Russian burial site reveals use of cannabis as intoxicant 2,800 yrs ago

A study found evidence that cannabis was used for its intoxicating effects around 2,800 years ago at an ancient burial site in Siberia, Russia. Researchers reported over 1,000 cannabis seeds and detected traces of cannabis compounds in preserved human hair. Radiocarbon dating placed seeds between 800 and 760 BCE and findings suggest it may have been used during funerary rituals.
