Hemp does best on a loose, well-aerated loam soil with high fertility and abundant organic matter. Well-drained clay soils can be used, but poorly-drained clay soils are very inappropriate because of their susceptibility to compaction, which is not tolerated. Young plants are sensitive to wet or flooded soils, so that hemp must have porous, friable, well-drained soils. Sandy soils will grow good hemp, provided that adequate irrigation and fertilization are provided, but doing so generally makes production uneconomical. Seedbed preparation requires considerable effort. Fall plowing is recommended, followed by careful preparation of a seedbed in the spring. The seedbed should be fine, level, and firm. Seed is best planted at 2–3 cm (twice as deep will be tolerated). Although the seedlings will germinate and survive at temperatures just above freezing, soil temperatures of 8°–10°C are preferable. Generally hemp should be planted after danger of hard freezes, and slightly before the planting date of maize. Good soil moisture is necessary for seed germination, and plenty of rainfall is needed for good growth, especially during the first 6 weeks. Seeding rate is specific to each variety, and this information should be sought from the supplier. Fiber strains are typically sown at a minimum rate of 250 seeds per m2 (approximately 45 kg/ha), and up to three times this density is sometimes recommended. In western Europe, seeding rates range from 60–70 kg/ha for fiber cultivars. Recommendations for seeding rates for grain production vary widely, from 10–45 kg/ha. Densities for seed production for tall, European, dual-purpose cultivars are less than for short oilseed cultivars. Low plant densities, as commonly found in growing tall European cultivars for seed, may not suppress weed growth adequately, and under these circumstances resort to herbicides may pose a problem for those wishing to grow hempseed organically. Hemp requires about the same fertility as a high-yielding crop of wheat. Industrial hemp grows well in areas that corn produces high yields. Growing hemp may require addition of up to 110 kg/ha of nitrogen, and 40–90 kg/ha of potash. Hemp particularly requires good nitrogen fertilization, more so for seed production than fiber. Adding nitrogen when it is not necessary is deleterious to fiber production, so that knowledge of the fertility of soils being used is very important. Organic matter is preferably over 3.5%, phosphorus should be medium to high (>40 ppm), potassium should be medium to high (>250 ppm), sulfur good (>5,000 ppm), and calcium not in excess (<6,000 ppm).
Thank you for sharing your story. It is amazing the stories I have heard and the things you here the politicians debating over. The truth is out. They need to get over there guilty pride and pharmaceutical needs to be slapped down a few pegs. This is happening we just need to defend the corporations that back the oil, the pharma, any other corporation that doesn’t fight a health and balance model.
There is a general inverse relationship in the resin of Cannabis between the amounts of THC present and the amount of the other principal cannabinoid, CBD. Whereas most drug strains contain primarily THC and little or no CBD, fiber and oilseed strains primarily contain CBD and very little THC. CBD can be converted to THC by acid catalyzed cyclization, and so could serve as a starting material for manufacturing THC. In theory, therefore, low-THC cultivars do not completely solve the problem of drug abuse potential. In practice, however, the illicit drug trade has access to easier methods of synthesizing THC or its analogues than by first extracting CBD from non-drug hemp strains.
And the products on the shelf aren't all the same, Ward said. "There can be many, many different varieties, and if you're thinking about doing this for medical reasons, you want to find a trusted source and do your research," she said. "Where does that oil come from, and how confident can you be that you know the exact percentages of the different cannabinoids in the product?"
I have a cat with glaucoma diagnosed 1 month ago and on a prescribed eye drop 5ml Azopt Opht Susp. 1%. tid . The vet doesn’t think it will work for long. She is 17 and has heart murmur so thinks taking the eye would not be possible due to risk with murmur. Is it possible CBD will help that? How much liquid oil to give per lb? My CBD is 3.3MG/ML CBD in salmon oil. Farmacy brand. Trusted.
^ Jump up to: a b This paper begins with a history of hemp use and then describes how hemp was constructed as a dangerous crop in the U.S. The paper then discusses the potential of hemp as an alternative crop. Luginbuhl, April M. (2001). "Industrial hemp (Cannabis sativa L): The geography of a controversial plant". The California Geographer (PDF). 41. California Geographical Society. pp. 1–14. Retrieved 2013-03-28. Hemp contains less than 1% THC, or tetrahydrocannabinols, the psychoactive property in marijuana. In other words, smoking hemp cannot create a 'high.' ... The dense growth of hemp eliminates other weeds.... The best growing technique for hemp, planting 300 to 500 plants per square meter, also helps authorities easily tell the hemp from marijuana, which is a plant that is less densely cultivated. (Roulac 1997; 149).
The 1000mg potency would be best. The recommended dose is 1/2 the dropper 1-2 times a day. If you do not get the desired relief within a couple days you can slowly increase the dose as that is not harmful and essentially adds to the potency being absorbed. Our products metabolize differently in each individual; we do have customers whom take it in the morning, afternoon, and evening as they find that is what works best for them. The topical ointment may be beneficial as well as it contains menthol so it gives an instant relief while the CBD absorbs into the skin.
Phytocannabinoids are the herbal, natural and classical cannabinoids found in the cannabis plant. The glandular structure called the trichomes is where the concentrated viscous resin of the plant is found. There are over 60 cannabinoids that have been isolated from the plant. Tetrahydracannabinol (THC), Cannabidiol (CBD) and Cannabinol (CBN) are the most prevalent ones and have also been the most studied. Cannabidiol (CBD) accounts for up to 40% of the plant’s extract. It has been widely reported that CBD offers the greatest possible benefits of any of the extracts found in the plant. CBD can also be derived from hemp. Hemp and cannabis both contain large amounts of natural CBD, but hemp is naturally low in THC; thus, making it easier for manufacturers to create high CBD-infused products with low to non-existent THC levels. Since THC is (mostly) still illegal in the United States, most CBD items we carry are derived from hemp. Each CBD product varies in the amount of CBD and THC levels found in the product. No items we carry are over the legal limit of THC levels, which is 0.3%, according to U.S. Federal Law.

An important factor is the quality and purity of our CBD. We chose the Kentucky farm collective because of the quality of the hemp plants being grown under the Federal Farm Bill and in conjunction with the Kentucky Agricultural Department Hemp Pilot Program. There are very specific guidelines for planting, growing and the processing of the CBD isolate. As a result, the quality of the CBD produced from the whole plant is some of the purest available. We take great pride in providing our clients with an extremely pure, clean and high-quality product to those who desire CBD. Each and every product that leaves the facility is third-party tested to ensure consistency and quality.
Hemp, (Cannabis sativa), also called industrial hemp, plant of the family Cannabaceae cultivated for its fibre (bast fibre) or its edible seeds. Hemp is sometimes confused with the cannabis plants that serve as sources of the drug marijuana and the drug preparation hashish. Although all three products—hemp, marijuana, and hashish—contain tetrahydrocannabinol (THC), a compound that produces psychoactive effects in humans, the variety of cannabis cultivated for hemp has only small amounts of THC relative to that grown for the production of marijuana or hashish.
These mounting developments in the elicited a problem amongst cannabis cultivators across the US: decades of selectively breeding cannabis to achieve the maximum amount of THC for a strong high reduced the overall preponderance of CBD in cultivars across the country to trace lows. Essentially, CBD had been selectively bred out of existence across the country.
The isolation of CBD was recorded back on 1940 by two independent investigation groups. The group of Adams and colleges successfully isolated it from cannabis 1. At the same time Jacob and Todd successfully isolated the cannabidiol from indian hemp resin 2. But was not until 1963 that Mechoulam and Shyo discovered the chemical structure of the CBD and enlightening the comprehension of the nature of the cannabinoids 3. At the next year 1964 Gaoni and Mechoulam finally elucidated the chemical structure of the main psychoactive compound of cannabis the THC matching the starting point of the modern pharmacology of cannabis 4.
While most supplements have a single recommended dose, CBD is different. The amount of CBD you take depends on your doctor’s recommendations and your own research into how CBD will work for your unique needs. In general, it’s smart to start with a medium dose of CBD. This way, you can increase or decrease the dose as needed. In addition, it’s recommended to start with one half ML (half a dropper) of CBD oil, because you can always take more if needed.
Devinsky puts more weight behind the scientific advancements: In June, the FDA approved an epilepsy drug called Epidiolex, which contains a purified form of CBD oil. In controlled clinical trials, the drug was proven to reduce seizures in people with Dravet syndrome and Lennox-Gastaut syndrome — and it didn't produce as many of the unpleasant side-effects that come with other epilepsy medications.
When THC is consumed, it binds to CB1 receptors in the brain, which is what causes users to get high, while still providing certain health benefits. But CBD does not directly bind to these receptors and instead indirectly interacts with the CB2 receptors that are found mainly in the immune system, though they (along with CB1 receptors) are also found throughout the body.
There is certainly a need to utilize available germplasm sources in order to breed suitable cultivars for North America. A list of the 24 approved cultivars for the 2001 season in Canada is at www.hc-sc.gc.ca/hpb-dgps/therapeut/htmleng/hemp.html. Most of these are regulated by the European Organization of Economic Cooperation and Development (OECD). These cultivars are “approved” for use in Canada not on agricultural criteria, but merely on the basis that they meet the THC criterion. Indeed, most of these are unsuitable or only marginally suitable for Canada (Small and Marcus 2000), and only a very few Canadian cultivars to date have been created. In Canada, every acquisition of hemp grown at a particular place and time must be tested for THC content by an independent laboratory and, under the industrial hemp regulations, fields of hemp with more than 0.3% THC may require destruction (a slight degree of flexibility is generally exercised). Importation of experimental hemp lines (i.e. other than the approved cultivars) requires importation licenses (as well as phytosanitary clearance of the shipment by the Canadian Food Inspection Agency), and the importation licenses require an indication that the THC contents are low.
Karl W. Hillig, a graduate student in the laboratory of long-time Cannabis researcher Paul G. Mahlberg at Indiana University, conducted a systematic investigation of genetic, morphological, and chemotaxonomic variation among 157 Cannabis accessions of known geographic origin, including fiber, drug, and feral populations. In 2004, Hillig and Mahlberg published a chemotaxonomic analysis of cannabinoid variation in their Cannabis germplasm collection. They used gas chromatography to determine cannabinoid content and to infer allele frequencies of the gene that controls CBD and THC production within the studied populations, and concluded that the patterns of cannabinoid variation support recognition of C. sativa and C. indica as separate species, but not C. ruderalis. The authors assigned fiber/seed landraces and feral populations from Europe, Central Asia, and Turkey to C. sativa. Narrow-leaflet and wide-leaflet drug accessions, southern and eastern Asian hemp accessions, and feral Himalayan populations were assigned to C. indica. In 2005, Hillig published a genetic analysis of the same set of accessions (this paper was the first in the series, but was delayed in publication), and proposed a three-species classification, recognizing C. sativa, C. indica, and (tentatively) C. ruderalis. In his doctoral dissertation published the same year, Hillig stated that principal components analysis of phenotypic (morphological) traits failed to differentiate the putative species, but that canonical variates analysis resulted in a high degree of discrimination of the putative species and infraspecific taxa. Another paper in the series on chemotaxonomic variation in the terpenoid content of the essential oil of Cannabis revealed that several wide-leaflet drug strains in the collection had relatively high levels of certain sesquiterpene alcohols, including guaiol and isomers of eudesmol, that set them apart from the other putative taxa. Hillig concluded that the patterns of genetic, morphological, and chemotaxonomic variation support recognition of C. sativa and C. indica as separate species. He also concluded there is little support to treat C. ruderalis as a separate species from C. sativa at this time, but more research on wild and weedy populations is needed because they were underrepresented in their collection.
Over the last few years, the popularity of CBD has expanded dramatically. The Food and Drug Administration (FDA) recently approved CBD for the treatment of two severe forms of epilepsy, which makes it the first marijuana-derived drug to be approved at a federal level. One of the reasons that society has taken so well to CBD is because it doesn’t have any psychoactive effects. Essentially, you can enjoy all the therapeutic benefits of cannabis without getting high.

Hemp is plagued by bird predation, which take a heavy toll on seed production. The seeds are well known to provide extremely nutritious food for both wild birds and domestic fowl. Hunters and birdwatchers who discover wild patches of hemp often keep this information secret, knowing that the area will be a magnet for birds in the fall when seed maturation occurs. Increasingly in North America, plants are being established to provide habitat and food for wildlife. Hemp is not an aggressive weed, and certainly has great potential for being used as a wildlife plant. Of course, current conditions forbid such usage in North America.
Sublingual CBD Oils – also known as CBD Tinctures or CBD Hemp Oil – are the most popular type of CBD products, because of their high bioavailability and rapid absorption. There are many other kinds of products as well, including CBD edibles, CBD topicals, and even CBD-infused Coffee. CBD products have gained immense popularity in health and wellness circles thanks to their natural support of our endocannabinoid system (ECS).

Several animal studies have led researchers to believe that cannabis could reverse signs of aging in the brain. Aging mice treated with small daily doses of THC showed a reversal in cognitive decline. However, past studies on the effects of cannabis on human memory show less promising results. Still, with few viable treatments for dementia, medical marijuana is receiving increased attention in this area.

I've been waiting for weeks to receive this topical to see if I finally found a product that works and I'm so happy to say that I did! I've been dealing with knee pain that my doctor has not been able to officially diagnose and treat and it's extremely painful. This is the first product that I've tried that actually relieves most of the pain and pressure so I can continue to workout and stand without being in so much pain. Thank you for creating such an amazing product!
Edible cannabis, however, is quickly making up ground as a go-to method for consuming medical marijuana. Indeed, some states with legal medical marijuana laws still forbid smoking marijuana. Instead, medical forms of the drug are only available in pill or capsule form. Oils and tinctures, which are made from extracting cannabinoids from herbaceous material, are also commonly prescribed in the form of cannabis edibles.
Fibres are obtained by subjecting the stalks to a series of operations—including retting, drying, and crushing—and a shaking process that completes separation from the woody portion, releasing the long, fairly straight fibre, or line. The fibre strands, usually over 1.8 metres (5.8 feet) long, are made of individual cylindrical cells with an irregular surface. The fibre, longer and less flexible than flax, is usually yellowish, greenish, or a dark brown or gray and, because it is not easily bleached to sufficiently light shades, is rarely dyed. It is strong and durable and is used for cordage—e.g., twine, yarn, rope, cable, and string—and for artificial sponges and such coarse fabrics as sacking (burlap) and canvas. In Italy some hemp receives special processing, producing whitish colour and attractive lustre, and is used to make fabric similar to linen.

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.

Hemp seeds have an attractive nutty taste, and are now incorporated into many food preparations (Fig. 34), often mimicking familiar foods. Those sold in North America include nutritional (granola-type) or snack bars, “nut butters” and other spreads, bread, pretzels, cookies, yogurts, pancakes, porridge, fruit crumble, frozen dessert (“ice cream”), pasta, burgers, pizza, salt substitute, salad dressings, mayonnaise, “cheese,” and beverages (“milk,” “lemonade,” “beer,” “wine,” “coffee nog”). Hemp seed is often found canned or vacuum-packed (Fig. 35). Alcoholic beverages made with hemp utilize hempseed as a flavorant. Hemp food products currently have a niche market, based particularly on natural food and specialty food outlets.
As described in an article on Labroots, “Scientists discovered the brain’s opiate receptor in 1973, but it was not until 1988 in a government-funded study at the St. Louis University School of Medicine that Allyn Howlett and William Devane determined that the mammalian brain has receptor sites that respond to compounds found in cannabis. These receptors … turned out to be the most abundant type of neurotransmitter receptor in the brain.”
A CNN program that featured Charlotte's Web cannabis in 2013 brought increased attention to the use of CBD in the treatment of seizure disorders. Since then, 16 states have passed laws to allow the use of CBD products with a doctor's recommendation (instead of a prescription) for treatment of certain medical conditions. This is in addition to the 30 states that have passed comprehensive medical cannabis laws, which allow for the use of cannabis products with no restrictions on THC content. Of these 30 states, eight have legalized the use and sale of cannabis products without requirement for a doctor's recommendation.
In Peru the central business district is San Isidro, in Lima, which hosts the majority of Peru's financial industry headquarters. Although still a largely residential district, the commercial and business activity located in or in the vicinity of the area defined by avenues Camino Real, Javier Prado Este, República de Panamá and Aramburú is highly regarded as Peru's financial and corporate heart. It has a permanent population of around 63,000 inhabitants and, during weekday business hours, a floating population that exceeds 700,000 daily commuters from other districts of Lima. San Isidro is served by three stations of El Metropolitano, Lima's bus rapid transit system: Estación Javier Prado, Estación Canaval y Moreyra (with over 16,000 daily passengers) and Estación Aramburú.
There is still a lot we don’t know about CBD. More accurately, we know pretty much nothing definitive about CBD because of the bureaucratic minefield that is the U.S. drug classification system. Under federal law, marijuana is a schedule 1 drug — putting it on the same level as LSD, ecstasy, and heroin. Even if it won’t get someone high, a non-hemp CBD product might still be technically illegal under federal law.
The psychoactive effects of cannabis are known to have a triphasic nature. Primary psychoactive effects include a state of relaxation, and to a lesser degree, euphoria from its main psychoactive compound, tetrahydrocannabinol. Secondary psychoactive effects, such as a facility for philosophical thinking, introspection and metacognition have been reported among cases of anxiety and paranoia. Finally, the tertiary psychoactive effects of the drug cannabis, can include an increase in heart rate and hunger, believed to be caused by 11-OH-THC, a psychoactive metabolite of THC produced in the liver.
CBD and dogs go together well, according to a lot of studies and veterinarians. CBD can be given to dogs in the form of CBD pill, liquid CBD oil for dogs, or CBD dog treats. There is no difference between these three and it mostly depends on convenience and your dog's preference; however, it's possible that CBD oil for dogs may have better absorption rates.
About 9% of those who experiment with marijuana eventually become dependent according to DSM-IV (1994) criteria. A 2013 review estimates daily use is associated with a 10-20% rate of dependence. The highest risk of cannabis dependence is found in those with a history of poor academic achievement, deviant behavior in childhood and adolescence, rebelliousness, poor parental relationships, or a parental history of drug and alcohol problems. Of daily users, about 50% experience withdrawal upon cessation of use (i.e. are dependent), characterized by sleep problems, irritability, dysphoria, and craving. Cannabis withdrawal is less severe than withdrawal from alcohol.
Of the 20 known amino acids, hemp supplies them all, including the essential ones the body can’t produce, known as EAAs. About 65 percent of the protein in hemp seeds is edestin, a globulin protein that aids in digestion, similar to the globulin found in human blood plasma, and hemp seeds are the only place they’re found. The other third is made up of the protein albumin.

Australia's National Cannabis Prevention and Information Centre (NCPIC) states that the buds (flowers) of the female cannabis plant contain the highest concentration of THC, followed by the leaves. The stalks and seeds have "much lower THC levels". The UN states that leaves can contain ten times less THC than the buds, and the stalks one hundred times less THC.
Due to Berlin's history of division during the Cold War, the city contains central business districts both in West (Kurfürstendamm) and East Berlin (Alexanderplatz), as well as a newly-built business centre near Potsdamer Platz. The city's historic centre — the location of the Reichstag building, as well as the Brandenburg gate and most federal ministries — was largely abandoned when the Berlin Wall cut through the area. Only after the reunification with the redevelopment of Potsdamer Platz, and the construction of numerous shopping centers, government ministries, embassies, office buildings and entertainment venues, was the area revived.
One of the first bioprospecting groups that attempted to implement the goals and guidelines of the CBD was a collaboration between the pharmaceutical firm Merck & Company and Costa Rica's Instituto Nacional de Biodiversidad (INBio), a private, nonprofit conservation and research group, INBio agreed to provide Merck with a limited number of plants, fungi, and other samples from Costa Rica's protected areas for scientific and commercial evaluation.
Marijuana (Cannabis sativa) contains bioactive cannabinoids, with δ-9-tetrahydrocannabinol being the primary active ingredient responsible for the pleasurable subjective effects. The primary route of administration is smoking, although oral administration is common, with the inclusion of marijuana in baked goods or extraction in herbal tea preparations. Although the marijuana has been legalized or decriminalized in many locales, it is still predominantly illegal, and the ramifications of chronic use include incarceration. Marijuana addiction is a common condition, for which treatment may be sought for teenagers and others. Like other drugs of abuse, marijuana leads to acute alterations in dopamine release, with reductions in extracellular dopamine levels during withdrawal; recurrent chronic use can result in changes in components of the endogenous opioid system.
Cannabidiol has been found to act as an antagonist of GPR55, a G protein-coupled receptor and putative cannabinoid receptor that is expressed in the caudate nucleus and putamen in the brain. It has also been found to act as an inverse agonist of GPR3, GPR6, and GPR12. Although currently classified as orphan receptors, these receptors are most closely related phylogenetically to the cannabinoid receptors. In addition to orphan receptors, CBD has been shown to act as a serotonin 5-HT1A receptor partial agonist, and this action may be involved in its antidepressant, anxiolytic, and neuroprotective effects. It is an allosteric modulator of the μ- and δ-opioid receptors as well. The pharmacological effects of CBD have additionally been attributed to PPARγ agonism and intracellular calcium release.
The leaves have a peculiar and diagnostic venation pattern that enables persons poorly familiar with the plant to distinguish a cannabis leaf from unrelated species that have confusingly similar leaves (see illustration). As is common in serrated leaves, each serration has a central vein extending to its tip. However, the serration vein originates from lower down the central vein of the leaflet, typically opposite to the position of, not the first notch down, but the next notch. This means that on its way from the midrib of the leaflet to the point of the serration, the vein serving the tip of the serration passes close by the intervening notch. Sometimes the vein will actually pass tangent to the notch, but often it will pass by at a small distance, and when that happens a spur vein (occasionally a pair of such spur veins) branches off and joins the leaf margin at the deepest point of the notch. This venation pattern varies slightly among varieties, but in general it enables one to tell Cannabis leaves from superficially similar leaves without difficulty and without special equipment. Tiny samples of Cannabis plants also can be identified with precision by microscopic examination of leaf cells and similar features, but that requires special expertise and equipment.
In this edition of Cannabis Conversations, Project CBD Director, Martin A. Lee, discusses the benefits of CBD, the "entourage effect" and the microbiome with Dr. Ethan Russo. A neurologist, scientist, and widely published author, Dr. Russo is currently the director of research and development at the International Cannabis and Cannabinoids Institute in Prague (www.icci.science).
