Maine Edibles Laws: THC Limits, Packaging & Testing Rules
A concise guide to current statute, final rules, 2026 testing guidance, and proposals
Current law versus proposed rules
Potency and product form
28-B M.R.S. §703 caps adult-use edibles at 10 milligrams of THC per serving and 200 milligrams per package, subject to the statute’s variance provisions. The product must be homogeneous, and it may not be manufactured in the distinct shape of a human, animal, or fruit.
The same section bars adulterated or misbranded edibles and limits use of trademarked food or drink products. These are statutory requirements, separate from additional details in OCP’s rules.
Labels, packaging, and the universal symbol
28-B M.R.S. §701 requires applicable license numbers, identity statement and universal symbol, health and safety warnings, batch number, net weight, cannabinoid potency, servings per package, ingredients and possible allergens, a recommended-use or expiration date, and a nutrition facts panel for edibles.
Adult-use cannabis products must be prepackaged in child-resistant and tamper-evident packaging or placed in compliant packaging at the final point of sale. A multi-serving liquid product also needs an integral one-serving measurement component and a child-resistant closure.
Under §703, each serving must carry the universal symbol by stamping, embossing, individual wrapping, or blister packaging unless OCP determines that treatment impracticable. The statute names gummies and certain loose snack products as examples; when impracticable, the symbol must be affixed to the package.
OCP’s current final Chapter 30 rule, effective November 6, 2024, supplies further label and packaging detail. It prohibits retail labels from making health or physical-benefit claims.
Testing: the 2026 statutory change
OCP's April 28, 2026 implementation guidance explains that P.L. 2025, ch. 764 effective April 19, 2026 amended § 602(1)(F) and was effective immediately. When every cannabis concentrate input used in the edible has passed all required mandatory contaminant testing, the finished edible is not subject to another round of mandatory contaminant testing. The exception remains subject to § 605's prior-testing, documentation, and tracking conditions. The finished edible still must undergo testing for THC potency, cannabinoid profile, and homogeneity before retail sale.
The current final Chapter 40 rule, effective November 6, 2024, remains part of the governing testing framework except where later controlling law applies. OCP's draft Chapter 40 would incorporate the statutory edible testing exception, but businesses should not treat draft language as an adopted requirement.
Who may manufacture for the adult-use market
Commercial adult-use cannabis products must move through Maine’s licensed Adult Use Cannabis Program. OCP’s rules and statutes hub links the current Title 28-B statute and Chapters 5, 10, 20, 30, and 40. A products manufacturing facility must hold the appropriate OCP license and follow its approved plans and the requirements applicable to its actual process and product.
This page does not infer separate food-service credentials, kitchen specifications, inspection schedules, or manufacturing fees beyond what the current official authority states for the particular license and facility.
Cautious consumer safety
Maine CDC says edibles take longer to produce effects than inhaled cannabis and can make accidental overconsumption easier. Do not drive while impaired. Store products in their original packaging in a locked box or pouch, away from children, pets, food, and medications.
A systematic review of human oral-THC pharmacokinetics found high variability in absorption and delayed peak plasma concentrations compared with other routes. It supports caution about timing but does not provide an individualized dose.
If a child may have consumed cannabis, call Poison Control at 1-800-222-1222. For a severe reaction, call 911 or go to an emergency room. Do not rely on food, water, CBD, or another home remedy to reverse a reaction. The FDA warns that unapproved CBD products have unproven claims and may carry drug-interaction, liver-injury, and sedation risks.
A Pediatrics poison-center analysis documented 7,043 edible-cannabis exposures in children younger than six from 2017 through 2021, most in residences. This supports locked household storage and prompt poison-center consultation after a suspected exposure.
Frequently asked questions
How much THC may a Maine adult-use edible contain?
Under 28-B M.R.S. §703, an adult-use edible may not contain more than 10 milligrams of THC per serving or 200 milligrams per package, subject to the statute’s specified variance provisions.
What packaging is required for Maine adult-use edibles?
Adult-use cannabis products must be in child-resistant and tamper-evident packaging before sale or placed in compliant packaging at the final point of sale. The statute also requires the universal symbol on each serving by stamping, embossing, individual wrapping, or blister packaging unless that treatment is impracticable; in that case the symbol must be on the package.
What testing is required for adult-use edibles in Maine in 2026?
OCP’s April 28, 2026 guidance says an edible made with cannabis concentrate that already passed all required contaminant testing does not need finished-product contaminant testing, but the edible must still be tested for THC potency, cannabinoid profile, and homogeneity. The current final Chapter 40 rule remains part of the governing framework; OCP’s July 2026 Chapter 5 and Chapter 40 drafts are proposals, not effective rules.
What should I do if a child accidentally eats a cannabis edible?
Maine CDC says to call Poison Control at 1-800-222-1222. If the reaction is severe, call 911 or go to an emergency room. Keep cannabis in its original packaging, locked away from children, pets, food, and medications.
