Hemp it an eco-friendly plant that is often equated with marijuana, but they are actually different plants. Although both are classified as Cannibis sativa, there are hundreds of different varieties. While Marijuana is grown for its THC content, industrial hemp is grown for other properties such as its fibers, seeds or oil. The US government does not differentiate between marijuana and industrial C. sativa although over 30 other industrialized countries do (such as Canada). Currently all hemp products sold in the USA are imported.
