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…
A mixed methods study exploring food insecurity and diet quality in households accessing food clubs in England
This study is the first in the UK to explore potential diet, food security and wellbeing impacts of food clubs. Ongoing impact evaluation will enable optimisation of interventions for the populations they serve, such as inviting other organisations/groups to attend/be available for members
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…
Psychedelic intimacy
ObjectiveEngaging in practices of intimacy meant to develop and sustain intimacy can be beneficial for couples. Psychoactive substances such as 3,4-Methylenedioxymethamphetamine (MDMA) have shown to facilitate bonding within couples and it is hypothesised that classic psychedelics, due to their property to increase prosocial behaviours, can similarly promote interactional intimacy. This study explores shared experiences of altered states of consc…
A phase 1/2 trial to assess safety and efficacy of a vaporized 5-methoxy-N,N-dimethyltryptamine formulation (GH001) in patients with treatment-resistant depression
Administration of GH001 to a cohort of 16 patients with TRD was well tolerated and provided potent and ultra-rapid antidepressant effects. Individualized dosing with up to three doses of GH001 on a single day was superior to single dose administration. Clinical Trial registration : Clinicaltrials.gov Identifier NCT04698603
Methylphenidate as a treatment option for substance use disorder
A transition in viewing mental disorders from conditions defined as a set of unique characteristics to one of the quantitative variations on a collection of dimensions allows overlap between disorders. The overlap can be utilized to extend to treatment approaches. Here, we consider the overlap between attention-deficit/hyperactivity disorder and substance use disorder to probe the suitability to use methylphenidate as a treatment for substance us…
Examining the Psychoactive Differences between Kratom Strains
Kratom ( Mitragyna speciosa ) is a Southeast Asian plant containing various alkaloids that induce pharmacological effects in humans. In Western countries, online vendors sell a variety of different kratom strains which are marketed to have distinct effect profiles. However, as of yet such marketing claims are unsubstantiated, and therefore the current study investigated whether differently colored kratom products can induce distinct effects, as s…
Cannabis Use and Neuroadaptation
Currently, the assessment of the neurobehavioral consequences of repeated cannabis use is restricted to studies in which brain function of chronic cannabis users is compared to that of non-cannabis using controls. The assumption of such studies is that changes in brain function of chronic users are caused by repeated and prolonged exposure to acute cannabis intoxication. However, differences in brain function between chronic cannabis users and no…
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…
An experience with Holotropic Breathwork is associated with improvement in non-judgement and satisfaction with life while reducing symptoms of stress in a Czech-speaking population
BackgroundHolotropic breathwork (Grof (R) Breathwork), was developed by Stanislav Grof and Christina Grof as a 'non-drug' alternative technique to evoke altered states of consciousness (ASC). Interestingly, although HBW has been anecdotally reported to evoke experiences and mental health effects corresponding to those of psychedelic substances, the scientific literature on the matter is scarce.AimsThe objective of this study was to assess the (su…
Sub-acute and long-term effects of ayahuasca on mental health and well-being in healthy ceremony attendants
Background and aims There is a growing body of evidence suggesting that the psychedelic plant tea, ayahuasca, holds therapeutic potential. Uthaug et al. (2018) demonstrated that a single dose of ayahuasca improved mental health sub-acutely and 4-weeks post-ceremony in healthy participants. The present study aimed to replicate and extend these findings. A first objective was to assess the sub-acute and long-term effects of ayahuasca on mental heal…
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…
