I didn't even know what the law says. I had to look it up.
"In Michigan, only adults over the age of 21 may use cannabis legally.
Michigan law requires that anyone using cannabis must do so in private, such as in their own residence. It is illegal to use cannabis in a public place, such as on the street or at the park.
You may possess up to 10 ounces of cannabis in your residence, you may not carry more than 2.5 ounces of cannabis on your person when out in public.
In Michigan, adults may grow up to 12 marijuana plants at their own residence for their personal use. However, adults may not grow marijuana plants that are visible from a public place."
So basically it's a free-for-all.
What area do you live in? I have some genealogy friends who live in Niles and I have some 2nd cousins who live in the Kalamazoo/Cold Water area.
