Rationale: Psychedelic research re-emerged from a period of suppression into the so-called psychedelic renaissance. In parallel, most media reporting has shifted from the overstatement of the risks of psychedelics to overly positive hype. As the empirical evidence is more equivocal than frequently portrayed, the conclusions about the effectiveness of psyched...
Abstract Microdosing psychedelics has garnered considerable attention within both nonprofessional circles and the scientific community in recent years. This method involves taking small, non-hallucinogenic doses of substances like LSD or psilocybin over weeks or months, purportedly to enhance specific behaviors, emotions, or address psychiatric conditions. E...
Previous research has proposed that there may be potential synergies between psychedelic and meditation interventions, but there are still knowledge gaps that merit further investigation. Using a longitudinal observational research design with samples representative of the US and UK adult population with regard to sex, age, and ethnicity ( = 9732), we invest...
In this study, for the first time, we explored a dataset of functional magnetic resonance images collected during focused attention and open monitoring meditation before and after a five-day psilocybin-assisted meditation retreat using a recently established approach, based on the Mapper algorithm from topological data analysis. After generating subject-spec...
The transition of HIV into a chronic illness has brought to the forefront the pressing need to address the complex web of social determinants of HIV outcomes. A structured literature search and narrative review of studies describing intervention strategies for mental health among sexual/gender minority (SGM) older adults living with HIV (OALWH) published in ...
Despite common depictions in the media, there is little scientific evidence on microdosing psychedelic drugs. We assessed awareness, prevalence, and dosing practices of microdosing psychedelic drugs among young adults 18-22 years old from Southern California (2018-2019). We examined whether sociodemographic factors, personality traits, mental health, or othe...
There has been increasing scientific and clinical interest in studying psychedelic and meditation-based interventions in recent years, both in the context of improving mental health and as tools for understanding the mind. Several authors suggest neurophysiological and phenomenological parallels and overlaps between psychedelic and meditative states and sugg...
ObjectiveTreatment for anorexia nervosa (AN) remains challenging; there are no approved psychopharmacological interventions and psychotherapeutic strategies have variable efficacy. The investigation of evidence-based treatments has so far been compounded by an underdeveloped understanding into the neurobiological changes associated with the acute stages of A...
The investigators are doing this project to investigate potential neurophysiological synergy effects between mindfulness meditation and psychedelics. Previous studies have found that both mindfulness and psychedelics like psilocybin modulate neural activity and connectivity of the same brain network. However, little is known about the potential interactions ...
Flotation-Reduced Environmental Stimulation Therapy (REST) and mindfulness meditation (MM) are known to induce altered states of consciousness (ASC) and self-consciousness. In this study, we use a phenomenological and predictive processing (PP) framework to compare the interventions alongside the psychedelic experience. Ego-dissolution scores were greater th...

OBJECTIVE: The primary aim of this qualitative study was to delineate psychological mechanisms of change in the first randomized controlled trial of psilocybin-assisted psychotherapy to treat alcohol use disorder (AUD). Theories regarding psychological processes involved in psychedelic therapy remain underdeveloped. METHOD: Participants (N = 13) mostly ident...
BackgroundClassic serotonergic psychedelics have anecdotally been reported to show a characteristic pattern of subacute effects that persist after the acute effects of the substance have subsided. These transient effects, sometimes labeled as the 'psychedelic afterglow', have been suggested to be associated with enhanced effectiveness of psychotherapeutic in...
Previous research has investigated potential synergies between classic psychedelics and meditation practice, but relatively little remains known about the relationship between classic psychedelic experiences and engagement with meditation practice.The purpose of this study was to investigate associations between classic psychedelic experiences and engagement...
Abstract Whether occasioned through careful, consistent meditative practice or through quicker means like the ritual ingestion of psilocybin or ayahuasca, global contemplative practices have established effective systems of implementing, directing, and integrating the very kinds of non-ordinary experiences central to psychedelic use. However, contemplative t...
The detrimental effects of Post-Traumatic Stress Symptoms (PTSS) and Post-Traumatic Stress Disorder (PTSD) and the benefits of Post-Traumatic Growth (PTG) are well established for cancer survivors. Increased cancer survival rates necessitate an understanding of how these two paradoxical outcomes, PTSS/PTSD and PTG, are targeted through interventions. This sy...
There are neurophysiological and phenomenological overlaps between psychedelic and meditative states, but there is little evidence on how exposure to psychedelics might be associated with meditation-related variables. We assessed lifetime classic psychedelic use, ego dissolution during one's most intense experience using a classic psychedelic, and exposure t...
While anecdotal reports claim that psychedelic microdosing reduces anxiety and mood symptoms, evidence supporting these claims is scarce. This cross-sectional study investigated the association between microdosing and trait anxiety. Furthermore, it was investigated if trait mindfulness mediated this association. Participants completed anonymous online questi...
