I'm sure most of you have heard of the case where a dude stripped naked and eat a hobo's face in Miami.
The police shot him 4 times before he went down.

They suspect that it had to do with a drug called "bath salts".
I looked it up and it seems to be any chemical compound made from a variety of ingredients which resemble things like meth, extacy, etc...
The effects remind me of PCP from the way they are described.
I faintly remember hearing of cases where people eat their own fingers, bashed their heads into walls and crap like that

My question is this,
What do people smoke whatever they can get their hands on?
Spice (one of the lamest drugs I've ever seen) even seems to be responsable for strokes.

I'm a working kind of person, so drugs are out for me.
But wouldn't one at least want to know whats in a particular drug and what its supposed to do to before they try it?
