Ohio's new adult-use rules cap what goes in a single package. The daily purchase limits haven't changed.

Ohio now limits how much cannabis can go into a single retail package, under a Division of Cannabis Control rule that took effect October 5, 2026, according to the authenticated Ohio Administrative Code (rule 1301:18-4-06). MMJ Daily reported the rules were brought into force on October 6. We haven't found the division's own announcement, so we can't say which date it uses; the rule text itself says "Effective: October 5, 2026."

Package limits are not purchase limits

A spokesperson for the Ohio Department of Commerce, which oversees the division, told MMJ Daily that the new numbers cap package size, not how much an adult can buy in a day. The spokesperson said daily transaction limits remain 2.5 ounces of flower and raw pre-rolls, and 15,000 mg of THC across other products, as set in the statute. We did not check those figures against the statute.

The caps, product by product

Under the rule, no product sold to customers may exceed 90 percent THC, and each package must contain between 90 and 110 percent of the total target THC concentration listed in the product's registration. The rule text below covers more product types than we list. For adult-use products, the main package caps are:

• Flower: up to one ounce per package.
• Plants: up to six clones, six live plants or six seeds per package. Clones and plants must still be in the vegetative stage.
• Vapes: up to three devices or cartridges per package, each with up to 2 grams of product and no more than 90 percent THC.
• Other concentrates: up to three containers, devices or cartridges, each up to 2 grams.
• Edibles: up to 10 mg THC per serving and 100 mg per package.
• Beverages: up to 10 mg THC per container, and no more than 12 containers per package.
• Oral pouches and strips: up to 10 mg per unit and 100 mg per package.
• Capsules and pills: up to 50 mg each and 1 gram per package.
• Patches: up to 50 mg each and 500 mg per package.
• Oral sprays and drops: packages up to 30 mL; sprays up to 1 gram THC per container; drops up to 10 mg per serving and 1 gram per package.
• Inhalers: one inhaler per package, up to 1 gram net weight and 800 mg THC.
• Topicals: up to 3 ounces (85 grams) and 1 gram THC per package.

The rule also defines serving sizes for labeling purposes. For vapes and other inhaled products, a serving is one two-second inhalation.

What's different for medical patients

Medical edibles and beverages keep a higher cap of 55 mg per serving, which the department said matches what patients could already get under the medical rules. A medical beverage container can hold up to 110 mg, and a package up to 220 mg.

Why Ohio changed the rules

According to the department, the adult-use program first borrowed limits from the medical program, which were never meant to be permanent. MMJ Daily reports that voters created the adult-use program by initiated statute in November 2023 and that Gov. Mike DeWine signed Senate Bill 56 in December 2025. The department said the new limits line up with both the initiated statute and SB 56.
