it's what is known as "K" on the shitty little rave scene. it's a cat tranquilizer but they use it for other animals or old people who might die from regular anethesia. It will make you small and weak and I have read that it makes holes in your brain in the doses that people used to get messed up...bad shit don't mess with it.
Ketamine is cat tranquilizer, AKA "special k", is mostly just a party drug. somewhat new to the scene. It can be found or done in several forms. It can be snorted, and it is found in some types of extacy too-- I'm sure there's other forms as well. It's just another club scene drug.
I used it many times a few years back and it's a complete waste, I was young and stupid...lol. Slows everything down reeeeeeeeaaaaaaaalllllllllllllllllyyyyy slow.
If youre gonna do it, then I'd suggest injecting it IM. It's much cleaner, you use alot less, and it's more intense. Plus it doesn't put half as much toll on the body as snorting it does.
