I looked over the bios of the faculty at the Berkeley graduate theological union recently (in hopes of finding someone to talk to about these issues), and was disappointed to find that they seem to have almost no one with an interest in mysticism or psychedelics -- something a little surprising considering Berkeley's storied psychedelic past and radical reputation. They seem to be generally pretty conservative in theological interest and academic (in the ivory tower, bookish, non-practical sense). I hope that I was mistaken or that it changes as they become more educated and aware, and maybe even acquire some personal experience with psychedelics.
I personally do not understand how someone interested in religion could not be interested in mysticism or psychedelics, as they almost literally put the golden chalice in your hands and can bring to life all those things many academics merely read about.
Even if mystical experiences occasioned by psychedelics aren't genuine (as Zaehner argued in the 60's -- arguments likely to be rehashed endlessly), they at the very least raise many questions of supreme religious importance and countless people do interpret their experiences in a religious/spiritual light.
With church attendance falling for decades now, with more and more people disavowing religious affiliation and identifying themselves as "spiritual but not religious" or outright atheist, you'd think more religious people and academics with a theological bent would take an interest in substances that pretty reliably cause mystical experiences, but they seem to be mostly ignored and the religious side of academia mostly seem content to cede the field to the scientific and medical establishment.
I hope the BCSP and other forward-thinking organizations can start opening people's eyes to the religious potential of psychedelics, because feedback and insight from religious professionals of all kinds could be very valuable.
