Summary

Engaging in ayahuasca ceremonies can significantly enhance creativity, as evidenced by a study involving 40 participants who completed the Torrance Tests of Creative Thinking before and two days after a two-week ritual series. Results showed a marked increase in highly original solutions post-ceremony. Additionally, participants exhibited higher phosphenic responses, suggesting enhanced sensory activity linked to creativity. In contrast, 21 comparison subjects, with fewer recent psychedelic experiences, demonstrated lower baseline creativity levels. This highlights the potential of psychedelics in fostering creative expression through ritualistic practices.

Abstract

Studying the effect of psychedelic substances on expression of creativity is a challenging problem. Our primary objective was to study the psychome...

A Phase 1, Dose-Ranging Study to Assess Safety and Psychoactive Effects of a Vaporized 5-Methoxy-N,N-Dimethyltryptamine Formulation (GH001) in Healthy Volunteers

European Psychiatry  – June 01, 2022

Summary

A novel vaporized formulation of 5-MeO-DMT, tested on 22 healthy volunteers, demonstrated dose-related increases in psychedelic experiences without significant adverse effects. Participants reported heightened intensity on various scales, particularly after doses of 6, 12, and 18 mg. While cognitive functioning, mood, and well-being remained stable, individualized dose escalation led to the strongest psychoactive responses. Notably, vital signs were unaffected, and mild adverse effects like nausea resolved quickly. This approach may enhance therapeutic outcomes in treating depression with psychedelics.

Dark Classics in Chemical Neuroscience: Mescaline

ACS Chemical Neuroscience  – May 30, 2018

Summary

Mescaline, a psychedelic compound found in cacti like peyote and wachuma, has been used for over 6,000 years across the Americas. Despite historical prohibition due to misconceptions, its popularity has surged in recent decades. Mescaline’s effects primarily stem from its action as a 5-HT2A serotonin receptor agonist, while also interacting with 5-HT1A and α2A receptors. Its low potency has limited recreational use, yet growing interest in psychedelics may uncover therapeutic benefits and deepen understanding of hallucinogen pharmacology.

Abstract

Archeological studies in the United States, Mexico, and Peru suggest that mescaline, as a cactus constituent, has been used for more than 6000 year...

Isotopic DMT as a Probe of Spinorial Consciousness

Zenodo (CERN European Organization for Nuclear Research)  – March 11, 2026

Summary

A groundbreaking protocol aims to test the hypothesis that psychedelics like DMT influence consciousness through a radical pair mechanism at the serotonin 5-HT2A receptor. By creating isotopically labeled variants (13C-DMT and 15N-DMT), the study modifies nuclear spins while preserving key molecular properties. With a sample size of 100 mice, deuterium substitution shows a significant Kinetic Isotope Effect (∆m = +100%), while 13C and 15N substitutions yield negligible effects (∆m = +8% and +7%, respectively). Observed changes in psychedelic experiences could provide direct evidence for this mechanism.

Abstract

We propose a decisive experimental protocol to test the hypothesis that the psychedelic state involves the radical pair mechanism (RPM) operating a...
