What Ohio law says about THCA

Ohio voters legalised adult-use cannabis through Issue 2 in November 2023, creating a licensed dispensary system overseen by the Division of Cannabis Control. Senate Bill 56, in force from 20 March 2026, then closed the hemp route for THCA.¹²

The amended section 928.01 defines hemp as cannabis with a total tetrahydrocannabinols concentration, including tetrahydrocannabinolic acid, of not more than 0.3% on a dry weight basis. Finished hemp-derived cannabinoid products are also limited to 0.4 mg of total THC per container.¹ THCA flower sold as hemp in smoke shops almost always exceeds both limits, so it is now marijuana under state law.

Adults 21 and over can still buy THCA-rich flower legally from Ohio-licensed dispensaries, where SB 56 caps plant material at 35% THC and products must be grown, processed and tested within the state.²³ SB 56 also requires marijuana to stay in its original packaging and makes it unlawful to bring cannabis bought in other states into Ohio.²⁴ Hemp businesses argue that enforcement favours dispensaries, but the Department of Commerce says Issue 2 never covered intoxicating hemp.⁵

Pending changes to watch

Litigation continues: a July 2026 federal court injunction protects only the beverage businesses that sued, and a Sandusky County judge issued a temporary block in March 2026 whose scope was not confirmed. A veto override on the beverage grace period would need a vote before the session ends in December 2026.

How the federal hemp change affects Ohio

Separate from Ohio law, the federal definition of hemp is changing. Under the federal hemp redefinition passed in the FY2026 appropriations law, from 11 December 2026 hemp is measured by total THC, which counts THCA as well as delta-9 THC, and finished products are capped at 0.4 mg of total THC per container. High-THCA flower sold as hemp today will not meet that definition, so from that date it is treated as marijuana under federal law, whatever state law says.

Bills to delay or repeal the change are in congressional committees, but none had advanced as of September 2026. Our explainer on the federal hemp THC limit covers the detail, and THCA vs delta-9 THC explains why heat turns THCA into delta-9.

Timeline of recent changes

• 20 March 2026: SB 56 took effect, defining hemp by total THC including THCA and limiting THCA flower sales to licensed dispensaries.
• 19 December 2025: Governor DeWine signed SB 56 into law.
• November 2023: Voters approved Issue 2, legalising adult-use cannabis for adults 21 and over.

THCA in neighbouring states

Rules change at the state line. Here is how THCA is treated in the states bordering Ohio, as of September 2026:

• Michigan: Licensed marijuana stores only, 21+
• Indiana: Banned (smokable hemp law)
• Kentucky: Flower and high-THCA sales banned
• West Virginia: Banned above 0.3% total THC
• Pennsylvania: Grey area, no state rules

Carrying products across state lines can break the law of the state you enter, and federal law also applies. Check the destination state’s rules first.

Delta-8 in Ohio

Delta-8 is treated differently: in Ohio it is Banned as hemp since March 2026 as of September 2026. Read our guide to Delta-8 law in Ohio, or compare the two compounds in THCA vs Delta-8.

Frequently asked questions

Is THCA flower legal in Ohio?

Only from a licensed dispensary. Since 20 March 2026, Ohio has counted THCA towards the 0.3% total THC limit for hemp, so THCA flower is marijuana under state law. Adults 21 and over can buy it from dispensaries licensed by the Division of Cannabis Control.

Can smoke shops in Ohio still sell THCA?

No. Senate Bill 56 ended the sale of THCA flower and other intoxicating hemp products outside licensed dispensaries. Selling these products without a licence is now treated as selling marijuana, which carries criminal penalties under Ohio law.

Did the referendum stop Ohio’s hemp law?

No. Ohioans for Cannabis Choice tried to put SB 56 to a referendum, but the campaign did not gather enough valid signatures before the March 2026 deadline. The law took effect on 20 March 2026, and legal challenges have not blocked it statewide.
