I have a friend who I care for deeply.  I am very naive when it comes to drugs.  He was taking Tramadol.  According to him it was something to help him sleep.  Then he fell and broke his leg.  His doctor gave him 120 OxyContin pills.  What doctor does this?  Now my friends is addicted to OxyContin.  He became very aggressive and abusive.  I had to back away.  I don’t know how to help him unless he wants help.  What can I do.
