WHAT IS HEMP?
Hemp is a variety of cannabis that is grown for the fiber and seeds. The fiber and seeds are incredibly valuable and that is why hemp is often called a “cash crop”. Hemp is a very hearty plant and grows very quickly in very diverse soil conditions. Cultivation of hemp for industrial purposes has been done by many civilizations for over 12,000 years. Industrial hemp was the desired fiber used to manufacture rope, canvas, paper, and clothing until alternative textiles and synthetics for these purposes were discovered. Although China has been the largest hemp producer over the years, other countries such as Australia and Canada are catching up. It was illegal for anyone to grow hemp in the United States as hemp was illegal under the marijuana prohibition act. Now hemp oils, hemp plastics, hemp building materials and many hemp fiber products can be seen and purchased on the market. Hemp is truly an amazing plant with the potential to help “green up” many industries.
Traditionally, hemp fiber has been a very coarse fiber when raw, which made it well suited to rope but less than ideal for clothing designed to be worn against delicate human skin. Advances in breeding of the plants and treatment/processing of the fibers have resulted in a much finer, softer hemp fiber, which is ideal for weaving into hemp clothing, fabrics and rope.
The “re-”growth of industrial hemp in the United States is heavily regulated, although the neighbouring nation of Canada successfully grows hemp commercially. Since becoming legal to grow again in Canada, the crop has taken off and has become a booming multi-million dollar export. Hemp building materials are another growing segment of the hemp industry. Canada is now a leader in the global hemp food/health marketplace. Canadian hemp products can be found in many hemp markets now in the United States and the world over.
In addition to providing useful fibers, hemp seed also has high nutritional value. and the plant can be used to make biodegradable plastics, some fuels, and a variety of other things. Hemp foods including but not limited to hemp energy bars, hemp salad dressing,hemp milk, hemp protein shakes, hemp oil gel caps and hemp protein powder are among some of the health products being produced today.
HISTORY OF HEMP
Hemp use archaeologically dates back to the Neolithic Age in China, with hemp fiber imprints found on Yangshao culture pottery dating from the 5th century BC. The Chinese later used hemp to make clothes, shoes, ropes, and an early form of paper. 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.
Textile expert Elizabeth Wayland Barber summarizes the historical evidence that Cannabis sativa, “grew and was known in the Neolithic period all across the northern latitudes, from Europe (Germany, Switzerland, Austria, Romania, the Ukraine) to East Asia (Tibet and China), but, textile use of Cannabis sativa does not surface for certain in the West until relatively late, namely the Iron Age. I strongly suspect, however, that what catapulted hemp to sudden fame and fortune as a cultigen and caused it to spread rapidly westwards in the first millennium B.C. was the spread of the habit of pot-smoking from somewhere in south-central Asia, where the drug-bearing variety of the plant originally occurred. The linguistic evidence strongly supports this theory, both as to time and direction of spread and as to cause.”
Jews living in Palestine in the 2nd century were familiar with the cultivation of hemp, as witnessed by a reference to it in the Mishna (Kil’ayim 2:5) as a variety of plant, along with Arum, that sometimes takes as many as three years to grow from a seedling. In late medieval Germany and Italy, hemp was employed in cooked dishes, as filling in pies and tortes, or boiled in a soup. Hemp in later Europe was mainly cultivated for its fibers, and was used for ropes on many ships, including those of Christopher Columbus. The use of hemp as a cloth was centered largely in the countryside, with higher quality textiles being available in the towns.
The Spaniards brought hemp to the Western Hemisphere and cultivated it in Chile starting about 1545. However, in May 1607, “hempe” was among the crops Gabriel Archer observed being cultivated by the natives at the main Powhatan village, where Richmond, Virginia is now situated; and in 1613, Samuell Argall reported wild hemp “better than that in England” growing along the shores of the upper Potomac. As early as 1619, the first Virginia House of Burgesses passed an Act requiring all planters in Virginia to sow “both English and Indian” hemp on their plantations. The Puritans are first known to have cultivated hemp in New England in 1645.
United States “Marihuana” production permit. In the United States, hemp cultivation is legally prohibited, but during World War II farmers were encouraged to grow hemp for cordage, to replace Manila hemp previously obtained from Japanese-controlled areas. The U.S. government produced a film explaining the uses of hemp, called Hemp for Victory. In 1937, the Marihuana Tax Act of 1937 was passed in the United States. It levied a tax on anyone who dealt commercially in cannabis, hemp, or marijuana. This law was ruled unconstitutional by the Supreme Court in a unanimous verdict decided in Leary v. United States, and ultimately superseded by the Controlled Substances Act of 1970.
Hemp was used extensively by the United States during World War II. Uniforms, canvas, and rope were among the main textiles created from the hemp plant at this time. Much of the hemp used was cultivated in Kentucky and the Midwest. Historically, hemp production had made up a significant portion of antebellum Kentucky’s economy. Before the American Civil War, many slaves worked on plantations producing hemp.
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. By the early twentieth century, the advent of the steam engine and the Diesel engine ended the reign of the sailing ship. The production of iron and steel for cable and ships’ hulls further eliminated natural fibres in marine use. Hemp had long since fallen out of favour in the sailing industry in preference to Manila hemp.
