Comprehensive comparison
Psilocybin
Often within about 1–7 days after a supported dose.34
Ayahuasca
In the key small study, benefits showed by day 1 and were clearer by day 7.1
Psilocybin
Trials commonly follow people across months after one or two dosing days.34
Ayahuasca
Controlled follow-up in the pivotal study was short; longer reports are mostly open-label or observational.129
Psilocybin
Nothing to taper. Integration is the ongoing work.
Ayahuasca
Nothing daily to stop after a ceremony course — though retreats are often repeated by choice.
Psilocybin
1–2 supported dosing days plus prep and integration.34
Ayahuasca
Hospital studies often used one dose; commercial retreats often run 3–4 ceremonies in a week.128
Psilocybin
Legal Oregon and Colorado guided programs typically run about $850–$4,500+ self-pay.7
Ayahuasca
Peru retreat weeks often about $850–$2,400; Costa Rica is often higher.8
Psilocybin
Almost never. State-legal guided sessions are typically self-pay.7

Psilocybin
Several carefully controlled studies in depression; not FDA-approved.345
Ayahuasca
One small carefully controlled study plus early research — promising, but samples are small.129
