A single dose of dimethyltryptamine (DMT), a naturally occurring psychedelic, significantly reduced symptoms in people with major depressive disorder, according to a clinical trial led by researchers at Imperial College London. The study found that participants with depression who received DMT showed greater reductions in symptom severity compared to those who received a placebo.
Trial Design and Results
The trial enrolled thirty-four patients with moderate to severe depression and a history of at least two unsuccessful treatments. Half received a single intravenous placebo over 10 minutes, while the other half received a 21.5 mg dose of DMT. Symptom severity was measured using the Montgomery-Ångsberg Depression Rating Scale (MADRS) before and after treatment. Two weeks after the initial dose, the DMT group showed less symptom severity compared to the placebo group. Six months later, some participants reported that the antidepressant effects were still present. The study was published in the journal Nature Medicine, and no serious adverse events were reported.
Mechanism of Action and Limitations
According to Dr. Marc Siegel, Fox News senior medical analyst, “DMT probably works for depression by taking you out of your downhill spiral while at the same time altering brain chemistry in a way to promote the release of hormones, especially serotonin, but also dopamine.” However, DMT’s efficacy appears dependent on the intensity of the actual psychedelic experience it generates, which varies from person to person.
The researchers noted limitations including a lack of ethnic diversity in the study and the exclusion of participants with a history of serious suicide attempts. Lead study author David Erritzoe emphasized that “this is a trial that sits in the early phase of specifically developing DMT therapy for depression, so larger trials are required as next steps.” He noted that it is currently difficult to access DMT treatments outside trials because research is still ongoing. For people seeking alternatives, he recommended “ketamine-assisted therapy, done in a thoughtful way with good therapists involved” as an option while new treatments undergo testing.
