ALBANY, N.Y., Jan. 12 (UPI) -- U.S. archaeologists examining Mayan containers say they've identified nicotine traces in a flask, the first physical evidence of tobacco use by ancient Mayans.
The study published in Rapid Communications in Mass Spectrometry said the residue was identified in a flask marked with Mayan hieroglyphics reading, "y-otoot 'u-may," ("the home of its/his/her tobacco.")
