BackgroundThe United States boasts the largest prison population in the world, conferring significant direct and indirect costs (e.g. lost wages for the incarcerated, increased morbidity/mortality, etc.) to society. Recidivism rates are high for the imprisoned and most interventions to reduce criminality are minimally effective. Thus, in addition to the need...
Background Psilocin, the neuroactive metabolite of psilocybin, is a serotonergic psychedelic that induces an acute altered state of consciousness, evokes lasting changes in mood and personality in healthy individuals, and has potential as an antidepressant treatment. Examining the acute effects of psilocin on resting-state dynamic functional connectivity imp...
Background: Due to increasing evidence of efficacy in treating mental health disorders, psilocybin may become a legal medicinal drug. This study tested the validity of Carhart-Harris & Nutt (2017) model of extra-pharmacological (EP) factors and examined whether such factors should be taken into account in any psychological suitability test for medicinally pr...

Spontaneous Spiritual Awakenings (SSAs) are subjective experiences characterised by a sudden sense of direct contact, union, or complete nondual merging (experience of oneness) with a perceived ultimate reality, the universe, "God," or the divine. These profound transformative experiences have scarcely been researched, despite extensive anecdotal evidence su...
Rationale: Previous studies with the serotonergic hallucinogens LSD and psilocybin showed that these drugs induced changes in personality traits, such as increases in Openness. However, results are inconsistent, and the effects of ayahuasca on personality were never investigated in a controlled trial. Objectives: To assess the effects of ayahuasca on persona...
BackgroundPsilocybin is a psychedelic drug that has shown lasting positive effects on clinical symptoms and self-reported well-being following a single dose. There has been little research into the long-term effects of psilocybin on brain connectivity in humans.AimEvaluate changes in resting-state functional connectivity (RSFC) at 1 week and 3 months after o...
Aims Depression is the single largest contributor to global disability. However, effective treatments are currently lacking, resulting in a significant burden of treatment-resistant depression (TRD). Psilocybin, a serotonergic psychedelic, found as the active compound in 'magic mushrooms', has been proposed as a novel therapeutic avenue for TRD. We aimed to ...
Background: One of the main public health strategies adopted at the beginning of the COVID-19 pandemic consisted of implementing strict lockdowns to stop the transmission of the virus. Despite being an effective measure, the confinement and the associated social isolation create a stressful, potentially lengthy situations that has been proven to have several...

After decades of stagnancy, research on psychedelic substances (such as LSD, psilocybin or DMT) has experienced a renaissance over the last 10 years, with various major research programs being conducted across Europe and the United States.

ObjectivesPsychedelics are powerful psychoactive substances. Natural psychedelics have been used for millennia by human civilizations, in particular in Latin America, while synthetic psychedelics were discovered in the 50s, giving rise to a lot of research before they were prohibited. More recently, their therapeutic properties have been studied especially t...
This review illustrates the relevance of shamanism and its evolution under effects of psilocybin as a framework for identifying evolved aspects of psychedelic set and setting. Effects of 5HT2 psychedelics on serotonin, stress adaptation, visual systems and personality illustrate adaptive mechanisms through which psychedelics could have enhanced hominin evolu...

As classic psychedelics are increasingly legalized and reintroduced into the psychotherapeutic frame, a deeper understanding of their effect on personality and overall wellbeing - as well as their clinical contraindications and potential pitfalls - will prove essential. As a result, this study represents a preliminary investigation into the effect of psilocy...
BackgroundScientific interest in the therapeutic effects of classical psychedelics has increased in the past two decades. The psychological effects of these substances outside the period of acute intoxication have not been fully characterized. This study aimed to: (1) quantify the effects of psilocybin, ayahuasca, and lysergic acid diethylamide (LSD) on psyc...
