Aztec Use of Entheogens - Picietl

Tobacco (Nicotiana tabacum), or picietl in nahuatl, was also used among the Aztecs. This plant was identified on the Xochipilli statue as well as on other items such as snuff boxes. The Aztec smoked and chewed tobacco, and possibly drank infusions of the plant to induce visions. Certain rites and ceremonies required the use of tobacco. One dedicated to Tlaloc involves chewing tobacco to enter an altered state:

In another ritual a priest would climb a mountain naked and painted black, carrying fir boughs and a conch trumpet. He would chew tobacco and periodically blow the horn. After piercing his ears and thighs with spines to let blood, he would retrace his steps stumbling.
