This meta-analysis investigates the effect of classic psychedelic drugs on empathy and focuses on cognitive and emotional empathy measured using the Multifaceted Empathy Test (MET). Empathy entails the ability to understand and share the feelings of another and is a significant component of social interaction. Several studies have examined the effects of psy...
5-MeO-DMT is a psychedelic substance with a short duration of action and intensive effects. Its therapeutic efficacy and practicality may significantly surpass those of classical psychedelics such as ayahuasca and LSD. This retrospective ethnographic inquiry features a woman in her mid-thirties who witnessed her mother's violent suicide and its bloody afterm...

IntroductionPsilocybin, a naturally occurring serotonergic agonist in some mushroom species, has shown promise as a novel, fast-acting pharmacotherapy seeking to overcome the limitations of conventional first-line antidepressants. Studying psilocybin effects on cognition and emotional processing may help to clarify the mechanisms underlying the therapeutic p...
BACKGROUND: Serotonergic psychedelics, such as psilocybin, alter perceptual and cognitive systems that are functionally integrated with the amygdala. These changes can alter cognition and emotions that are hypothesized to contribute to their therapeutic utility. However, the neural mechanisms of cognitive and subcortical systems altered by psychedelics are n...
“Pretty girls don't buy cocaine,” Greta1 says and laughs as she walks out the front door.My hands and face sting as I stand frozen in the entryway and hear her start the car. I'd asked my twenty-two-year-old daughter where she got the money to feed the addictions she was battling.Over the past three years, she'd chosen a few subpar boyfriends who introduced ...
The serotonergic psychedelic psilocybin acutely induces changes in emotional states. However, it remains unresolved whether psilocybin acutely modulates emotionally-relevant amygdala reactivity to emotions, a brain region critically involved in emotion processing. Using functional magnetic resonance imaging (fMRI), we examined in 26 healthy individuals wheth...
BackgroundSince 2006 chocolate containing psilocin is circulating in The Netherlands. Psilocin is a psychoactive substance derived from psychedelic mushrooms and known to be hard drugs. Consuming psilocin can cause symptoms such as hallucinations, fear and panic attacks and sympathomimetic effects. These effects can last for approximately 6 hours.Case descri...
Serotonergic psychedelics, such as psilocybin and LSD, have garnered significant attention in recent years for their potential therapeutic effects and unique mechanisms of action. These compounds exert their primary effects through activating serotonin 5-HT2A receptors, found predominantly in cortical regions. By interacting with these receptors, serotonergi...
This retrospective study presents the case of a young woman in her mid-twenties who suffered from insecurity and abandonment-related anxiety, which intensified after a breakup of her relationship. Her parents' alcoholism and schizophrenia, as well as emotional and physical violence, had been a part of her childhood, but they had appeared 'normal' to her. Her...

OBJECTIVE: The primary aim of this qualitative study was to delineate psychological mechanisms of change in the first randomized controlled trial of psilocybin-assisted psychotherapy to treat alcohol use disorder (AUD). Theories regarding psychological processes involved in psychedelic therapy remain underdeveloped. METHOD: Participants (N = 13) mostly ident...
Interest in the therapeutic potential of psilocybin across a broad range of neuropsychiatric disorders is rapidly expanding. Despite promising clinical data and tremendous public enthusiasm, complimentary basic and translational studies - which are critical for advancing our understanding of psilocybin's biological effects and promoting innovation - have bee...
Classic psychedelics, such as psilocybin, act on the brain's serotonin system and produce striking psychological effects. Early work in the 1950s and 1960s and more recent controlled studies suggest benefit from psychedelic treatment in a number of conditions. A few case reports in recreational users and a single experimental study suggest benefit in patient...
BackgroundMusic listening is a staple and valued component of psychedelic therapy, and previous work has shown that psychedelics can acutely enhance music-evoked emotion.AimsThe present study sought to examine subjective responses to music before and after psilocybin therapy for treatment-resistant depression, while functional magnetic resonance imaging (fMR...
BackgroundPsilocybin is a serotonin type 2A (5-HT2A) receptor agonist and naturally occurring psychedelic. 5-HT2A receptor density is known to be associated with body mass index (BMI), however, the impact of this on psilocybin therapy has not been explored. While body weight-adjusted dosing is widely used, this imposes a practical and financial strain on the...
Introduction There is a growing and renewed interest in the use of hallucinogenic drugs in the treatment of psychiatric disorders, especially since the FDA approval of ketamine treatment for resistant depression. The response to hallucinogenic psychedelic substances (ayahuasca, psilocybin, LSD, ketamine) in the treatment of depression and addictions calls fo...
Abstract We present the set and setting of the velada, the Mazatec ritual of divination and healing. We highlight the subjective experiences of individuals who consumed sacred mushrooms and interpret them from their cultural and community contexts, but also from findings derived from experimental and neuroscientific research. We understand that the experienc...
RationaleA general feeling of disconnection has been associated with mental and emotional suffering. Improvements to a sense of connectedness to self, others and the wider world have been reported by participants in clinical trials of psychedelic therapy. Such accounts have led us to a definition of the psychological construct of 'connectedness' as 'a state ...
