The oldest stash of cannabis is 2,700 years old and was found in a remote tomb in China. Scientists are reported to be running a series of tests on the 789 grams of the dried marijuana found.
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 marijuana possessed 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.
