It came as the state was still setting up its medical marijuana system, which voters approved by a wide margin two years ago.
The marijuana industry saw momentum in Tuesday's midterm elections.
MI voters legalized recreational marijuana use for residents over the age of 21 with retail sales of the product subject to a 10 percent tax. Businesses will be issued licenses and cannabis will be subjected to a 10 percent excise tax in addition to a 6 percent state sales tax.

A Gallup poll released last month found that 66 percent of Americans, the highest level ever in the firm's almost 50 years of surveys on the topic, support marijuana legalization. Amendment 3 would allow doctors to prescribe weed, but would impose a 15-percent tax and ban home cultivation; and Proposition 3 would tax marijuana at 2 percent and set a list of qualifying conditions. They clearly were not ready to take the next step, although two-fifths of them said yes to a sweeping ballot initiative that aimed to legalize all peaceful marijuana-related activities (except for sales to minors) and create a system of automatic expungement for people convicted of such offenses.
"Encouragingly, support for cannabis achieved bipartisan support a year ago and Republican support was up 2 percentage points in 2018 to 53 percent", Azer told CNBC last week.
