The first cannabinoid receptor is a cannabinoid receptor that is found primarily in the central nervous system, where it mediates retrograde neurotransmission.[1] It is believed to be the single most abundant receptor in the human brain. It also exerts effects on reproduction, in both sexes. It inhibits sperm motility.[2] Its mediates the psychoactive effects of cannabinoids, along with their effects on fertility. It is a metabotropic receptor, that has an inhibitory effect on neuronal activity.[3][4] It inhibits the release of neurotransmitters (including glutamate, dopamine, acetylcholine, noradrenaline, histamine, etc.), while also, indirectly, inducing the release of others like noradrenaline, dopamine in certain brain regions via its inhibitory influence on GABAergic interneurons.[1][4][5] Its endogenous ligands are endocannabinoids anandamide and 2-arachidonoylglycerol.[5]
