The area around Ayding Lake in the Turpan region was said to be the territory of the Gushi people. According to historical accounts, these people "lived in tents, followed the grasses and waters, and had considerable knowledge of agriculture. They owned cattle, horses, camels sheep and goats. There were proficient with bows and arrows".2 The Gushi and the kingdom of Kroran were linked in the account of Zhang Qian, presuamably because they were under the control of the Xiongnu. In the years around 60 BC, Gushi fell to the Chinese after the Battle of Jushi and was subsequently known as Jushi.
The Yanghai Tombs, a vast ancient cemetery (54 000 m2) attributed to this culture, have revealed the 2,700-year-old grave of a shaman. Near the head and foot of the shaman lay a large leather basket and wooden bowl filled with 789g of cannabis, superbly preserved by climatic and burial conditions. An international team demonstrated that this material contained tetrahydrocannabinol, the psychoactive component of cannabis. The cannabis was presumably employed by this culture as a medicinal or psychoactive agent, or an aid to divination. This is the oldest documentation of cannabis as a pharmacologically active agent.3
The cache of cannabis is about 2,700 years old and was clearly "cultivated for psychoactive purposes," rather than as fibre for clothing or as food, says a research paper in the Journal of Experimental Botany.3 The 789 grams of dried cannabis was buried alongside a light-haired, blue-eyed Caucasian man, likely a shaman of the Gushi culture, near Turpan in northwestern China. The extremely dry conditions and alkaline soil acted as preservatives, allowing a team of scientists to carefully analyze the stash, which still looked green though it had lost its distinctive odour.
