Based on its in vitro profile and preliminary evidence, 4-bromo-2,5-dimethoxyphenethylamine (2C-B) may have psychoactive properties that are similar to 3,4-methylenedioxymethamphetamine (MDMA) and psilocybin, which are investigated for the treatment of posttraumatic stress disorder and depressive disorders. We compared acute effects of 2C-B (10, 20, and 30 m...
The proposed open-label, controlled study at the Johns Hopkins Center for Psychedelic and Consciousness Research (CPCR) will test the following primary hypotheses in adult patients with chronic PTSD who are currently taking a serotonin reuptake inhibitor: psilocybin therapy will be feasible and safe for participants, significantly remediate PTSD symptoms, an...
Abstract The Czech Republic, like many European countries, continues to face significant challenges in treating substance use disorders (SUDs), with high relapse rates and complex comorbidities often linked to trauma and mental illness. Psychedelic-assisted psychotherapy (PAP) has re-emerged internationally as a promising therapeutic modality, although avail...
Aims: Recently the therapies that utilize psychedelics have emerged as promising treatments for mood disorders, trauma-related disorders, and substance use disorders. While there is a growing body of research comparing various interventions directly, the majority of available research has been conducted in an indirect manner; therefore, Network Meta-Analysis...
Mystical dynamics-the notion that mystical oneness may unfold involving ego disintegration, renewal, and luminous light-has been discussed anecdotally by psychedelic researchers and therapists but has not yet been empirically examined in controlled settings. This study investigated the occurrence and dose-dependency of mystical dynamics in healthy participan...
The primary objective of this study is to investigate the safety, feasibility, and tolerability of psilocybin treatment in individuals with functional impairment due to psychiatric symptoms. The secondary objective of this study is to determine whether individuals with functional impairments due to psychiatric symptoms will experience statistically significa...
In our original case report we provide detailed accounts of two research participants who reported the emergence of spontaneously recovered, previously forgotten traumatic memories of sexual assaults during psilocybin treatment. In their commentary of this article, Kangaslampi et al. argue that we preemptively label the experiences as dissociated traumatic m...
Background: Existing tools assess psychedelic experiences, but none specifically measure altered processing of traumatic memories-a key mechanism in trauma-focused therapies and psychotherapy in general. The helioscope effect describes how psychedelics like psilocybin and 3,4-methylenedioxymethamphetamine (MDMA) enable revisiting challenging or traumatic exp...
BackgroundThe Altered States of Consciousness Scale (3/5D-ASC or 11-ASC) is widely used to assess non-ordinary states of consciousness, particularly for psychedelic research. However, its original dimensional model (3D-ASC within 5D-ASC) and later 11-subscale structure (11-ASC) have a hierarchically incompatible higher/lower-order structure. Although the 11-...
Psychedelic-assisted psychotherapy has demonstrated efficacy in treating individual mental health conditions such as addiction, anxiety, depression, and post-traumatic stress disorder. However, current research predominantly focuses on individual experiences, overlooking the relational and systemic factors that influence healing and long-term therapeutic out...
In their recent case report article, Peck and colleagues suggested that two patients recovered dissociated traumatic memories during psilocybin treatment for anorexia nervosa. These case reports are of clinical and scientific interest and confirm that psychedelics may induce vivid memory-like experiences. However, the reports warrant scrutiny. Here, based on...
Background: Post-traumatic stress disorder (PTSD) is a debilitating condition leading to significant personal and societal burden. Standard treatments frequently demonstrate limited efficacy, leading to persistent symptoms and high dropout rates. Psilocybin has shown promise in treating depression, a condition that is often comorbid with PTSD. We aimed to ex...
Background: Psilocybin-assisted psychotherapy (PAP) may be an effective intervention for a range of mental disorders. However, there appears to be a relative lack of qualitative evidence to complement emerging quantitative findings. To our knowledge, no reviews have systematically mapped the literature on qualitative studies on PAP for the treatment of menta...
This study explores how individuals from ethnoracially marginalized backgrounds engage with psychedelic substances for psychological healing, cultural reconnection, and resistance to structural neglect in mainstream health care systems. Based on 23 in-depth interviews and participant-observation within a psychedelic preparation and integration training progr...
The Hamas-led attack in southern Israel on October 7, 2023 was one of the deadliest terror attacks in history, resulting in 1,182 fatalities, over 4,000 wounded, and 251 taken hostage1. The Nova festival, an 18-hour rave held in the Gaza Envelope region, suffered the highest casualties in the attack, with over 370 killed. For the Nova attendees, the highligh...
This is an open-label psilocybin-assisted therapy study that will examine the safety and tolerability of psilocybin-assisted therapy in the offspring of genocide survivors with mood and anxiety disorders. The study will also investigate the efficacy of psilocybin-assisted therapy in reducing symptoms such as depression, anxiety and stress, as well as changes...
Introduction In recent years, psychiatry has witnessed a renaissance in the investigation of psychedelic compounds, a broad class of psychoactive substances that induce altered states of consciousness, often characterized by changes in perception, mood, and cognition, which were largely shelved following regulatory crackdowns in the 1970s. The renewed intere...
Psychedelic Minimalism: The Case Against Music in Psychedelic Therapy SettingsIn response to: Kaelen et al. (2018), “The Hidden Therapist: Evidence for a Central Role ofMusic in Psychedelic Therapy.”Introduction: Reframing the Role of SettingIn recent years, renewed attention has been given to the centrality of set and setting inpsychedelic-assisted therapy....
Background: Current trauma treatment options often fail to meet patients' needs. Despite the availability of established interventions, many trauma treatments fail to adequately meet patients' needs. In parallel, there has been renewed scientific and public interest in the therapeutic potential of psychedelics and related compounds, accompanied by increasing...
Little is known about motives of healthy volunteers to participate in psychedelic trials and how they appraise their study experience retrospectively. This paper explored reasons why healthy people register for psychedelic trials, factors that they considered to contribute to either positive or negative study experiences, and under which circumstances they w...
