Oldest evidence of cannabis smoking found in ancient Chinese cemetery

The broken wooden braziers, unearthed from 2,500-year-old tombs in Western China, contained burned, blackened stones, and the interior of the wooden vessels also looked charred. To find out what had been burned in them, University of Chinese Academy of Sciences archaeologist Yemin Yang and his colleagues used gas chromatography/mass spectrometry to analyze small samples of the charred wood and the residue from the stones.

Their analysis turned up a chemical called cannabinol, or CBN—an unmistakable chemical signature of cannabis. Those ancient chemical traces offer an important clue in the history of human drug use and the domestic history of cannabis.

[...] Although cannabis has turned up at other sites, from Western China to the Altai Mountains in Siberia, archaeologists have never found such direct indications that ancient people were lighting it up. Elsewhere, cannabis plants buried with the dead may be a sign that people ate parts of the plant for a similar effect (although brownies wouldn't be invented for millennia). But without doing a similar chemical analysis on human remains from those graves, archaeologists can't say for sure. At other sites, like a burial in the Altai Mountains of Siberia where archaeologists found a small tent, a bowl, and a pouch of cannabis seeds, it's pretty reasonable to speculate that the cannabis involved may have been intended for use as a drug.

[...] The burned residue in the Jirzankou braziers provides the first direct evidence of people burning cannabis for its smoke, but it's also the first unambiguous indication of people using the plant specifically for its mind-altering effects. Yang and his colleagues' chemical analysis found that the cannabis plants burned at the cemetery had been very high in THC, which makes them different from domesticated hemp plants and from most of the wild cannabis that grows on hillsides from the Caucasus to Western China.

    Given that the oldest know paper is a Hemp based sample found in China dating to ~450 BCE, which would put it right about the time this tomb was sealed.

    Also the Chinese, and many other ancient cultures, have long histories of using natural herbs for medicinal uses. Hells, the drinking of Tea in China dates back to 2737 BCE.

    Cannabis, peyote, psilocybin (aka "magic muchrooms"), and many others have been a part of Human culture since long before they had anything that would be called "culture". Even chimpanzees have been observed using plants as medicines.
