The oldest collection of marijuana was found in a tomb in China. According to the Journal of Experimental Botany, cannabis is about 2,700 years old.
The researchers found 789 grams of marijuana buried in what I assume to be the grave of a shaman of the Gushi culture. It was found in Turpan, in northeastern China. The fact that the "bounty" was dry and alkaline soil preserved it, which allowed the scientists studied.
According to our knowledge, these investigations provide the oldest documentation of cannabis as a pharmacologically active agent, said neurologist Ethan B. Russo. However, the researchers could not determine whether the marijuana they found was ingested or smoked. We found no clue to reach a conclusion.
It was speculated that the drug could have been collected accumulated for use in the afterlife. "It was common practice in burials to provide materials needed for life in the other world," said Russo.
