# Incan Children Administered Hallucinogens Before Ritual Sacrifices New toxicology tests reveal children were given cocaine, alcohol, and ayahuasca-related substances. - **Source:** [Scientific American Content: Global](https://brifing.si/source/4f066134-e06d-4415-87ef-305e3dc2aba6) - **Published:** 2026-11-03 - **Topic:** [Business](https://brifing.si/c/business) - **Original article:** - **On Brifing:** https://brifing.si/s/7befb21b-84a2-4456-a545-955d803f1d77 ## Advanced Toxicology Reveals Ritual Practices Recent toxicological studies published in Antiquity provide new insights into Incan capacocha rituals. Researchers analyzed hair and nail samples from eight mummified bodies found near sacrificial sites in Peru and Argentina. These findings move beyond previous inconclusive data, identifying specific psychoactive substances administered to children before they were sacrificed to deities. ## Cocaine Use and Altitude Adaptation All eight examined bodies contained traces of cocaine and its metabolite, benzoylecgonine. Archaeologists suggest these substances were likely administered to help children manage severe altitude sickness and physical fatigue during their arduous mountain climbs. This pharmacological intervention highlights the practical considerations integrated into the religious preparations for these high-altitude sacrificial ceremonies. ## Alcohol Consumption in Final Rites Four of the mummified remains tested positive for alcohol, likely derived from chicha, a traditional maize-based beer. Historical records indicate that this beverage served a specific purpose during the final stages of the ritual. It was intended to calm the children, ensuring a more peaceful transition during the concluding moments of the ceremony. ## Ayahuasca Components in Sacred Ceremonies Three bodies contained harmine and harmaline, alkaloids found in the hallucinogen ayahuasca. Specifically, the presence of harmine suggests the use of Banisteriopsis species in beverages. Researchers believe this indicates that certain sacred mountains or specific cults utilized unique psychoactive mixtures, reflecting a complex and non-uniform approach to the broader Incan religious traditions. ## Geographic and Ritual Variability The study demonstrates that the capacocha ceremony was not a standardized, singular event across the Incan Empire. Instead, the variation in substances found across different sites suggests that rituals were adapted to local religious traditions and specific cults. This diversity reveals a sophisticated, localized approach to venerating gods throughout the vast territory. ## Technological Advances in Archaeological Science Modern toxicology now allows for the detection of extremely low concentrations of psychoactive substances in ancient biological samples. These technological leaps enable researchers to reconstruct historical practices with unprecedented precision. By identifying these chemical markers, scientists can now map how ancient civilizations interacted with their environment and managed complex ritualistic social structures. ## Context of the Incan Empire Spanning from the 13th to the 16th centuries, the Incan Empire utilized these sacrifices to restore stability during crises like droughts or famines. Children acted as messengers between the living and the deities. These rituals were conducted at temples, oracles, or high-altitude sites, often involving extensive travel to the capital, Cusco. ## Future Implications for Historical Research While current technology has identified several substances, researchers acknowledge that other undetectable compounds may have been used. This study underscores that Incan religious life was deeply intertwined with botanical knowledge and pharmacological application. Future research will likely continue to refine our understanding of how these ancient peoples honored their gods through ritual. ## Sources covering this story - https://www.scientificamerican.com/article/incan-children-were-given-hallucinogens-before-they-were-sacrificed-to-the-gods/ — --- _Summary written by Brifing from the original reporting.
