Pharmacological effects of methylone and MDMA in humans

Frontiers in Pharmacology February 17, 2023 Lourdes Poyatos, Clara Pérez‐mañá, Olga Hladun et al. 26 citations

Methylone is one of the most common synthetic cathinones popularized as a substitute for 3,4-methylenedioxymethamphetamine (MDMA, midomafetamine) owing to its similar effects among users. Both psychostimulants exhibit similar chemistry (i.e., methylone is a β-keto analog of MDMA) and mechanisms of action. Currently, the pharmacology of methylone remains scarcely explored in humans. Herein, we...

The Effects of Peripubertal THC Exposure in Neurodevelopmental Rat Models of Psychopathology

International Journal of Molecular Sciences February 15, 2023 Martina di Bartolomeo, Tibor Stark, Serena di Martino et al. 23 citations

Adolescent exposure to cannabinoids as a postnatal environmental insult may increase the risk of psychosis in subjects exposed to perinatal insult, as suggested by the two-hit hypothesis of schizophrenia. Here, we hypothesized that peripubertal Δ9-tetrahydrocannabinol (aTHC) may affect the impact of prenatal methylazoxymethanol acetate (MAM) or perinatal THC (pTHC) exposure in adult rats. We...

Experiences of psilocybin treatment for clinical conditions: A qualitative meta‐synthesis

International Journal of Mental Health Nursing February 13, 2023 Marie Crowe, Jenni Manuel, Dave Carlyle et al. 18 citations

Abstract There is increasing clinical interest in the use of psilocybin. There is emerging evidence of the efficacy of psilocybin for the treatment of a range of clinical conditions. Mental health nurses have a unique set of skills for caring for people who are hallucinating. To expand these skills to meet the developing clinical interest in the therapeutic use of psilocybin, it is helpful to...

The History, Legalization and Potentials of Psilocybin-Assisted Psychotherapy

Journal of Scientific Exploration February 11, 2023 Jeffery Heilman 2 citations

The potential benefits and deficits of the chemical compound psilocybin, particularly when paired with psychotherapeutic interventions, have been increasingly apparent top­ics of interest in social, academic, and scientific circles. The unusual nature of psilocybin poses many questions in Western culture. Three of them, which will be discussed in the following review, are (1) What is...

Examining associations between MDMA/ecstasy and classic psychedelic use and impairments in social functioning in a U.S. adult sample

Scientific Reports February 11, 2023 Grant Jones, Joshua Lipson, Erica Wang 2 citations

Abstract Impairment in social functioning is a common source of morbidity across many mental health disorders, yet there is a dearth of effective and easily implemented interventions to support social functioning. MDMA/ecstasy and classic psychedelics (psilocybin, LSD, peyote, mescaline) represent two potential treatments for impairments in social functioning, as evidence suggests these...

N,N‐dimethyltryptamine affects electroencephalography response in a concentration‐dependent manner—A pharmacokinetic/pharmacodynamic analysis

CPT: Pharmacometrics & Systems Pharmacology February 10, 2023 Emma Eckernäs, Christopher Timmermann, Robin Carhart-Harris et al. 15 citations

Abstract N,N‐dimethyltryptamine (DMT) is a psychedelic substance and is being used as a research tool in investigations of the neurobiology behind the human consciousness using different brain imaging techniques. The effects of psychedelics have commonly been studied using electroencephalography (EEG) and have been shown to produce suppression of alpha power and increase in signal diversity....

Cannabis use and first onset Schizophrenia-like psychosis after traumatic brain injury in a patient with intracranial bullet

Journal of Substance Use February 7, 2023 M. Ergelen, M. Yalçın, Fikret Ferzan Gıynaş et al.

ABSTRACT Traumatic brain injury (TBI) is an important cause of mortality and morbidity worldwide. Cannabis use disorder and psychosis are rare but serious comorbidities seen after TBI. Recent studies indicate that the use of cannabis for self-medication may increase after TBI. Schizophrenia-like psychosis (SLP) is also seen, generally showing a late and gradual onset after TBI. Especially in...

From autopoiesis to self-optimization: Toward an enactive model of biological regulation

bioRxiv Preprint Server February 5, 2023 Tom Froese, Natalya Weber, Ivan Shpurov et al. 6 citations preprint

The theory of autopoiesis has been influential in many areas of theoretical biology, especially in the fields of artificial life and origins of life. However, it has not managed to productively connect with mainstream biology, partly for theoretical reasons, but arguably mainly because deriving specific working hypotheses has been challenging. The theory has recently undergone significant...

Hofmann vs. Paracelsus: Do Psychedelics Defy the Basics of Toxicology?—A Systematic Review of the Main Ergolamines, Simple Tryptamines, and Phenylethylamines

Toxics February 3, 2023 Luis Alberto Henríquez-Hernández, Jaime Rojas-Hernández, Domingo Jesús Quintana Hernández et al. 21 citations

Psychedelics are experiencing a strong renaissance and will soon be incorporated into clinical practice. However, there is uncertainty about how much harm they can cause at what doses. This review aimed to collect information on the health-hazardous doses of psychedelic substances, to be aware of the risks to which patients may be subjected. We focused on ergolamines, simple tryptamines, and...

Severe length‐dependent peripheral polyneuropathy in a patient with subacute combined spinal cord degeneration secondary to recreational nitrous oxide abuse: A case report and literature review

Clinical Case Reports February 1, 2023 Ventzislav Bonev, M. Wyatt, Matthew J. Barton et al.

Nitrous oxide abuse can have detrimental effects on the central and peripheral nervous systems. This case study report aims to demonstrate a combination of severe generalized sensorimotor polyneuropathy and cervical myelopathy related to vitamin B12 deficiency following nitrous oxide abuse. We present a clinical case study and literature review examining primary research—published between 2012...
