In the specific case of Ayahuasca, its current media presence and the West’s interest in these practices has opened up a major political and legal debate. Thus, while the millennial experience of indigenous peoples and scientific studies show that ritualized and respectful use of tradition does not create health risks, the fact that DMT is contained, a substance classified as “drug without medical use” by the Vienna Convention, determines that its use is prescribed. While WHO encourages the recovery and study of traditional medicines, the IFJ recommends that countries monitor and restrict the use of traditional psychotropic plants, ayahuasca, peyote, iboga, among others, monitor them and, as far as possible, prevent their traffic or exit, for “causing adverse effects such as nausea, vomiting, weakness, poisoning and flashbacks, with serious consequences on welfare…” (June 2011). This shows the disengagement between customary law of native populations and laws and norms that are inadequate and obsolete because they are marked by prejudice or commercial interest in mega-projects.
