^ Ismene, you are profoundly incorrect.
I see.
How exactly did you manage to go back in time and meet "most of the people who took acid in the 60s" before and then after they took acid in order to pronounce that they were "wankers" (whatever the hell that is supposed to mean) both before and after?
So can you point to any of these people who'se life it allegedly changed and what they did as a consequence? Do you think the majority of people who took acid really changed in any way?
There's certainly plenty of people like Jerry Rubin who took acid in the 60's and in the 80's became hardline corporate capitalists.
What do you make of the study by MAPS that a large majority of people who were given a strong dose of Psilocybin said it gave them a life-changing spiritual experience?
I'd say come back in 5-10 years and ask them again. Psilocybin can certainly give a life-changing spiritual experience the problem is how you adapt a "life-changing spiritual experience" into everyday life. And remember this study was done with people who were depressed and dying. The vast majority of people who drop acid don't have cancer and arn't dying - being terminally ill adds something to a trip.
Incidentally when Timothy Leary did the same thing back in the 60's he had to fake the conclusions because the recidivism rate for the psilocybin taking prisoners was the same as for any other prisoner.

Let me make you happy and then we'll talk meaning. :D Not being sarcastic, that was a great award-worthy post, thanks.
