Psychedelics 101: the honest starting point

What counts as a psychedelic

In everyday use, "psychedelic" covers a loose family of substances that temporarily change perception, mood, and thinking. The ones you'll encounter in legal settings today are psilocybin (the compound in certain mushrooms), ketamine (a dissociative anesthetic prescribed off-label), and MDMA (an empathogen still in the clinical trial pipeline for PTSD).

They are not interchangeable. They differ in duration, physical risk profile, drug interactions, and the kind of support a session requires.

The words you'll keep seeing

A short glossary makes the rest of the ecosystem far easier to navigate.

• Facilitator, a trained person who sits with you during a session. Not necessarily a therapist.
• Service center, a state-licensed location where supervised psilocybin sessions happen (Oregon, Colorado).
• Set and setting, your mindset going in, and the physical/social environment you're in.
• Integration, the structured work of turning an experience into durable change.
• Screening, the health review that determines whether a session is safe for you.

What the evidence supports today

Clinical research shows real promise for treatment-resistant depression, PTSD, and end-of-life anxiety, generally in tightly controlled settings with substantial psychological support. Outcomes outside those conditions are far less studied.

Treat any claim of a guaranteed cure as a red flag, regardless of who makes it.
