Ancient Siberian tomb reveals earliest cannabis use
リーディング
A new study suggests people used cannabis a very long time ago. This was perhaps 2,800 years in the past.
Scientists found this new information in a big old tomb in Siberia. They think people used cannabis there to change how they felt.
This means people used cannabis 300 years earlier than we knew before. Many researchers find old drug use very interesting.
The team found cannabis seeds and human hair in the tomb. This helps us understand the plant's part in old societies.
However, some experts do not agree with the study's ideas. They say the hair tests do not clearly show cannabis was used by people.
