Study: Single dose of psilocybin provided rapid relief from depression

Conducted by researchers at Karolinska Institutet, the study involved 35 participants and showed significant improvement in depressive symptoms compared to a placebo. While the treatment was generally well tolerated, the long-term effects and need for repeated treatments remain uncertain.
