In Western Europe, the cultivation of hemp was not legally banned by the 1930s, but the commercial cultivation stopped by then, due to decreased demand compared to increasingly popular artificial fibers.[148] Speculation about the potential for commercial cultivation of hemp in large quantities has been criticized due to successful competition from other fibers for many products. The world production of hemp fiber fell from over 300,000 metric tons 1961 to about 75,000 metric tons in the early 1990s and has after that been stable at that level.[149]

Hemp plants are varieties of Cannabis sativa L. Hemp is a dioecious plant, which means it can be separated into male and female plants. Hemp plants have served a wide variety of purposes for more than 10,000 years for fiber (from the plant’s stems) and protein (from seeds). Hemp fibers can be used to make countless household items, including paper, clothing, furnishing fabric, rope, food, and building materials.

Answering the question “what is CBD oil” would be incomplete without mentioning the many CBD oil benefits. In addition to positively affecting the endocannabinoid system, CBD has been the focus of more than 23,000 published studies about cannabinoids in relation to various medical indications including anxiety, epilepsy, inflammation, cancer and chronic pain to name few. You can even find CBD for pets that is specially formulated to safely allow your pets to experience the natural benefits of CBD. For a more comprehensive look at these and other studies, visit our medical research and education page. Stay up-to-date on the latest developments in CBD and cannabis in our medical marijuana news section.
Oils are hot in the beauty world. As a beauty editor, I’ve slathered everything short of butter onto my face: argan, coconut, rosehip, sandalwood, chia, neroli, calendula, mandarin, macadamia, rice bran, seabuckthorn, patchouli, grapefruit seed, sesame seed, soybean, sweet almond, pomegranate seed, lemon myrtle, sunflower seed—even extra virgin olive oil from my pantry when I was desperate. I’ve washed my face with oil-based cleansers, and dabbed expensive mixtures being sold as “face oils” onto my skin in hopes of achieving that Instagram-ready glow. Contrary to popular belief, the right oil is actually good for your face and won’t clog your pores. Your skin needs a reasonable amount of oil to do its business; as a matter of fact, if you scrub away all your natural face oil (as I was prone to do with rubbing alcohol as a frustrated and misguided pizza-faced teen), you may actually be prone to more breakouts as your skin tries to make up for the imbalance. As cannabis meets up with the mainstream beauty world, cannabidiol (CBD) oil may be the next big thing.
Thermal Insulation. Thermal insulation products (Fig. 20, 21) are the third most important sector of the hemp industry of the EU. These are in very high demand because of the alarmingly high costs of heating fuels, ecological concerns about conservation of non-renewable resources, and political-strategic concerns about dependence on current sources of oil. This is a market that is growing very fast, and hemp insulation products are increasing in popularity. In Europe, it has been predicted that tens of thousands of tonnes will be sold by 2005, shared between hemp and flax (Karus et al. 2000).
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.
Inflammation is very common in both humans and dogs and can lead to chronic pain, arthritis, lupus, and other autoimmune diseases. Research has shown that CBD is able to help manage your dog’s pain and act as an anti-inflammatory and immune-boosting agent by activating our body’s Vanilloid receptor – the receptor known to mediate pain perception, inflammation, and body temperature.
Wild North American hemp is derived mostly from escaped European cultivated hemp imported in past centuries, perhaps especially from a revival of cultivation during World War II. Wild Canadian hemp is concentrated along the St. Lawrence and lower Great Lakes, where considerable cultivation occurred in the 1800s. In the US, wild hemp is best established in the American Midwest and Northeast, where hemp was grown historically in large amounts. Decades of eradication have exterminated many of the naturalized populations in North America. In the US, wild plants are rather contemptuously called “ditch weed” by law enforcement personnel. However, the attempts to destroy the wild populations are short-sighted, because they are a natural genetic reservoir, mostly low in THC. Wild North American plants have undergone many generations of natural adaptation to local conditions of climate, soil and pests, and accordingly it is safe to conclude that they harbor genes that are invaluable for the improvement of hemp cultivars. We have encountered exceptionally vigorous wild Canadian plants (Fig. 52), and grown wild plants from Europe (Fig. 53) which could prove valuable. Indeed, studies are in progress in Ontario to evaluate the agronomic usefulness of wild North American hemp. Nevertheless, present policies in North America require the eradication of wild hemp wherever encountered. In Europe and Asia, there is little concern about wild hemp, which remains a valuable resource.
One of CBD’s chief properties is its anticonvulsant nature. Clinical trials have shown that CBD is effective at reducing seizures in children, and the FDA is likely to approve Epidiolex, a pharmaceutical-grade version of CBD for this use, in summer 2018. Although CBD has been documented as an antiepileptic since 1881, CBD’s anticonvulsant mechanisms still remain unclear. Not enough studies have been conducted to understand this relationship fully. One possible explanation for CBD’s neuroprotective effects is its interaction with NMDA receptors, which play a key role in the overly active neuron activity that is a hallmark of epilepsy.
The 2018 Farm Bill changed federal policy regarding industry hemp, including the removal of hemp from the Controlled Substances Act and the consideration of hemp as an agricultural product. The bill legalized hemp under certain restrictions and expanded the definition of industrial hemp from the last 2014 Farm Bill. The bill also allows states and tribes to submit a plan and apply for primary regulatory authority over the production of hemp in their state or in their tribal territory. A state plan must include certain requirements, such as keeping track of land, testing methods,  and disposal of plants or products that exceed the allowed THC concentration.
Professors William Emboden, Loran Anderson, and Harvard botanist Richard E. Schultes and coworkers also conducted taxonomic studies of Cannabis in the 1970s, and concluded that stable morphological differences exist that support recognition of at least three species, C. sativa, C. indica, and C. ruderalis.[68][69][70][71] For Schultes, this was a reversal of his previous interpretation that Cannabis is monotypic, with only a single species.[72] According to Schultes' and Anderson's descriptions, C. sativa is tall and laxly branched with relatively narrow leaflets, C. indica is shorter, conical in shape, and has relatively wide leaflets, and C. ruderalis is short, branchless, and grows wild in Central Asia. This taxonomic interpretation was embraced by Cannabis aficionados who commonly distinguish narrow-leafed "sativa" strains from wide-leafed "indica" strains.[73]
We recommend refrigeration out of an abundance of caution. Prolonged exposure to sunlight or heat can cause the oil to prematurely spoil. Heat above 160°F will cause the PurCBD+ to breakdown and become ineffective. Refrigeration is the simplest way to ensure the longest possible shelf life. For most people, however, refrigeration isn't needed—it’s just ideal.
Although still considered to be quite controversial, a growing number of pet owners are discovering the benefits of CBD for dogs, especially their chronically ill companions. In this article I'll introduce you to some of the proven and assumed health benefits of CBD oil for dogs so that you can decide for yourself if this is right for your pooch or not.

Experimental studies have also been conducted in order to assess the effect of cannabis use on schizophrenia. D’Souza et al. (2004) administered varying levels of the main ingredient in cannabis to healthy individuals with a history of cannabis exposure (but not abuse) and found that the subjects in the study displayed both positive and negative symptoms associated with schizophrenia, although all symptoms disappeared by about 3 h. D’Souza et al. (2005) conducted a follow-up study in which they followed the same protocol, but with clinically stable schizophrenia patients. Again, they found brief increases in positive symptoms, even if the patients were already taking antipsychotics.

American industrialists led by newspaper mogul William Randolph Hearst (who owned vast timberlands) and DuPont executives, who’d begun processing petroleum and wood for plastics, became disgruntled by the way hemp cut into their market shares. A 1994 Vegetarian Times article2 describes the group’s devastatingly successful tactics for twisting the public’s perception of hemp:
Hi…I read your statement about hemp being a cream that takes pain away. Living in Oregon there’s no talk about “hemp” but I don’t doubt your experience with it..and I’m wondering where you found it..so that maybe I can get a jar of it and see if it would help my aches and pains….I would really appreciate your response…and thanks for your “reply” that motivated me to write to you..
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.[103][104] Cannabinoids are under preliminary research for their potential to affect stroke.[105]
The cultivation of hemp in the EU is heavily weighted toward fiber production over oilseed production. In 1999, the EU produced about 27,000 t of hemp fiber, but only about 6,200 t of hemp seeds, mostly in France, and 90% of this was used as animal feed (Karus et al. 2000). The seeds (Fig. 33) have traditionally been employed as bird and poultry feed, but feeding the entire seeds to livestock has been considered to be a poor investment because of the high cost involved (although subsidization in Europe allows such usage, especially in France where hemp seeds are not legally permitted in human food). As pointed out later, higher yield and better harvesting practices may make whole hempseed an economical livestock feed. Moreover, seed cake left after expressing the oil is an excellent feed. Efforts are underway in Europe to add value in the form of processed products for hemp, especially cosmetics and food but, as noted below, the North American market is already quite advanced in oilseed applications.

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 Western Europe, the cultivation of hemp was not legally banned by the 1930s, but the commercial cultivation stopped by then, due to decreased demand compared to increasingly popular artificial fibers.[148] Speculation about the potential for commercial cultivation of hemp in large quantities has been criticized due to successful competition from other fibers for many products. The world production of hemp fiber fell from over 300,000 metric tons 1961 to about 75,000 metric tons in the early 1990s and has after that been stable at that level.[149]
The plant was first given its taxonomic identification by Carl Linnaeus in 1753 and thoroughly described to Westerners in the 1800s, when the medical doctor William O'Shaughnessy gave a report to the Medical and Physical Society of Calcutta in India in 1839. The doctor described its effects on people and did a few case reports on "gunjah," the Indian name for the drug.
Another claim is that Mellon, Secretary of the Treasury and the wealthiest man in America at that time, had invested heavily in DuPont's new synthetic fiber, nylon, and believed[dubious – discuss] that the replacement of the traditional resource, hemp, was integral to the new product's success.[128][133][134][135][136][137][138][139] The company DuPont and many industrial historians dispute a link between nylon and hemp, nylon became immediately a scarce commodity.[clarification needed] Nylon had characteristics that could be used for toothbrushes (sold from 1938) and very thin nylon fiber could compete with silk and rayon in various textiles normally not produced from hemp fiber, such as very thin stockings for women.[132][140][141][142][143]
