Lire la suiteCannabis and Depression Daniel Feingold, Aviv Weinstein Advances in Experimental medicine and Biology, 2021, 1264, 67-80. In book : "Cannabinoids and Neuropsychiatric Disorders", Aviv Weinstein 's Lab Doi : 10.1007/978-3-030-57369-0_5 Abstract There is a growing body of evidence pointing to the co-occurrence of cannabis use and depression. There is also some evidence that the use of cannabis may lead to the onset of depression; however, strong evidence points to the inverse association; i.e. that depression may lead to the onset or increase in cannabis use frequency. Observational and epidemiological studies have not indicated a positive long-term effect of cannabis use on the course and outcome of [...]
Lire la suiteTHREE NEW STUDIES ON CANNABIS AND PTSD Growing numbers of trauma sufferers are medicating with cannabis and finding it helpful. NATE SELTENRICH 31 décembre 2022 In recent years, psilocybin and MDMA have been explored as potential treatments for post-traumatic stress disorder, but somewhat more quietly so has cannabis. In fact, according to a few quick searches of PubMed, cannabis has a longer and richer association with PTSD in the scientific literature than any psychedelic. Though you wouldn’t know that by reading the headlines. Setting aside for a minute how effective psychedelics may or may not be as breakthrough treatments for PTSD, there’s no doubt that [...]

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 [...]
