Cannabidiol (CBD) is derived from cannabis flowers and buds (marijuana or hemp plants). CBD, on the other hand, does not generate the “high” associated with marijuana since it lacks the chemical tetrahydrocannabinol (THC).
To be clear, hemp and marijuana are both derived from the cannabis plant, but they contain varying amounts of THC. Marijuana can contain up to 30% THC, but hemp has no more than 0.3 percent THC. While marijuana-derived CBD oil is still banned in the majority of states, hemp-derived CBD oil is lawful in all 50 states.
