The use of psychoactive substances for ritual, spiritual and medicinal purposes stretches back into prehistory and has been a common feature of many diverse cultures and societies globally. Psychedelics, with their unique ability to amplify feelings of connectedness and openness, may have also served as tools for promoting tribal cohesion and trust in ancien...
BACKGROUND: The primary psychoactive drug in magic mushrooms, psilocybin, induces profound alterations in consciousness through the 5-HT2A receptor. This review consolidates current research findings to elucidate the pharmacology, safety profile, and clinical applications of psilocybin. AREAS OF UNCERTAINTY: Despite initial concerns that psilocybin could cau...
Psychiatry is in a growth phase in which several psychedelic medicines have entered its arena with great promise. Of these, presently, ketamine is the only medicine that may be legally prescribed. We hypothesize that at subanesthetic doses, ketamine produces a unique spectrum of altered states, ranging from psychoactive to deep ego-dissolving experiences, th...
To investigate the relationship between psychedelic microdosing and its effects on mental health, aiming to understand if microdosing can improve mental well-being. PubMed and Scopus were searched on December 25, 2022, using search terms related to psychedelics, microdosing, and mental health. The inclusion criteria focused on studies published between Janua...
HISTORY In the early part of twentieth century, these molecules were known as psychotomimetics, meaning that they create a state similar to psychosis. Later on, they were also termed as hallucinogens, but psychedelics usually do not cause hallucinations at a therapeutic dose. The name psychedelics for these substances was first given by Osmond in 1957, meani...

There has been increasing scientific and clinical interest in studying psychedelic and meditation-based interventions in recent years, both in the context of improving mental health and as tools for understanding the mind. Several authors suggest neurophysiological and phenomenological parallels and overlaps between psychedelic and meditative states and sugg...
Serotonergic hallucinogens also referred to as psychedelics, are psychoactive substances that profoundly alter perception, mood, and cognitive processes. These substances, historically intertwined with religious and cultural rituals, offer profound effects that extend beyond mere hallucinations to profoundly altered states of consciousness. Notable compounds...
Cannabis and classic psychedelics are controlled substances with emerging evidence of efficacy in the treatment of a variety of psychiatric illnesses. Cannabis has largely not been regarded as having psychedelic effects in contemporary literature, despite many examples of historical use along with classic psychedelics to attain altered states of consciousnes...
Psychedelics are classical hallucinogen drugs that induce a marked altered state of consciousness. In recent years, there has been renewed attention to the possible use of classical psychedelics for the treatment of certain mental health disorders. However, further investigation to better understand their biological effects in humans, their mechanism of acti...
Serotonergic psychedelics induce altered states of consciousness and have shown potential for treating a variety of neuropsychiatric disorders, including depression and addiction. Yet their modes of action are not fully understood. Here, we provide a novel, synergistic understanding of psychedelics arising from systematic reviews and meta-analyses of three h...
Clinical trials of psychedelics have provided support for their potential efficacy and safety. Although most combined a psychedelic with psychological support akin to psychotherapy, providing psychotherapy is costlier and more difficult to scale than providing only support to reduce harms. Trials with factorial designs can evaluate the individual effects of ...
The present study investigated differences in perceptions of psychedelic-assisted therapy between Black and White Americans, as well as factors that may influence these perceptions. A final sample of 294 adults (42% female, 44% Black/African American or Mixed Race (of Black/African ancestry), 56% White American; Mage = 36.3 years) completed an online survey ...
OBJECTIVE: This study invited providers who care for patients with eating disorders to inform engagement, communication, and collaboration with psilocybin-assisted psychotherapy interventions. METHOD: Medical and mental health providers who treat patients with eating disorders were recruited via professional referral networks and participant driven sampling ...
BACKGROUND: Pharmacological and nonpharmacological methods of inducing altered states of consciousness (ASCs) are becoming increasingly relevant in the treatment of psychiatric disorders. While comparisons between them are often drawn, to date no study has directly compared their neural correlates. METHODS: To address this knowledge gap, we directly compared...
Substances that change the states of consciousness have been used in the therapeutics of traditional cultures for hundreds of years. In the Western cultural circle, scientific curiosity and hope for a breakthrough in the treatment of various mental disorders constituted the basis of the first wave of research on humans with the use of psychedelics. After syn...
