Frontier Science
Welcome to The Castalia Foundation. We are the world's only independent laboratory for psychedelic research. We are based on legally unceded territory which sets us above any other psychedelic-research group in the world: Our scientists are not owned by governments.
LSD Research
The Castalia Foundation is the only psychedelic research laboratory in the world engaged in the unrestricted study of LSD, mescaline and MDMA. The freedoms granted by our location, on legally unceded territory, means we are light-years ahead of the competition.
Empathogen Studies
We publish the world's most popular book on empathogen-entactogen healing protocols, MDMA Solo. Our free book has reached over one-million readers who are self-healing from severe trauma. We continue to study MDMA in our labs on unceded territory.
Psychedelic Review
First published by The Castalia Foundation in 1963, Psychedelic Review is the world's most widely-read psychedelic magazine. Through it, we seek to unite the fields of science, philosophy, and personal-experience in relation to all psychedelic medicines.
Established in 1963
We are the longest-running and most prestigious psychedelic research group in the world. Our books are published in multiple languages and have been read by millions of people worldwide. Click here to learn more about our founders.
Founded by Tim Leary
The Castalia Foundation team also includes Underground Press Syndicate members. We uphold the ethos of the Syndicate by preserving a free public-archive of The San Francisco Oracle. This was a psychedelic newspaper distributed in Haight-Ashbury in the 1960s.

Mind-control is the manipulation of the thought-processes of another human being, or group of humans, for the purpose of gaining power. This includes everything from ritual-abuse to ‘child-rearing’ techniques, ‘school’, the ‘news’ media, and advertising.


Psychedelics can be used to induce heightened neuro-plasticity in adults and accelerate the aquistion of new skills. Whether it's language-learning; drawing; or negotiation; learn how to harness the power of psychedelics for self-improvement and invention.

Psychedelics have been used for thousands of years by humans, it is only in our odd chapter of history that power systems have deprived us of a nutrient as essential as water. This book guides artists; engineers; and mathematicians, on their way to a partnership with LSD.
