Researchers uncover earliest tobacco use in the Pacific Northwest

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.

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.

With executive compensation in the U.S. rising and the income gap only getting bigger, it's refreshing to see a CEO who cares about more than his own paycheck. Lenovo(LNVGF) Chief Executive Yang Yuanqing announced in September for the second year in a row that he would share at least $3 million of his bonus with roughly 10,000 of his workers. The generous decision was a product of the personal computer maker's record sales that year. The average worker payout is equal to roughly a month's pay for the typical city worker in China, according to Bloomberg News.

Like any college kid, Evan Wray loved using the tiny pictograms known as emoji. But he hated that there was no emoji to express his Fighting Irish pride with fellow University of Notre Dame students. So, alongside co-founder Sean O’Brien, he built a modest business on that disconnect. TextPride, as it was called, licensed images from brands in the sports and entertainment world and sold them as sticker packs. Within a messaging app like Kik, users could buy a packet of stickers for Disney’s Frozen for $1.99, for example.
