cultivation of cannabis can be traced back at least 12,000 years,
which places the plant among humanity's oldest cultivated crops.
Cannabis plants are believed to have evolved in Central Asia in the
regions of Mongolia and southern Siberia. The earliest cultural
evidence of Cannabis comes from the oldest known Neolithic culture in
China, the Yangshao, who appeared along the Yellow River valley.
From 5,000 to 3,000 B.C the economy of the Yangshao was
cannabis-driven. Archaeological evidence shows they wore hemp
clothing, wove hemp, and produced hemp pottery.
