Ketamine and esketamine have a different clinical and regulatory history from psilocybin or DMT. Ayahuasca and 5-MeO-DMT connections are investigational and earlier-stage. A medicine appearing here means it has a meaningful research or clinical connection to depression, not that every formulation is approved or appropriate.

Research spans established dissociative treatment and experimental classic-psychedelic approaches. The evidence and experience differ substantially by medicine.
Medicines appear here because of current research, a specific established clinical context, or sustained public interest. Inclusion does not establish approval, suitability, safety, or effectiveness for an individual.
01 / START HERE
A condition is a starting point, not the whole story.
Depression is not one uniform experience or one research population. Studies may focus on major depressive disorder, treatment-resistant depression, recurrent depression, or depressive symptoms within another condition. Those distinctions affect what a result can—and cannot—say.
Before centering a medicine, clarify the kind and duration of depression, current medications, bipolar-spectrum or psychosis history, suicidality, previous treatment, physical health, support, and what care is available after an experience.
