John Horgan, author of Rational Mysticism: Dispatches from the Border Between Science and Spirituality, tries to rehabilitate the reputation of LSD and other entheogens over on Slate. Alas, he settles on the heinous prescription model–"Risks could be minimized by making these substances available only through licensed therapists, who can screen clients for mental instability and advise them on how to make their experiences as rewarding as possible. Some people might be prescribed entheogens for a specific disorder, such as depression or alcoholism. And just as drugs such as Prozac and Viagra are prescribed not just to heal the ill but also to enhance the lives of the healthy, so might entheogens."
It's a sad thing in the drug freedom debate that even most of those who present themselves as its defenders don't really believe in drug freedom.
