Cannabinoid
A class of compounds that interact with the endocannabinoid system — includes plant-derived (THC, CBD), synthetic, and endogenous forms.
Cannabinoids are compounds — plant-derived (phytocannabinoids), synthetic, or produced by the human body (endocannabinoids) — that interact with cannabinoid receptors, primarily CB1 (central nervous system) and CB2 (peripheral immune system). In medical contexts, the term most often refers to THC, CBD, and their structural analogues. Clinical formulations vary in cannabinoid ratio and delivery form (oil, capsule, oromucosal spray, inhaled flower), each with distinct pharmacokinetic profiles that influence onset, peak, and duration of effect.
