DMT-harmine blend reduces self-shame in social evaluation tests

Bottom line: A DMT-harmine blend was associated with reduced self-shame during social evaluation tasks in a lab study involving 28 men.

A man sits in a dimly lit lab, listening to a recording of his own singing. His face is pale, his hands clenched. He rates how embarrassed he feels. Hours later, he takes a pill and listens to the same recording again — this time, the emotion is gone. This isn’t a movie scene. It’s a study of 28 men, where a combination of DMT and harmine — the key ingredients in ayahuasca — cut self-shame during a task that mimics social judgment. But what does that mean for the rest of us? And why did it work only for the self, not for others?

The Lab That Made You Feel Less Embarrassed

In a quiet lab, 28 healthy men sat in front of a screen, listening to their own singing. They rated how embarrassed they felt, how funny it was, and how objective the performance seemed. Then, they took a pill — either a combination of DMT and harmine, harmine alone, or a placebo. An hour later, they repeated the task. The results were striking: the DMT-harmine mix cut self-shame by nearly 17 points on a visual scale, while harmine alone had no effect. The placebo group felt the same as before.

This isn’t just a curious finding. It suggests that the combination of DMT and harmine may have a unique effect on how we process self-referential emotions — like shame and embarrassment — during social evaluation. But why did it only work for the self, not for the “other bad” or “other good” conditions? And how does this relate to the broader world of psychedelics and mental health?

The study used a karaoke paradigm, a clever way to simulate real-life social situations. Participants were exposed to their own singing, as well as recordings of other people singing — both bad and good. The idea is that self-judgment is more intense than judging others, and the emotional response is more personal. The researchers measured this with visual analogue scales, where participants rated their feelings on a continuous line. The DMT-harmine group reported significantly less embarrassment in the self condition, but not in the other conditions.

This finding is important because self-shame and embarrassment are central to many mental health issues. They contribute to social anxiety, depression, and even eating disorders. If a psychedelic blend can reduce these feelings in a controlled setting, it raises the question: could it help people in real life?

How DMT and Harmine Work Together

DMT and harmine are both alkaloids, but they work differently. DMT is a psychedelic compound that acts on serotonin receptors, particularly the 5-HT2A receptor. It’s known for its intense hallucinogenic effects, but in this study, its role was more subtle. Harmine, on the other hand, is an MAO inhibitor. It prevents the breakdown of DMT in the body, allowing it to reach the brain. Together, they form a potent combination that may enhance the psychoactive effects of DMT while reducing some of the side effects.

The study’s design was meticulous. It was a randomized, double-blind, placebo-controlled crossover trial, meaning each participant took all three conditions — DMT-harmine, harmine alone, and placebo — in random order. This helped eliminate bias and ensure the results were reliable. The sample size was small — only 28 men — but the effect size was large. The reduction in embarrassment was over 16 points on a scale, which is significant in psychological terms.

What’s even more interesting is that harmine alone had no effect. This suggests that the combination of DMT and harmine is necessary for the observed changes. The researchers also found that the DMT-harmine mix reduced the Experiential Shame Scale (ESS) global score and the emotional subscale. This means that the effect wasn’t just on embarrassment, but on a broader measure of shame.

This finding is not just about reducing self-shame. It’s about how the brain processes self-referential information. The study used a karaoke paradigm to simulate social evaluation, which is a common source of self-consciousness. By reducing the emotional response to self-judgment, the DMT-harmine mix may help people feel less anxious in social situations.

Why It Works Only for the Self

One of the most intriguing findings of the study is that the DMT-harmine mix reduced self-shame but not shame related to others. This is a key distinction. Self-referential emotions are more intense and personal, and they are often linked to deeper psychological processes. The study’s use of a karaoke paradigm allowed the researchers to isolate self-judgment from social comparison.

This is important because self-shame and embarrassment are more complex than just feeling bad about oneself. They involve a sense of self-worth, social identity, and the internalization of external judgments. The DMT-harmine mix may alter how the brain processes these internalized judgments, making the self-feel less harsh.

But why didn’t it work for the “other bad” or “other good” conditions? The answer may lie in the nature of social comparison. When we judge others, we’re often using a different part of the brain — one that’s more analytical and less emotionally charged. The DMT-harmine mix may not affect this part of the brain as much, which is why the effect was only seen in the self condition.

This distinction is crucial for understanding the therapeutic potential of the DMT-harmine mix. If the drug can reduce self-shame without affecting social judgment, it may have applications in treating conditions like social anxiety, where the focus is often on self-evaluation rather than social comparison.

Frequently Asked Questions

Q: Can DMT and harmine be used to treat mental health conditions?
A: The study suggests that the combination may reduce self-shame and embarrassment, which are key symptoms of conditions like social anxiety and depression. However, more research is needed to determine its therapeutic potential in clinical populations.

Q: How does DMT work in the brain?
A: DMT acts on serotonin receptors, particularly the 5-HT2A receptor, which is involved in mood regulation and perception. Harmine, as an MAO inhibitor, prevents the breakdown of DMT, allowing it to reach the brain and produce its effects.

Q: Why did the DMT-harmine mix only reduce self-shame and not shame related to others?
A: The study suggests that self-referential emotions are processed differently in the brain, and the DMT-harmine mix may specifically target these processes. Social comparison and judgment of others involve different neural pathways, which may not be affected as much.

Q: Are there other studies on DMT and mental health?
A: Yes. Research on DMT and other psychedelics is growing, with studies exploring their potential in treating depression, PTSD, and addiction. However, the long-term effects and safety of these compounds are still under investigation.

Q: What are the limitations of this study?
A: The study was conducted on a small sample of healthy males, so the findings may not generalize to women or people with mental health conditions. It also did not include long-term follow-up or explore the mechanisms behind the observed effects.
