Missouri Bets On Marijuana Research As It Opens Unlimited Licensing Pathway

Missouri is moving to allow unlimited marijuana research licenses.

Under the filed proposed rules with the Secretary of State, the state marijuana regulator outlined what research license holders can do and how to apply.

Rieka Yu, policy director for the Missouri Division of Cannabis Regulation, praised the push to advance cannabis research.

“Ultimately, it’s just exciting to make progress on marijuana research because we know that that’s been historically difficult,” Yu said.

The proposed rules, which will be made public on May 1 via the Missouri Register’s issue on the Secretary of State’s website, stem from the 2022 policy change when voters in the Show-Me State passed Amendment 3 with 53.1% of the vote, effectively legalizing recreational cannabis.

The constitutional amendment allowed the state to create licenses aimed at supporting scientific research and educational initiatives. However, Missouri is required to finalize administrative rules before the program can be kicked off, reported the Missouri Independent.

The division launched the process in August, releasing draft rules for informal public comment.

Beginning in May, the division will introduce a second comment period that will last until May 31. It is aimed at refining the rules ahead of submitting a final version for formal rulemaking this summer.

The rules then need to go through approximately eight months of legislative review prior to final publication.

Amy Moore, the division’s director, said that the division, as a public health agency operating under the Missouri Department of Health and Senior Services, is “interested in health research, but it’s not limited to that.” However, she emphasized that establishing a regulatory framework is not enough to attract interest in the license, referring to funding challenges.

Why It Matters

The regulatory change has the potential to place Missouri on a map of hubs for ag-tech innovation. Having in mind that cannabis research is closely tied to highly controlled indoor environments, companies operating within controlled-environment agriculture (CEA) supply chain segments could benefit.

That said, an open research environment could attract scientists, specialists in the fields of Ag-tech and biotech, and University partnerships.

Nevertheless, with $1.5 billion in total sales in 2025, nearly 400 licenses, and over 190 dispensaries, Missouri offers an established, expanding market with predictable revenue streams.

March cannabis sales totaled $133.3 million. That’s a 1.9% increase in sales year-over-year, as per the latest Headset data. These figures put the state cannabis market in line with Massachusetts and higher than Arizona and Nevada.

The Show-Me State is already operating at scale, among mid-tier U.S. markets by size. At the retail level, Missouri generates approximately $6.7 million in annual revenue per store, with ~46% retail gross margins, highlighting relatively strong unit economics compared to more saturated markets.
