Mescaline (3,4,5-trimethoxyphenethylamine) is a classic serotonergic psychedelic with a history of indigenous ceremonial use. There is renewed scientific interest in mescaline because of the potential psychiatric benefits of psychedelic-assisted therapy. Mescaline primarily exerts its psychoactive effects through serotonin-2A (5-HT 2A ) receptor agonism. There is a lack of controlled clinical...
After becoming notorious for its use as a party drug in the 1980s, 3,4-methylenedioxy-methampetamine (MDMA), also known by its street names "molly" and "ecstasy," has emerged as a powerful treatment for post-traumatic stress disorder (PTSD). There are extensive data about the risk profile of MDMA. However, the literature is significantly biased. Animal models demonstrating neurotoxic or adverse...
Ketamine, an arylcyclohexylamine dissociative anesthetic agent, has evolved into a versatile therapeutic. It has a rapid-onset, well-understood cardiovascular effects and a favorable safety profile in clinical use. Its enantiomeric compound, esketamine, was approved by the Food and Drug Administration in 2019 for both treatment-resistant depression and major depressive disorder with suicidal...

Psychedelic drugs have recently emerged as plausibly effective pharmacological agents for the management of depression, anxiety, and other neuropsychiatric conditions, including those that are treatment-resistent. The latter half of the 20th century marked a revolution in the treatment of mental illnesses, exemplified by the introduction of selective serotonin reuptake inhibitors and other...
Lysergic acid diethylamide (LSD) is a hallucinogenic agent. In the mid-20th century, it was used to augment psychoanalysis and to treat alcohol use disorder. However, LSD was banned in 1970 in part because of concerns that it could bring about or exacerbate mental illness. Its therapeutic potential remains incompletely understood. While uncontrolled recreational use of LSD can, in rare...
N,N-dimethyltryptamine (DMT) is a naturally occurring serotonergic psychedelic found in natural plants around the globe. As the main psychoactive component in ayahuasca, which also contains monoamine oxidase inhibitors, DMT has been consumed as plant-based brew by indigenous peoples for centuries. Further research is required to delineate the therapeutic utility of DMT. Although previous...
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. Despite initial concerns that psilocybin could cause psychosis, contemporary research has demonstrated that psilocybin is...
Abstract: Psychedelic-assisted therapy (PAT) is increasingly used for trauma-related disorders, raising ethical questions beyond client safety. We argue that PAT clients have epistemic needs and clinicians have corresponding obligations that call for epistemic humility and discipline, which are essential for regulating foreseeable epistemic risks and for PAT's ethical structure. Drawing on...
Abstract This paper develops a phenomenological account of the therapeutic significance of psychedelic-induced mystical experience, drawing on the philosophy of Maurice Merleau-Ponty. The central argument holds that the enduring therapeutic benefits of psychedelics emerge through a radical transformation in the structure of lived experience. Two prominent objections to the therapeutic value of...
