This article provides a phenomenological account of the role of existential feelings in the acute and lasting effects of psychedelic therapy and attempts to elucidate phenomenologically why certain psychedelic experiences in specific contexts have the potential of providing long-term relief from mental suffering. First, we explain Matthew Ratcliffe’s theory of existential feelings and use it to highlight shared phenomenological characteristics between various mental disorders. Next, we discuss the phenomenology of oceanic feelings to specify the kind of existential feeling that is involved in acute psychedelic experiences and connect this to the existential reorientation that may occur after the use of psychedelics. Following this, we show how this framework of existential feelings allows us to (1) characterize the phenomenological process that takes during therapeutic use of psychedelics, and (2) describe various conditions required for a successful therapeutic psychedelic experience.

AbstractBackgroundMethodsResultsConclusionsCurrently, there are great hopes for psychedelic substances in treating psychiatric conditions and improving well-being. These substances are illegal in many countries, and we lack knowledge of how conflicting discourses shape psychedelic use in naturalistic settings. This study explores how psilocybin use is made meaningful by participants and staff at a retreat including psychedelic ceremonies aimed at personal growth.Ethnographic fieldwork was conducted at a psychedelic retreat with participants from Sweden. The material was organized using Zinberg’s model of drug, set, and setting. Theoretical work related to comparisons was utilized to elucidate how psilocybin use was distinguished from other illicit drug use.The participants’ desires to be fundamentally transformed, combined with the staff’s staging of the setting as a haven primed the participants to approach psilocybin as an inherently benevolent substance. Positive experiences during the ceremonies were attributed to the substance, and negative experiences to personal shortcomings.The staff and participants combined different discourses to define the meaning of psilocybin, all of which condemned using it for purely recreational purposes. The psilocybin use at the retreat was considered an improvement and wholly unrelated to illegal drug use, dissociating this practice from such use to establish legitimate transgression.

AbstractThe renewed interest in psychedelics as treatments for mental health disorders is often referred to as the “Psychedelic Renaissance.” This article assesses whether this resurgence truly constitutes a paradigm shift in psychiatry, as some proponents claim, or if it should be viewed as an integration of existing therapeutic approaches. We explore historical contexts, noting that psychedelics were extensively researched in the mid-20th century and argue that many of the current claims about their novelty overlook prior knowledge and research from that period. While psychedelics do introduce novel aspects, such as rapid therapeutic effects and unique modes of action, we challenge the idea of a full paradigm shift, suggesting that these developments are better understood as enhancements to existing frameworks rather than a wholesale replacement. We emphasize the importance of integrating psychedelics within a broader bio-psycho-social model of psychiatry, combining pharmacological, psychological, and contextual factors. The therapeutic potential of psychedelics in psychotherapy has previously been described as working as “nonspecific amplifiers” of psychological processes, rather than introducing entirely new mechanisms. We suggest a balanced, integrative approach that incorporates psychedelics into existing mental health care models, cautioning against “psychedelic exceptionalism” and the risk of overselling their potential as a revolutionary treatment.

People with cancer experience higher rates of psychological dysfunction than the general population, with extreme inequity among indigenous people. Psychedelic-assisted therapy (PAT) is a reemerging area with promising evidence as a treatment for mental health difficulties. The current study aimed to investigate the perceptions of PAT in indigenous (Māori) and non-indigenous cancer patients in Aotearoa, New Zealand. Eighty-five cancer patients (Māori n = 32, non-Māori n = 53) completed a brief anonymous survey assessing demographics, psychological factors, and awareness and perceptions of PAT. Participants were recruited online (via social media and cancer support e-mail lists) and in person at Auckland City Hospital. Maori had significantly poorer psychological well-being than non-Māori. All participants had low awareness of this novel treatment and held largely neutral attitudes. Regression analyses revealed that predictors of more favorable attitudes toward PAT included greater awareness of psychedelics, advanced cancer stage, younger age, poorer holistic well-being, greater demoralization, and prioritizing treatment effectiveness over possible risks and uncertainty. The current study provides a foundational step in exploring perceptions toward PAT in indigenous and non-indigenous groups. These results have the potential to shape future research trials investigating PAT and further highlight the importance of indigenous involvement in the psychedelic research space.

Novel and traditional psychedelic medicines are attracting interest as potential treatments of mental illness. Before psychedelic therapies can be made available in culturally safe and effective ways to diverse peoples, the field must grapple with the complex legacies of colonialism and ongoing clashes between biomedical and Indigenous Ways of Knowing. This article presents results of a pilot program offering group-based therapy augmented by three sessions of ketamine at a psychedelic dose, for a group of Indigenous participants. This unique project was undertaken in partnership between Roots to Thrive and the Snuneymuxw First Nation to assess this approach's effectiveness and safety for Indigenous peoples. Thematic analysis of qualitative interviews and anonymous feedback received throughout the program from eight participants and two Elders provided rich information on participant motivations, perceived barriers, appreciated and beneficial aspects of the program, and the psychedelic experiences, as well as important directions for further improvement. In addition to challenges, participants attributed significant benefits to the program while highlighting the importance of the involvement of Indigenous team members, the incorporation of traditional approaches to healing, and the cultivation of open and authentic relationships between group participants and facilitators. We discuss important lessons learned and the essential work of reconciliation in, and beyond, psychedelic therapies. [ABSTRACT FROM AUTHOR]

The pharmacological treatment of depression consists of taking antidepressant drugs for prolonged periods; its modest therapeutic effect can often be associated with significant adverse effects, while its discontinuation can lead to relapses. Psilocybin is today a novel and breakthrough therapy for major depression. It is a natural alkaloid in Psilocybe mushrooms, which are endemic to Mexico. Research on a larger scale is lacking in various populations, including the Mexican people. This proposal contemplates the experimental design of a preclinical (toxicity and pharmacological evaluation of an extract in mice) and clinical study by including the chemical analysis of a species of Psilocybe cubensis mushroom to characterize its main constituents. The clinical study will consider the safety evaluation by exploring tolerated doses of Psilocybe cubensis by measuring pharmacokinetic parameters after oral administration in healthy adults and an open trial on a sample of patients with major depressive disorder to assess the safety and efficacy of fully characterized Psilocybe cubensis in a two-single doses treatment, (with assisted psychotherapy), compared with the traditional care model at the Instituto Nacional de Psiquiatría Ramón de la Fuente Muñiz in Mexico City. This report presents the design of a research project with preclinical and clinical experimental components. [ABSTRACT FROM AUTHOR]

Given the mortality, chronicity, and treatment drop-out rates observed among individuals with eating disorders (EDs), innovative approaches are needed. Ayahuasca, a psychedelic plant medicine from the Amazon, is currently being investigated. This study expands on prior exploratory research by describing the perspectives of ayahuasca ceremony leaders regarding their conceptualizations of EDs and the potential therapeutic mechanisms of action of ayahuasca for individuals with EDs. Qualitative content analysis of interviews with 15 ayahuasca ceremony leaders produced two main categories, with relevant subcategories. The first category encompassed the leaders' theories of EDs from a shamanic perspective, including that EDs are symptomatic of an underlying concern, serve a function and affect health in multiple domains. The second category described leaders' perspectives on the potential mechanisms of action of ayahuasca for EDs, including that ayahuasca facilitates "energetic healing"; helps identify, process, and integrate the "root" of the ED; promotes holistic healing; and enhances and/or reorganizes relationships. From the perspectives of ceremony leaders and consistent with previous exploratory research, ceremonial ayahuasca use may offer a potentially useful, novel and complementary intervention for EDs.

Humans have used serotonergic hallucinogens (i.e. psychedelics) for spiritual, ceremonial, and recreational purposes for thousands of years, but their administration as part of a structured therapeutic intervention is still a relatively novel practice within Western medical and psychological frameworks. In the mid-20th century, considerable advances were made in developing therapeutic approaches integrating administration of low (psycholytic) and high (psychedelic) doses of serotonergic hallucinogens for treatment of a variety of conditions, often incorporating psychoanalytic concepts prevalent at that time. This work contributed seminal insights regarding how these substances may be employed with efficacy and safety in targeted therapeutic interventions, including the importance of optimizing set (frame of mind) and setting (therapeutic environment). More recently, clinical and pharmacological research has revisited the effects and therapeutic potential of psychedelics utilizing a variety of approaches. The current article provides an overview of past and present models of psychedelic therapy, and discusses important considerations for future interventions incorporating the use of psychedelics in research and clinical practice.

Eating disorders (EDs) are serious health conditions that are among the most difficult to treat. Innovative treatments are needed and modalities from across cultures must be considered. Ayahuasca is a psychoactive plant-based tea originally used by Amazonian indigenous groups. A growing body of research points to its promise in the healing of various mental health issues. This study explored the potential therapeutic value of ayahuasca in the context of EDs, including the perceived impact of the preparatory diet and the ayahuasca purge. Sixteen individuals previously diagnosed with an ED participated in a semi-structured interview relating to their experiences with ceremonial ayahuasca drinking. Interviews were analyzed using thematic analysis. Themes presented relate to the reduction or cessation of ED and mental health symptoms, shifts in body perception, and the importance of a ceremonial setting and after-care. For some, the preparatory diet resulted in familiar patterns of concern; however, none felt triggered by the purge in ayahuasca. Ceremonial ayahuasca drinking shows promise in the healing of EDs and warrants further research. [ABSTRACT FROM PUBLISHER]
