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).
Cannabinoids are a class of compounds that interact with receptors throughout your body. CBD is just one of dozens of cannabinoids found in cannabis, including tetrahydrocannabinol (THC), which is the one responsible for marijuana’s famous high. Medical cannabis is technically any cannabis product used for medicinal purposes, and these can contain THC or CBD or both, said Nick Jikomes, a neuroscientist at Leafly, a website that provides information about legal cannabis. “A common mistake people make is to think that CBD is ‘the medical cannabinoid’ and THC is ‘the recreational cannabinoid.’” That’s inaccurate, he said, because THC is a potent anti-inflammatory and can be helpful for pain.

This is a huge, HUGE step for N.C. First of all farmers can FINALLY make money off land that has grown tobacco for generations. FINALLY doubter I finding out there are many uses for the plant. Perhaps one of the biggest things is the impact on the environment. Most products, if not all, are biodegradable. Also, a huge factor is that in the field of medicine. Will this lead to medical and/or recreational marijuana? Time will tell. As for me, I quit smoking it 20 years ago. I do, however, believe any and all forms of cannabis should and will be made legal. Legal, if for no other reason, so we can stop making people who smoke it into criminals, filling up our jails and prisons. This will free up police, etc.. to finding real criminals. Last, but defiantly not least, IMHO, there is the N.C. aspect. That being I thought we would never, EVER see this time in N.C. Even if it is just industrial hemp for now, it’s a start. Who knows, in the not too distant future, legislatures and law enforcement will become open minded enough to legalize all forms of cannabis, HOPEFULLY. With the youth of these times moving into the right fields, and of course us boomers weighing in, it won’t be too long. AMEN
The Gateway Hypothesis states that cannabis use increases the probability of trying "harder" drugs. The hypothesis has been hotly debated as it is regarded by some as the primary rationale for the United States prohibition on cannabis use. A Pew Research Center poll found that political opposition to marijuana use was significantly associated with concerns about health effects and whether legalization would increase marijuana use by children.
In December 2012, the U.S. state of Washington became the first state to officially legalize cannabis in a state law (Washington Initiative 502) (but still illegal by federal law), with the state of Colorado following close behind (Colorado Amendment 64). On January 1, 2013, the first marijuana "club" for private marijuana smoking (no buying or selling, however) was allowed for the first time in Colorado. The California Supreme Court decided in May 2013 that local governments can ban medical marijuana dispensaries despite a state law in California that permits the use of cannabis for medical purposes. At least 180 cities across California have enacted bans in recent years.
TINA.org reached out to the Zwagils, the company’s founders, for comment. Erin McGinnis, HempWorx’s director of compliance, responded with a statement indicating the company is in the process of reviewing every item in the above article and every entry in the health and income claims databases TINA.org compiled. As of 9/6/18, HempWorx had removed 83 of more than 100 health claims and 35 of more than 50 income claims. In addition, McGinnis said HempWorx has suspended several distributors and terminated one in response to TINA.org’s findings.
A study by Henquet and colleagues (2004) substantially replicated both the Swedish and Dutch studies in a 4-year follow-up of a cohort of 2437 adolescents and young adults between 1995 and 1999 in Munich. They found a dose–response relationship between self-reported cannabis use at baseline and the likelihood of reporting psychotic symptoms. As in the Dutch cohort, young people who reported psychotic symptoms at baseline were much more likely to experience psychotic symptoms at follow-up if they used cannabis than were cannabis-using peers without such a history.
As part of the Agriculture Improvement Act of 2018, or the 2018 Farm Bill, signed by Republican President Donald Trump, the Hemp Farming Act of 2018 removed hemp (with less than 0.3% THC) from Schedule I, the most restrictive classification of controlled substances that are considered highly prone to abuse and not to have any medicinal benefit. This move allowed for cultivation and distribution of hemp as a legal agricultural product. Under the Hemp Farming Act, hemp cultivation is no longer limited to state departments and universities. In addition, the act allows hemp farmers rights to water, crop insurance, and federal agricultural grants, as well as legal access to national banking. Hemp may also be transported across state lines.
Consumers report using CBD for a huge variety of health and wellness reasons, but a lot more research is needed to determine which symptoms and ailments it works best for. Currently, there are more than 40 clinical trials enrolling patients to examine the effectiveness of CBD for a variety of diseases, including substance use disorder, chronic pain, post-traumatic stress disorder (PTSD), depression, schizophrenia, and many others. Most importantly, CBD is incredibly safe, and not addictive. Even young children can tolerate daily doses of up to twenty milligrams (20 mg) per kilogram (1 kg) of body weight (for a 175 pound adult, that’s more than 1,500 mg). The most common side effect of high-dose CBD is sleepiness.
Lisa Hamilton, a jeweler and doula in Brooklyn, NY, knows about the side effects. She recently tried CBD for the shoulder pain that plagued her five years after an accident. Her doctor certified that she was in chronic pain, which under New York State law allowed her to buy from a state dispensary. One Friday, she swallowed two 10-mg capsules, the amount recommended at the dispensary, then took another two on Saturday. “By Sunday, it felt like I’d gotten hit by a truck. Every muscle and joint ached,” Hamilton says. She cut back to one pill a day the following week, but still felt hungover. She stopped after that.
Although hemp and marijuana are both varieties of cannabis, there is a difference between them. The differences between these cannabis varieties are primarily evident in the way each plant is used. These differences are also documented in the language, laws, and regulations that apply to each variety. In this introduction to hemp, we’ll break down the anatomy, history, use, and legality of the hemp plant to get to the heart of not only what distinguishes it from marijuana, but also what makes it such a viable, versatile commodity.
The high lipid-solubility of cannabinoids results in their persisting in the body for long periods of time. 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). 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.
Cannabis plants produce a unique family of terpeno-phenolic compounds called cannabinoids, some of which produce the "high" which may be experienced from consuming marijuana. There are 483 identifiable chemical constituents known to exist in the cannabis plant, and at least 85 different cannabinoids have been isolated from the plant. The two cannabinoids usually produced in greatest abundance are cannabidiol (CBD) and/or Δ9-tetrahydrocannabinol (THC), but only THC is psychoactive. Since the early 1970s, Cannabis plants have been categorized by their chemical phenotype or "chemotype", based on the overall amount of THC produced, and on the ratio of THC to CBD. Although overall cannabinoid production is influenced by environmental factors, the THC/CBD ratio is genetically determined and remains fixed throughout the life of a plant. Non-drug plants produce relatively low levels of THC and high levels of CBD, while drug plants produce high levels of THC and low levels of CBD. When plants of these two chemotypes cross-pollinate, the plants in the first filial (F1) generation have an intermediate chemotype and produce intermedite amounts of CBD and THC. Female plants of this chemotype may produce enough THC to be utilized for drug production.
Cannabidiol and cannabidiolic acid work by binding to various receptor targets throughout the central nervous system and the rest of the body. Acting at these receptor sites, it exerts influence on the metabolism of various neurotransmitter systems. It seems like ‘snake oil’ that one compound can have all the beneficial effects listed above; however, cannabinoid receptors exist throughout the nervous system and it is known that such a ubiquitous receptor must be involved in nearly everything the nervous system does, just like serotonin and dopamine receptors. Dopamine affects pleasure, but also pain. Anxiety and also relaxation. Heart contraction and blood pressure. All of these systems are integrated so cannabinoid receptors will indeed have effects on all of these systems and exogenous cannabinoids from plants can definitely have therapeutic effects which are extensive.
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.

The genus Cannabis was formerly placed in the nettle (Urticaceae) or mulberry (Moraceae) family, and later, along with the genus Humulus (hops), in a separate family, the hemp family (Cannabaceae sensu stricto). Recent phylogenetic studies based on cpDNA restriction site analysis and gene sequencing strongly suggest that the Cannabaceae sensu stricto arose from within the former family Celtidaceae, and that the two families should be merged to form a single monophyletic family, the Cannabaceae sensu lato.
Cannabis most likely originates from Central Asia, as archeological evidence indicates that it was already cultivated in China for food and fiber 10 000 years ago. Even in ancient Egyptian mummies, clues have been found for the use of Cannabis as food or medicine.25 In fact, Cannabis is one of the oldest known medicinal plants and is described in almost every ancient handbook on plant medicine, most commonly in the form of a tincture or a tea.26,27 Some religions were closely related with the properties of the Cannabis plant. For example, in Hindu legend, Cannabis is believed to be the favorite food of the god Shiva, because of its energizing properties. As Cannabis spread from Asia toward the West, almost every culture came into contact with this miracle plant. Nowadays, varieties of Cannabis can be found in all temperate and tropical zones, except in humid, tropical rain forests.28
Hemp is grown in temperate zones as an annual cultivated from seed and can reach a height of up to 5 metres (16 feet). Crops grow best in sandy loam with good drainage and require average monthly rainfall of at least 65 mm (2.5 inches) throughout the growing season. Crops cultivated for fibre are densely sowed and produce plants averaging 2–3 metres (6–10 feet) tall with almost no branching. Plants grown for oilseed are planted farther apart and are shorter and many-branched. The slender stalks are hollow except at the tip and base. The leaves are compound with palmate shape, and the flowers are small and greenish yellow. Seed-producing flowers form elongate, spikelike clusters growing on the pistillate, or female, plants. Pollen-producing flowers form many-branched clusters on staminate, or male, plants. Maximum yield and quality are obtained by harvesting soon after the plants reach maturity, indicated by the full blossoms and freely shedding pollen of the male plants. Although sometimes pulled up by hand, plants are more often cut off about 2.5 cm (1 inch) above the ground.
