Group psilocybin therapy is feasible for low-income adults with depression in Oregon's regulated psilocybin program. In an open-label study, 20 participants began treatment and 19 completed two psilocybin administration sessions one week apart, with preparation and integration sessions online. No severe adverse events occurred; participants rated satisfaction 4.8 out of 5, reporting moderate to high benefit and no harm. Exploratory outcomes showed a significant decrease in Hamilton Depression scores with a strong effect size (Cohen's d = 1.89), and all eight domains of the PROMIS-29 significantly improved with effect sizes from 0.667 to 1.774. Further research with comparator groups is warranted.
