Effects of Psilocybin-Assisted Therapy on Major Depressive Disorder. A Randomized Clinical Trial Alan K. Davis, PhD; Frederick S. Barrett, PhD; Darrick G. May, MD; Mary P. Cosimano, MSW; Nathan D. Sepeda, BS; Matthew W. Johnson, PhD; Patrick H. Finan, PhD; Roland R. Griffiths, PhD JAMA Psychiatry, 2020, E1-E9. doi : 10.1001/jamapsychiatry.2020.3285 IMPORTANCE : Major depressive disorder (MDD) is a substantial public health burden, but current treatments have limited effectiveness and adherence. Recent evidence suggests that 1 or 2 administrations of psilocybin with psychological support produces antidepressant effects in patients with cancer and in those with treatment-resistant depression. OBJECTIVE : To investigate the effect of psilocybin [...]

Stephens, Riwaj Bhagat, Christopher M. Jones, Wei Liu, Alexi R. Hernandez, Kerri S. Remmel and Adriana E. Palade The Open Neurology Journal, 2020, 14, 53-58. Doi : 10.2174/1874205X02014010053 Abstract : Background : Synthetic Cannabinoid (SC) use has emerged as a growing public health threat in the United States. Several unexpected cases, presenting with a constellation of unrelated symptoms, but all having toxicity linked to SC use, have been reported in the last decade (2010-2019). Methods : We report a cluster of several independent cases where patients were [...]

Schoeder, Cornelius Hess, Burkhard Madea, Jens Meiler, Christa E. Müller Forensic Toxicology, 2018, 36, 385-403. Doi : 10.1007/s11419-018-0415-z Abstract Purpose : In the present study we characterized a series of synthetic cannabinoids containing various heterocyclic scaffolds that had been identified as constituents of “Spice”, a preparation sold on the illicit drug market. All compounds were further investigated as potential ligands of the orphan receptors GPR18 and GPR55 that interact with some cannabinoids. Methods : The compounds were studied in radioligand binding assays to determine their affinity for [...]

The ancient ritual roots of shamanism constituted the context within which psychedelic experiences contributed selective influences to the evolution of human neuropsychology. Both shamanic psychology and ecopsychology involve a neuroepistemology that reflects the neurotransmitter effects of psychedelics on cognition. Shamanism contributed to the development of our ecopsychology through influences on psychological, social and cognitive evolution. Shamanism embodies the concept of animism, the notion of the spiritual essence of all [...]
Lire la suitePsychedelics as a Treatment for Alzheimer’s Disease Dementia Simon Andrew Vann Jones and Allison O’Kelly Cornwall Partnership NHS Foundation Trust, Liskeard, United Kingdom Frontiers in Synaptic Neuroscience, August 2020 | Volume 12 | Article 34 doi : 10.3389/fnsyn.2020.00034 Currently, there are no disease-modifying treatments for Alzheimer’s disease (AD) or any other dementia subtype. The renaissance in psychedelic research in recent years, in particular studies involving psilocybin and lysergic acid diethylamide (LSD), coupled with anecdotal reports of cognitive benefits from micro-dosing, suggests that they may have a therapeutic role in a range of psychiatric and neurological conditions due to their potential to stimulate neurogenesis, provoke neuroplastic [...]
Lire la suiteMinor Cannabinoids of Cannabis sativa L. Fabian Thomas & Oliver Kayser Journal of Medical Science, 2019, 88, (3), 141-149. Doi : 10.20883/jms.367 ABSTRACT Cannabinoids from Cannabis sativa L. play an important role as natural products in clinics. The major cannabinoids compromise tetrahydrocannabinolic acid (THCA) and cannabidiolic acid (CBDA) and its decarboxylated analogs. In this review, we focus on often neglected minor cannabinoids and discuss biosynthetic and chemical degradation routes to other neglected cannabinoids in Cannabis sativa starting from THCA, CBDA and cannabichromenic acid (CBCA). Based on the literature, patents and scientific reports, essential routes for the chemical modifi cation of cannabinoids are discussed to explain [...]

Ayahuasca : Uses, Phytochemical and Biological Activities Edgar Antonio Estrella‑Parra · Julio Cesar Almanza‑Pérez · Francisco Javier Alarcón‑Aguilar Natural Products and Bioprospecting, 2019, 9, 251–265 doi : 10.1007/s13659-019-0210-5 Abstract Ayahuasca (caapi, yajé), is a psychoactive brew from the Amazon Basin region of South America traditionally considered a “master plant.” It is prepared as a decoction from Banisteriopsis caapi and Psychotria viridis, which it is thought that it stimulates creative thinking and visual creativity. Native healers of the Orinoco and Amazon basins have used traditionally ayahuasca as a healing tool for multiple purposes, particularly to treat psychological disorders in the patients, with some beneficial effects experimentally [...]
Lire la suiteRole of the endogenous cannabinoid system in nicotine addiction : novel insights Islam Hany Gamaleddin, Jose M.Trigo, Aliou B. Gueye, Alexander Zvonok, Alexandros Makriyannis, Steven R. Goldberg and Bernard Le Foll Frontiers in Psychiatry, 2015, Vol 6, Article 41, 1-12. doi : 10.3389/fpsyt.2015.00041 Several lines of evidence have shown that the endogenous cannabinoids are implicated in several neuropsychiatric diseases. Notably, preclinical and human clinical studies have shown a pivotal role of the cannabinoid system in nicotine addiction. The CB1 receptor inverse agonist/antagonist rimonabant (also known as SR141716)was effective to decrease nicotine-taking and nicotine-seeking in rodents, as well as the elevation of dopamine induced by [...]

In the latest decades, an important milestone concerning the endocannabinoid system was the discovery of the existence of the cannabinoid receptors CB1 and CB2. Anandamide was the first reported endogenous metabolite, which adjusted the release of some neurotransmitters through binding to the CB1 or CB2 receptors. Then a series of cannabinomimetric lipids were extracted from marine organisms, which [...]
