Economic Application of Hemp
1) Hemp is used to make cordage of greatly varying tensile strength, clothing, food, and the oils from the seeds can be made into paint or used for cooking.
2) In Europe and China hemp fibers are increasingly used in plasters and composites answering to many construction and manufacturing needs.
3) Mercedes-Benz uses a "biocomposite" principally of hemp in the interior panels of some of its automobiles.
Hemp use in the United States is severely depressed by laws supported by governmental drug enforcement bodies, which fear that high T.H.C. plants will be grown amidst the ultra-low T.H.C. plants used for hemp production.
Efforts are underway to change these laws, allowing American farmers to compete in the growing markets for this crop. As of 2006, China controls roughly 40% of the world's hemp fiber.
Hemp seeds are also found in wild bird seed mix.
4) Housing--
70% of the Cannabis plant's total weight is made up of the 'hurd' or woody inner core.
This part of the plant does not contain tetrahydrocannabinol (THC) and can be used in housing construction.
The silica leached from soil by the plant combined with unslaked lime (calcium oxide) forms a chemical bond similar to cement which is both fire and waterproof.
5) Food--
Hemp (the seed) may be grown also for food. The seeds are comparable to sunflower seeds, and can be used for baking, like sesame seeds.
Products range from cereals to frozen waffles. A few companies produce value added hemp seed items that include the oils of the seed, whole hemp grain (which is sterilized as per international law), hulled hemp seed (the whole seed without the mineral rich outer shell), hemp flour, hemp cake (a by-product of pressing the seed for oil) and hemp protein powder. Hemp is also used in some organic cereals.
Within the UK, the Department for Environment, Food and Rural Affairs (Defra) treats hemp as purely a non-food crop. Seed can and does appear on the UK market as a legal food product although cultivation licences are not available for this purpose. In North America, hemp seed food products are sold in small volume, typically in health food stores or by mail order.
6) Nutrition---
30–35% of the weight of hempseed is oil containing 80% of the unsaturated essential fatty acids (EFAs), linoleic acid (LA, 55%) and linolenic acid (ALA, 21–25%).
These are not manufactured by the human body and must be supplied by food. The proportions of linoleic acid and linolenic acid in hempseed oil are perfectly balanced to meet human requirements for EFAs, including gamma-linoleic acid (GLA).
Unlike flax oil and others, hempseed oil can be used continuously without developing a deficiency or other imbalance of EFAs.
Hemp also contains 31% complete and highly-digestible protein, 1/3 as edestin protein and 2/3 as albumin protein. Its high quality Amino Acid composition is closer to "complete" sources of proteins (meat, milk, eggs) than all other oil seeds except soy .
7) Fiber----
The use of hemp for fiber production has declined sharply over the last two centuries, but before the industrial revolution, hemp was a popular fiber because it is strong and grows quickly.
It was used to make the first pieces of fabric ever found and was therefore also used as the first material for paper (paper used to be made of rags).
It was used to make canvas, and the word canvas itself is derived from cannabis.
Hemp was very popular, and it had many uses. However, as other coarse-fibre plants were more widely grown, hemp fibre was replaced in most roles.
Hemp rope is notorious for breaking due to rot.
Hemp rope rots from the inside out, and thus the rope looks good until it breaks. Hemp rope used in the age of sail was protected by tarring, a labor-intensive process and the reason for the Jack Tar nickname for sailors. Hemp rope was phased out when Manila, which does not require tarring, became available.
There is a niche market for hemp paper, but the cost of hemp pulp is approximately six times that of wood pulp, mostly due to the small size and outdated equipment of the few hemp processing plants in the Western world. Hemp pulp is processed with hydrogen peroxide, avoiding the sulphuric acid waste problem associated with wood pulping. Kenaf is another fast-growing plant which can be used as a replacement for wood pulp. Kenaf paper has been produced in commercial quantities since 1992.
A modest hemp clothing industry exists. Recent developments in processing have made it possible to soften up coarse fibres to a wearable level.
8) Medical cannabis refers to the use of the drug Cannabis as a physician recommended herbal therapy, most notably as an antiemetic. The term medical marijuana post-dates the U.S. Marijuana Tax Act of 1937, the effect of which made cannabis prescriptions illegal in the United States.
Due to widespread illegal use of cannabis as a recreational drug its legal or licensed use in medicine is now a controversial issue in most countries.

All of those long winded answers aside, hemp can be used for cloth, the seeds can make a very useful lubricating oil, sailing ships used it to make rope for sails, and the Declaration of Independence was written on Hemp Paper.
Don't forget brownies, also ;)

The fiber and the plant Cannabis sativa. It should not be confused with Manila hemp, which is not related to true hemp. Hemp contains the drug THC (tetrahydrocannabinol). See also Abaca; Marijuana.
Hemp fiber, which for many years was the major raw material used in the manufacture of rope, now is used mostly in the production of small twines, linenlike fabrics and canvases, and, to some extent, in making special types of paper. See also Natural fiber.
Hemp is an annual crop, most of which is produced in Eastern Europe and mainland China, with some production in South Korea, Turkey, Italy, and Canada.

Hemp is the common name for a non-psychoactive variety of Cannabis sativa that is usually grown for industrial use. Cultivation licenses may be issued in the European Union and Canada. In the United Kingdom licences are issued by the Home Office under the Misuse of Drugs Act 1971. When grown for industrial purposes hemp is often called industrial hemp (or industrial cannabis), and a common product is fiber for use in a wide variety of products. Feral hemp, or ditchweed, is wild growing fiber or oilseed varieties of Cannabis that have escaped from cultivation, have naturalized, and are now self-seeding annuals.
Cannabis sativa subsp. sativa is the major hemp crop, while C. sativa subsp. indica has poor fiber quality, and is used for production of recreational and medicinal drugs. The chief difference lies in the amount of delta-9 tetrahydrocannabinol, or THC, secreted in resins from epidermal glands— the strains of Cannabis sativa used for industrial hemp production contain almost none of this resin while other varieties secrete significant amounts. Some botanists dispute these labels and more genetic analysis will be needed to gain consensus.

Hemp is very beneficial to the environment. It helps eliminate deforestation because it produces four times as much paper as trees and grows much faster (up to 16 feet in only 110 days). According to the American Hemp Historic Association, when hemp is nourished with milk, or any high calcium fluid, it grows stronger and faster. Hemp paper also can be bleached with little or no chemicals.[citation needed] Hemp also helps reduce the use of pesticides. Hemp is an ecologically friendly substitute for cotton and while cotton uses 25% of the Earth's pesticides, hemp does not need any.[citation needed] Cotton also requires heavy irrigation while hemp flourishes with very little watering.[citation needed]
Hemp use dates back to the Stone Age, with hemp fibre imprints found in pottery shards in China and Taiwan over 10,000 years old. These ancient Asians also used the same fibres to make clothes, shoes, ropes, and an early form of paper.
Hemp cloth was more common than linen until the mid 14th century. The use of hemp as a cloth was centered largely in the countryside, with higher quality textiles being available in the towns. Virtually every small town had access to a hemp field.
In late medieval Germany and Italy hemp was employed in cooked dishes, as filing in pies and tortes, or boiled in a soup.
Thomas Jefferson drafted the United States Declaration of Independence on hemp paper.
In the Napoleonic era, many military uniforms were made of hemp. While hemp linens were coarser than those made of flax, the added strength and durability of hemp, as well as the lower cost, meant that hemp uniforms were preferred.
Hemp was used extensively by the United States during WWII. Uniforms, canvas, and rope were among the main textiles created from the hemp plant at this time. Much of the hemp used was planted in the Midwest and Kentucky. Historically, hemp production made up a significant portion of Kentucky's economy and many slave plantations located there focused on producing hemp.[citation needed]
By the early twentieth century, the advent of the steam engine and the diesel engine ended the reign of the sailing ship. The advent of iron and steel for cable and ship's hulls further eliminated natural fibers in marine use. The invention of artificial fibers in the late thirties by DuPont further put strain on the market. It is documented that DuPont lobbied the government to make Cannabis a Class 1 drug, a narcotic, in order to vilify by association hemp, and effect the transfer to polyester ropes.[citation needed]
In the last decade hemp has been widely promoted as a crop for the future. This is stimulated by new technologies which make hemp suitable for industrial paper manufacturing, use as a renewable energy source (biofuel), and the use of hemp derivatives as replacement for petrochemical products.
Hemp Plastic is a new techology based on 20-100% hemp fibre based plastics that can be moulded or injection moulded. The use of fibre re-inforced composites and other natural plastics are expected to become more popular as oil prices rise and the world becomes more environmentally aware.
The increased demand for health food has stimulated the trade in shelled hemp seed, hemp protein powder and hemp oil as well as finished and ready-to-eat food products using these derivatives as ingredients. Hemp oil is increasingly being used in the manufacturing of bodycare products.
