just rail the whole thing and get really high.
first time i did oc other than eating 10 mg once before I railed a whole 80 and it was one of the most awesome things ever
I don't mean to be a jerk, but are you stupid?
The OP is still relatively new to opiates, having taken oxycodone only a handful of times, so what would make you think that taking double his recreational dose would ever be a good idea?
Insufflated oxycodone
does have a lower bioavailability than when it's taken orally, so the OP may need to dose just a bit more than 20 mg, and he may end up sniffing the whole thing after all, but in the interest of harm reduction, I would still recommend that he begin by sniffing what he knows to be a safe and recreational dose of 20 mg.
But anyway, it sounds to me, OP, like you have the old formula oxycontin, so to sniff it simply grind it down into a powder using a metal hose clamp or fold it up in a dollar bill and use the end of a lighter or something to smash the hell out of it. Then, rack up your lines,find a straw and commence sniffing. Taking the coating off is really just a matter of personal preference. You can do this by putting the pill in your mouth, sucking on it for a few seconds, and then simply wiping it off with a paper towel.
