Minnesota became the 22nd state to legalize medical marijuana use and, as part of the new law, to enact new potential employment protections for registered users of medical marijuana. Minnesota’s new marijuana law has already gone into effect, but distribution of marijuana for medical purposes is not expected until July 1, 2015. Employers should use this extra time to familiarize themselves with the new law and its potential implications. It is currently unclear if courts will strictly enforce the new state law against employers or whether the federal law criminalizing all marijuana use will trump the new state law.
