What is MDMA?
A non-classical psychedelic empathogen, chemically distinct from classic psychedelics like LSD or psilocybin, primarily studied in a clinical-therapy context for PTSD.
Is MDMA-assisted therapy FDA approved?
Not yet. The FDA rejected the first application (then Lykos Therapeutics) in 2024. A resubmission is now underway under a new name, Rysanso, alongside a new VA veteran trial. See our coverage.
Is MDMA legal?
Schedule I under the Controlled Substances Act — illegal outside approved clinical trials.
What does MDMA do?
Increases release of serotonin, dopamine, and norepinephrine, producing entactogenic effects — increased sociability, emotional openness, and reduced fear response — which is the basis for pairing it with talk therapy for trauma.
