I once asked don Rómulo Magin about his awareness of the spirits when not drinking ayahuasca. Don Rómulo said that he is constantly aware of being surrounded by the spirits, but he sees them roughly, vaguely; drinking ayahuasca, he said, is “like putting on glasses.” Doña María Tuesta agrees; ayahuasca makes the spirits bien claro, really clear.
After many years of effort, psychopharmacologist Rick Strassman finally got permission to administer DMT to human volunteers in a hospital setting. Out of this research came a steady stream of scientific articles and, eventually, a popular book, DMT: The Spirit Molecule. But the study ended in what can only be described as chaos and confusion, and it may be worth thinking about why that happened.
Mapacho, the tobacco ingested by shamans in the Amazon, is a species containing very high levels of nicotine and other psychoactive pyridine alkaloids — indeed, the highest nicotine levels of any tobacco species; leaves from this species contain more than eight percent nicotine, as much as twenty-six times the amount found in the common cigarette tobacco in North America. There is also reason to believe that psychoactive alkaloids other than nicotine are present in noncommercial varieties of tobacco.
Indigenous Amazonian peoples ingest tobacco in every conceivable way — smoked, as a snuff, chewed, licked, as a syrup applied to the gums, and in the form of an enema. Mestizo shamans consume tobacco as a cold-water infusion, in cigarettes, or in specially carved pipes; tobacco may also be added to the ayahuasca drink.
