Forty medical marijuana businesses across the state will not be opening on Friday.
The Detroit News is reporting state officials and state police gave the businesses cease and desist orders on Thursday.
The state department of licensing and regulatory affairs is shutting down medical marijuana businesses operating illegally because they haven't submitted applications to the state for a license.
The deadline to do that was February 15th.
Any shop that didn't meet the deadline and continues to operate without sending in an application will potentially lose out on getting a license.
The department says this is just the beginning, as hundreds more are expected to get cease and desist letters in the coming days.
