Germplasm for the improvement of hemp is vital for the future of the industry in North America. However, there are no publicly available germplasm banks housing C. sativa in North America. The hundreds of seed collections acquired for Small’s studies (reviewed in Small 1979) were destroyed in 1980 because Canadian government policy at that time envisioned no possibility that hemp would ever be developed as a legitimate crop. An inquiry regarding the 56 United States Department of Agriculture hemp germplasm collections supplied to and grown by Small and Beckstead (1973) resulted in the reply that there are no remaining hemp collections in USDA germplasm holdings, and indeed that were such to be found they would have to be destroyed. While hemp has been and still is cultivated in Asia and South America, it is basically in Europe that germplasm banks have made efforts to preserve hemp seeds. The Vavilov Institute of Plant Research in St. Petersburg, Russia has by far the largest germplasm collection of hemp of any public gene bank, with about 500 collections. Detailed information on the majority of hemp accessions of the Vavilov Institute can be found in Anon. (1975). Budgetary problems in Russia have endangered the survival of this invaluable collection, and every effort needs to be made to find new funding to preserve it. Maintenance and seed generation issues for the Vavilov hemp germplasm collection are discussed in a number of articles in the Journal of the International Hemp Association (Clarke 1998b; Lemeshev et al. 1993, 1994). The Gatersleben gene bank of Germany, the 2nd largest public gene bank in Europe, has a much smaller Cannabis collection, with less than 40 accessions (detailed information on the hemp accessions of the Gatersleben gene bank are available at fox-serv.ipk-gatersleben.de/). Because hemp is regaining its ancient status as an important crop, a number of private germplasm collections have been assembled for the breeding of cultivars as commercial ventures (de Meijer and van Soest 1992; de Meijer 1998), and of course these are available only on a restricted basis, if at all.
In an in vivo model using severe combined immunodeficient mice, subcutaneous tumors were generated by inoculating the animals with cells from human non-small cell lung carcinoma cell lines. Tumor growth was inhibited by 60% in THC-treated mice compared with vehicle-treated control mice. Tumor specimens revealed that THC had antiangiogenic and antiproliferative effects. However, research with immunocompetent murine tumor models has demonstrated immunosuppression and enhanced tumor growth in mice treated with THC.[24,25]
Senate Majority Leader Mitch McConnell (R-KY) is guaranteeing that the 2018 Farm Bill will include his industrial hemp legalization provision after the Senate and House reach a compromise—ideally by the end of the year. “If there’s a Farm Bill, it’ll be in there, I guarantee that,” he told reporters on Friday. McConnell said he’s visited … Continue reading Mitch McConnell Guarantees Industrial Hemp Legalization

The downsides of graphene are its dwindling sources and costly process to mine and import from rural areas in China and India. Hemp, however, can be grown in almost any terrain or country, and produces hemp bast, the key material used to replace graphene, as a waste byproduct of hemp processing. According to Mitlin’s research, hemp processing is 1,000 times cheaper than graphene processing.
Ten years ago hemp cultivation was illegal in Germany, England, Canada, Australia, and other countries. Essential to overcoming governmental reluctance in each country was the presentation of an image that was business-oriented, and conservative. The merits of environmentalism have acquired some political support, but unless there is a reasonable possibility that hemp cultivation is perceived as potentially economically viable, there is limited prospect of having anti-hemp laws changed. Strong support from business and farm groups is indispensable; support from pro-marijuana interests and what are perceived of as fringe groups is generally counterproductive. It is a combination of prospective economic benefit coupled with assurance that hemp cultivation will not detrimentally affect the enforcement of marijuana legislation that has led most industrially advanced countries to reverse prohibitions against growing hemp. Should the US permit commercial hemp cultivation to resume, it will likely be for the same reasons.
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.
Smoking marijuana is hands down the most widely used method of consuming cannabis. It’s also the simplest: a rolling paper and some dried marijuana flower are all you need. Other, more technological methods of smoking marijuana may be rising in popularity. But for many people, the social experience of passing weed around with some friends is what cannabis is all about.
Today, you’ll find nutty-tasting (hull-less) hemp seeds and their oils baked in breads, cookies, and cakes, blended in smoothies, or tossed into quinoa and pasta dishes, burgers, pizza, vegetables sautés, soups, salads, oatmeal, yogurt, trail mix, and salad dressings. It’s a niche market, with a growing number of specialty outlets due to a growing understanding of this food’s nutritional benefits.

In a new short film produced by Patagonia, Harvesting Liberty, Michael Lewis, a veteran and hemp grower in Kentucky, shares his encounter with the DEA. In 2014, after the passage of the Farm Bill, Lewis was keen to plant hemp in Kentucky. “[But] the DEA didn’t agree that we had a right to plant the crop. They said they would arrest us,” he says in the film. The matter ended up in the Louisville court, where a judge sided with the farmers. “[We] took our seeds up, got them registered and certified, and threw them into the ground before anyone could change their mind,” Lewis says.
Because cannabinoid receptors, unlike opioid receptors, are not located in the brainstem areas controlling respiration, lethal overdoses from Cannabis and cannabinoids do not occur.[1-4] However, cannabinoid receptors are present in other tissues throughout the body, not just in the central nervous system, and adverse effects include tachycardia, hypotension, conjunctival injection, bronchodilation, muscle relaxation, and decreased gastrointestinal motility.
Cannabis is used in three main forms: marijuana, hashish and hash oil. Marijuana is made from dried flowers and leaves of the cannabis plant. It is the least potent of all the cannabis products and is usually smoked or made into edible products like cookies or brownies (see Factsheet: Marijuana Edibles). Hashish is made from the resin (a secreted gum) of the cannabis plant. It is dried and pressed into small blocks and smoked. It can also be added to food and eaten. Hash oil, the most potent cannabis product, is a thick oil obtained from hashish. It is also smoked.
The basic commercial options for growing hemp in North America is as a fiber plant, an oilseed crop, or for dual harvest for both seeds and fiber. Judged on experience in Canada to date, the industry is inclined to specialize on either fiber or grain, but not both. Hemp in our opinion is particularly suited to be developed as an oilseed crop in North America. The first and foremost breeding goal is to decrease the price of hempseed by creating more productive cultivars. While the breeding of hemp fiber cultivars has proceeded to the point that only slight improvements can be expected in productivity in the future, the genetic potential of hemp as an oilseed has scarcely been addressed. From the point of view of world markets, concentrating on oilseed hemp makes sense, because Europe has shown only limited interest to date in developing oilseed hemp, whereas a tradition of concentrating on profitable oilseed products is already well established in the US and Canada. Further, China’s supremacy in the production of high-quality hemp textiles at low prices will be very difficult to match, while domestic production of oilseeds can be carried out using technology that is already available. The present productivity of oilseed hemp—about 1 t/ha under good conditions, and occasional reports of 1.5 to 2 t/ha, is not yet sufficient for the crop to become competitive with North America’s major oilseeds. We suggest that an average productivity of 2 t/ha will be necessary to transform hempseed into a major oilseed, and that this breeding goal is achievable. At present, losses of 30% of the seed yields are not uncommon, so that improvements in harvesting technology should also contribute to higher yields. Hemp food products cannot escape their niche market status until the price of hempseed rivals that of other oilseeds, particularly rapeseed, flax, and sunflower. Most hemp breeding that has been conducted to date has been for fiber characteristics, so that there should be considerable improvement possible. The second breeding goal is for larger seeds, as these are more easily shelled. Third is breeding for specific seed components. Notable are the health-promoting gamma-linolenic acid; improving the amino acid spectrum of the protein; and increasing the antioxidant level, which would not only have health benefits but could increase the shelf life of hemp oil and foods.
Cultivated in at least 30 countries, monikers for the hemp plant often allude to its origin or use, such as Manila hemp (abacá, Musa textilis), sisal hemp (Agave sisalana), Indian hemp (Apocynumcannabinum) and New Zealand hemp (Phormiumtenax). Worldwide, hemp seed production alone has soared from around 33,000 metric tons in the late ’90s to more than 100,000 metric tons annually between 2005 and 2011.
Acute effects may include anxiety and panic, impaired attention, and memory (while intoxicated), an increased risk of psychotic symptoms, and possibly an increased risk of accidents if a person drives a motor vehicle while intoxicated. Short-term cannabis intoxication can hinder the mental processes of organizing and collecting thoughts. This condition is known as temporal disintegration. Psychotic episodes are well-documented and typically resolve within minutes or hours. There have been few reports of symptoms lasting longer.
State policymakers have taken action to address various policy issues — the definition of hemp, licensure of growers, regulation and certification of seeds, state-wide commissions and legal protection of growers. At least 41 states have passed legislation related to industrial hemp, such as defining hemp and removing barriers, and at least 39 states have allowed for hemp cultivation and production programs. Some states establishing these programs require a change in federal laws or a waiver from the DEA prior to implementation.

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.
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.
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.
A systematic review assessing 19 studies that evaluated premalignant or malignant lung lesions in persons 18 years or older who inhaled Cannabis concluded that observational studies failed to demonstrate statistically significant associations between Cannabis inhalation and lung cancer after adjusting for tobacco use. In the review of the published meta-analyses, the National Academies of Sciences, Engineering, and Medicine (NASEM) report concluded that there was moderate evidence of no statistical association between Cannabis smoking and the incidence of lung cancer.
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).
Hemp jewelry is the product of knotting hemp twine through the practice of macramé. Hemp jewellery includes bracelets, necklaces, anklets, rings, watches and other adornments. Some jewellery features beads made from crystals, glass, stone, wood and bones. The hemp twine varies in thickness and comes in a variety of colors. There are many different stitches used to create hemp jewellery, however, the half knot and full knot stitches are most common.
