my buddy usually takes 2 80 mg oxycontin split in half orally through out the day or about 2-3 40 mg opana the same way. he just got a bunch of 60 mg morphine pills (little reddish w/ boxed M on one side 60 on the other) and was wondering if these morphines should be taken in the same amount or more or less than the oxys or opanas. he is taking these for pain relief not to get high or anything but knows morphine is different than the other two and was curious as what to take. he took half on one a few hours ago and still his back hurts. he already tried snoopin round the internet for answers and was unhappy with what he found. please help him.
