DistributionAfter absorption, the blood circulation transports compounds, such as THC, to the body’s organs. This phase in pharmacokinetics is called distribution. Since THC is very lipophilic, i.e. fat-loving in nature, THC and its metabolites rapidly distribute to fatty tissues, such as the brain.1, 2 Due to this lipophilicity, THC is accumulated and stored in the body fat where it is slowly released back into the blood.3 References:
