Cannabis and its primary psychoactive component, THC, acutely alter executive, emotional, reward, and memory processing by directly interacting with the endocannabinoid system and indirectly affecting glutamatergic, GABAergic, and dopaminergic systems. Cannabidiol, a non-intoxicating cannabinoid, may offset some of these acute effects. Heavy repeated cannabis use, especially during adolescence, is associated with adverse effects that increase the risk of mental illnesses such as addiction and psychosis. This review synthesizes human neuroimaging research on the acute and chronic neuropsychopharmacology of cannabis, covering effects during development, implications for psychosis and cannabis use disorder, and methodological considerations.
