The Lancet Psychiatry – one of the world's most highly respected journals – report today that a single dose of psilocybin ('magic mushrooms') relieved depression in all 12 subjects in a clinical study. All the subjects belonged to the ~20% of depression sufferers who get no benefit from standard anti-depressants. Eight of them came completely out of depression, and 5 of these were still cured at the end of the study (see the graph). !science !fediverse
