The growth of a pre-Inca civilization known as the Wari may have been aided by psychedelic-laced beer, researchers propose in a new study.
The Wari flourished from roughly A.D. 600 to 1000 and are known for their mummified burials, human sacrifices, and elaborate objects created out of gold, silver and bronze. They also built cities such as Huari and Pikillaqta, which contained temples and dwellings for elite inhabitants, and controlled much of Peru as well as parts of Argentina and Chile.
