Archaeological record testifies to wide-spread practice of coca-leaf chewing in Andean cultures

The presence of coca-leaf "quid" in the bulging cheek of the naturally mummified remains of a 36-year-old male from the Maitas Chiribaya culture in northern Chile and similar portrayals in ceramic figurines from Moche culture in Peru demonstrate wide-spread practice of coca-leaf chewing among Andean peoples long before the Inca period.
