If you are unfamiliar with Ketamine, also known on the street as Special K, consider yourself lucky. This dumb drug is enjoying something of a renaissance recently, as The Situation's dumb friend The Unit (really) just got arrested for possessing a ton of it, and scientists say that it cure depression almost instantly. 

Yeah. I don't buy it. 

Ketamine is turned into its street form by tweaking horse or cat tranquilizer into a drug similar to PCP in that it creates a "dissociative anesthetic" state. In other words, it turns you into a complete raging lunatic. It's commonly considered a "club drug" in that a loud, flashing dance club is probably the only place you can take it and not seem like a total psychopath freak show. It's like MDMA in that you can be easily mesmerized by the lights and sounds around you, but it's unlike MDMA in that it's a tranquilizer, so you're losing energy by taking it, instead of the other way around. 

Oh yeah. Then there's the fabled "k-hole" when you take too much. A k-hole occurs when you take way too much ketamine and just go apeshit. Only you can't move. Your body is unable to move, you start drooling, but in your mind, you lose all sense of time and hallucinate complex experiences that never actually happened. 

Remember, this is something used to put horses to sleep. I'm not saying that other street drugs are a walk in the park, but this seems to be a fairly dangerous one to use even a little. 

Maybe grab a drink instead? I mean, does this look like a good time to you?
