CBD comes from both industrial hemp and cannabis. Both products see different regulations. The CBD from cannabis regulates as a cannabis product and only people with a commercial cannabis license can source, produce, and supply it. This CBD is not an approved food additive. Marijuana contains more percentage of THC than it does of CBD and is hence not a great addition to food items.
CBD derived from industrial hemp, on the other hand, is safer to use as a food additive, diet and beauty supplement, and as a medicine.
