Scientists have discovered two pounds of a dried plant that turned out to be the oldest marijuana in the world. Inside one of the Yanghai Tombs excavated in the Gobi Desert
At first, the researchers thought the dried weed was coriander. Then they spent 10 months getting the cannabis from the tomb in China to a secret lab in England. Finally, the team put the stash through “microscopic botanical analysis” including carbon dating and genetic analysis, and discovered the stash was really pot.
The fact that the weed had a chemical known for psychoactive properties called tetrahydrocannabinolic acid synthase, or THC, led scientists to believe the
community probably used it for medicinal and recreational purposes. According to professor Ethan Russo of the Chinese Academy of Sciences Institute of Botany, someone had picked out all the parts of the plant that are less psychoactive before placing it in the grave, therefore the dead man probably didn’t grow his hemp merely to make clothes.
