Hemp was used extensively by the United States during World War II to make uniforms, canvas, and rope.[144] Much of the hemp used was cultivated in Kentucky and the Midwest. During World War II, the U.S. produced a short 1942 film, Hemp for Victory, promoting hemp as a necessary crop to win the war.[143] U.S. farmers participated in the campaign to increase U.S. hemp production to 36,000 acres in 1942.[145] This increase amounted to more than 20 times the production in 1941 before the war effort.[145]
Hemp is possibly one of the earliest plants to be cultivated.[107][108] An archeological site in the Oki Islands near Japan contained cannabis achenes from about 8000 BC, probably signifying use of the plant.[109] Hemp use archaeologically dates back to the Neolithic Age in China, with hemp fiber imprints found on Yangshao culture pottery dating from the 5th millennium BC.[106][110] The Chinese later used hemp to make clothes, shoes, ropes, and an early form of paper.[106] The classical Greek historian Herodotus (ca. 480 BC) reported that the inhabitants of Scythia would often inhale the vapors of hemp-seed smoke, both as ritual and for their own pleasurable recreation.[111]

In the United States, the public's perception of hemp as marijuana has blocked hemp from becoming a useful crop and product,"[57] in spite of its vital importance prior to World War II.[58] Ideally, according to Britain's Department for Environment, Food and Rural Affairs, the herb should be desiccated and harvested towards the end of flowering. This early cropping reduces the seed yield but improves the fiber yield and quality.[59] In these strains of industrial hemp* the tetrahydrocannabinol (THC) content would have been very low.[57]
Hemp has been grown for millennia in Asia and the Middle East for its fibre. Commercial production of hemp in the West took off in the eighteenth century, but was grown in the sixteenth century in eastern England.[148] Because of colonial and naval expansion of the era, economies needed large quantities of hemp for rope and oakum. In the early 1940s, world production of hemp fiber ranged from 250 000 to 350 000 metric tonnes, Russia was the biggest producer.[130]
Hemp can be used as a "mop crop" to clear impurities out of wastewater, such as sewage effluent, excessive phosphorus from chicken litter, or other unwanted substances or chemicals. Additionally, hemp is being used to clean contaminants at the Chernobyl nuclear disaster site, by way of a process which is known as phytoremediation—the process of clearing radioisotopes and a variety of other toxins from the soil, water, and air.[46]

The oil contained in the hemp seed is 75-80% polyunsaturated fatty acids (the good fats) and only 9-11% of the lesser desired saturated fatty acids. Hemp seed oil is reputed to be the most unsaturated oil derived from the plant kingdom. The essential fatty acids (EFAs) contained in hemp seed oil are deemed essential because our bodies do not naturally produce them. This means that they must be obtained from the food we eat.

Considering its popularity from long ago, when even our forefathers appreciated the value of hemp seeds, it seems unusual that the plant would have such a bad reputation today. Both George Washington and Thomas Jefferson grew hemp plants in their gardens. Hemp paper was even used for the Declaration of Independence, and Benjamin Franklin produced hemp paper at his mill. The environmental advantages and nutritional benefits of growing industrial hemp seem to many to be worth lifting its restrictions.
Hemp is the common term for a variety of plants in the Cannabis family. This beneficial and versatile plant can be turned into fibers, oil, wax, resin, cloth, fuel, and a wide range of other useful products. Hemp grows all over the world, as it is a very resilient plant which can grow in a variety of environmental conditions. The main concern that people have with edible hemp products, is that it comes from a cannabis plant. However, hemp seeds that are sold for consumption have less than 0.5% THC and are safe to eat.
