Hard to come by because of the legal restrictions. The best sources I have seen:
Altered States of Consciousness edited by Charles Tart, 1969, Wiley.
Pharmako/Poeia by Dale Pendell, 1995, Mercury House.
They include pros and cons although it is obvious both guys are at least a little more pro than con. From Pendell’s book: “Smoking it occasionally makes you wise; smoking it a lot turns you into a donkey.” (p.199)
