Is THCA Legal in Arkansas? — 2026 Guide

Hemp-derived THCA flower and most intoxicating-cannabinoid products are not legal to sell or ship in Arkansas: Act 629 (2023) closes the federal Farm Bill loophole at the state level by banning THCA along with delta-8, delta-10, and synthetically converted cannabinoids — and a federal court declined to enjoin the law in October 2025.

The short answer

Arkansas is one of the most restrictive THCA jurisdictions in the country. Act 629 (2023) — originating as HB 1640 — explicitly classifies THCA, delta-8, delta-10, and other intoxicating hemp-derived cannabinoids as controlled substances under Arkansas law, regardless of whether they meet the federal Farm Bill’s 0.3%-delta-9-at-harvest threshold. The state’s medical cannabis program (Amendment 98) is unaffected, but recreational hemp-derived THCA is functionally banned. A federal court declined to enjoin Act 629 in October 2025; an industry appeal is pending. Possession and sale carry criminal penalties under Arkansas’s controlled-substances scheme.

What “Arkansas Act 629 (2023)” actually says

Act 629 amends Arkansas’s Uniform Controlled Substances Act to add intoxicating cannabinoids — including THCA, delta-8-THC, delta-10-THC, HHC, THC-O, and other synthesized or converted hemp-derived cannabinoids — to Schedule VI alongside marijuana. The law also requires total-THC testing for hemp products and prohibits products manufactured using “synthetic” or “converted” processes, even when starting from federally compliant hemp.

In plain English: Arkansas drew a sharp line. The state’s view is that the 2018 Farm Bill’s “0.3% delta-9” threshold was never intended to legalize intoxicating products, and Act 629 forecloses the loophole at the state level. Whether a flower bud’s COA shows compliant delta-9 at harvest is irrelevant under Arkansas law if the product is intoxicating in use.

This is the same regulatory pattern as Idaho — outright prohibition rather than the total-THC frictions used in California or Georgia. Read the bill text on the Arkansas Legislature site.

Federal preemption: why Act 629 still stands

Industry plaintiffs — including national hemp brands — challenged Act 629 on federal preemption grounds, arguing that the 2018 Farm Bill’s protection of interstate hemp commerce overrides Arkansas’s authority to ban federally compliant hemp.

In October 2025, a federal court declined to enjoin the law, reasoning that states retain regulatory authority over intrastate sale and possession even of federally compliant hemp. An appeal is pending in the Eighth Circuit. Until the appeal resolves, Act 629 is enforceable, and Arkansas authorities have publicly reaffirmed enforcement against unlicensed THCA flower sales.

For consumers, the practical takeaway: federal Farm Bill preemption protects interstate transit, but the moment a package reaches an Arkansas address, it is governed by Arkansas controlled-substances law.

Can you legally buy THCA online in Arkansas?

No. Reputable national THCA brands geofence Arkansas — meaning Arkansas addresses cannot complete checkout. We do not list Arkansas-shipping options because we cannot direct readers toward conduct that risks state criminal liability.

CBD products with 0.3% or less delta-9 THC and no detectable THCA are generally legal in Arkansas under separate hemp-product rules. Adults seeking medical cannabis can apply through the Arkansas Medical Marijuana Program under Amendment 98.

What’s the penalty for THCA in Arkansas?

Under Arkansas’s Schedule VI classification, possession penalties for THCA flower or other intoxicating hemp-derived products generally track the state’s marijuana penalties:

• Less than 4 ounces — typically a Class A misdemeanor on first offense, with possible jail time and fines.
• 4 ounces or more — felony classifications with materially more serious penalties.
• Sale or distribution — felony with sentencing depending on quantity and circumstances.

These penalties are not theoretical. Arkansas authorities have publicly reaffirmed enforcement against unlicensed THCA flower sales, and the state Attorney General has issued advisories to clarify the prohibition.

Recent legal developments

• 2026-02-20 — Arkansas authorities reaffirmed their enforcement stance against unlicensed THCA flower sales.
• 2025-10-10 — A federal court declined to enjoin the Arkansas hemp ban; the industry appeal is pending in the Eighth Circuit.
• 2025-06-04 — The Arkansas Attorney General issued an advisory on hemp-derived cannabinoids, formalizing the prohibition position.

How Arkansas compares to neighbors

Arkansas is sharply more restrictive than Texas, Louisiana, Mississippi, Tennessee, and Missouri. Texas, Louisiana, and Mississippi all allow Farm Bill-compliant THCA in some form (each with their own retail rules); Tennessee operates a regulated hemp-cannabinoid market; Missouri has an active adult-use cannabis market. The Mid-South map looks like a quilt of permissive states surrounding a restrictive island, which is why Arkansas consumers seeking THCA frequently cross state lines — though importing the product back into Arkansas remains a state-law violation. Idaho is the only nearby parallel for outright prohibition.

What could change in 2026-2027

Two scenarios are plausible. First, the Eighth Circuit appeal could narrow Act 629’s scope through a federal preemption ruling — though this is unlikely given current federal court trends. Second, the federal Farm Bill rewrite, currently pending in Congress, could either codify a federal total-THC standard (which would harmonize federal law with Arkansas’s view) or reaffirm the existing harvest-time delta-9 definition (which would strengthen the preemption argument). Until either resolves, Act 629 stays enforceable as written.
