Alright, so I remember watching a drug show a while back and the dude on it was shooting up what I believe to be horse tranquilizer?
It apparently completely shuts your central nervous system down, but your brain is still fully active. So pretty much you can't move and you see into another dimension. Also you apparently can't OD on this shit.
Now maybe I'm just high and it isn't horse tranquilizer. Has anyone heard of this? Is there any vendors that sell this shit?
That would be ketamine, from your post it sounds like you're pretty uneducated about the effects and risks, do more research and be sure you know what you're getting into. And FYI ketamine is used in pediatric medicine.
