In Action

Psilocybin starts working in as little as 2 minutes when injected and 30–60 minutes when taken orally, peaking around the 2-hour mark. It’s quickly converted into psilocin, which crosses the blood–brain barrier and drives its effects. Most is cleared from the body within 6 hours, making psilocybin one of the shortest-acting classic psychedelics.
