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 家居装饰展会主打色彩营销.
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 tobacco 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 nicotine addiction 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.

Ah yes, the other reason Sacramento shouldn't tank: Philadelphia has the option to swap picks with them this year. It's actually impossible for the Kings to get the No. 1 pick because of that, and it hurts their chances at a top-three pick overall.

Hailed as one of the greatest films of all time, Taxi Driver tells the story of a depressed ex-Marine who attempts to assassinate a senator after being rejected by a woman he admires. While the titular taxi driver, Travis Bickle, lives a chaotic life filled with drug dealers and prostitutes, his story was never meant to be an unrealistic fantasy.
