Marijuana originated in Central and Southern Asia. It was discovered growing in the wild in China. China is known principally for its tea and opium, the great number of its people, itâs massive high-rises, but not really known for the discovery place of marijuana.
The difference is in its use. Hemp and Marijuana both come from the same plant-Cannabis Sativa L. The term 'Hemp' commonly refers to the industrial/commercial use of the cannabis stalk and seed for textiles, foods, papers, body care products, detergents, plastics and building materials.owever, since the 1950s it has been lumped into the same category of marijuana, and thus the extremely versatile crop was doomed in the United States.
