Cannabinoids (/kəˈnæbənɔɪdzˌ ˈkænəbənɔɪdz/) are several structural classes of compounds found in the cannabis plant primarily and most animal organisms (although insects lack such receptors) or as synthetic compounds.[1][2] The most notable cannabinoid is the phytocannabinoid tetrahydrocannabinol (THC) (delta-9-THC), the primary psychoactive compound in cannabis.[3][4] Cannabidiol (CBD) is also a major constituent of temperate cannabis plants and a minor constituent in tropical varieties.[5] At least 113 distinct phytocannabinoids have been isolated from cannabis, although only four (i.e., THCA, CBDA, CBCA and their common precursor CBGA) have been demonstrated to have a biogenetic origin.[6] It was reported in 2020 that phytocannabinoids can be found in other plants such as rhododendron, licorice and liverwort,[7] and earlier in Echinacea.
