-Sensory-Destruction
-	noticable.
-	Lowers resistance
-	Decreases stage speed tremendously.
-	Decreases transmittablity tremendously.
-	the drugs hit them so hard they have to focus on not dying
-
-Bonus
-	The body generates Sensory destructive chemicals.
-	You cannot taste anything anymore.
-	ethanol for extremely drunk victim
-	mindbreaker to break the mind
-	impedrezene to ruin the brain
