The researchers identified the presence of multiple psychoactive compounds—cocaine, benzoylecgonine (the primary metabolite of cocaine), harmine, bufotenin, dimethyltryptamine (DMT) and possibly psilocin (a compound found in some mushrooms)—from at least three different plant species (likely Erythroxylum coca, a species of Anadenanthera and Banistesteriopsis caani). The results will appear during the week of May 6 in Proceedings of the National Academy of Sciences.
