According to the United Nations Office on Drugs and Crime (UNODC), "the amount of THC present in a cannabis sample is generally used as a measure of cannabis potency."[149] The three main forms of cannabis products are the flower, resin (hashish), and oil (hash oil). The UNODC states that cannabis often contains 5% THC content, resin "can contain up to 20% THC content", and that "Cannabis oil may contain more than 60% THC content."[149]
An industrial hemp license issued by the state provides authorization for the production of industrial hemp at a particular growing area by a particular individual or entity. Licenses will expire on the last day of December of the year that they are issued. Renewals do not require new fingerprinting unless the department requests it or if the corporate officers have changed.
Cannabis drug preparations have been employed medicinally in folk medicine since antiquity, and were extensively used in western medicine between the middle of the 19th century and World War II, particularly as a substitute for opiates (Mikuriya 1969). A bottle of commercial medicinal extract is shown in Fig. 41. Medical use declined with the introduction of synthetic analgesics and sedatives, and there is very limited authorized medical use today, but considerable unauthorized use, including so-called “compassion clubs” dispensing marijuana to gravely ill people, which has led to a momentous societal and scientific debate regarding the wisdom of employing cannabis drugs medically, given the illicit status. There is anecdotal evidence that cannabis drugs are useful for: alleviating nausea, vomiting, and anorexia following radiation therapy and chemotherapy; as an appetite stimulant for AIDS patients; for relieving the tremors of multiple sclerosis and epilepsy; and for pain relief, glaucoma, asthma, and other ailments [see Mechoulam and Hanus (1997) for an authoritative medical review, and Pate (1995) for a guide to the medical literature]. To date, governmental authorities in the US, on the advice of medical experts, have consistently rejected the authorization of medical use of marijuana except in a handful of cases. However, in the UK medicinal marijuana is presently being produced sufficient to supply thousands of patients, and Canada recently authorized the cultivation of medicinal marijuana for compassionate dispensation, as well as for a renewed effort at medical evaluation.

CBD is a cannabinoid found in both cannabis and hemp. By using stringently controlled organic hemp – which only contains trace amounts of THC – we ensure that our lab here at Royal Queen Seeds can extract all of the CBD goodness, without any worry of THC contamination. RQS CBD Oil contains less than 0.2% THC, making impossible to get high with it, and legal in most EU countries.
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.
Cannabis is an annual, dioecious, flowering herb. The leaves are palmately compound or digitate, with serrate leaflets.[10] The first pair of leaves usually have a single leaflet, the number gradually increasing up to a maximum of about thirteen leaflets per leaf (usually seven or nine), depending on variety and growing conditions. At the top of a flowering plant, this number again diminishes to a single leaflet per leaf. The lower leaf pairs usually occur in an opposite leaf arrangement and the upper leaf pairs in an alternate arrangement on the main stem of a mature plant.
The word cannabis is from Greek κάνναβις (kánnabis) (see Latin cannabis),[134] which was originally Scythian or Thracian.[135] It is related to the Persian kanab, the English canvas and possibly even to the English hemp (Old English hænep).[135] In modern Hebrew, קַנַּבּוֹס‬ qannabōs (modern pronunciation: [kanaˈbos]) is used but there are those who have theorized that it was referred to in antiquity as קני בושם q'nei bosem, a component of the biblical anointing oil.[136][137] Old Akkadian qunnabtu, Neo-Assyrian and Neo-Babylonian qunnabu were used to refer to the plant meaning "a way to produce smoke".[138][139][140]
Earliest reference to euphoric use of C. sativa appears to date to China of 5 millennia ago, but it was in India over the last millennium that drug consumption became more firmly entrenched than anywhere else in the world. Not surprisingly, the most highly domesticated drug strains were selected in India. While C. sativa has been used as a euphoriant in India, the Near East, parts of Africa, and other Old World areas for thousands of years, such use simply did not develop in temperate countries where hemp was raised. The use of C. sativa as a recreational inebriant in sophisticated, largely urban settings is substantially a 20th century phenomenon.
In late 2017, researchers with the University of Guelph in Canada published the first-ever study to document the ideal growing conditions for cannabis. Using liquid organic fertilizer with a PKN ratio of 1.3P–1.7K-4.0N, the experiment tested five increasing rates of fertilization. They also tested two coir-based soil-less growing media, or “substrates.”
38 states and Puerto Rico considered legislation related to industrial hemp in 2017. These bills ranged from clarifying existing laws to establishing new licensing requirements and programs.  At least 15 states enacted legislation in 2017 — Arkansas, Colorado, Florida, Hawaii, North Dakota, Nevada, New York, Oregon, South Carolina, Tennessee, Virginia, Washington, West Virginia, Wisconsin and Wyoming. Florida, Wisconsin and Nevada authorized new research or pilot programs. The governors of Arizona and New Mexico vetoed legislation, which would have established new research programs. 
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.

No medication seemed to provide a great deal of relief for Harper’s symptoms. But in 2013, three years after their trip to Boston, Penny and Dustin caught an installment of CNN’s medical marijuana documentary and began researching what they could obtain in Texas, where medical marijuana is illegal. Their internet searches soon led them to HempMedsPx and Real Scientific Hemp Oil. The company sent Penny a vial of hemp oil, which she administered to Harper that September.


Hemp oil has never been as popular as other marijuana products. With little to no THC, CBD-rich strains of cannabis don’t deliver the pleasant buzz recreational users seek out in marijuana. In the 1970s, however, scientists found that cannabidiol was effective in reducing seizures. The brain’s endocannabinoid system contains receptors that respond to CBD, producing anticonvulsant effects. Being plant-derived and native to the brain’s own chemistry, CBD is therefore one of the most natural options for seizure treatment available today. Still, not many people took interest in CBD until 2013, when a CNN documentary special, Weed, hosted by the network’s chief medical correspondent, Dr. Sanjay Gupta, highlighted CBD’s effectiveness in combating seizures. Since then, demand for hemp oil products has exploded.

The effects of delta-9-THC and a synthetic agonist of the CB2 receptor were investigated in HCC.[15] Both agents reduced the viability of HCC cells in vitro and demonstrated antitumor effects in HCC subcutaneous xenografts in nude mice. The investigations documented that the anti-HCC effects are mediated by way of the CB2 receptor. Similar to findings in glioma cells, the cannabinoids were shown to trigger cell death through stimulation of an endoplasmic reticulum stress pathway that activates autophagy and promotes apoptosis. Other investigations have confirmed that CB1 and CB2 receptors may be potential targets in non-small cell lung carcinoma [16] and breast cancer.[17]
Throughout his lifetime, George Washington cultivated hemp at Mount Vernon for industrial uses. The fibers from hemp held excellent properties for making rope and sail canvas. In addition, hemp fibers could be spun into thread for clothing or, as indicated in Mount Vernon records, used in repairing the large seine nets Washington used in his fishing operation along the Potomac.

A limited number of studies have examined the effects of cannabis smoking on the respiratory system.[85] Chronic heavy marijuana smoking is associated with coughing, production of sputum, wheezing, and other symptoms of chronic bronchitis.[68] The available evidence does not support a causal relationship between cannabis use and chronic obstructive pulmonary disease.[86] Short-term use of cannabis is associated with bronchodilation.[87]
Hemp is considered by a 1998 study in Environmental Economics to be environmentally friendly due to a decrease of land use and other environmental impacts, indicating a possible decrease of ecological footprint in a US context compared to typical benchmarks.[59] A 2010 study, however, that compared the production of paper specifically from hemp and eucalyptus concluded that "industrial hemp presents higher environmental impacts than eucalyptus paper"; however, the article also highlights that "there is scope for improving industrial hemp paper production".[60] Hemp is also claimed to require few pesticides and no herbicides, and it has been called a carbon negative raw material.[61][62] Results indicate that high yield of hemp may require high total nutrient levels (field plus fertilizer nutrients) similar to a high yielding wheat crop.[63]

In the UK, the Department for Environment, Food and Rural Affairs treats hemp as a purely non-food crop, but with proper licensing and proof of less than 0.2% THC concentration, hemp seeds can be imported for sowing or for sale as a food or food ingredient.[18] In the U.S., imported hemp can be used legally in food products and, as of 2000, was typically sold in health food stores or through mail order.[16]
