"I believe that if people would learn to use LSD's vision-inducing capability more wisely, under suitable conditions, in medical practice and in conjunction with meditation, then in the future this problem child could become a wonderchild." -- Albert Hofmann (1906-2008)

Wasn't it Grace Slick who said she used to believe that if everybody dropped out and read a bunch of books the world would be a perfect place? But then we grow up and see that drugs do nothing but magnify our own psychosis (maybe peppering it sometimes with hints and glimmers of something magnificently transcendental), and that no problem is ever going to be solved, in this world or in the next, by the magnification of our own psyches. We get weary of drugs, weary of our own psycho-drama, and ready for reality (a reality more real than the daily-babble monkey-mind of our 'headache gray', fluorescent lit chattersphere)?
But that's not to disparage Mr. Hofmann -- he was a brave man, I think.
