Karl W. Hillig, a graduate student in the laboratory of long-time Cannabis researcher Paul G. Mahlberg[77] 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.[52] 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.[55] 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.[78] 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.[79] 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.
The question of whether heteromorphic sex chromosomes are indeed present is most conveniently answered if such chromosomes were clearly visible in a karyotype. Cannabis was one of the first plant species to be karyotyped; however, this was in a period when karyotype preparation was primitive by modern standards (see History of Cytogenetics). Heteromorphic sex chromosomes were reported to occur in staminate individuals of dioecious "Kentucky" hemp, but were not found in pistillate individuals of the same variety. Dioecious "Kentucky" hemp was assumed to use an XY mechanism. Heterosomes were not observed in analyzed individuals of monoecious "Kentucky" hemp, nor in an unidentified German cultivar. These varieties were assumed to have sex chromosome composition XX.[31] According to other researchers, no modern karyotype of Cannabis had been published as of 1996.[32] Proponents of the XY system state that Y chromosome is slightly larger than the X, but difficult to differentiate cytologically.[33]
Designed to provide the optimum absorption of CBD into the blood stream by employing a patented slow release delivery system. It’s well accepted that CBD is most effective when taken sublingualy, however most oils when taken in this way are swallowed and broken down by your body. The Gel-Tab™. is placed under the tongue and the CBD is slowly absorbed resulting in higher rates of CBD being absorbed than what would be achieved with a normal oil
Mainly what they look for in drug test is THC. Hemp contains only very minuscule amounts of THC. You cannot get high off of hemp. It is impossible. You would have to smoke or eat a boat load of hemp to even remotely get a buzz. A person could not ingest that much hemp, and a person would die of smoke inhalation before smoking enough to achieve a buzz. So hemp does not contain enough THC to show up on a drug screening. I hope this information helps you.
CBD interacts with the body through the endogenous cannabinoid system (ECS) or endocannabinoid system. First discovered in the late 1980’s, the endocannabinoid system regulates the body’s homeostasis, or general state of balance, impacting such functions as mood, sleep, appetite, hormone regulation, and pain and immune response. Like an acrobat on a highwire, as the environment around us impacts our normal balance, the endocannabinoid system “corrects” by mediating our body’s reaction to keep us level.

The vegetable oils have been classified by “iodine value” as drying (120–200), semi-drying (100–120), and non-drying (80–100), which is determined by the degree of saturation of the fatty acids present (Raie et al. 1995). Good coating materials prepared from vegetable oil depend on the nature and number of double bonds present in the fatty acids. Linseed oil, a drying oil, has a very high percentage of linolenic acid. Hempseed oil has been classified as a semi-drying oil, like soybean oil, and is therefore more suited to edible than industrial oil purposes. Nevertheless hemp oil has found applications in the past in paints, varnishes, sealants, lubricants for machinery, and printing inks. However, such industrial end uses are not presently feasible as the oil is considered too expensive (de Guzman 2001). Larger production volumes and lower prices may be possible, in which case hemp oil may find industrial uses similar to those of linseed (flax), soybean, and sunflower oils, which are presently used in paints, inks, solvents, binders, and in polymer plastics. Hemp shows a remarkable range of variation in oil constituents, and selection for oilseed cultivars with high content of valued industrial constituents is in progress.
After seasonal harvests of specific cultivars, these high-CBD hemp crops are put through a specialized solvent-free extraction process to yield a hemp oil that is naturally high in cannabidiol. This pure hemp extract is then tested for safety, quality, and cannabinoid content before being exported to our processing facilities in the United States. Importing any cannabis or hemp product into the United States is a complicated and serious task, so we leave nothing to chance before our high-CBD hemp oil makes its journey across the Atlantic Ocean.
"We still don't fully understand all of the mechanisms involved in CBD's actions," says Marcel Bonn-Miller, Ph.D, who studies CBD and its effects, primarily on PTSD. "We know some pieces but definitely not the whole story at this point. A lot of our understanding of the many potential benefits of CBD is rooted in work either on the cellular level or in preclinical models with rodents."
Without arguing the merits of the above contentions, we point out that the legitimate use of hemp for non-intoxicant purposes has been inhibited by the continuing ferocious war against drug abuse. In this atmosphere, objective analysis has often been lacking. Unfortunately both proponents and opponents have tended to engage in exaggeration. Increasingly, however, the world is testing the potential of hemp in the field and marketplace, which surely must be the ultimate arbiters. De Guzman (2001), noting the pessimistic USDA report, observed that “Nevertheless, others point to the potential of [the] market. Hemp products have a growing niche market of their own, and the market will remain healthy and be well supported with many competing brands.”
In the meantime, some physicians are forging ahead — and cashing in. Joe Cohen is a doctor at Holos Health, a medical marijuana clinic in Boulder. I asked him what CBD is good for, and he read me a long list of conditions: pain, inflammation, nausea, vomiting, intestinal cramping, anxiety, psychosis, muscle spasms, hyperactive immune systems, nervous system degeneration, elevated blood sugar and more. He also claimed that CBD has anti-cancer properties and can regenerate brain cells and reduce the brain’s levels of amyloid beta — a kind of protein that’s been linked to Alzheimer’s disease. I asked for references, noting that most of these weren’t listed in the Academies report or a similar review published in the Journal of the American Medical Association. “I think you just have to Google search it,” he said. It’s true that a preliminary study found hints that cannabinoids might reduce beta amyloid proteins in human brain cells, but the study was done in cells grown in a lab, not in people. As for cancer, the FDA sent warning letters last year to four companies that were selling products that claimed to “prevent, diagnose, treat or cure” cancer.
Medical marijuana refers to the use of the Cannabis plant as a physician-recommended herbal therapy as well as synthetic[181] THC and cannabinoids. So far, the medical use of cannabis is legal only in a limited number of territories, including Canada,[37] Belgium, Australia, the Netherlands, Spain, and many U.S. states. This usage generally requires a prescription, and distribution is usually done within a framework defined by local laws. There is evidence supporting the use of cannabis or its derivatives in the treatment of chemotherapy-induced nausea and vomiting, neuropathic pain, and multiple sclerosis. Lower levels of evidence support its use for AIDS wasting syndrome, epilepsy, rheumatoid arthritis, and glaucoma.[74]
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]
In 1951, Congress passed the Boggs Act, which for the first time included Cannabis with narcotic drugs. In 1970, with the passage of the Controlled Substances Act, marijuana was classified by Congress as a Schedule I drug. Drugs in Schedule I are distinguished as having no currently accepted medicinal use in the United States. Other Schedule I substances include heroin, LSD, mescaline, and methaqualone.
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.

"They nailed this story every step of the way, even when the company itself seemed to be totally clueless — or perhaps something even worse — about its own prospects," he said. "Which is why you do need to take your cue from these two gentlemen and wait until the real problems they say are solved before you get bullish. And they sure aren't there yet."

Another study examined the effects of a plant extract with controlled cannabinoid content in an oromucosal spray. In a multicenter, double-blind, placebo-controlled study, the THC:CBD nabiximols extract and THC extract alone were compared in the analgesic management of patients with advanced cancer and with moderate-to-severe cancer-related pain. Patients were assigned to one of three treatment groups: THC:CBD extract, THC extract, or placebo. The researchers concluded that the THC:CBD extract was efficacious for pain relief in advanced cancer patients whose pain was not fully relieved by strong opioids.[52] In a randomized, placebo-controlled, graded-dose trial, opioid-treated cancer patients with poorly controlled chronic pain demonstrated significantly better control of pain and sleep disruption with THC:CBD oromucosal spray at lower doses (1–4 and 6–10 sprays/day), compared with placebo. Adverse events were dose related, with only the high-dose group (11–16 sprays/day) comparing unfavorably with the placebo arm. These studies provide promising evidence of an adjuvant analgesic effect of THC:CBD in this opioid-refractory patient population and may provide an opportunity to address this significant clinical challenge.[53] An open-label extension study of 43 patients who had participated in the randomized trial found that some patients continued to obtain relief of their cancer-related pain with long-term use of the THC:CBD oromucosal spray without increasing their dose of the spray or the dose of their other analgesics.[54]

Perhaps the most important difference between hemp and marijuana is that marijuana – no pun intended – has a high delta-9 tetrahydrocannabinol content, or THC, which supplies the sought-after psychotropic effect, but it’s low in cannabidiol content, or CBD, which has medicinal properties. Hemp is just the opposite, being typically high in CBD and low in THC, meaning it’s not going to get anybody stoned. In fact, clinical studies show that CBD blocks the effect of THC in the nervous system. Both THC and CBD contain cannabinoid, but it’s the amount that needs to examined, because CBD is currently a Schedule 1 controlled substance. That means that at present, there’s currently no permissible medical protocol in the US.
Recent European Commission proposals to change its subsidy regime for hemp contained the following negative evaluation of hemp seed: “The use of hemp seed ... would, however, even in the absence of THC, contribute towards making the narcotic use of cannabis acceptable... In this light, subsidy will be denied producers who are growing grain for use in human nutrition and cosmetics.”

"Industrial hemp" means a fiber or oilseed crop, or both, that is limited to types of the plant Cannabis sativa L. having no more than three-tenths of 1 percent tetrahydrocannabinol (THC) contained in the dried flowering tops, whether growing or not; the seeds of the plant; the resin extracted from any part of the plant; and every compound, manufacture, salt, derivative, mixture, or preparation of the plant, its seeds or resin produced therefrom.

“Folks at the various state Departments of Agriculture are so excited to bring in hemp – excited to introduce any crop, really, and especially to reintroduce this extraordinarily versatile one,” Beckerman said. “But they’re not experts; they’re learning like anybody else. So getting in there, looking at proposed legislation and rules to make sure [proposals] actually make sense for the crop – on an agronomic level, on a regulatory level – and monitoring changes to that legislation, regulation, or industry, is common sense.” She went on,
When Brandon Krenzler’s daughter Mykayla was diagnosed with a form of childhood leukemia in 2012 at the age of seven, he began researching medical marijuana products that might ease her symptoms and blogging about the results. The next year, he received some samples of Real Scientific Hemp Oil, which he administered to Mykayla. But the oil made her sick.

Our custom-designed cultivation facility was built with quality in mind. Instead of a vast, open-air facility we opted to build smaller, laboratory-grade growing rooms. This allows for optimal conditions for each strain, and guarantees that we always have a steady supply of fresh stock. We also follow strict quality control procedures to ensure purity, quality, and customer satisfaction.
The 113th Congress made significant changes to U.S. policies regarding industrial hemp during the omnibus farm bill debate. The Agricultural Act of 2014 (P.L. 113-79) provided that certain research institutions and state departments of agriculture may grow industrial hemp, as part of an agricultural pilot program, if allowed under state laws where the institution or state department of agriculture is located. The FY2015 appropriations (P.L. 113-235) further blocked federal law enforcement authorities from interfering with state agencies, growers, and agricultural research. (From "Hemp as an agricultural commodity," Congressional Research Service)
The term kief refers to the sticky, bulbous crystalline formations on the tip of a gland called a “trichome.” Trichomes are external resin glands packed with the chemicals that give marijuana its flavors and smells, called “terpenes.” They also contain high concentrations of cannabinoids. These chemicals which interact with our body to produce marijuana’s signature effects.
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.
The good news is that most of the official research done on CBD oil has shown that there are very few negative side effects from using it. However, CBD is not without some side effects. Most notably, in the clinical studies for epilepsy, sedation was one of the more common side effects. Decreased appetite and diarrhea were also seen in some patients. Depending on what other medicines they are taking, certain patients may need to have periodic blood tests to check on liver function.
The more recently House-approved version, which introduced the well-publicized provision affecting up to two million Supplemental Nutrition Assistance Program (SNAP) recipients, doesn't take such steps to remove federal barriers around hemp. It also stipulates that anyone with a felony drug conviction would be barred indefinitely from participating in federal or state hemp programs.

Put simply, “indica” strains are those associated with a strong body-high, feelings of sedation and relaxation. For this reason, indicas are often thought of as the “heavier” strains of cannabis, offering stronger highs that impact the whole body. They’re popular among marijuana users as pain relieving and sleep-inducing strains. Indicas are especially popular among medical cannabis patients.
Nabiximols (Sativex), a Cannabis extract with a 1:1 ratio of THC:CBD, is approved in Canada (under the Notice of Compliance with Conditions) for symptomatic relief of pain in advanced cancer and multiple sclerosis.[17] Canada, New Zealand, and some countries in Europe also approve nabiximols for spasticity of multiple sclerosis, a common symptom that may include muscle stiffness, reduced mobility, and pain, and for which existing therapy is unsatisfactory.
Figuring out how much CBD oil to take can feel like trying to navigate through a complicated maze. The sheer volume of CBD brands on the market can create confusion for consumers, and when you take a closer look, it’s not difficult to understand why. Not only do vendors use different source materials (CBD-rich cannabis vs. industrial hemp, different strains, etc.), but they also implement different extraction techniques .

Given its name, you might assume THCV shares psychoactive powers with its potent counterpart, THC. In reality, this cannabinoid is more like a cross between CBD and THC. From the former, it takes its modulating powers. Acting like THC “lite,” THCV like CBD can dampen the effects of a strong high. Yet at higher doses, THCV kicks into a psychoactive stimulant in its own right.
In short, Cannabidiol – or CBD – is a cannabis compound that has many therapeutic benefits. Usually extracted from the leaves and flowers of hemp plants – though marijuana can also be a source – CBD oil is then incorporated into an array of marketable products. These products vary from the most common, like sublingual oils and topical lotions, to the less common (think CBD lattes). Basically, if you can dream it, you can buy it.
Out of the 17 states that have passed CBD-only laws, five— Missouri, Florida, Mississippi, Louisiana, and Texas—would also establish licensed cultivation centers to grow high-CBD strains of cannabis, which could be turned into oils and other CBD products. This would cut down on the demand for CBD oil from unregulated manufacturers abroad. Even then, though, impediments remain. In Missouri, for example, two neurologists recently refused to prescribe CBD oil for an eight- year-old boy suffering from seizures, citing concerns over federal law and the safety of non-FDA approved products.
In recent decades, the neurobiology of cannabinoids has been analyzed.[12-15] The first cannabinoid receptor, CB1, was identified in the brain in 1988. A second cannabinoid receptor, CB2, was identified in 1993. The highest expression of CB2 receptors is located on B lymphocytes and natural killer cells, suggesting a possible role in immunity. Endogenous cannabinoids (endocannabinoids) have been identified and appear to have a role in pain modulation, control of movement, feeding behavior, mood, bone growth, inflammation, neuroprotection, and memory.[16]
Lewis has even built his own machine to process the hemp. Using a Patagonia grant, he created a piece of equipment called a “break”, which incorporates design details borrowed from early European flax roller breaks. Lewis’s invention is a one-of-a-kind machine. It works by separating the hemp’s woody core from the fibers which are used in textiles. According to Lewis, the highest quantity of finished hemp fiber processed in a day using the machine is around 60lbs – which means about 600lbs of raw material. A newer version of the break, which Lewis is currently working on, will have a capacity to produce about 2000lbs per day of raw material.
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.[44]
