Clinical verdict
Ayahuasca = DMT (Schedule I) + MAO inhibitors. The MAOI component creates LETHAL serotonin syndrome risk with SSRIs/SNRIs. DEATHS at ayahuasca retreats — often from SSRI interactions the ceremony leaders don't screen for. Anyone on serotonergic medication + ayahuasca = potential death. 'Plant medicine' products containing harmine/harmaline carry same MAOI danger [1].
