My adult Daughter is currently a methodone user, about 8 mg right now, over the Memorial Day weekend she mixed her usual dose of methodone, oxycontin 20 mg (2-3) and then snorted some of this "bath sales" about one vial all in the same day, what are the dangers or what could have happened? She was up for three days, paranoid, and acting strangely as if she was speaking in tongues at time. I am so worried she is going to do something so stupid again like this. Patient is 29 years old, 280 lbs. female and about 5'10".
