Can a Psychedelic From Toad Venom Help When Antidepressants Fail?
A study published in JAMA found that 5-MeO-DMT, a psychedelic from toad venom, significantly reduced symptoms in treatment-resistant depression patients. Administered as a nasal spray, the drug showed remission rates of 18-26% after a month. The study was funded by AtaiBeckley, recently acquired by Eli Lilly, which plans further evaluation. Side effects were mostly mild, with headaches and nausea being common.
