While excavating in a dry cave near the Sora River valley in southwestern Bolivia, archaeologists from the University of Otago and the University of California - Berkeley unexpectedly found a strange and mysterious ancient ritual artifact.

It was a leather bag containing a bundle of psychoactive herbs, two crushed and rolled up inhaler pills made from the psychoactive herbs, and an inhaler for inhaling the psychoactive substances.

Using accelerator mass spectrometry and radiocarbon dating, experts determined that this leather bag is 1,000 years old and belongs to Native Americans in South America.

To better understand, the team used a scalpel to take small samples from inside the leather bag and analyzed them using liquid chromatography coupled with tandem mass spectrometry.

The results show that the researchers identified the presence of several psychoactive compounds — cocaine, benzoylecgonine (the main metabolite of cocaine), harmine, bufotenin, dimethyltryptamine (DMT), and psilocin from at least three different plant species (possibly Erythroxylum coca, Anadenanthera, and Banistesteriopsis caani).

According to Jose Capriles, associate professor of anthropology at the University of California - Berkeley, about 1,000 years ago, Native Americans in South America used a variety of psychoactive plants - possibly using them at the same time - to induce hallucinations and alter perceptions.

“We knew that psychoactive substances played an important role in the spiritual and religious practices of ancient societies in the south-central Andes, but we did not know that ancient people used so many different psychoactive compounds and could combine them together,” said Jose Capriles. “This is the largest number of psychoactive substances ever found in an archaeological discovery in South America.” Photo: @University of California - Berkeley.
