That’s what happened the first time I did coke, in high school.
The only thing that had previously gone up my snoot was nose spray, when I had colds.
My then-BF brought some over only once, and was generous enough to also give my other visiting friends a couple lines each, on a plate on the dining room table.
He gave me mine first. I sniffed each in quick succession w/the corresponding nostril, and said “Wow!” as I straightened back up. I just kept going backwards, but my BF and friend Alex were right there and caught me! I was otherwise fine, and we laughed.
It wasn’t a rush in a conventional sense that caused it, either. It was really weird.
