Is Hemp-Derived Delta-9 THC Legal in Washington?

Last reviewed: May 22, 2026

Restricted. Hemp-derived delta-9 THC edibles, beverages, and tinctures are treated as cannabis products under Washington law and may only be sold by WSLCB-licensed cannabis retailers to adults 21 and over. SB 5367 (2023) closed the federal Farm Bill workaround that some other states still allow for "compliant" delta-9 hemp products. There is no general-retail tier for delta-9 hemp gummies or seltzers in Washington.

Washington Cannabis & Hemp Overview

The Washington State Liquor and Cannabis Board (WSLCB) regulates licensed cannabis under RCW Chapter 69.50, the state's Uniform Controlled Substances Act, and Initiative 502 (2012). The Washington State Department of Agriculture (WSDA) administers hemp cultivation under RCW Chapter 15.140 (the Washington Hemp Production Act). Adults 21 and over may possess up to 1 ounce of useable cannabis, 16 ounces of cannabis-infused solid product, 72 ounces of cannabis-infused liquid, and 7 grams of concentrate under RCW 69.50.360 and RCW 69.50.4013.

The federal Farm Bill (2018) defined hemp as Cannabis sativa with delta-9 THC at or below 0.3 percent on a dry-weight basis. That definition opened a national market for hemp-derived delta-9 products that meet the percentage threshold by weight: large gummies, beverages, and chocolates that each contain 5 to 10 mg of delta-9 while staying under 0.3 percent by total product weight. Several states allow those products at general retail with potency caps. Washington does not.

What Washington Law Actually Says

SB 5367 (2023), signed by Governor Inslee on May 9, 2023 and effective July 23, 2023, amended the RCW 69.50 definition of "cannabis product" to include any product with detectable THC. The bill removed the prior delta-9-only language from "THC concentration." A 5 mg delta-9 hemp gummy that meets the federal 0.3 percent by weight test still contains detectable delta-9 THC, which places it inside the Washington cannabis product definition.

Cannabis products under RCW 69.50 may only be sold by WSLCB-licensed cannabis retailers to adults 21 and over. They must be tracked in WSLCB traceability and labeled with the post-decarboxylation total THC figure. WSLCB-licensed retailers may stock hemp-derived delta-9 edibles only if the manufacturer holds an appropriate WSLCB cannabis processor license; in practice, the existing licensed processor base supplies the cannabis edibles channel directly, and a separate hemp-edible path is not in use.

WSDA hemp licensees grow industrial hemp under the federal delta-9-only field standard. The Farm Bill cultivation rule and the state retail rule are separate; complying with one does not mean compliance with the other.

How Enforcement Has Played Out

WSLCB has issued cease-and-desist letters to convenience stores, grocery stores, and beverage distributors that stocked hemp-derived delta-9 seltzers and gummies after SB 5367 took effect. Some out-of-state online retailers continue to ship delta-9 hemp products to Washington addresses, and WSLCB has coordinated with local law enforcement and the Attorney General's office on stop-sale and seizure actions. Cannabis licensees that source non-WSLCB-traced delta-9 product face license revocation.

What This Means for Retailers Selling Hemp Delta-9 in Washington

• Hold an active WSLCB cannabis retailer license to sell any product with detectable delta-9 THC, including federally compliant hemp-derived edibles and beverages.
• Source product from WSLCB-licensed processors. The hemp-edible-via-Farm-Bill path is not recognized at retail in Washington.
• Track product in WSLCB traceability. Labeling must show post-decarboxylation total THC.
• Convenience stores, grocery stores, and bars and restaurants cannot stock delta-9 hemp seltzers or gummies without a WSLCB cannabis retailer license.
• Watch H.R. 5371 §781. The federal redefinition takes effect November 12, 2026 and applies the same total-THC math at the federal level.

What This Means for Consumers Buying Hemp Delta-9 in Washington

You can buy hemp-derived or cannabis-derived delta-9 edibles and beverages from a WSLCB-licensed cannabis retailer if you are 21 or older. You cannot buy delta-9 hemp seltzers, gummies, or chocolates at grocery stores, gas stations, or smoke shops in Washington. Out-of-state shipments of delta-9 hemp products to Washington addresses violate SB 5367. Hemp-derived delta-9 is chemically identical to marijuana-derived delta-9 and produces the same drug test result.

Pending Legislation to Watch

The federal hemp redefinition in H.R. 5371 §781, signed November 12, 2025 and effective November 12, 2026, replaces the delta-9-only standard with post-decarboxylation total-THC testing and caps finished hemp products at 0.4 mg total THC per container. The federal cap is well below the typical 5 to 10 mg delta-9 hemp serving sold in permissive states today. Washington's SB 5367 already reaches that result through its detectable-THC standard.

Frequently Asked Questions

Is hemp-derived delta-9 THC legal in Washington in 2026? Restricted. SB 5367 (2023) treats any product with detectable THC as a cannabis product, which limits hemp delta-9 retail to WSLCB-licensed cannabis stores serving adults 21 and over.

What is the difference between hemp delta-9 and cannabis delta-9? Chemically they are the same molecule. The federal distinction is the source plant and the 0.3 percent by dry-weight cultivation test. Washington's SB 5367 retail standard treats the molecule the same regardless of source.

Can I buy delta-9 hemp seltzers at a Washington grocery store? No. Detectable delta-9 in a beverage makes it a cannabis product under SB 5367, and grocery stores are not WSLCB-licensed cannabis retailers.

Does hemp-derived delta-9 show up on a drug test? Yes. Hemp-derived delta-9 and cannabis-derived delta-9 produce identical metabolites and will trigger a positive on standard urine, saliva, and hair screens.

Can I order delta-9 hemp edibles online to a Washington address? Out-of-state shipments of delta-9 products to Washington addresses violate SB 5367 and may be intercepted by WSLCB or local enforcement.

What changes for hemp delta-9 nationally on November 12, 2026? The federal hemp redefinition replaces the delta-9-only test with post-decarboxylation total THC and caps finished hemp products at 0.4 mg per container, ending most of the federal-Farm-Bill-compliant 5 mg and 10 mg delta-9 hemp product line.

How does Washington compare to permissive states like Minnesota or Florida? Washington's framework is significantly stricter. Permissive states allow capped hemp-derived delta-9 at general retail; Washington routes it through the WSLCB cannabis system entirely.
