It's pretty basic, just like alcohol - in short, don't be stupid.

Tomorrow, December 6th, is the day that recreational marijuana officially becomes legal in the state of Michigan per last month's election. Commercial sales won't be regulated and likely begin until 2020, so you'll still need a medical card to purchase it until then.

But you CAN grow it yourself and give it to others who are over 21. Basically, here are the rules:

You CAN: 

  • smoke if you're over 21
  • grow your own weed
  • possess up to 10 oz
  • smoke in your own home

You CANNOT: 

  • smoke in public
  • sell the weed you grow yourself
  • smoke in your home if your landlord doesn't allow it
  • drive high/go to work high

So, again, it's basic "be a grown-up about this" rules. The state has to write a ton of regulations to sell it recreationally, so for now, this is the deal. Enjoy your ganja!
