most helpful answer ms contin is morphine and and opioid; oxycodone is another opioid so i doubt that a drug test will show up as negative.
my pain doctor did a saliva drug test on me last month and revealed use of oxycodone and he prescribes me ms cotin. i am also prescribed ult-ram 50mg 4-6 time daily. neurontin 600mg 3x daily. adderrall 30mg 2x daily seroquel 300 mg 1x daily. clonopin 2mg 3 times daily and also tizantadine 3 5 or 10 mg 3 at night and morpine 15 mg er 2x daily and morphine 15 mg regular 1 x daily. could this saliva drug test show up as a negative for non morphine use and a positive for oxycodone?
