In the 1970s, the taxonomic classification of Cannabis took on added significance in North America. Laws prohibiting Cannabis in the United States and Canada specifically named products of C. sativa as prohibited materials. Enterprising attorneys for the defense in a few drug busts argued that the seized Cannabis material may not have been C. sativa, and was therefore not prohibited by law. Attorneys on both sides recruited botanists to provide expert testimony. Among those testifying for the prosecution was Dr. Ernest Small, while Dr. Richard E. Schultes and others testified for the defense. The botanists engaged in heated debate (outside of court), and both camps impugned the other's integrity. The defense attorneys were not often successful in winning their case, because the intent of the law was clear.
As noted above, hemp seed cake makes an excellent feed for animals. However, feeding entire plants is another matter, because the leaves are covered with the resin-producing glands. While deer, groundhogs, rabbits, and other mammals will nibble on hemp plants, mammals generally do not choose to eat hemp. Jain and Arora (1988) fed narcotic Cannabis refuse to cattle, and found that the animals “suffered variable degrees of depression and revealed incoordination in movement.” By contrast, Letniak et al. (2000) conducted an experimental trial of hemp as silage. No significant differences were found between yield of the hemp and of barley/oat silage fed to heifers, suggesting that fermenting hemp plants reduces possible harmful constituents.
Researchers in New Zealand have studied whether cannabis can be used to treat severe motor and vocal tics in those suffering from Tourette syndrome. The study concluded that subjects who took a controlled THC-CBD medicated spray showed marked improvement in the frequency and severity of motor and vocal tics post-treatment. Although the study is only a small clinical trial, it is one of the first to specifically analyze the effects of cannabis on Tourette syndrome.

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. Cannabinoids are under preliminary research for their potential to affect stroke.
I am currently going through red skin syndrome/topical steroid withdrawal. The only cure as of now is time(6 months to 3 years) and waiting out horrible eczema-like flares. My main issue is burning/tingling skin that is almost constant. Steroids close off blood vessels and when you stop them they 'wake' up causing this nerve discomfort/pain. I've been smoking medical cannabis for the duration of my recovery(1.5 years) and It's done wonders except that the flare is around my mouth and I'm afraid the smoking is causing more issues.. as well as helping. I need to step up my game and take a different approach. I am wondering how to go about using cbd but I don't know where to start and was wondering if you could help. Thank you
Canada is specialized on oilseed production and processing, so that hemp oil and grain are much more suitable than fiber. Because of the extensive development of oilseeds in Canada, there is extensive capacity to produce high-quality cold-pressed hemp oil. Canada in the last 5 years has made great advances in the growing, harvesting, and processing of hempseed, and indeed has moved ahead of the EU in the development of raw materials and products for the natural foods, nutraceuticals, and cosmetics industries. In the EU, a yield of 1 t/ha is considered good. In Canada, extraordinary yields of 1.5 t/ha have been realized, at least locally, although in the initial years of hempseed development in Canada yields were often less than 500 kg/ha. In 1999, the year of largest Canadian hemp acreage, yields averaged 900 kg/ha. (Ideally, hemp seed yield should be based on air dry weight—with about 12% moisture. Hemp yields are sometime uncertain, and could be exaggerated by as much as 50% when moist weights are reported.)
Cannabis is mostly used for recreation or as a medicinal drug, although it may also be used for spiritual purposes. In 2013, between 128 and 232 million people used cannabis (2.7% to 4.9% of the global population between the ages of 15 and 65). It is the most commonly used illegal drug both in the world and the United States. The countries with the highest use among adults as of 2018 are Zambia, the United States, Canada, and Nigeria. In 2016, 51% of people in the United States had ever used cannabis. About 12% had used it in the past year, and 7.3% had used it in the past month.
In 1924, Russian botanist D.E. Janichevsky concluded that ruderal Cannabis in central Russia is either a variety of C. sativa or a separate species, and proposed C. sativa L. var. ruderalis Janisch, and Cannabis ruderalis Janisch, as alternative names. In 1929, renowned plant explorer Nikolai Vavilov assigned wild or feral populations of Cannabis in Afghanistan to C. indica Lam. var. kafiristanica Vav., and ruderal populations in Europe to C. sativa L. var. spontanea Vav. In 1940, Russian botanists Serebriakova and Sizov proposed a complex classification in which they also recognized C. sativa and C. indica as separate species. Within C. sativa they recognized two subspecies: C. sativa L. subsp. culta Serebr. (consisting of cultivated plants), and C. sativa L. subsp. spontanea (Vav.) Serebr. (consisting of wild or feral plants). Serebriakova and Sizov split the two C. sativa subspecies into 13 varieties, including four distinct groups within subspecies culta. However, they did not divide C. indica into subspecies or varieties.
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.
exhaustion and pain that kept her on the couch much of the day. The 58-year-old Seattle speech coach didn’t want to take opioid pain-killers, but Tylenol wasn’t helping enough. Roth was intrigued when women in her online chat group enthused about a cannabis-derived oil called cannabidiol (CBD) that they said relieved pain without making them high. So Roth, who hadn’t smoked weed since college but lived in a state where cannabis was legal, walked into a dispensary and bought a CBD tincture. “Within a few hours of placing the drops in my mouth, the malaise and achiness that had plagued me for weeks lifted and became much more manageable,” she says. She took the drops several times a day and in a few weeks was back to her regular life.
Due to almost a century of misinformation about Cannabis, the distinction between Cannabis and its two primary species — hemp and marijuana — has become unclear to the many and some even consider the three plants to be one in the same. Because of this, the three terms are often used interchangeably, which has created difficulties when understanding the usage and benefits of Hemp vs Marijuana and Cannabis in general.
Newer antiemetics (e.g., 5-HT3 receptor antagonists) have not been directly compared with Cannabis or cannabinoids in cancer patients. However, the Cannabis-extract oromucosal spray, nabiximols, formulated with 1:1 THC:CBD was shown in a small pilot randomized, placebo-controlled, double-blinded clinical trial in Spain to treat chemotherapy-related N/V.[Level of evidence: 1iC] ASCO antiemetic guidelines updated in 2017 states that evidence remains insufficient to recommend medical marijuana for either the prevention or treatment of N/V in patients with cancer who receive chemotherapy or radiation therapy.
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.
Hemp paper are paper varieties consisting exclusively or to a large extent from pulp obtained from fibers of industrial hemp. The products are mainly specialty papers such as cigarette paper, banknotes and technical filter papers . Compared to wood pulp, hemp pulp offers a four to five times longer fibre, a significantly lower lignin fraction as well as a higher tear resistance and tensile strength. However, production costs are about four times higher than for paper from wood, so hemp paper could not be used for mass applications as printing, writing and packaging paper.
Stephanie, generally, I have patients take 20 to 150mg a day for sleep +/- anxiety. Start low and go slow. Know the dosages of your product. Usually 2/3 to 3/4 of the daily dose is 1-2 hours before bedtime, and the other portion is upon waking (to improve wakefulness during the day). Other factors such as stress, hormone replacement, other meds & medical conditions, etc. play a role along with individual differences. I own a compounding pharmacy, so we see a lot of unique needs. I can't give more specific advice in this forum, but there is help!

"Cannabinoids have been found to have antioxidant properties, unrelated to NMDA receptor antagonism. This new found property makes cannabinoids useful in the treatment and prophylaxis of wide variety of oxidation associated diseases, such as ischemic, age-related, inflammatory and autoimmune diseases. The cannabinoids are found to have particular application as neuroprotectants, for example in limiting neurological damage following ischemic insults, such as stroke and trauma, or in the treatment of neurodegenerative diseases, such as Alzheimer's disease, Parkinson's disease and HIV dementia.
In the United Kingdom, cultivation licences are issued by the Home Office under the Misuse of Drugs Act 1971. When grown for nondrug purposes, hemp is referred to as industrial hemp, and a common product is fibre for use in a wide variety of products, as well as the seed for nutritional aspects and for the oil. Feral hemp or ditch weed is usually a naturalized fibre or oilseed strain of Cannabis that has escaped from cultivation and is self-seeding.
In the end, companies like HempMedsPx are asking consumers simply to trust them. CBD oils are never subjected to systematic testing by any U.S. regulatory body. The FDA regulates all pharmaceutical labs in the country. But cannabis labs like the ones that HempMedsPx and others use are not, because cannabis is not federally recognized as a legal drug.
Although always sold at a premium price, hemp clothing has a natural appeal to a sector of the population. Hemp clothes are resistant to abrasion, but are typically abrasive. However, appropriate processing and blending with other natural fibers has significantly improved the “feel” of the product, and in China hemp textiles indistinguishable from fine linens in texture are available. Weaving of hemp fibers into textiles and apparel is primarily done in China, Hungary, Romania, Russia, and the Ukraine. Processing costs are higher for industrial hemp because the fibers vary from the standard specifications for fiber length and diameter established for the equipment used in most textile and apparel factories, necessitating the use of specialty machines. The North American hemp apparel industry today is based on fiber, yarn, and fabrics imported from Eastern Europe and China. The extraction technology and spinning facilities, to say nothing of much lower labor costs, make it very difficult for the potential development of a hemp textile industry in North America. The fact that spinning facilities for natural fibers are so concentrated in China is making it increasingly difficult to competitively produce hemp fabrics elsewhere. This of course lessens the value-added future of growing hemp for a potential textile industry in North America. It is possible, however, that new technologies could change this situation, and especially in the EU development is underway to establish a fledgling domestic hemp textile industry. In addition to textiles used in clothing, coarser woven cloth (canvas) is used for upholstery, bags, sacks, and tarpaulins. There is very little effort in North America to produce such woven products, and non-woven material (Fig. 15) can be more easily produced. Hempline in Ontario, the first firm to grow hemp for commercial purposes in North America since the second word war (starting with experimental cultivation in 1994), is the exception, and is concerned with production of fiber for upholstery and carpeting.
Today, 30 countries around the world allow farmers to grow industrial hemp, China being the largest producer and exporter. Canada, which produces hemp for food and toiletries, legalized the crop in 1996. The US, on the other hand, has restricted hemp production and categorized hemp in Schedule 1 of the Controlled Substances Act, attributing it as a relative of marijuana.
“The week before we tried it, we had 64 seizures,” Penny told me, noting those were only the visible seizures, while unseen neurological events would likely push the number into the hundreds. “We administered hemp oil, and the next week we logged in 28 seizures. ... The very next week, her second week on the hemp oil, we logged none.” Penny paused and repeated herself, as though she could still only half believe the miracle: “None.”
The Montana Department of Agriculture is not responsible for a pilot participant’s business plan or activities and will not be a mediator between pilot participants and any business associates or partners. We encourage interested individuals to contact a hemp trade association to learn more about marketing opportunities, such as the Hemp Industries Association or the National Hemp Association.
Without arguing the merits of the above contentions, we point out that the legitimate use of hemp for non-intoxicant purposes has been inhibited by the continuing ferocious war against drug abuse. In this atmosphere, objective analysis has often been lacking. Unfortunately both proponents and opponents have tended to engage in exaggeration. Increasingly, however, the world is testing the potential of hemp in the field and marketplace, which surely must be the ultimate arbiters. De Guzman (2001), noting the pessimistic USDA report, observed that “Nevertheless, others point to the potential of [the] market. Hemp products have a growing niche market of their own, and the market will remain healthy and be well supported with many competing brands.”
Indoor marijuana grows provide the most control over growing conditions. With a simple setup including a tent, proper lighting, and an air circulation system, home marijuana growers can produce consistent yields. Both soil and hydro systems can be utilized for indoor marijuana grows. Soil setups are generally cheaper and more forgiving, but hydro systems tend to be more common.
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]
However, it is important to note that the production of derivatives or products made from whole industrial hemp plants, including sprouts, or the leaves, flowers or bracts of those plants, cannot be authorized by a licence issued under the IHR. Most activities with whole industrial hemp plants, including sprouts, or with the leaves, flowers or bracts of the plant, fall outside of the application of the IHR. These activities are controlled under the CDSA and are not authorized under the IHR."
"Right now, any claims and dosing recommendations by any company making a CBD product for the medical marijuana market is purely anecdotal," he says. "Asking 100 people who use your product whether they feel better isn't real science. The products on the market are also different from what was used in the scientific studies that they are basing their claims upon. If a study found an anti-anxiety effect when dosing humans with synthetic CBD, that doesn't mean that your CBD oil that contains 18 percent CBD is going to reduce anxiety. It might even have the opposite effect."
This law provides a framework for commercial industrial hemp production in Montana following approval by the federal government. Provisions added to the 2014 Farm Bill (Section 7606) defined industrial hemp under federal law and recognized state agricultural departments' authority to develop research pilot programs to study the growth, cultivation, and/or marketing of industrial hemp.
Medical marijuana in the U.S. is controlled at the state level. Per federal law, cannabis is illegal as noted in the Controlled Substances Act, but the federal government has stated they will not actively prosecute patients and caregivers complying with state medical marijuana laws. However, use of medical marijuana outside of the state laws for illegal use or trafficking will not be tolerated by state or federal government.
Some manufacturers ship CBD products nationally, an illegal action which the FDA has not enforced in 2018, with CBD remaining as the subject of an FDA investigational new drug evaluation and is not considered legal as a dietary supplement or food ingredient as of November 2018. CBD is openly sold in head shops and health food stores in some states where such sales have not been explicitly legalized.
Hernandez said interactions between FDA-approved pharmaceuticals and CBD oils are a serious concern. “What we’ve found so far is that [CBD] can actually affect the levels of some of your epilepsy medications,” Hernandez told me. The diarrhea and vomiting associated with CBD oil ingestion can lower the levels of other drugs in patients’ bloodstreams, while the way the body absorbs CBD can raise the levels of certain medications.
One claim is that Hearst believed[dubious – discuss] that his extensive timber holdings were threatened by the invention of the decorticator which he feared would allow hemp to become a cheap substitute for the paper pulp used for newspaper. Historical research indicates this fear was unfounded because improvements of the decorticators in the 1930s – machines that separated the fibers from the hemp stem – could not make hemp fiber a cheaper substitute for fibers from other sources. Further, decorticators did not perform satisfactorily in commercial production.
Although hemp can be successfully grown continuously for several years on the same land, rotation with other crops is desirable. A 3- or preferably 4-year rotation may involve cereals, clover or alfalfa for green manure, maize, and hemp. In Ontario it has been recommended that hemp not follow canola, edible beans, soybeans or sunflowers. However, according to Bócsa and Karus (1998), “it matters little what crops are grown prior to hemp.”
There is certainly a need to utilize available germplasm sources in order to breed suitable cultivars for North America. A list of the 24 approved cultivars for the 2001 season in Canada is at www.hc-sc.gc.ca/hpb-dgps/therapeut/htmleng/hemp.html. Most of these are regulated by the European Organization of Economic Cooperation and Development (OECD). These cultivars are “approved” for use in Canada not on agricultural criteria, but merely on the basis that they meet the THC criterion. Indeed, most of these are unsuitable or only marginally suitable for Canada (Small and Marcus 2000), and only a very few Canadian cultivars to date have been created. In Canada, every acquisition of hemp grown at a particular place and time must be tested for THC content by an independent laboratory and, under the industrial hemp regulations, fields of hemp with more than 0.3% THC may require destruction (a slight degree of flexibility is generally exercised). Importation of experimental hemp lines (i.e. other than the approved cultivars) requires importation licenses (as well as phytosanitary clearance of the shipment by the Canadian Food Inspection Agency), and the importation licenses require an indication that the THC contents are low.
In the Australian states of Tasmania, Victoria, Queensland, and most recently, New South Wales, the state governments have issued licences to grow hemp for industrial use. The first to initiate modern research into the potential of cannabis was the state of Tasmania, which pioneered the licensing of hemp during the early 1990s. The state of Victoria was an early adopter in 1998, and has reissued the regulation in 2008.
