“Specialty pulp” is the most important component of the hemp industry of the EU, and is expected to remain its core market for the foreseeable future. The most important specialty pulp products made from hemp are cigarette paper (Fig. 16), bank notes, technical filters, and hygiene products. Other uses include art papers and tea bags. Several of these applications take advantage of hemp’s high tear and wet strength. This is considered to be a highly stable, high-priced niche market in Europe, where hemp has an 87% market share of the “specialty pulp” sector (Karus et al. 2000). In Europe, decortication/refining machines are available that can produce 10 t/hour of hemp fiber suitable for such pulp use. North American capacity for hemp pulp production and value-added processing is much more limited than that of Europe, and this industry is negligible in North America.
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 A newer version of the break, which Lewis is currently working on, will have a capacity to produce about 2000lbs per day of raw material.
Dr. Ethan Russo, medical director at Phytecs, a biotechnology company spearheading research into plant- based medicines and the endocannabinoid system, took issue with Titus’s claim, however. “Bioaccumulators can recruit heavy metals from the soil,” Russo said, “but breaking them down would be alchemy.” Government regulation of the pharmaceutical industry is designed to protect consumers from unfounded scientific claims.

A population-based case-control study of 611 lung cancer patients revealed that chronic low Cannabis exposure was not associated with an increased risk of lung cancer or other upper aerodigestive tract cancers and found no positive associations with any cancer type (oral, pharyngeal, laryngeal, lung, or esophagus) when adjusting for several confounders, including cigarette smoking.[7]
A panellized system of hemp-lime panels for use in building construction is currently under test in a European Union-funded research collaboration led by the University of Bath. The panels are being designed to assure high-quality construction, rapid on-site erection, optimal hygrothermal performance from day one, and energy- and resource-efficient buildings. The 36-month-long work programme aims to refine product and manufacturing protocols, produce data for certification and marketing, warranty, insurance cover, and availability of finance. It also includes the development of markets in Britain, France, and Spain.[32]
Medical cannabis (or medical marijuana) refers to the use of cannabis and its constituent cannabinoids, to treat disease or improve symptoms. Cannabis is used to reduce nausea and vomiting during chemotherapy, to improve appetite in people with HIV/AIDS, and to treat chronic pain and muscle spasms.[102][103] Cannabinoids are under preliminary research for their potential to affect stroke.[104]

The high lipid-solubility of cannabinoids results in their persisting in the body for long periods of time.[131] Even after a single administration of THC, detectable levels of THC can be found in the body for weeks or longer (depending on the amount administered and the sensitivity of the assessment method).[131] A number of investigators have suggested that this is an important factor in marijuana's effects, perhaps because cannabinoids may accumulate in the body, particularly in the lipid membranes of neurons.[132]

Hemp, the non-psychoactive variety of the cannabis sativa plant, is already being integrated into several mature markets such as food, textiles, construction, personal care and nutraceuticals. This relatively quiet cannabis relative is emerging as a potential commodity ripe to not only impact, but possibly revolutionize, tech-driven markets and economies around the world.
In the United States, the legality of medical marijuana varies in substantial ways from state to state. There are currently 29 US states with legal medical cannabis laws, as well as the District of Columbia. That leaves 21 states where medical marijuana is entirely prohibited. Marijuana cultivation, possession, and use in any form is illegal at the federal level.
To this point, CBD oil has existed in a kind of liminal space— at once an illegal drug, a legal medication, and some kind of “dietary” supplement. It’s possible this could change in the coming years, however. GW Pharmaceuticals, a U.K.-based firm, has developed a “pure CBD” medication called Epidiolex that has shown promising test results. It is currently on a fast-track to receive FDA clearance. For some patients, Epidiolex could be a miracle cure. This summer, in Wired magazine, writer Fred Vogelstein chronicled his family’s own struggles to find an effective treatment for his son’s epilepsy—including experiments with hemp oil— and the immense hurdles they overcame to gain access to Epidiolex prior to its FDA approval. The drug could be for sale on pharmacy shelves in the near future, though exactly how near is hard to say.
Cannabis can be prepared into various foods generally called ‘edibles’. It takes between 1-3 hours to feel the effects after eating cannabis.2 Impatient or naïve users may believe they have not taken enough to feel the effects, and if they consume more they may find later that the psychoactive effects are unpleasantly strong. When edible products have inconsistent levels of THC even experienced users may find it difficult to regulate the amount consumed.
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.
Some of the research focuses that were explored in 2018 were: comparison of various agronomic factors on industrial hemp (planting dates, tillage regimens, range of soil fertility, etc.); hemp variety comparison for suitability to PA growing conditions; study of the effectiveness of potential herbicide products; comparison of hemp’s capability for weed suppression to other crops; surveying hemp crops for presence of arthropod and disease pests; evaluation of hemp’s performance for phytoremediation and land reclamation; study of hemp seed oil processing and marketability; development of industrial hemp products (using grain, stalks and flowers); genetic selection for desired hemp variety characteristics; and evaluations of hemp as an animal feed ingredient (cattle).  
The etymology is uncertain but there appears to be no common Proto-Indo-European source for the various forms of the word; the Greek term kánnabis is the oldest attested form, which may have been borrowed from an earlier Scythian or Thracian word.[9][10] Then it appears to have been borrowed into Latin, and separately into Slavic and from there into Baltic, Finnish, and Germanic languages.[11] Following Grimm's law, the "k" would have changed to "h" with the first Germanic sound shift,[9][12] after which it may have been adapted into the Old English form, hænep. However, this theory assumes that hemp was not widely spread among different societies until after it was already being used as a psychoactive drug, which Adams and Mallory (1997) believe to be unlikely based on archaeological evidence.[9] Barber (1991) however, argued that the spread of the name "kannabis" was due to its historically more recent drug use, starting from the south, around Iran, whereas non-THC varieties of hemp are older and prehistoric.[11] Another possible source of origin is Assyrian qunnabu, which was the name for a source of oil, fiber, and medicine in the 1st millennium BC.[11]
