Abstract Background The recognition of emotions in facial expressions (REFE) is a core aspect of social cognition. Previous studies with the serotonergic hallucinogens lysergic acid diethylamide and psilocybin showed that these drugs reduced the recognition of negative (fear) faces in healthy volunteers. This trial assessed the acute and prolonged effects of a single dose of ayahuasca on the...

Introduction Psychedelics - including LSD (lysergic acid diethylamide), psilocybin, DMT (N, N-dimethyltryptamine), ayahuasca and mescaline - have an ancient history across various civilizations. In 1950, after LSD’s discovery by Hofmann, psychedelics enjoyed a short-lived relationship with psychiatry, before prohibitive legislature emerging in response to the recreational use in the mid-1960s....

Abstract The present study examines the association between the ceremonial use of ayahuasca—a decoction combining the Banistereopsis caapi vine and N,N-Dimethyltryptamine-containing plants—and changes in personality traits as conceived by the Five-Factor model (FFM). We also examine the degree to which demographic characteristics, baseline personality, and acute post-ayahuasca experiences...

Abstract Ayahuasca is a plant concoction containing N,N -dimethyltryptamine (DMT) and certain β-carboline alkaloids from South America. Previous research in naturalistic settings has suggested that ingestion of ayahuasca can improve mental health and well-being; however, these studies were not placebo controlled and did not control for the possibility of expectation bias. This naturalistic...

A novel analogue of psilocybin was produced by hybrid chemoenzymatic synthesis in sufficient quantity to enable bioassay. Utilizing purified 4-hydroxytryptamine kinase from Psilocybe cubensis, chemically synthesized 5-methylpsilocin (2) was enzymatically phosphorylated to provide 5-methylpsilocybin (1). The zwitterionic product was isolated from the enzymatic step with high purity utilizing a...

It is tough to write about psychedelics without a few gratuitous puns. Regardless, Michael Pollan’s “How to Change Your Mind” is definitely “mind expanding” and deserves my “highest” recommendation. Published in 2019, this book comprehensively and presciently covers a topic of increasing interest: whether psychedelic agents can revolutionize mental health. Pollan is not a Medical Doctor but is...

Serotonergic psychedelic drugs, such as psilocin (4-hydroxy-N,N-dimethyltryptamine), profoundly alter the quality of consciousness through mechanisms which are incompletely understood. Growing evidence suggests that a single psychedelic experience can positively impact long-term psychological well-being, with relevance for the treatment of psychiatric disorders, including depression. A...

Psychostimulants are used therapeutically and for illegal recreational purposes. Many of these are inhibitors of the presynaptic noradrenaline, dopamine, and serotonin transporters (NET, DAT, and SERT). According to their physicochemical properties, some might also be substrates of polyspecific organic cation transporters (OCTs) that mediate uptake in liver and kidneys for metabolism and...
