A bill amending Michigan's medical marijuana law to specify where medical marijuana cannot be smoked has passed the state Senate.
The bill was approved 31-7 Tuesday and prohibits smoking or growing medical marijuana on private property if the property owner won't allow it. The amendment also bans smoking on private property that is open to the public.
Michigan's 2008 voter-approved law allows the possession, cultivation and use of limited amounts of marijuana for people suffering from debilitating conditions. It originally banned the use of medical marijuana in any public place, including on public transportation.
The bill now moves to the House.
