Why Use The Word Entheogen?

I'm a enthusiastic supporter of the positive philosophical, social, and psychological potential of visionary psychoactive compounds.  Entheogens do something no other drugs can, and that mysterious something is inextricably related to the human sense of wonder that is formalized in the world's religions.

I'm particularly fond of the Santo Daime religion from Brazil, which is currently reaching out to cultures around the world. They provide a safe and supportive environment, low on dogma, in which to discover powerfully insightful states of consciousness. The strength and nature of the experience eliminates the chance of abuse.

Educate yourself with some of the following links!

PharmacotheonThe recommended comprehensive guide to the history, chemistry and psychology of entheogens is Jonathan Ott's Pharmacotheon. The Proemium (first chapter) is available online.

You used to be able to find any book on this subject from Mind Books... since 2003 your best bet it to following links to stores from the Erowid Library-Bookstore.

Other materials such as audio tapes can be had from Sound Photosynthesis. I enjoyed their tape series of Terence McKenna's True Hallucinations - Terence is always a compelling storyteller.

Some entheogen-related substances are covered in profuse and loving detail in Shulgin's PiHKAL.

Ayahuasca in particular is well-covered in the online book The Spiritual Uses of Psychoactives by the late Nicholas Saunders.
