Many people believe cannabis will be “out of their system” in weeks. However, that isn’t always the case.
Unlike alcohol or caffeine, tetrahydrocannabinol (THC), the primary psychoactive compound found in cannabis, doesn’t clear from the bloodstream in a few hours; it accumulates in fat and organs, where it can continue influencing inflammation and immunity long after the high fades.
For occasional users, its lingering presence may not matter much. However, with today’s high-potency products and increasingly frequent use, researchers are discovering that the body’s relationship with cannabis has fundamentally changed—and the long-term effects of accumulation are only beginning to come into focus.
