The question of whether heteromorphic sex chromosomes are indeed present is most conveniently answered if such chromosomes were clearly visible in a karyotype. Cannabis was one of the first plant species to be karyotyped; however, this was in a period when karyotype preparation was primitive by modern standards (see History of Cytogenetics). Heteromorphic sex chromosomes were reported to occur in staminate individuals of dioecious "Kentucky" hemp, but were not found in pistillate individuals of the same variety. Dioecious "Kentucky" hemp was assumed to use an XY mechanism. Heterosomes were not observed in analyzed individuals of monoecious "Kentucky" hemp, nor in an unidentified German cultivar. These varieties were assumed to have sex chromosome composition XX.[31] According to other researchers, no modern karyotype of Cannabis had been published as of 1996.[32] Proponents of the XY system state that Y chromosome is slightly larger than the X, but difficult to differentiate cytologically.[33]

But there’s a big difference between the two. Hemp seed oil has been pressed from hemp seed, and it’s great for a lot of things – it’s good for you, tastes great, and can be used in soap, paint – even as biodiesel fuel. However, hemp seed oil does not contain any concentration of cannabinoids at all, including CBD. So by all means, stock up at your local natural food store. Just don’t expect to reap the benefits of a true CBD oil when you cook with hemp seed oil.
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.
Hi Colleen, it's almost a year later and I'm wondering how you're doing. I'm experiencing a recurrence of Stage 3 ovarian, originally diagnosed in 2011. I've decided to get some chemo, not sold on another 6 cycles though. As a new MMJ patient, I'm still going to go through with Rick Simpson Oil (THC+CBD,) and I just joined a program with my local dispensary to get CBD capsules for $2 each when I order them at least 30 at a time. I hope you're doing well!! I'm off to do more research on dosing. **NOTE: If you have ANY experience with CBD treatment of ovarian cancer, PLEASE respond. Thank you!!
Hemp’s greatest obstacle is its association with psychoactive cannabis, despite the important distinction that hemp contains only nominal amounts (no more than 0.3%) of the psychoactive ingredient, tetrahydrocannabinol (THC). Although the U.S. is the largest importer of hemp products according to the Hemp Business Journal (a New Frontier Data subsidiary), hemp itself has struggled to gain social acceptance in the country and elsewhere. For instance, current U.S. legislation only permits universities and states performing agricultural or academic research to cultivate hemp. However, the 2018 Farm Bill currently in Congress would grant hemp full legalization across the nation. Passage of this bill would be a key step in promoting public acceptance in the U.S. and elsewhere, allowing the country to participate in the rapidly growing global hemp market.
The use of Cannabis for seed oil (Fig. 36) began at least 3 millennia ago. Hempseed oil is a drying oil, formerly used in paints and varnishes and in the manufacture of soap. Present cultivation of oilseed hemp is not competitive with linseed for production of oil for manufacturing, or to sunflower and canola for edible vegetable oil. However, as noted below, there are remarkable dietary advantages to hempseed oil, which accordingly has good potential for penetrating the salad oil market, and for use in a very wide variety of food products. There is also good potential for hemp oil in cosmetics and skin-care products.
Can CBD oil help anxiety? Cannabidiol (CBD) is a chemical occurring in cannabis plants. It is possible to add CBD oil to food, and an increasing amount of evidence suggests that it may improve mental health, particularly anxiety. It does not seem to have adverse side effects, but CBD oil is illegal in some states. Learn more about CBD oil here. Read now
In November 2015, Uttarakhand became the first state of India to legalize the cultivation of hemp for industrial purposes.[223] 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.[224] 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.[224]
Cannabis is frequently used among Sufis[131] – the mystical interpretation of Islam that exerts strong influence over local Muslim practices in Bangladesh, India, Indonesia, Turkey, and Pakistan. Cannabis preparations are frequently used at Sufi festivals in those countries.[131] Pakistan's Shrine of Lal Shahbaz Qalandar in Sindh province is particularly renowned for the widespread use of cannabis at the shrine's celebrations, especially its annual Urs festival and Thursday evening dhamaal sessions - or meditative dancing sessions.[132][133]
Down the line, Johnson also plans to create an onsite grow-space in the large two-story building where he's set up shop. In addition to getting deep satisfaction from the relief that customers say his CBD products provide, Johnson remains enthralled with "the fun side" of hemp production: namely, planting a seed and letting it grow. "It's just like in life," he added. "I can't say enough about the process, about the feeling of actually producing something."
Given the uncertainties and handicaps associated with hemp, it is fortunate that there are compensating factors. As noted, as a crop hemp offers some real environmental advantages, particularly with regard to the limited needs for herbicides and pesticides. Hemp is therefore pre-adapted to organic agriculture, and accordingly to the growing market for products associated with environmentally-friendly, sustainable production. Hemp products are an advertiser’s dream, lending themselves to hyperbole (“healthiest salad oil in the world,” “toughest jeans on the market”). While the narcotics image of C. sativa is often disadvantageous, advertisers who choose to play up this association do so knowing that it will attract a segment of the consuming population. In general, the novelty of hemp means that many consumers are willing to pay a premium price. It might also be said that those who have entered the hemp industry have tended to be very highly motivated, resourceful, and industrious, qualities that have been needed in the face of rather formidable obstacles to progress.
CDFA has not yet proposed any regulations regarding industrial hemp. Regulations pertaining to cultivation will be developed in conjunction with the Industrial Hemp Advisory Board, and will be promulgated through the regular rulemaking process in accordance with the California Administrative Procedures Act. CDFA will notify the public via our electronic mailing list as regulations are posted and available for public comment.

It often takes 10 to 15 years for the industry associated with a new agricultural crop to mature. While it is true that foreign imports have been the basis for hemp products in North America for at least a decade, North American production is only 4 years of age in Canada, and farming of hemp in the US has not even begun. Viewed from this perspective, the hemp industry in North America is still very much in its infancy. Varieties of hemp specifically suited to given products and regions have only started to be developed in North America. There is considerable uncertainty regarding yields, costs of production, harvesting and processing equipment, product characteristics, foreign competition, governmental support, and the vagaries of the regulatory environment. Hemp is not presently a standard crop, and is likely to continue experiencing the risks inherent in a small niche market for some time. Hemp is currently a most uncertain crop, but has such a diversity of possible uses, is being promoted by extremely enthusiastic market developers, and attracts so much attention that it is likely to carve out a much larger share of the North American marketplace than its detractors are willing to concede.

CBD is a 5-HT1A receptor agonist, which may also contribute to an anxiolytic effect.[146] This likely means the high concentrations of CBD found in Cannabis indica mitigate the anxiogenic effect of THC significantly.[146] The cannabis industry claims that sativa strains provide a more stimulating psychoactive high while indica strains are more sedating with a body high.[147] However this is disputed by researchers.[148]

But all was not well. Harper has continued to experience health issues related to her condition. And seven months after starting to use CBD oil, Harper’s seizures returned— although not as frequently as before. Penny uses eleven iPhone reminders to keep track of Harper’s daily regimen of medications and food, and she records all of Harper’s seizures in a thickly bound black book. But as her parents continue to closely monitor Harper’s health and adjust her medications accordingly, her doctors are tightly limited in the advice they can offer when it comes to CBD oil. “There’s no research on this product, so they don’t say it’s good or bad. They just say, ‘Don’t stop giving it,’” Penny told me.

One of the reasons hemp fiber has been valued is because of its length. The primary bast fibers in the bark are 5–40 mm long, and are amalgamated in fiber bundles which can be 1–5 m long (secondary bast fibers are about 2 mm long). The woody core fibers are short—about 0.55 mm—and like hardwood fibers are cemented together with considerable lignin. The core fibers are generally considered too short for high grade paper applications (a length of 3 mm is considered ideal), and too much lignin is present. While the long bast fibers have been used to make paper almost for 2 millennia, the woody core fibers have rarely been so used. Nevertheless it has been suggested that the core fibers could be used for paper making, providing appropriate technology was developed (de Groot et al. 1998). In any event, the core fibers, have found a variety of uses, as detailed below. The long, lignin-poor bast fibers also have considerable potential to be used in many non-paper, non-textile applications, as noted below.
CatryNA49; Cannabis, like Opium poppies, and the substances derived from these plants, were also made illegal as a means of preventing white females, from being seduced, and or raped by male members of minority races; seriously ! In the early 70s Nixon administration officials oversaw the expansion of drug laws, as a means of legally repressing the two groups of Americans, that administration deemed to be their biggest foes; those groups being, African Americans, and the antiwar left. We know the drug war, just like the earlier less repressive drug laws, was initiated as a means of legal political, and racial repression because of the fact that a Nixon adm. official is on film, admitting as much. You can Google that film if you like. Now despite the truth about the drug war being admitted on film, for anyone in the world who has internet access can see, the drug war continues to be waged by politicians; the same politicians by the way, that tens of millions of Americans continue to vote for. I should add, that in the last presidential election, the candidate who promised to refuel the drug war, was the candidate who won that election. Of course what else could you expect, being that we live in the land of the free and the home of the brave ?!
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.

"The data supporting efficacy and dosing are specific to one product: Epidiolex," Bonn-Miller says. "That's not necessarily translatable to 'Joe Bob's CBD Blend.'" A CBD extract you buy online or in a dispensary will almost certainly have less CBD in it, he explains, and will contain other cannabinoids—meaning that it will work differently and will need to be dosed differently. "This is not to say that 'Joe Bob's CBD Blend' definitely isn't going to be effective for pediatric epilepsy, but it means that we need to study it before we know."
Use of industrial hemp plant and its cultivation was commonplace until the 1900s, when it was associated with its genetic sibling aka Drug-Type Cannabis species (which contain higher levels of psychoactive THC). Influential groups misconstrued hemp as a dangerous 'drug', even though it is not a 'drug' and it has the potential to be a sustainable & profitable alternative crop.

A 2012 review found that the THC content in marijuana had increased worldwide from 1970 to 2009.[150] It is unclear, however, whether the increase in THC content has caused people to consume more THC or if users adjust based on the potency of the cannabis. It is likely that the higher THC content allows people to ingest less tar. At the same time, CBD levels in seized samples have lowered, in part because of the desire to produce higher THC levels and because more illegal growers cultivate indoors using artificial lights. This helps avoid detection but reduces the CBD production of the plant.[151]

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.
Taking CBD oil is like drinking milk and calling it calcium, Hernandez said: There’s some in there, but at very low concentrations dispersed among a host of other ingredients. And what those other ingredients are is anyone’s guess. “The thing to know is that CBD hasn’t gone through the safety controls, the efficacy controls that we usually use, the clinical trials,” Hernandez said. “The jury is still out regarding how safe this drug is.”
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.
