Short Wave

What If You Took The "Trip" Out Of Ketamine?

08 Apr 2025

Description

What if you could get all the potential benefits of ketamine without the "trip"? For part two of our series on psychedelics, we look at how some researchers are trying to disentangle the "trip" from the drugs' effects on the brain — and why the answer could help direct the future of psychedelic research. (Spoiler alert: People generally know if they're tripping or not.) This episode: a researcher navigating this challenge by putting his patients to sleep. Catch the rest of this series on psychedelics and related drugs this week by following us on Spotify and Apple Podcasts. Have other questions about psychedelics and the brain?

Definitely check out that episode if you missed it, but also this one will make sense without it. Rachel, you touched on one thing in that episode that we're going to go a little deeper on today, and that's the challenge of studying these drugs.

Exactly. So when we're talking about how drugs like psychedelics and ketamine work, or if they work at all, what the heck are we actually talking about?

65.319 - 77.675 Boris Heifetz

There's the drug. There's the trip. And then there's all these non-drug factors, meaning the stuff at the beginning, like the expectations you set, the hope you have, the lessons you learn.

79.436 - 99.047 Rachel Carlson

This is Dr. Boris Heifetz. He's an anesthesiologist and neuroscientist at Stanford University. And he told me that researchers have been wondering for a while if the trip that comes with a lot of psychedelics, this journey or experience, is really important, or if it's just this unnecessary byproduct when it comes to making people feel better.

99.807 - 116.41 Boris Heifetz

So a lot of people actually have been talking about this for years, like, well, what if you just knock someone out? What if you eliminated experience during a psilocybin trip or during one of these drugs in this broad class, in which I'll include ketamine for a

So that's exactly what Boris did.
