October 5, 2026
As of October 5, no cannabis product sold at an Ohio dispensary can test above 90% THC, and no package can hold more than an ounce of flower, three vapes, or 100 milligrams of adult-use edibles. Those limits are in Ohio Administrative Code 1301:18-4-06, which takes effect October 5, 2026. It is the last of six new packaging and labeling rules from the Division of Cannabis Control. The other five took effect September 11.
The six rules cover the THC symbol, packaging approval, label contents, banned content, single-serving units, and per-package limits. "The new rules apply to both medical and non-medical cannabis," the division wrote in its business impact analysis. Together they make up Ohio's dispensary packaging rules for 2026, replacing rules written for the medical-only program. If you make packaging, labels, or hardware for Ohio products, these rules are now your specifications.
Rule 4-06 sets a ceiling for each product format. Every package also has to test within 90% to 110% of its registered THC target.
| Product | Limit per package |
|---|---|
| Flower | 1 ounce |
| Vapes | 3 devices or cartridges, 2 g each, 90% THC max |
| Concentrates | 3 containers, 2 g each |
| Adult-use edibles | 10 mg per serving, 100 mg per package |
| Medical edibles | 55 mg per serving, 10 servings |
| Adult-use beverages | 10 mg per container, 12 containers |
| Oral pouches and strips | 10 mg per unit, 100 mg per package |
| Capsules | 50 mg each, 1 g per package |
| Infused single-serving units | 500 mg each, 1,500 mg per package |
| Topicals | 3 oz (85 g), 1 g THC |

Some products have been packaged to these limits for months. A March 2026 Metrc bulletin let licensees start packaging under the proposed limits, including flower "in any increment up to one ounce." The division also notes that licensees were already required to submit packaging for approval, at no fee. We could not confirm from the public record which limits are new and which carry over from the medical rules, so vendors should check each product line against the rule text.
Rule 1301:18-4-04 requires the universal THC symbol, at least a quarter inch square, on every serving or unit, on retail packages, on bulk transfer packages, and in ads. It must be permanently affixed in a contrasting color or molded in so it can't be removed.
The rule also covers devices. The symbol has to appear on "any portable, hand-held cannabis device used to administer cannabis that would cause a reasonable person to believe the device does not contain cannabis." The division acknowledged the cost: "Placing the THC symbol on devices, such as vapes, may add additional expense due to customization of the devices ordered." For edibles, it said the symbol is usually handled with molds that already include it.
Under 1301:18-4-19, every cultivator and processor must petition the division for written approval before using any retail packaging. The petition has to show the package is tamper-evident and child-resistant under the federal standard in 16 CFR 1700. It also needs renderings of the full package, the THC symbol, and the DCC seal. Nothing in the package can be sold until the division approves it in writing.
Rule 4-20 puts net weight or volume, product name, THC symbol, and DCC seal on the front of every package. Edibles must say "cannabis-infused" or "marijuana-infused." Required warnings include "Caution: When eaten or swallowed, effects and impairment may be delayed" for edibles and "Smoking and vaporization is hazardous to your health" for smokable and vape products. Products with hemp-derived ingredients have to say so. Expiration dates can't be more than a year from manufacture, and QR codes can carry some required information.
Rule 4-21 lists what packaging can't do. It can't be "attractive to children" or reference "a cartoon character, fictional character or pop culture icon whose target audience is children or youth." It also bans depictions of consumption, health claims, and anything implying state endorsement. California is moving the same way: AB 2249, signed August 31, sets its own child-appeal standard with a January 1, 2028 deadline.
Rule 4-23 caps single-serving unit lots at 10,000 units. Test samples must be at least 30 grams for lots under 13 pounds; for larger lots, the sample is 0.5% of net weight or 30 grams, whichever is more. Infused units must list total milligrams of cannabinoids and terpenes per package and disclose any solvent extraction.
Vape hardware suppliers have the most concrete change. A device that doesn't look like a cannabis product needs a permanent THC symbol, and the 2-gram, 90% THC, three-per-package ceilings decide which SKUs an Ohio brand can order.
Packaging and label vendors are now working to a published spec: child-resistant certification, approval renderings, and a fixed list of front-panel fields and warning text. A design that fails 4-21 means a rejected petition, and the product can't ship until a new one is approved.
Edible and beverage brands are capped at 100 mg per package and 12 cans. Multi-pack formats from other states may not fit.
Dispensary buyers will drop products that don't meet the limits. Multi-state brands will need Ohio-specific SKUs, and their sales teams will be pitching those SKUs to Ohio stores while also selling the standard versions to dispensaries in other states.
This is a summary of the rule text, not legal advice. Licensees and their vendors should confirm specific products with the Division of Cannabis Control or counsel.
