Special K ~ Casey's Cell

I'm just looking over Casey's cell phone contacts, and she has someone in there called, "Special K." Now, I remember knowing that Special K was street slang for some drug, so I googled it and sure enough.:

1.	special k
	1. Ketamine 2. Often obtained by breaking into animal hospitals, this liquid-state tranquilizer can be poured over a mirror, dried, and diced into a powder ready for rave-happy snorting. Let's get tweeked on some special k at the rave tonight.
