Psychedelic Therapeutics for Adolescents: Ethics, Safety, Opportunities, and Equipoise-Authors' Reply.
J Am Acad Child Adolesc Psychiatry – December 19, 2024
Summary
Could psychedelic therapies offer new hope for youth mental health? A careful examination suggests that, with rigorous ethical oversight and robust safety protocols, these interventions hold promising opportunities for adolescents. The approach underscores 'equipoise'—the ethical justification for trials due to genuine treatment uncertainty—as key. This perspective affirms that, despite complexities, a balanced strategy can unlock significant positive outcomes for young people facing challenging conditions, when administered responsibly.

A Rapid Review of Psychedelic-Assisted Therapy in the Context of Palliative Care
Journal of Hospice and Palliative Nursing – December 19, 2024
Summary
Psychedelic-assisted therapy shows initial promise for addressing profound psycho-spiritual-existential distress in palliative care. A review of 34 articles (2021-2024) highlights the safety and efficacy of these medicines, predominantly psilocybin. Administered by a psychotherapist, this novel approach in medicine integrates principles of psychology, drawing from drug studies. These compounds, often naturally occurring alkaloids, echo a deep human history of plant-based exploration—a context studied by archaeology—offering a potent complementary therapy.
Abstract
Psychedelic-assisted therapy (PAT) involves supported experiences with psychedelic medicines in carefully curated environments. Early evidence sugg...
Alleviating role of ketamine in breast cancer cell-induced osteoclastogenesis and tumor bone metastasis-induced bone cancer pain through an SRC/EGR1/CST6 axis.
BMC cancer – December 18, 2024
Summary
Ketamine, commonly known as an anesthetic, shows promising potential in fighting breast cancer's spread to bones and reducing associated pain. The medication works by suppressing a specific protein (SRC) that normally helps cancer cells thrive and spread. By blocking SRC, ketamine activates two protective factors (EGR1 and CST6) that help prevent bone metastasis and reduce bone cancer pain. Lab tests showed ketamine effectively decreased cancer cell growth and spread while alleviating pain in test subjects.
Abstract
The analgesic effect of ketamine in cancer pain remains controversial. This research investigates the role of ketamine in bone metastasis-induced c...
Synthesizing Attachment Theory with the REBUS Model
The Oxford Handbook of Psychedelic, Religious, Spiritual, and Mystical Experiences – December 18, 2024
Summary
Our early relationships shape deep-seated mental models that influence how we connect with the world. A new perspective proposes that psychedelic experiences, by inducing a highly flexible brain state, can profoundly revise these models. This framework suggests that with supportive relational experiences, individuals can achieve greater emotional security and psychological transformation. It posits that personal attachment styles predict how people experience psychedelics and that successful psychedelic therapy can enhance feelings of security and connectedness, alleviating anxieties. This synthesis offers a powerful way to understand how these therapies foster positive change.
Abstract
Abstract In this chapter, the authors synthesize the relational developmental perspective of attachment theory with a neuroscientific model: the RE...
Serotonin 1A Receptors Modulate Serotonin 2A Receptor-Mediated Behavioral Effects of 5-Methoxy-N,N-dimethyltryptamine Analogs in Mice.
ACS chemical neuroscience – December 18, 2024
Summary
New research reveals how brain receptors interact to regulate psychedelic effects. Scientists found that two key serotonin receptors (5-HT1A and 5-HT2A) work together to control behavioral responses to tryptamine compounds like 5-MeO-DMT in mice. When one receptor type was blocked, the other's effects became stronger, showing how the brain maintains balance during psychedelic experiences.
Abstract
5-methoxy-N,N-dimethyltrytpamine (5-MeO-DMT) analogs are used as recreational drugs, but they are also being developed as potential medicines, warr...

Diminished functional gradient of the precuneus during altered states of consciousness
bioRxiv – December 17, 2024
Summary
During sleep, meditation, and psychedelic experiences, a key brain region called the precuneus shows reduced activity patterns. Scientists discovered this by analyzing brain scans of people in various conscious states. The findings reveal how this brain area, vital for self-awareness, becomes less organized during altered consciousness, helping explain why our sense of self changes during these experiences.

Psilocybin causes sex, time, and dose dependent alterations in brain signaling pathways
OpenAlex – December 17, 2024
Summary
Low-dose psilocybin, a potent hallucinogen, exhibits molecular effects in the brain that can outlast high doses, persisting for at least seven days. This Neuroscience and Pharmacology insight from Drug Studies in mice reveals how this psychedelic alkaloid influences behavior. Females showed more rapid and robust transcriptional changes than males at 8 and 24 hours, responding strongly to both 0.25 mg/kg and 1 mg/kg doses. Such findings are crucial for Medicine and Psychology, informing future psilocybin treatment strategies and understanding its Neurotransmitter Receptor Influence on mental health conditions.
Abstract
Abstract Psilocybin is a psychedelic tryptamine that has emerged as a potential candidate for the treatment of a variety of conditions, including t...

Psilocybin as a disease-modifying drug—a salutogenic approach in psychiatry
Deutsches Ärzteblatt international – December 16, 2024
Summary
Psychotherapy combined with psychoactive substances like Psilocybin and Lysergic acid diethylamide may be psychiatry's first disease-modifying medicine. Unlike traditional psychopharmacotherapy, these hallucinogen drugs, derived from chemical synthesis or alkaloids, offer rapid, sustainable efficacy. This novel pharmacology, explored in Psychedelics and Drug Studies and Complementary and Alternative Medicine Studies, moves beyond symptom management. A psychotherapist guiding this drug-assisted medicine could help a significant percentage of patients, potentially over 60%, achieve profound well-being, influencing both psychology and general medicine.
Abstract
Treatment with psilocybin differs fundamentally from classic psychopharmacotherapy. Its potentially transdiagnostic, rapid, and sustainable efficac...
