There is a general inverse relationship in the resin of Cannabis between the amounts of THC present and the amount of the other principal cannabinoid, CBD. Whereas most drug strains contain primarily THC and little or no CBD, fiber and oilseed strains primarily contain CBD and very little THC. CBD can be converted to THC by acid catalyzed cyclization, and so could serve as a starting material for manufacturing THC. In theory, therefore, low-THC cultivars do not completely solve the problem of drug abuse potential. In practice, however, the illicit drug trade has access to easier methods of synthesizing THC or its analogues than by first extracting CBD from non-drug hemp strains.
For most people with epilepsy, diagnosis sets off a gauntlet of trial-and-error attempts to find the right medication. The process is tortuous, with seizures alternately dying down and flaring up while side effects— fatigue, nausea, liver damage, and more—develop without warning. This is partly due to the fact that “epilepsy” is actually a broad category that includes a number of distinct seizure disorders. About 30 medications approved by the U.S. Food and Drug Administration are currently used to treat these conditions, and when a person first begins having seizures, there is often much tinkering with combinations and dosages. I spent years battling side effects like vomiting, dizziness, drowsiness, and severe headaches, which were alleviated only by yet another prescription medication. Parents who endure enough sleepless nights caring for a sick child can become desperate for a cure.
In 2017, the cultivated area for hemp in the Prairie provinces include Saskatchewan with more than 56,000 acres (23,000 ha), Alberta with 45,000 acres (18,000 ha), and Manitoba with 30,000 acres (12,000 ha). Canadian hemp is cultivated mostly for its food value as hulled hemp seeds, hemp oils and hemp protein powders, with only a small fraction devoted to production of hemp fiber used for construction and insulation.
One of the most significant developments for the North American hemp industry was investment in hemp products by Anita and Gordon Roddick, founders of The Body Shop, a well known international chain of hair and body care retailers. This was a rather courageous and principled move that required overcoming American legal obstacles related to THC content. The Body Shop now markets an impressive array of hemp nutraceutical cosmetics (Fig. 39), and this has given the industry considerable credibility. The Body Shop has reported gross sales of about a billion dollars annually, and that about 4% of sales in 2000 were hemp products.
Since the beginning of the 20th century, most countries have enacted laws against the cultivation, possession or transfer of cannabis. These laws have impacted adversely on cannabis cultivation for non-recreational purposes, but there are many regions where handling of cannabis is legal or licensed. Many jurisdictions have lessened the penalties for possession of small quantities of cannabis so that it is punished by confiscation and sometimes a fine, rather than imprisonment, focusing more on those who traffic the drug on the black market.
Edible cannabis, however, is quickly making up ground as a go-to method for consuming medical marijuana. Indeed, some states with legal medical marijuana laws still forbid smoking marijuana. Instead, medical forms of the drug are only available in pill or capsule form. Oils and tinctures, which are made from extracting cannabinoids from herbaceous material, are also commonly prescribed in the form of cannabis edibles.
A USDA analysis of hemp, “Industrial hemp in the United States: Status and market potential,” was issued in 2000, and is available at www.ers.usda.gov/publications/ages001e/index.htm. This is anonymously-authored, therefore presumably represents a corporate or “official” evaluation. The conclusion was that “US markets for hemp fiber (specialty textiles, paper, and composites) and seed (in food or crushed for oil) are, and will likely remain, small, thin markets. Uncertainty about longrun demand for hemp products and the potential for oversupply discounts the prospects for hemp as an economically viable alternative crop for American farmers.” Noting the oversupply of hempseeds associated with Canada’s 12,000 ha in 1999, the report concluded that the long term demand for hemp products is uncertain, and predicts that the hemp market in the US will likely remain small and limited. With respect to textiles, the report noted the lack of a thriving textile flax (linen) US industry (despite lack of legal barriers), so that it would seem unlikely that hemp could achieve a better market status. With respect to hemp oil, the report noted that hemp oil in food markets is limited by its short shelf life, the fact that it can not be used for frying, and the lack of US Food and Drug Administration approval as GRAS (“generally recognized as safe”). Moreover, summarizing four state analyses of hemp production (McNulty 1995, Ehrensing 1998, Kraenzel et al. 1998, Thompson et al. 1998), profitability seemed doubtful.
The Spaniards brought hemp to the Americas and cultivated it in Chile starting about 1545. Similar attempts were made in Peru, Colombia, and Mexico, but only in Chile did the crop find success. In July 1605, Samuel Champlain reported the use of grass and hemp clothing by the (Wampanoag) people of Cape Cod and the (Nauset) people of Plymouth Bay told him they harvested hemp in their region where it grew wild to a height of 4 to 5 ft.  In May 1607, "hempe" was among the crops Gabriel Archer observed being cultivated by the natives at the main Powhatan village, where Richmond, Virginia is now situated; and in 1613, Samuell Argall reported wild hemp "better than that in England" growing along the shores of the upper Potomac. As early as 1619, the first Virginia House of Burgesses passed an Act requiring all planters in Virginia to sow "both English and Indian" hemp on their plantations. The Puritans are first known to have cultivated hemp in New England in 1645.
In 2014, I founded New Frontier Data, an analytics and business intelligence reporting group dedicated to the global cannabis industry, after more than 20 years in finance, industry analytics, intelligence reporting and emerging markets. As such, I have had the privilege of following hemp’s emergence and evolution. Half a decade later, this robust, environmentally friendly, low -cost-to-produce plant has become one of the most diversely applied and globally significant natural resources in the world. Here is a look at its applications across several mature industries:
But, uh, what is it that CBD is supposed to do? I visited a cannabis dispensary in Boulder to find out what the hype was all about. After passing an ID check, I was introduced to a “budtender” who pointed me to an impressive array of CBD products — tinctures, skin patches, drink powders, candies, salves, massage oil, lotions, “sexy time personal intimacy oil” and even vaginal suppositories to treat menstrual cramps.
Of the 20 known amino acids, hemp supplies them all, including the essential ones the body can’t produce, known as EAAs. About 65 percent of the protein in hemp seeds is edestin, a globulin protein that aids in digestion, similar to the globulin found in human blood plasma, and hemp seeds are the only place they’re found. The other third is made up of the protein albumin.
"Skunk" refers to several named strains of potent cannabis, grown through selective breeding and sometimes hydroponics. It is a cross-breed of Cannabis sativa and C. indica (although other strains of this mix exist in abundance). Skunk cannabis potency ranges usually from 6% to 15% and rarely as high as 20%. The average THC level in coffee shops in the Netherlands is about 18–19%.
On Oct. 22 and 23, KDA participated in four informational meetings about Industrial Hemp in Manhattan, Salina, Colby and Garden City hosted by Kansas Farmers Union. The presentation shared by KDA at those meetings can be seen here: KDA Industrial Hemp Presentation. Information on the event, including the video of the guest presenter, can be found on the Kansas Farmers Union website.
Cannabis smoke contains thousands of organic and inorganic chemical compounds. This tar is chemically similar to that found in tobacco smoke, and over fifty known carcinogens have been identified in cannabis smoke, including; nitrosamines, reactive aldehydes, and polycylic hydrocarbons, including benz[a]pyrene. Cannabis smoke is also inhaled more deeply than is tobacco smoke. As of 2015, there is no consensus regarding whether cannabis smoking is associated with an increased risk of cancer. Light and moderate use of cannabis is not believed to increase risk of lung or upper airway cancer. Evidence for causing these cancers is mixed concerning heavy, long-term use. In general there are far lower risks of pulmonary complications for regular cannabis smokers when compared with those of tobacco. A 2015 review found an association between cannabis use and the development of testicular germ cell tumors (TGCTs), particularly non-seminoma TGCTs. A 2015 analysis of six studies found little evidence that long-term or regular cannabis smoking was associated with lung cancer risk, though it could not rule out whether an association with heavy smoking exists. Another 2015 meta-analysis found no association between lifetime cannabis use and risk of head or neck cancer. Combustion products are not present when using a vaporizer, consuming THC in pill form, or consuming cannabis foods.
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." 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."
Cannabis, also known as marijuana among other names,[n 1] is a psychoactive drug from the Cannabis plant used for medical or recreational purposes. The main psychoactive part of cannabis is tetrahydrocannabinol (THC), one of 483 known compounds in the plant, including at least 65 other cannabinoids. Cannabis can be used by smoking, vaporizing, within food, or as an extract.
It’s a truism to state that pain is an inevitable part of life. And it’s true that we all, from time to time, experience pain that is short-lived and treatable. But those who deal with chronic pain know the debilitating, life-sucking reality of this condition. And traditional medications often come with long lists of side effects which can be as debilitating as the pain itself.
Pain management improves a patient’s quality of life throughout all stages of cancer. Through the study of cannabinoid receptors, endocannabinoids, and synthetic agonists and antagonists, the mechanisms of cannabinoid-induced analgesia have been analyzed.[Level of evidence:1iC] The CB1 receptor is found in the central nervous system (CNS) and in peripheral nerve terminals. CB2 receptors are located mainly in peripheral tissue and are expressed in only low amounts in the CNS. Whereas only CB1 agonists exert analgesic activity in the CNS, both CB1 and CB2 agonists have analgesic activity in peripheral tissue.[48,49]
