New findings confirm the use of psychoactive plants and ritual music to reinforce hierarchical social structures 2,000 years before the Inca.

The site of Chavin de Huantar in modern-day Peru hosts several monumental buildings overseeing a large plaza, located at an elevation of 10,000 ft.

Overview

  • Chemical analyses of bone snuff tubes at Chavín de Huántar revealed residues of wild tobacco and vilca beans, a DMT-related hallucinogen.
  • These psychoactive rituals were restricted to elite participants in private chambers, emphasizing exclusivity and control over mystical experiences.
  • Archaeologists uncovered conch shell trumpets and acoustically designed chambers, indicating that music played a central role in these ceremonies.
  • The rituals, combining hallucinogens and music, reinforced social hierarchies by linking leadership to supernatural power and ideology.
  • Published in the Proceedings of the National Academy of Sciences, the study sheds light on how Chavín culture used immersive rituals to naturalize inequality.
