Oldest direct evidence of psychoactive cannabis use found in 2,800-year-old Siberian tomb

A study published in Science reports the oldest direct evidence of psychoactive cannabis consumption, from the Tunnug 1 burial in Siberia's Uyuk River Valley, dated to the 8th century BCE. Cannabinoids including THC were detected in preserved hair, alongside more than 1,400 cannabis seeds around the remains. The team, led by Gino Caspari, plans DNA analysis of the seeds to study domestication history. No defensive or security action is relevant.
