Then came World War II. The Japanese attack on Pearl Harbor shut off foreign supplies of "manila hemp" fiber from the Philippines. The USDA produced a film called "Hemp For Victory" to encourage U.S. farmers to grow hemp for the war effort. The U.S. government formed the War Hemp Industries Department and subsidized hemp cultivation. During the war, U.S. farmers grew about a million acres of hemp across the Midwest as part of that program.
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.
Textile expert Elizabeth Wayland Barber summarizes the historical evidence that Cannabis sativa, "grew and was known in the Neolithic period all across the northern latitudes, from Europe (Germany, Switzerland, Austria, Romania, Ukraine) to East Asia (Tibet and China)," but, "textile use of Cannabis sativa does not surface for certain in the West until relatively late, namely the Iron Age."[107] "I strongly suspect, however, that what catapulted hemp to sudden fame and fortune as a cultigen and caused it to spread rapidly westwards in the first millennium B.C. was the spread of the habit of pot-smoking from somewhere in south-central Asia, where the drug-bearing variety of the plant originally occurred. The linguistic evidence strongly supports this theory, both as to time and direction of spread and as to cause."[108]
An absence of such fiber-strain traits as tallness, limited branching, long internodes, and very hollow stems, is characteristic of narcotic strains. Drug forms have historically been grown in areas south of the north-temperate zone, often close to the equator, and are photoperiodically adapted to a long season. When grown in north-temperate climates maturation is much-delayed until late fall, or the plants succumb to cold weather before they are able to produce seeds. Unlike fiber strains that have been selected to grow well at extremely high densities, drug strains tend to be less persistent when grown in high concentration (de Meijer 1994). Drug strains can be very similar in appearance to fiber strains. However, a characteristic type of narcotic plant was selected in southern Asia, particularly in India and neighboring countries. This is dioecious, short (about a meter in height), highly branched, with large leaves (i.e. wide leaflets), and it is slow to mature. The appearance is rather like a short, conical Christmas tree.
Traditionally, hemp stalks would be water-retted first before the fibers were beaten off the inner hurd by hand, a process known as scutching. As mechanical technology evolved, separating the fiber from the core was accomplished by crushing rollers and brush rollers that would produce a nearly clean fiber. After the Marijuana Tax Act was implemented in 1938, the technology for separating the fibers from the core remained "frozen in time".
THC, an intoxicating and illegal substance, is responsible for causing marijuana users to get “high.” Unlike THC, CBD is non-psychoactive because it does not act on the same pathways as THC. Thus, it is impossible to get “high” by smoking or ingesting CBD or CBD oil extracted from industrial hemp plants, as they only have minuscule traces of THC (<0.3%).

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]
Liquid CBD Oil/Tinctures/Extracts: Drops or tinctures should have a “suggested serving size” and the total milligrams of CBD listed on their packaging. From there, you can determine the amount of CBD you would like to ingest. Simply place the correct quantity of drops under your tongue using the dropper and hold the CBD oil in place for a minimum of 60 seconds. The 60 second hold allows for absorption via the blood vessels underneath your tongue – efficiently bypassing first-pass metabolism. Once 60 seconds has passed, swallow the CBD oil.
Cannabis is an annual, dioecious, flowering herb. The leaves are palmately compound or digitate, with serrate leaflets.[10] The first pair of leaves usually have a single leaflet, the number gradually increasing up to a maximum of about thirteen leaflets per leaf (usually seven or nine), depending on variety and growing conditions. At the top of a flowering plant, this number again diminishes to a single leaflet per leaf. The lower leaf pairs usually occur in an opposite leaf arrangement and the upper leaf pairs in an alternate arrangement on the main stem of a mature plant.
The main difference between the two is in its chemical composition, specifically in tetrahydrocannabinol (THC). THC is the chemical responsible marijuana’s psychological effects.An average batch of marijuana contains anywhere from 5-20% THC content. Some premium marijuana can have up to 25-30% THC. Hemp, on the other hand, has a max THC level of 0.3%, essentially making it impossible to feel any psychoactive effect or get a “high”. This threshold is heavily regulated in other countries that have legalized hemp.Hemp also has high cannabidiol (CBD) content that acts as THC’s antagonist, essentially making the minimal amount of THC useless.

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.

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.

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.
A 2012 review found that the THC content in marijuana had increased worldwide from 1970 to 2009.[150] It is unclear, however, whether the increase in THC content has caused people to consume more THC or if users adjust based on the potency of the cannabis. It is likely that the higher THC content allows people to ingest less tar. At the same time, CBD levels in seized samples have lowered, in part because of the desire to produce higher THC levels and because more illegal growers cultivate indoors using artificial lights. This helps avoid detection but reduces the CBD production of the plant.[151]
I have/had ovarian/primary peritoneal cancer. I used thc/cbd oil pills I self made from the start. I am supposedly their “poster child”. I went thru with chemo and surgery. Oh that horror! But when I tried to tell two seperate doctors, the surgeon was all about it, and my oncologist threw a fit and said it was an anecdote. There are more than 100 studies at the NIH govt website.
Down the line, Johnson also plans to create an onsite grow-space in the large two-story building where he's set up shop. In addition to getting deep satisfaction from the relief that customers say his CBD products provide, Johnson remains enthralled with "the fun side" of hemp production: namely, planting a seed and letting it grow. "It's just like in life," he added. "I can't say enough about the process, about the feeling of actually producing something."
Hemp is the fiber and seed part of the Cannabis Sativa L. plant, opposed to the flower part of the plant which is “legally considered” marijuana.  The fiber and seeds are incredible valuable and is why hemp is often called a “cash crop”.  Hemp is a very hearty plant and grows very quickly in very diverse soil conditions.  Cultivation of hemp for industrial purposes has been done by many civilizations for over 12,000 years.   Industrial hemp was the desired fiber used to manufacture rope, canvas, paper, and clothing until alternative textiles and synthetics for these purposes were discovered.  Although China has been the largest hemp producer over the years, other countries such as Australia and Canada are catching up.  It has been illegal for anyone to grow hemp in the United States as hemp is illegal under the marijuana prohibition act but Colorado has changed the laws and paved the way for industrial hemp production again in the United States(see hemp history). Now hemp oils, hemp plastics, hemp building materials and many hemp fiber products can be seen and purchased on the market. Hemp is truly an amazing plant with the potential to help “green up” many industries.
What makes CBD so appealing is that it’s non-intoxicating, so it won’t get you high, though it “is technically psychoactive, because it can influence things like anxiety,” Jikomes said. Although much of the marketing blitz around CBD centers on the fact that you can take it without getting stoned, there isn’t much research looking at the effects of CBD when used in isolation, with a couple of exceptions. One is the use of CBD to treat seizures: CBD is the active ingredient in the only cannabis product that the Food and Drug Administration has signed off on — a drug called Epidiolex, which is approved for treating two rare forms of epilepsy. Animal models and a few human studies suggest that CBD can help with anxiety, but those are the only conditions with much research on CBD in isolation.
The CBD oil needs to be taken twice a day everyday. The dosage depends on symptoms and it takes 30 days to awken your natural cannabis system after you begin taking the oil. I personally use Hemp works CBD oil in the 750 strength and only need 5 drops sublingual 2 times daily and results are many. Problem with oil and alz.patients is getting them to hold oil under tongue for 60 seconds. We have just began to get my dad on it. He too is in a nursing home in the state of florida and they cannot deny him any medication my mom has requested that he receive. If she is not their they are supposed to administer and she will call them to make sure he gets it. He is not 30 days into dosing yet so I don't have any results to speak of. I do know that since he has started he has had no more bladder infection and has not fallen in 3 weeks. That's a record for him so we will continue to monitor. Best of luck to you and a lot is going to depend on the state your mom is in and what the state laws are concerning her rights or the rights of whom has her medical power of attorney
If you haven’t been bombarded with CBD marketing or raves about it from friends, get ready. This extract—which comes from either marijuana or its industrial cousin, hemp—is popping up everywhere. There are CBD capsules, tinctures, and liquids for vaping plus CBD-infused lotions, beauty products, snacks, coffee, and even vaginal suppositories. Already some 1,000 brands of CBD products are available in stores—and online in states that don’t have lenient cannabis laws. This is a tiny fraction of what’s to come: The CBD market is poised to exceed $1 billion by 2020, per the Chicago-based research firm Brightfield Group.
Fatty Acids. The quality of an oil or fat is most importantly determined by its fatty acid composition. Hemp is of high nutritional quality because it contains high amounts of unsaturated fatty acids, mostly oleic acid (C18:1, 10%–16%), linoleic acid (C18:2, 50%–60%), alpha-linolenic acid (C18:3, 20%–25%), and gamma-linolenic acid (C18:3, 2%–5%) (Fig. 37). Linoleic acid and alpha-linolenic acid are the only two fatty acids that must be ingested and are considered essential to human health (Callaway 1998). In contrast to shorter-chain and more saturated fatty acids, these essential fatty acids do not serve as energy sources, but as raw materials for cell structure and as precursors for biosynthesis for many of the body’s regulatory biochemicals. The essential fatty acids are available in other oils, particularly fish and flaxseed, but these tend to have unpleasant flavors compared to the mellow, slightly nutty flavor of hempseed oil. While the value of unsaturated fats is generally appreciated, it is much less well known that the North American diet is serious nutritionally unbalanced by an excess of linoleic over alpha-linonenic acid. In hempseed, linoleic and alpha-linolenic occur in a ratio of about 3:1, considered optimal in healthy human adipose tissue, and apparently unique among common plant oils (Deferne and Pate 1996). Gamma-linolenic acid or GLA is another significant component of hemp oil (1%–6%, depending on cultivar). GLA is a widely consumed supplement known to affect vital metabolic roles in humans, ranging from control of inflammation and vascular tone to initiation of contractions during childbirth. GLA has been found to alleviate psoriasis, atopic eczema, and mastalgia, and may also benefit cardiovascular, psychiatric, and immunological disorders. Ageing and pathology (diabetes, hypertension, etc.) may impair GLA metabolism, making supplementation desirable. As much as 15% of the human population may benefit from addition of GLA to their diet. At present, GLA is available in health food shops and pharmacies primarily as soft gelatin capsules of borage or evening primrose oil, but hemp is almost certainly a much more economic source. Although the content of GLA in the seeds is lower, hemp is far easier to cultivate and higher-yielding. It is important to note that hemp is the only current natural food source of GLA, i.e. not requiring the consumption of extracted dietary supplements. There are other fatty acids in small concentrations in hemp seed that have some dietary significance, including stearidonic acid (Callaway et al. 1996) and eicosenoic acid (Mölleken and Theimer 1997). Because of the extremely desirable fatty acid constitution of hemp oil, it is now being marketed as a dietary supplement in capsule form (Fig. 38).

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.
The genus Cannabis was first classified using the "modern" system of taxonomic nomenclature by Carl Linnaeus in 1753, who devised the system still in use for the naming of species.[59] He considered the genus to be monotypic, having just a single species that he named Cannabis sativa L. (L. stands for Linnaeus, and indicates the authority who first named the species). Linnaeus was familiar with European hemp, which was widely cultivated at the time. In 1785, noted evolutionary biologist Jean-Baptiste de Lamarck published a description of a second species of Cannabis, which he named Cannabis indica Lam.[60] Lamarck based his description of the newly named species on plant specimens collected in India. He described C. indica as having poorer fiber quality than C. sativa, but greater utility as an inebriant. Additional Cannabis species were proposed in the 19th century, including strains from China and Vietnam (Indo-China) assigned the names Cannabis chinensis Delile, and Cannabis gigantea Delile ex Vilmorin.[61] However, many taxonomists found these putative species difficult to distinguish. In the early 20th century, the single-species concept was still widely accepted, except in the Soviet Union where Cannabis continued to be the subject of active taxonomic study. The name Cannabis indica was listed in various Pharmacopoeias, and was widely used to designate Cannabis suitable for the manufacture of medicinal preparations.[62]

Cannabis, (genus Cannabis), plant belonging to the family Cannabaceae of the nettle order (Urticales). By some classifications, the genus Cannabis comprises a single species, hemp (Cannabis sativa), a stout, aromatic, erect annual herb that originated in Central Asia and is now cultivated worldwide, including in Europe, southern Asia, the Middle East, India, Africa, and the Americas. A tall canelike variety is raised for the production of hemp fibre, while the female plant of a short branchier variety is prized as the more abundant source of the psychoactive substance tetrahydrocannabinol (THC), the active ingredient of marijuana.
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.
In recent years, hemp has been growing in popularity as a material used in shoes. Today you can find boots, athletic shoes, sandals, and dress shoes that are made with 100% hemp fiber, or textiles that blend hemp fibers with materials such as cotton, jute, virgin polyester, and recycled polyester. The strength of hemp fibers makes it an ideal material for shoes because it's durable. In addition, it's breathable and naturally antimicrobial, so it doesn't hold on to odors.[41] Because hemp can be grown sustainably, shoes, clothing, and accessories made with hemp are representative of the sustainable fashion movement.
