Dude, if you had broken ribs, they can't deny you pain medication. If you walked into the emergency room suffering from chronic pain every day, they would get you some pain medication. They probably checked for drugs while you were unconscious to check for drug interactions etc. I still don't know why they would waste their time checking for weed.

You should try to educate your doctor to the benefits of MJ. If you are old tell him you use it for aches and pains, if you are young tell him it relaxes you so you can study better. Don't just let THEM tell YOU that it's bad for you and you have to stop. Peace.
