Cannabis sativa has been cultivated by humans for thousands of years both as a narcotic and also for making hemp fabrics. Brand new genetic and archaeological evidence places the original domestication event in China, but indicates that the plant was mainly spread by Indo-European peoples such as the Yamnaya and the Scythians. Cannabis was used in the funerary and religious rites in many pagan religions as well as in ancient Jewish rites in Israel.
