The active, chemical ingredients of cannabis are called cannabinoids, which include Tetrahydrocannabinol (THC, a psychoactive), and Cannabidiol (CBD), which boost the positive effects of the body’s innate cannabinoids. The ratio of THC to CBC will differ from cannabis product to product, depending on what the product is, and/or who is producing it. Remember to only acquire medical cannabis products from licensed producers and distributors.
