Hemp is the fiber and seed part of the Cannabis Sativa L. plant, opposed to the flower part of the plant which is “legally considered” marijuana.  The fiber and seeds are incredible valuable and 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 has been illegal for anyone to grow hemp in the United States as hemp is illegal under the marijuana prohibition act but Colorado has changed the laws and paved the way for industrial hemp production again in the United States(see hemp history). 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.
There is also considerable potential for other industries using hemp in the manner that the automobile industry has demonstrated is feasible. Of course, all other types of transportation vehicles from bicycles to airplanes might make use of such technology. Natural fibers have considerable advantages for use in conveyance (Karus et al. 2000): low density and weight reduction, favorable mechanical, acoustical, and processing properties (including low wear on tools), no splintering in accidents, occupational health benefits (compared to glass fibers), no off-gassing of toxic compounds, and price advantages. Additional types of composite using hemp in combination with other natural fibers, post-industrial plastics or other types of resins, are being used to produce non-woven matting for padding, sound insulation, and other applications.
The use of Cannabis as a mind-altering drug has been documented by archaeological finds in prehistoric societies in Eurasia and Africa.[84] The oldest written record of cannabis usage is the Greek historian Herodotus's reference to the central Eurasian Scythians taking cannabis steam baths.[85] His (c. 440 BCE) Histories records, "The Scythians, as I said, take some of this hemp-seed [presumably, flowers], and, creeping under the felt coverings, throw it upon the red-hot stones; immediately it smokes, and gives out such a vapour as no Grecian vapour-bath can exceed; the Scyths, delighted, shout for joy."[86] Classical Greeks and Romans were using cannabis, while in the Middle East, use spread throughout the Islamic empire to North Africa. In 1545, cannabis spread to the western hemisphere where Spaniards imported it to Chile for its use as fiber. In North America, cannabis, in the form of hemp, was grown for use in rope, clothing and paper.[87][88][89][90]

Fibres are obtained by subjecting the stalks to a series of operations—including retting, drying, and crushing—and a shaking process that completes separation from the woody portion, releasing the long, fairly straight fibre, or line. The fibre strands, usually over 1.8 metres (5.8 feet) long, are made of individual cylindrical cells with an irregular surface. The fibre, longer and less flexible than flax, is usually yellowish, greenish, or a dark brown or gray and, because it is not easily bleached to sufficiently light shades, is rarely dyed. It is strong and durable and is used for cordage—e.g., twine, yarn, rope, cable, and string—and for artificial sponges and such coarse fabrics as sacking (burlap) and canvas. In Italy some hemp receives special processing, producing whitish colour and attractive lustre, and is used to make fabric similar to linen.

Cannabis is by far the most widely cultivated, trafficked and abused illicit drug. Half of all drug seizures worldwide are cannabis seizures. The geographical spread of those seizures is also global, covering practically every country of the world. About 147 million people, 2.5% of the world population, consume cannabis (annual prevalence) compared with 0.2% consuming cocaine and 0.2% consuming opiates. In the present decade, cannabis abuse has grown more rapidly than cocaine and opiate abuse. The most rapid growth in cannabis abuse since the 1960s has been in developed countries in North America, Western Europe and Australia. Cannabis has become more closely linked to youth culture and the age of initiation is usually lower than for other drugs. An analysis of cannabis markets shows that low prices coincide with high levels of abuse, and vice versa. Cannabis appears to be price-inelastic in the short term, but fairly elastic over the longer term. Though the number of cannabis consumers is greater than opiate and cocaine consumers, the lower prices of cannabis mean that, in economic terms, the cannabis market is much smaller than the opiate or cocaine market.

In the United Kingdom, cultivation licences are issued by the Home Office under the Misuse of Drugs Act 1971. When grown for nondrug 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.[86]
Cannabis, especially the cannabinoid CBD, has also demonstrated its abilities as a powerful anti-convulsant. This property is what accounts for cannabis’ ability to reduce the severity and frequency of seizures, especially for people with epilepsy. In the United States, epilepsy is the most widely adopted qualifying condition for medical cannabis use, especially for children.
Use of industrial hemp plant and its cultivation was commonplace until the 1900s, when it was associated with its genetic sibling aka Drug-Type Cannabis species (which contain higher levels of psychoactive THC). Influential groups misconstrued hemp as a dangerous 'drug', even though it is not a 'drug' and it has the potential to be a sustainable & profitable alternative crop.
Dosage is important, because CBD can have side effects—the most common are tiredness, diarrhea, and changes in appetite and weight—so it’s best not to take more than you need. As CBD becomes more prevalent, says J. Michael Bostwick, M.D., a psychiatrist at Mayo Clinic in Rochester, MN, “I’m reasonably certain new kinds of side effects will emerge.”
The gateway effect may appear due to social factors involved in using any illegal drug. Because of the illegal status of cannabis, its consumers are likely to find themselves in situations allowing them to acquaint with individuals using or selling other illegal drugs.[256][257] Utilizing this argument some studies have shown that alcohol and tobacco may additionally be regarded as gateway drugs;[258] however, a more parsimonious explanation could be that cannabis is simply more readily available (and at an earlier age) than illegal hard drugs. In turn alcohol and tobacco are easier to obtain at an earlier point than is cannabis (though the reverse may be true in some areas), thus leading to the "gateway sequence" in those individuals since they are most likely to experiment with any drug offered.[249]
so you can just make up a new plant because it don’t get the user high? Hemp is Cannabis. PERIOD. The Farm Bill and No amount of silly dialog can create a new botanical entry. Hemp IS Cannabis. Cannabis Ruderalis, native to Russia, also called ditch weed….may be imported as Hemp but it IS Cannabis Ruderalis. The semantic name calling game is kept in motion because it serves the desires of those that profit on the confusion. Bottomline, there is Cannabis. Some Cannabis can be used to fight disease. Oligodenroglioma (in my case) and some of it can be used to alter one’s outlook……but it’s all Cannabis. Grow it in South Carolina and call it Hemp, I say God bless you, bring it to my lab and it comes out as cannabis and it’s going to be called Cannabis. Disclaimer, while I do have oligodendroglioma, I do not personally have a lab ;). M.
Not until the end of the 20th century was the specific mechanism of action of THC at the neuronal level studied.[citation needed] Researchers have subsequently confirmed that THC exerts its most prominent effects via its actions on two types of cannabinoid receptors, the CB1 receptor and the CB2 receptor, both of which are G protein-coupled receptors.[133] The CB1 receptor is found primarily in the brain as well as in some peripheral tissues, and the CB2 receptor is found primarily in peripheral tissues, but is also expressed in neuroglial cells.[134] THC appears to alter mood and cognition through its agonist actions on the CB1 receptors, which inhibit a secondary messenger system (adenylate cyclase) in a dose-dependent manner. These actions can be blocked by the selective CB1 receptor antagonist rimonabant (SR141716), which has been shown in clinical trials to be an effective treatment for smoking cessation, weight loss, and as a means of controlling or reducing metabolic syndrome risk factors.[135] However, due to the dysphoric effect of CB1 receptor antagonists, this drug is often discontinued due to these side effects.[136]
Hemp has the ability to mitigate the toxin transfer from contaminated soil into food products. This process uses phytoremediation, an organic process where toxins are absorbed by plant roots and then stored in the cellulose for disposal. Hemp phytoremediation became more well-known after the Chernobyl disaster for its use in helping grow crops that are safe for consumption.
Last year, the National Academies of Sciences, Engineering and Medicine released a nearly 500-page report on the health effects of cannabis and cannabinoids. A committee of 16 experts from a variety of scientific and medical fields analyzed the available evidence — more than 10,000 scientific abstracts in all. Because so few studies examine the effects of CBD on its own, the panel did not issue any findings about CBD specifically, but it did reach some conclusions about cannabis and cannabinoids more generally. The researchers determined that there is “conclusive or substantial evidence” supporting the use of cannabis or cannabinoids for chronic pain in adults, multiple sclerosis-related spasticity (a kind of stiffness and muscle spasms), and chemotherapy-induced nausea and vomiting. The committee also found “moderate” evidence that cannabis or cannabinoids can reduce sleep disturbances in people with obstructive sleep apnea, fibromyalgia, chronic pain and multiple sclerosis, as well as “limited” evidence that these substances can improve symptoms of Tourette’s syndrome, increase appetite and stem weight loss in people with HIV/AIDs, and improve symptoms of PTSD and anxiety.
Millennia of selective breeding have resulted in varieties that display a wide range of traits; e.g. suited for a particular environments/latitudes, producing different ratios and compositions of terpenoids and cannabinoids (CBD, THC, CBG, CBC, CBN...etc.), fibre quality, oil/seed yield etc. Hemp grown for fiber is planted closely, resulting in tall, slender plants with long fibers.
Even without changes at the federal level, there are steps that states could take on their own to make the CBD market safer. States with broad marijuana legality or CBD-only measures could mandate the calibration and regulation of testing labs, and use them to conduct safety testing. They could fund research into the benefits, dosing, and drug interactions of CBD through their public university systems. Medical boards could redouble efforts to educate physicians in what research exists regarding medical marijuana in all its incarnations, so that doctors are prepared to prescribe and manage these medications as they become available.

Did you get an answer for this? I have the exact same scenario. I'm treating my TN with Tegretol, and recently tried CBD. I think I took too much and there are some weird drug interactions with Tegretol and I felt quite stoned....was alone and talking to myself in my head thinking I was Einstein. It freaked me out a bit but I think I took too much. I'm trying lower doses again as recently my TN seems to be resisting the meds, although I have had a lot of emotional stress, which seems to be a trigger. Thanks!! Anna

So true. Hearst and Rockefeller did not want Hemp or any form of Cannabis interfering with their lucrative paper, pharmaceutical and oil industries. Hemp is versatile and renewable. It can be used for food, medicine, fuel, paper, clothing, plastic, building materials; just about anything paper and oil is used for. These bastard wealthy people have done a disservice to all people and for the sake of lining their already copiously rich pockets. They and those like them are criminals of the worst order

I’ve done a little research on the hemp and cannabis, and it looks to me like they’re both supposed to be medicine plants. From what I learned about the plants, they’ve been known to actually have multiple health benefits and even save lives of fourth stage cancer patients, sending the cancer into remission and therefore saving the patient lives. Banning this medicine plant has actually caused the deaths of many people who could have otherwise been saved by this plant. No wonder people are getting it other ways, I don’t blame them as long as it’s strictly for medical purposes. I even heard of a case where one child’s seizures were so bad they had to end up moving to Colorado as a last resort to save that little girl’s life by giving her cannabis because no other medicine worked for her.
Cannabis is first referred to in Hindu Vedas between 2000 and 1400 BCE, in the Atharvaveda. By the 10th century CE, it has been suggested that it was referred to by some in India as "food of the gods".[115] Cannabis use eventually became a ritual part of the Hindu festival of Holi. One of the earliest to use this plant in medical purposes was Korakkar, one of the 18 Siddhas.[116][117] The plant is called Korakkar Mooli in the Tamil language, meaning Korakkar's herb.[118][119]
It has been contended that hemp is notably superior to most crops in terms of biomass production, but van der Werf (1994b) noted that the annual dry matter yield of hemp (rarely approaching 20 t/ha) is not exceptional compared to maize, beet, or potato. Nevertheless, hemp has been rated on a variety of criteria as one of the best crops available to produce energy in Europe (Biewinga and van der Bijl 1996). Hemp, especially the hurds, can be burned as is or processed into charcoal, methanol, methane, or gasoline through pyrolysis (destructive distillation). As with maize, hemp can also be used to create ethanol. However, hemp for such biomass purposes is a doubtful venture in North America. Conversion of hemp biomass into fuel or alcohol is impractical on this continent, where there are abundant supplies of wood, and energy can be produced relatively cheaply from a variety of sources. Mallik et al. (1990) studied the possibility of using hemp for “biogas” (i.e. methane) production, and concluded that it was unsuitable for this purpose. Pinfold Consulting (1998) concluded that while there may be some potential for hemp biomass fuel near areas where hemp is cultivated, “a fuel ethanol industry is not expected to develop based on hemp.”

Hemp seeds contain virtually no THC, but THC contamination results from contact of the seeds with the resin secreted by the epidermal glands on the leaves and floral parts, and also by the failure to sift away all of the bracts (which have the highest concentration of THC of any parts of the plant) that cover the seeds. This results in small levels of THC appearing in hempseed oil and foods made with the seeds. Although most of the western hemp-growing world uses 0.3% THC as a maximum concentration for authorized cultivation of hemp plants, regulations in various countries allow only a much lower level of THC in human food products manufactured from the seeds. Currently, up to 10 ppm THC is permitted in seeds and oil products used for food purposes in Canada. In Germany, more stringent limits were set for food in 2000: 5 ppm in food oil, 0.005 ppm in beverages, and 0.15 ppm in all other foods. The US Drug Enforcement Administration published new regulations on hemp in the Federal Register on October 9th 2001 that in effect 4 months later would ban the food use of hemp in the US because any amount of THC would be unacceptable in foods (follow links at www.hempreport.com/). These proposals are currently being challenged by the hemp industry. Limits have been set because of concerns about possible toxicity and interference with drug tests (Grotenhermen et al. 1998). An extensive analysis of literature dealing with the toxicity of hemp is in Orr and Starodub (1999; see Geiwitz 2001 for an analysis). Because hemp food products are considered to have great economic potential, there is considerable pressure on the hemp industry in North America to reduce THC levels.
A 2015 review found that the use of high CBD-to-THC strains of cannabis showed significantly fewer positive symptoms such as delusions and hallucinations, better cognitive function and both lower risk for developing psychosis, as well as a later age of onset of the illness, compared to cannabis with low CBD-to-THC ratios.[267] A 2014 Cochrane review found that research was insufficient to determine the safety and efficacy to using cannabis to treat schizophrenia or psychosis.[268] As of 2017, the molecular mechanisms for the anti-inflammatory and possible pain relieving effects of cannabis are under preliminary research.[269]

Essential (volatile) oil in hemp is quite different from hempseed oil. Examples of commercial essential oil product products are shown in Fig. 42. The essential oil is a mixture of volatile compounds, including monoterpenes, sesquiterpenes, and other terpenoid-like compounds that are manufactured in the same epidermal glands in which the resin of Cannabis is synthesized (Meier and Mediavilla 1998). Yields are very small—about 10 L/ha (Mediavilla and Steinemann 1997), so essential oil of C. sativa is expensive, and today is simply a novelty. Essential oil of different strains varies considerably in odor, and this may have economic importance in imparting a scent to cosmetics, shampoos, soaps, creams, oils, perfumes, and foodstuffs. Switzerland has been a center for the production of essential oil for the commercial market. Narcotic strains tend to be more attractive in odor than fiber strains, and because they produce much higher numbers of flowers than fiber strains, and the (female) floral parts provide most of the essential oil, narcotic strains are naturally adapted to essential oil production. Switzerland has permitted strains with higher THC content to be grown than is allowed in other parts of the world, giving the country an advantage with respect to the essential oil market. However, essential oil in the marketplace has often been produced from low-THC Cannabis, and the THC content of essential oil obtained by steam distillation can be quite low, producing a product satisfying the needs for very low THC levels in food and other commercial goods. The composition of extracted essential oil is quite different from the volatiles released around the fresh plant (particularly limonene and alpha-pinene), so that a pleasant odor of the living plant is not necessarily indicative of a pleasant-smelling essential oil. Essential oil has been produced in Canada by Gen-X Research Inc., Regina. The world market for hemp essential oil is very limited at present, and probably also has limited growth potential.
The pulp and paper industry based on wood has considered the use of hemp for pulp, but only on an experimental basis. Hemp’s long fibers could make paper more recyclable. Since virgin pulp is required for added strength in the recycling of paper, hemp pulp would allow for at least twice as many cycles as wood pulp. However, various analyses have concluded that the use of hemp for conventional paper pulp is not profitable (Fertig 1996).
That leaves those touting CBD’s effectiveness pointing primarily to research in mice and petri dishes. There, CBD (sometimes combined with small amounts of THC) has shown promise for helping pain, neurological conditions like anxiety and PTSD, and the immune system—and therefore potentially arthritis, diabetes, multiple sclerosis, cancer, and more.
A panellized system of hemp-lime panels for use in building construction is currently under test in a European Union-funded research collaboration led by the University of Bath. The panels are being designed to assure high-quality construction, rapid on-site erection, optimal hygrothermal performance from day one, and energy- and resource-efficient buildings. The 36-month-long work programme aims to refine product and manufacturing protocols, produce data for certification and marketing, warranty, insurance cover, and availability of finance. It also includes the development of markets in Britain, France, and Spain.[32]
