As Peru's Wari kingdom sought to shore up their crumbling empire over 1,000 years ago they did it with their own form of bread and circuses - cocaine, ayahuasca, and
a beer with psychedelics mixed in.

It obviously didn't work forever, the Incas conquered them, but the archaeological evidence provides a compelling look into South American culture of 1000 AD.
