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

The law in Oklahoma

Oklahoma's agriculture law, 2 O.S. 3-402, defines industrial hemp by total delta-9 THC: no more than 0.3 percent on a dry weight basis. The Department of Agriculture's rule requires testing after decarboxylation, so results count THCA, and its January 16, 2026 letter says hemp products may hold no more than 0.3 percent total THC, measured as THC plus 87.7 percent of THCA.

SB 1257 brought the controlled substances act into line. Signed May 20, 2026 and in force since November 1, 2026, it leaves hemp out of the definition of marijuana only when its combined delta-9 THC and THCA is no more than 0.3 percent, measured after decarboxylation.

1. November 1, 2019Hemp products may be sold at retail without a license; CBD in food is permitted.
2. November 1, 2021The Oklahoma Kratom Consumer Protection Act takes effect.
3. January 16, 2026The Department of Agriculture restates the 0.3% total THC limit for hemp products.
4. May 20, 2026SB 1257 is signed, counting THCA in the hemp line and moving THC to Schedule I.
5. November 1, 2026SB 1257 takes effect.
6. December 11, 2026The federal limit of 0.4 mg total THC per container begins.

What SB 1257 changed

SB 1257 also widened the definition of marijuana to cover tetrahydrocannabinols and their acids, including synthetic equivalents and isomers with similar structure and effect, and moved tetrahydrocannabinols from Schedule III to Schedule I. Oklahoma's definition of tetrahydrocannabinols already named those derived from industrial hemp.

The act sets no milligram limit, age limit or retail license for hemp-derived THC, and it does not say in words whether a given delta-8 product is now marijuana. We found no court ruling or Attorney General opinion on that question. A July 12, 2025 emergency rule of the Oklahoma Medical Marijuana Authority left delta-8 and delta-10 hemp products out of its own definition of marijuana.

Selling hemp and CBD

Under 63 O.S. 1-1431, hemp products may be sold at retail without a license, as long as the hemp was grown legally. Adding hemp-derived CBD to cosmetics, personal care products and foods for people or animals is permitted and is not an adulteration. Food safety laws still apply.

Any manufactured product with CBD must be labeled with the country of origin of the CBD and whether it is synthetic or natural. Growers, processors and handlers need Department of Agriculture licenses, and the controlled substances act says qualifying hemp may be shipped within the state and between states.

Bills that did not pass

Two 2026 bills on hemp drinks got close. HB 4248, an age of 21 for hemp beverages, passed both chambers, but on May 6, 2026 it was recalled from enrollment. SB 3, rewritten in the House to adopt the federal definition, a 0.4 mg total THC limit per container and an age of 21 for hemp drinks sold in package stores, passed the House on April 29, 2026 and went no further. Oklahoma sets no minimum age for hemp or CBD products.

Kratom, kava, amanita and spores

The Oklahoma Kratom Consumer Protection Act, in force since November 1, 2021 and last amended in 2025, bars selling kratom products to anyone under 18, caps 7-hydroxymitragynine at 1 percent of total kratom alkaloids, bars synthesized alkaloids and requires labels with alkaloid amounts and a warning. Kratom is not in Schedule I.

We found no Oklahoma statute naming kava, amanita muscaria or its compounds, or mushroom spores. Psilocybin and psilocyn are Schedule I.
