In a subject field publish Monday ( May 5 ) in the journalPNAS , Contreras and a squad of archaeologists analyzed the chemical residuum in 23 bone and shell artifacts from the archeologic land site of Chavín de Huántar in the Union - central highland of Peru . They localize out to investigate a long - standing assumption that rituals at the site involve psychoactive substances .

This study is the first to show the specific drugs that were inhaled at Chavín , where ritual bodily process was mellow but there was picayune direct evidence of drug employment .

Chavín was a major center of ritual activity between 1200 B.C. and 400 B.C. , before the birth of theIncaempire . The coordination compound include stone bodily structure construct around unfastened plaza .

An analysis of the chemical remainder on the artefact revealed that six contained the constituent compounds nicotine , potential from tobacco , and dimethyltryptamine ( DMT ) , a naturally fall out hallucinogenic drug commonly found inayahuasca afternoon tea .

Further microbotanical analysis showed that four of the artifacts once take roots of wildNicotianaspecies and the DMT - containing ejaculate and leaves of vilca ( Anadenanthera colubrina ) , which were likely dry , toasted and ground up to produce a strong sniff .

" The tubes would have been used — we think — as inhalator , " Contreras say , " for taking the snuff through the olfactory organ . "

The bone snuff tubes , which may have been made from the wing of aperegrine falcon(Falco peregrinus ) , were also concentrated in restrict - access areas of Chavín , intimate that psychotropic nub use was controlled by select participant , the researcher notice in the subject field .

Because only a fistful of people could go in the modest gallery areas at Chavín , the researchers think drug use reenforce the social power structure , creating an elite class disjoined from the workers who work up Chavín ’s telling repository .

" One of the ways that inequality was justified or naturalise was through ideology — through the founding of impressive ceremonial experiences that made citizenry believe this whole project was a good estimate , " Contreras said in a statement .

Controlled access to ritual drug use also may help to explicate a major social transition in the ancient Andes — from more egalitarian societies to the more hierarchical Tiwanaku , Wari and Inca empires .

These results suggest that additional work is needed to fully understand the importance of psychoactive meaning in the ancient Andes , the researchers publish .
