What this is

Palhano-Fontes 2019 TRD RCT showed single dose ayahuasca beat placebo at 7 days. DMT injection trials (Small Pharma/Cybin) for depression ongoing. MAOI component creates tyramine/serotonin-syndrome risk with many foods/drugs. 'Extended-state DMT' IV infusion protocol is a research frontier.

Mechanism

DMT (N,N-dimethyltryptamine) is 5-HT2A agonist; orally inactive without MAOI; ayahuasca pairs DMT-containing Psychotria with harmala MAOI-containing Banisteriopsis; short-acting when vaporized/injected

Dose & route

Ayahuasca: traditional decoction in ceremonial context; DMT: 15-40 mg vaporized, 0.2-0.4 mg/kg IV in research
