The first medical marijuana licenses are being issued to businesses in Michigan this summer.

The new regulations are emerging from the cloud of legal confusion that had been lingering over the industry for the past decade in the state, after voters legalized medical marijuana in 2008.

State officials are now telling currently operating businesses from medical marijuana growers to processors, transporters, testers and provisioning centers that they must be licensed by Sept. 15 -- or be forced to shut down.

There are at least 230 businesses operating now, state officials said; and a total of 637 businesses have applied for licenses.

As of Aug. 9, 16 licenses have been approved for medical marijuana businesses by the state board: Seven provisioning centers, two processors, two safety compliance facilities, four grower licenses to one business and one secure transporter.
