Psilocybin is metabolized within hours, but its effects on the brain last weeks to months.

How Long Does Psilocybin Stay in Your System?

Direct Answer: Psilocybin is metabolized within 24 hours. Standard drug tests do not test for psilocybin. However, the neurological effects can persist for weeks to months.

Psilocybin Pharmacokinetics

Onset: 20–60 minutes. Peak effects: 60–90 minutes. Duration: 4–6 hours. Half-life of psilocin: ~50 minutes. Complete clearance: within 24 hours. Standard 5-panel and 10-panel drug tests do not include psilocybin.

The Lasting Effects Paradox

Psilocin is gone within 24 hours, yet antidepressant effects can last months. This is explained by the neuroplasticity mechanism — psilocybin triggers lasting structural changes to the brain that persist long after the drug is cleared.
