WTF would happen if

what would happen if someone had a chemical that couased schizophrenia and somehow slipped enuf of it into food that millions of people consume. I know you could kill that many people but making them insane and having them alive, someone has to feed and shelter these guys.  wtf would happen.

you could cause them cancer by emitting asbestosis into the air near them. as long as its a dust. its fair game because they use light to damage peoples eyes. and they destroy nervs in peoples wrists, so why not cause them cancer??
