Psychedelic Synonyms

Exactly what we call these substances has changed over time.  For some, it is a plant “medicine”, for others it emulates mystical experiences (mysticomimetic), and even others it induces profound emotional states of being (Empathogen).

What’s in a name?


As an interesting note in understanding our lineage, we have to look at some of the terms that we use.  In our literature alone we use different terms such as “psychedelic” and “entheogen”.  Exactly what we call these substances has changed over time.  For some, it is a plant “medicine”, for others it emulates mystical experiences (mysticomimetic), and even others it induces profound emotional states of being (Empathogen).  The words have changed over time.  Scientists in the 1950s preferred the term “Hallucinogen”, the counter-culture movement adopted “psychedelic” and then later was discarded to separate ourselves from the “hippie era” and some adopted “Entheogen” or “seeking the divine within”.  How we view these substances is often different for different people.  For some its a clinical aid, for others spiritual and/or divinity, and for others a medicine or catalyst.

Which is right?

Perhaps none, or all of them, or they change over time for the user.  And perhaps, like the effects of substances themselves, they can never be defined in a clear way.

In honoring of the diversity of paths, approaches and backgrounds found within Psychedelics in Recovery, we provide here a comprehensive list of the terms, along with their definitions, origins, and, where possible, information on when they were first used or who coined them.
