Is THCA Legal in North Dakota?

Last reviewed: May 22, 2026

No. North Dakota measures hemp on a total-THC basis under N.D. Cent. Code chapter 4.1-18.1. The formula (THCA x 0.877) + delta-9 THC must remain at or below 0.3% by dry weight, which captures THCA flower sold at retail potency. THCA products are not lawful at North Dakota hemp retail.

North Dakota cannabis and hemp overview

North Dakota voters approved medical cannabis through Measure 5 in 2016, codified as the Compassionate Care Act. Adult-use ballot measures failed in 2018, 2022, and 2024. The Department of Health and Human Services runs the medical program, and the North Dakota Department of Agriculture administers industrial hemp under N.D. Cent. Code chapter 4.1-18.1.

The 67th Legislative Assembly passed HB 1045 in 2021, which redefined THC to include delta-9 plus any structural, optical, or geometric isomers and prohibited isomerization of CBD into THC. The 68th Legislative Assembly tightened the framework further with SB 2096, signed April 24, 2023, which excluded delta-8 THC products from the statutory hemp definition.

What North Dakota law actually says about THCA

The state defines industrial hemp using a total-THC reading rather than a delta-9-only test. Total THC equals (THCA x 0.877) + delta-9 THC, measured on a dry-weight basis. Hemp must stay at or below 0.3% total THC.

THCA-rich flower marketed at 15% to 25% potency does not satisfy that test. Once the THCA percentage is multiplied by 0.877 and added to delta-9 THC, the finished flower exceeds 0.3% by an order of magnitude. The North Dakota Department of Agriculture treats those products as marijuana under state law, not as compliant hemp.

How enforcement has played out

North Dakota has been an early enforcer against intoxicating hemp. Attorney General Drew Wrigley announced a 2023 settlement with delta-8 resellers over illegal vape sales, including sales to minors, resulting in a one-year suspension of shipments into the state and mandatory age-verification thereafter. The Department of Agriculture has issued guidance reiterating that THC isomers fall outside the hemp definition under state law.

What this means for retailers selling THCA in North Dakota

• Do not stock smokable THCA flower, dabs, or concentrates intended for combustion or vaporization.
• Pull any product that fails the total-THC formula on finished-product testing.
• Treat upstream certificates of analysis that report only delta-9 as insufficient documentation for North Dakota.
• Verify identification and age at point of sale; medical cannabis is dispensary-only.
• Plan for federal H.R. 5371 section 781, which takes effect November 12, 2026, and caps finished hemp products at 0.4 mg total THC per container.

What this means for consumers buying THCA in North Dakota

THCA flower is not lawfully available at North Dakota hemp retail. Qualifying patients can access medical cannabis through licensed dispensaries under the Compassionate Care Act and HB 1203 (2025), which added lozenge edibles capped at 5 mg per serving and 50 mg per package. Possession limits and the registry requirement still apply. THCA converts to delta-9 THC when heated, so any product consumed by smoking, vaping, or baking will trigger a positive on standard drug tests.

Pending legislation to watch

Federal H.R. 5371 section 781 was signed November 12, 2025, and takes effect November 12, 2026. It moves the federal hemp definition to a post-decarboxylation total-THC standard, caps finished hemp products at 0.4 mg total THC per container, and excludes synthetic or converted cannabinoids. North Dakota already applies a total-THC reading, so the federal change will reinforce rather than alter the state position on THCA.

Frequently asked questions

Is THCA flower legal in North Dakota?
No. The state uses a total-THC formula that captures THCA before combustion. Retail-potency THCA flower exceeds the 0.3% cap.

How does North Dakota calculate total THC?
(THCA x 0.877) + delta-9 THC, dry weight. Hemp must stay at or below 0.3% under that formula.

Can I buy THCA through the medical program?
The Compassionate Care Act covers medical cannabis flower and lozenge edibles dispensed by licensed providers. Out-of-network THCA products are not part of that program.

Does THCA show up on a drug test?
Yes once heated. Combustion or decarboxylation converts THCA to delta-9 THC, which standard urine screens detect.

What about shipping THCA into North Dakota?
Inbound shipments are subject to seizure and the Attorney General has previously settled enforcement cases against out-of-state sellers.

How will federal H.R. 5371 affect North Dakota?
The federal change effective November 12, 2026, reinforces the state total-THC approach and adds the 0.4 mg per container cap.
