The term cannabinoid describes any chemical that acts on cannabinoid receptors in the brain and body (endocannabinoid system). There are several different types of cannabinoids, such as endocannabinoids, phytocannabinoids, and synthetic cannabinoids.
Endocannabinoids are cannabinoids that are naturally synthesized in the human body, such as anandamide (the bliss molecule).
Phytocannabinoids are cannabinoids found in plants, such as cannabidiol (CBD), delta-9-tetrahydrocannabinol (THC), cannabigerol (CBG) and many more.
Synthetic cannabinoids are man-made chemicals that mimic natural cannabinoids, and research suggest much higher doses are required.
