Michigan: CRA Revokes 20 Marijuana Grower Licenses For Company’s Egregious Conduct

Oct 2, 2026 | Feature, Great Lakes Region, Michigan

The Cannabis Regulatory Agency revoked 20 Class C grower licenses that had been held by a limited liability company doing business in Michigan. An investigation by the CRA found GP Holdings transferred packages to a licensed processor under manifests that identified the contents as marijuana flower. 

The material that was tested resembled dirt and mulch, according to a release from the department. More tests of other packages that were being distributed “appeared to be shake, kief, or post-harvest plant waste” despite being identified as marijuana flower.

There were other violations that were uncovered, which led to a $2 million fine.
