The only way morphine will show up in your urine is if you take the morphine. You're obviously not taking it, or you're running out early and showing up at the doctor's office every month detoxing. Either way, they will catch up to you eventually. If you go to another doctor in the same State you'll have to tell them you were thrown out of the previous doctor's office because they will find out immediately by running a board of pharmacy report. This report tells them what opiates you've been prescribed and who prescribed them. Stop playing games with these people and be honest about your situation. You'll eventually run out of legitimate options for pain control if you truly suffer with chronic pain.
Healingtouch, I am glad that you found out you are not metabolizing the morphine correctly.
I have just heard about this cheek swab which is supposed to tell the doctor what is the best type of pain medication for your body
