Classic psychedelic medicines for adolescent refractory mental health disease

Journal of Psychedelic Studies March 26, 2026 Aly Shah Aziz

Adolescent treatment-resistant mental health disorders are increasing worldwide, and standard medications and therapy often fail. Classic psychedelics like psilocybin, LSD-25, and DMT, given within psychedelic-assisted therapy, have shown strong effectiveness in adults with refractory conditions, but adolescents have been excluded from trials. Safety concerns in adolescents are justified but must be weighed against limitations in current evidence, which is observational and underpowered for long-term outcomes. Adult studies indicate low physiological toxicity, minimal dependence risk, and a wide therapeutic index, but these findings cannot be directly applied to developing adolescents. This commentary advocates for cautious, ethically grounded research with these compounds in adolescents who have not responded to other treatments.

The long roots of ibogaine: A journey from plant to pharmaceutical

Journal of Psychedelic Studies March 9, 2026 Genís Ona, Sidsel Marie

Ibogaine, a psychedelic alkaloid, has a history before its 1960s anti-addictive discovery that involves colonial appropriation, early pharmaceutical research, and commodification. During French colonial rule, ibogaine-containing plants from the Congo Basin were classified and appropriated. In 1900, ibogaine was isolated from Tabernanthe iboga, leading to early French scientific research on its effects. Throughout the 20th century, ibogaine was commercialized in several pharmaceutical products, including Dragées Nyrdahl, Grains des Anémiques, Syséros, Viris Lucet, Ibobiose, and Iperton. Evidence shows ibogaine was used in Mexico in 1913 for substance use disorder, challenging the dominant account of its anti-addictive discovery. Indigenous medicinal knowledge from the Congo Basin critically shaped subsequent scientific understanding.

Exploring associations between connectedness and death anxiety following a psychedelic experience

Journal of Psychedelic Studies March 9, 2026 Noah N. Barr, Briony Larance, Matthew J. Schweickle et al.

A survey of 106 adults who had a meaningful psychedelic experience found that increases in feelings of connectedness—to oneself, others, and the world—were linked to reduced fear of death and death avoidance. Participants reported these changes when comparing the three months before and after the experience. Greater connectedness in all three domains was associated with less fear of death, but only connectedness to self and others was tied to lower death avoidance. The intensity of the mystical experience was also related to greater connectedness and less fear of death, but not to death avoidance. The authors call for further research to clarify causality and whether these changes reflect adaptive acceptance or denial.

Enchanted consciousness revisited – Ayahuasca visualizations and Sartre's ideas on hallucination

Journal of Psychedelic Studies March 9, 2026 Lajos Horváth

This paper extends Sartre's concept of enchanted consciousness by integrating insights from psychedelic research. It first examines contradictions in Sartre's mescaline experiment and limits of his phenomenological analysis of hallucination. Then it argues that Benny Shanon's typology of ayahuasca hallucinations, grounded in phenomenological cognitive psychology, reveals aspects of enchanted consciousness Sartre missed. The phenomenon of double bookkeeping from phenomenological psychiatry illustrates delusional world characteristics. Comparing pathological double bookkeeping with psychedelic bookkeeping expands the idea of enchanted consciousness. Finally, Sartre's views on hallucination are updated, defining captivated consciousness through psychedelic double bookkeeping.

Exploring barriers and opportunities for Black, Indigenous, and People of Color (BIPOC) therapists in psychedelic-assisted therapy: A qualitative study

Journal of Psychedelic Studies March 1, 2026

BIPOC therapists see both opportunities and barriers to engaging in psychedelic-assisted therapies (PAT). Opportunities include increasing diversity in the field, fostering safety and trust for clients of color, and providing culturally attuned care for trauma rooted in systemic oppression. Barriers include financial and geographic inaccessibility of training, exclusionary training environments, stigma around psychedelics, and the extractive nature of current Western therapeutic models. Participants recommended culturally responsive training, mentorship, financial support, and community education. Most participants were African American/Black, which may limit transferability. The work highlights the need for intentional efforts to create equitable, culturally informed care.

Ibogaine for the treatment of Parkinson's disease: A case report

Journal of Psychedelic Studies January 6, 2026 Tobias Erny, Elba Yatziri Cano Montenegro, Joern Barth et al.

A 52-year-old woman with Parkinson's disease who was becoming less responsive to standard treatment took daily low doses of ibogaine hydrochloride (up to 75 mg) for 80 days. After treatment, she showed substantial improvements in motor symptoms, quality of life, fatigue, and depression, as measured by validated clinical scales. However, her sleep quality declined, possibly due to ibogaine's stimulant effects. She also reported fewer freezing episodes, better mobility, more energy, and greater optimism. No adverse events occurred. This first case study using validated instruments suggests ibogaine may alleviate Parkinson's symptoms, but larger controlled trials are needed.

Exploring the first use of psychedelic macrodoses in Latin American adults: Sociodemographic profiles, consumption factors, and subjective experiences

Journal of Psychedelic Studies November 20, 2025 Óscar Véliz‐garcía, Marcos Domic‐siede

Among 4,810 Latin American adults from six countries, the most common first psychedelic macrodose was psilocybin mushrooms (57.6%), followed by LSD (33.3%) and MDMA (17.5%). Most used these substances for recreation (70.5%), with spiritual (21.6%) and therapeutic (5.2%) motivations less frequent. Consumption typically occurred in social settings, especially with friends (65.7%), and 9.1% used them alone. Psilocybin was linked to introspection and well-being, ayahuasca to mystical states, and MDMA to heightened empathy. Familiar environments were associated with more positive experiences. Although 86.3% continued use, the main reason for stopping was lack of opportunity, not negative outcomes.

A qualitative study of long-term members of ayahuasca spiritual communities in the United States: Motivations, practices, experiences and beliefs

Journal of Psychedelic Studies November 18, 2025 Joseph T. la Torre, Ariana Kam, Todd Youngs et al.

Long-term participants in ayahuasca spiritual communities in the United States describe these groups as spaces for healing trauma, addiction, and psychological distress, offering belonging and cultural identity. These communities blend Western biomedical views of psychedelics with entheogenic spiritual frameworks, creating a hybrid healing paradigm centered on ritual, music, and shared intention. Members often move from self-focused healing toward relational growth and altruistic action, becoming facilitators and stewards. They navigate interpersonal tensions that foster emotional growth and operate in a legal grey zone, balancing risks of practice and identity. Joining such a community requires careful discernment regarding values, group dynamics, and safety. U.S. ayahuasca communities differ from individualized clinical psychedelic models by emphasizing community, spirituality, and mutual transformation.

Psychedelic preparation and integration through depth hypnosis spiritual counseling

Journal of Psychedelic Studies October 17, 2025 J. Adler, Isa Gucciardi

A transpersonal counseling model called Depth Hypnosis Spiritual Counseling can help psychotherapists and counselors prepare clients for and integrate experiences with psychedelic substances. The model combines earth-based spiritual traditions that originally used psychedelic plants as medicine with practices from Transpersonal Psychology, Buddhist Psychology, hypnotherapy, Applied Shamanism, and Integrated Energy Medicine. Key aspects include setting intentions, managing expectations, attending to set and setting, and addressing regulation. Integration work covers challenges, peak experiences, and adverse experiences. The approach aims to support healing potential and insight gained from psychedelic encounters.

Behavioural investigations of psilocybin in non-human animals 1962–2021: A scoping review

Journal of Psychedelic Studies September 11, 2025 Ron Shore, K. Dobson, Nina Thomson et al.

A scoping review of 77 pre-clinical studies (1962–2021) found that psilocybin has a strong safety profile with no evidence of biological toxicity, even at very high doses. Most studies (64) used rodents, and 51 studies administered psilocybin, 30 psilocin, and 4 whole mushroom extracts. Effects included acute arousal, dose-dependent sedation, reduced fear conditioning at low doses, reduced aggression, improved valence, acute disruption of working memory, rescuing of deficits from chronic stress, and improved learning when combined with repeated environmental exposure after drug effects resolved. Study quality varied: only 43 studies reported housing conditions, and 17 failed to report sample size.

Entity and environment relationships in psychedelic experiences resulting from inhalation of N,N-dimethyltryptamine

Journal of Psychedelic Studies September 8, 2025 Stephen Kagan

Narratives of DMT experiences show consistent patterns linking the types of entities encountered to the environments in which they appear. Analyzing online accounts of experiences from smoking N,N-dimethyltryptamine, the study identified different entity types and charted their frequency across various environments. Some environments had unique mixtures of dominant and less common entity varieties. The findings provide a framework for understanding the progression of these extraordinary experiences and may assist therapeutic, spiritual, and exploratory uses by revealing predictable relationships between the content of psychedelic experiences.

Comparative effects of ayahuasca and breathwork on self-reported cognitive flexibility, emotion regulation, positive affect, and sleep quality

Journal of Psychedelic Studies September 4, 2025 Giordano Novak Rossi, Rishma S. I. Khubsing, Eline Haijen et al.

Both a single ayahuasca ceremony and a single breathwork session led to lasting improvements in cognitive flexibility, emotion regulation, positive affect, and sleep quality over three months. Improvements in cognitive flexibility appeared before changes in emotion regulation, partially supporting the idea that cognitive shifts may drive later emotional gains. The two treatments did not differ in their overall benefits, and the role of participants' experience and motivation remains unclear. The findings suggest that both practices can promote psychological well-being, but further research is needed to clarify the mechanisms and temporal order of these effects.

Factors associated with psychedelic attitudes and usage among college students

Journal of Psychedelic Studies July 4, 2025 W. Hwang, Yuhan Kong, Ken A. Fujimoto et al.

Attitudes toward psychedelics strongly predict actual use among college students, explaining 85.6% of the variance in lifetime use. Male, sexual-minority, older, and non-religious students, as well as those who had used other substances, held more positive attitudes, which in turn made them more likely to have used psychedelics. Lifetime psychedelic use was directly associated with better mental health. A new 12-item Psychedelic Attitudes Scale (PAS) was validated in a sample of 466 liberal arts college students and showed good psychometric properties.

“Diversity makes the richness of humanity”: The emergence and persistence of mental imagery after self-reported psilocybin truffles intake in an autistic woman with “blind imagination” (aphantasia): A 33-month retrospective case report

Journal of Psychedelic Studies June 17, 2025 Kevin Rebecchi

A 34-year-old autistic woman with lifelong aphantasia—the inability to form visual mental images—experienced vivid, manipulable mental imagery for the first time after consuming psilocybin truffles. The effect persisted beyond the drug's acute psychedelic phase. Her score on the Vividness of Visual Imagery Questionnaire rose from a baseline of 16 before intake to 80 afterward; at 12 months it was 59, and at 33 months it increased to 68, slightly above the population average. The case aligns with prior work on psilocybin's effects on brain connectivity and neuroplasticity. It suggests psilocybin may modulate mental imagery in congenital aphantasia and encourages viewing aphantasia as cognitive diversity rather than a disorder.

Turning online to tune in: Psychedelic information seeking in an era of renewed psychedelic curiosity

Journal of Psychedelic Studies May 16, 2025 Oskar Enghoff, Margit Anne Petersen, Søren Holm et al.

People who have used psychedelics, whether therapeutically or non-therapeutically, and those who have never used them all strongly prefer online sources for information about psychedelics. Different groups show distinct patterns in where they get information and what types of content they access, indicating varied online social learning environments for consumption practices. Online content influences both current and potential future use, even as public attention increasingly focuses on psychedelic therapy. Public health institutions could use these online channels to engage with the psychedelic resurgence.

Cornutopia: A short story and what it can tell us about ethnic minority views on psychedelic research, and the potential impact on clinical outcomes

Journal of Psychedelic Studies May 13, 2025 Caroline Hayes

A fictional story, Cornutopia, by British-Nigerian author Irenosen Okojie, offers a critical outsider's perspective on the enthusiasm surrounding psychedelic research. The protagonist, a young Black woman, participates in a psychedelic clinical trial and has a negative experience, leaving her in worse condition than before. The narrative highlights issues of bias, patient vulnerability, and mistrust of healthcare professionals, which is significant given calls for greater diversity in trials and the potential role of race in set and setting. Based on themes in the story, recommendations are made to improve researchers' awareness of barriers to inclusion for ethnic minorities and to address possible racial differences in therapy outcomes.

Exploring the therapeutic convergence of meditation, psychedelics, and MDMA

Journal of Psychedelic Studies April 17, 2025 Jacob T. Dines

Psychedelic and MDMA-assisted psychotherapy are emerging as new treatment models for mental illnesses like PTSD and depression, as well as for improving well-being. Mindfulness and loving-kindness meditation also enhance emotional regulation and psychological well-being. This narrative and theoretical review explores the convergence of these therapies, highlighting their overlapping neurobiological, psychological, and phenomenological effects. Both modalities influence the amygdala, hippocampus, and default mode network, and may improve psychological flexibility, empathy, and neuroplasticity. Integrating meditation with psychedelic or MDMA-assisted therapy could stabilize insights gained during altered states, promote sustained benefits, and reduce distress during therapy. Future research should examine structured protocols combining these approaches.

Successful treatment of intractable MDMA adverse reactions using acupuncture and traditional Chinese medicine

Journal of Psychedelic Studies April 2, 2025 Hope Kronman, Alison Locker, Abdi Assadi et al.

A person experienced persistent insomnia, anxiety, and tinnitus for months after MDMA therapy, symptoms that did not resolve with Western medical approaches. Her symptoms eventually improved when treated within a Traditional Chinese Medicine framework. The authors argue that psychedelic treatment, particularly during the integration phase, may benefit from techniques that address energies not recognized by Western medicine.

The mindful use of psychiatric medication: Report from the Tel Aviv Psychoactive Clinic Project and a proposed model for psychiatric care

Journal of Psychedelic Studies January 15, 2025 Ido Hartogsohn, Yaron Yavelberg, Omry Ben Ezra

A pilot study with 110 participants taking psychiatric medications tested workshops that combined education about their condition and medication with guided, mindful ingestion in a supportive group setting. Survey responses from 33 participants showed significantly improved understanding of their medical conditions and prescribed drugs. Interviews revealed strong interest in mindful medication use, benefit from the communal setting, and themes of greater satisfaction and improved ability to benefit from the prescribed drug. The results suggest that non-pharmacological tools can improve outcomes of prescription drug use, supporting the need for further research.

Personal and social connection to psychedelics is associated with lower drug use stigma among psychiatrists in the United States

Journal of Psychedelic Studies September 17, 2024 Adam W. Levin, Aryan Sarparast, Paul B Nagib et al.

Among a sample of 180 American psychiatrists (mean age 48.4, 65.5% male, 24.1% trainees), about one-third (32.8%) reported personal use of and social connection to psychedelics. Psychiatrists with such personal connection tended to be younger and have fewer years of practice. Those with personal and social connection were more likely to disagree that using illegal drugs is morally wrong, that users should go to prison, are weak-minded, have no future, are poorly educated, are dishonest, or make them angry. Personal and social proximity to psychedelics is associated with less stigma toward drug use and people who use drugs.

Change in occupational burnout measures in emergency medical service workers after a psychedelic experience induced by a single self-administered dose of psilocybin mushrooms

Journal of Psychedelic Studies September 9, 2024 Ana Ferreira, Sharon Martindale, David Luke

A single therapeutic dose of psilocybin mushrooms, self-administered by five Emergency Medical Service Workers (EMSWs), was linked to visible improvements in several measures of occupational burnout two weeks after the session, with gains remaining stable at two months. Participants reported strong subjective experiences—psychological insights and emotional breakthroughs—that they saw as key to the positive outcome. The naturalistic field study suggests psilocybin may offer an alternative approach to address the high rates of psychological distress among EMSWs, potentially benefiting both workers and patient care quality.

Client treatment preferences in psychedelic-assisted therapy for depression in participants with depressive symptoms

Journal of Psychedelic Studies July 11, 2024 Alyssa B. Oliva, Mitch Earleywine, Fiona Low et al.

In a survey of 635 adults in the United States, the importance people place on having a therapist of the same gender or same race differs by the type of therapy and by the participant's own race and gender. For both cognitive behavioral therapy (CBT) and psychedelic-assisted therapy (PAT), racial and ethnic minority participants and female participants rated a same-gender practitioner as more important than did White or male participants. A same-gender CBT therapist was rated as more important than a same-gender PAT guide.

Are first responders interested in psychedelics? Assessing previous use, interest, and willingness to participate in psychedelic-assisted therapy

Journal of Psychedelic Studies April 2, 2024 Sonia M. Brodie, Chelsea Stunden, Jay A. Olson et al.

First responders such as firefighters and police officers experience high rates of post-traumatic stress disorder, depression, and anxiety. A survey of 102 first responders in Canada and the United States found that they reported higher distress and illicit drug use than the general population, and few who sought professional treatment felt it helped. Most respondents expressed interest in LSD- or marijuana-assisted therapy, with preferences about setting, therapist presence, and dose influencing their willingness to participate. The findings suggest that psychedelic therapy may be especially relevant for this population.

Of pharmakon: Hallucination in Amerindian perspectivism and speculative materialism

Journal of Psychedelic Studies June 16, 2022 Ignas Šatkauskas

The paper examines how the concepts of hallucination and psychedelic experience carry Western presuppositions about body and soul, nature and culture. It contrasts Viveiros de Castro's Amerindian perspectivism, which suspends assumptions of unreality, with Meillassoux's speculative materialism, where hallucination appears as an imitation of the real. This debate relates to the naturalization of spirituality. The critique extends to terms like psychedelic and entheogen. By revisiting the Matsigenka concept of kepigari and Derrida's pharmakon, the authors suggest that pharmakon offers a useful comparative tool for indigenous thought and psychedelic philosophy. They interpret psychedelics as an existential medicine with ambiguous, indeterminate possibilities.
