ha for whatever reason we payed a mormon kid in our physics class to snort plaster of paris. That could not have been could for the sinuses.
For my vote ive got three choices (yea i was that dumb before i found bluelight...moral of the story...never believe idiots) 2CI hurt really bad for like 30 mins straight. Was still hurting when I was fully coming up to fully up. Ill have to agree with the other dumbass:D that snorted prozac because fuk dude...omg it hurt so bad. The other substance i snorted by accident. I am not at all sure of what it was, but i did later find out that it was some kind of antibiotic. I had bought the pills that were supposed to be oxycodone. I should have known better for sure, but alas i was withdrawing. Within seconds of snorting the substance my entire right sinus cavity became completely seized up and stopped up. I mean my nose was completely stopped up, like i had snorted cement for hours upon hours. I learned an important lesson from that night. Always look up the pills your taking, no matter how theyre being taken.
One substance that is not a drug but that i accidentally sucked up my nose was hydrogen peroxide. Holy shit cakes! I was going to take a drink out of a cup of "water" that was in my friends bathroom. Turned out it was h. peroxide and some of it went up my nose. That is one shock i will never forget, even though i was so high i didnt realize i was about to drink h. peroxide. Seemed like it completely dried up my sinus for months, if it has ever fully recovered. Harm reduction folks...its worth its weight in heroin!
