I know a very prominent Rinpoche, whose name I shall not mention, that is very interested in ayahuasca, and I assure it's somebody you have lots of respect for. But you won't find any youtube clip about it because these things are done secretly and he seems to have a bit of a thing for secrecy. In fact, it's a pretty open secret, so I'm surprised that you wouldn't have heard about it. I'm sure others on here know who I'm alluding to, but are likewise not interested in naming names.
Well, you have me convinced!
And what, in Buddhas name, is an "open secret"? Either something is secret, or it is open.
And Alex Grey is a long time student of Namkhai Norbu, who put together a book called Zig Zag Zen, so if you really are interested, which I kind of doubt, you can find lots of Buddhist teachers discussing psychadelics in that book.
There are lots of deluded morons out there (including me) that are students of Namkhai Norbu (or any other Buddhist teachers), so this does not say all that much to me. Anyway, it is one thing to discuss psychedelics and another thing to endorse them.
The fact that the book has a foreword written by Stephen Batchelor, is published by Tricycle and is basically a vehicle to advertise Alex Greys artwork says a lot about what one is to expect. As for the other "expert" that wrote the preface (Huston Smith) well, his spiritual biography speaks for itself:
During his career, Smith not only studied, but practiced Vedanta (studying under Swami Satprakashananda, founder of the St. Louis Vedanta Center), Zen Buddhism (studying under Goto Zuigan), and Sufi Islam for more than ten years each. http://en.wikipedia.org/wiki/Huston_Smith
As a young man, he suddenly turned from traditional Methodist Christianity to mysticism, influenced by the writings of Gerald Heard and Aldous Huxley. In 1947, before moving from Denver to St. Louis, Smith set out to meet with then-famous author Gerald Heard. Heard responded to Smith's letter, inviting him to his Trabuco College (later donated as the Ramakrishna Monastery) in Southern California. Heard made arrangements to have Smith meet the legendary author Aldous Huxley. Smith was told to look up Swami Satprakashananda of the Vedanta Society once he settled in St. Louis. So began Smith's experimentation with meditation and association with the Vedanta Society of the Ramakrishna order.
Smith developed an interest in the Traditionalist School formulated by René Guénon and Ananda Coomaraswamy. This interest has become a continuing thread in all his writings.
Thanks to his connection with Heard and Huxley, Smith went on to meet Timothy Leary, Richard Alpert (Ram Dass), and others at the Center for Personality Research, where Leary was Research Professor. The group began experimenting with psychedelics and what Smith later called "empirical metaphysics." The experience and history of the group are described in Smith's book Cleansing the Doors of Perception. During this period, Smith was also part of the Harvard Project, an attempt to raise spiritual awareness through entheogenic plants.
During his tenure at Syracuse University, he was informed by leaders of the Onondaga Tribe about the Native American religious traditions and practices, which resulted in an additional chapter in his book on the world's religions.
In 1990 the Supreme Court ruled that the use of Peyote as a religious sacrament by Native Americans was not protected under the US Constitution. Smith took up the cause, as a noted religion scholar and, with his help in 1994, Congress passed the American Indian Religious Freedom Act Amendment, basically overturning the Supreme Court's decision.
Not really much there to tie him into Buddhism really, is there?
