Many governments view occupational health as a social challenge and have formed public organizations to ensure the health and safety of workers. Examples of these include the British Health and Safety Executive and in the United States, the National Institute for Occupational Safety and Health, which conducts research on occupational health and safety, and the Occupational Safety and Health Administration, which handles regulation and policy relating to worker safety and health.[63][64][65]

The problem is, it’s not easy to know what you’re actually ingesting, or if it’ll actually change how you feel. At best, CBD in America exists in a confusing state of quasi-legality and yet-to-be-realized potential. Experts estimate that the market for it could balloon to $22 billion by 2022, but with cannabis and hemp laws changing rapidly across the country, the chemical is almost entirely unregulated on the consumer market, with no end-product labeling or composition standards to help shoppers understand what they’re buying.
"Probably indigenous to temperate Asia, C. sativa is the most widely cited example of a “camp follower.” It was pre-adapted to thrive in the manured soils around man’s early settlements, which quickly led to its domestication (Schultes 1970). Hemp was harvested by the Chinese 8500 years ago (Schultes and Hofmann 1980). For most of its history, C. sativa was most valued as a fiber source, considerably less so as an intoxicant, and only to a limited extent as an oilseed crop. Hemp is one of the oldest sources of textile fiber, with extant remains of hempen cloth trailing back 6 millennia. Hemp grown for fiber was introduced to western Asia and Egypt, and subsequently to Europe somewhere between 1000 and 2000 BCE. Cultivation in Europe became widespread after 500 CE. The crop was first brought to South America in 1545, in Chile, and to North America in Port Royal, Acadia in 1606. The hemp industry flourished in Kentucky, Missouri, and Illinois between 1840 and 1860 because of the strong demand for sailcloth and cordage (Ehrensing 1998). From the end of the Civil War until 1912, virtually all hemp in the US was produced in Kentucky."
The high lipid-solubility of cannabinoids results in their persisting in the body for long periods of time.[140] Even after a single administration of THC, detectable levels of THC can be found in the body for weeks or longer (depending on the amount administered and the sensitivity of the assessment method).[140] A number of investigators have suggested that this is an important factor in marijuana's effects, perhaps because cannabinoids may accumulate in the body, particularly in the lipid membranes of neurons.[141]

According to Delphic analysis by British researchers in 2007, cannabis has a lower risk factor for dependence compared to both nicotine and alcohol.[98] However, everyday use of cannabis may be correlated with psychological withdrawal symptoms, such as irritability or insomnia,[94] and susceptibility to a panic attack may increase as levels of THC metabolites rise.[99][100] However, cannabis withdrawal symptoms are typically mild and are never life-threatening.[101]


In September 2005, New Scientist reported that researchers at the Canberra Institute of Technology had identified a new type of Cannabis based on analysis of mitochondrial and chloroplast DNA.[81] The New Scientist story, which was picked up by many news agencies and web sites, indicated that the research was to be published in the journal Forensic Science International.[82]
"Beginning around 1995, an increasing number of state legislatures began to consider a variety of initiatives related to industrial hemp. Most of these have been resolutions calling for scientific, economic, or environmental studies, and some are laws authorizing planting experimental plots under state statutes. Nonetheless, the actual planting of hemp, even for state-authorized experimental purposes, remains regulated by DEA under the CSA.
Fresh Nature Hemp CBD Oil is quickly absorbed into the bloodstream to trigger a positive inflammatory and stress response. We highly recommend to use it to get relief from all forms of aches and pains. In the long run, it also help support joint health & mobility. Fresh Nature Hemp was an easy pick for our #1 choice, no other CBD oil was able to treat pain in our tests better than Fresh Nature Hemp CBD.
The basic commercial options for growing hemp in North America is as a fiber plant, an oilseed crop, or for dual harvest for both seeds and fiber. Judged on experience in Canada to date, the industry is inclined to specialize on either fiber or grain, but not both. Hemp in our opinion is particularly suited to be developed as an oilseed crop in North America. The first and foremost breeding goal is to decrease the price of hempseed by creating more productive cultivars. While the breeding of hemp fiber cultivars has proceeded to the point that only slight improvements can be expected in productivity in the future, the genetic potential of hemp as an oilseed has scarcely been addressed. From the point of view of world markets, concentrating on oilseed hemp makes sense, because Europe has shown only limited interest to date in developing oilseed hemp, whereas a tradition of concentrating on profitable oilseed products is already well established in the US and Canada. Further, China’s supremacy in the production of high-quality hemp textiles at low prices will be very difficult to match, while domestic production of oilseeds can be carried out using technology that is already available. The present productivity of oilseed hemp—about 1 t/ha under good conditions, and occasional reports of 1.5 to 2 t/ha, is not yet sufficient for the crop to become competitive with North America’s major oilseeds. We suggest that an average productivity of 2 t/ha will be necessary to transform hempseed into a major oilseed, and that this breeding goal is achievable. At present, losses of 30% of the seed yields are not uncommon, so that improvements in harvesting technology should also contribute to higher yields. Hemp food products cannot escape their niche market status until the price of hempseed rivals that of other oilseeds, particularly rapeseed, flax, and sunflower. Most hemp breeding that has been conducted to date has been for fiber characteristics, so that there should be considerable improvement possible. The second breeding goal is for larger seeds, as these are more easily shelled. Third is breeding for specific seed components. Notable are the health-promoting gamma-linolenic acid; improving the amino acid spectrum of the protein; and increasing the antioxidant level, which would not only have health benefits but could increase the shelf life of hemp oil and foods.

Hi, I had ovarian cancer stage 2 and went to do chemotherapy for 16 times in 2014. It came back last year 2016 but I did not do chemotherapy or radiation therapy as suggested by the doctor. I am taking hormone therapy at the moment. I would like to use cannabis oil but which one and how much CBD and how much THC should I take for ovarian cancer? Can anyone give some idea?. Thank you very much.
The important thing is that you have to be SUPER careful when selecting CBD oils. Since the cannabis industry is not FDA-regulated, there have been dozens and dozens of companies trying to get away with selling very low quality (and even potentially toxic), “snake oils” that have been extracted using harsh chemical solvents like butane and hexane. Make sure you stay away from cheap products like these, as they could damage your health.
Hemp fibers are primarily used for textiles, paper, building materials, and other industrial products. Hurds, or shives, are short woody hemp fibers typically found inside the stalk. They’re used to make hempcrete, bedding materials, absorbents, particle board, ceiling panels, compost, and other industrial products. Bast fibers make up the outer portion of the stalk and are typically split into three categories — primary, or line fiber, secondary, and the tow. They are categorized according to their cell strength and cell wall thickness, which will determine the fiber’s strength, durability, and ultimately what the it can be used for.
In a Phase II double-blind, randomized, placebo-controlled, 5-week study of 56 rheumatoid arthritis patients with Sativex (Blake et al 2006), employed nocturnal treatment only to a maximum of 6 sprays per evening (16.2 mg THC + 15 mg CBD). In the final treatment week, morning pain on movement, morning pain at rest, DAS-28 measure of disease activity, and SF-MPQ pain at present all favored Sativex over placebo (Table 1).
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.
Although hemp can be successfully grown continuously for several years on the same land, rotation with other crops is desirable. A 3- or preferably 4-year rotation may involve cereals, clover or alfalfa for green manure, maize, and hemp. In Ontario it has been recommended that hemp not follow canola, edible beans, soybeans or sunflowers. However, according to Bócsa and Karus (1998), “it matters little what crops are grown prior to hemp.”
CBD is able to reduce inflammation in the body by limiting re-uptake of the neurotransmitter adenosine. CBD does this, in part, by inhibiting equilibrative nucleoside transporter 1 (ENT1). By slowing its re-uptake, the amount of adenosine in the brain is increased which in turn impacts the activity of adenosine receptors.  These receptors, particularly the A2A receptor, play a significant role in reducing inflammation throughout the body.

Acute effects may include anxiety and panic, impaired attention and memory, an increased risk of psychotic symptoms, [b] the inability to think clearly, and an increased risk of accidents.[69][70][71] Cannabis impaired a person's driving ability, and THC was the illicit drug most frequently found in the blood of drivers who have been involved in vehicle crashes. Those with THC in their system were from three to seven times more likely to be the cause of the accident than those who had not used either cannabis or alcohol, although its role is not necessarily causal because THC stays in the bloodstream for days to weeks after intoxication.[72][73][c]

Recreational cannabis use centers around one chemical: the psychoactive cannabinoid tetrahydrocannabinol (THC). Consuming this chemical induces euphoric and stimulating sensations commonly referred to as a “high.” For most marijuana users, these sensations are pleasurable and enjoyable. For some, however, THC can induce feelings of anxiety and paranoia, especially in large doses.

A mixture of fiberglass, hemp fiber, kenaf, and flax has been used since 2002 to make composite panels for automobiles.[37] The choice of which bast fiber to use is primarily based on cost and availability. Various car makers are beginning to use hemp in their cars, including Audi, BMW, Ford, GM, Chrysler, Honda, Iveco, Lotus, Mercedes, Mitsubishi, Porsche, Saturn, Volkswagen[38] and Volvo. For example, the Lotus Eco Elise[39] and the Mercedes C-Class both contain hemp (up to 20 kg in each car in the case of the latter).[40]


The use of Cannabis for seed oil (Fig. 36) began at least 3 millennia ago. Hempseed oil is a drying oil, formerly used in paints and varnishes and in the manufacture of soap. Present cultivation of oilseed hemp is not competitive with linseed for production of oil for manufacturing, or to sunflower and canola for edible vegetable oil. However, as noted below, there are remarkable dietary advantages to hempseed oil, which accordingly has good potential for penetrating the salad oil market, and for use in a very wide variety of food products. There is also good potential for hemp oil in cosmetics and skin-care products.

Early this month, the FDA just approved a new drug for depression called esketamine. Esketamine, marketed under the brand name Spravato, is a ketamine-based drug designed for patients who aren’t responding to conventional antidepressant medications. It comes in a nasal spray form, and is touted to be the world’s first quick-relief depression medication in the market.

Both in Canada and the US, the most critical problem to be addressed for commercial exploitation of C. sativa is the possible unauthorized drug use of the plant. Indeed, the reason hemp cultivation was made illegal in North America was concern that the hemp crop was a drug menace. The drug potential is, for practical purposes, measured by the presence of THC. THC is the world’s most popular illicit chemical, and indeed the fourth most popular recreational drug, after caffeine, alcohol, and nicotine. “Industrial hemp” is a phrase that has become common to designate hemp used for commercial non-intoxicant purposes. Small and Cronquist (1976) split C. sativa into two subspecies: C. sativa subsp. sativa, with less than 0.3% (dry weight) of THC in the upper (reproductive) part of the plant, and C. sativa subsp. indica (Lam.) E. Small & Cronq. with more than 0.3% THC. This classification has since been adopted in the European Community, Canada, and parts of Australia as a dividing line between cultivars that can be legally cultivated under license and forms that are considered to have too high a drug potential. For a period, 0.3% was also the allowable THC content limit for cultivation of hemp in the Soviet Union. In the US, Drug Enforcement Agency guidelines issued Dec. 7, 1999 expressly allowed products with a THC content of less than 0.3% to enter the US without a license; but subsequently permissible levels have been a source of continuing contention. Marijuana in the illicit market typically has a THC content of 5% to 10% (levels as high as 25% have been reported), and as a point of interest, a current Canadian government experimental medicinal marijuana production contract calls for the production of 6% marijuana. As noted above, a level of about 1% THC is considered the threshold for marijuana to have intoxicating potential, so the 0.3% level is conservative, and some countries (e.g. parts of Australia, Switzerland) have permitted the cultivation of cultivars with higher levels. It should be appreciated that there is considerable variation in THC content in different parts of the plant. THC content increases in the following order: achenes (excluding bracts), roots, large stems, smaller stems, older and larger leaves, younger and smaller leaves, flowers, perigonal bracts covering both the female flowers and fruits. It is well known in the illicit trade how to screen off the more potent fractions of the plant in order to increase THC levels in resultant drug products. Nevertheless, a level of 0.3% THC in the flowering parts of the plant is reflective of material that is too low in intoxicant potential to actually be used practically for illicit production of marijuana or other types of cannabis drugs. Below, the problem of permissible levels of THC in food products made from hempseed is discussed.
In some areas where cannabis use had been historically tolerated, new restrictions were instituted, such as the closing of cannabis coffee shops near the borders of the Netherlands,[222] and closing of coffee shops near secondary schools in the Netherlands.[223] In Copenhagen, Denmark in 2014, mayor Frank Jensen discussed possibilities for the city to legalize cannabis production and commerce.[224]

The glutamatergic system is integral to development and maintenance of neuropathic pain, and is responsible for generating secondary and tertiary hyperalgesia in migraine and fibromyalgia via NMDA mechanisms (Nicolodi et al 1998). Thus, it is important to note that cannabinoids presynaptically inhibit glutamate release (Shen et al 1996), THC produces 30%–40% reduction in NMDA responses, and THC is a neuroprotective antioxidant (Hampson et al 1998). Additionally, cannabinoids reduce hyperalgesia via inhibition of calcitonin gene-related peptide (Richardson et al 1998a). As for Substance P mechanisms, cannabinoids block capsaicin-induced hyperalgesia (Li et al 1999), and THC will do so at sub-psychoactive doses in experimental animals (Ko and Woods 1999). Among the noteworthy interactions with opiates and the endorphin/enkephalin system, THC has been shown to stimulate beta-endorphin production (Manzanares et al 1998), may allow opiate sparing in clinical application (Cichewicz et al 1999), prevents development of tolerance to and withdrawal from opiates (Cichewicz and Welch 2003), and rekindles opiate analgesia after a prior dosage has worn off (Cichewicz and McCarthy 2003). These are all promising attributes for an adjunctive agent in treatment of clinical chronic pain states.
Of course, though, they offer less potent oils than that, with a product lineup that ranges from 300 mg CBD per bottle to 4,000 mg. Naturally the 4,000 mg option is the most expensive (this is the one that provides the “bomb” 60 mg dose), as it currently sells for $299. For long-term pain and anxiety relief, though, it may be well worth it if it is effective for you and helps replace your regular meds.

In the United States, cannabis is overall the number four value crop, and is number one or two in many states including California, New York and Florida, averaging $3,000 per pound ($6,600/kg).[256][257] Some believe it generates an estimated $36 billion market.[258] Some have argued that this estimate is methodologically flawed, and makes unrealistic assumptions about the level of marijuana consumption. Other estimates claiming to correct for this flaw claim that the market is between $2.1-$4.3 billion.[249] The United Nations Office on Drugs and Crime claims in its 2008 World Drug Report that typical U.S. retail prices are $10–15 per gram (approximately $280–420 per ounce). Street prices in North America are known to range from about $40–$400 per ounce ($1.4–$14/g), depending on quality.[259]
Conditions like rheumatoid arthritis and lupus impact the immune system which can lead to achy joints. These autoimmune disorders occur, in part, because the immune system is unable to recognize the body’s natural processes and begins to attack and destroy the wrong cells. Cannabinoids like CBD act as immune suppressors, reducing or eliminating this undesired immune response. Current testing and research shows positive results and as more studies are done, we will get a better picture of the ways in which CBD may be able to provide relief.
It is often claimed by growers and breeders of herbal cannabis that advances in breeding and cultivation techniques have increased the potency of cannabis since the late 1960s and early '70s when THC was first discovered and understood. However, potent seedless cannabis such as "Thai sticks" were already available at that time. Sinsemilla (Spanish for "without seed") is the dried, seedless inflorescences of female cannabis plants. Because THC production drops off once pollination occurs, the male plants (which produce little THC themselves) are eliminated before they shed pollen to prevent pollination. Advanced cultivation techniques such as hydroponics, cloning, high-intensity artificial lighting, and the sea of green method are frequently employed as a response (in part) to prohibition enforcement efforts that make outdoor cultivation more risky. It is often cited that the average levels of THC in cannabis sold in the United States rose dramatically between the 1970s and 2000, but such statements are likely skewed because undue weight is given to much more expensive and potent, but less prevalent samples.[253]
Hi Diane, how did you go on with the CBD oil please. If it worked how long before you saw any results. I'm scared of flaring everything. Nerve damage across buttocks from a surgeon who found the nerve stuck to the bulge during a laminectomy operation and prised it off. I haven't sat for 5 years and getting worse. A muscle in my buttock is now throbbing constantly and causing pain to the muscle above. I've only started taking it today but the muscle pain is still as painful. Does it take a while for it to work. Only started on low dose to see what happens. Thank you Lyn
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).
"Another chemical shared by both industrial hemp and marijuana is Cannabidiol (CBD).48 CBD is unique because it is not intoxicating and it also moderates the euphoric effect of THC.49 Marijuana, which has disproportionately higher levels of THC than industrial hemp, also contains lower levels of CBD.50 The higher THC and lower CBD concentration gives marijuana its psychoactive effect.51 Conversely, industrial hemp’s low THC levels and comparatively high CBD levels produce none of the intoxicating effects of marijuana.52"

CBD has some other very important jobs outside of the endocannabinoid system (ECS). For instance, CBD mildly activates one of the brain’s predominant serotonin receptors (5-HT1A), which may explain CBD’s effects on depression and anxiety. It also acts at the peroxisome proliferator activated receptors (PPARs), which halt the proliferation of cancer cells and convey neuro- and cardioprotection. By interacting with a particular PPAR (gamma), CBD could prove to be a promising new way to prevent alzheimer’s disease and other brain disorders.

"The import value of hemp-based products imported and sold in the United States is difficult to estimate accurately. For some traded products, available statistics have only limited breakouts or have been expanded only recently to capture hemp subcategories within the broader trade categories for oilseeds and fibers. Reporting errors are evident in some of the trade data, since reported export data for hemp from Canada do not consistently match reported U.S. import data for the same products (especially for hemp seeds).

Hempseed's amino acid profile is comparable to other sources of protein such as meat, milk, eggs and soy.[21] Protein digestibility-corrected amino acid scores (PDCAAS), which attempt to measure the degree to which a food for humans is a "complete protein", were 0.49–0.53 for whole hemp seed, 0.46–0.51 for hempseed meal, and 0.63–0.66 for hulled hempseed.[22]
Hemp plants are almost always cultivated outdoors, as opposed to marijuana plants, which are mostly planted in greenhouse or indoor settings. Because hemp is susceptible to the same predators diseases and insects that attack marijuana, the hemp industry employs a technique called crop rotation, in which alternating crops are planted in the same place, to avoid any buildup of these organisms and allow nutrients to return to the soil. The specific order of crop rotation and types of crops being rotated with hemp will depend on the location of the farm. Hemp is also used as a rotational crop at farms where it is not the primary agricultural product.
Would I say that CBD oil has fundamentally changed my life? No. But per the Charlotte's Web website, this is the typical first experience. "Anyone who has ever started a new vitamin or supplement routine knows the short answer to how long it takes to kick in is—'it depends,'" reads the article on what to expect from hemp oil. "For many newcomers, they're not sure what to imagine, or some anticipate a huge change right away. For most of us, though, dietary supplements take time."

A 100-gram portion of hulled hemp seeds supplies 586 calories. They contain 5% water, 5% carbohydrates, 49% total fat, and 31% protein. Hemp seeds are notable in providing 64% of the Daily Value (DV) of protein per 100-gram serving.[20] Hemp seeds are a rich source of dietary fiber (20% DV), B vitamins, and the dietary minerals manganese (362% DV), phosphorus (236% DV), magnesium (197% DV), zinc (104% DV), and iron (61% DV). About 73% of the energy in hempseed is in the form of fats and essential fatty acids,[20] mainly polyunsaturated fatty acids, linoleic, oleic, and alpha-linolenic acids.[21]
