Mike, what kind of breast cancer (invasive ductal, I presume)? How many of her lymph nodes were positive? How big was the primary tumor? Reason I ask is that in women with Stage I or IIA tumors that are estrogen-and progesterone-receptor-positive and HER2-negative (ER+/PR+/HER2-) with three or fewer positive lymph nodes, there is a genomic assay test on a sample of the tumor, called OncotypeDX, that will tell doctors whether chemo is necessary or would even work at all. Medicare covers that test 100%.That type of breast cancer mentioned above, which I had as Stage IA, is treated in postmenopausal women with anti-estrogen drugs called aromatase inhibitors(aka AIs: anastrazole, letrozole, or exemestane)which have as a side effect joint pain. CBD oil is effective for this joint pain it is not, I repeat, NOT a substitute for chemo, radiation or these anti-estrogen drugs.So don’t assume your mom’s cancer will require chemo; but if it does, CBD helps with those side effects as well. If she lives in a state where medical marijuana is legal, there are doctors who sub-specialize in certifying applications for a medical marijuana card, and in the interim before the card is issued can advise as to the appropriate dose of CBD oil (legal and over-the-counter in all 50 states). Some (though not most) medical oncologists will certify their own patients’ medical marijuana card applications so she need not seek out another doctor; and will advise the appropriate dose for her symptoms. Once she gets her card, the “budtenders” in the licensed dispensaries can advise her as to the right CBD product (with or without THC), strength, and dosage. If she lives in a state where recreational weed is legal, the “budtenders” in the marijuana shops can steer her to the right strength of CBD oil and the right dosage.
“Geotextiles” or “agricultural textiles” include (1) ground-retaining, biodegradable matting designed to prevent soil erosion, especially to stabilize new plantings while they develop root systems along steep highway banks to prevent soil slippage (Fig. 32); and (2) ground-covers designed to reduce weeds in planting beds (in the manner of plastic mulch). At present the main materials used are polymeric (polythene, spun-blown polypropylene) and some glass fiber and natural fibers. Both woven and non-woven fibers can be applied to geotextiles; woven and knitted materials are stronger and the open structure may be advantageous (e.g. in allowing plants to grow through), but non-wovens are cheaper and better at suppressing weeds. Flax and hemp fibers exposed to water and soil have been claimed to disintegrate rapidly over the course of a few months, which would make them unacceptable for products that need to have long-term stability when exposed to water and oil. Coco (coir) fiber has been said to be much more suitable, due to higher lignin content (40%–50%, compared to 2%–5% in bast fibers); these are much cheaper than flax and hemp fibers (Karus et al. 2000). However, this analysis does not do justice to the developing hemp geotextile market. Production of hemp erosion control mats is continuing in both Europe and Canada. Given the reputation for rot resistance of hemp canvas and rope, it seems probable that ground matting is a legitimate use. Moreover, the ability to last outdoors for many years is frequently undesirable in geotextiles. For example, the widespread current use of plastic netting to reinforce grass sod is quite objectionable, the plastic persisting for many years and interfering with lawn care. Related to geotextile applications is the possibility of using hemp fiber as a planting substrate (biodegradable pots and blocks for plants), and as biodegradable twine to replace plastic ties used to attach plants to supporting poles. Still another consideration is the “green ideal” of producing locally for local needs; by this credo, hemp is preferable in temperate regions to the use of tropical fibers, which need to be imported.

Infusions: Research and opportunity have driven chefs and chemists to infuse CBD into all sorts of readily usable products, such as edibles to elixirs, sublingual sprays, capsules and even topicals. Much like concentrates, each infusion sports specific combinations or isolations of CBD, THC, and other cannabinoids, allowing users to pick and choose products that suit their exact needs. CBD topicals, for example, are incredibly effective when applied to surface-level problems like bruises, joint aches, and headaches, and have been scientifically proven to successfully combat skin-based issues including pruritus with far broader implications.
The US Office of National Drug control Policy issued a statement on industrial hemp in 1997 (www.whitehousedrugpolicy.gov/policy/hemp%5Fold.html) which included the following: “Our primary concern about the legalization of the cultivation of industrial hemp (Cannabis sativa) is the message it would send to the public at large, especially to our youth at a time when adolescent drug use is rising rapidly... The second major concern is that legalizing hemp production may mean the de facto legalization of marijuana cultivation. Industrial hemp and marijuana are the product of the same plant, Cannabis sativa... Supporters of the hemp legalization effort claim hemp cultivation could be profitable for US farmers. However, according to the USDA and the US Department of Commerce, the profitability of industrial hemp is highly uncertain and probably unlikely. Hemp is a novelty product with limited sustainable development value even in a novelty market... For every proposed use of industrial hemp, there already exists an available product, or raw material, which is cheaper to manufacture and provides better market results.... Countries with low labor costs such as the Philippines and China have a competitive advantage over any US hemp producer.”
ECS is made up of endocannabinoids and the receptors associated with them. These receptors are literally found from head to toe, and are in such places as the glands, organs, and the brain. While receptors and endocannabinoids are located in all parts of the body, they have different functions depending upon where they are located, with the primary role being to regulate what is referred to as homeostasis or the regulation of the body so that it is at equilibrium.
Cannabidiol (CBD) is a naturally occurring compound found in the resinous flower of cannabis, a plant with a rich history as a medicine going back thousands of years. Today the therapeutic properties of CBD are being tested and confirmed by scientists and doctors around the world. A safe, non-addictive substance, CBD is one of more than a hundred “phytocannabinoids,” which are unique to cannabis and endow the plant with its robust therapeutic profile.
Cannabinoids may offer significant “side benefits” beyond analgesia. These include anti-emetic effects, well established with THC, but additionally demonstrated for CBD (Pertwee 2005), the ability of THC and CBD to produce apoptosis in malignant cells and inhibit cancer-induced angiogenesis (Kogan 2005; Ligresti et al 2006), as well as the neuroprotective antioxidant properties of the two substances (Hampson et al 1998), and improvements in symptomatic insomnia (Russo et al 2007).
• Is there a batch number? You know how you check your raw chicken or bagged lettuce every time there's a recall to make sure the one you bought isn't going to make you sick? You should be able to do that with CBD products too. "This is a huge indicator as to whether they are following good manufacturing practices," says Beatty. "There should be a way to identify this product in case it was improperly made so the company can carry out a recall."

"Given these data limitations, available trade statistics indicate that the value of U.S. imports under categories actually labeled 'hemp,' such as hemp seeds and fibers—which are more often used as inputs for use in further manufacturing—was nearly $78.2 million in 2015. Compared to 2005, when the value of imports totaled $5.6 million, imported hemp products for use as inputs and ingredients has increased sharply. However, import volumes for other products, such as hemp oil and fabrics, are lower (Table 1). Trade data are not available for finished products, such as hempbased clothing or other products including construction materials, carpets, or paper products.
I am a former family doctor and naturopathic physician as well as a medical editor and author, working mostly in academic research. In my practice I have always focused on natural medicine and helped my patients of all ages who haven’t responded to traditional treatments. I also have written a significant number of articles in botanical medicine, addiction, drugs. As of now I'm focused on cannabis researches, especially on cannabidiol, its health benefits and how it can improve life of people with severe diseases. You can read my articles here on CBDreamers
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.
Researchers think that CBD interacts with receptors in your brain and immune system. Receptors are tiny proteins attached to your cells that receive chemical signals from different stimuli and help your cells respond. This creates anti-inflammatory and painkilling effects that help with pain management. This means that CBD oil may benefit people with chronic pain, such as chronic back pain.
Frequent questions have been raised as to whether psychoactive drugs may be adequately blinded (masked) in randomized clinical trials. Internal review and outside analysis have confirmed that blinding in Sativex spasticity studies has been effective (Clark and Altman 2006; Wright 2005). Sativex and its placebo are prepared to appear identical in taste and color. About half of clinical trial subjects reported previous cannabis exposure, but results of two studies (Rog et al 2005; Nurmikko et al 2007) support the fact that cannabis-experienced and naïve patients were identical in observed efficacy and adverse event reporting
The glutamatergic system is integral to development and maintenance of neuropathic pain, and is responsible for generating secondary and tertiary hyperalgesia in migraine and fibromyalgia via NMDA mechanisms (Nicolodi et al 1998). Thus, it is important to note that cannabinoids presynaptically inhibit glutamate release (Shen et al 1996), THC produces 30%–40% reduction in NMDA responses, and THC is a neuroprotective antioxidant (Hampson et al 1998). Additionally, cannabinoids reduce hyperalgesia via inhibition of calcitonin gene-related peptide (Richardson et al 1998a). As for Substance P mechanisms, cannabinoids block capsaicin-induced hyperalgesia (Li et al 1999), and THC will do so at sub-psychoactive doses in experimental animals (Ko and Woods 1999). Among the noteworthy interactions with opiates and the endorphin/enkephalin system, THC has been shown to stimulate beta-endorphin production (Manzanares et al 1998), may allow opiate sparing in clinical application (Cichewicz et al 1999), prevents development of tolerance to and withdrawal from opiates (Cichewicz and Welch 2003), and rekindles opiate analgesia after a prior dosage has worn off (Cichewicz and McCarthy 2003). These are all promising attributes for an adjunctive agent in treatment of clinical chronic pain states.
Berenson looks, too, at the early results from the state of Washington, which, in 2014, became the first U.S. jurisdiction to legalize recreational marijuana. Between 2013 and 2017, the state’s aggravated-assault rate rose seventeen per cent, which was nearly twice the increase seen nationwide, and the murder rate rose forty-four per cent, which was more than twice the increase nationwide. We don’t know that an increase in cannabis use was responsible for that surge in violence. Berenson, though, finds it strange that, at a time when Washington may have exposed its population to higher levels of what is widely assumed to be a calming substance, its citizens began turning on one another with increased aggression.
CBD is readily obtainable in most parts of the United States, though its exact legal status is in flux. All 50 states have laws legalizing CBD with varying degrees of restriction, and while the federal government still considers CBD in the same class as marijuana, it doesn’t habitually enforce against it. In December 2015, the FDA eased the regulatory requirements to allow researchers to conduct CBD trials. Currently, many people obtain CBD online without a medical cannabis license. The government’s position on CBD is confusing, and depends in part on whether the CBD comes from hemp or marijuana. The legality of CBD is expected to change, as there is currently bipartisan consensus in Congress to make the hemp crop legal which would, for all intents and purposes, make CBD difficult to prohibit.
In Japan, hemp was historically used as paper and a fiber crop. There is archaeological evidence cannabis was used for clothing and the seeds were eaten in Japan back to the Jōmon period (10,000 to 300 BC). Many Kimono designs portray hemp, or asa (Japanese: 麻), as a beautiful plant. In 1948, marijuana was restricted as a narcotic drug. The ban on marijuana imposed by the United States authorities was alien to Japanese culture, as the drug had never been widely used in Japan before. Though these laws against marijuana are some of the world's strictest, allowing five years imprisonment for possession of the drug, they exempt hemp growers, whose crop is used to make robes for Buddhist monks and loincloths for Sumo wrestlers. Because marijuana use in Japan has doubled in the past decade, these exemptions have recently been called into question.
If your intention is to help treat chronic pain, then you may want to start out with a lower dose, and then proceed from there. If you notice effective results, you can downsize the dose, or likewise you can always up the dose until positive results are achieved. The key is to only increase your dosage in small increments so that you are able to pinpoint exactly how much CBD oil it takes to treat your condition. Be advised, though, that you should not exceed the recommended daily doses that are listed on the bottle and you should consult with a physician.
Hi, I have had spondylolisthesis since age 11 which left me with extreme nerve pain...restless leg syndrome. Had 3 spinal ops and also had hip surgery 2 years ago. have asthma and hypothyroidism. I can deal with everything else but this nerve pain is insane. Used Gabapentin for 9 years and now its not in the market in Nairobi, Kenya where I live. Am on Lyrica, which is not working. I started Cbd oil in August but now found my body has become immune to the effects of pain releif I was getting. Can anyone suggest what strength oil/cbd supplement I should aim for? Currently am making flapjacks with weed, have one every night but this makes me high which I dont want. I still wake up in pain at night, please help.
Fig. 8. Scanning electron micrographs of the abaxial surface of a perigonal bract (which envelops the fruit). These bracts are the most intoxicating part of the plant, and may contain 20% THC, dry weight. The resin is synthesized both in stalked and sessile glands. Multicellular secretory glands (of phallic appearance), some broken stalks of these (note cellular appearance), and unicellular cystolith hairs (claw-like structures) are pictured. Fig. 9. Some important cannabinoids of cannabis resin. D9-THC (delta-9 tetrahydrocannabinol) is the chief intoxicant chemical and predominates in intoxicant strains, while the isomer D8-THC is usually present in no more than trace amounts. CBD (cannabidiol) is the chief non-intoxicant chemical, and predominates in non-intoxicant strains; it has sedative effects. The non-intoxicant CBN (cannabinol) is a frequent degradation or oxidation product. The non-intoxicant cannabichromene (CBC) is typically found in trace amounts in intoxicant strains. The non-intoxicant cannabigerol (CBG) is considered to be a precursor of the other cannbinoids (see Fig. 10).
The Food and Drug Administration (FDA) does not consider CBD or products that contain CBD to be dietary supplements. This is because CBD has been studied and approved for use as a new drug to treat epilepsy, which means it is outside the definition of a dietary supplement.5 There may be products available that are marked as dietary supplements, however the amount of cannabidiol they claim to contain may not be accurate.
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.
In response to the FDA’s historic decision, the Drug Enforcement Administration (DEA) announced in September 2018 that it had removed Epidiolex from Schedule I classification, a category reserved for dangerous drugs with no medical value. Henceforth, Epidiolex would be considered a Schedule V drug, the least dangerous designation under the Controlled Substances Act.
I use cbd oil every day. I refuse to go without it. I have no arthritic pain at all anymore. I had a hip replacement 3 years ago. I am in need of the other one to be replaced. I was laying awake crying at night because of my hip pain. After I started using the oil my hip has quit aching. I sometimes forget I even have a problem with it or my arthritis. Had I known about the oil before I had my hip replaced I never would have had the surgery. I am pain free. I use hemp oil. There are 20 mg of cannabiniol in each 1 ml dose.
Late last year, the commissioner of the Food and Drug Administration, Scott Gottlieb, announced a federal crackdown on e-cigarettes. He had seen the data on soaring use among teen-agers, and, he said, “it shocked my conscience.” He announced that the F.D.A. would ban many kinds of flavored e-cigarettes, which are especially popular with teens, and would restrict the retail outlets where e-cigarettes were available.
Cannabis use and psychotic symptoms and disorders are associated in the general population (see, for example, Degenhardt and Hall, 2001; Tien and Anthony, 1990) and in clinical samples of patients with schizophrenia (Mueser et al., 1992; Warner et al., 1994; Hambrecht and Hafner, 1996). The major contending hypotheses to explain the association have been: (i) that cannabis use precipitates schizophrenia in persons who are otherwise vulnerable; (ii) cannabis use is a form of self-medication for schizophrenia; and (iii) that the association arises from uncontrolled residual confounding by variables that predict an increased risk of cannabis use and of schizophrenia (Macleod et al., 2004).
The seeds are sown with grain drills or other conventional seeding equipment to a depth of 1.27 to 2.54 cm. Greater seeding depths result in increased weed competition. Nitrogen should not be placed with the seed, but phosphate may be tolerated. The soil should have available 89 to 135 kg/ha of nitrogen, 46 kg/ha phosphorus, 67 kg/ha potassium, and 17 kg/ha sulfur. Organic fertilizers such as manure are one of the best methods of weed control.
Cannabis is predominantly dioecious, having imperfect flowers, with staminate "male" and pistillate "female" flowers occurring on separate plants. "At a very early period the Chinese recognized the Cannabis plant as dioecious", and the (c. 3rd century BCE) Erya dictionary defined xi 枲 "male Cannabis" and fu 莩 (or ju 苴) "female Cannabis". Male flowers are normally borne on loose panicles, and female flowers are borne on racemes.
Dehulled (i.e. hulled) hemp seed is a very recent phenomenon, first produced in quantity in Europe. Hemp seeds have been used as food since ancient times, but generally the whole seed, including the hull, was eaten. Hemp seed was a grain used in ancient China, although there has been only minor direct use of hemp seed as food by humans. In the past, hemp seed has generally been a food of the lower classes, or a famine food. Peanut-butter type preparations have been produced from hemp seed in Europe for centuries, but were rather gritty since technology for removing the hulls was rudimentary. Modern seed dehulling using mechanical separation produces a smooth, white, gritless hemp seed meal that needs no additional treatment before it is consumed. It is important to understand, therefore, that the quality of modern hemp seed for human consumption far exceeds anything produced historically. This seed meal should be distinguished from the protein-rich, oil-poor seed cake remaining after oil has been expressed, that is used for livestock feed. The seed cake is also referred to as “seed meal,” and has proven to be excellent for animals (Mustafa et al. 1999).
While marijuana cultivation requires ample spacing to reduce the risk of mold or bacteria, hemp can be planted more densely. Most marijuana crops are planted at one (1) plant per four (4) square feet. Hemp plants that are grown for hemp oil are planted at roughly 40 to 60 plants per four (4) square feet. Hemp plants grown for fiber are even more densely planted at a rate of about 100 to 120 plants per four (4) square feet.
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.
The regular followers of this blog would know that I suffer from back pain and sleep disorders. So, before I test out CBD products, I give myself a break from CBD to see how the product affects me fully. Fab CBD sells, 4 versions of the CBD Oil with 150mg, 300mg, 600mg and 1200mg. For people who like flavors with their oils, there are different flavors available too.
"Approximately 30 countries in Europe, Asia, and North and South America currently permit farmers to grow hemp. Some of these countries never outlawed production, while some countries banned production for certain periods in the past. China is among the largest producing and exporting countries of hemp textiles and related products, as well as a major supplier of these products to the United States. The European Union (EU) has an active hemp market, with production in most member nations. Production is centered in France, the United Kingdom, Romania, and Hungary.30

Also high in fiber, hemp seeds are more digestible than any other high-protein food, including meat, cheese, eggs, human milk, or cows’ milk. They’re high in antioxidants, and minerals like iron, zinc and copper as well as calcium, magnesium, potassium, carotene, thiamin (vitamin B1), riboflavin (vitamin B2), vitamin B6 and vitamin E. If that’s not enough, there’s also chlorophyll, sulfur, phosphorus, phospholipids, and phytosterols.
There are two possible exceptions to this. The first is that some people, for unknown reasons, just react differently to CBD. According to Dr. Chin, about 5% of people say they feel altered after taking CBD. "Usually they're the same people who have side effects from Advil or Tylenol," she says. You never know how your body will react to any new supplement, so when taking CBD for the first time, do so safely under supervision.
Scientists in Europe and North America concluded that hemp seed is an excellent source of nutrition. Numerous anecdotal incidences cited improvements in a wide range of acute and chronic conditions such as rapid healing of skin lesions and relief from flu, inflammation, and allergies. The benefits were attributed to the presence of rich source of the EFAs linoleic and alpha-linolenic acid, and their respective biologic metabolites, GLA and stearidonic acid.9
The edible seeds contain about 30 percent oil and are a source of protein, fibre, and magnesium. Shelled hemp seeds, sometimes called hemp hearts, are sold as a health food and may be eaten raw; they are commonly sprinkled on salads or blended with fruit smoothies. Hemp seed milk is used as an alternative to dairy milk in drinks and recipes. The oil obtained from hemp seed can be used to make paints, varnishes, soaps, and edible oil with a low smoke point. Historically, the seed’s chief commercial use has been for caged-bird feed.
Medical marijuana refers to the use of the Cannabis plant as a physician-recommended herbal therapy as well as synthetic THC and cannabinoids. So far, the medical use of cannabis is legal only in a limited number of territories, including Canada, Belgium, Australia, the Netherlands, Spain, and many U.S. states. This usage generally requires a prescription, and distribution is usually done within a framework defined by local laws. There is evidence supporting the use of cannabis or its derivatives in the treatment of chemotherapy-induced nausea and vomiting, neuropathic pain, and multiple sclerosis. Lower levels of evidence support its use for AIDS wasting syndrome, epilepsy, rheumatoid arthritis, and glaucoma.
Chronic pain: The body’s ECS plays a role in alleviating and managing pain, so CBD oil can work as a supplement for individuals with medical conditions that cause chronic pain, such as arthritis and multiple sclerosis. CBD oil also increases levels of adenosine in the brain; adenosine is a neurotransmitter that aids cardiovascular function and eases painful inflammation.
As one of the original CBD manufacturers, Green Roads reputation truly precedes them, and their pharmacist formulated manufacturing process is why we selected them as the best quality CBD oil on the market. They offer a range of CBD oil concentrations (100mg, 250mg, 350mg, 550mg, 1000mg, 1500mg, and 3,500mg) all of which allow you to view ingredients and test results from a 3rd party testing facility via a QR code on the box.
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).
In a study with HIV-positive adult men, blood concentrations of ghrelin and other appetitive hormones (leptin, PYY, and insulin) were tested after having received smoked medicinal cannabis or matched placebo for HIV-associated neuropathic pain. Cannabis administration, as compared to placebo, significantly increased ghrelin concentrations in this study. In addition, leptin and PYY levels were, respectively, increased and decreased, but no impact on insulin levels was found (Riggs et al., 2012).
Karl W. Hillig, a graduate student in the laboratory of long-time Cannabis researcher Paul G. Mahlberg at Indiana University, conducted a systematic investigation of genetic, morphological, and chemotaxonomic variation among 157 Cannabis accessions of known geographic origin, including fiber, drug, and feral populations. In 2004, Hillig and Mahlberg published a chemotaxonomic analysis of cannabinoid variation in their Cannabis germplasm collection. They used gas chromatography to determine cannabinoid content and to infer allele frequencies of the gene that controls CBD and THC production within the studied populations, and concluded that the patterns of cannabinoid variation support recognition of C. sativa and C. indica as separate species, but not C. ruderalis. The authors assigned fiber/seed landraces and feral populations from Europe, Central Asia, and Turkey to C. sativa. Narrow-leaflet and wide-leaflet drug accessions, southern and eastern Asian hemp accessions, and feral Himalayan populations were assigned to C. indica. In 2005, Hillig published a genetic analysis of the same set of accessions (this paper was the first in the series, but was delayed in publication), and proposed a three-species classification, recognizing C. sativa, C. indica, and (tentatively) C. ruderalis. In his doctoral dissertation published the same year, Hillig stated that principal components analysis of phenotypic (morphological) traits failed to differentiate the putative species, but that canonical variates analysis resulted in a high degree of discrimination of the putative species and infraspecific taxa. Another paper in the series on chemotaxonomic variation in the terpenoid content of the essential oil of Cannabis revealed that several wide-leaflet drug strains in the collection had relatively high levels of certain sesquiterpene alcohols, including guaiol and isomers of eudesmol, that set them apart from the other putative taxa. Hillig concluded that the patterns of genetic, morphological, and chemotaxonomic variation support recognition of C. sativa and C. indica as separate species. He also concluded there is little support to treat C. ruderalis as a separate species from C. sativa at this time, but more research on wild and weedy populations is needed because they were underrepresented in their collection.
Most human studies of CBD have been done on people who have seizures, and the FDA recently approved the first CBD-based drug, Epidiolex, for rare forms of epilepsy. Clinical trials for other conditions are promising, but tiny. In one Brazilian study published in 2011 of people with generalized social anxiety disorder, for example, taking a 600-mg dose of CBD (higher than a typical dose from a tincture) lessened discomfort more than a placebo, but only a dozen people were given the pill.
Because hemp-derived CBD currently lacks labeling and purity standards that are required of cannabis products sold at legal dispensaries, it exists in a regulatory limbo that laws don’t yet address. In the meantime, the Los Angeles County Department of Public Health has announced that starting in July, putting CBD in food products will cost businesses points on their health inspections.
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. 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.
