The first pothead lit up way before 420 BC

To the list of things that Chinese people did first (detonated fireworks, navigated with a compass, traded with paper money, and printed books), add "smoked pot."

A marijuana stash was discovered in a 2,700-old Chinese tomb. Well, OK, he was a white Chinese guy and he probably would've claimed that he was just holding it for a friend, but it still counts.

The full academic yatter is in the Journal of Experimental Botany. I wonder how grad students who submit articles to the journal "test" experimental botany. Newspapers also reported the archeological find.
