There’s a lot of science behind understanding cannabis, but we’ll do our best to simplify it: Cannabis is made up of more than 120 components, which are known as cannabinoids. Cannabidiol (CBD) and tetrahydrocannabinol (THC), are the two most well-known and researched cannabinoids. THC is responsible for the “high” that many people associate with cannabis, while CBD is a non-intoxicating, non-euphoric component, which you may have seen in the form of oils, gummies, drinks and other products for medical purposes.
