My pain management doctor recently gave me a urine drug test and i tested positive for opioids (morphine) to be exact. My prescription from him for the past 30 days was supposed to be 1 10mg percocet 4x a day. Unfortunately I take ALOT more than that. I was taking throughout that month a combination of oxycontin 60mg and oxycodone 30mg. Is this the reason he said I tested positive for the morphine and opioids? I thought that because I was supposed to be taking 4 10mg percs a day that I would have been fine taking his drug test. Is it because of the amount of oxycodone I had taken throughout the entire month?
