Ancient Siberian tomb yields earliest cannabis use evidence

A recent study posits that humans may have used cannabis for its psychoactive properties far earlier than previously assumed. Archaeological findings from a Siberian tomb suggest this practice dates back at least 2,800 years, significantly predating earlier estimates.

This discovery pushes back the known timeline for cannabis consumption by centuries, particularly in comparison to neighbouring regions like China. It also lends credence to ancient historical accounts, such as those by Herodotus, describing Central Asian inhabitants smoking the plant.

Researchers conducted detailed analysis of human hair recovered from a royal tomb, where cannabis seeds were also unearthed. This rare confluence of preserved plant material and human soft tissue containing active compounds provides compelling contextual evidence.

The excavation took place at Tunnug 1, a monumental burial mound in Siberia's Uyuk Valley, associated with ancient Scythian nomads. Alongside weaponry and horse gear, archaeologists "struck gold" by finding tiny cannabis seeds and preserved human hair within the burials.

Not all independent experts are convinced by the study’s assertions, citing concerns over the scientific robustness of the hair analysis. Critics argue that the data might not definitively distinguish between actual consumption and mere external exposure, requiring further forensic validation.
