Bulletin No. 1 | An Act Modernizing the Commonwealth’s Cannabis Laws | April 17, 2026

This bulletin applies to all Marijuana Establishments and Medical Marijuana Treatment Centers (collectively referred to as “Licensees”). The Cannabis Control Commission (“Commission”) is hereby notifying Licensees that the Massachusetts House and Senate have enacted H.5350, An Act Modernizing the Commonwealth’s Cannabis Laws, which is on Gov. Maura Healey’s desk for consideration to become law no later than April 19, 2026. A summary of the legislation is available through the Legislature.

This new statute offers notable changes to our regulated cannabis industry and the Commission. If signed by the Governor, it would immediately increase the total amount of Marijuana flower that an individual who is 21 years of age or older may possess, from 1 ounce to 2 ounces, or its equivalent in Marijuana concentrate, as the result of a licensed sale or gifting. Note: Commissioners voted April 16 to issue an administrative order if the law takes effect with the possession limit increase that will direct Marijuana Establishments to implement the change.

The legislative reforms further task the Commission with promulgating new regulations to establish conversion standards for Marijuana concentrates, infused products, and other formats to ensure equivalency based on potency and product form.

Two-ounce Flower Limit

The Commission has confirmed with Metrc that the seed-to-sale tracking system already has the technological capacity to support sales transactions of up to 2 ounces. Licensees are advised to communicate this change as soon as possible with their chosen point-of-sales providers and/or Third-party Technology Platforms to ensure they can enable larger sales, especially if they want the update in place ahead of April 20, one of the busiest retail and delivery days of the year.

Equivalency

Prior to the promulgation of new regulations, adult-use Licensees should continue to rely upon 935 CMR 500.000 to extrapolate Marijuana concentrate limits (see 935 CMR 500.140(3)). Currently, the weight of Marijuana flower is not translated to an equivalent weight of Marijuana concentrate, but to the weight of the THC in that concentrate. Pursuant to 935 CMR 500.140(3), one ounce of Marijuana flower is equivalent to: (i) five grams of active THC in Marijuana concentrate; and (ii) 500 mg of active THC in edibles. Once signed by the Governor, if H.5350 language remains as passed by the Legislature, the new adult-use purchase limit of two ounces of Marijuana flower should be understood to be equivalent to: (i) 10 grams of active THC in Marijuana concentrate; and (ii) 1,000 mg of active THC in edibles.

For Licensees that operate as part of the Medical Use of Marijuana Program, 935 CMR 501.000 does not account for the THC content of Marijuana concentrate or edibles. Medical Licensees should continue to respond to patient allotment in terms of Marijuana flower weight. Guidance and/or protocol must be used to establish standards for how that is converted into an “equivalent” weight of Marijuana concentrate.

Under these latest legislative reforms, Patients and Caregivers may continue to purchase up to 10 ounces of Marijuana flower, or up to 1.9 ounces of Marijuana concentrate, regardless of its THC content (see Usable Marijuana Content, pages 16-17 of Protocol for the Sampling and Analysis of Finished Marijuana Products and Marijuana Products for Marijuana Establishments, Medical Marijuana Treatment Centers, and Colocated Marijuana Operations).

Next Steps

Many of the new provisions will take effect immediately upon receipt of the Governor’s signature, subject to the Commonwealth’s process for promulgating regulatory amendments or other forward-looking deadlines set by law. Learn more about what it takes for a proposed revision to become a new regulation through the Commission’s explainer video, From Idea to Regulation: An Overview of the Massachusetts Cannabis Regulatory Process.
