Healthcare providers face the challenging task of managing patients who suffer from chronic nociplastic pain conditions. Pain is a multidimensional experience, and the current approach to managing people in chronic pain often fails to meet the needs of these patients. Novel ways of treating people who suffer from chronic nociplastic pain with classic psychedelic agents may offer a new lens...

Given the shifting public perception of psilocybin and associated legal changes, the increase in use observed by Keyes and Patrick is not surprising. The conclusion that this is a rising health concern is not justified by the data, particularly as in this sample non-lysergic acid diethylamide hallucinogen use seems to have increased in a white, educated, relatively higher socio-economic status...

Functional magnetic resonance imaging (fMRI) is increasingly used to non-invasively study the acute impact of psychedelics on the human brain. While fMRI is a promising tool for measuring brain function in response to psychedelics, it also has known methodological challenges. We conducted a systematic review of fMRI studies examining acute responses to experimentally administered psychedelics...

Background: Research with the Psychedelic Experience Questionnaire/Scale (PES) focuses on questions relating to mystical experience (Mystical Experience Questionnaire (MEQ)). The psychometric potential of the non-MEQ items of the PES remains largely unexplored. Aims: We investigated whether the PES also yields subscales besides the MEQ30 subscales. Methods: Data from 239 PES measurements (140...

Abstract Psychedelics are powerful psychoactive substances that alter perception and mood processes. Their effectiveness in the treatment of psychiatric diseases was known before their prohibition. An increasing number of recent studies, due to the indisputable resurgence of serotonergic hallucinogens, have shown their efficacy in alleviating depression, anxiety, substance abuse therapies, and...

Este artículo busca dar a conocer las experiencias y los enfoques de trabajo que tienen los facilitadores de estados expandidos de consciencia que acompañan procesos con LSD. Reconociendo que el acompañamiento de este tipo de experiencias es una práctica que viene en aumento y que reduce los riesgos inherentes a las mismas, surgió el deseo de ahondar sobre éstas, brindando una perspectiva desde...

In recent years, there has been considerable enthusiasm among research groups focused on developing novel therapies for treatment-resistant depression, and a wider community that has had experiences using recreational drugs, in more systematic evaluation of the therapeutic value of these compounds (Goodwin et al., 2022; Young, 2023). This has also been associated with advocacy for...

Lysergic acid diethylamide (LSD), a semisynthetic ergoline alkaloid analogue and hallucinogen, is a potent psychoplastogen with promising therapeutic potential. While a variety of synthetic strategies for accessing ergoline alkaloids have emerged, the complexity of the tetracyclic ring system results in distinct challenges in preparing analogues with novel substitution patterns. Methods of...

Globally, an estimated 260 million people suffer from depression [1], and there is a clear need for the development of new, alternative antidepressant therapies. In light of problems with the tolerability and efficacy of available treatments [2], a global trend is emerging for patients to self-treat depression with microdoses of psychedelic drugs such as lysergic acid diethylamide (LSD) and...

This April will be the 80th anniversary of the discovery of LSD by Albert Hofmann. The so-called 'problem child' of his has come a long way to maturity yet many aspects are unknown. Off late there has been a resurgence in psychedelics research as substances like LSD show promise as therapeutics and also reveal insights about our sensory and cognitive processing. We deconstructed the reported...

The non-selective serotonin 2A (5-HT2A) receptor agonist lysergic acid diethylamide (LSD) holds promise as a treatment for some psychiatric disorders. Psychedelic drugs such as LSD have been suggested to have therapeutic actions through their effects on learning. The behavioural effects of LSD in humans, however, remain incompletely understood. Here we examined how LSD affects probabilistic...

Psychedelics are being explored for their potential therapeutic benefits across a wide range of psychiatric diagnoses and may usher in a new age in psychiatric treatment. There is stigma associated with these currently illegal substances, and use varies by race and age. We hypothesized that minoritized racial and ethnic populations, relative to White respondents, would perceive psychedelic use...

Lysergic acid diethylamide (LSD) is a potent classic serotonergic psychedelic, which facilitates a variety of altered states of consciousness. Here we present the first meta-analysis establishing dose-response relationship estimates of the altered states of consciousness induced by LSD. Data extracted from articles identified by a systematic literature review following PRISMA guidelines were...

Mescaline, lysergic acid diethylamide (LSD), and psilocybin are classic serotonergic psychedelics. A valid, direct comparison of the effects of these substances is lacking. The main goal of the present study was to investigate potential pharmacological, physiological and phenomenological differences at psychoactive-equivalent doses of mescaline, LSD, and psilocybin. The present study used a...

Microdosing psychedelic drugs is a widespread social phenomenon with diverse benefits claimed for mood and cognition. Randomized controlled trials have failed to support these claims, but the laboratory-based dosing in trials conducted to date may have limited ecological validity. Healthy male volunteers were randomized into lysergic acid diethylamide (LSD) (n = 40) and placebo (n = 40) groups...

Vitamin D3, omega-3s show no protection against late-life depression Some older adults with subthreshold depression or at high risk for depression might have elevated inflammation or poor vascular and metabolic health, suggesting that supplementation could improve mood in these individuals. An ancillary study to a trial of vitamin D3 and omega-3 fatty acids examined the effects of these...

La microdosificación (o las microdosis) hace referencia al ingerir una dosis muy baja de una sustancia psicodélica, donde no hay efectos de alteraciones cognitivas, afectivas, perceptivas y neurofisiológicas. Recientemente instituciones como la MAPS, la Universidad Johns Hopkins, el Imperial College of London y la FDA, a dicha microdosificación le han designado como «terapia innovadora», ya que...

Anxiety disorders (ADs) represent the sixth leading cause of disability worldwide, resulting in a significant global economic burden. Over 50% of individuals with ADs do not respond to standard therapies, making the identification of more effective anxiolytic drugs an ongoing research priority. In this work, we review the preclinical literature concerning the effects of lysergic acid...

This article reviews the historical protocols for the administration of “classic” psychedelics in France, from the 1920s to the 1960s. Taking a chronological approach, it investigates the way mescaline, LSD, and psilocybin were administered, the subjects involved, the route of administration, the dosage, and the epistemological context of the research. From the 1930s, the Sainte-Anne school...

Hallucinogen-persisting perception disorder (HPPD), also known as acute hallucinogen-induced psychosis or informally known as "flashbacks," is an unusual condition experienced by patients due to the use of different hallucinogenic substances. Hallucinogen-persisting perception disorder causes many symptoms, predominantly persistent visual perception distortion instead of intermittent...
