Although the environmental and biodiversity benefits of growing hemp have been greatly exaggerated in the popular press, C. sativa is nevertheless exceptionally suitable for organic agriculture, and is remarkably less “ecotoxic” in comparison to most other crops (Montford and Small 1999b). Figure 50 presents a comparison of the ecological friendliness of Cannabis crops (fiber, oilseed, and narcotics) and 21 of the world’s major crops, based on 26 criteria used by Montford and Small (1999a) to compare the ecological friendliness of crops.
Selective breeding of cannabis plants has expanded and diversified as commercial and therapeutic markets develop. Some growers in the U.S. succeeded in lowering the proportion of CBD-to-THC to accommodate customers who preferred varietals that were more mind-altering due to the higher THC and lower CBD content. Hemp is classified as any part of the cannabis plant containing no more than 0.3% THC in dry weight form (not liquid or extracted form).
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.
Medical reviews published in 2017 and 2018 incorporating numerous clinical trials concluded that cannabidiol is an effective treatment for certain types of childhood epilepsy. An orally administered cannabidiol solution (brand name Epidiolex) was approved by the US Food and Drug Administration in June 2018 as a treatment for two rare forms of childhood epilepsy, Lennox-Gastaut syndrome and Dravet syndrome.
The etymology is uncertain but there appears to be no common Proto-Indo-European source for the various forms of the word; the Greek term kánnabis is the oldest attested form, which may have been borrowed from an earlier Scythian or Thracian word. Then it appears to have been borrowed into Latin, and separately into Slavic and from there into Baltic, Finnish, and Germanic languages. Following Grimm's law, the "k" would have changed to "h" with the first Germanic sound shift, after which it may have been adapted into the Old English form, hænep. However, this theory assumes that hemp was not widely spread among different societies until after it was already being used as a psychoactive drug, which Adams and Mallory (1997) believe to be unlikely based on archaeological evidence. Barber (1991) however, argued that the spread of the name "kannabis" was due to its historically more recent drug use, starting from the south, around Iran, whereas non-THC varieties of hemp are older and prehistoric. Another possible source of origin is Assyrian qunnabu, which was the name for a source of oil, fiber, and medicine in the 1st millennium BC.
Cannabis is an annual, dioecious, flowering herb. The leaves are palmately compound or digitate, with serrate leaflets. 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.
Traditionally, hemp fiber has been a very coarse fiber when raw, which made it well suited to rope but less than ideal for clothing designed to be worn against delicate human skin. Advances in breeding of the plants and treatment/processing of the fibers have resulted in a much finer, softer hemp fiber, which is ideal for weaving into hemp clothing, fabrics and rope. Watch the video on Hemp for victory to learn more about the importance of hemp during war times.
One study in mice and rats suggested that cannabinoids may have a protective effect against the development of certain types of tumors. During this 2-year study, groups of mice and rats were given various doses of THC by gavage. A dose-related decrease in the incidence of hepatic adenoma tumors and hepatocellular carcinoma (HCC) was observed in the mice. Decreased incidences of benign tumors (polyps and adenomas) in other organs (mammary gland, uterus, pituitary, testis, and pancreas) were also noted in the rats. In another study, delta-9-THC, delta-8-THC, and cannabinol were found to inhibit the growth of Lewis lung adenocarcinoma cells in vitro and in vivo . In addition, other tumors have been shown to be sensitive to cannabinoid-induced growth inhibition.[5-8]
When privacy isn’t a requirement, outdoor cannabis grows can provide many advantages over indoor operations. Sunlight is the single most important factor for successful outdoor marijuana growing. It’s important to choose a plot with total sunshine throughout the day. Therefore, cannabis growers in the northern hemisphere will want plots with southern exposure, exposing marijuana plants to the sun’s arc across the sky.
One of the biggest players in this new industry is Medical Marijuana, Inc., a company formed in 2009 that operates out of Poway, California, just north of San Diego. It has played a leading role in the so-called Green Rush, as businesses have moved quickly to capitalize on the gradual legalization of marijuana for medical and recreational purposes by states across the country. The company’s spokesman, Andrew Hard, boasted that Medical Marijuana, Inc., “created the CBD industry and was first to market with CBD products.” Through its various subsidiaries, Medical Marijuana, Inc. sells some of the most recognizable products on the cannabis market— everything from Cibaderm CBD-infused shampoo to CanChew chewing gum. In 2014, the company generated $14.5 million in revenue.
Millennia of selective breeding have resulted in varieties that display a wide range of traits; e.g. suited for a particular environments/latitudes, producing different ratios and compositions of terpenoids and cannabinoids (CBD, THC, CBG, CBC, CBN...etc.), fibre quality, oil/seed yield etc. Hemp grown for fiber is planted closely, resulting in tall, slender plants with long fibers.
Preclinical research suggests that emetic circuitry is tonically controlled by endocannabinoids. The antiemetic action of cannabinoids is believed to be mediated via interaction with the 5-hydroxytryptamine 3 (5-HT3) receptor. CB1 receptors and 5-HT3 receptors are colocalized on gamma-aminobutyric acid (GABA)-ergic neurons, where they have opposite effects on GABA release. There also may be direct inhibition of 5-HT3 gated ion currents through non–CB1 receptor pathways. CB1 receptor antagonists have been shown to elicit emesis in the least shrew that is reversed by cannabinoid agonists. The involvement of CB1 receptor in emesis prevention has been shown by the ability of CB1 antagonists to reverse the effects of THC and other synthetic cannabinoid CB1 agonists in suppressing vomiting caused by cisplatin in the house musk shrew and lithium chloride in the least shrew. In the latter model, CBD was also shown to be efficacious.[37,38]
By 1938, Popular Mechanics called hemp the “Billion Dollar Crop,”1 praising its potential to produce 25,000 different products, as high as $192 billion in today’s market and capable of producing four times the paper per acre than trees. Farmers from the Midwest to the East coast harvested more than 150,000 acres for the war’s Hemp for Victory Program, implemented by the USDA from 1942 through 1946, but rumblings by the competition had already started.

Access to viable seed may present a challenge for research programs and commercial growers. To implement commercial and research hemp programs, farmers need access to seeds that are guaranteed to produce plants that fall under the legal definition of hemp. These seeds can be difficult to obtain, however, because hemp is still regulated under the federal Controlled Substances Act. In response to this problem, Colorado’s governor sent a letter to the U.S. secretary of agriculture in 2014 requesting the federal government address hemp seed regulations.
Marijuana, also called pot, weed, ganja, mary jane, and a host of other nicknames, is made from the Cannabis plant, which has three species: Cannabis sativa; Cannabis indica and Cannabis ruderalis. The flowering plant, which can grow to 16 feet (5 meters) high, likely originated in the Central Asian steppe, near the Altai or Tian Shian Mountains, and was first cultivated in China and India, according to "Cannabis and Cannabinoids: Pharmacology, Toxicology and Therapeutic Potential," (Routledge, 2002).
Fig. 11. Frequency histograms of THC concentration in germplasm collections. Left, collection of E. Small and D. Marcus; of the 167 accessions, 43% had THC levels >0.3%. Right, the collection of the Vavilov Institute, St. Petersburg; of the 278 accessions for which chemical analyses were reported in Anonymous (1975), about 55% had THC levels >0.3%.
Cannabis (also called pot, marijuana, weed, dope, grass, mull, dak, hash, smoke, buds, skunk, cabbage, ganja, reefer) is the most commonly used illegal drug in New Zealand. Cannabis comes from the Cannabis Sativa plant and is used both for recreational and medicinal purposes. As a recreational drug, it can be used in a dried plant, resin, or oil form. The potency of cannabis depends on it's concentration of THC, which is higher in resin and oil than in the dried plant. The psychoactive potency of cannabis depends on its concentration of THC, which is higher in resin and hash oil. Cannabis is widely available in New Zealand.
Separate levels of evidence scores are assigned to qualifying human studies on the basis of statistical strength of the study design and scientific strength of the treatment outcomes (i.e., endpoints) measured. The resulting two scores are then combined to produce an overall score. An overall level of evidence score cannot be assigned to cannabinoids because there has been insufficient clinical research. For an explanation of possible scores and additional information about levels of evidence analysis of CAM treatments for people with cancer, refer to Levels of Evidence for Human Studies of Integrative, Alternative, and Complementary Therapies.
As a consumer, you can look at the manufacturer's website to see whether they batch-test their products, or ask them directly. You could also send a sample of your CBD oil to a testing facility yourself, something Bonn-Miller says he would do if he were trying to treat someone with a severe issue such as epilepsy. Testing can also determine whether the product contains pesticides, heavy metals, or other toxins.
Hemp is plagued by bird predation, which take a heavy toll on seed production. The seeds are well known to provide extremely nutritious food for both wild birds and domestic fowl. Hunters and birdwatchers who discover wild patches of hemp often keep this information secret, knowing that the area will be a magnet for birds in the fall when seed maturation occurs. Increasingly in North America, plants are being established to provide habitat and food for wildlife. Hemp is not an aggressive weed, and certainly has great potential for being used as a wildlife plant. Of course, current conditions forbid such usage in North America.
The CBD oil needs to be taken twice a day everyday. The dosage depends on symptoms and it takes 30 days to awken your natural cannabis system after you begin taking the oil. I personally use Hemp works CBD oil in the 750 strength and only need 5 drops sublingual 2 times daily and results are many. Problem with oil and alz.patients is getting them to hold oil under tongue for 60 seconds. We have just began to get my dad on it. He too is in a nursing home in the state of florida and they cannot deny him any medication my mom has requested that he receive. If she is not their they are supposed to administer and she will call them to make sure he gets it. He is not 30 days into dosing yet so I don't have any results to speak of. I do know that since he has started he has had no more bladder infection and has not fallen in 3 weeks. That's a record for him so we will continue to monitor. Best of luck to you and a lot is going to depend on the state your mom is in and what the state laws are concerning her rights or the rights of whom has her medical power of attorney
CBD may also enhance uptake of cytotoxic drugs into malignant cells. Activation of the transient receptor potential vanilloid type 2 (TRPV2) has been shown to inhibit proliferation of human glioblastoma multiforme cells and overcome resistance to the chemotherapy agent carmustine.  One study showed that coadministration of THC and CBD over single-agent usage had greater antiproliferative activity in an in vitro study with multiple human glioblastoma multiforme cell lines. In an in vitro model, CBD increased TRPV2 activation and increased uptake of cytotoxic drugs, leading to apoptosis of glioma cells without affecting normal human astrocytes. This suggests that coadministration of CBD with cytotoxic agents may increase drug uptake and potentiate cell death in human glioma cells. Also, CBD together with THC may enhance the antitumor activity of classic chemotherapeutic drugs such as temozolomide in some mouse models of cancer.[13,33] A meta-analysis of 34 in vitro and in vivo studies of cannabinoids in glioma reported that all but one study confirmed that cannabinoids selectively kill tumor cells.
It’s easy to see why vaping has become such a popular method for consuming marijuana. The method is remarkably discrete and produces none of the telltale “weed smells” that often betray cannabis users. Vape pens and other hand-held devices are portable and convenient. They’re free of many of the harsh marijuana plant compounds that can harm your lung health, like tars. And companies are getting better at crafting high-quality, flavorful vape cartridges with a wide array of cannabinoid profiles.
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.
Low concentrations of CBD aren’t the only concern, either. Cannabis plants are hardy and tough, and their thick stalks possess a special property: bioremediation. When grown in contaminated soil, hemp plants absorb heavy metals and other chemical waste, effectively cleansing the terrain. While all plants absorb some chemicals from the soil, the structure, size, and genetic makeup of hemp make it especially adept at this task. Cannabis is so effective that crops of industrial hemp were planted in the aftermath of the 1986 Chernobyl disaster to help purify heavily irradiated soil. When hemp stalks are used for fiber, paper, and other nonconsumptive industrial purposes, the contaminants absorbed into the plants pose no threat to humans.
In 2013, BMW announced its newest electric car, the i3. Using low-weight hemp in its interior, the i3 weighs 800 pounds less than its market competitors. The Kestrel, created by Canadian Motive Industries, uses polymer resin-infused hemp stalks to replace fiberglass in the body of the vehicle. From this replacement, consumers can expect a dramatic reduction in weight, improved efficiency and the appeal of an ecologically sustainable vehicle.
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.
CBD Isolates/Concentrates: Anyone familiar with smoking hash or other cannabis concentrates like wax and BHO will be no stranger to this delivery method. Simply sprinkle some into a vaporizer or water pipe, ignite, inhale, and enjoy! We find that this option is useful for individuals looking to elevate their regular consumption of CBD-rich cannabis flowers or other smokable herbs.
In November 2015, Uttarakhand became the first state of India to legalize the cultivation of hemp for industrial purposes. Usage within the Hindu and Buddhist cultures of the Indian subcontinent is common, with many street vendors in India openly selling products infused with cannabis, and traditional medical practitioners in Sri Lanka selling products infused with cannabis for recreational purposes and well as for religious celebrations. It was criminalized in the Indian subcontinent by the Dutch and then the British. India and Sri Lanka have allowed cannabis to be taken in the context of traditional culture for recreational/celebratory purposes and also for medicinal purposes.
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.
