Qualitative insights into psilocybin and LSD experiences: Enhanced connection and emotion processing reported by Spanish-speaking survey respondents

Psychedelics November 15, 2025 Meghan DellaCrosse, Shoval Gilead, Rafael Lancelotta et al.

Serotonergic psychedelics like psilocybin and LSD have shown potential therapeutic benefits for mental health conditions, including depression, PTSD, and addiction. However, research remains limited due to regulatory barriers and a lack of diversity in study populations. Spanish-speaking individuals, despite their significant global and U.S. presence, are underrepresented in psychedelic...

Journal of Psychoactive Drugs July 14, 2023 Christopher Timmermann, Aki Nikolaidis, Alan K. Davis et al. 4 citations

This study translated and tested the psychometric properties of acute psychedelic effects measures among Spanish-speaking people. The Psychological Insight Questionnaire (PIQ), Challenging Experiences Questionnaire (CEQ), and Mystical Experiences Questionnaire (MEQ) were translated before being incorporated into a web-based survey. We recruited native Spanish-speakers (N = 442; Mage = 30.8, SD...

Reactivations after 5-methoxy-N,N-dimethyltryptamine use in naturalistic settings: An initial exploratory analysis of the phenomenon’s predictors and its emotional valence

Frontiers in Psychiatry November 29, 2022 Ana María Ortiz Bernal, Charles L. Raison, Rafael Lancelotta et al. 26 citations

Background The psychedelic 5-MeO-DMT has shown clinical potential due to its short duration and ability to induce mystical experiences. However, a phenomenon known as “reactivations” (similar to “flashbacks”) is a poorly understood and frequently reported phenomenon which appears associated with 5-MeO-DMT use and warranted further investigation. Aims This study examined whether differences in...

No Detectable Electroencephalographic Activity After Clinical Declaration of Death Among Tibetan Buddhist Meditators in Apparent Tukdam, a Putative Postmortem Meditation State

Frontiers in Psychology January 28, 2021 Dylan Thomas Lott, Tenzin Yeshi, N. Norchung et al. 18 citations

Recent EEG studies on the early postmortem interval that suggest the persistence of electrophysiological coherence and connectivity in the brain of animals and humans reinforce the need for further investigation of the relationship between the brain’s activity and the dying process. Neuroscience is now in a position to empirically evaluate the extended process of dying and, more specifically,...

A comparison of reactivation experiences following vaporization and intramuscular injection (IM) of synthetic 5-methoxy-N,N-dimethyltryptamine (5-MeO-DMT) in a naturalistic setting

Journal of Psychedelic Studies March 25, 2020 Malin V. Uthaug, Rafael Lancelotta, Ana María Ortiz Bernal et al. 25 citations

Abstract Background Previous research suggests a therapeutic potential of 5-methoxy-N,N-dimethyltryptamine (5-MeO-DMT). However, online anecdotal reports have described a phenomenon following cessation of the acute effects of 5-MeO-DMT use which has been termed reactivation (i.e., re-experiencing [“flashback”]). To date, no research has investigated whether different routes of administration...
