Includes THC, Terpenes and Flavonoids. A full-spectrum extract contains all the compounds from the plant that naturally occur in it. This includes the cannabinoids (including CBD), terpenes, flavonoids, and essential oils. All these compounds work in concert to produce the “entourage effect”. Be aware that THC has not been removed from full-spectrum hemp extracts and could cause a positive drug test if enough oil is consumed,Broad-spectrum is all the above except the THC has been removed to the extent that it is undetectable; thus, there is no psychoactive component to a broad spectrum extract that would get your pet “high”.
