World's oldest cannabis stash found

The world's oldest stash of cannabis has been uncovered in China.

789 grams of marijuana was found buried in the tomb of a shaman and was so well-preserved that it retained its green colour.

The drug is thought to be around 2,700 years old, with researchers warning that it should not be smoked due to its lack of odour.

An article in the Journal Of Experimental Botany revealed: "[It is] the oldest documentation of cannabis as a pharmacologically active agent."

Bridles, a harp and archery equipment were also found in the tomb.
