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 tobacco smoking 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 中国“能源金三角”萧条：房地产大量折价倾销.

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 Pacific Northwest 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.

Belgium, for example, has less than a tenth of the population of Russia, its rival in the group stage, but is regarded as a far greater threat. And then there is Uruguay, which despite fewer than 4 million citizens -- barely a sixth of the population of greater S?o Paulo -- is one of the teams Brazil would least like to meet on its way to the final. How is this so?
