In Montana, passing someone a bowl of your medical marijuana could put you in prison for life.

There, an eight-woman, four-man jury found Matthew Otto, 27, guilty of a single charge of criminal distribution of dangerous drugs - in this case, 3 grams (well under an ounce) of marijuana. Otto faces a maximum penalty of life in prison and a $50,000 fine.
