UC Davis researchers uncover earliest tobacco use in the Pacific Northwest

(Phys.org)—Native American hunter-gatherers living more than a thousand years ago in what is now northwestern California ate salmon, acorns and other foods, and now we know they also smoked tobacco—the earliest known usage in the Pacific Northwest, according to a new University of California, Davis, study.

"The study demonstrates that was part of the northwestern California culture very early ... shortly after the earliest documented Pacific Northwest Coast plank house villages," said the study, published in the .

Testing organic residues extracted from pipes, researchers from the UC Davis Department of Anthropology and the Fiehn Metabolomics Laboratory of the UC Davis Genome Center confirmed was smoked, and likely grown in the region, by at least A.D. 860.

Perhaps more importantly, the researchers say that additional studies may help them better understand the origins of and the human management, geographic range extension and cultivation of tobacco. Indeed, as part of a second study, the authors have recently detected nicotine in ancient pipes from an 800-year-old site in the modern city of Pleasanton, Calif.

The house is on a slight hill above the street. Its entry is a large glassed porch with a brick floor and walls of windows facing the lake.

The Gwen Stefani campaign ran on several apps, including Tango, the Silicon Valley-based messaging app. Tango earns money on ads within a user’s inbox, but it has adopted Swyft’s platform because the ads are in line with the way people already use Tango, says Richard Rabbat, vice president of Advertising and Platform at Tango. A year ago, Tango decided not to sell stickers, because asking users for money creates too much friction, he says. “Putting a payment gate in the way of communication is not the right experience we want to give to our users,” Rabbat says. Ergo, ad campaigns from Swyft.

Prior to this recent testing, which used sensitive gas chromatography/mass spectrometry, researchers were unsure of the historical use of tobacco on the Coast. It was unclear, for example, whether European traders had brought tobacco to the area much later, or if some other plant had been smoked in the pipes, Tushingham said.

The Warriors are one of the best teams in NBA history, and you can put their championship run up against any team in NBA history for the best playoff performance ever. But there's also a legitimate question of what this means for the sport. If the best or second-best player of all time stands no chance against this team, what does it mean for the sport's competitiveness? It hasn't been a problem so far, thanks to an extremely wild offseason, but the question remains: what happens to a competitive sports league when it's not truly competitive at the highest level?
