The applicant, including all corporate officers, must be fingerprinted at a law enforcement agency. The law enforcement agency, not the applicant, must send the fingerprint sheet to the Department (80-18-103, MCA). Most local law enforcement offices provide fingerprinting services. The completed application and copy of the law enforcement submitted fingerprints will be submitted for DEA review and approval. The DEA may place additional requirements on the Department or the applicant for participation or continuation of the program. At the end of the licensure, program participants must submit an agricultural/agronomic report regarding their experience with their hemp crop. The report shall include the approximate yield in pounds per acre and the method used to devitalize the seed. All seed must be devitalized after harvest and no seed production for future planting is allowed under the Montana Industrial Hemp Pilot Program.
Various strains of "medical marijuana" are found to have a significant variation in the ratios of CBD-to-THC, and are known to contain other non-psychotropic cannabinoids.[61] Any psychoactive marijuana, regardless of its CBD content, is derived from the flower (or bud) of the genus Cannabis. Non-psychoactive hemp (also commonly-termed industrial hemp), regardless of its CBD content, is any part of the cannabis plant, whether growing or not, containing a ∆-9 tetrahydrocannabinol concentration of no more than three-tenths of one percent (0.3%) on a dry weight basis.[62] Certain standards are required for legal growing, cultivating and producing the hemp plant. The Colorado Industrial Hemp Program registers growers of industrial hemp and samples crops to verify that the THC concentration does not exceed 0.3% on a dry weight basis.[62]
Despite advances in pharmacologic and nonpharmacologic management, nausea and vomiting (N/V) remain distressing side effects for cancer patients and their families. Dronabinol, a synthetically produced delta-9-THC, was approved in the United States in 1986 as an antiemetic to be used in cancer chemotherapy. Nabilone, a synthetic derivative of delta-9-THC, was first approved in Canada in 1982 and is now also available in the United States.[24] Both dronabinol and nabilone have been approved by the U.S. Food and Drug Administration (FDA)for the treatment of N/V associated with cancer chemotherapy in patients who have failed to respond to conventional antiemetic therapy. Numerous clinical trials and meta-analyses have shown that dronabinol and nabilone are effective in the treatment of N/V induced by chemotherapy.[25-28] The National Comprehensive Cancer Network Guidelines recommend cannabinoids as breakthrough treatment for chemotherapy-related N/V.[29] The American Society for Clinical Oncology (ASCO) antiemetic guidelines updated in 2017 recommends that the FDA-approved cannabinoids, dronabinol or nabilone, be used to treat N/V that is resistant to standard antiemetic therapies.[30]
Lewis has even built his own machine to process the hemp. Using a Patagonia grant, he created a piece of equipment called a “break”, which incorporates design details borrowed from early European flax roller breaks. Lewis’s invention is a one-of-a-kind machine. It works by separating the hemp’s woody core from the fibers which are used in textiles. According to Lewis, the highest quantity of finished hemp fiber processed in a day using the machine is around 60lbs – which means about 600lbs of raw material. A newer version of the break, which Lewis is currently working on, will have a capacity to produce about 2000lbs per day of raw material.
Today, you’ll find nutty-tasting (hull-less) hemp seeds and their oils baked in breads, cookies, and cakes, blended in smoothies, or tossed into quinoa and pasta dishes, burgers, pizza, vegetables sautés, soups, salads, oatmeal, yogurt, trail mix, and salad dressings. It’s a niche market, with a growing number of specialty outlets due to a growing understanding of this food’s nutritional benefits.
Approximately 65% of sub-Saharan Africa’s agricultural land is degraded, according to data collected in 2015, resulting in food insecurity and a declining economy in a region where the agricultural industry employs more than half of the total labor force. Hemp’s soil nutrient replenishing properties could be the key to reviving crop production, providing a novel food source (hemp seeds) and boosting the agro-based economies of South Africa and other hemp-cultivating sub-Saharan countries.
Senate Majority Leader Mitch McConnell (R-KY) introduced new legislation in April that would declassify non-psychoactive cannabis varieties -- more commonly referred to as hemp -- from the Controlled Substances Act. The legislative proposal comes as part of McConnell's Hemp Farming Act of 2018, which would remove barriers placed on banking access and water rights in addition to legalizing the 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.”

CBD’s potential usefulness in treating certain conditions is yet another argument in favor of legalizing the entire cannabis plant. Removing cannabis from the federal list of Schedule I narcotics that are illegal under the Controlled Substances Act would allow scientists to research its full medical potential and pharmaceutical companies in the United States to develop marijuana-based drugs and submit them for FDA approval. Government-regulated labs could test products like CBD oil to ensure safety and quality. Doctors could prescribe marijuana- based medicines with full knowledge of potential side effects and drug interactions, and without fear of losing their medical licenses or being thrown in jail.
Other desirable features of hemp fibers are strength and durability (particularly resistance to decay), which made hemp useful in the past for rope, nets, sail-cloth, and oakum for caulking. During the age of sailing ships, Cannabis was considered to provide the very best of canvas, and indeed this word is derived from Cannabis. Several factors combined to decrease the popularity of hemp in the late 19th and early 20th centuries. Increasing limitation of cheap labor for traditional production in Europe and the New World led to the creation of some mechanical inventions, but too late to counter growing interest in competitive crops. Development of other natural fibers as well as synthetic fibers increased competition for hemp’s uses as a textile fiber and for cordage. Hemp rag had been much used for paper, but the 19th century introduction of the chemical woodpulping process considerably lowered demand for hemp. The demise of the sail diminished the market for canvas. Increasing use of the plant for drugs gave hemp a bad image. All this led to the discontinuation of hemp cultivation in the early and middle parts of the 20th century in much of the world where cheap labor was limited. In the 19th century softer fabrics took over the clothing market, and today, hemp constitutes only about 1% of the natural fiber market. At least some production of hemp for fiber still occurs in Russia, China, the Ukraine, Poland, Hungary, the countries of the former Yugoslavia, Romania, Korea, Chile, and Peru. There has been renewed interest in England, Australia, and South Africa in cultivating fiber hemp. Italy has an outstanding reputation for high-quality hemp, but productivity has waned for the last several decades. In France, a market for high-quality paper, ironically largely cigarette paper, has developed (such paper is completely free of the intoxicating resin). Modern plant breeding in Europe has produced several dozen hemp strains, although by comparison with other fiber crops there are relatively few described varieties of hemp. Since World War II, breeding has been concerned most particularly with the development of monoecious varieties. Gehl (1995) reviewed fiber hemp development in Canada in the early 20th century, and concluded that the prospects for a traditional fiber industry were poor. However, as outlined below, there are now many non-traditional usages for hemp fiber which require consideration. Hemp long fiber is one of the strongest and most durable of natural fibers, with high tensile strength, wet strength, and other characteristics that make it technically suited for various industrial products (Karus and Leson 1996).
Hemp paper are paper varieties consisting exclusively or to a large extent from pulp obtained from fibers of industrial hemp. The products are mainly specialty papers such as cigarette paper[38], banknotes and technical filter papers[39] . Compared to wood pulp, hemp pulp offers a four to five times longer fibre, a significantly lower lignin fraction as well as a higher tear resistance and tensile strength. However, production costs are about four times higher than for paper from wood[40], so hemp paper could not be used for mass applications as printing, writing and packaging paper.
Topicals represent a newer emerging market in medical marijuana products geared toward health and beauty. Cannabinoids can be absorbed through the skin for certain therapeutic benefits without any psychoactivity. Additionally, the essential oils in hemp and cannabis provide many benefits for skin health. From moisturizers to shampoos and deodorants, medical cannabis products continue to diversify.
The first step to finding your correct CBD dosage is getting as much information as you can about the product you’re using. What is the concentration of CBD? Are there third-party lab tests that can confirm that? The CBD industry is still mainly a grassroots therapeutic movement, and as such, largely unregulated. Concentration and purity levels can differ greatly depending on the manufacturing process.

Another Israeli group postulated that the anti-inflammatory and immunosuppressive effects of CBD might make it a valuable adjunct in the treatment of acute graft-versus-host disease (GVHD) in patients who have undergone allogeneic hematopoietic stem cell transplantation. The authors investigated CBD 300 mg/d in addition to standard GVHD prophylaxis in 48 adult patients who had undergone transplantation predominantly for acute leukemia or myelodysplastic syndrome (NCT01385124 and NCT01596075).[21] The combination of CBD with standard GVHD prophylaxis was found to be safe. Compared with 101 historical controls treated with standard prophylaxis, patients who received CBD appeared to have a lower incidence of grade II to grade IV GVHD, suggesting that a randomized controlled trial (RCT) is warranted.
Cannabis smoke contains thousands of organic and inorganic chemical compounds. This tar is chemically similar to that found in tobacco smoke,[88] and over fifty known carcinogens have been identified in cannabis smoke,[89] including; nitrosamines, reactive aldehydes, and polycylic hydrocarbons, including benz[a]pyrene.[90] Cannabis smoke is also inhaled more deeply than is tobacco smoke.[91] As of 2015, there is no consensus regarding whether cannabis smoking is associated with an increased risk of cancer.[92] Light and moderate use of cannabis is not believed to increase risk of lung or upper airway cancer. Evidence for causing these cancers is mixed concerning heavy, long-term use. In general there are far lower risks of pulmonary complications for regular cannabis smokers when compared with those of tobacco.[93] A 2015 review found an association between cannabis use and the development of testicular germ cell tumors (TGCTs), particularly non-seminoma TGCTs.[94] A 2015 analysis of six studies found little evidence that long-term or regular cannabis smoking was associated with lung cancer risk, though it could not rule out whether an association with heavy smoking exists.[95] Another 2015 meta-analysis found no association between lifetime cannabis use and risk of head or neck cancer.[96] Combustion products are not present when using a vaporizer, consuming THC in pill form, or consuming cannabis foods.[97]

Marijuana, also called pot, weed, ganja, mary jane, and a host of other nicknames, is made from the Cannabis plant, which has three species: Cannabis sativa; Cannabis indica and Cannabis ruderalis. The flowering plant, which can grow to 16 feet (5 meters) high, likely originated in the Central Asian steppe, near the Altai or Tian Shian Mountains, and was first cultivated in China and India, according to "Cannabis and Cannabinoids: Pharmacology, Toxicology and Therapeutic Potential," (Routledge, 2002).


It sounds like the title of a children’s book, but like so much else that you learned in kindergarten, it’s true. Everyone’s body is different – but everyone’s endocannabinoid system is really unique. For reasons we don’t fully understand, receptors in the endocannabinoid system don’t respond predictably to cannabinoids from person to person. This lack of a predictable response makes standard dosing tricky.

The genus Cannabis was formerly placed in the nettle (Urticaceae) or mulberry (Moraceae) family, and later, along with the genus Humulus (hops), in a separate family, the hemp family (Cannabaceae sensu stricto).[44] Recent phylogenetic studies based on cpDNA restriction site analysis and gene sequencing strongly suggest that the Cannabaceae sensu stricto arose from within the former family Celtidaceae, and that the two families should be merged to form a single monophyletic family, the Cannabaceae sensu lato.[45][46]
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]

After revisions to cannabis scheduling in the UK, the government moved cannabis back from a class C to a class B drug. A purported reason was the appearance of high potency cannabis. They believe skunk accounts for between 70 and 80% of samples seized by police[153] (despite the fact that skunk can sometimes be incorrectly mistaken for all types of herbal cannabis).[154][155] Extracts such as hashish and hash oil typically contain more THC than high potency cannabis flowers.[156]

It often takes 10 to 15 years for the industry associated with a new agricultural crop to mature. While it is true that foreign imports have been the basis for hemp products in North America for at least a decade, North American production is only 4 years of age in Canada, and farming of hemp in the US has not even begun. Viewed from this perspective, the hemp industry in North America is still very much in its infancy. Varieties of hemp specifically suited to given products and regions have only started to be developed in North America. There is considerable uncertainty regarding yields, costs of production, harvesting and processing equipment, product characteristics, foreign competition, governmental support, and the vagaries of the regulatory environment. Hemp is not presently a standard crop, and is likely to continue experiencing the risks inherent in a small niche market for some time. Hemp is currently a most uncertain crop, but has such a diversity of possible uses, is being promoted by extremely enthusiastic market developers, and attracts so much attention that it is likely to carve out a much larger share of the North American marketplace than its detractors are willing to concede.

Canada is specialized on oilseed production and processing, so that hemp oil and grain are much more suitable than fiber. Because of the extensive development of oilseeds in Canada, there is extensive capacity to produce high-quality cold-pressed hemp oil. Canada in the last 5 years has made great advances in the growing, harvesting, and processing of hempseed, and indeed has moved ahead of the EU in the development of raw materials and products for the natural foods, nutraceuticals, and cosmetics industries. In the EU, a yield of 1 t/ha is considered good. In Canada, extraordinary yields of 1.5 t/ha have been realized, at least locally, although in the initial years of hempseed development in Canada yields were often less than 500 kg/ha. In 1999, the year of largest Canadian hemp acreage, yields averaged 900 kg/ha. (Ideally, hemp seed yield should be based on air dry weight—with about 12% moisture. Hemp yields are sometime uncertain, and could be exaggerated by as much as 50% when moist weights are reported.)
It is for this reason that all the finished hemp goods that you see for sale in America, from food products to clothing to building materials, are part of an imported hemp industry that has surpassed $688 million annually. The size of this import industry is one of the major catalysts for hemp legalization in the U.S. As a renewable source of a range of products, hemp provides an exciting new step in American agriculture.
The leaves, stems, flower buds and extracts from the marijuana plant can be eaten, brewed in a tea or put into a tincture. It can also be vaporized using an e-cigarette pen. Yale University researchers surveyed 3,847 Connecticut high school students about this practice in a 2015 study that was published in the journal Pediatrics. The study found nearly one in five e-cigarette users also have vaporize cannabis or byproducts like hash oil using the device. 
An industrial hemp license issued by the state provides authorization for the production of industrial hemp at a particular growing area by a particular individual or entity. Licenses will expire on the last day of December of the year that they are issued. Renewals do not require new fingerprinting unless the department requests it or if the corporate officers have changed.

CBD interacts with the body through the endogenous cannabinoid system (ECS) or endocannabinoid system. First discovered in the late 1980’s, the endocannabinoid system regulates the body’s homeostasis, or general state of balance, impacting such functions as mood, sleep, appetite, hormone regulation, and pain and immune response. Like an acrobat on a highwire, as the environment around us impacts our normal balance, the endocannabinoid system “corrects” by mediating our body’s reaction to keep us level.
Foreign sources, China in particular, can produce hemp seed cheaply, but imported seed must be sterilized, and the delays this usually requires are detrimental. Seed that has been sterilized tends to go rancid quickly, and so it is imperative that fresh seed be available, a great advantage for domestic production. An additional extremely significant advantage that domestic producers have over foreign sources is organic production, which is important for the image desired by the hemp food market. Organic certification is much more reliable in North America than in the foreign countries that offer cheap seeds. Whereas China used to supply most of the hempseed used for food in North America, Canadian-grown seeds have taken over this market.
Still, as the saying goes, absence of evidence isn’t necessarily evidence of absence, and there’s a reason we don’t have a ton of solid research on CBDs yet — “to study it, we need a good source, ” said Ziva Cooper, who is an associate professor at Columbia University and was on the National Academies committee. CBD is hard to get because it’s still technically a Schedule I drug, which limits its availability, Cooper said.

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.

Medical marijuana can soothe nausea and increase appetite, quiet pain, soothe anxiety and even reduce epileptic seizures. Other research on the healing effects of cannabis is being examined. For example, research suggests that THC may be able to improve memory according to a 2016 study on mice. More than half of the United States has legalized marijuana for medical use.
France is Europe's biggest producer (and the world's second largest producer) with 8,000 hectares cultivated.[80] 70-80% of the hemp fibre produced in 2003 was used for specialty pulp for cigarette papers and technical applications. About 15% was used in the automotive sector, and 5-6% was used for insulation mats. About 95% of hurds were used as animal bedding, while almost 5% was used in the building sector.[14] In 2010/2011, a total of 11,000 hectares (27,000 acres) was cultivated with hemp in the EU, a decline compared with previous year.[68][81]
Because C. sativa has been a neglected crop for so long in North America, there are only negligible genetic resources available on this continent. Most germplasm stocks of hemp are in Europe, and the largest and most important collection is the Vavilov Institute gene bank in Leningrad. Figure 11 shows THC concentrations in the Vavilov collection, as well as in our own collection, largely of European germplasm. A disturbingly high percentage of the collections have THC levels higher than 0.3%, making it difficult to incorporate these into breeding programs.

Hemp’s greatest obstacle is its association with psychoactive cannabis, despite the important distinction that hemp contains only nominal amounts (no more than 0.3%) of the psychoactive ingredient, tetrahydrocannabinol (THC). Although the U.S. is the largest importer of hemp products according to the Hemp Business Journal (a New Frontier Data subsidiary), hemp itself has struggled to gain social acceptance in the country and elsewhere. For instance, current U.S. legislation only permits universities and states performing agricultural or academic research to cultivate hemp. However, the 2018 Farm Bill currently in Congress would grant hemp full legalization across the nation. Passage of this bill would be a key step in promoting public acceptance in the U.S. and elsewhere, allowing the country to participate in the rapidly growing global hemp market.
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
No, as long as the plant is used correctly then no it’s not a bad thing. I’m sure there’s probably more good capability about that plant that people know or don’t know. No matter how it’s administered, as long as used properly it’s a good thing. It probably has more healing capabilities than people know about and since big Pharma or whoever it is out there discovered this, that’s probably why they made it illegal for all we know. Yes, I know there’s no money in cure which would hurt big Pharma but oh well! If they want to keep us away from the cure and keep us all sick, I say go for it anyway and go for the cure.
Cooper recently got funding from the National Institutes of Health for a study looking at cannabinoids — including CBD in isolation — as a substitute for opioids, and numerous other clinical trials of CBD are underway. It will be several years before results are available, but these studies should help clarify both what benefits the substance may provide and any side effects it may come with. Most of the adverse effects so far associated with cannabis, such as impairments in short-term memory, coordination and judgment,2 come from products that contain THC as well as CBD, Cooper said, but we need to do more studies to find out for sure whether CBD has fewer risks. Studies are also needed to identify the best way to administer and dose CBD. “I get emails from people asking me what dose of CBD to use, and the truth is, we really don’t know,” Cooper said.
Medical marijuana refers to the use of the Cannabis plant as a physician-recommended herbal therapy as well as synthetic[181] THC and cannabinoids. So far, the medical use of cannabis is legal only in a limited number of territories, including Canada,[37] Belgium, Australia, the Netherlands, Spain, and many U.S. states. This usage generally requires a prescription, and distribution is usually done within a framework defined by local laws. There is evidence supporting the use of cannabis or its derivatives in the treatment of chemotherapy-induced nausea and vomiting, neuropathic pain, and multiple sclerosis. Lower levels of evidence support its use for AIDS wasting syndrome, epilepsy, rheumatoid arthritis, and glaucoma.[74]
I have sporadic back spasms for year I see a chiropractor monthly for maintenance (it help) and deal with daily Knee & hip joint pain due to my job (heavy mechanic/steel work with lots of walking). after reading all the great reviews on CBD oil I want to get off the daily ibuprofen regiment and try CBD oil. I would like to try it as a gel cap but would like some advise on dosage size. I also want to know how often I should take the CBD treatments. any and all advise is appreciated
In an in vivo model using severe combined immunodeficient mice, subcutaneous tumors were generated by inoculating the animals with cells from human non-small cell lung carcinoma cell lines.[23] Tumor growth was inhibited by 60% in THC-treated mice compared with vehicle-treated control mice. Tumor specimens revealed that THC had antiangiogenic and antiproliferative effects. However, research with immunocompetent murine tumor models has demonstrated immunosuppression and enhanced tumor growth in mice treated with THC.[24,25]

Users have reported toxic symptoms, extreme reactions and serious psychological problems from using synthetic cannabis. These include: high blood, pressure, abdominal pain, nausea and vomiting, chest pain, heart palpitations, severe anxiety and paranoia, fear of dying, hallucinations, tremors and seizures, violent behaviour, and suicidal thoughts. These toxic symptoms have lasting several days and others have experienced long term mental health issues. Tolerance can develop quickly which means you will need more to get the same effect.
CBD may also enhance uptake of cytotoxic drugs into malignant cells. Activation of the transient receptor potential vanilloid type 2 (TRPV2) has been shown to inhibit proliferation of human glioblastoma multiforme cells and overcome resistance to the chemotherapy agent carmustine. [31] One study showed that coadministration of THC and CBD over single-agent usage had greater antiproliferative activity in an in vitro study with multiple human glioblastoma multiforme cell lines.[32] In an in vitro model, CBD increased TRPV2 activation and increased uptake of cytotoxic drugs, leading to apoptosis of glioma cells without affecting normal human astrocytes. This suggests that coadministration of CBD with cytotoxic agents may increase drug uptake and potentiate cell death in human glioma cells. Also, CBD together with THC may enhance the antitumor activity of classic chemotherapeutic drugs such as temozolomide in some mouse models of cancer.[13,33] A meta-analysis of 34 in vitro and in vivo studies of cannabinoids in glioma reported that all but one study confirmed that cannabinoids selectively kill tumor cells.[34]
Australia's National Cannabis Prevention and Information Centre (NCPIC) states that the buds (flowers) of the female cannabis plant contain the highest concentration of THC, followed by the leaves. The stalks and seeds have "much lower THC levels".[152] The UN states that leaves can contain ten times less THC than the buds, and the stalks one hundred times less THC.[149]
Given the uncertainties and handicaps associated with hemp, it is fortunate that there are compensating factors. As noted, as a crop hemp offers some real environmental advantages, particularly with regard to the limited needs for herbicides and pesticides. Hemp is therefore pre-adapted to organic agriculture, and accordingly to the growing market for products associated with environmentally-friendly, sustainable production. Hemp products are an advertiser’s dream, lending themselves to hyperbole (“healthiest salad oil in the world,” “toughest jeans on the market”). While the narcotics image of C. sativa is often disadvantageous, advertisers who choose to play up this association do so knowing that it will attract a segment of the consuming population. In general, the novelty of hemp means that many consumers are willing to pay a premium price. It might also be said that those who have entered the hemp industry have tended to be very highly motivated, resourceful, and industrious, qualities that have been needed in the face of rather formidable obstacles to progress.
A CNN program that featured Charlotte's Web cannabis in 2013 brought increased attention to the use of CBD in the treatment of seizure disorders.[68][69] Since then, 16 states have passed laws to allow the use of CBD products with a doctor's recommendation (instead of a prescription) for treatment of certain medical conditions.[70] This is in addition to the 30 states that have passed comprehensive medical cannabis laws, which allow for the use of cannabis products with no restrictions on THC content.[70] Of these 30 states, eight have legalized the use and sale of cannabis products without requirement for a doctor's recommendation.[70]

After seasonal harvests of specific cultivars, these high-CBD hemp crops are put through a specialized solvent-free extraction process to yield a hemp oil that is naturally high in cannabidiol. This pure hemp extract is then tested for safety, quality, and cannabinoid content before being exported to our processing facilities in the United States. Importing any cannabis or hemp product into the United States is a complicated and serious task, so we leave nothing to chance before our high-CBD hemp oil makes its journey across the Atlantic Ocean.

Let's start with the most officially proven medical use of CBD. Earlier this year, the FDA approved the first-ever drug containing CBD, Epidiolex, to treat two rare forms of pediatric epilepsy. To get to that point, the drug's manufacturers had to do a whole lot of randomized, placebo-controlled trials on humans. They had to study how much children could take, what would happen in case of overdose, and any possible side effects that would occur.

More recently, Sakamoto and various co-authors[34][35] have used RAPD to isolate several genetic marker sequences that they name Male-Associated DNA in Cannabis (MADC), and which they interpret as indirect evidence of a male chromosome. Several other research groups have reported identification of male-associated markers using RAPD and AFLP.[36][24][37] Ainsworth commented on these findings, stating,

We gave the highest points to companies that use a CBD distillate for their tinctures. The process of distillation creates an extract that is pure on a molecular level. There are people who think distillate is too pure, and that a full spectrum decarb produces a more effective tincture. But in light of the inconclusive evidence, we prefer a distillate. The process allows for a high degree of control as to the finished product. It’s also odorless and tasteless, so those tinctures tend to taste better.
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.
The arrival of Epidiolex is unlikely to erase the unregulated CBD market, however. For one, Epidiolex has been studied only in connection with a small number of epileptic conditions. If and when Epidiolex makes its way to drug stores, it will be approved only for the treatment of Dravet Syndrome and Lennox-Gastaut Syndrome, two rare forms of catastrophic epilepsy. People like me, with comparatively mild Janz Syndrome, and people like Harper, with extremely rare conditions like CDKL5, may still be out of luck.
The endocannabinoid system is believed to be centrally involved in the regulation of mood and the extinction of aversive memories. Animal studies have shown CBD to have anxiolytic properties. It was shown in rats that these anxiolytic properties are mediated through unknown mechanisms.[52] Anxiolytic effects of CBD have been shown in several animal models.[53,54]
Until recent times, the cultivation of hemp primarily as an oilseed was largely unknown, except in Russia. Today, it is difficult to reconstruct the type of plant that was grown there as an oilseed, because such cultivation has essentially been abandoned. Oilseed hemp cultivars in the modern sense were not available until very recently, but some land races certainly were grown specifically for seeds in Russia. Dewey (1914) gave the following information: “The short oil-seed hemp with slender stems, about 30 inches high, bearing compact clusters of seeds and maturing in 60 to 90 days, is of little value for fiber production, but the experimental plants, grown from seed imported from Russia, indicate that it may be valuable as an oil-seed crop to be harvested and threshed in the same manner as oil-seed flax.” Most hemp oilseed in Europe is currently obtained from so-called “dual usage” plants (employed for harvest of both stem fiber and seeds, from the same plants). Of the European dual-usage cultivars, ‘Uniko B’ and ‘Fasamo’ are particularly suited to being grown as oilseeds. Very recently, cultivars have been bred specifically for oilseed production. These include ‘Finola,’ formerly known as ‘Fin-314’ (Fig. 6) and ‘Anka’ (Fig. 7), which are relatively short, little-branched, mature early in north-temperate regions, and are ideal for high-density planting and harvest with conventional equipment. Dewey (1914) noted that a Turkish narcotic type of land race called “Smyrna” was commonly used in the early 20th century in the US to produce birdseed, because (like most narcotic types of Cannabis) it is densely branched, producing many flowers, hence seeds. While oilseed land races in northern Russia would have been short, early-maturing plants in view of the short growing season, in more southern areas oilseed landraces likely had moderate height, and were spaced more widely to allow abundant branching and seed production to develop. Until Canada replaced China in 1998 as a source of imported seeds for the US, most seeds used for various purposes in the US were sterilized and imported from China. Indeed, China remains the largest producer of hempseed. We have grown Chinese hemp land races, and these were short, branched, adapted to a very long growing season (i.e. they come into flower very slowly in response to photoperiodic induction of short days in the fall), and altogether they were rather reminiscent of Dewey’s description of Smyrna. Although similar in appearance to narcotic strains of C. sativa, the Chinese land races we grew were in fact low in intoxicating constituents, and it may well be that what Dewey thought was a narcotic strain was not. Although some forms of C. sativa have quite large seeds, until recently oilseed forms appear to have been mainly selected for a heavy yield of seeds, usually recognizable by abundant branching. Such forms are typically grown at lower densities than hemp grown only for fiber, as this promotes branching, although it should be understood that the genetic propensity for branching has been selected. Percentage or quality of oil in the seeds does not appear to have been important in the past, although selection for these traits is now being conducted. Most significantly, modern selection is occurring with regard to mechanized harvesting, particularly the ability to grow in high density as single-headed stalks with very short branches bearing considerable seed.
Over the past two years, 17 states have passed laws legalizing CBD so that patients can obtain the drug without fear of prosecution from local authorities. For intractable childhood epilepsies—the sorts of seizure disorders that for centuries have ruined lives and shattered families, the ones even specialists like Hernandez dread—CBD could be a miracle cure.
The earliest recorded uses date from the 3rd millennium BC.[32] Since the early 20th century, cannabis has been subject to legal restrictions. The possession, use, and sale of cannabis is illegal in most countries of the world.[33][34] Medical cannabis refers to the physician-recommended use of cannabis, which takes place in Canada, Belgium, Australia, the Netherlands, Germany, Spain, and 31 U.S. states.[35] In September 2018 cannabis was legalized in South Africa[36] while Canada legalized recreational use of cannabis in October 2018.[37]

From the 1950s to the 1980s, the Soviet Union was the world's largest producer of hemp (3,000 km2 in 1970). The main production areas were in Ukraine,[82] 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.[83][84]
