DMT: The Spirit Molecule, by Dr. Rick Strassman.From the author’s blurb: “In 1990, I began the first new human research with psychedelic, or
hallucinogenic, drugs in the United States in over 20 years. These
studies investigated the effects of N,N-dimethyltryptamine, or DMT, an
extremely short-acting and powerful psychedelic. During the project’s
five years, I administered approximately 400 doses of DMT to 60
human volunteers. This research took place at the University of New
Mexico’s School of Medicine in Albuquerque, where I was tenured
Associate Professor of Psychiatry.

I was drawn to DMT because of its presence in all of our bodies.
Perhaps excessive DMT production, coming from the mysterious
pineal gland, was involved in naturally occurring ‘psychedelic’ states.
These might include birth, death and near-death, psychosis, and
mystical experiences. Only later, while the study was well under way,
did I also begin considering DMT’s role in the ‘alien abduction’
experience….

The Spirit Molecule reviews what we know about psychedelic drugs
in general, and DMT in particular. It then traces the DMT research
project from its earliest intimations through the maze of committees
and review boards to its actual performance.”
