Bruce Sterling's "The Hacker Crackdown" is a really interesting book that goes into detail about his involvement with the EFF and how it came about in the first place. It's a great read and available online at http://www.mit.edu/hacker/hacker.html
As far as I know most of the people involved with the EFF were big into psychedelics. E.g. I know Stewart Brand is on the board of directors, and he has written about his LSD usage many times. So has Mitch Kapor.
