Is HHC Legal in Arkansas?

Last reviewed: May 20, 2026

No. HHC is named in Act 629 of 2023 as a Schedule VI controlled substance under the Arkansas Controlled Substances Act. The Eighth Circuit reversed the federal preliminary injunction that had blocked Act 629 in Bio Gen LLC v. Sanders, No. 23-3237 (June 24, 2025). Act 934 of 2025 reinforced the framework on a total-THC basis. Attorney General Tim Griffin certified Act 934 on April 22, 2026, and the Department of Finance and Administration began field seizures within weeks.

Arkansas Cannabis and Hemp Overview

Arkansas voters approved medical cannabis through Issue 6 in 2016. The state has not legalized adult-use cannabis. The Arkansas Department of Agriculture administers the licensed hemp cultivation program under federal Farm Bill standards. The criminal-law overlay sits in the Arkansas Controlled Substances Act, which Act 629 amended in 2023 and Act 934 further expanded in 2025.

HHC is hexahydrocannabinol, a hydrogenated form of THC produced almost exclusively through chemical conversion from hemp-derived CBD or delta-9. That synthetic-conversion production method is what state regulators target when they restrict intoxicating hemp cannabinoids. For comparison see our Arkansas delta-8 page.

What Arkansas Law Actually Says

Act 629 amended the Arkansas Controlled Substances Act to add delta-8 THC, delta-10 THC, HHC, THCO, and several other named intoxicating hemp cannabinoids as Schedule VI substances. HHC was one of the specifically named compounds in the 2023 statute, so it has been clearly inside the prohibited category since the Eighth Circuit mandate issued in 2025. Act 934 of 2025 added a total-THC reading that closes off product configurations the named-isomer approach did not capture.

The state-licensed medical cannabis program is administered separately and was not affected by either statute.

How Enforcement Has Played Out

The Department of Finance and Administration began joint inspections of smoke shops, convenience stores, and gas stations the week the Eighth Circuit mandate issued. HHC vapes and gummies, distributed heavily through convenience-store and vape-shop channels, were among the product categories targeted in early stop-sale orders. DFA reported more than 6,000 hemp product seizures and 2,800-plus in-person retail visits in the first wave. The April 2026 Griffin certification press conference signaled continued enforcement priority for hydrogenated and synthetic-conversion cannabinoids.

What This Means for Retailers Selling HHC in Arkansas

• Stop selling HHC vapes, gummies, tinctures, and concentrates. HHC is specifically named in Act 629 and the Eighth Circuit reversed the injunction that had blocked enforcement.
• Pull obvious enforcement-bait packaging that mimics candy brands or marijuana branding. This has been the consistent first DFA target.
• Keep certificates of analysis on file for any non-intoxicating CBD or CBG inventory you continue to carry. State inspectors increasingly request finished-product testing rather than relying on cultivator paperwork.
• Plan now for federal H.R. 5371 §781 taking effect November 12, 2026. HHC sits squarely inside the excluded synthetic-cannabinoid category in the new federal definition and loses Farm Bill protection on that date.
• Bio Gen has been remanded to the Eastern District of Arkansas for further proceedings. The structural ban is in force but additional cannabinoid-specific rulings are possible.
• Verify ID at point of sale for any remaining hemp products. The 21-and-up industry standard applies even where statutory age minimums are silent.

What This Means for Consumers Buying HHC in Arkansas

You cannot buy HHC products at Arkansas retail. Some out-of-state online retailers will ship to Arkansas addresses, but the products are illegal under Act 629 and subject to DFA seizure on delivery. HHC metabolites overlap with delta-9 THC metabolites on most standard drug tests and will typically trigger a positive result.

Pending Federal Change

H.R. 5371 §781, signed November 12, 2025, explicitly excludes synthetic and chemically converted cannabinoids from the federal hemp definition. HHC is produced almost exclusively through hydrogenation of hemp-derived CBD or delta-9, which places it squarely inside the excluded category. The provision takes effect November 12, 2026 and removes federal Farm Bill cover for HHC nationwide. For broader background see our 2018 Farm Bill revision explainer.

What is HHC?
Hexahydrocannabinol, a hydrogenated form of THC produced through chemical conversion from hemp-derived CBD or delta-9. HHC is structurally similar to delta-9 THC but the molecule is fully saturated, which affects shelf stability and pharmacological profile.

Does HHC show up on a drug test?
HHC metabolites overlap with delta-9 THC metabolites on most standard urine, saliva, and hair screens and will typically trigger a positive. Some specialty panels may distinguish them but those panels are uncommon.

Can I order HHC online to Arkansas?
Out-of-state retailers will sometimes ship, but the products are illegal under Act 629 and subject to DFA seizure on delivery.

How does HHC compare to delta-8 in Arkansas?
