Psilocybin degrades quickly into its active metabolite psilocin after ingestion. Both psilocin and psilocybin exhibit affinity for a range of serotonin receptors (5-HT1A/B/D/E, 2B, 5, 6, 7) with high affinity for the 5-HT2A receptor. | Psilocybin degrades quickly into its active metabolite psilocin after ingestion.
