You are right that the effects of this drug are shocking.
In what way?
The on set is very sudden. Not like a regular drunk. It's completely immobilizing. The instance that I saw, the girl hit the ground very hard, as if someone clunked her on the head. After going out, she was paralyzed to the point of being unable to speak beyond a dim mumble, yet her eyes were open, responded to light, etc.
The medicos who responded knew what it was immediately.
You are very drunk very fast and your body is unable to metabolize it or get rid of it the way you would alcohol.
You are giddy, suggestible and (in the case I saw) very amorous.
Higher doses put you into a waking coma where you are awake but not able to do much under your own power.
