ERIE provides comprehensive services for individuals interested in entheogens and psychedelics

What is an Entheogen?

The word “entheos” (Greek for “god within”) was once used to describe a state of rapture and possession by a metaphysical force. Entheos could be manifested in multiple ways, including prophetic seizures, erotic passion, creative energy, as well as ingestion of substances.

By combining “entheos” with “gen” (an “act of becoming”), Ruck and colleagues proposed the term “entheogen” to describe shamanic and ecstatic possession induced by the ingestion of mind altering substances.

— Ruck et al 1979


The Entheogenic Research, Integration, and Education (ERIE) mission:

1) Review and conduct research on the use of traditional plant medicines, and their modern analogs, for creativity, healing, personal growth, and spiritual exploration;

2) Develop integration methods that combine new research with existing, tested practices to help people incorporate extraordinary experiences into their lives;

3) Articulate a new educational paradigm that honors and draws upon the vast Indigenous knowledge of plant and fungi kingdoms, then envisions new applications of it within contemporary Western contexts; and

4) Create a forum for the responsible discussion of these topics.

      ERIE was founded in 2012 by graduate students at the California Institute of Integral Studies (CIIS) in San Francisco. ERIE members conduct research on entheogens (psychedelics); we host peer integration circles for those seeking to comprehend and incorporate complex and challenging transpersonal experiences into their lives; and we sponsor lectures, panel discussions, conferences, and round table dialogues to educate the public about the potential of entheogenic medicines. ERIE is a California exempt non-profit corporation and we have applied and await our determination letter for our 501(c)(3) status.
