Is THCA legal in Oregon? Oregon hemp, CBD and kratom laws

The law in Oregon

Oregon splits hemp oversight between two agencies. The State Department of Agriculture licenses growers and handlers under ORS 571.260 to 571.348 and sets the THC concentration that defines industrial hemp by rule. The Oregon Liquor and Cannabis Commission, which also runs the adult-use marijuana market, sets the THC limits for hemp products sold to consumers and, since January 1, 2026, keeps the registry every cannabinoid hemp product must be on before it reaches an Oregon buyer.

The key idea in Oregon law is the "adult use cannabinoid." ORS 475C.009 defines it to include tetrahydrocannabinols and tetrahydrocannabinolic acids, natural or artificial, delta-8 THC, delta-9 THC and any artificially derived cannabinoid reasonably determined to be intoxicating. A hemp product past the commission's limit for those compounds, or past 0.3 percent total delta-9 THC, counts as a marijuana item, and ORS 475C.257 lets only a licensed marijuana retailer sell a marijuana item to a consumer.

1. July 19, 2021The Governor approves HB 3000, which defines adult use cannabinoids, THCA included, and takes effect on passage.
2. January 1, 2022The OLCC rule setting the 0.5 mg adult use line for hemp items, OAR 845-026-0300, takes effect.
3. July 1, 2023The Oregon Kratom Consumer Protection Act, 2022 chapter 41, becomes operative.
4. March 20, 2024The Governor approves HB 4121, which creates the OLCC registration program for hemp products.
5. October 22, 2024The OLCC limits of 2 mg total delta-9 THC a serving and 20 mg a package take effect.
6. January 1, 2026Hemp product registration with the OLCC becomes operative.
7. December 11, 2026The federal limit of 0.4 mg total THC per container begins.

THCA and delta-8

Under OAR 845-026-0300, a hemp item is an adult use cannabis item if it holds 0.5 mg or more of total delta-9 THC, 0.5 mg or more of any other THC or THCA, delta-8 included, any cannabinoid the seller advertises as intoxicating, or any amount of an artificially derived cannabinoid. The same rule applies when the lab method cannot show the item is under 0.5 mg. An adult use cannabis item may not be sold or delivered to anyone under 21, and the commission may fine a seller up to $10,000 a violation.

Oregon's testing rule, OAR 333-064-0100, calculates total delta-9 THC as delta-9 THC plus 0.877 times the delta-9 THCA, so THCA counts against every limit. OAR 845-026-0400 and its Table 3 cap usable hemp, concentrates and extracts at 0.3 percent total delta-9 THC, and edibles, patches and other products at 2 mg a serving and 20 mg a package; tinctures may hold 100 mg a package.

An artificially derived cannabinoid is one made by a chemical reaction that changes its molecular structure, which leaves out THC formed from THCA by heat alone. A hemp product may contain one only if it is not a controlled substance, the commission judges it not impairing or intoxicating at the intended concentration, it has been reported as natural to the cannabis plant in at least three peer-reviewed publications, the product is not for inhalation, and its maker holds a GRAS determination or a qualifying FDA letter (OAR 845-026-0400 and 845-026-0415).

Age, registration and labels

ORS 571.295, added by HB 4121, requires the person responsible for making, packaging or distributing a hemp product with cannabinoids, whether in Oregon or elsewhere, to register it with the commission every year before it is sold to an Oregon consumer or retailer. The application carries a certificate of analysis, a copy of the label and a statement of whether the product is an adult use cannabis item, and ORS 571.296 bars selling an unregistered product. Products meant only for topical use, hemp grain and fiber products with no added cannabinoids, and registered animal feeds are exempt.

The label must show the product name and type, the maker's name and address, the ingredients, the net weight, the serving size and servings, the potency and cannabinoid contents, and a web address for the certificate of analysis. An adult use cannabis item must also read "For use only by adults 21 and older." and "Keep out of reach of children." ORS 571.296 also bars packaging that is attractive to minors, with cartoons or look-alike candy designs.

CBD in food and drinks

ORS 571.339 lets a hemp product meant for people be sold to a consumer only after testing by a laboratory licensed by the commission and accredited by the Oregon Health Authority, with the results kept on file. A product meant to be eaten must come from a food facility licensed by the State Department of Agriculture, or one in another state that meets substantially similar requirements, and when it is sold to anyone under 21 the test must show its delta-8 THC.

ORS 571.272 says the department may not consider hemp or hemp products an adulterant in food, while leaving it free to consider artificially derived cannabinoids adulterants.

Kratom, kava, amanita and spores

The Oregon Kratom Consumer Protection Act, 2022 chapter 41, became operative on July 1, 2023. It covers foods, supplements and drinks containing any part of the Mitragyna speciosa leaf: a retailer may not sell one to anyone under 21, a Class C misdemeanor for each violation, and a processor must register each year with the Department of Revenue, certifying third-party testing for adulteration, before selling to retailers. Oregon's Schedule I, OAR 855-080-0021, adopts the federal list as of April 1, 2025 and adds no kratom compound.

Oregon also licenses psilocybin services. Under the Oregon Psilocybin Services Act, ORS 475A.210 to 475A.722, the Oregon Health Authority licenses manufacturers and service centers, psilocybin products include psilocybin-producing fungi, and a licensee may not sell or deliver a psilocybin product to anyone under 21. We found no Oregon statute naming kava, amanita muscaria or mushroom spores.

The federal change on December 11
