Cannabinoids are the active ingredients, or ingredients that trigger a biological response, found in cannabis plants. To date, over 100 types of cannabinoids have been identified, and these compounds are not produced by cannabis alone. Some are produced by other plants, some are found in the human body, and they’ve also been replicated in a laboratory for use in a variety of prescription medications. Two of the most well known cannabinoids in cannabis are THC and CBD.
