: We report delayed time to peak THC and 11-OH-THC concentrations in plasma, brain and adipose tissue, which is consistent with human pharmacokinetics studies. We also found sex differences in the cannabis tetrad: (1) female mice had a delayed hypothermic effect 6 hours post-consumption, which was not present in males; (2) females had stronger catalepsy than males; (3) males were less mobile following cannabis exposure, whereas female mice showed no difference in locomotion but an anxiogenic effect at 3h post exposure; and (4) male mice displayed a longer lasting antinociceptive effect of oral cannabis.

CONCLUSIONS: Oral cannabis consumption is a translationally relevant form of administration that produces similar physiological effects as injection or vaping administration and thus should be considered as a viable approach for examining the physiological effects of cannabis moving forward. Furthermore, given the strong sex differences in metabolism of oral cannabis, these factors should be carefully considered when designing animal studies on the effects of cannabis.
