In Michigan, the law stops short of fully legalizing the use of medical marijuana. This can make the whole legal scenario difficult to grasp. It is important that you know the law and know your rights when using medical marijuana in Michigan. You don’t want to make costly mistakes, and you definitely do want to be able to stand your ground and know your rights if you ever need to defend them for any reason.
