Abstract
Research on the positive psychological effects of psychedelics has surged since the early 2000s, particularly regarding increased well-being. Studies have demonstrated how psychedelic-occasioned mystical experiences play a key role in their positive effects, which has prompted an interest in the emotion of awe in the psychedelic context due to its similar phenomenology and associated benefits. This study examined 60 individuals following their visitation to at least one ayahuasca retreat in a country where ayahuasca use was legal or retreats are approved to use ayahuasca, hypothesizing that not only high levels of awe but mystical experiences characterized by high levels of awe would be significantly associated with higher well-being. Neither hypothesis was supported: higher levels of mystical experience with lower perceived vastness, a facet of awe, was significantly associated with higher well-being, possibly highlighting the synergistic relationship between mystical experiences and perceived vastness on well-being. The study has implications for future research, particularly in terms of understanding how the perceived vastness of a person's psychedelic experience may be modulated to mitigate distress and foster well-being.

Abstract
OBJECTIVE Evidence suggests that psilocybin-assisted therapy (PAT) leads to durable shifts in personality structure. However, such changes have yet to be characterized in disorders of addiction. In this secondary analysis from a randomized controlled trial, the authors examined the effect of PAT on personality dimensions in patients with alcohol use disorder (AUD), hypothesizing that PAT would attenuate personality abnormalities in AUD and that reductions in trait impulsiveness would be associated with lower drinking. METHODS Eighty-four adults with AUD were randomized to two medication sessions of either psilocybin (N=44) or active placebo (diphenhydramine; N=40), received 12 weekly psychotherapy sessions, and completed follow-up for an additional 24 weeks. Changes in personality traits (week 36 vs. baseline) were assessed with the revised NEO Personality Inventory; daily alcohol consumption was quantified using the timeline followback. RESULTS Relative to the placebo group, the psilocybin group showed significant reductions in neuroticism and increases in extraversion and openness. Secondary analyses showed that reductions in neuroticism were driven by decreases in the facets depression, impulsiveness, and vulnerability; increases in openness were driven by increases in the facets openness toward feelings and fantasy. Across all participants, decreases in impulsiveness were associated with lower posttreatment alcohol consumption, and an exploratory analysis revealed that these associations were strongest among psilocybin-treated participants who continued moderate- or high-risk drinking prior to the first medication session. CONCLUSIONS PAT elicited durable shifts in personality, suggesting normalization of abnormal personality trait expression in AUD. Further study is needed to clarify whether PAT exerts its beneficial effects by reducing impulsiveness or whether impulsive individuals inherently respond better to PAT.

Abstract
BACKGROUND Obsessive-compulsive disorder (OCD) is a complex condition marked by persistent distressing thoughts and repetitive behaviours. Despite its prevalence, the mechanisms behind OCD remain elusive, and current treatments are limited. This protocol outlines an investigative study for individuals with OCD, exploring the potential of psilocybin to improve key components of cognition implicated in the disorder. The PsilOCD study strives to assess the effects of low-moderate psilocybin treatment (10 mg) alongside non-interventional therapy on several facets of OCD. The main focus points of PsilOCD are cognitive flexibility, measured with cognitive tests, and neuroplasticity, assessed through electroencephalography (EEG). METHODS 20 blinded participants with OCD will complete two dosing sessions, separated by four weeks, where they will receive 1 mg of psilocybin on the first and 10 mg on the second. The first dose serves as an active placebo, and the latter is a low-moderate dose that induces relatively mild-moderate emotional and perceptual effects. Participants will be supported by trained psychedelic therapists, who will sit with them during each dosing session and provide virtual preparation and integration sessions over the 12-week study period. Therapeutic support will be the same for both the 1 mg and 10 mg sessions. PsilOCD's primary outcomes include scores in the intradimensional-extradimensional (ID-ED) shift task, which is an established measure of cognitive flexibility, and neuroplasticity as quantified by a visual long-term potentiation (vLTP) task. This task is delivered as part of an EEG paradigm and measures acute quantified changes in neuroplasticity in the brain's visual system. The ID-ED task will be conducted twice, two days after each dosing session, and the EEG recordings will also be taken twice, immediately after each session. Secondary outcome assessments will include OCD and affective symptom severity, as well as an array of patient-reported outcome measures (PROMs), in the form of questionnaires designed to assess well-being, dissociable and well-established mood-related (affective) measures, and participants' subjective experience of the psilocybin experience. DISCUSSION This study's results are expected to offer critical insights into the neural mechanisms underlying the effects of psilocybin-assisted therapy in treating OCD, and whether these correlate with changes in the cognitive features of the condition. As a secondary aim, it will ascertain whether a low, tolerable dose is a feasible and efficacious clinical treatment, and will provide crucial data to guide the design of a potential follow-up randomised control trial (RCT).

Abstract
Introduction This perspective on experiential training delves into the potential benefits and counterarguments related to integrating firsthand experience of psychedelic-assisted therapy (PaT) to enhance the competency of trainees. The Case for Experiential Training as a Core PaT Competency Experiential training serves a dual purpose: promoting therapists' mental wellness and refining their skills in facilitating healing in nonordinary states of consciousness. With a rising demand for PaT amid a growing mental health crisis, therapists are increasingly seeking PaT training, including experiential training from underground sources. Educators actively strive to establish formal PaT competencies and training standards, recognizing the need to consider both perspectives in this discourse. Counter Arguments The emergence of differing opinions on the therapeutic value of firsthand exposure to PaT and concerns about potential bias underscores the necessity for further research to substantiate claims on both sides. Access Whether or not consensus is achieved, the persistent demand for experiential training remains. Offering this form of training in regulated settings has the potential to reduce reliance on illicit sources for this sought-after form of training, ensuring a more controlled and ethical approach.

Abstract
The psychedelic psilocybin has shown promise both as treatment for psychiatric conditions and as a means of improving well-being in healthy individuals. In some jurisdictions (e.g., Oregon, USA), psilocybin use for both purposes is or will soon be allowed and yet, public attitudes toward this shift are understudied. We asked a nationally representative sample of 795 US Americans to evaluate the moral status of psilocybin use in an appropriately licensed setting for either treatment of a psychiatric condition or well-being enhancement. Showing strong bipartisan support, participants rated the individual's decision as morally positive in both contexts. These results can inform effective policy-making decisions around supervised psilocybin use, given robust public attitudes as elicited in the context of an innovative regulatory model. We did not explore attitudes to psilocybin use in unsupervised or non-licensed community or social settings.

Abstract
Psychedelic therapy has seen a resurgence of interest in the last decade, with promising clinical outcomes for the treatment of a variety of psychopathologies. In response to this success, several theoretical models have been proposed to account for the positive therapeutic effects of psychedelics. One of the more prominent models is "RElaxed Beliefs Under pSychedelics," which proposes that psychedelics act therapeutically by relaxing the strength of maladaptive high-level beliefs encoded in the brain. The more recent "CANAL" model of psychopathology builds on the explanatory framework of RElaxed Beliefs Under pSychedelics by proposing that canalization (the development of overly rigid belief landscapes) may be a primary factor in psychopathology. Here, we make use of learning theory in deep neural networks to develop a series of refinements to the original CANAL model. Our primary theoretical contribution is to disambiguate two separate optimization landscapes underlying belief representation in the brain and describe the unique pathologies which can arise from the canalization of each. Along each dimension, we identify pathologies of either too much or too little canalization, implying that the construct of canalization does not have a simple linear correlation with the presentation of psychopathology. In this expanded paradigm, we demonstrate the ability to make novel predictions regarding what aspects of psychopathology may be amenable to psychedelic therapy, as well as what forms of psychedelic therapy may ultimately be most beneficial for a given individual.

Abstract
Research over the past several decades suggests that meaningful psychedelic experiences can engender long-term effects on subjective wellbeing. However, less research has investigated the psychological mechanisms through which these effects may emerge. In the present study, participants (N = 201) completed an online survey that retrospectively measured the acute effects of a meaningful psychedelic experience, as well as changes in subjective well-being and death anxiety. Reductions in death anxiety significantly mediated the effects of mystical experience on satisfaction with life, positive affect, and negative affect. Reductions in death anxiety did not mediate any of the effects of psychological insight. Although correlational, the findings are consistent with the hypothesis that some of the benefits of psychedelic-induced mystical experiences on subjective well-being may emerge due to reductions in death anxiety. Nevertheless, further research is needed to establish a causal effect of reduced death anxiety on well-being in the context of psychedelic experiences.

Abstract
BACKGROUND Past research reports a positive relationship between experience with classic serotonergic psychedelics and nature relatedness (NR). However, these studies typically do not distinguish between different psychedelic compounds, which have a unique psychopharmacology and may be used in specific contexts and with different intentions. Likewise, it is not clear whether these findings can be attributed to substance use per se or unrelated variables that differentiate psychedelic users from nonusers. AIMS The present study was designed to determine the relative degree to which lifetime experience with different psychedelic substances is predictive of self-reported NR among psychedelic-experienced users. METHODS We conducted a combined reanalysis of five independent datasets (N = 3817). Using standard and regularized regression analyses, we tested the relationship between degree of experience with various psychedelic substances (binary and continuous) and NR, both within a subsample of psychedelic-experienced participants as well as the complete sample including psychedelic-naïve participants. RESULTS/OUTCOMES Among people experienced with psychedelics, only past use of psilocybin (versus LSD, mescaline, Salvia divinorum, ketamine, and ibogaine) was a reliable predictor of NR and its subdimensions. Weaker, less reliable results were obtained for the pharmacologically similar N,N-dimethyltryptamine (DMT). Results replicate when including psychedelic-naïve participants. In addition, among people exclusively experience with psilocybin, use frequency positively predicted NR. CONCLUSIONS/INTERPRETATION Results suggest that experience with psilocybin is the only reliable (and strongest) predictor of NR. Future research should focus on psilocybin when investigating effects of psychedelic on NR and determine whether pharmacological attributes or differences in user expectations/use settings are responsible for this observation.

Spatiotemporal Mapping of Online Interest in Cannabis and Popular Psychedelics before and during the COVID-19 Pandemic in Poland. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:ijerph19116619.

Abstract
Background: Psychedelics represent a unique subset of psychoactive substances that can induce an aberrant state of consciousness principally via the neuronal 5-HT2A receptor. There is limited knowledge concerning the interest in these chemicals in Poland and how they changed during the pandemic. Nonetheless, these interests can be surveyed indirectly via the web. Objectives: We aim to conduct a spatial-temporal mapping of online information-seeking behavior concerning cannabis and the most popular psychedelics before and during the pandemic. Methods: We retrieved online information search data via Google Trends concerning twenty of the most popular psychedelics from 1 January 2017 to 1 January 2022 in Poland. We conducted Holt–Winters exponential smoothing for time series analysis to infer potential seasonality. We utilized hierarchical clustering analysis based on Ward’s method to find similarities of psychedelics’ interest within Poland’s voivodships before and during the pandemic. Results: Twelve (60%) psychedelics had significant seasonality; we proved that psilocybin and ayahuasca had annual seasonality (p-value = 0.0120 and p = 0.0003, respectively), and four substances—LSD, AL-LAD, DXM, and DOB—exhibited a half-yearly seasonality, while six psychedelics had a quarterly seasonal pattern, including cannabis, dronabinol, ergine, NBOMe, phencyclidine, and salvinorin A. Further, the pandemic influenced a significant positive change in the trends for three substances, including psilocybin, ergine, and DXM. Conclusions: Different seasonal patterns exist for psychedelics, and some might correlate with school breaks or holidays in Poland. The pandemic induced some changes in the temporal and spatial trends. The spatial-temporal trends could be valuable information to health authorities and policymakers responsible for monitoring and preventing addictions.

Abstract
Mystical experiences triggered by psychedelic drugs predict symptom reduction in various psychiatric disorders, and increased well-being in healthy individuals. This work aimed at validating a French version of a tool used to measure mystical experiences: the Revised Mystical Experience Questionnaire-30 items (MEQ30). Construct validity, internal consistencies, concurrent, discriminant, and predictive validities of the French MEQ30 were examined using data about the most significant psychedelic experience of 320 French individuals. Results showed that the original four-factor (i.e., mystical, positive mood, transcendence, and ineffability) structure fit the data best, with good to excellent statistical indices. Total French MEQ30 score was strongly associated with subjective ratings of the mystical (i.e., mystical, spiritual, or religious, and personally significant) and drug intensity-related qualities of the experience, but not with non-mystical (i.e., fun, inebriating, and easy) qualities. Moreover, French MEQ30 score was a significant predictor of subjective positive changes in psychological well-being, relations with self and others, feeling of proximity or connection with nature, and creativity, whereas drug intensity-related and non-mystical qualities of the experience were not, or were only weakly associated with such changes. This French version of the MEQ30 seems to be an appropriate tool for measuring mystical experiences among French speaking individuals.

Abstract
Abstract
Background and aims
Multiple laboratories have proposed measures of subjective effects of psychedelics as potential mediators of their therapeutic impact. Other work has identified individual differences that covary with subjective responses in informative ways. The range of potential measures of responses, traits, and outcomes is vast. Ideas for new measures are likely numerous. The field will progress efficiently if proposed new scales can add incremental validity. Semantic Scale Network analyses identify conceptual overlap among scales based on items (rather than participant ratings), which could help laboratories avoid putting effort into measures that are unlikely to account for unique variance. Semantic Scale Network analyses can also reveal links to constructs from disparate research literatures, potentially helping investigators generate novel hypotheses and explain connections among disparate findings. The results of Semantic Scale Network analyses have the potential to improve as more investigators enter their scales into the corpus.
Method
Example analyses using the revised Mystical Experiences Questionnaire (MEQ) underscore the uniqueness and discriminant validity of the MEQ subscales.
Results
Findings dovetail with published theorizing and suggest potentially novel links with different therapeutic effects. The MEQ total or subscales overlap with measures of awe, inspiration, regret, dissatisfaction, transcendence, depression, fatigue, and spirituality. Links with measures of stress, alexithymia, and gender identity suggest lines of further work.
Conclusions
This analytic approach might suggest unique applications for psychedelic-assisted treatments and provide perspectives on phenomena outside the field. As psychedelic researchers enter their scales to the corpus for Semantic Scale Network analyses, the field will benefit.

Abstract
Abstract
Serotonergic (or “classic”) psychedelics have struck many researchers as raising significant philosophical questions that, until recently, were largely unexplored by academic philosophers. This paper provides an overview of four emerging lines of research at the intersection of academic philosophy and psychedelic science that have gained considerable traction in the last decade: selfless consciousness, psychedelic epistemology, psychedelic ethics, and spiritual/religious naturalism. In this paper, we highlight philosophical questions concerning (i) psychedelics, self-consciousness, and phenomenal consciousness, (ii) the epistemic profile of the psychedelic experience; (iii) ethical concerns about the appropriate use of psychedelics; and (iv) whether spiritual or religious dimensions of psychedelic use are compatible with a naturalistic worldview.

Abstract
Recent media advocacy for the nascent psychedelic medicine industry has emphasized the potential for psychedelics to improve society, pointing to research studies that have linked psychedelics to increased environmental concern and liberal politics. However, research supporting the hypothesis that psychedelics induce a shift in political beliefs must address the many historical and contemporary cases of psychedelic users who remained authoritarian in their views after taking psychedelics or became radicalized after extensive experience with them. We propose that the common anecdotal accounts of psychedelics precipitating radical shifts in political or religious beliefs result from the contextual factors of set and setting, and have no particular directional basis on the axes of conservatism-liberalism or authoritarianism-egalitarianism. Instead, we argue that any experience which challenges a person's fundamental worldview-including a psychedelic experience-can precipitate shifts in any direction of political belief. We suggest that the historical record supports the concept of psychedelics as "politically pluripotent," non-specific amplifiers of the political set and setting. Contrary to recent assertions, we show that conservative, hierarchy-based ideologies are able to assimilate psychedelic experiences of interconnection, as expressed by thought leaders like Jordan Peterson, corporadelic actors, and members of several neo-Nazi organizations.

Abstract
Abstract. After decades of stagnation, research on psychedelic substances (such as lysergic acid diethylamide [LSD], psilocybin, or N,N-dimethyltryptamine [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 short- and long-term effects on recreational users, and the neurological and cognitive processes responsible for their effects. The present review provides a concise summary of the most recent insights gained from this research. We briefly outline the history of psychedelic research, the objective and subjective effects caused by these substances, the prevalence and socio-psychological correlates of their use, as well as their potential for harm. Subsequently, we review empirical research on the beneficial effects of psychedelics in clinical samples, focusing on their efficacy in the treatment of major depression, anxiety, and substance use disorders, and discuss research on the proposed neural and cognitive mechanisms behind these effects. We then review research on their effects on healthy subjects, focusing on psychological well-being as well as changes in personality, nature-relatedness, and creativity. Finally, we review empirical evidence regarding the long-term effects of single experiences with psychedelics and conclude with a summary and outlook.

Abstract
Therapeutic psychedelic administration and contact with nature have been
associated with the same psychological mechanisms: decreased
rumination and negative affect, enhanced psychological connectedness
and mindfulness-related capacities, and heightened states of awe and
transcendent experiences, all processes linked to improvements in
mental health amongst clinical and healthy populations. Nature-based
settings can have inherently psychologically soothing properties which
may complement all stages of psychedelic therapy (mainly preparation
and integration) whilst potentiating increases in nature relatedness,
with associated psychological benefits. Maximising enhancement of
nature relatedness through therapeutic psychedelic administration may
constitute an independent and complementary pathway towards
improvements in mental health that can be elicited by
psychedelics.
