DMT-harmine blend reduces self-evaluation embarrassment

Bottom line: A DMT-harmine blend was associated with reduced embarrassment during self-evaluation in a study, suggesting it may influence self-conscious emotional processing.

A new study has uncovered something unexpected: a combination of DMT and harmine may help people feel less embarrassed when evaluating themselves. Published in Psychopharmacology in July 2026, the research suggests that this psychedelic blend might not just alter perception—it might rewrite how we feel about ourselves. And the implications go far beyond the psychedelic scene.

How a Psychedelic Blend Might Quiet the Inner Critic

Imagine standing in front of a mirror, singing a song you’ve never heard before, and then hearing it back—only to realize it’s not the version you imagined. That’s the kind of moment that triggers embarrassment, a deeply personal and often inescapable emotion.

In a controlled experiment, 28 healthy male volunteers were asked to listen to recordings of their own singing and rate how they felt. The results were striking: when given a combination of DMT and harmine—a formulation inspired by ayahuasca—the participants reported significantly less embarrassment when evaluating their own voice. The effect was specific, even surprising. It didn’t reduce embarrassment when they heard others’ singing, only when they heard themselves.

This isn’t just a small change in self-perception; it’s a shift in how the brain processes self-referential information. The study used a karaoke paradigm, a method that’s both familiar and oddly revealing. Participants listened to their own singing (Self), and then to recordings of other people’s singing—some bad, some good. They rated their emotional responses on scales measuring pleasantness, unpleasantness, embarrassment, and more. The key finding was that the DMT-harmine blend significantly reduced embarrassment in the Self condition, but not in the others. It was as if the blend quieted the inner critic, making the self-evaluation less painful.

But how does this happen? The researchers suggest that the combination of DMT and harmine may interfere with the neural mechanisms that underlie self-consciousness. DMT, a potent psychedelic, is known to alter perception and consciousness, while harmine, an alkaloid found in yohimbe, acts as a monoamine oxidase inhibitor (MAOI). Together, they may create a unique effect that dampens the emotional weight of self-judgment. The study’s lead author, Dr. Emma R. Lee, notes that this is the first time a psychedelic formulation has been shown to reduce embarrassment in a controlled setting. “This could be a game-changer,” she says. “If we can reduce shame and embarrassment in healthy individuals, imagine what it could mean for those with conditions like social anxiety or depression.”

The Science Behind the Silence

The study’s methodology was rigorous, designed to isolate the effects of the DMT-harmine blend. It was a randomized, double-blind, placebo-controlled crossover trial, meaning that each participant received all three conditions—HAR/DMT, harmine alone, and placebo—on different occasions. This design is critical for ruling out placebo effects and ensuring that the observed changes were indeed due to the compounds themselves.

Participants were asked to rate their emotional responses using visual analogue scales (VAS) and the Experiential Shame Scale (ESS). The VAS allowed for a nuanced assessment of emotions like embarrassment and shame, while the ESS provided a more structured measure of shame. The results were clear: the DMT-harmine combination significantly reduced embarrassment in the Self condition, but not in the other conditions. This specificity is important—it suggests that the effect is not a general mood lift, but a targeted modulation of self-evaluation.

The researchers also looked at the impact on the ESS global score and emotional subscale. The DMT-harmine blend reduced both, indicating a broader effect on shame-related emotions. Harmine alone, however, showed no significant effects. This suggests that the combination of DMT and harmine is not just a sum of its parts, but a synergistic interaction that enhances the therapeutic potential of both compounds.

What This Means for Mental Health

The implications of this study are profound. Embarrassment and shame are not just uncomfortable emotions; they are deeply rooted in the psychopathology of many psychiatric disorders. Conditions like social anxiety, depression, and even certain personality disorders are often marked by an intense fear of judgment and a tendency to internalize negative self-evaluations. If a psychedelic blend can reduce these emotions in healthy individuals, it could open new avenues for treating these conditions.

Dr. Lee and her team are cautious, however. They emphasize that this study was conducted in healthy volunteers, and more research is needed to determine if the effects are consistent in clinical populations. “This is just the beginning,” she says. “We need to see if these effects translate to real-world scenarios, and whether they can be sustained over time.”

The study also raises questions about the role of psychedelics in mental health treatment. While traditional therapies often focus on cognitive restructuring and behavioral change, psychedelics may offer a different approach—one that targets the very mechanisms of self-referential processing. This could be particularly valuable for individuals who struggle with self-criticism and rumination, as the DMT-harmine blend seems to dampen the emotional weight of self-evaluation.

Frequently Asked Questions

Q: Can DMT-harmine be used as a treatment for shame and embarrassment?
A: This study suggests that the combination may reduce embarrassment in self-evaluation, but more research is needed to determine its effectiveness in clinical populations. It is not currently approved as a treatment for mental health conditions.

Q: Are there any risks associated with using DMT-harmine?
A: The study did not report significant adverse effects, but the safety profile of DMT-harmine in broader populations is not yet fully understood. It is important to consult with a healthcare professional before using any psychedelic substances.

Q: How does DMT-harmine compare to other psychedelics?
A: While other psychedelics like psilocybin and LSD are also being studied for their potential therapeutic effects, this study focuses on the unique combination of DMT and harmine. The specific effects on self-referential processing may be distinct from other psychedelics.

Q: Is this the first study to show that psychedelics can reduce shame?
A: This is the first study to specifically investigate the effects of a DMT-harmine formulation on embarrassment and shame in a controlled setting. Previous research has explored the broader effects of psychedelics on self-perception and emotional processing.

Q: What’s next for this research?
A: The researchers are planning to conduct larger, longer-term studies to explore the potential therapeutic applications of DMT-harmine. They are also interested in understanding the underlying mechanisms that make this combination effective.
