Statnews: “As more states legalize medical and recreational marijuana, doctors may be replacing opioid prescriptions with suggestions to visit a local marijuana dispensary. Two papers published Monday in JAMA Internal Medicine analyzing more than five years of Medicare Part D and Medicaid prescription data found that after states legalized weed, the number of opioid prescriptions and the daily dose of opioids went way down. That indicates that some people may be shifting away from prescription drugs to cannabis, though the studies can’t say whether this substitution is actually happening or if patients or doctors are the driving force. “In this time when we are so concerned — rightly so — about opiate misuse and abuse and the mortality that’s occurring, we need to be clear-eyed and use evidence to drive our policies,” said W. David Bradford, an economist at the University of Georgia and an author of one of the studies. “If you’re interested in giving people options for pain management that don’t bring the particular risks that opiates do, states should contemplate turning on dispensary-based cannabis policies.”…”
