In terms of drug interaction risk, psilocybin has the narrower danger profile. Ayahuasca’s MAOI content creates severe, potentially life-threatening interactions with SSRIs, SNRIs, tyramine-rich foods, and several other medications (Edinoff et al., 2022; Callahan et al., 2018). Psilocybin does not carry the same MAOI risk. That said, neither is safe in an absolute sense, both carry psychological risk for individuals with personal or family histories of psychosis or schizophrenia. The safest version of either experience is one with proper health screening and qualified support.
