I think when we look back at the sixties, its a little bit too easy to say that the mass misuse is what led to the crackdown. In the follow up study that I did to the Good Friday experiment, Timothy Leary was the faculty sponsor in 1962, and it was about helping people who were religiously inclined to see if psilocybin would help them have mystical experiences. I did a follow up study 25 years later and I talked to the various people in the middle 80's, and what I learned from them is that they remembered their mystical experiences from psilocybin before, they still considered them valid, and they said there was a link between the unitive sense of connection; a little bit of their loss of fear of death, a little bit of empowerment, that led them to do work in social justice movements. Some talked about the civil rights movement, others talked about the environmental movement, some talked about the anti-war movement, the women's rights movement. So I think it's when psychedelics went right was the main reason that there was the crackdown and the reason that psychedelics went wrong was kind of the excuse; "We've gotta protect these people who are having these bad experiences, killing themselves, going to hospital emergency rooms", and there was a lot of that. At the same time though I think it was this association of people who were inspired by this sense of connection and the implications of that to challenge the status quo...
