Scientists have identified the presence of a non-tobacco plant in ancient Maya drug containers for the first time.
Originally buried more than 1,000 years ago on Mexico’s Yucatán peninsula, the vessels also contain chemical traces present in two types of dried and cured tobacco, Nicotiana tabacum and N. rustica. The research team, led by anthropology postdoc Mario Zimmermann, thinks the Mexican marigold was mixed with the tobacco to make smoking more enjoyable.
“While it has been established that tobacco was commonly used throughout the Americas before and after contact, evidence of other plants used for medicinal or religious purposes has remained largely unexplored,” Zimmermann said. “The analysis methods developed in collaboration between the Department of Anthropology and the Institute of Biological Chemistry give us the ability to investigate drug use in the ancient world like never before.”
