In addition, 71% showed improvement at 4-week follow-up, with more than 50% achieving remission. "The finding that the majority of people whom we treated showed efficacy was quite a remarkable and gratifying finding [...]

Psilocybin Matches SSRI for Moderate-to-Severe Depression in Phase 2 Study, Sarah Edmonds, 2021

Psilocybin Matches SSRI for Moderate-to-Severe Depression in Phase 2 Study Sarah Edmonds Medscape Medical News, April 14, 2021   The psychedelic drug psilocybin performed just as well as a widely used antidepressant in easing the symptoms of major depression, and outperformed the selective serotonin reuptake inhibitor (SSRI) on a range of secondary measures, results of a small-scale phase 2 study show. In a 6-week trial that included 59 patients with moderate-to-severe depression, there was no significant difference between the impact of high-dose psilocybin on the study's primary yardstick — the 16-item Quick Inventory of Depressive Symptomatology–Self-Report (QIDS-SR-16) — and that of selective serotonin reuptake [...]

Clinical Evidence of Magistral Preparations Based on Medicinal Cannabis, Sara Arias et al., 2021

Clinical Evidence of Magistral Preparations Based on Medicinal Cannabis Sara Arias, Marta Leon, Diego Jaimes and Rosa-Helena Bustos Pharmaceuticals, 2021, 14, 78, 1-13. Doi :10.3390/ph14020078   Abstract : Cannabis has been widely used as a medicinal plant for millennia; however, studies related to its main components were first conducted in 1960. Subsequently, laboratories have produced new components and structures related to its active biological properties. Countries that have approved the medicinal use of cannabis impose regulations that govern its clinical and scientific use. One means of administering medicinal cannabis is via a magistral preparation that must have a medical prescription and be prepared in an establishment [...]
