Tooth tartar could uncover the drug habits of ancient people
Jan. 7, 2021 , 3:25 PM
Want to know whether an ancient Sogdian smoked cannabis or a Viking got high on henbane? A new method, which analyzes drug residue in the tartar of teeth, may soon be able to tell. The method, which found drug traces on 19th century skeletons and more substances than standard blood tests in 10 recently deceased individuals could trace humanity’s drug habits back hundreds of thousands of years. It’s a “new frontier,” says archaeologist Shannon Tushingham of Washington State University, Pullman, who investigates ancient tobacco use in North America, but was not involved in the new work.
