Michigan government officials face a ticking clock to launch a commercial marijuana industry in the state after voters approved Proposal 1 Tuesday.

"We have a year to do this," said Shelly Edgerton, director of the Department Licensing and Regulatory Affairs (LARA), which will oversee the implementation of Proposal 1.

The law will take effect likely by mid-December, once election results are certified and 10 days have passed. The state then has one year to develop rules, regulations and to issue the first business licenses to recreational marijuana companies.

All of the marijuana and marijuana products sold at future retail shops in Michigan must be grown, processed and tested in Michigan.

Edgerton said the department is taking a "deep dive" into the language of the proposal. LARA oversees a number of regulatory functions, including liquor licenses, medical marijuana caregivers and patients as well as the licenses for medical marijuana businesses.

Unlike medical marijuana licenses -- which are the most difficult license to obtain from LARA due to extreme scrutiny and approval from an appointed board -- Edgerton said recreational marijuana business licenses would likely be easier to obtain. The department would be in charge of all license approvals.

"I would hope we could create greater efficiencies in the adult use license," Edgerton said. "Some of the language is not as stringent as it is on the medical side."

Licensing medical marijuana businesses has been rocky, as attempts by state regulators to impose deadlines for compliance have been successfully challenged twice in court.

The first order of business for LARA is to write the rules and regulations. Edgerton said the state would be gathering stakeholders including attorneys, patients and caregivers to help guide the process.

Medical marijuana businesses with state licenses will be given the first opportunities to obtain recreational licenses. Proposal 1 limits who can obtain a license at first.
