# Ancient Cannabis Use Discovered in 2,800-Year-Old Siberian Grave Chemical analysis of hair samples reveals the earliest evidence of psychoactive cannabis consumption. - **Source:** [Aftonbladet](https://www.aftonbladet.se) - **Published:** 2026-11-09 - **Topic:** [science](https://brifing.si/c/science) - **Original article:** - **On Brifing:** https://brifing.si/s/989fec80-1899-4ffc-ad55-a8fa7f5985a7 ## Discovery in Siberian Grave Archaeologists identified traces of cannabis in the hair of a young girl, aged 15 to 18, buried in southern Siberia approximately 2,800 years ago. The remains belong to a Scythian nomadic group. This discovery provides a rare, tangible link to the ancient use of psychoactive substances in prehistoric burial rituals. ## Evidence of THC Consumption Scientific analysis confirmed the presence of THC, the primary psychoactive component of cannabis, within the girl's well-preserved hair samples. This finding, published in the journal Science, marks the oldest known evidence of humans using cannabis for its intoxicating effects rather than solely for industrial purposes like textiles or food production. ## Ritualistic Burial Context The grave contained significant quantities of cannabis seeds alongside evidence of both human and horse sacrifices. Researchers suggest these elements indicate that the drug played a specific role in funerary rites. The presence of these items implies the deceased held a status of importance within her nomadic social structure. ## Shifting Historical Perspectives While historical records confirm that ancient cultures cultivated hemp for oil, fibers, and rope, archaeological proof of recreational or ritualistic consumption has been scarce. Natalia Riabogina from the University of Gothenburg notes that this discovery fills a critical gap in our understanding of how early societies interacted with psychoactive plants. ## Scythian Nomadic Culture The Scythians were nomadic tribes known for their mobility and complex social hierarchies across the Eurasian steppe. Their burial mounds, or kurgans, often contain elaborate grave goods. This specific site highlights the integration of botanical knowledge and spiritual practices, reflecting a sophisticated cultural approach to death and the afterlife. ## Methodology of Analysis The identification of THC was made possible through advanced chemical analysis of the girl's hair, which remained well-preserved over nearly three millennia. By isolating specific chemical markers, researchers could confirm the ingestion of the substance. This technique demonstrates how modern forensic science can extract detailed behavioral data from ancient biological remains. ## Broader Archaeological Implications This finding challenges previous assumptions regarding the timeline of human drug use. It suggests that the intentional use of cannabis for its mind-altering properties was already established among nomadic populations in Siberia by the 8th century BCE. This adds a new layer to the study of ancient human-plant interactions globally. ## Future Research Directions The discovery prompts further investigation into other burial sites across the region to determine if cannabis use was widespread or limited to specific elite groups. Understanding the prevalence of these rituals will help historians map the cultural diffusion of plant-based substances throughout ancient nomadic trade routes and social networks. ## Sources covering this story - https://www.aftonbladet.se/nyheter/a/0vEy4B/spar-av-cannabis-hittat-i-tretusenarig-grav?utm_medium=rss — --- _Summary written by Brifing from the original reporting.
