Psychedelic mushrooms are powerful medicine. They have a psychoactive effect which alters brain chemistry and helps neurological disorder. We can see that in the paper. But then so do anti-depressants.
I believe the key difference between plant medicines like mushrooms, Peyote, Ayahuasca and others and clinical mood altering medicine is within the ecstatic experience. It is one to thing to have a pill lead you to an empirically more "healthy" brain. It is quite another to embark on a deep, introspective vision which provides a narrative to match the chemical benefit.
I volunteer as a guide within Ayahuasca ceremonies in Peru. Many turn to Ayahuasca as a last resort for depression, PTSD, sexual trauma, and much more. I have seen people in ceremony live through what they interpret as a hellish exorcism, an active exploration of their lineage, or a direct confrontation and resolution of their deepest emotional and spiritual trauma. These people often undergo significant positive transformation after the experiences.
These profoundly "real" experiences appear to be essential to the healing process.
We are creatures of story and psychedelics can help write a _most radical_ chapter of recovery.
