I read a crazy ass book while I was in jail, I can't remember the name. But there was this wire net that people would wear on their heads, and they would press a button that would trigger the Euphoric centers of their brains, and different people had different experiences. And some people would just do dust instead.
But it was insane, and it's not the only book like that I have read. And then there are movies like "A Scanner Darkly" with the drug where once you do in once you are an addict, and the world is made up of those who have and have not taken it.
