THC and CBD are both forms of cannabinoids, or active ingredients, that are found in cannabis. THC (delta-9-Tetrahydrocannabinol) is one of the most prominent cannabinoids found in the cannabis plant, and has intoxicating and other pharmacological effects on the human body. Another abundant active ingredient in cannabis is CBD (cannabidiol), a non-intoxicating cannabinoid. It does not have the same noted effects as THC, and may counterbalance some of THC’s effects.
