What traditional snuff from South America often contains DMT or related tryptamines?

Yopo (or Cohoba) is a traditional hallucinogenic snuff prepared from the seeds of the South American and Caribbean tree Anadenanthera peregrina (and closely related species). It was used for centuries—possibly millennia—by Indigenous peoples of the Orinoco basin, the Caribbean Taíno, and other groups in ritual, divinatory, and ceremonial contexts. Early European accounts, including those linked to Columbus’s voyages, describe its use. The seeds contain psychoactive tryptamines, principally bufotenine (5-HO-DMT), along with smaller amounts of DMT and 5-MeO-DMT, which produce intense, short-lasting visionary effects when insufflated.
