While two of three states with marijuana initiatives were passing them, a much quieter approach was taken in Ypsilanti, Michigan. The measure, which passed with 74% of the vote, reads:
Shall the Ypsilanti City Charter be amended such that the use and/or consumption of one ounce or less of usable marijuana by adults 21 years or older is the lowest priority of law enforcement personnel?
This doesn’t change the law, it just directs the use of public resources. You should consider trying it in your city.
