How old is the oldest weed plant?

Nearly two pounds of still-green plant material found in a 2,700-year-old grave in the Gobi Desert has just been identified as the world's oldest stash of marijuana, according to an article published in the latest issue of the Journal of Experimental Botany. Cannabis, also known as hemp or marijuana, evolved about 28 million years ago in the eastern plateau of Tibet, according to a pollen study published in May.

Nearly two pounds of still-green plant material found in a 2,700-year-old grave in the Gobi Desert has just been identified as the world's oldest stash of marijuana, according to an article published in the latest issue of the Journal of Experimental Botany. Cannabis, also known as hemp or marijuana, evolved about 28 million years ago in the eastern plateau of Tibet, according to a pollen study published in May. A close relative of the common hop found in beer, the plant still grows wild throughout Central Asia. More than 4000 years ago, Chinese farmers started growing it for oil and fiber to make ropes, clothing and paper.

Scientists have discovered two pounds of a dry plant that turned out to be the oldest marijuana in the world. Inside one of the Yanghai tombs excavated in the Gobi Desert, a team of researchers found cannabis packed in a wooden bowl that rested inside a 2,700-year-old tomb. It was placed near the head of a 45-year-old shaman with blue eyes, among other objects such as bridles and a harp for use in the afterlife. Scientists determined that the remains of slightly “beaten” plant matter from 2,700 years ago were marijuana.

The marijuana buds were neatly packed in a leather basket next to the head of the tomb owner. Scientists described the mummified inhabitant as Caucasian with blue eyes. Most likely, he was a shaman or a healer of the time, and because of his appearance, he may have traveled quite a bit.
