Michigan’s emergency rules governing medical marijuana got tweaked again Monday, with the state imposing a Halloween deadline for dispensaries to either get a state license or be forced to shut down.

That’s six weeks before the Dec. 15 deadline that regulators designated two weeks ago after a Court of Claims judge overruled the state’s plan to treat two different classes of dispensaries differently.

The moving target for licensure or closure has been a roller coaster for the 206 dispensaries that have been operating with approval from their local communities, but still haven’t gotten a state license.

The first deadline was June 15 for dispensaries to get a license or shut down. But the state didn’t approve the first dispensary license until July 12, so the June deadline was extended to Sept. 15.

The state was firm that the Sept. 15 deadline was the cutoff for all of the dispensaries to shut down until Judge Stephen Borrello overruled a plan to make 98 dispensaries that hadn’t turned in completed applications to close on Sept. 15, but allow 106 retail shops that had turned in all steps of their application, which included building plans as well as community approval, to stay open until Dec. 15.
