What was claimed

America's First Legal Psilocybin Program Treated 346 People. Just one month after the dose, 92.2 percent of participants said the experience had been beneficial, while, on average, their mental health symptoms had fallen dramatically.

Our verdict

Accurate

Multiple reports on Oregon’s state‑regulated psilocybin services describe a federally funded cohort study that followed 346 adults receiving psilocybin at licensed centers between late 2024 and 2026. These sources characterize this as the first legal statewide psilocybin program in the U.S., so the participant number and description are accurate.
