Approximately 65% of sub-Saharan Africa’s agricultural land is degraded, according to data collected in 2015, resulting in food insecurity and a declining economy in a region where the agricultural industry employs more than half of the total labor force. Hemp’s soil nutrient replenishing properties could be the key to reviving crop production, providing a novel food source (hemp seeds) and boosting the agro-based economies of South Africa and other hemp-cultivating sub-Saharan countries.
There’s also been a lot of talk lately about “microdosing” CBD. This refers to an incremental process of finding your minimum effective dose. You can do this with any concentration of CBD oil, but lower concentrations will take longer. In a 2017 article in Rolling Stone, Dr. Dustan Sulak outlines his protocol for microdosing. You can begin this process by asking yourself three questions:
A Cochrane meta-analysis of 23 randomized RCTs reviewed studies conducted between 1975 and 1991 that investigated dronabinol or nabilone, either as monotherapy or as an adjunct to the conventional dopamine antagonists that were the standard antiemetics at that time. The chemotherapy regimens involved drugs with low, moderate, or high emetic potential. The meta-analysis graded the quality of evidence as low for most outcomes. The review concluded that individuals were more likely to report complete absence of N/V when they received cannabinoids compared with placebo, although they were more likely to withdraw from the study because of an adverse event. Individuals reported a higher preference for cannabinoids than placebo or prochlorperazine. There was no difference in the antiemetic effect of cannabinoids when compared with prochlorperazine. The authors concluded that Cannabis-based medications may be useful for treating refractory chemotherapy-induced N/V; however, they cautioned that their assessment may change with the availability of newer antiemetic regimens.
Cannabis is by far the most widely cultivated, trafficked and abused illicit drug. Half of all drug seizures worldwide are cannabis seizures. The geographical spread of those seizures is also global, covering practically every country of the world. About 147 million people, 2.5% of the world population, consume cannabis (annual prevalence) compared with 0.2% consuming cocaine and 0.2% consuming opiates. In the present decade, cannabis abuse has grown more rapidly than cocaine and opiate abuse. The most rapid growth in cannabis abuse since the 1960s has been in developed countries in North America, Western Europe and Australia. Cannabis has become more closely linked to youth culture and the age of initiation is usually lower than for other drugs. An analysis of cannabis markets shows that low prices coincide with high levels of abuse, and vice versa. Cannabis appears to be price-inelastic in the short term, but fairly elastic over the longer term. Though the number of cannabis consumers is greater than opiate and cocaine consumers, the lower prices of cannabis mean that, in economic terms, the cannabis market is much smaller than the opiate or cocaine market.
"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."
From 1982 to 2002 the EU provided the equivalent of about 50 million dollars to develop new flax and hemp harvesting and fiber processing technologies (Karus et al. 2000). Because of the similarities of flax and hemp, the technologies developed for one usually are adaptable to the other. In addition, various European nations and private firms contributed to the development of hemp technologies. Accordingly, Europe is far more advanced in hemp development with respect to all fiber-based applications than other parts of the world. The EU currently dedicates about 30,000 ha to hemp production. France is the leading country in hemp cultivation in the EU, and 95% of the non-seed production is used for “specialty pulp” as described below. Harvesting and processing machinery for fiber hemp is highly advanced in Europe, and some has been imported into Canada. However, there is insufficient fiber processing capacity to handle hemp produced in Canada.
Although global abnormalities in white matter and grey matter are not associated with cannabis abuse, reduced hippocampal volume is consistently found. Amygdalar abnormalities are sometimes reported, although findings are inconsistent. Preliminary evidence suggests that this effect is largely mediated by THC, and that CBD may even have a protective effect.
C.S. Lewis said “badness is only spoiled goodness.” This may be an apt quote regarding public perception. It’s true that hemp’s scientific name is the same as that other Cannabis sativa, marijuana, but its constituents are different. The three cannabis plants have three different species: Sativa, used for industrial fibers, oils, food, drugs and medicine; Indica, to induce sleep; and Ruderalis, for food production. Hemp seeds contain high amounts of essential fatty acids – more than any fish and most fish oil supplements. The oil has linoleic acid, alpha-linolenic acid, and at least 20 amino acids. Altogether, hemp supplies innumerable health benefits. After decades of misunderstanding, scientists have again been tapping the amazing potential of this versatile plant.
You then take your first drop of CBD oil, wait 45 minutes, then ask the questions again. If you feel no different and there’s no change in the way you answer those questions, you increase the dose by small increments until you do notice a difference. You can continue this process over several days – and at some point, you’ll find that taking more doesn’t change your scores. That is your minimum effective dose.
Preliminary research indicates that cannabidiol may reduce adverse effects of THC, particularly those causing intoxication and sedation, but only at high doses. Safety studies of cannabidiol showed it is well-tolerated, but may cause tiredness, diarrhea, or changes in appetite as common adverse effects. Epidiolex documentation lists sleepiness, insomnia and poor quality sleep, decreased appetite, diarrhea, and fatigue.
According to researchers, 25 percent of all cancer patients use medical marijuana. Cancer patients are finding relief from medical cannabis. And they want to know more about it. Research conducted at St. George’s University of London, found the two most common cannabinoids in marijuana, tetrahydrocannabinol (THC) and cannabidiol (CBD), weakened the ferocity of cancer cells and made them more susceptible to radiation treatment. Other studies have shown that medical marijuana treatments can slow the growth of cancer cells and halt their spread to other parts of the body.

One of the reasons hemp fiber has been valued is because of its length. The primary bast fibers in the bark are 5–40 mm long, and are amalgamated in fiber bundles which can be 1–5 m long (secondary bast fibers are about 2 mm long). The woody core fibers are short—about 0.55 mm—and like hardwood fibers are cemented together with considerable lignin. The core fibers are generally considered too short for high grade paper applications (a length of 3 mm is considered ideal), and too much lignin is present. While the long bast fibers have been used to make paper almost for 2 millennia, the woody core fibers have rarely been so used. Nevertheless it has been suggested that the core fibers could be used for paper making, providing appropriate technology was developed (de Groot et al. 1998). In any event, the core fibers, have found a variety of uses, as detailed below. The long, lignin-poor bast fibers also have considerable potential to be used in many non-paper, non-textile applications, as noted below.
Cannabis has an ancient history of ritual use and is found in pharmacological cults around the world. Hemp seeds discovered by archaeologists at Pazyryk suggest early ceremonial practices like eating by the Scythians occurred during the 5th to 2nd century BC, confirming previous historical reports by Herodotus. It was used by Muslims in various Sufi orders as early as the Mamluk period, for example by the Qalandars. Smoking pipes uncovered in Ethiopia and carbon-dated to around c. AD 1320 were found to have traces of cannabis.
In Europe and Asia, hemp farming has been conducted for millennia. Although most countries ceased growing hemp after the second word war, some didn’t, including France, China, Russia, and Hungary, so that essential knowledge of how to grow and process hemp was maintained. When commercial hemp cultivation resumed in Canada in 1997, many farmers undertook to grow the crop without appreciating its suitability for their situation, or for the hazards of an undeveloped market. Hemp was often grown on farms with marginal incomes in the hopes that it was a savior from a downward financial spiral. The myth that hemp is a wonder crop that can be grown on any soil led some to cultivate on soils with a history of producing poor crops; of course, a poor crop was the result.
So-called “pure hybrids,” while oxymoronic in name, indicate marijuana strains that are believed to offer a perfect blend or balance of sativa’s energizing and indica’s sedating effects. Other hybrid strains of cannabis tend to place the emphasis on one end of the spectrum or the other. These are called “sativa-dominant” or “indica-dominant,” accordingly.
There is great variation in Cannabis sativa, because of disruptive domestication for fiber, oilseed, and narcotic resin, and there are features that tend to distinguish these three cultigens (cultivated phases) from each other. Moreover, density of cultivation is used to accentuate certain architectural features. Figure 5 illustrates the divergent appearances of the basic agronomic categories of Cannabis in typical field configurations.
The challenge to find lighter and longer-lasting energy storage devices (e.g., batteries) can be found in almost every sector. Hemp could prove to revolutionize battery life by aiding in the development of faster, smaller and cheaper supercapacitors. A supercapacitor is an energy storage device that can discharge powerful infusions of energy, needed only in small bursts. Such powerful discharges are used in braking systems of electric vehicles, the powering on of computers and new technologies such as rapid phone charging or cordless tools.

Beckerman also urged supporters of hemp (and of its danker cousin) to be more vigilant than ever about federal and state-level law and policy moves going forward. “Special interests and residual hysteria will continue to try to get in there, to stomp on the little guy, and on consumer rights and safety, and to over-regulate, so it’s more important than ever that we organize and engage,” she said.
Because C. sativa has been a neglected crop for so long in North America, there are only negligible genetic resources available on this continent. Most germplasm stocks of hemp are in Europe, and the largest and most important collection is the Vavilov Institute gene bank in Leningrad. Figure 11 shows THC concentrations in the Vavilov collection, as well as in our own collection, largely of European germplasm. A disturbingly high percentage of the collections have THC levels higher than 0.3%, making it difficult to incorporate these into breeding programs.
Senate Majority Leader Mitch McConnell (R-KY) introduced new legislation in April that would declassify non-psychoactive cannabis varieties -- more commonly referred to as hemp -- from the Controlled Substances Act. The legislative proposal comes as part of McConnell's Hemp Farming Act of 2018, which would remove barriers placed on banking access and water rights in addition to legalizing the crop.
On July 4, a petition will be delivered to Congress urging them to pass the Industrial Hemp Farming Act of 2015/2016 (S.134 and H.R. 525), legalizing the cultivation of industrial hemp in the US. Although Betsy Ross sewed the first American flag with hemp fibers and George Washington grew hemp at Mount Vernon, the fibrous plant, often confused with marijuana, became illegal during the Prohibition era, as politicians tried to regulate pharmaceuticals.
With a hypothesis that chronic marijuana use produces adverse effects on the human endocrine and reproductive systems, the association between Cannabis use and incidence of testicular germ cell tumors (TGCTs) has been examined.[12-14] Three population-based case-control studies reported an association between Cannabis use and elevated risk of TGCTs, especially nonseminoma or mixed-histology tumors.[12-14] However, the sample sizes in these studies were inadequate to address Cannabis dose by addressing associations with respect to recency, frequency, and duration of use. In a study of 49,343 Swedish men aged 19 to 21 years enrolled in the military between 1969 and 1970, participants were asked once at the time of conscription about their use of Cannabis and were followed up for 42 years. This study found no evidence of a significant relation between “ever” Cannabis use and the development of testicular cancer, but did find that “heavy” Cannabis use (more than 50 times in a lifetime) was associated with a 2.5-fold increased risk. Limitations of the study were that it relied on indirect assessment of Cannabis use; and no information was collected on Cannabis use after the conscription-assessment period or on whether the testicular cancers were seminoma or nonseminoma subtypes. These reports established the need for larger, well-powered, prospective studies, especially studies evaluating the role of endocannabinoid signaling and cannabinoid receptors in TGCTs.
The following sketch of hemp cultivation is insufficient to address all of the practical problems that are encountered by hemp growers. Bócsa and Karus (1998) is the best overall presentation of hemp growing available in English. The reader is warned that this book, as well as almost all of the literature on hemp, is very much more concerned with fiber production than oilseed production. McPartland et al. (2000) is the best presentation available on diseases and pests, which fortunately under most circumstances do limited damage. The resource list presented below should be consulted by those wishing to learn about hemp production. Provincial agronomists in Canada now have experience with hemp, and can make local recommendations. Particularly good web documents are: for Ontario (OMAFRA Hemp Series, several documents): www.gov.on.ca/OMAFRA/english/crops/hort/hemp.html); for Manitoba (several documents): www.gov.mb.ca/agriculture/crops/hemp/bko01s00.html; for British Columbia: (BC Ministry of Agriculture and Foods Fact Sheet on Industrial Hemp, prepared by A. Oliver and H. Joynt): www.agf.gov.bc.ca/croplive/plant/horticult/specialty/specialty.htm
Specific city and county laws have been enacted to regulate how citizens and tourists may possess and consume marijuana. Penalties exist for driving while under the influence of marijuana. Someone driving under the influence of marijuana is considered impaired in both Colorado and Washington when five nanograms per milliliter (ng/mL) of blood or more of active THC is detected.
France is Europe's biggest producer (and the world's second largest producer) with 8,000 hectares cultivated. 70-80% of the hemp fibre produced in 2003 was used for specialty pulp for cigarette papers and technical applications. About 15% was used in the automotive sector, and 5-6% was used for insulation mats. About 95% of hurds were used as animal bedding, while almost 5% was used in the building sector. In 2010/2011, a total of 11,000 hectares (27,000 acres) was cultivated with hemp in the EU, a decline compared with previous year.
Kent, My mother has suffered from severe migraines since she was a child. Six weeks ago, she received the hemp oil tincture (I do not know what dosage). She does not take it daily. She rubs a drop or two on her temples at the start of a migraine. The drops worked more effectively for her than her medication did, and now that is all she uses. Hope this helps.
“Hemp is of high nutritional quality because it contains high amounts of unsaturated fatty acids… Linoleic acid and alpha-linolenic acid are the only two fatty acids that must be ingested and are considered essential to human health … In contrast to shorter-chain and more saturated fatty acids, these essential fatty acids do not serve as energy sources, but as raw materials for cell structure and as precursors for biosynthesis for many of the body’s regulatory biochemicals…”
The United Kingdom and Germany resumed commercial production in the 1990s. British production is mostly used as bedding for horses; other uses are under development. Companies in Canada, the UK, the United States, and Germany, among many others, process hemp seed into a growing range of food products and cosmetics; many traditional growing countries still continue to produce textile-grade fibre.
In Japan, hemp was historically used as paper and a fiber crop. There is archaeological evidence cannabis was used for clothing and the seeds were eaten in Japan back to the Jōmon period (10,000 to 300 BC). Many Kimono designs portray hemp, or asa (Japanese: 麻), as a beautiful plant. In 1948, marijuana was restricted as a narcotic drug. The ban on marijuana imposed by the United States authorities was alien to Japanese culture, as the drug had never been widely used in Japan before. Though these laws against marijuana are some of the world's strictest, allowing five years imprisonment for possession of the drug, they exempt hemp growers, whose crop is used to make robes for Buddhist monks and loincloths for Sumo wrestlers. Because marijuana use in Japan has doubled in the past decade, these exemptions have recently been called into question.
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.
In the 1970s, the taxonomic classification of Cannabis took on added significance in North America. Laws prohibiting Cannabis in the United States and Canada specifically named products of C. sativa as prohibited materials. Enterprising attorneys for the defense in a few drug busts argued that the seized Cannabis material may not have been C. sativa, and was therefore not prohibited by law. Attorneys on both sides recruited botanists to provide expert testimony. Among those testifying for the prosecution was Dr. Ernest Small, while Dr. Richard E. Schultes and others testified for the defense. The botanists engaged in heated debate (outside of court), and both camps impugned the other's integrity. The defense attorneys were not often successful in winning their case, because the intent of the law was clear.
Support for legalization has steadily grown over the last several years. Today, medical marijuana is legal in 23 states and the District of Columbia. And even federal officials have begun to soften their stances. Last fall, outgoing Attorney General Eric Holder signaled his support for removing marijuana from the list of Schedule I narcotics. “I think it’s certainly a question we need to ask ourselves, whether or not marijuana is as serious of a drug as heroin,” Holder said. This summer, Chuck Rosenberg, the acting administrator of the U.S. Drug Enforcement Administration, acknowledged that marijuana is not as dangerous as other Schedule I drugs and announced his agents would not be prioritizing marijuana enforcement. Still, as long as marijuana remains illegal under federal law, the haphazard system in which it is studied, produced, and distributed will remain, and Americans will not be able to take full advantage of its medicinal properties.
Unlike other Cannabis sativa varieties and hybrids, which are mostly grown for their chemically potent flowers (or 'buds'), hemp is also legally distinguished from marijuana in the US as containing less than 0.3% of the cannabinoid chemical THC — considered to be the most intoxicating, psychoactive component in cannabis plants, as well as a treatment option for certain serious illnesses.
Neuropathic pain is a symptom cancer patients may experience, especially if treated with platinum-based chemotherapy or taxanes. Two RCTs of inhaled Cannabis in patients with peripheral neuropathy or neuropathic pain of various etiologies found that pain was reduced in patients who received inhaled Cannabis, compared with those who received placebo.[58,59] Two additional trials of inhaled Cannabis have also demonstrated the benefit of Cannabis over placebo in HIV-associated neuropathic pain.[60,61]
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)
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.
The U.S. hemp-derived CBD market alone is projected to reach $450 million by 2020, and China's cannabis market could grow to 100 billion yuan by 2022 (approximately $14.5 billion). Hemp is already interwoven into the futures of the automotive, construction, energy, environmental mediation and technology industries. Once fully utilized and legal, this plant could impact the global economic positionings of North America, China and Africa.
Following an 1836–1840 travel in North Africa and the Middle East, French physician Jacques-Joseph Moreau wrote on the psychological effects of cannabis use; Moreau was a member of Paris' Club des Hashischins (founded in 1844). In 1842, Irish physician William Brooke O'Shaughnessy, who had studied the drug while working as a medical officer in Bengal with the East India company, brought a quantity of cannabis with him on his return to Britain, provoking renewed interest in the West. Examples of classic literature of the period featuring cannabis include Les paradis artificiels (1860) by Charles Baudelaire and The Hasheesh Eater (1857) by Fitz Hugh Ludlow.
Market considerations also heavily determine the wisdom of investing in hemp. Growing hemp unfortunately has a magnetic attraction to many, so there is danger of overproduction. A marketing board could be useful to prevent unrestrained competition and price fluctuations, but is difficult to establish when the industry is still very small. As noted above, unwise investment in Canada produced a glut of seeds that resulted in price dumping and unprofitable levels for the majority. Cultural and production costs of hemp have been said to be comparable to those for corn, and while the truth of this remains to be confirmed, the legislative burden that accompanies hemp puts the crop at a unique disadvantage. Among the problems that Canadian farmers have faced are the challenge of government licensing (some delays, and a large learning curve), very expensive and sometime poor seed (farmers are not allowed to generate their own seed), teenagers raiding fields in the mistaken belief that marijuana is being grown, and great difficulties in exportation because of the necessity of convincing authorities that hemp is not a narcotic. Unless the producer participates in sharing of value-added income, large profits are unlikely. The industry widely recognizes that value added to the crop is the chief potential source of profit, as indeed for most other crops.
Cannabis has held sacred status in several religions. It has been used in an entheogenic context – a chemical substance used in a religious, shamanic, or spiritual context - in the Indian subcontinent since the Vedic period dating back to approximately 1500 BCE, but perhaps as far back as 2000 BCE. There are several references in Greek mythology to a powerful drug that eliminated anguish and sorrow. Herodotus wrote about early ceremonial practices by the Scythians, thought to have occurred from the 5th to 2nd century BCE. In modern culture the spiritual use of cannabis has been spread by the disciples of the Rastafari movement who use cannabis as a sacrament and as an aid to meditation. The earliest known reports regarding the sacred status of cannabis in the Indian subcontinent come from the Atharva Veda estimated to have been written sometime around 2000–1400 BCE.
The US Drug Enforcement Administration’s online criminal justice statistics for 2000 (cscmosaic.albany.edu/sourcebook/1995/pdf/t440.pdf) shows the following seizures and eradication of plants of C. sativa: 40,929 outdoor plots (2,597,796 plants), 139,580,728 ditchweed (ruderal plants), 2,361 indoor operations (217,105 plants), for a grand total of 2,814, 903 plants destroyed. Impressively, the species was grown in all 50 states (including outdoor seizures in every state except Wyoming)! It is of course impossible to know exactly how much marijuana is cultivated in the United States, and perhaps only 10% to 20% of the amount grown is seized. The profitability of the illegal crop is indicated by a comparison of the cost of a bushel of corn (roughly $2.50) and a bushel of manicured marijuana (about $70,000; it has been suggested that prices range from $500 a pound, for low-quality marijuana, to more than $5,000 a pound for “boutique” strains like “Northern Lights” and “Afghan Kush”). According to a National Organization for the Reform of Marijuana Laws (NORML) (mir.drugtext.org/marijuananews/marijuana_ranks_fourth_largest_c.htm) marijuana is at least the fourth most valuable crop in America, outranked only by corn, soybeans, and hay. It was estimated that 8.7 million marijuana plants were harvested in 1997, worth $15.1 billion to growers and $25.2 billion on the retail market (the wholesale value was used to compare marijuana to other cash crops). Marijuana was judged to be the largest revenue producing crop in Alabama, California, Colorado, Hawaii, Kentucky, Maine, Rhode Island, Tennessee, Virginia, and West Virginia, and one of the top five cash crops in 29 other states.
Cannabis plants can be male, female, or hermaphrodite. The dried marijuana flowers that humans consume, however, come from the female plant. That’s because female plants produce large resin-secreting flowers that are rich in cannabinoids and free of seeds. Hence, female plants are the ones growers prefer, though of course, male marijuana plants are a requirement for pollination.
As noted above, hemp seed cake makes an excellent feed for animals. However, feeding entire plants is another matter, because the leaves are covered with the resin-producing glands. While deer, groundhogs, rabbits, and other mammals will nibble on hemp plants, mammals generally do not choose to eat hemp. Jain and Arora (1988) fed narcotic Cannabis refuse to cattle, and found that the animals “suffered variable degrees of depression and revealed incoordination in movement.” By contrast, Letniak et al. (2000) conducted an experimental trial of hemp as silage. No significant differences were found between yield of the hemp and of barley/oat silage fed to heifers, suggesting that fermenting hemp plants reduces possible harmful constituents.
Hemp is the fiber and seed part of the Cannabis Sativa L. plant, opposed to the flower part of the plant which is “legally considered” marijuana. The fiber and seeds are incredible valuable and is why hemp is often called a “cash crop”. Hemp is a very hearty plant and grows very quickly in very diverse soil conditions. Cultivation of hemp for industrial purposes has been done by many civilizations for over 12,000 years. Industrial hemp was the desired fiber used to manufacture rope, canvas, paper, and clothing until alternative textiles and synthetics for these purposes were discovered. Although China has been the largest hemp producer over the years, other countries such as Australia and Canada are catching up. It has been illegal for anyone to grow hemp in the United States as hemp is illegal under the marijuana prohibition act but Colorado has changed the laws and paved the way for industrial hemp production again in the United States(see hemp history). Now hemp oils, hemp plastics, hemp building materials and many hemp fiber products can be seen and purchased on the market. Hemp is truly an amazing plant with the potential to help “green up” many industries.
The woody core (hurds, sometimes called shives) of hemp makes remarkably good animal bedding (Fig. 28, 29). The hurds are sometimes molded into small pellets for bedding applications (Fig. 30). Such appears to be unsurpassed for horse bedding, and also make an excellent litter for cats and other pets (Fig. 31). The hurds can absorb up to five times their weight in moisture (typically 50% higher than wood shavings), do not produce dust (following initial dust removal), and are easily composted. Hemp bedding is especially suited to horses allergic to straw. In Europe, the animal bedding market is not considered important (Karus et al. 2000), but in North America there are insufficient hemp hurds available to meet market demand.
Industrial hemp is a versatile agricultural plant which could one day be a valuable crop option for Pennsylvania farmers. The Commonwealth of Pennsylvania has taken some important steps toward making that a reality. Following Governor Wolf’s signing of the Industrial Hemp Research Act, Number 92 in 2016, the Pennsylvania Department of Agriculture’s Industrial Hemp Research Pilot Program started issuing permits for research & growth of industrial hemp in 2017. Pennsylvania’s industrial hemp legislation was sparked by the passage of the 2014 Farm Bill, which gave federal permission for institutions of higher education or state Departments of Agriculture to research the cultivation and marketing of industrial hemp. As part of Pennsylvania’s Research Pilot Program, industrial hemp was legally grown in the Commonwealth after an 80 years hiatus. The Department of Agriculture has issued 35 research permits in the last two years to institutions of higher education and to farmers, business or individuals in contract with the Department to participate in the research of industrial hemp cultivation and marketing in Pennsylvania. In 2018, 35 research permits were issued to researchers, who cultivated industrial hemp in 25 Pennsylvania counties.
Hashish (also spelled hasheesh, hashisha, or simply hash) is a concentrated resin cake or ball produced from pressed kief, the detached trichomes and fine material that falls off cannabis flowers and leaves. or from scraping the resin from the surface of the plants and rolling it into balls. It varies in color from black to golden brown depending upon purity and variety of cultivar it was obtained from. It can be consumed orally or smoked, and is also vaporised, or 'vaped'. The term "rosin hash" refers to a high quality solventless product obtained through heat and pressure.

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.
