Trajectories of psychedelic-assisted change
Despite growing interest in psychedelic-assisted psychotherapy, research investigating the psychotherapeutic components is lacking. This leaves unanswered questions regarding the psychotherapy's necessity and form. This observational study addresses this gap by measuring the outcomes of a psilocybin truffle retreat, followed by the outcomes of two psychotherapy interventions that targeted psychological content from the retreat ( n = 50). Particip…
Comparative effects of ayahuasca and breathwork on self-reported cognitive flexibility, emotion regulation, positive affect, and sleep quality
Background and aimsResearch on classical psychedelics like ayahuasca is increasingly focused on treating mental disorders and enhancing well-being. Ayahuasca has shown promise in improving cognitive flexibility, emotion regulation, and sleep, though findings are mixed and further research is needed. This study tracked participants over three months, assessing cognitive flexibility, positive affect, emotion regulation, and sleep before and after a…
Trait mindfulness and personality characteristics in a microdosing ADHD sample
MD induced changes in otherwise stable traits. Future placebo-controlled studies are warranted to confirm whether these changes occur in a controlled setting
A Preliminary Inventory of Kratom (Mitragyna Speciosa) Products and Vendors on the Darknet and Cryptomarkets
In recent years, the online sale of kratom ( Mitragyna speciosa ), a Southeast Asian plant with both medicinal and psychoactive properties, has raised health concerns mainly due to the uncontrolled diffusion of adulterated kratom-related products. This exploratory study provides, for the first time, a snapshot of the availability of kratom products on the darknet which has been further validated by data searches on the surface web. A total of 231…
Decreases in State and Trait Anxiety Post-psilocybin
Anxiety disorders are the most common type of psychiatric disorders among Western countries. Evidence-based treatment modalities including pharmacological and cognitive-behavioral therapy result in deficient treatment responses. Historical and recent research suggests psychedelic drugs may be efficacious in alleviating anxiety-related symptoms among healthy and clinical populations. The main aim of the present study was investigation of the effec…
A Comparison of Acute Neurocognitive and Psychotomimetic Effects of a Synthetic Cannabinoid and Natural Cannabis at Psychotropic Dose Equivalence
Due to differences in potency, efficacy, and affinity for CB1 receptors, similarities and differences in psychoactive effect profiles of natural cannabis and synthetic cannabinoids (SCs) cannot reliably be derived from equipotent dose comparisons. Instead, the current study proposes to compare the intrinsic psychoactive effects of natural cannabis (THC) and an SC, JWH-018, at psychotropic dose equivalence. Participants from two placebo-controlled…
Self-Rated Effectiveness of Microdosing With Psychedelics for Mental and Physical Health Problems Among Microdosers
Background: There is a growing interest in the use of psychedelic substances for health related purposes, including symptom relief for disorders like anxiety, depression, and pain. Although the focus of recent clinical trials has been on high doses of these substances, anecdotal evidence suggests that low (micro) doses are also effective, and may be more suitable for certain conditions. Nonetheless, empirical evidence regarding the efficacy of mi…
A First-in-Man Study with 4-Fluoroamphetamine Demonstrates it Produces a Mild Psychedelic State
The phenethylamine 4-fluoroamphetamine (4-FA) is a so-called novel psychoactive substance with a chemical structure resembling that of amphetamine and MDMA. Since 4-FA users report their subjective experience ranges between the effects induced by amphetamine and MDMA, and it is known that both substances can produce an altered state of consciousness, this study tests whether 4-FA induces a psychedelic state. A placebo-controlled two-way crossover…
Sub-Acute Effects of Psilocybin on Empathy, Creative Thinking, and Subjective Well-Being
Creative thinking and empathy are crucial for everyday interactions and subjective well-being. This is emphasized by studies showing a reduction in these skills in populations where social interaction and subjective well-being are significantly compromised (e.g., depression). Anecdotal reports and recent studies suggest that a single administration of psilocybin can enhance such processes and could therefore be a potential treatment. However, it …
Mental health of a self-selected sample of psychedelic users and self-medication practices with psychedelics
A substantial number of people worldwide suffer from mental health problems during their lifetime. First-line treatments are not effective for everybody. Recent studies suggest that psychedelic drugs have high therapeutic potential for a variety of mental disorders. This survey study aimed to assess the tendency of psychedelic users to self-medicate with psychedelics and to compare the effectiveness of self-administered psychedelics to treat thei…
