When it comes to HHC’s legal status, it is not as straight as that of THC or CBD. The consensus among those in the know is that, as per the United States’ 2018 Farm Bill, HHC is legal on a federal level. The key points here are that the HHC must be derived from the hemp plant — not marijuana — and the final product cannot contain more than 0.3% delta-9-tetrahydrocannabinol (THC) by dry weight. THC is the compound in cannabis that makes people “high.”
