I really, really, really don't want to encourage someone to do something they're not comfortable with, but seriously, plugging ? Mate, find someone who knows their shit, get fresh worx and main-line. It's the only way to go. If it's worth doing, it's worth doing right. Think about it: if an ambulance is called to help someone in pain, or a doctor/nurse at a hospital sees a patient in pain, they give them painkillers IV. You don't hear a doc go "quick, grind this up and inject it up ya butthole, stat!" I'm really not trying to be provocative, but if you're mucking around with oxy or morph or fentanyl or whatever, you come that far - go a little further and do it right.
