In the four states that were among the first to legalize pot – Colorado, Nevada, Oregon and Washington – crashes were up by as much as 6% compared with neighboring states without legalized recreational weed, according to analysis of collision loss data from January 2012 through October 2017 by the Insurance Institute for Highway Safety and an October 2018 report done by the Highway Loss Data Institute.
