Hans,
Like the joke here about attending UC Berkeley in the late 1960's ("summer of love"): "if you can remember it, you weren't here."
By the way, I was (for a short time) a counselor for the BCIPD (Berkeley Committee for Information on Psychedelic Drugs): one of the great crimes, and wastes of good minds was the abuse of both legal, and illegal drugs by the youth of that time. These poor souls are now cluttering up the mental hospitals, or wandering the streets, and have become a burden to society.
Not that I have any solution to this (continuing) problem, but I at least had the chance to talk to people and try to convince them not to turn their brains into soup.
I am also fortunate I survived.
Austin
