Researchers examining an ancient burial site in Siberia have uncovered approximately 1,000 cannabis seeds alongside chemical traces indicating the plant was utilized nearly three millennia ago for its psychoactive properties.

The archaeological discovery, dating back 2,800 years, was made within a sepulcher that also contained remnants of complex funerary rites and animal offerings. Specialists state this represents the earliest direct archaeological documentation of mind-altering cannabis consumption.

Additional information is anticipated as investigation into the site continues to unfold.
