Psychedelic DMT—part of ayahuasca—shows antidepressant promise in small clinical trial

LSD-like drugs may inspire new antidepressants

LSD and psilocybin have shown promise as antidepressants. Using a virtual library of similar chemical compounds, researchers determined via animal studies that two molecules inspired by LSD have antidepressant effects without any associated hallucinogenic experience. These molecules were found to be 40 times more potent than the common antidepressant fluoxetine, also known as Prozac, with antidepressant effects lasting up to 21 days.

Psychedelic side effects, including worsening mental health for some patients, give pause

This article explores whether the therapeutic potential of psychedelic drug use is really as good as current research suggests.

Psychedelics are being fast-tracked for research after a 2026 executive order

Many such compounds (including LSD, psilocybin, and more) are classified as Schedule I drugs—illegal to possess and federally regarded as having no medical use. Researchers say such restrictions have created significant hurdles for formal clinical trials. With this executive order, the FDA will enable work particularly focused on depression, PTSD, and alcohol use disorder.

Mixed reality technologies may help treat depression
