Traverse City Record-Eagle, 30 May 2013 – TRAVERSE CITY — Local authorities dropped criminal charges against a Williamsburg man whose 2010 arrest spurred statewide changes for medical marijuana patients who drive with the drug in their system. Grand Traverse County Prosecutor Bob Cooney on Thursday formally dismissed operating while intoxicated charges against Rodney Koon, 51, following a Michigan Supreme Court decision this month. The court’s ruling effectively dismantled a state law that dictated a "zero tolerance" approach to medical marijuana users like Koon.
