RESUMEN

Psychedelics have a complex history marked by traditional use among indigenous cultures, early scientific interest, and subsequent prohibition. Despite their classification as controlled substances, recent decades have witnessed a resurgence of research into their therapeutic potential for various mental health conditions. However, most studies have focused on controlled clinical settings, leaving a significant gap in understanding how these substances are used in naturalistic contexts, particularly in Latin America. This study investigates the regular use of macrodoses of psychedelics among Latin American adults. We aimed to characterize the sociodemographic profiles, consumption practices, and subjective effects experienced by individuals who use psychedelics regularly. Data were collected via an online survey from 4,270 participants across several Latin American countries. Results indicated a diverse user base with varied motivations, predominantly psychological and spiritual well-being. The most frequently used substance was psilocybin mushrooms, with significant associations found between demographic variables and specific psychedelics used. The study provides new insights into the naturalistic use of psychedelics in Latin America, highlighting the need for informed, safe, and legal use frameworks.

RESUMEN

Alcohol is a harmful drug, and reducing its consumption is a significant challenge for users. Furthermore, alcohol dependence is often treatment-resistant, and no completely effective treatment model is available for chemical dependence. Classic psychedelics, such as LSD, psilocybin, and ayahuasca have been used in different clinical and pre-clinical trials, demonstrating promising pharmacotherapeutic effects in the treatment of treatment-resistant psychopathological conditions, such as addiction, especially related to alcohol dependence. In this work, we conducted a narrative review of the emerging research regarding the potential of psychedelics for alcohol use disorder treatment. Psychedelic substances have demonstrated potential for treating drug addiction, especially AUD, mostly by modulating neuroplasticity in the brain. Given that serotonergic psychedelics do not produce physical dependence or withdrawal symptoms with repeated use, they may be considered promising treatment options for managing drug use disorders. However, certain limitations could be found. Although many participants achieve positive results with only one treatment dose in clinical studies, great inter-individual variability exists in the duration of these effects. Therefore, further studies using different doses and experimental protocols should be conducted to enhance evidence about psychedelic substances.

RESUMEN

Psychedelics are a group of psychoactive substances which produce complex and subjective changes to consciousness and carry unique safety considerations. There is a growing body of work investigating the use of psychedelics for mental health treatment alongside increasing socio-cultural and political acceptance. This rapid evolution has prompted corporations to fund psychedelic clinical trials, leading to a potential rise in conflicts of interest in relevant studies and publications. However, the body of evidence for the safety and efficacy of psychedelic-assisted psychotherapy for psychiatric illnesses is early. There is concern regarding the introduction of bias in psychedelic clinical trials and the selective reporting of results amidst and beyond corporate involvement. At a crucial time in psychedelic drug reform, this paper explores the safety concerns associated with psychedelics, the potential influences of financial stakeholders on safety outcome reporting and the importance of balanced science communication in maintaining public health and safety.

RESUMEN

Major depression disorder is an entity with high prevalence and worldwide impact. Current treatments present a non-response rate of 15-30%, and certain adverse effects are seen like apathy syndrome and lack of emotional response. It is stated that the treatment with psilocybin fungi allows the possibility of dose reduction and suspension of classic psychotropic drugs and entails changes on an emotional and behavioral level that result benefic in patients with major depressive syndrome. We present a case of a 19 years old patient with major depressive syndrome diagnosis. Accompaniment and patient advice was made appealing to the right of autonomy, on the psilocybin microdose self-administration process, aiming to reducing health risks and potentiate probable beneficial effects, with weekly evaluations, for a period of 7 months; using clinical anamnesis, laboratory tests and the Hamilton depression scale. As a result of this intervention, a symptomatic complete remission was proven, alongside with the suspension of conventional pharmacological treatment without discontinuation symptoms and improvements at the communicational level, social interaction and general well-being. These findings support the idea that psilocybin microdose treatments are promising tools in depression treatments. Scientific studies are needed in order to certify these findings.

La depresión mayor es una enfermedad de gran prevalencia e impacto mundial. Los tratamientos actuales presentan una tasa de no respuesta del 15 al 30 %, mientras que en casos de eficacia se suelen observar efectos adversos como el síndrome de apatía y la falta de respuesta emocional. Se postula que el tratamiento con hongos psilocibios genera la posibilidad de reducción de dosis y suspensión de psicofármacos clásicos y ocasiona cambios a nivel emocional y comportamental benéficos en pacientes con trastorno depresivo mayor. Este es un caso de un paciente no binario de 19 años de edad con diagnóstico de trastorno depresivo mayor. Se realizó unacompañamiento y asesoramiento del paciente apelando al derecho de autonomía, en el proceso de autoadministración de microdosis de psilocibina, para disminución de riesgos en salud y potenciar efectos benéficos probables, con evaluación semanal, durante un periodo de 7 meses; utilizando la anamnesis clínica, análisis de laboratorio y la escala validada de depresión de Hamilton. Como resultado de esta intervención se evidenció una remisión completa sintomática, la suspensión del tratamiento farmacológico convencional, sin síntomas de discontinuación y mejorías a nivel comunicacional, de interacción social y bienestar general. Estos hallazgos apoyan la idea de que los tratamientos con microdosis de psilocibina son una herramienta prometedora en los tratamientos de depresión. Se necesitan más estudios que aporten evidencia científica para comprobar dichos hallazgos.

RESUMEN

Lysergic acid diethylamide (LSD) is a synthetic psychedelic compound with potential therapeutic value for psychiatric disorders. This study aims to establish Caenorhabditis elegans as an in vivo model for examining LSD's effects on locomotor behavior. Our results demonstrate that LSD is absorbed by C. elegans and that the acute treatment reduces animal speed, similar to the role of endogenous serotonin. This response is mediated in part by the serotonergic receptors SER-1 and SER-4. Our findings highlight the potential of this nematode as a new experimental model in psychedelic research.

RESUMEN

5-methoxy-N,N-dimethyltryptamine (5-MeO-DMT) is a potent classical psychedelic known to induce changes in locomotion, behaviour, and sleep in rodents. However, there is limited knowledge regarding its acute neurophysiological effects. Local field potentials (LFPs) are commonly used as a proxy for neural activity, but previous studies investigating psychedelics have been hindered by confounding effects of behavioural changes and anaesthesia, which alter these signals. To address this gap, we investigated acute LFP changes in the hippocampus (HP) and medial prefrontal cortex (mPFC) of freely behaving rats, following 5-MeO-DMT administration. 5-MeO-DMT led to an increase of delta power and a decrease of theta power in the HP LFPs, which could not be accounted for by changes in locomotion. Furthermore, we observed a dose-dependent reduction in slow (20-50 Hz) and mid (50-100 Hz) gamma power, as well as in theta phase modulation, even after controlling for the effects of speed and theta power. State map analysis of the spectral profile of waking behaviour induced by 5-MeO-DMT revealed similarities to electrophysiological states observed during slow-wave sleep (SWS) and rapid-eye-movement (REM) sleep. Our findings suggest that the psychoactive effects of classical psychedelics are associated with the integration of waking behaviours with sleep-like spectral patterns in LFPs.

RESUMEN

Ibogaine is a potent atypical psychedelic that has gained considerable attention due to its antiaddictive and antidepressant properties in preclinical and clinical studies. Previous research from our group showed that ibogaine suppresses sleep and produces an altered wakefulness state, which resembles natural REM sleep. However, after systemic administration, ibogaine is rapidly metabolized to noribogaine, which also shows antiaddictive effects but with a distinct pharmacological profile, making this drug a promising therapeutic candidate. Therefore, we still ignore whether the sleep/wake alterations depend on ibogaine or its principal metabolite noribogaine. To answer this question, we conducted polysomnographic recordings in rats following the administration of pure noribogaine. Our results show that noribogaine promotes wakefulness while reducing slow-wave sleep and blocking REM sleep, similar to our previous results reported for ibogaine administration. Thus, we shed new evidence on the mechanisms by which iboga alkaloids work in the brain.

RESUMEN

Psychedelic fungi have experienced a surge in interest in recent years. Most notably, the fungal secondary metabolite psilocybin has shown tremendous promise in the treatment of various psychiatric disorders. The mushroom species that produce this molecule are poorly understood. Here we sought to examine for the first time, the response of a psilocybin-producing species Psilocybe cubensis to casing (peat moss and vermiculite) and supplementation with gypsum (calcium sulfate dihydrate), two common practices in commercial mushroom cultivation. Mycelial samples of genetically authenticated P. cubensis were used to inoculate popcorn grain bags. The fully colonized bags of popcorn grain (0.15 kg) were transferred to bins of 0.85 kg pasteurized horse manure, with or without 1 cm thick layer of casing and/or 5 % gypsum. Our results indicate that the use of a casing layer significantly increases the biological efficiency (161.5 %), by approximately four fold, in comparison to control (40.5 %), albeit with a slight delay (∼2 days) for obtaining fruiting bodies and a somewhat reduced total tryptamine content (0.85 %) as gauged by High Performance Liquid Chromatography measurements. Supplementation with both casing and gypsum, however, appears to promote maximal yields (896.6 g/kg of dried substrate), with a biological efficiency of 89.6 %, while also maintaining high total tryptamine expressions (0.95 %). These findings, revealing methods for maximizing yield of harvest and expressions of psychoactive tryptamines, may prove useful for both home growers and commercial cultivators of this species, and ultimately support the growth of a robust industry with high quality natural products.

RESUMEN

BACKGROUND AND PURPOSE: Ayahuasca (AYA) is a botanical psychedelic with promising results in observational and small clinical trials for depression, trauma and drug use disorders. Its psychoactive effects primarily stem from N,N-dimethyltryptamine (DMT). However, there is a lack of research on how and where AYA acts in the brain. This study addressed these questions by examining the extinction of aversive memories in AYA-treated rats. EXPERIMENTAL APPROACH: We focused on the 5-HT1A and 5-HT2A receptors, as DMT exhibits a high affinity for both of them, along with the infralimbic cortex in which activity and plasticity play crucial roles in regulating the mnemonic process under analysis. KEY RESULTS: A single oral treatment with AYA containing 0.3 mg·kg-1 of DMT increased the within-session extinction of contextual freezing behaviour without affecting its recall. This protocol, when repeated twice on consecutive days, enhanced extinction recall. These effects were consistent for both 1- and 21-day-old memories in males and females. AYA effects on fear extinction were independent of changes in anxiety and general exploratory activity: AYA- and vehicle-treated animals showed no differences when tested in the elevated plus-maze. The 5-HT2A receptor antagonist MDL-11,939 and the 5-HT1A receptor antagonist WAY-100635 infused into the infralimbic cortex respectively blocked within- and between-session fear extinction effects resulting from repeated oral administration of AYA. CONCLUSION AND IMPLICATIONS: Our findings highlight complementary mechanisms by which AYA facilitates the behavioural suppression of aversive memories in the rat infralimbic cortex. These results suggest potential beneficial effects of AYA or DMT in stress-related disorders.

RESUMEN

This essay, situated in the field of bioethics, examines the prohibition of psychedelic use, exploring arguments surrounding the growing evidence of their therapeutic potential and their millennia-long history of cultural and spiritual uses. It initially discusses the historical context of psychedelics and the various terms used to describe them. The essay problematizes the definition of "drugs," highlighting the lack of objective criteria for distinguishing between legal and illicit substances. Drawing on concepts and theoretical frameworks of critical bioethics, it analyzes how the prohibitionist moral discourse is sustained more by political and economic interests than by scientific justifications, leading to stigmatization and vulnerability. The essay advocates for the end of the prohibition of psychedelics based on ethical arguments, emphasizing their importance in reducing individual and collective suffering. The work contributes to a deeper reflection on this socially controversial topic, integrating interdisciplinary knowledge.

RESUMEN

Noribogaine (noribo) is the primary metabolite from ibogaine, an atypical psychedelic alkaloid isolated from the root bark of the African shrub Tabernanthe iboga. The main objective of this study was to test the hypothesis that molecular, electrophysiological, and behavioral responses of noribo are mediated by the 5-HT2A receptor (5-HT2AR) in mice. In that regard, we used male and female, 5-HT2AR knockout (KO) and wild type (WT) mice injected with a single noribo dose (10 or 40 mg/kg; i.p.). After 30 min., locomotor activity was recorded followed by mRNA measurements by qPCR (immediate early genes; IEG, glutamate receptors, and 5-HT2AR levels) and electrophysiology recordings of layer V pyramidal neurons from the medial prefrontal cortex. Noribo 40 decreased locomotion in male, but not female WT. Sex and genotype differences were observed for IEG and glutamate receptor expression. Expression of 5-HT2AR mRNA increased in the mPFC of WT mice following Noribo 10 (males) or Noribo 40 (females). Patch-clamp recordings showed that Noribo 40 reduced the NMDA-mediated postsynaptic current density in mPFC pyramidal neurons only in male WT mice, but no effects were found for either KO males or females. Our results highlight that noribo produces sexually dimorphic effects while the genetic removal of 5HT2AR blunted noribo-mediated responses to NMDA synaptic transmission.

RESUMEN

Psychedelics are being increasingly examined for their therapeutic potential in mood disorders. While the acute effects of ayahuasca, psilocybin, and lysergic acid diethylamide (LSD) last over several hours, inhaled N,N-Dimethyltryptamine (DMT) effects last around 10 min, which might provide a cost- and time-effective alternative to the clinical application of oral psychedelics. We aimed at investigating the safety and tolerability of inhaled DMT (BMND01 candidate). We recruited 27 healthy volunteers to receive a first, lower dose and a second, higher dose (5/20 mg, 7.5/30 mg, 10/40 mg, 12.5/50 mg, or 15/60 mg) of inhaled DMT in an open-label, single-ascending, fixed-order, dose-response study design. We investigated subjective experiences (intensity, valence, and phenomenology), physiological effects (blood pressure, heart rate, respiratory rate, blood oxygen saturation, body temperature), biochemical markers (liver, kidney, and metabolic functions), and adverse events during the acute and post-acute effects of DMT. DMT dose-dependently increased intensity, valence and perceptual ratings. There was a mild, transient, and self-limited increase in blood pressure and heart rate. There were no changes in safety blood biomarkers and no serious adverse events. DMT dose-dependently enhanced subjective experiences and positive valence. Inhaled DMT might be an efficient, non-invasive, safe route of administration, which might simplify the clinical use of this substance. This is the first clinical trial to test the effects of inhaled DMT (BMND01 candidate).

RESUMEN

Abstract Objective Existing scales that seek to measure alterations in self-experience were developed based on studies conducted in developed countries. Therefore, the aim of this study was to evaluate the psychometric properties of the Ego Dissolution Inventory (EDI) after translating and adapting it for the Brazilian context. Methods The measure was translated by two translators fluent in both English and Portuguese, followed by back-translation into English to ensure there was no loss of meaning. The scale was used in an online survey exploring substance use. A total of 528 participants answered the full scale. We calculated the Kaiser-Meyer-Olkin (KMO) measure to evaluate sampling adequacy, then ran exploratory factor analysis (EFAs) to investigate the factor structure of the EDI. Results The scale showed acceptable psychometric properties, with excellent internal consistency and sampling adequacy for factor analysis. Kaiser-Guttman's criteria and Hull's method indicated a three-factor solution, while parallel analysis suggested a two-factor solution. All items showed salient loadings, with two items exhibiting cross-loading. Positive but weak correlations were found between EDI factors 1 and 2 and nature relatedness. Conclusions The validated scale showed solid psychometric properties, with potential differences in factor structure in relation to the English version. Considering validation is an ongoing process, it is recommended that studies be conducted comparing ego dissolution scores across distinct substances and different regions of the country.

RESUMEN

Ibogaine is a natural psychoactive drug that has been investigated for its potential role in the treatment of substance use disorders since the mid-1960s. To evaluate the interest in ibogaine's use as a therapeutic agent, we performed a scientometric analysis covering the last three decades (1993-2002, 2003-2012, and 2013-2022). A complementary analysis was performed to select and describe published clinical trials and meta-analyses. A total of 1523 references were found. Linear growth of publications in the first and third decades were identified, and the average number of publications from 1993 to 2002 was lower than that in the other two decades. Researchers from five continents were identified. Globally, academic research centers in the United States and Canada were the most productive. Cocaine, tobacco, morphine, and alcohol prevailed as major keywords in the first two decades and opioids and psychedelics were included in the third decade. A few key authors were the most co-referenced. One preclinical meta-analysis and no meta-analysis in humans were found. Research trends for ibogaine are widespread, growing, and consonant with current attentiveness in drug abuse. Our findings support the pressing need for rigorous clinical research on ibogaine to evaluate its efficacy and safety.

RESUMEN

This study evaluated the psychometric properties of the Spiritual Well-Being Scale (SWBS) in a Brazilian sample. We analyzed spiritual well-being, defined as existential well-being (EWB) and religious well-being (RWB), among individuals with varying religious and spiritual experiences, both users and non-users of psychedelics. The online cross-sectional survey was conducted in Brazil, from April to June 2022. The psychometric analyses demonstrated reliability and validity based on the internal structure and the relationship with satisfactory external variables concerning the RWB and EWB factors of the SWBS. Validity evidence was shown for both factors (RWB, EWB) with adequate reliability ratings. However, the RWB factor, which was entirely replicated, demonstrated the best group differentiation and internal consistency. Although both factors showed validity, the RWB factor exhibited superior psychometric indices for validity, group discrimination, and reliability. Regarding psychedelics, the association with RWB and EWB demonstrates a U-shaped pattern, as participants who never use these substances typically exhibit higher RWB and EWB indices, succeeded by frequent users. This finding underscores the need for additional studies to further explore the intricate interplay between psychedelics and spiritual well-being.

RESUMEN

The efficacy of psilocybin and other psychedelics as modes of treatment have been demonstrated through clinical trials and other studies in the management of a number of mental illnesses, including some treatment resistant cases. In Psychedelic Assisted Psychotherapy (PAP), psychedelics catalyze or enhance the experience fostered by psychotherapeutic methods. Psychohistoriographic Brief Psychotherapy, conceptualized by the late Professor Frederick Hickling in the 1970's in Kingston, Jamaica, offers a pathway for exploration in the Jamaican context. Applied to individuals, Psychohistoriographic Brief Therapy (PBT) has already shown success in patients with personality disorders in Jamaica through a process which includes documenting life experiences in a psychohistoriogram. In the De La Haye psilocybin Treatment Protocol (DPTP), micro-doses of crushed, dried psilocybin mushrooms are taken throughout an 8-week outpatient process of documenting the components of the psychohistoriogram, making use of the increased openness and empathy associated with the use of psychedelic agents. These sessions are followed by supervised in-office therapeutic/mystical doses of crushed, dried psilocybin mushrooms in the 9th week. Given the legal status and availability of psilocybin containing products in a few countries like Jamaica, there is a potential role for a regulated psychedelic industry contributing to the body of useful and rigorous clinical research which is needed in this area. Clients could benefit as we venture into this new frontier in psychiatry.

RESUMEN

Ring-substituted phenethylamines are believed to induce psychedelic effects primarily by interacting with 5-hydroxytryptamine 2 (5-HT2A) receptors in the brain. We assessed the effect of the psychedelic substances 25H-NBOMe and 25H-NBOH on the depressive-like behavior of male adult rats. Naive Wistar rats were divided into groups to assess the effects of different doses (0.1 mg/kg, 1 mg/kg, and 3 mg/kg) of 25H-NBOMe and 25H-NBOH. The substances were administered intraperitoneally and the hallucinogenic properties were evaluated using the head twitch response test (HTR). Additionally, we assessed their locomotor activity in the open field test (OFT) and depressive-like behavior in the forced swimming test (FST). Our data demonstrated that all doses of synthetic psychedelic substances evaluated exhibited hallucinogenic effects. Interestingly, we observed that both 25H-NBOMe and 25H-NBOH produced a significantly greater motivation to escape in the FST, compared to the control group. Furthermore, we found no significant differences in locomotor activity during the OFT, except for the dose of 3 mg/kg, which induced a reduction in locomotion. This study provides new insights into a potential psychedelic substance, specifically by demonstrating the previously unknown antidepressant properties of a single dose of both 25H-NBOMe and 25H-NBOH. These findings contribute to the ongoing progress of experimental psychiatry toward developing safe and effective clinical practices in the field of psychedelics research.
