The Manual of Psychedelic Support is a comprehensive guide to setting up and running compassionate care services for people having difficult drug experiences at music festivals and similar events. The Manual grew out of the work of its original creators at KosmiCare, the psychedelic care service at the iconic Boom Festival in Portugal.

The Zendo Project is the author of the 4 Principles of Psychedelic Harm Reduction. They are an organization created by MAPS (the Multidisciplinary Association for Psychedelic Studies) which offers trainings, education, and support services at large scale music and arts festivals.

The MAPS Zendo Project’s Training Manual describes the four principles of psychedelic harm reduction:

• Create a safe space

• Sitting, not guiding

• Talk through, not down

• Difficult is not the same thing as bad
