Thermal Insulation. Thermal insulation products (Fig. 20, 21) are the third most important sector of the hemp industry of the EU. These are in very high demand because of the alarmingly high costs of heating fuels, ecological concerns about conservation of non-renewable resources, and political-strategic concerns about dependence on current sources of oil. This is a market that is growing very fast, and hemp insulation products are increasing in popularity. In Europe, it has been predicted that tens of thousands of tonnes will be sold by 2005, shared between hemp and flax (Karus et al. 2000).
Cannabis use for medicinal purposes dates back at least 3,000 years.[1-5] It was introduced into Western medicine in 1839 by W.B. O’Shaughnessy, a surgeon who learned of its medicinal properties while working in India for the British East India Company. Its use was promoted for reported analgesic, sedative, anti-inflammatory, antispasmodic, and anticonvulsant effects.
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).
There are ways to strain dangerous contaminants out of raw hemp paste. And most companies stand behind their quality and safety procedures. “We continuously test all our products ... to ensure our consumers get the levels of natural constituents they expect from the quality hemp stalk oil they purchase,” HempMedsPx states on its web site. “Additionally, all our products are tested for safety, to ensure there are no solvents, heavy metals, or other potentially harmful materials in our oil. Because we take these steps, we are always confident in our products, and you can be too.”
CDFA has not yet proposed any regulations regarding industrial hemp. Regulations pertaining to cultivation will be developed in conjunction with the Industrial Hemp Advisory Board, and will be promulgated through the regular rulemaking process in accordance with the California Administrative Procedures Act. CDFA will notify the public via our electronic mailing list as regulations are posted and available for public comment.
As of March 2016, more than half of the 50 states have laws that allow for some hemp production, according to this chart. Yet, many states, such as California, where Jungmaven is based, will only allow for industrial hemp cultivation when federal law coincides with state law. That is, when Congress passes a bill permitting industrial hemp across the US. Currently, Jungmann imports his hemp from China, but he’s confident Congress will pass the bill legalizing industrial farming of hemp in July.
Cannabis, especially the cannabinoid CBD, has also demonstrated its abilities as a powerful anti-convulsant. This property is what accounts for cannabis’ ability to reduce the severity and frequency of seizures, especially for people with epilepsy. In the United States, epilepsy is the most widely adopted qualifying condition for medical cannabis use, especially for children.

One of the most curious uses of hemp is as a fence to prevent pollen transfer in commercial production of seeds. Isolation distances for ensuring that seeds produced are pure are considerable for many plants, and often impractical. At one point in the 1980s, the only permitted use of hemp in Germany was as a fence or hedge to prevent plots of beets being used for seed production from being contaminated by pollen from ruderal beets. The high and rather inpenetrable hedge that hemp can produce was considered unsurpassed by any other species for the purpose. As well, the sticky leaves of hemp were thought to trap pollen. However, Saeglitz et al. (2000) demonstrated that the spread of beet pollen is not effectively prevented by hemp hedges. Fiber (i.e. tall) cultivars of hemp were also once used in Europe as wind-breaks, protecting vulnerable crops against wind damage. Although hemp plants can lodge, on the whole very tall hemp is remarkably resistant against wind.
Hemp has the ability to mitigate the toxin transfer from contaminated soil into food products. This process uses phytoremediation, an organic process where toxins are absorbed by plant roots and then stored in the cellulose for disposal. Hemp phytoremediation became more well-known after the Chernobyl disaster for its use in helping grow crops that are safe for consumption.
The exploding recreational market for marijuana has rapidly popularized many methods of consuming cannabis that was decidedly part of the fringe just a few short years ago. Smoking marijuana remains the most widely embraced method, due to the greater accessibility of marijuana flower. But legal recreational cannabis is introducing many marijuana users to new forms of the drug, especially concentrates and edibles. Here’s a brief overview of the major methods for consuming marijuana.
That being said, it was unlikely that the federal government was interested in pursuing individuals complying with state-mandated regulations surrounding legalized cannabis for recreational use, although the CSA law still gives them authority to do so. However, the new Trump administration may change this thinking and users of legal marijuana and legal dispensaries await further action and clarifying rules.

Right, the collection of the Vavilov Institute, St. Petersburg; of the 278 accessions for which chemical analyses were reported in Anonymous (1975), about 55% had THC levels >0.3%.
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.
Hemp allows farmers to build a livelihood from a crop that’s both good for the environment and the growers themselves. Hemp puts back nitrogen into the soil. Cotton, on the other hand, can deplete the land’s nutrients, especially if not rotated with other crops. Unlike cotton which produces shorter fibers, hemp, though brittle when dry, thrives when it’s wet, explains Derek Thomas, co-founder of Hemp Blue, a LA-based startup producing hemp-based jeans, jackets, and shirts. The long, wet fibers don’t break, but actually grow in strength, he says. Hemp’s longer, wet fibers have greater durability than cotton, which has short fibers that need to be spun and woven.

An observational study assessed the effectiveness of nabilone in advanced cancer patients who were experiencing pain and other symptoms (anorexia, depression, and anxiety). The researchers reported that patients who used nabilone experienced improved management of pain, nausea, anxiety, and distress when compared with untreated patients. Nabilone was also associated with a decreased use of opioids, nonsteroidal anti-inflammatory drugs, tricyclic antidepressants, gabapentin, dexamethasone, metoclopramide, and ondansetron.[56]
In December 2013, Uruguay became the first country to legalize growing, sale and use of cannabis.[219] After a long delay in implementing the retail component of the law, in 2017 sixteen pharmacies were authorized to sell cannabis commercially.[220] On June 19, 2018, the Canadian Senate passed a bill and the Prime Minister announced the effective legalization date as October 17, 2018.[37][221] Canada is the second nation to legalize the drug.[222]

Hemp is used to make a variety of commercial and industrial products including rope, textiles, clothing, shoes, food, paper, bioplastics, insulation, and biofuel.[5] The bast fibers can be used to make textiles that are 100% hemp, but they are commonly blended with other fibers, such as flax, cotton or silk, as well as virgin and recycled polyester, to make woven fabrics for apparel and furnishings. The inner two fibers of the plant are more woody and typically have industrial applications, such as mulch, animal bedding and litter. When oxidized (often erroneously referred to as "drying"), hemp oil from the seeds becomes solid and can be used in the manufacture of oil-based paints, in creams as a moisturizing agent, for cooking, and in plastics. Hemp seeds have been used in bird feed mix as well.[13] A survey in 2003 showed that more than 95% of hemp seed sold in the European Union was used in animal and bird feed.[14]
