BackgroundPsilocybin-induced mystical-type experiences are associated with lasting positive psychological outcomes. Recent studies indicate that trait mindfulness is increased 3 months after psilocybin intake, preceded by decreases in neocortical serotonin 2A receptor (5-HT2AR) binding. However, the association between psilocybin-induced mystical-type experi...
This phenomenological research explored the fast-growing societal trend in psilocybin microdosing, whereby a sub-perceptual amount of the psychedelic is consumed regularly. Anecdotal reports of microdosing have suggested that individuals can experience the relief of depressive symptoms, greater creativity and focus, deeper connections, and improvements in se...
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 and Nutt’s (2017) model of extra-pharmacological (EP) factors. It examined whether such factors should be considered in any psychological suitability test for medicinally prescribed psilocy...
Psilocybin-assisted psychotherapy, i.e., psilocybin treatment with psychological support, has demonstrated the efficacy of psilocybin to reduce depressive symptoms. However, in clinical trials, the structure of psilocybin-assisted psychotherapy is primarily based on preparation, navigation (support during dosing sessions), and integration. For psychotherapeu...
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...
Our hominin ancestors inevitably encountered and likely ingested psychedelic mushrooms throughout their evolutionary history. This assertion is supported by current understanding of: early hominins' paleodiet and paleoecology; primate phylogeny of mycophagical and self-medicative behaviors; and the biogeography of psilocybin-containing fungi. These lines of ...
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...
The primary objective of this qualitative study was to explore the therapeutic trajectories of individuals undergoing psilocybin-assisted group therapy. This interpretive phenomenological analysis focused on an enriched study sample of gay-identified cisgender men ( n = 9) with human immunodeficiency virus diagnosed before 1996 and clinically significant tra...
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 ...
Spontaneous Spiritual Awakenings (SSAs) are subjective experiences characterised by a sud- den sense of direct contact, union or merging with a perceived ultimate reality, the universe, or the divine. These profound transformative experiences have scarcely been researched, de- spite extensive anecdotal evidence suggesting their potential to catalyse drastic,...
Objective: Recent clinical trials have demonstrated that psilocybin may have strong antidepressant effects, and may be effective in the treatment of depressive disorders when embedded in a psychotherapeutic protocol (psilocybin-assisted psychotherapy; PAP). However, despite promising results, the mechanism(s) that may be responsible for the antidepressant ef...
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. This research primarily investigates the potential of psychedelics in the treatment of mental health disorders, their sh...
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...

Despite the fact that psychedelics were proscribed from medical research half a century ago, recent, early-phase trials on psychedelics have suggested that they bring novel benefits to patients in the treatment of several mental and substance use disorders. When beneficial, the psychedelic experience is characterized by features unlike those of other psychia...
5-MeO-DMT is a psychoactive substance found in high concentrations in the bufotoxin of the Colorado River Toad (Bufo alvarius). Emerging evidence suggests that vaporized 5-MeO-DMT may occasion mystical experiences of comparable intensity to those occasioned by more widely studied psychedelics such as psilocybin, but no empirical study has tested this hypothe...
Background: Evidence suggests that classical psychedelics can promote enduring changes in personality, attitudes and optimism, as well as improvements in mental health outcomes. Aim: To investigate the effects of a composite intervention, involving psilocybin, on pessimism biases in patients with treatment-resistant depression (TRD). Methods: Patients with T...
