My Husband had the same issue when the Medical Marijuana laws recently passed in Florida. He had to change Doctors. He and I had the same orthopedist and PM doc’s for years, but at their facility, they decided to opt out of allowing medical marijuana patients to be prescribed opiates. I know things change State by State, but basically here, he had to get his medical marijuana card, then find a PM Doctor that would treat them with Opiates. Not as hard as it sounds really. It can take a couple of months, but for some it is very much worth it ...
Good luck
