# Inca Children Were Drugged Before Sacrificial Rituals Toxicological analysis reveals children were administered psychoactive substances before the Inca capacocha sacrificial ceremonies. - **Source:** [New Scientist](https://www.newscientist.com/) - **Published:** 2026-11-03 - **Topic:** [Business](https://brifing.si/c/business) - **Original article:** - **On Brifing:** https://brifing.si/s/de8faa7d-268c-44be-a71e-cb4c52527c4d ## Ritualistic Drug Administration Research indicates that children selected for Inca capacocha rituals were administered psychedelic and intoxicating substances. Scientists suggest these drugs served to mitigate the terror of imminent death or facilitate communication with deities. Dagmara Socha notes that while these ceremonies were considered prestigious, the experience remained inherently traumatic for the young victims involved. ## Historical Context of Capacocha The Inca Empire spanned 4000 kilometers along South America's west coast from the late 13th century until the 16th-century Spanish conquest. The capacocha ritual was performed to prevent famine, drought, and pestilence. Spanish friar Martín de Murúa documented these practices in 1590, highlighting the ceremony's role in maintaining societal and agricultural stability. ## Analysis of Mummified Remains Researchers examined eight frozen mummies, including seven girls, discovered between the 1920s and 1990s at high-altitude sites in Peru, Argentina, and Chile. These individuals, aged between 6 and 14, were likely killed via sharp weapons or burial. The study utilized hair and nail samples to identify the specific substances consumed before their deaths. ## Toxicological Findings Detected Toxicological screening identified cocaine in all hair samples, alongside markers of alcohol and coca leaf consumption in half of the subjects. Furthermore, researchers detected harmine, a hallucinogenic compound found in ayahuasca, within one nail sample. These chemical signatures provide direct evidence of the substances used to alter the children's states before sacrifice. ## Psychological Management Strategy The presence of harmine suggests that the Inca utilized its antidepressant properties to calm the children and maintain a positive mood during the process. This chemical intervention indicates a sophisticated, albeit grim, understanding of substance effects. The goal was likely to ensure the children remained compliant throughout the final stages of the ritual. ## Unique Chemical Signatures Each sacrifice exhibited a unique chemical signature preserved in the biological samples, implying that children were prepared differently. Researchers hypothesize these variations might have been intended to direct the sacrifice toward specific deities. This suggests the capacocha was not a uniform event but a highly customized process tailored to individual religious requirements. ## Complex Ritualistic Process The study reframes the capacocha as a complex, multi-stage process rather than a singular sacrificial act. It involved extensive preparations, long-distance travel, and distinct ritual practices. By analyzing these mummies, archaeologists are gaining a deeper understanding of how the Inca integrated pharmacological substances into their state-sponsored religious and political life. ## Scientific Implications of Study Published in the journal Antiquity, this research underscores the necessity of interdisciplinary approaches in archaeology. By combining historical accounts with modern toxicology, scientists can reconstruct ancient practices with greater precision. These findings highlight the intersection of religious ideology, state control, and the physical manipulation of human subjects in the Inca Empire. ## Sources covering this story - https://www.newscientist.com/article/2596878-inca-child-mummies-were-drugged-before-being-sacrificed/?utm_campaign=RSS|NSNS&utm_content=home&utm_medium=RSS&utm_source=NSNS — --- _Summary written by Brifing from the original reporting.
