Last Updated: August 6, 2026

Updated August 6, 2026: Texas status changed — after the Texas Supreme Court's May 1, 2026 Sky Marketing v. DSHS ruling, DSHS's Schedule I listing of non-delta-9 THCs took effect July 31, 2026 and Texas regulators treat THCA flower as prohibited. Tennessee's entry updated for the 2025 overhaul (THCA flower ban phased in during 2026).

Federal hemp law is two distinct things right now. The 2018 Farm Bill defined hemp by a single test: delta-9 THC at or under 0.3% on a dry-weight basis. That definition put THCA flower into a loophole — raw THCA tests low on delta-9 but converts to delta-9 the moment you apply heat. Eight years later, Congress closed that gap. H.R. 5371, signed November 12, 2025, rewrites the hemp definition in Section 781 to measure total THC after decarboxylation and caps any finished consumable at 0.4 milligrams of total THC per container. Section 781 takes effect November 12, 2026.

What that means for THCA flower is straightforward. Any flower or pre-roll that fails the post-decarb total-THC test on November 12, 2026 stops being hemp under federal law. It becomes Schedule I marijuana. States retain their own authority to regulate, ban, or permit hemp products independently — and several states have already moved to a total-THC or smokable-ban framework ahead of the federal deadline. The status table below reflects state law as of August 6, 2026. The deep-dive blocks below the table cover the five states drawing the highest THCA enforcement and search volume in 2026.

State-by-State THCA Status as of August 2026

Status definitions: Legal means THCA hemp products are permitted under current state law. Restricted means permitted with material conditions — total-THC testing, serving caps, license requirement, or product-form limits. Illegal means smokable THCA or all THCA is prohibited by statute or scheduled as a controlled substance. In flux means a TRO, pending appeal, or pending legislation is actively changing status.

State Answer Blocks

Is THCA Legal in Alabama (AL)?

No — smokable THCA is a Class C felony under HB 445 (effective July 1, 2025).

HB 445, signed by Governor Kay Ivey in May 2025, bans all smokable and inhalable hemp products — flower, pre-rolls, vapes, cartridges — and codifies the prohibition in Ala. Code § 13A-12-214.4 and § 28-12-2. Possession or sale of smokable THCA is a Class C felony carrying one to ten years and fines up to $15,000. Edibles and beverages remain legal but are capped at 10 mg total THC per serving and 40 mg per package, sold only through Alabama ABC Board licensees to buyers age 21 or older. The full licensing and labeling regime took effect January 1, 2026. No published appellate challenge to HB 445 is pending as of August 6, 2026.

Effective date: July 1, 2025 (smokable ban); January 1, 2026 (full licensing)

Is THCA Legal in Georgia (GA)?

Restricted — THCA flower is banned, extracts and most gummies are allowed.

SB 494, signed by Governor Brian Kemp in April 2024 and fully effective October 1, 2024, codifies a total-THC standard at O.C.G.A. § 2-23-3: total THC equals delta-9 plus 0.877 times THCA, and the product must test at or under 0.3% on a dry-weight basis. SB 494 also bans the retail sale of hemp flower and leaves regardless of cannabinoid content. Extracts, tinctures, and gummies meeting the total-THC cap remain legal; other hemp-infused food products are prohibited. The Georgia Department of Agriculture administers Chapter 2-23 and conducts retail inspections. No active litigation has overturned SB 494 as of August 6, 2026.

Effective date: October 1, 2024 (full SB 494 effect)

Is THCA Legal in North Carolina (NC)?

Yes — THCA is legal in North Carolina under SB 455 / SL 2022-32, which uses the federal Farm Bill 0.3% delta-9 threshold. No total-THC test, no state retailer license. HB 607 / Chapter 18D remains pending in House Rules.

SB 455 / Session Law 2022-32, signed by Governor Roy Cooper June 30, 2022, permanently excludes hemp-derived tetrahydrocannabinols from G.S. 90-94 of the NC Controlled Substances Act. North Carolina uses the federal Farm Bill 0.3% delta-9 dry-weight standard with no total-THC component, no per-serving milligram caps, and no retailer license. HB 607 would establish a Chapter 18D licensing framework with a $15,000 manufacturer license, ALE Division enforcement, 10 mg per serving / 100 mg per package edible caps, and accredited-lab COAs; it sits in House Rules (its proposed July 1, 2026 effective date passed unenacted) and retains the 0.3% delta-9 state threshold. The April 2026 NC Advisory Council on Cannabis Interim Report (Gov. Stein, EO 16) recommends adopting total-THC but has no force of law. UNC School of Government, Phil Dixon, Winter 2026 Cannabis Update: "state law in this area has not changed."

Effective date: Current standard effective since SL 2022-32, June 30, 2022.

Is THCA Legal in South Carolina (SC)?

Legal — THCA flower permitted under the Hemp Farming Act at S.C. Code § 46-55-10 et seq.

The South Carolina Hemp Farming Act, codified at S.C. Code § 46-55-10 et seq., defines hemp at 0.3% delta-9 THC on a dry-weight basis without an explicit total-THC component. The South Carolina Department of Agriculture administers cultivation licensing, and retail sale of hemp-derived products is generally permitted. The South Carolina Attorney General has issued opinions taking a strict stance on delta-8 and other isomers, but no opinion currently classifies THCA flower as a controlled substance when sourced from licensed hemp testing under 0.3% delta-9. The federal H.R. 5371 §781 total-THC rewrite effective November 12, 2026 is expected to materially constrain THCA flower sales in South Carolina even without a state law change.

Effective date: Hemp Farming Act effective 2019; current statutory text remains in force as of August 6, 2026

Is THCA Legal in Texas (TX)?

No — as of July 31, 2026, Texas regulators treat THCA flower as a prohibited Schedule I product. The injunction protection that carried retail THCA through spring 2026 ended after the Texas Supreme Court’s Sky Marketing Corp. v. DSHS ruling.

Judge Maya Guerra Gamble first granted a TRO on April 21, 2026 blocking the Texas Department of State Health Services’ rewrite of 25 TAC §300.101, and on May 1, 2026, Judge Daniella DeSeta Lyttle of the 261st District Court, Travis County, converted the TRO into an industry-wide temporary injunction. But the decisive development came in the parallel Sky Marketing Corp. v. DSHS case: on May 1, 2026, the Texas Supreme Court reversed the November 2021 injunction that had blocked DSHS’s Schedule I listing of non-delta-9 tetrahydrocannabinols (mandate issued June 5, 2026). DSHS republished the reinstated definitions in the Texas Register on July 10, 2026, effective July 31, 2026 — delta-8, delta-10, delta-6, and THCP are Schedule I, only delta-9-compliant hemp (≤0.3% delta-9) is exempt, and state guidance and press reporting confirm regulators consider THCA hemp flower among the prohibited products. The DSHS §300.101 rewrite was authorized by Governor Abbott’s Executive Order GA-56 (Sept 10, 2025). Underlying Texas statutes: Tex. Ag. Code §121.001 hemp definition (0.3% delta-9), Tex. H&S Code Ch. 443, HB 1325 (86R, 2019). SB 3 (89R, 2025) was vetoed by Gov. Abbott on June 22, 2025. The THBC challenge to the total-THC rule remains in the appellate process, but retailers should treat THCA flower as prohibited pending further court action — see the live Texas THCA page for the current posture.

Effective date: DSHS Schedule I listing effective July 31, 2026.

Federal Change Coming November 12, 2026

H.R. 5371, signed November 12, 2025, rewrites the federal hemp definition in Section 781. Two operative changes matter for THCA. First, the THC test moves from delta-9 only to total THC measured after decarboxylation — meaning labs calculate delta-9 plus 0.877 multiplied by THCA, and the result must be at or under 0.3% on a dry-weight basis. Second, any finished consumable hemp product is capped at 0.4 milligrams of total THC per container, where container means the innermost packaging that holds the product. Synthetically converted cannabinoids are excluded from the hemp definition.

For THCA flower, the practical effect on November 12, 2026 is binary. Flower that fails the post-decarboxylation total-THC test on that date stops being hemp under federal law and becomes Schedule I marijuana under the Controlled Substances Act, 21 U.S.C. § 812. FDA guidance is due within 90 days of enactment of H.R. 5371; the agency's draft guidance is expected before the November 12, 2026 effective date. Operators with existing inventory should plan for a hard cliff: there is no statutory grandfather clause in Section 781.

States retain independent regulatory authority. A state with no total-THC statute (South Carolina and North Carolina are the clearest examples among the five deep-dive states above) will see federal law become the binding constraint overnight. States already on a total-THC standard (Georgia) will see less change because state law has already done most of the work.

FAQ

Is THCA legal in the United States?

Federally, yes — for now. THCA hemp that tests at or under 0.3% delta-9 THC meets the 2018 Farm Bill definition of hemp. That changes November 12, 2026, when the federal definition moves to a post-decarboxylation total-THC test that most THCA flower cannot pass. State law varies from fully legal to felony, per the table above.

What states is THCA illegal in?

Arkansas, Idaho, Mississippi, and North Dakota prohibit THCA products outright; Alabama makes smokable THCA a felony (edibles are capped and licensed); and as of July 31, 2026 Texas treats THCA flower as a prohibited Schedule I product. Georgia bans THCA flower specifically while allowing compliant extracts and gummies. Tennessee banned THCA flower in its 2025 overhaul. Several more states restrict THCA into licensed cannabis channels.

Is THCA legal in Texas right now?

No — as of July 31, 2026, DSHS’s reinstated Schedule I listing of non-delta-9 THCs is in effect following the Texas Supreme Court’s Sky Marketing v. DSHS ruling, and Texas regulators treat THCA flower as prohibited. Litigation continues; check our live Texas THCA page before acting.

Is THCA the same as THC?

Chemically no — THCA is the non-intoxicating acid precursor of delta-9 THC. Heat converts THCA to THC (decarboxylation), which is why smoked THCA flower produces a marijuana-identical high, and why the new federal law counts THCA toward total THC at a 0.877 conversion factor.

Will THCA be legal after November 12, 2026?

High-THCA flower and pre-rolls will not qualify as federal hemp after that date — they become Schedule I marijuana under the total-THC test, with no grandfather clause for existing inventory. Delay and repeal bills are pending in Congress; absent passage, the cliff stands.

Can you fly or ship THCA flower?

Today, federally compliant THCA hemp can be mailed via USPS with documentation and flown domestically — but both carry elevated scrutiny, and both end when the federal definition changes. See our shipping guide and TSA guide.
