O’Keane Irish Journal of Psychological Medicine, 2020, 1-6. doi:10.1017/ipm.2020.94 The medium- to long-term consequences of COVID-19 are not yet known, though an increase in mental health problems are pre- dicted. Multidisciplinary strategies across socio-economic and psychological levels may be needed to mitigate the mental health burden of COVID-19. Preliminary evidence from the rapidly progressing field of psychedelic science shows that psilocybin therapy offers a promising transdiagnostic treatment strategy for a range of disorders with restricted and maladaptive habitual patterns of cognition [...]

Doi : 10.1016/j.cell.2020.03.020 After a legally mandated, decades-long global arrest of research on psychedelic drugs, investiga- tion of psychedelics in the context of psychiatric disorders is yielding exciting results. Outcomes of neuroscience and clinical research into 5-Hydroxytryptamine 2A (5-HT2A) receptor agonists, such as psilocybin, show promise for addressing a range of serious disorders, including depression and addiction. Introduction—Why the Psychedelic Revolution in Psychiatry? Research leading to the discovery of new pharmacological treatments for psychiat- ric disorders has been painfully slow. With a few exceptions, including the use of orexin [...]

More recently, emerging evidence has pointed out the potential therapeutic properties of psilocybin and LSD, as well as [...]

Abstract and Introduction Introduction Against the backdrop of an increasing opioid use epidemic and a marked acceleration of prescription opioid–related deaths,[1,2] there has been an impetus to explore the usefulness of alternative and co-analgesic agents to assist patients with chronic pain. Preclinical studies employing animal-based models of human pain syndromes have demonstrated that cannabis and chemicals derived from cannabis extracts may mitigate several pain conditions.[3] Because there are significant comorbidities between psychiatric disorders and chronic pain, psychiatrists are likely to care for patients with chronic pain. As [...]

In a trial with a crossover design, investigators randomly assigned 28 patients with severe TRMD to receive a single 1-hour inhalation of placebo or nitrous oxide once a month over a 3-month period. Participants received an inhalation of placebo; a 25% concentration of nitrous oxide; and a 50% concentration of nitrous oxide. Sessions were [...]

Doi : 10.14740/jocmr4159 Abstract Cannabidiol (CBD) is a substance chemically derived from Cannabis sativa and discussed to be non-psychoactive.

Pour ses vertus thérapeutiques, mais aussi festives et sacrées. Avec lui, nous découvrons aussi que la prohibition du cannabis est née aux USA, sur des préjugés racistes. Celui que nous allons rencontrer aujourd’hui, dans les premières collines, au sud du Massif Central, est un des psychiatres français les plus connus et les plus engagés dans la recherche [...]
