∆THC-P Many of us have heard about cannabinoids like THC or CBD in the hemp or cannabis plant, but have you heard about one of the most recently discovered cannabinoids, THC-P? Tetrahydrocannabiphorol or THC-P is a cannabinoid that exists only in very trace amounts inside of a cannabis plant like hemp’s chemical structure. THC-P is unique in that it works on CB1 receptors at about 31 times the rate of THC. That’s some impressive bioavailability right there. THC-P is very new in terms of our awareness of it, too.
