Demerol for sure. I figured that since it's a pure opioid (meperidine/pethidine) that i would get a much faster high snorting the shit. Little did i know that the stuff burns like fire. I snorted 2 50mg pills and since they are very small i did it in one line and as soon as it hit my nose it burned like someone had shoved a blow torch up my nose.
Thats something you only do once thats for sure.
I take this back actually. I once snorted diphenhydramine in a effort to get it to work faster to get rid of a godawful opiate itch i had. It worked faster all right but it damn near burned my nose off

It still did not burn nearly as much as the demerol though. So maybe it was still dumber snorting the demerol because there was absolutly no pay off on that.
