Researchers are studying psychedelics as a possible treatment for conditions like depression, PTSD and substance use disorders. But they don't know exactly how these drugs work.

Getting the answer to this question is especially difficult when people often take psychedelics like LSD and psilocybin for the "trip."

This week on Short Wave, we're talking to researchers about how they're trying to untangle the effects of this "trip" from the ways psychedelics might change the human brain ... and why the answer could help direct the future of psychedelic research.

Catch the rest of this series on psychedelics and related drugs this week by following us on Spotify and Apple Podcasts.
