Editing Coca (section)

===Coca use in labor and military service===
One of the most common uses of coca during the reign of the Inca was in the context of ''[[mit'a]]'' labor, a labor tax required of all able-bodied men in the Inca empire, and also in military service. [[Pedro Cieza de León]] wrote that the indigenous people of the Andes always seemed to have coca in their mouths. ''Mit'a'' laborers, soldiers, and others chewed coca to alleviate hunger and thirst while they were working and fighting. The results of this are evident in monumental construction and the successful expansion of the Inca empire through conquest. By chewing coca, laborers and soldiers were able to work harder and for longer periods. Some historians believe that coca and ''chicha'' (fermented corn beer) made it possible for the Incas to move large stones in order to create architectural masterpieces, especially ones of [[monolith]]ic construction such as [[Sacsayhuamán]].<ref name="auto"/>
