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 marijuana stash, according to a paper in the latest issue of the Journal of Experimental Botany.
A barrage of tests proves the marijuanapossessed potent psychoactive properties and casts doubt on the theory that the ancients only grew the plant for hemp in order to make clothing, rope and other objects.

They apparently were getting high too.
Lead author Ethan Russo told Discovery News that the marijuana "is quite similar" to what's grown today.
"We know from both the chemical analysis and genetics that it could produce THC (tetrahydrocannabinolic acid synthase, the main psychoactive chemical in the plant)," he explained, adding that no one could feel its effects today, due to decomposition over the millennia.
The size of seeds mixed in with the leaves, along with their color and other characteristics, indicate the marijuana came from a cultivated strain. Before the burial, someone had carefully picked out all of the male plant parts, which are less psychoactive, so Russo and his team believe there is little doubt as to why the cannabis was grown.
What is in question, however, is how the marijuana was administered, since no pipes or other objects associated with smoking were found in the grave.
"Perhaps it was ingested orally," Russo said. "It might also have been fumigated, as the Scythian tribes to the north did subsequently."
