Scroll Down and see who FDA took a Shot at and only (3) within the Hemp Play Quote: The agency has warned companies that CBD is not currently legal to add to food, drinks, or supplements. This spring, the FDA sent out warning shots to three companies in violation of current CBD guidelines; New Jersey’s Advanced Spine and Pain LLC, Washington’s Nutra Pure LLC, and Florida’s PotNetwork Holdings Inc. The warnings were based on unsubstantiated health claims that the brands had been making. It was far from the first time the agency had made such a move, but perhaps the most well-known incident since federal hemp legalization.
