"Hemp" is also a name for the Cannabis plant. Some use it to mean only the low tetrahydrocannabinol (THC) strains of the plant, of fiber or and/or oilseed varieties. In modern times, hemp has been used for industrial purposes including paper, textiles, biodegradable plastics, construction, health food and fuel with modest commercial success. Since 2007, commercial success of hemp food products has grown considerably.
Hemp is one of the faster growing biomasses known, producing up to 25 tonnes of dry matter per hectare per year. A normal average yield in large scale modern agriculture is about 2.5–3.5 t/ac (air dry stem yields of dry, retted stalks per acre at 12% moisture). Approximately, one tonne of bast fiber and 2–3 tonnes of core material can be decorticated from 3–4 tonnes of good quality, dry retted straw.
For a crop, hemp is very environmentally friendly as it requires few pesticides, when not grown industrially and no herbicides. Results indicate that high yield of hemp may require high total nutrient levels (field plus fertilizer nutrients) similar to a high yielding wheat crop.
Hemp is one of the earliest domesticated plants known.
''Cannabis sativa'' L. subsp. ''sativa'' var. ''sativa'' is the variety grown for industrial use, while ''C. sativa'' subsp. ''indica'' generally has poor fiber quality and is primarily used for production of recreational and medicinal drugs. The major difference between the two types of plants is the appearance and the amount of Δ9-tetrahydrocannabinol (THC) secreted in a resinous mixture by epidermal hairs called glandular trichomes, although they can also be distinguished genetically. Oilseed and fiber varieties of ''Cannabis'' approved for industrial hemp production produce only minute amounts of this psychoactive drug, not enough for any physical or psychological effects. Typically, hemp contains below 0.3% THC, while cultivars of ''Cannabis'' grown for marijuana can contain anywhere from 2% to over 20%.
The world leading producer of hemp is China with smaller production in Europe, Chile and the Democratic People's Republic of Korea. While more hemp is exported to the United States than to any other country, the United States Government does not consistently distinguish between marijuana and the non-psychoactive ''Cannabis'' used for industrial and commercial purposes.
Within the UK, the Department for Environment, Food and Rural Affairs (Defra) has treated hemp as purely a non-food crop. Seed appears on the UK market as a legal food product, and cultivation licenses are available for this purpose. In North America, hemp seed food products are sold, typically in health food stores or through mail order. The United States Department of Agriculture estimates that "the market potential for hemp seed as a food ingredient is unknown. However, it probably will remain a small market, like those for sesame and poppy seeds."
A survey in 2003 showed that more than 95% of hemps seed sold in the EU was used for animal feed (bird seed, bait for fishing)
Hempseed is an adequate source of dietary fiber, calcium and iron, and contains antioxidants and chlorophyll. Whole hempseeds are also a good source of phosphorus, magnesium, zinc, copper and manganese.
Hempseed is usually very safe for those unable to tolerate nuts, gluten, lactose, and sugar. In fact, there are no known allergies to hemp foods. Hempseed contains no gluten and therefore would not trigger symptoms of celiac disease.
Hemp Seed contains a large dietary supplement of omega-3, higher even than walnuts which contain 6.3% of n-3.
Hemp oil has anti-inflammatory properties.
The fiber is the most valuable parts of the hemp plant. It is commonly called bast, which refers to the fibers that grow on the outside of the woody interior of the plant's stalk, and under the outer most part (the bark). Bast fibers give the plants strength. Hemp fibers can be between approximately 0.91 m (3 ft) and 4.6 m (15 ft) long, running the length of the plant. Depending on the processing used to remove the fiber from the stem, the hemp may naturally be creamy white, brown, gray, black or green.
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 produces roughly 10% more fiber than cotton or flax when grown on the same land. Hemp has been used to make paper. It was often used to make sail canvas, and the word ''canvas'' derives from ''cannabis''. Abaca, or "Manila hemp", a relative of the banana plant, replaced its use for rope. Burlap, made from jute, took over the sacking market. The paper industry began using wood pulp. The carpet industry switched over to wool, sisal, and jute, then nylon. Netting and webbing applications were taken over by cotton and synthetics.
Concrete-like blocks made with hemp and lime have been used as an insulating material for construction. Such blocks are not strong enough to be used for structural elements; they must be supported by a brick, wood, or steel frame.
The Renewable House was the UK's first home made from hemp-based materials. Construction was completed in 2009. The first US home made of hemp-based materials was completed in August 2010 in Asheville, North Carolina.
A mixture of fibreglass, hemp fiber, kenaf, and flax has been used since 2002 to make composite panels for automobiles. The choice of which bast fiber to use is primarily based on cost and availability.
In 1916, U.S. Department of Agriculture chief scientists Lyster H. Dewe and Jason L. Merrill created paper made from hemp pulp, they concluded that paper from hemp hurds was "favorable in comparison with those used with pulp wood." Modern research has not confirmed the positive finding about hemp hurds. The content of cellulose is only between 32% and 38%. The actual production of hemp fiber in the U.S continued to decline until 1933 to around 500 tons/year. Between 1934-35, the cultivation of hemp began to increase but still at a very low level and with no significant increase of paper from hemp.
Hemp has never been used for commercial high-volume paper production due to its relatively high processing cost. Currently there is a small niche market for hemp pulp, for example as cigarette paper. Hemp fiber is mixed with fiber from other sources than hemp. In 1994 there was no significant production of 100% true hemp paper. World hemp pulp production was believed to be around 120,000 tons per year in 1991 which was about 0.05% of the world's annual pulp production volume. The total world production of hemp fiber had in 2003 declined to about 60 000 to 80 000 ton. This can be compared to a typical pulp mill for wood fiber, which is never smaller than 250,000 tons per annum. The cost of hemp pulp is approximately six times that of wood pulp, mostly because of the small size and outdated equipment of the few hemp processing plants in the Western world, and because hemp is harvested once a year (during August) and needs to be stored to feed the mill the whole year through. This storage requires a lot of (mostly manual) handling of the bulky stalk bundles. Another issue is that the entire hemp plant cannot be economically prepared for paper production. While the wood products industry uses nearly 100% of the fiber from harvested trees, only about 25% of the dried hemp stem — the bark, called bast — contains the long, strong fibers desirable for paper production. All this accounts for a high raw material cost. Hemp pulp is bleached with hydrogen peroxide, a process today also commonly used for wood pulp.
Hemp, because of its height, dense foliage and its high planting density as a crop, is a very effective and long used method of killing tough weeds in farming by minimizing the pool of weed seeds of the soil. Using hemp this way can help farmers avoid the use of herbicides, to help gain organic certification and to gain the benefits of crop rotation ''per se''. Due to its rapid, dense growth characteristics, in some jurisdictions hemp is considered a prohibited noxious weed, much like Scotch Broom.
Filtered hemp oil can be used directly to power diesel engines. In 1892, Rudolf Diesel invented the diesel engine, which he intended to fuel "by a variety of fuels, especially vegetable and seed oils, which earlier were used for oil lamps, i.e. the Argand lamp."
Millennia of selective breeding have resulted in varieties that look quite different. Also, breeding since circa 1930 has focused quite specifically on producing strains which would perform very poorly as sources of drug material. Hemp grown for fiber is planted closely, resulting in tall, slender plants with long fibers. Ideally, according to Britain's Department for Environment, Food and Rural Affairs, the herb should be harvested before it flowers. This early cropping is done because fiber quality declines if flowering is allowed and, incidentally, this cropping also pre-empts the herb's maturity as a potential source of drug material. However, in these strains of industrial hemp the tetrahydrocannabinol (THC) content would have been very low, regardless.
The name ''Cannabis'' is the genus and was the name favored by the 19th century medical practitioners who helped to introduce the herb's drug potential to modern English-speaking consciousness. ''Cannabis'' for non-drug purposes (especially ropes and textiles) was then already well known as hemp.
The name "marijuana" is Spanish in origin and associated almost exclusively with the herb's drug potential.
In Western Europe, nobody banned the cultivation of hemp in the 1930s but the commercial cultivation ceased almost anyhow in the decades after the 1930s. Hemp was simply ousted by artificial fibres.
From the 1950s to the 1980s, the Soviet Union was the world's largest producer (3,000 km² in 1970). The main production areas were in Ukraine, the Kursk and Orel regions of Russia, and near the Polish border. Since its inception in 1931, the Hemp Breeding Department at the Institute of Bast Crops in Hlukhiv (Glukhov), Ukraine, has been one of the world's largest centers for developing new hemp varieties, focusing on improving fiber quality, per-hectare yields, and low THC content.
In Japan, hemp was historically used as paper and a fiber crop. There is archaeological evidence cannabis was used for clothing and the seeds were eaten in Japan back to the Jōmon period (10,000 to 300 BCE). Many Kimono designs portray hemp, or ''asa'' (), as a beautiful plant. In 1948, marijuana was restricted as a narcotic drug. The ban on marijuana imposed by the United States authorities was alien to Japanese culture, as the drug had never been widely used in Japan before. Though these laws against marijuana are some of the world's strictest, allowing five years imprisonment for possession of the drug, they exempt hemp growers, whose crop is used to make robes for Buddhist monks and loincloths for sumo wrestlers. Because marijuana use in Japan has doubled in the past decade, these "loopholes" have recently been called into question.
FAO argue that an optimum yield of hemp fiber is more than 2 tonnes per ha, while average yields are around 650 kg/ha.
There are a lot of very uncertain, easily misleading and sometimes clearly incorrect numbers about the yield from hemp in ton/hectare or pounds/acre etc. on the Internet where it is not specified if the numbers is relevant for the total biomass or the total yield of biomass or the total yield of dried stalk or the total yield of fiber from the bark (and is the numbers for wet or dry material? Hemp can contain a lot of water) In modern industrial agriculture is about 42% of the plants' biomass returned to the soil in the form of leaves, roots and tops.
Smallholder plots are usually harvested by hand. The plants are cut at 2 to 3 cm above the soil and left on the ground to dry. Mechanical harvesting is now common, using specially adapted cutter-binders or simpler cutters.
The cut hemp is laid in swathes to dry for up to four days. This was traditionally followed by ''retting'', either water retting (the bundled hemp floats in water) or dew retting (the hemp remains on the ground and is affected by the moisture in dew, and by molds and bacterial action). Modern processes use steam and machinery to separate the fiber, a process known as Thermomechanical pulping.
A nominal, if not legal distinction is often made between hemp, with concentrations of the psychoactive chemical THC far too low to be useful as a drug, and ''Cannabis'' used for medical, recreational, or spiritual purposes.
Hemp use dates back to the Stone Age, with hemp fiber imprints found in pottery shards in China and Taiwan over 7,000 years old. They were also later used to make clothes, shoes, ropes, and an early form of paper. Contrary to the traditional view that Cai Lun invented paper in around 105 AD, specimens of hemp paper were found in the Great Wall of China dating back 200 years earlier.
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.
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.
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. It was repealed by an overriding law in 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.
France is Europe's biggest producer with 8,000 hectares cultivated. 70-80 % of the hemp fibre produced in Europe in 2003 was used for specialty pulp for cigarette papers and technical applications. About 15% is used in the automotive sector and 5-6% were used for insulation mats. Approximately 95% of hurds were used as animal bedding, while almost 5% were used in the building sector.
Canada Commercial production (including cultivation) of industrial hemp has been permitted in Canada since 1998 under licenses and authorization issued by Health Canada (9,725 ha in 2004, 5450 ha in 2009).
The United Kingdom, and Germany all resumed commercial production in the 1990s. British production is mostly used as bedding for horses; other uses are under development. The largest outlet for German fibre is composite automotive panels. Companies in Canada, the UK, the United States and Germany, among many others, process hemp seed into a growing range of food products and cosmetics; many traditional growing countries still continue to produce textile-grade fibre.
Hemp is not legal to grow in the U.S. under Federal law because of its relation to marijuana, and any imported hemp products must meet a zero tolerance level. It is considered a controlled substance under the Controlled Substances Act (P.L. 91-513; 21 U.S.C. 801 et seq.). Some states have defied Federal law and made the cultivation of industrial hemp legal. These states — North Dakota, Hawaii, Kentucky, Maine, Maryland,Oregon,California,Montana, West Virginia and Vermont — have not yet begun to grow hemp because of resistance from the federal Drug Enforcement Administration.
Uruguay has also approved a project of hemp production as of the second half of 2010.
In the United Kingdom, these licences are issued by the Home Office under the Misuse of Drugs Act 1971. When grown for non-drug purposes, hemp is referred to as industrial hemp, and a common product is fibre for use in a wide variety of products, as well as the seed for nutritional aspects and for the oil. Feral hemp or ditch weed is usually a naturalized fibre or oilseed strain of ''Cannabis'' that has escaped from cultivation and is self-seeding.
Victoria, Queensland and, most recently, New South Wales issue licences to grow hemp for industrial use. Victoria was an early adopter in 1998, and has reissued the regulation in 2008. Queensland has allowed industrial production under licence since 2002, where the issuance is controlled under the Drugs Misuse Act 1986. Most recently, New South Wales now issues licences under a law, the Hemp Industry Regulations Act 2008 (No 58), that came into effect as of 6 November 2008.
Vermont and North Dakota have passed laws enabling hemp licensure. Both states are waiting for permission to grow hemp from the DEA. Currently, North Dakota representatives are pursuing legal measures to force DEA approval. Oregon has licensed industrial hemp .

Joseph "Joe" Rogan (born August 11, 1967) is an American comedian, video blogger, actor, writer, martial artist, activist and color commentator for the Ultimate Fighting Championship.
From 1995-1999, Rogan co-starred on the critically acclaimed comedy NewsRadio. He portrayed Joe Garrelli, the electrician at WNYX, a news radio station in New York City.
In 2002, he appeared on the episode "A Beautiful Mind" of Just Shoot Me as Chris, Maya Gallo's boyfriend.
In 2010 Joe Rogan released his stand up DVD Talking Monkeys In Space. It was 68 minutes of unedited and uncensored material.
In 2011, Rogan played his first major character in a movie in the Kevin James movie ''Zookeeper''.
He is slated to play himself in an upcoming action-comedy starring Kevin James called Here Comes the Boom, set to be released in the summer of 2012.
In 1996, Rogan began training in Brazilian Jiu-Jitsu under Carlson Gracie at his school in Hollywood, California. After Gracie relocated to Chicago, Rogan later began training under Jean Jacques Machado, (a cousin of the Gracie family), eventually earning his brown belt under Machado. In addition, Rogan holds a brown belt in 10th Planet Jiu-Jitsu under Eddie Bravo.
In December 2009, Rogan began hosting a regular podcast with concurrent live Ustream availability. Frequently co-hosted by his friend and the show's producer Brian "Redban" Reichle, the podcast features an array of guests from the pursuits of comedy, acting and Mixed Martial Arts. Now known as ''The Joe Rogan Experience'', the show is regularly found in the Apple iTunes top 10 most downloaded comedy, and was named one of iTunes "Best of 2010" audio podcasts in its first year. He refers to himself as a werewolf commonly on the podcast, admittedly after the Twilight series.
