A few years ago, in the early nineties, it was pretty big. Before E became mainstream, it was "all the rage". Anyway, one of my friends flipped out on it. Its a long story (amazing story actually), that Im not going to go into right now. Im just mentioning it to get to this point. Right after that happened, there was a documentary done by the tv show 48 hours, all about Acid and how it was "coming back" from the 60's or whatever. On that show, there was a guy who was on a permanent trip. It was very rare they said, but it does happen. They showed how for this poor guys entire life, he was stuck in a trip. He'd be talking to people, and see things as if it were a kalaidescope. Insane! Anyway, there is truth to it. I've seen it.
