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.

Some users may experience an episode of acute psychosis, which usually abates after six hours, but in rare instances, heavy users may find the symptoms continuing for many days.[52] A reduced quality of life is associated with heavy cannabis use, although the relationship is inconsistent and weaker than for tobacco and other substances.[53] It is unclear, however, if the relationship is cause and effect.[53]
In the early 1990s, industrial hemp agriculture in North America began with the Hemp Awareness Committee at the University of Manitoba. The Committee worked with the provincial government to get research and development assistance, and was able to obtain test plot permits from the Canadian government. Their efforts led to the legalization of industrial hemp (hemp with only minute amounts of tetrahydrocannabinol) in Canada and the first harvest in 1998.[77][78]
The most pressing need of the hemp industry in North America is for the breeding of more productive oilseed cultivars. At present, mainly European cultivars are available, of which very few are suitable for specialized oilseed production. More importantly, hempseed oil is not competitive, except in the novelty niche market, with the popular food oils. As argued above, to be competitive, hemp should produce approximately 2 t/ha; at present 1 t/ha is considered average to good production. Doubling the productive capacity of a conventional crop would normally be considered impossible, but it needs to be understood just how little hemp has been developed as an oilseed. There may not even be extant land races of the kind of hemp oilseed strains that were once grown in Russia, so that except for a very few very recent oilseed cultivars, there has been virtually no breeding of oilseed hemp. Contrarily, hemp has been selected for fiber to the point that some breeders consider its productivity in this respect has already been maximized. Fiber strains have been selected for low seed production, so that most hemp germplasm has certainly not been selected for oilseed characteristics. By contrast, drug varieties have been selected for very high yield of flowers, and accordingly produce very high yield of seeds. Drug varieties have been observed to produce more than a kilogram of seed per plant, so that a target yield of several tonnes per hectare is conceivable (Watson and Clarke 1997). Of course, the high THC in drug cultivars makes these a difficult source of germplasm. However, wild plants of C. sativa have naturally undergone selection for high seed productivity, and are a particularly important potential source of breeding germplasm.
Hemp is a multi-purpose agricultural crop delivering seeds, fibers and bio-active chemicals for a number of uses and markets. Industrial hemp is defined in federal and Montana statute as Cannabis sativa L. that contains no more than 0.3% delta-9 tetrahydrocannabinol (THC). Industrial hemp is authorized as an alternative agricultural crop by the Montana Legislature, Section 80-18-101 through 80-18-111 of Montana Code Annotated.
The term hemp is used to name the durable soft fiber from the Cannabis plant stem (stalk). Cannabis sativa cultivars are used for fibers due to their long stems; Sativa varieties may grow more than six metres tall. However, hemp can refer to any industrial or foodstuff product that is not intended for use as a drug. Many countries regulate limits for psychoactive compound (THC) concentrations in products labeled as hemp.
At least 38 states considered legislation related to industrial hemp in 2018. These bills ranged from clarifying existing laws to establishing new licensing requirements and programs. At least 5 states – Alaska, Arizona, Kansas, Missouri and Oklahoma – enacted legislation in 2018 establishing hemp research and industrial hemp pilot programs. Georgia adopted a resolution to create the House Study Committee on Industrial Hemp Production. States, already allowing for industrial hemp programs, continued to consider policies related to licensure, funding, seed certification, and other issues. For example, Tennessee amended its Commercial Feed Law to include hemp. 
While cultivating marijuana’s non-intoxicating cousin is currently illegal in the U.S. outside of exceptions for state-approved hemp research programs authorized under the 2014 Farm Bill, there’s a strong possibility that industrial hemp will be broadly legalized—possibly by the end of the year—once the House and Senate reconcile their versions of a new Farm Bill and put it on the president’s desk.
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.
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.[86]
Air-dried stem yields in Ontario have from 1998 and onward ranged from 2.6-14.0 tonnes of dry, retted stalks per hectare (1-5.5 t/ac) at 12% moisture. Yields in Kent County, have averaged 8.75 t/ha (3.5 t/ac). Northern Ontario crops averaged 6.1 t/ha (2.5 t/ac) in 1998. Statistic for the European Union for 2008 to 2010 say that the average yield of hemp straw has varied between 6.3 and 7.3 ton per ha.[67][68] Only a part of that is bast fiber. Around one tonne of bast fiber and 2-3 tonnes of core material can be decorticated from 3-4 tonnes of good-quality, dry-retted straw. For an annual yield of this level is it in Ontario recommended to add nitrogen (N):70–110 kg/ha, phosphate (P2O5): up to 80 kg/ha and potash (K2O): 40–90 kg/ha.[69] The average yield of dry hemp stalks in Europe was 6 ton/ha (2.4 ton/ac) in 2001 and 2002.[14]

Despite advanced analytical techniques, much of the cannabis used recreationally is inaccurately classified. One laboratory at the University of British Columbia found that Jamaican Lamb’s Bread, claimed to be 100% sativa, was in fact almost 100% indica (the opposite strain).[82] Legalization of cannabis in Canada (as of October 17, 2018) may help spur private-sector research, especially in terms of diversification of strains. It should also improve classification accuracy for cannabis used recreationally. Legalization coupled with Canadian government (Health Canada) oversight of production and labelling will likely result in more -- and more accurate -- testing to determine exact strains and content. Furthermore, the rise of craft cannabis growers in Canada should ensure quality, experimentation/research, and diversification of strains among private-sector producers.[83]

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]
Canadian experience with growing hemp commercially for the last 4 years has convinced many growers that it is better to use a single-purpose cultivar, seed or fiber, than a dual-purpose cultivar. The recent focus of Canadian hemp breeders has been to develop cultivars with high seed yields, low stature (to avoid channeling the plants’ energy into stalk, as is the case in fiber cultivars), early maturation (for the short growing seasons of Canada), and desirable fatty acid spectrum (especially gamma-linolenic acid).
“Hemp is of high nutritional quality because it contains high amounts of unsaturated fatty acids… Linoleic acid and alpha-linolenic acid are the only two fatty acids that must be ingested and are considered essential to human health … 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…”  
As I research more I am disgusted with how we have all been deceived. I feel confident now with being able to research things on our own, at any moment in time, we can begin to take back our world. In the early 30’s one of the great media conspiracies unfolded. Publisher William Hearst, Dupont, the petroleum interests, the cotton lobby, the bankers and some ignorant politicians lead a crusade to ban hemp to line their pockets. Hemp can revolutionize our society. Please research and pass on!
Please note that we are not qualified to give medical advice. ur CBD oil is made from high quality hemp at 5% and has a base of extra virgin olive oil. CBD oil has less than 0.2% THC in it, that's one of the reasons why it's legal in the first place. The effects will vary from person to person, but we are receiving very good feedback from customers who have bought our oil. We always recommend to start with a small dosage and increase if you do not feel any effect.
Will hemp commercial cultivation resume in the US in the foreseeable future? This is difficult to judge, but the following considerations suggest this might occur: (1) increasing awareness of the differences between industrial hemp and marijuana; (2) growing appreciation of the environmental benefits of hemp cultivation; (3) continuing demonstration of successful hemp cultivation and development in most of the remaining western world; all the G8 countries, except the US, produce and export industrial hemp; and (4) increasing pressure on state and federal governments to permit hemp cultivation by farmers, particularly wheat, corn, and tobacco farmers in desperate need of substitute crops, but also for rotation crops to break pest and disease cycles.
And without high-quality trials, experts don’t know how much is best for a given purpose. The staff at Roth’s dispensary told her, “Try some once or twice a day and see what happens.” (Half a dropper’s worth was a good amount for her.) One thing scientists feel confident about is that CBD is not dangerous. It won’t damage vital organs even at doses as high as 5,000 mg a day, Marcu says, and nobody has died from simply overdosing on a cannabis product.
There is great variation in Cannabis sativa, because of disruptive domestication for fiber, oilseed, and narcotic resin, and there are features that tend to distinguish these three cultigens (cultivated phases) from each other. Moreover, density of cultivation is used to accentuate certain architectural features. Figure 5 illustrates the divergent appearances of the basic agronomic categories of Cannabis in typical field configurations.
Nevertheless, every bit of this ancient plant is useful and valuable, and not just for rope, but for textiles, auto parts, cosmetics, dynamite, supplements, food, and medicine. In ancient China, hemp seed was regarded as food for the lower classes, and in Europe, a peanut butter-like spread was made from the seeds, in both cases with the hulls intact.
My husband has RSD and we are considering CBD oil -= I would ask at Hempmed because the spray won't have enough in it. Our dgt';s friend has ovarian cancer and it is shrinking her tumors but the spray would never have been enough. I would get CBD oil and check with Hempmeds to see what they suggest. It isn't cheap but it does work. LOW dose Naltrexone about 4.5 mg is very helpful for RSD and is usually used for getting people off of drugs but is working on turning off the glial cells that surround the nerve that is causing the nerve to scream in pain. We are also using PeaPure that is out of the Netherlands and we are seeing a response, even though small. His other leg touched the painful leg without causing more severe pain. That is progress. We also are using Poison Ivy Cream through Meadowlake Farms that has helped the burning surface pain. Change your diet and get rid of Gluten and Sugar, anything that causes inflammation. This is to allow your own body to work. Absolutely do not use any pain killers as it will turn up your pain. all the Hydrocodone, etc causes neural inflammation and so it will keep cascading higher your pain. Hope this is helpful. Mary

Jews living in Palestine in the 2nd century were familiar with the cultivation of hemp, as witnessed by a reference to it in the Mishna (Kil'ayim 2:5) as a variety of plant, along with Arum, that sometimes takes as many as three years to grow from a seedling. In late medieval Germany and Italy, hemp was employed in cooked dishes, as filling in pies and tortes, or boiled in a soup.[109] Hemp in later Europe was mainly cultivated for its fibers, and was used for ropes on many ships, including those of Christopher Columbus. The use of hemp as a cloth was centered largely in the countryside, with higher quality textiles being available in the towns.


In addition to acting on the brain, CBD influences many body processes. That’s due to the endocannabinoid system (ECS), which was discovered in the 1990s, after scientists started investigating why pot produces a high. Although much less well-known than the cardiovascular, reproductive, and respiratory systems, the ECS is critical. “The ECS helps us eat, sleep, relax, forget what we don’t need to remember, and protect our bodies from harm,” Marcu says. There are more ECS receptors in the brain than there are for opioids or serotonin, plus others in the intestines, liver, pancreas, ovaries, bone cells, and elsewhere.
Hemp, Canabis sativa is a plant originally from central Asia. It was cultivated with, and sometimes in place of flax because the stem fibers are similar. By the seventeenth century, Russia, Latvia, and other countries around the Baltic Sea were the major producers of hemp. It was from these areas Britain obtained its supply. However, during periods of military hostilities, the English had trouble acquiring enough hemp.
exhaustion and pain that kept her on the couch much of the day. The 58-year-old Seattle speech coach didn’t want to take opioid pain-killers, but Tylenol wasn’t helping enough. Roth was intrigued when women in her online chat group enthused about a cannabis-derived oil called cannabidiol (CBD) that they said relieved pain without making them high. So Roth, who hadn’t smoked weed since college but lived in a state where cannabis was legal, walked into a dispensary and bought a CBD tincture. “Within a few hours of placing the drops in my mouth, the malaise and achiness that had plagued me for weeks lifted and became much more manageable,” she says. She took the drops several times a day and in a few weeks was back to her regular life.

Cannabis has psychoactive and physiological effects when consumed.[44] The immediate desired effects from consuming cannabis include relaxation and euphoria (the "high" or "stoned" feeling), a general alteration of conscious perception, increased awareness of sensation, increased libido[45] and distortions in the perception of time and space. At higher doses, effects can include altered body image, auditory and/or visual illusions, pseudohallucinations and ataxia from selective impairment of polysynaptic reflexes. In some cases, cannabis can lead to dissociative states such as depersonalization[46][47] and derealization.[48]
A mixture of fiberglass, hemp fiber, kenaf, and flax has been used since 2002 to make composite panels for automobiles.[34] 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[35] and Volvo. For example, the Lotus Eco Elise[36] and the Mercedes C-Class both contain hemp (up to 20 kg in each car in the case of the latter).[37]
