Under federal law, cannabis (from which both CBD and marijuana are derived) is illegal everywhere, although the laws against it aren’t generally enforced in states that have legalized marijuana. Some manufacturers claim that CBD culled from legally imported industrial hemp, which has little to no THC, is fine to ship across the U.S., but many experts disagree, noting that because hemp comes from the same species as marijuana, cannabis sativa, all CBD falls under the DEA’s Schedule 1 designation. “This creative interpretation of the law runs afoul of reality,” says the Brookings Institution, a Washington, DC, think tank.
As detailed below, the development of hemp as a new legal crop in North America must be considered in relation to illicit cultivation, so it is important to appreciate the scope of the drug situation. Up until the first half of the 20th century, drug preparations of Cannabis were used predominantly as a recreational inebriant in poor countries and the lower socio-economic classes of developed nations. After World War II, marijuana became associated with the rise of a hedonistic, psychedelic ethos, first in the United States and eventually over much of the world, with the consequent development of a huge international illicit market that exceeds the value of the hemp market during its heyday. Table 3 shows the “economic significance” (dollars generated in the black market plus dollar cost of control measures) of the illicit drug industry associated with C. sativa, and contrasts this with the estimated dollar value of major categories of legitimate uses. In the Netherlands, the annual value of narcotic hemp cultivation (ca. $10 billion) exceeds the value of tulips (Collins 1999). Marijuana has become the most widely disseminated illicit species in the world (Schultes and Hofmann 1980). With the exception of alcohol, it is the most widely used recreational euphoric drug. About 25% of North Americans are believed to have used Cannabis illegally. According to the US National Institute on Drug Abuse (www.nida.nih.gov/Infofax/marijuana.html), more than 72 million Americans (33%) 12 years of age and older have tried marijuana. Cultivation, commerce, and consumption of drug preparations of Cannabis have been proscribed in most countries during the present century. The cost of enforcing the laws against Cannabis in North America is in the billions of dollars annually. In addition, there are substantial social costs, such as adverse effects on users, particularly those who are convicted. Tragically this includes some legitimate farmers who, faced with financial ruin because of the unprofitability of crops being grown, converted to growing marijuana.
In 1924, Russian botanist D.E. Janichevsky concluded that ruderal Cannabis in central Russia is either a variety of C. sativa or a separate species, and proposed C. sativa L. var. ruderalis Janisch, and Cannabis ruderalis Janisch, as alternative names. In 1929, renowned plant explorer Nikolai Vavilov assigned wild or feral populations of Cannabis in Afghanistan to C. indica Lam. var. kafiristanica Vav., and ruderal populations in Europe to C. sativa L. var. spontanea Vav. In 1940, Russian botanists Serebriakova and Sizov proposed a complex classification in which they also recognized C. sativa and C. indica as separate species. Within C. sativa they recognized two subspecies: C. sativa L. subsp. culta Serebr. (consisting of cultivated plants), and C. sativa L. subsp. spontanea (Vav.) Serebr. (consisting of wild or feral plants). Serebriakova and Sizov split the two C. sativa subspecies into 13 varieties, including four distinct groups within subspecies culta. However, they did not divide C. indica into subspecies or varieties.

Cannabis Ruderalis – Thought to be a cannabis species originating in central Asia, it flowers earlier, is much smaller, and can withstand much harsher climates than either Cannabis indica or Cannabis sativa. This species purportedly buds based on age rather than changes in length of daylight, known as auto-flowering. It’s used primarily for food production, such as hemp seeds and hemp seed oil.
In 1972, the Dutch government divided drugs into more- and less-dangerous categories, with cannabis being in the lesser category. Accordingly, possession of 30 grams or less was made a misdemeanor. Cannabis has been available for recreational use in coffee shops since 1976. Cannabis products are only sold openly in certain local "coffeeshops" and possession of up to 5 grams for personal use is decriminalised, however: the police may still confiscate it, which often happens in car checks near the border. Other types of sales and transportation are not permitted, although the general approach toward cannabis was lenient even before official decriminalisation.
Harper was diagnosed as an infant with CDKL5, a rare genetic condition doctors only discovered in 2004 and that afflicts roughly 600 people worldwide. The disorder shares its name with the minute particle of DNA it affects, a gene responsible for the production of a protein crucial for neurological development. Symptoms of CDKL5 include intellectual disability, developmental delays, breathing and vision problems, limited or absent speech, poor muscle tone, and, perhaps worst of all, frequent seizures.
Food and beverage products containing CBD were introduced in the United States in 2017. Similar to energy drinks and protein bars which may contain vitamin or herbal additives, food and beverage items can be infused with CBD as an alternative means of ingesting the substance. In the United States, numerous products are marketed as containing CBD, but in reality contain little or none. Some companies marketing CBD-infused food products with claims that are similar to the effects of prescription drugs have received warning letters from the Food and Drug Administration for making unsubstantiated health claims.
Cannabis is predominantly dioecious, having imperfect flowers, with staminate "male" and pistillate "female" flowers occurring on separate plants. "At a very early period the Chinese recognized the Cannabis plant as dioecious", and the (c. 3rd century BCE) Erya dictionary defined xi 枲 "male Cannabis" and fu 莩 (or ju 苴) "female Cannabis". Male flowers are normally borne on loose panicles, and female flowers are borne on racemes.
Breeding for low THC cultivars in Europe has been reviewed by Bócsa (1998), Bócsa and Karus (1998), and Virovets (1996). Some researchers have claimed to have produced essentially THC-free strains, although at present no commercial cultivar seems to be 100% free of THC. THC content has proven to be more easily reduced in monoecious than in dioecious varieties. It should be possible to select THC-free strains, and there has been speculation that genetic engineering could be helpful in this regard. As a strategic economic and political tactic, France has been attempting for several years to have the European Union (EU) adopt legislation forbidding the cultivation of industrial hemp cultivars with more than 0.1% THC, which would mean that primarily French varieties would have to be cultivated in Europe. However, the Canadian government has found that some French material has proven to be excessively high in THC.
In 2015, almost half of the people in the United States had tried marijuana, 12% had used it in the past year, and 7.3% had used it in the past month. In 2014, daily marijuana use amongst US college students had reached its highest level since records began in 1980, rising from 3.5% in 2007 to 5.9% in 2014 and had surpassed daily cigarette use.
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.
Cannabinoids may cause antitumor effects by various mechanisms, including induction of cell death, inhibition of cell growth, and inhibition of tumor angiogenesis invasion and metastasis.[9-12] Two reviews summarize the molecular mechanisms of action of cannabinoids as antitumor agents.[13,14] Cannabinoids appear to kill tumor cells but do not affect their nontransformed counterparts and may even protect them from cell death. For example, these compounds have been shown to induce apoptosis in glioma cells in culture and induce regression of glioma tumors in mice and rats, while they protect normal glial cells of astroglial and oligodendroglial lineages from apoptosis mediated by the CB1 receptor.
Fiberboard. In North America the use of nonwood fibers in sheet fiberboard (“pressboard” or “composite board”) products is relatively undeveloped. Flax, jute, kenaf, hemp, and wheat straw can be used to make composite board. Wheat straw is the dominant nonwood fiber in such applications. Although it might seem that hemp bast fibers are desirable in composite wood products because of their length and strength, in fact the short fibers of the hurds have been found to produce a superior product (K. Domier, pers. commun.). Experimental production of hemp fiberboard has produced extremely strong material (Fig. 22). The economic viability of such remains to be tested. Molded fiberboard products are commercially viable in Europe (Fig. 23), but their potential in North America remains to be determined.
CBD is a safe, long-term aid which is why it has gained such momentum and why our customers are turning to it for relief. CBD, scientifically known as cannabidiol, is a non-psychoactive, organic compound found in the hemp plant. When it interacts with the body’s endocannabinoid system, CBD provides powerful health benefits without the side effects of conventional drugs.
The high absorbency of hemp hurds has led to their occasional use as an absorbent for oil and waste spill cleanup. Hemp as an industrial absorbent has generated some interest in Alberta, for use in land reclamation in the oil and gas industry. Because hemp hurds are a costly product, it is likely that animal bedding will remain the most important application.
Because of its high THC-content, in most parts of the world, including the US, Marijuana is illegal. Seeing the massive economical and medicinal benefits that Marijuana can provide, some countries and states in the US have legalized Marijuana. As the political landscape changes, hopefully more will follow, but as of now, Marijuana is generally illegal.
In a randomized clinical trial, researchers compared the safety and effectiveness of orally administered Cannabis extract (2.5 mg THC and 1 mg CBD), THC (2.5 mg), or placebo for the treatment of cancer-related anorexia-cachexia in 243 patients with advanced cancer who received treatment twice daily for 6 weeks. Results demonstrated that although these agents were well tolerated by these patients, no differences were observed in patient appetite or quality of life among the three groups at this dose level and duration of intervention.
To illustrate how hemp programs can wither without proper support, she pointed to California, where regulators continue struggling to keep up with rules and infrastructure for the more potent (and popular) marijuana industry, from lab tests to license approvals; the state's hemp operators, meanwhile, are still waiting for their official license application to come out.
Hemp, the non-psychoactive variety of the cannabis sativa plant, is already being integrated into several mature markets such as food, textiles, construction, personal care and nutraceuticals. This relatively quiet cannabis relative is emerging as a potential commodity ripe to not only impact, but possibly revolutionize, tech-driven markets and economies around the world.
Selection for fiber has resulted in strains that have much more bark fiber tissues and much less woody core than encountered in narcotic strains, oilseed strains, and wild plants (Fig. 12). In non-fiber strains of Cannabis, bark can be less than one quarter of the stem tissues (i.e. more than three quarters can be woody core). By contrast, in fiber strains half of the stem tissues can be bark, and more than half of this can be the desirable long primary fibers (de Meijer 1995). Non-fiber strains rarely have as much as 15% fiber in the bark.

Donald Abrams was a member of the committee that reviewed the evidence that went into producing the report, and he said that the studies they reviewed overwhelmingly used pharmaceutically available preparations that contain THC, including dronabinol, nabilone and the whole-plant extract spray nabiximols, which contains equal parts CBD and THC. It’s impossible to know whether the benefits of cannabis can also be obtained from CBD alone, Abrams said, because CBD is just one of 400 chemicals present in the plant. So far, CBD in isolation has been studied in only a handful of randomized, placebo-controlled trials (considered the gold standard of evidence in medical research), and the evidence remains sparse.
"The dairy industry is really in trouble, and so, one of the things that I find really important is finding value-added products," Gilbert Jenkins said. "I am not an et. al scientist, I am not a dairy farmer, but I know about the crops that they grow. Having an opportunity to grow a crop -- even on just a portion of the acres -- that could bring in new income."
More recently, Sakamoto and various co-authors 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. Ainsworth commented on these findings, stating,
Jump up ^ Juliet Eilperin (February 11, 2013), "'Good seed' versus 'evil weed': Hemp activists eye legalization", The Washington Post – via The Japan Times Online, [A] couple of factors — the high taxes the federal government imposed on growing hemp in the late 1930s and again in the early '50s, and then the DEA's interpretation of the 1970 law — made producing hemp nearly impossible. Since the DEA only grants permits in rare instances and demands costly, elaborate security precautions, large-scale hemp growing in the United States is not viable.
There are ways to strain dangerous contaminants out of raw hemp paste. And most companies stand behind their quality and safety procedures. “We continuously test all our products ... to ensure our consumers get the levels of natural constituents they expect from the quality hemp stalk oil they purchase,” HempMedsPx states on its web site. “Additionally, all our products are tested for safety, to ensure there are no solvents, heavy metals, or other potentially harmful materials in our oil. Because we take these steps, we are always confident in our products, and you can be too.”
Several of the cannabinoids are reputed to have medicinal potential: THC for glaucoma, spasticity from spinal injury or multiple sclerosis, pain, inflammation, insomnia, and asthma; CBD for some psychological problems. The Netherlands firm HortaPharm developed strains of Cannabis rich in particular cannabinoids. The British firm G.W. Pharmaceuticals acquired proprietary access to these for medicinal purposes, and is developing medicinal marijuana. In the US, NIH (National Institute of Health) has a program of research into medicinal marijuana, and has supplied a handful of individuals for years with maintenance samples for medical usage. The American Drug Enforcement Administration is hostile to the medicinal use of Cannabis, and for decades research on medicinal properties of Cannabis in the US has been in an extremely inhospitable climate, except for projects and researchers concerned with curbing drug abuse. Synthetic preparations of THC—dronabinol (Marinol®) and nabilone (Cesamet®)—are permitted in some cases, but are expensive and widely considered to be less effective than simply smoking preparations of marijuana. Relatively little material needs to be cultivated for medicinal purposes (Small 1971), although security considerations considerably inflate costs. The potential as a “new crop” for medicinal cannabinoid uses is therefore limited. However, the added-value potential in the form of proprietary drug derivatives and drug-delivery systems is huge. The medicinal efficacy of Cannabis is extremely controversial, and regrettably is often confounded with the issue of balancing harm and liberty concerning the proscriptions against recreational use of marijuana. This paper is principally concerned with the industrial uses of Cannabis. In this context, the chief significance of medicinal Cannabis is that, like the issue of recreational use, it has made it very difficult to rationally consider the development of industrial hemp in North America for purposes that everyone should agree are not harmful.
Because cannabinoid receptors, unlike opioid receptors, are not located in the brainstem areas controlling respiration, lethal overdoses from Cannabis and cannabinoids do not occur.[1-4] However, cannabinoid receptors are present in other tissues throughout the body, not just in the central nervous system, and adverse effects include tachycardia, hypotension, conjunctival injection, bronchodilation, muscle relaxation, and decreased gastrointestinal motility.
All this talk about THC lands us nicely in the whole “Full Spectrum vs. Pure Isolate” debate. Once you begin shopping for CBD products, you’ll notice a lot of jargon that gets thrown around without much explanation. Now that we’ve introduced THC into the conversation, we can talk about the difference between, and relative benefits of, Full Spectrum CBD and CBD Isolate (and the lesser-known contender: Broad Spectrum).
Unlike other Cannabis sativa varieties and hybrids, which are mostly grown for their chemically potent flowers (or 'buds'), hemp is also legally distinguished from marijuana in the US as containing less than 0.3% of the cannabinoid chemical THC — considered to be the most intoxicating, psychoactive component in cannabis plants, as well as a treatment option for certain serious illnesses.
Several studies have demonstrated the therapeutic effects of cannabinoids for nausea and vomiting in the advanced stages of illnesses such as cancer and AIDS. Dronabinol (tetrahydrocannabinol) has been available by prescription for more than a decade in the USA. Other therapeutic uses of cannabinoids are being demonstrated by controlled studies, including treatment of asthma and glaucoma, as an antidepressant, appetite stimulant, anticonvulsant and anti-spasmodic, research in this area should continue. For example, more basic research on the central and peripheral mechanisms of the effects of cannabinoids on gastrointestinal function may improve the ability to alleviate nausea and emesis. More research is needed on the basic neuropharmacology of THC and other cannabinoids so that better therapeutic agents can be found.
An analysis of 84,170 participants in the California Men’s Health Study was performed to investigate the association between Cannabis use and the incidence of bladder cancer. During 16 years of follow-up, 89 Cannabis users (0.3%) developed bladder cancer compared with 190 (0.4%) of the men who did not report Cannabis use (P < .001). After adjusting for age, race, ethnicity, and body mass index, Cannabis use was associated with a 45% reduction in bladder cancer incidence (hazard ratio, 0.55; 95% confidence interval, 0.33–1.00).
The above uses are based on hemp as a mechanical strengthener of materials. Hemp can also be chemically combined with materials. For example, hemp with gypsum and binding agents may produce light panels that might compete with drywall. Hemp and lime mixtures make a high quality plaster. Hemp hurds are rich in silica (which occurs naturally in sand and flint), and the hurds mixed with lime undergo mineralization, to produce a stone-like material. The technology is most advanced in France (Fig. 26). The mineralized material can be blown or poured into the cavities of walls and in attics as insulation. The foundations, walls, floors, and ceilings of houses have been made using hemp hurds mixed with natural lime and water. Sometimes plaster of Paris (pure gypsum), cement, or sand is added. The resulting material can be poured like concrete, but has a texture vaguely reminiscent of cork—much lighter than cement, and with better heat and sound-insulating properties. An experimental “ceramic tile” made of hemp has recently been produced (Fig. 27).
A chief argument that has been advanced in favor of developing hemp as a paper and pulp source has been that as a non-wood or tree-free fiber source, it can reduce harvesting of primary forests and the threat to associated biodiversity. It has been claimed that hemp produces three to four times as much useable fiber per hectare per annum as forests. However, Wong (1998) notes evidence that in the southern US hemp would produce only twice as much pulp as does a pine plantation (but see discussion below on suitability of hemp as a potential lumber substitute in areas lacking trees).

Hi Marilyn, I would recommend a topical lotion or salve to start for instant relief.. Maybe 250 to 300 mg tincture to see how you feel. For me, the salve took the pain in my hands away in under a minute. I didn't notice how much the tincture worked until I forgot to take on vacation. Pain that was pretty much gone but came back, I was tired, grumpy and felt horrible. It works, just need to find right product and dosage for you.
Medical reviews published in 2017 and 2018 incorporating numerous clinical trials concluded that cannabidiol is an effective treatment for certain types of childhood epilepsy. An orally administered cannabidiol solution (brand name Epidiolex) was approved by the US Food and Drug Administration in June 2018 as a treatment for two rare forms of childhood epilepsy, Lennox-Gastaut syndrome and Dravet syndrome.
The dosages mentioned do not take into account the strength of the tincture. I have Elixinol 300, I took 1/2 dropper (0.5ml, which offers 5mg of CBD) as indicated on the bottle and felt severely nauseous for 3 hours thereafter. There is no way I cold take this dose twice per day, as recommended on the bottle. The high dosages on this site must surely be for much weaker concentrations?
Another clinical trial that involved 139 patients with HIV or AIDS and weight loss found that, compared with placebo, oral dronabinol was associated with a statistically significant increase in appetite after 4 to 6 weeks of treatment. Patients receiving dronabinol tended to have weight stabilization, whereas patients receiving placebo continued to lose weight.
CBD vaporizer oils can be used in a vaporizer of your choice. They offer a healthy way of inhaling your daily dose of the CBD supplement. Vaping is a very direct way of ingesting CBD oil. When you vape, the CBD enters the lungs and goes directly into the bloodstream, completely bypassing the digestive system. This method allows for greater bioavailability.
The Department has policies and procedures in place for the commonwealth's hemp research program, which can be found in the 2019 Pilot Program Parameters. Researchers from institutions of higher education or growers who would like to be considered for participation in the 2019 program must submit a 2019 PDA Industrial Hemp Research Pilot Program Permit Application prior to the application deadline of December 17, 2018. Researchers who participated in the 2018 Pilot Program may submit a Permit Renewal form by December 17, 2018 to continue their projects in the 2019 growing season.
Marijuana and hemp both come from the same species of plant, Cannabis sativa. Once it was discovered the plant’s flowers can can have psychoactive effects, cultivators began growing separate strains of the plant – one normal variety, and one whose flowers contained higher levels of the cannabinoid tetrahydrocannabinol (THC), leading to tighter regulation.
The plant is also known as hemp, although this term is often used to refer only to varieties of Cannabis cultivated for non-drug use. Cannabis has long been used for hemp fibre, for hemp oils, for medicinal purposes, and as a recreational drug. Industrial hemp products are made from cannabis plants selected to produce an abundance of fiber. To satisfy the UN Narcotics Convention, some cannabis strains have been bred to produce minimal levels of tetrahydrocannabinol (THC), the principal psychoactive constituent. Some strains have been selectively bred to produce a maximum of THC (a cannabinoid), the strength of which is enhanced by curing the flowers. Various compounds, including hashish and hash oil, are extracted from the plant.
Can CBD oil help anxiety? Cannabidiol (CBD) is a chemical occurring in cannabis plants. It is possible to add CBD oil to food, and an increasing amount of evidence suggests that it may improve mental health, particularly anxiety. It does not seem to have adverse side effects, but CBD oil is illegal in some states. Learn more about CBD oil here. Read now
In Buddhism, cannabis is generally regarded as an intoxicant and may be a hindrance to development of meditation and clear awareness. In ancient Germanic culture, Cannabis was associated with the Norse love goddess, Freya. An anointing oil mentioned in Exodus is, by some translators, said to contain Cannabis. Sufis have used Cannabis in a spiritual context since the 13th century CE.
Specific city and county laws have been enacted to regulate how citizens and tourists may possess and consume marijuana. Penalties exist for driving while under the influence of marijuana. Someone driving under the influence of marijuana is considered impaired in both Colorado and Washington when five nanograms per milliliter (ng/mL) of blood or more of active THC is detected.
The plant was first given its taxonomic identification by Carl Linnaeus in 1753 and thoroughly described to Westerners in the 1800s, when the medical doctor William O'Shaughnessy gave a report to the Medical and Physical Society of Calcutta in India in 1839. The doctor described its effects on people and did a few case reports on "gunjah," the Indian name for the drug.
Hemp is possibly one of the earliest plants to be cultivated. An archeological site in the Oki Islands near Japan contained cannabis achenes from about 8000 BC, probably signifying use of the plant. Hemp use archaeologically dates back to the Neolithic Age in China, with hemp fiber imprints found on Yangshao culture pottery dating from the 5th millennium 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.
