Hemp can be used as a "mop crop" to clear impurities out of wastewater, such as sewage effluent, excessive phosphorus from chicken litter, or other unwanted substances or chemicals. Additionally, hemp is being used to clean contaminants at the Chernobyl nuclear disaster site, by way of a process which is known as phytoremediation—the process of clearing radioisotopes and a variety of other toxins from the soil, water, and air.
Moreover, scientists at the Cajal Institute showed promising results in regards to CBD and Multiple Sclerosis. They used animal models and cell cultures to find that CBD reversed inflammatory responses; within only ten days, mice that were used in the study had superior motor skills and showed progression in their condition. To date, there have been well over 20,000 published scientific articles on cannabinoids and their related effects on all sorts of medical ailments.
In the United Kingdom, cultivation licences are issued by the Home Office under the Misuse of Drugs Act 1971. When grown for nondrug purposes, hemp is referred to as industrial hemp, and a common product is fibre for use in a wide variety of products, as well as the seed for nutritional aspects and for the oil. Feral hemp or ditch weed is usually a naturalized fibre or oilseed strain of Cannabis that has escaped from cultivation and is self-seeding.
Fig. 5. Typical architecture of categories of cultivated Cannabis sativa. Top left: narcotic plants are generally low, highly branched, and grown well-spaced. Top right: plants grown for oilseed were traditionally well-spaced, and the plants developed medium height and strong branching. Bottom left: fiber cultivars are grown at high density, and are unbranched and very tall. Bottom center: “dual purpose” plants are grown at moderate density, tend to be slightly branched and of medium to tall height. Bottom right: some recent oilseed cultivars are grown at moderate density and are short and relatively unbranched. Degree of branching and height are determined both by the density of the plants and their genetic background.
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. 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 0.3% on a dry-weight basis. 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 dry-weight THC concentration does not exceed 0.3%.
The nutrition and supplement industry—which includes CBD products—is almost wholly unregulated. “The concentrations in products are only approximate, and I don’t know how well they’re tracked,” Szaflarski says. Even if you could absolutely trust a product’s label—and many CBD manufacturers, aware of the current scrutiny on their industry, go to great lengths to assure consumers of the quality of their products—there aren’t a lot of concrete facts when it comes to the type or amount of CBD a person should take for a specific ailment or aim.
"The presence of THC in these products has been a source of concern for the military and other workplace drug-testing programs. Ingestion of hemp products has been historically used as a defense in military and civilian trials for many years and continues today despite decreased concentrations of THC in hemp products (10-12). The Division of Forensic Toxicology, Armed Forces Institute of Pathology is often asked to analyze hemp products to determine their THC content in addition to rendering an opinion as to whether or not this THC concentration could be a reasonable cause for a positive THC metabolite urine analysis result."
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.
Infusions: Research and opportunity have driven chefs and chemists to infuse CBD into all sorts of readily usable products, such as edibles to elixirs, sublingual sprays, capsules and even topicals. Much like concentrates, each infusion sports specific combinations or isolations of CBD, THC, and other cannabinoids, allowing users to pick and choose products that suit their exact needs. CBD topicals, for example, are incredibly effective when applied to surface-level problems like bruises, joint aches, and headaches, and have been scientifically proven to successfully combat skin-based issues including pruritus with far broader implications.
I am a former family doctor and naturopathic physician as well as a medical editor and author, working mostly in academic research. In my practice I have always focused on natural medicine and helped my patients of all ages who haven’t responded to traditional treatments. I also have written a significant number of articles in botanical medicine, addiction, drugs. As of now I'm focused on cannabis researches, especially on cannabidiol, its health benefits and how it can improve life of people with severe diseases. You can read my articles here on CBDreamers
Outside of the aforementioned studies, CBD’s progress toward its place in society today suffered from intermittent spurts and starts until 1996 when California became the first US state to legalize medical cannabis. This groundbreaking moment paved the way for public support and lucrative research opportunities. Other states including Oregon, Alaska, Washington, Maine, Hawaii, Nevada, and Colorado would follow suit before the close of 2000.
Scott Shannon, M.D., assistant clinical professor at the University of Colorado, recently sifted through patient charts from his four-doctor practice to document CBD’s effects on anxiety. His study, as yet unpublished, found “a fairly rapid decrease in anxiety scores that appears to persist for months,” he says. But he says he can’t discount a placebo effect, especially since “there’s a lot of hype right now.”
And the final nail in industrial hemp’s proverbial coffin: Federal law in the United States prohibits the use of hemp leaves and flowers to make drug products. That said, isolating CBD nullifies these distinctions, rendering its source irrelevant as CBD isolate contains nothing but CBD. In this case, the differences between industrial hemp and whole-plant marijuana are far less significant.
Cannabis Indica – The annual plant of the Cannabaceae family is considered a species of the genus Cannabis, but separate from Cannabis sativa, and originating in the Hindu Kush Mountains and suited for cultivation in temperate climates. Used to induce sleep, the plant is described as relatively short and conical with dense branches and short, broad leaves, while Cannabis sativa is tall with fewer branches and long, narrow leaves.
PTSD. My husband suffers chronic PTSD from active military service. We live not far from a large Army base and though my husband served with another counties military we hear stories constantly of family breakdowns over PTSD. It’s not a easy path but I’m hoping one day to find something to stop the endless trips to the psych ward. It’s just not right that those who serve come home to no government help.
38 states and Puerto Rico considered legislation related to industrial hemp in 2017. These bills ranged from clarifying existing laws to establishing new licensing requirements and programs. At least 15 states enacted legislation in 2017 — Arkansas, Colorado, Florida, Hawaii, North Dakota, Nevada, New York, Oregon, South Carolina, Tennessee, Virginia, Washington, West Virginia, Wisconsin and Wyoming. At least four states — Florida, Nevada, New Mexico and Wisconsin — authorized new research or pilot programs.
^ A 2016 review also found a statistically significant increase in crash risk associated with marijuana use, but noted that this risk was "of low to medium magnitude." The increase in risk of motor vehicle crash for cannabis use is between 2 and 3 times relative to baseline, whereas that for comparable doses of alcohol is between 6 and 15 times.
Cannabis use started to become popular in the United States in the 1970s. Support for legalization has increased in the United States and several U.S. states have legalized recreational or medical use. A 2018 Social Science Research study found that the main determinants of such changes in attitudes toward marijuana regulation since the 1990s were changes in media framing of marijuana, a decline in perception of the riskiness of marijuana, a decline in overall punitiveness, and a decrease in religious affiliation. 
Reflecting the next morning, I was most surprised by the fact that I never felt "high" in any way—there was never a moment of It's kicking in; I can feel it now like with pain medications or even anti-anxiety drugs. Considering it takes time, consistency, and the right dosage to experience the full effect, I continued taking the oil once a day for the next six days. Here's what went down.

Given CBD’s reputation as a popular, artisanal remedy, one would think that Epidiolex would command a lot of “off label” attention. After all, physicians often prescribe pharmaceuticals off label to treat conditions that were not the actual focus of clinical trials. But the costly price tag for Epidiolex (more than $30,000 annually) precludes off label prescribing as well as affordable access for tens of millions of Americans without health insurance.
"Approximately 30 countries in Europe, Asia, and North and South America currently permit farmers to grow hemp. Some of these countries never outlawed production, while some countries banned production for certain periods in the past. China is among the largest producing and exporting countries of hemp textiles and related products, as well as a major supplier of these products to the United States. The European Union (EU) has an active hemp market, with production in most member nations. Production is centered in France, the United Kingdom, Romania, and Hungary.30
I wouldn’t recommend the Lord Jones cream for deep tissue pain so much as surface-level aches: When I’m feeling pain on the pads of my feet, I rub a pump or two of this stuff on the area, which feels almost like applying lidocaine, except the lotion smells danker. My mother, who’s morally opposed to anything remotely weed-related, even took to it after I slipped her some for her painful, cracked winter hands. When I explained later what CBD was, she said, “Oh,” and after a beat, “I guess I did wonder why I stopped feeling anything.”
The results of the three large European cohort studies have been confirmed in two smaller New Zealand birth cohorts. Arsenault and colleagues (2002) reported a prospective study of the relationship between adolescent cannabis use and psychosis in a New Zealand birth cohort (n = 759). They found a relationship between cannabis use by age 15 and an increased risk of psychotic symptoms by age 26. The relationship did not change when they controlled for other drug use, but it was no longer statistically significant after adjusting for psychotic symptoms at age 11. The latter probably reflected the small number of psychotic disorders observed in the sample. Fergusson et al. (2003) found a relationship between cannabis dependence at age 18 and later symptoms that included those in the psychotic spectrum reported at age 21 in the Christchurch birth cohort. Fergusson and colleagues adjusted for a large number of potential confounding variables, including self-reported psychotic symptoms at the previous assessment, other drug use and other psychiatric disorders, but whether the association represents a link between cannabis use and psychotic symptoms specifically, or more general psychiatric morbidity, remains unclear.
From 1982 to 2002 the EU provided the equivalent of about 50 million dollars to develop new flax and hemp harvesting and fiber processing technologies (Karus et al. 2000). Because of the similarities of flax and hemp, the technologies developed for one usually are adaptable to the other. In addition, various European nations and private firms contributed to the development of hemp technologies. Accordingly, Europe is far more advanced in hemp development with respect to all fiber-based applications than other parts of the world. The EU currently dedicates about 30,000 ha to hemp production. France is the leading country in hemp cultivation in the EU, and 95% of the non-seed production is used for “specialty pulp” as described below. Harvesting and processing machinery for fiber hemp is highly advanced in Europe, and some has been imported into Canada. However, there is insufficient fiber processing capacity to handle hemp produced in Canada.
CBD Isolates/Concentrates: Anyone familiar with smoking hash or other cannabis concentrates like wax and BHO will be no stranger to this delivery method. Simply sprinkle some into a vaporizer or water pipe, ignite, inhale, and enjoy! We find that this option is useful for individuals looking to elevate their regular consumption of CBD-rich cannabis flowers or other smokable herbs.
In the EU and Canada, hemp has often been grown as a dual-purpose crop, i.e. for both fiber and oilseed. In France, dual purpose hemp is typically harvested twice—initially the upper seed-bearing part of the stems is cut and threshed with a combine, and subsequently the remaining stems are harvested. Growing hemp to the stage that mature seeds are present compromises the quality of the fiber, because of lignification. As well, the hurds become more difficult to separate. The lower quality fiber, however, is quite utilizable for pulp and non-woven usages.
Hemp is thus profitable and sustainable, two words which have eluded many U.S. farmers as of late. Hemp cultivation could provide much-needed relief as farmers struggle to find markets for millions of bushels of crops during the trade wars. Now, instead of importing an estimated $100 million of hemp products every year, that money will go to American farmers and entrepreneurs.
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. 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, mainly polyunsaturated fatty acids, linoleic, oleic, and alpha-linolenic acids.
