In general, hemp-derived beverages that contain artificially derived cannabinoids are prohibited from being sold in Oregon. The only exception to this rule is if the artificially derived cannabinoid has been approved for sale by the OLCC. Cannabinoids that are sometimes manufactured as artificially derived cannabinoids include delta-9-THC, delta-8-THC, CBN, HHC, and THCO. However, some of these cannabinoids (e.g. delta-9-THC, CBN) can also occur naturally in hemp. Whether a product containing these cannabinoids is eligible for sale to Oregon consumers depends on how the cannabinoids were made.
