The Minnesota House passed a medical-marijuana proposal on Friday. Like the Senate’s, the House’s bill offers patients marijuana in pill, oil or vapor form and prohibits smoking the drug. The House bill establishes three medical marijuana dispensaries. The Senate version sets up 55. Governor Dayton has sent a letter to House and Senate sponsors saying that he would sign the bill into law if legislators adopted the House version as is. Dayton said components that made the House measure superior included an observational study, consumer assistance and fewer dispensaries. The Senate options are to accept the House version or open conference committee negotiations.
