As a former hippy of the early seventies I can only say that the "hippie movement" back then was destined for failure. The ideology of love and peace was too far from the mainstream. And there wasn't alot of cohesion or Ieadership. I don't really believe you can label the drugs of choice back then as "Us" or "Me." I frequently tripped on LSD isolated in my upstairs bedroom with Black Sabbath wailing and my eyes locked on the vivid black lite posters. But I also enjoyed dropping acid or psilocybin mushrooms with friends.
My part of the Ozarks still has a large population of hippies who migrated here in the seventies. We remain laid back and can still appreciate the effects of a good high. Only now moderation seems to be the key.
