As of December 6, 2018, 32 states plus the District of Colombia and Puerto Rico, have legalized medical marijuana. Ten states, including Michigan, have legalized marijuana for recreational purposes, too.
People who are not U.S. citizens may believe that using marijuana in Michigan—whether for recreational or medical use—is permissible and will not affect their immigration status. Unfortunately, that is wrong!! It is still a federal offense to possess marijuana even if, under state law, it is legal for medical or recreational purposes.
