In the meantime, some physicians are forging ahead — and cashing in. Joe Cohen is a doctor at Holos Health, a medical marijuana clinic in Boulder. I asked him what CBD is good for, and he read me a long list of conditions: pain, inflammation, nausea, vomiting, intestinal cramping, anxiety, psychosis, muscle spasms, hyperactive immune systems, nervous system degeneration, elevated blood sugar and more. He also claimed that CBD has anti-cancer properties and can regenerate brain cells and reduce the brain’s levels of amyloid beta — a kind of protein that’s been linked to Alzheimer’s disease. I asked for references, noting that most of these weren’t listed in the Academies report or a similar review published in the Journal of the American Medical Association. “I think you just have to Google search it,” he said. It’s true that a preliminary study found hints that cannabinoids might reduce beta amyloid proteins in human brain cells, but the study was done in cells grown in a lab, not in people. As for cancer, the FDA sent warning letters last year to four companies that were selling products that claimed to “prevent, diagnose, treat or cure” cancer.
The high absorbency of hemp hurds has led to their occasional use as an absorbent for oil and waste spill cleanup. Hemp as an industrial absorbent has generated some interest in Alberta, for use in land reclamation in the oil and gas industry. Because hemp hurds are a costly product, it is likely that animal bedding will remain the most important application.
In 1972, the Dutch government divided drugs into more- and less-dangerous categories, with cannabis being in the lesser category. Accordingly, possession of 30 grams or less was made a misdemeanor. Cannabis has been available for recreational use in coffee shops since 1976. Cannabis products are only sold openly in certain local "coffeeshops" and possession of up to 5 grams for personal use is decriminalised, however: the police may still confiscate it, which often happens in car checks near the border. Other types of sales and transportation are not permitted, although the general approach toward cannabis was lenient even before official decriminalisation.
To whom my comment is relevant: I have bipolar type 2, so my mood will cycle from major depression to “feeling well” in periods lasting about a week. CBD oil, taken orally as a spray, only seems to help if I am experiencing anxiety while in my “normal” mood. While intensely suffering, vaporizing marijuana offers a moderately helpful, temporary relief. I still cannot do my math or physics homework after using marijuana, but I can’t do much of anything besides exist while severely depressed/anxious, so I am grateful to live in a time and place where access to marijuana is safe and readily available.
The objectivity of scientific evaluation of the medicinal value of marijuana to date has been questioned. In the words of Hirst et al. (1998): “The ...status of cannabis has made modern clinical research almost impossible. This is primarily because of the legal, ethical and bureaucratic difficulties in conducting trials with patients. Additionally, the general attitude towards cannabis, in which it is seen only as a drug of abuse and addiction, has not helped.” In a recent editorial, the respected journal Nature (2001) stated: “Governments, including the US federal government, have until recently refused to sanction the medical use of marijuana, and have also done what they can to prevent its clinical testing. They have defended their inaction by claiming that either step would signal to the public a softening of the so-called ‘war on drugs.’... The pharmacology of cannabinoids is a valid field of scientific investigation. Pharmacologists have the tools and the methodologies to realize its considerable potential, provided the political climate permits them to do so.” Given these current demands for research on medicinal marijuana, it will be necessary to produce crops of drug types of C. sativa.
“The plan? Whip the public into a frenzy over ill effects of marijuana, the psychoactive leaves and flowers of the hemp plant; the reputation of the fibers and seeds used by industry would be posing little threat to society emerged as the ‘assassin of youth.’ The strategy worked. In 1937, with virtually no warning, Congress announced a prohibitive tax on hemp, effectively ending the production and sale of the plant in the United States.
Industrial hemp contains, by weight, far less CBD than CBD-rich cultivars such as Harlequin or Sour Tsunami. This means that producing a single 10 mL dose of CBD would require the cultivation and extraction of far more hemp than it would from whole-plant marijuana; thus raising the risk of exposing users to more contaminants. Hemp is classified as a “bioaccumulator,” or a plant that naturally absorbs toxicants from the soil.
Until recent times, the cultivation of hemp primarily as an oilseed was largely unknown, except in Russia. Today, it is difficult to reconstruct the type of plant that was grown there as an oilseed, because such cultivation has essentially been abandoned. Oilseed hemp cultivars in the modern sense were not available until very recently, but some land races certainly were grown specifically for seeds in Russia. Dewey (1914) gave the following information: “The short oil-seed hemp with slender stems, about 30 inches high, bearing compact clusters of seeds and maturing in 60 to 90 days, is of little value for fiber production, but the experimental plants, grown from seed imported from Russia, indicate that it may be valuable as an oil-seed crop to be harvested and threshed in the same manner as oil-seed flax.” Most hemp oilseed in Europe is currently obtained from so-called “dual usage” plants (employed for harvest of both stem fiber and seeds, from the same plants). Of the European dual-usage cultivars, ‘Uniko B’ and ‘Fasamo’ are particularly suited to being grown as oilseeds. Very recently, cultivars have been bred specifically for oilseed production. These include ‘Finola,’ formerly known as ‘Fin-314’ (Fig. 6) and ‘Anka’ (Fig. 7), which are relatively short, little-branched, mature early in north-temperate regions, and are ideal for high-density planting and harvest with conventional equipment. Dewey (1914) noted that a Turkish narcotic type of land race called “Smyrna” was commonly used in the early 20th century in the US to produce birdseed, because (like most narcotic types of Cannabis) it is densely branched, producing many flowers, hence seeds. While oilseed land races in northern Russia would have been short, early-maturing plants in view of the short growing season, in more southern areas oilseed landraces likely had moderate height, and were spaced more widely to allow abundant branching and seed production to develop. Until Canada replaced China in 1998 as a source of imported seeds for the US, most seeds used for various purposes in the US were sterilized and imported from China. Indeed, China remains the largest producer of hempseed. We have grown Chinese hemp land races, and these were short, branched, adapted to a very long growing season (i.e. they come into flower very slowly in response to photoperiodic induction of short days in the fall), and altogether they were rather reminiscent of Dewey’s description of Smyrna. Although similar in appearance to narcotic strains of C. sativa, the Chinese land races we grew were in fact low in intoxicating constituents, and it may well be that what Dewey thought was a narcotic strain was not. Although some forms of C. sativa have quite large seeds, until recently oilseed forms appear to have been mainly selected for a heavy yield of seeds, usually recognizable by abundant branching. Such forms are typically grown at lower densities than hemp grown only for fiber, as this promotes branching, although it should be understood that the genetic propensity for branching has been selected. Percentage or quality of oil in the seeds does not appear to have been important in the past, although selection for these traits is now being conducted. Most significantly, modern selection is occurring with regard to mechanized harvesting, particularly the ability to grow in high density as single-headed stalks with very short branches bearing considerable seed.
The most widespread claim for environmental friendliness of hemp is that it has the potential to save trees that otherwise would be harvested for production of lumber and pulp. Earlier, the limitations of hemp as a pulp substitute were examined. With respect to wood products, several factors appear to favor increased use of wood substitutes, especially agricultural fibers such as hemp. Deforestation, particularly the destruction of old growth forests, and the world’s decreasing supply of wild timber resources are today major ecological concerns. Agroforestry using tree species is one useful response, but nevertheless sacrifices wild lands and biodiversity, and is less preferable than sustainable wildland forestry. The use of agricultural residues (e.g. straw bales in house construction) is an especially environmentally friendly solution to sparing trees, but material limitations restrict use. Another chief advantage of several annual fiber crops over forestry crops is relative productivity, annual fiber crops sometimes producing of the order of four times as much per unit of land. Still another important advantage is the precise control over production quantities and schedule that is possible with annual crops. In many parts of the world, tree crops are simply not a viable alternative. “By the turn of the century 3 billion people may live in areas where wood is cut faster than it grows or where fuelwood is extremely scarce” (World Commission on Environment and Development 1987). “Since mid-century, lumber use has tripled, paper use has increased six-fold, and firewood use has soared as Third World populations have multiplied” (Brown et al. 1998). Insofar as hemp reduces the need to harvest trees for building materials or other products, its use as a wood substitute will tend to contribute to preserving biodiversity. Hemp may also enhance forestry management by responding to short-term fiber demand while trees reach their ideal maturation. In developing countries where fuelwood is becoming increasingly scarce and food security is a concern, the introduction of a dual-purpose crop such as hemp to meet food, shelter, and fuel needs may contribute significantly to preserving biodiversity.
There is reasonable evidence from prospective epidemiological studies which suggests that cannabis use can precipitate schizophrenia in persons who are vulnerable because of a personal or family history of schizophrenia. There is also evidence that a genetic vulnerability to psychosis increases the risk that cannabis users will develop psychosis (McGuire et al., 1995; Arseneault et al., 2002; Verdoux et al., 2002). A casual relationship also has biological plausibility in that the cannabinoid and dopaminergic neurotransmitter systems interact in animals. D'Souza and colleagues (1999) have shown in a provocation study that THC produces a dose-dependent increase in psychotic symptoms under double-blind placebo conditions; and Caspi and colleagues (2005) have shown an interaction between specific alleles of the COMT allele and psychotogenic effects of cannabis. If these results can be replicated and extended, they will increase the likelihood that cannabis can be a contributory cause of psychosis in vulnerable individuals.
A recent study published in The International Journal of Neurophamacologypoints to cannabidiol (CBD) as a cause of neurogenesis in the brain; specifically in the Hippocampus, an area typically associated with conscious memory and navigation. However, the researchers believe that CBD’s anxiety relief may be due to this neurogenesis in the brain. You can read our full article on the study here.

Fibres are obtained by subjecting the stalks to a series of operations—including retting, drying, and crushing—and a shaking process that completes separation from the woody portion, releasing the long, fairly straight fibre, or line. The fibre strands, usually over 1.8 metres (5.8 feet) long, are made of individual cylindrical cells with an irregular surface. The fibre, longer and less flexible than flax, is usually yellowish, greenish, or a dark brown or gray and, because it is not easily bleached to sufficiently light shades, is rarely dyed. It is strong and durable and is used for cordage—e.g., twine, yarn, rope, cable, and string—and for artificial sponges and such coarse fabrics as sacking (burlap) and canvas. In Italy some hemp receives special processing, producing whitish colour and attractive lustre, and is used to make fabric similar to linen.

The psychoactive effects of cannabis are known to have a triphasic nature. Primary psychoactive effects include a state of relaxation, and to a lesser degree, euphoria from its main psychoactive compound, tetrahydrocannabinol. Secondary psychoactive effects, such as a facility for philosophical thinking, introspection and metacognition have been reported among cases of anxiety and paranoia. Finally, the tertiary psychoactive effects of the drug cannabis, can include an increase in heart rate and hunger, believed to be caused by 11-OH-THC, a psychoactive metabolite of THC produced in the liver.
Deeper pockets are also helping them to dominate CBD products—derived from cannabis but without a high—that are of interest to some of the world’s biggest consumer companies, including... — Carol Ryan, WSJ, "U.S. Cannabis Law Is Helping Canada Make Hay," 27 Feb. 2019 Meanwhile, 10 states and Washington, DC, have legalized the intoxicating form of cannabis for recreational purposes, while 32 states have for medical uses. — German Lopez, Vox, "Trump and Congress just legalized hemp," 20 Dec. 2018 The state’s Cannabis Control Commission has since granted one dispensary a provisional retail license, and another company licenses to grow and transport non-medical cannabis. — Matthew Ormseth, courant.com, "U.S. Attorney in Massachusetts Says Opioids, Not Marijuana, A Priority As State Readies Retail Market," 10 July 2018 The city's mayor Alex Morse believes Holyoke is the ideal location for the cannabis industry in Massachusetts -- and possibly the country. — CBS News, "Holyoke, Massachusetts, is ready to welcome the marijuana industry with open arms," 30 June 2018 Rat offspring exposed to THC — tetrahydrocannabinol, the chief psychoactive ingredient in cannabis — and others that were not had to learn how to press one of two levers to get a sugar pellet reward. — Erik Lacitis, The Seattle Times, "‘Something wasn’t clicking’: WSU study shows offspring of pregnant rats exposed to THC have impaired development," 20 Nov. 2018 It's also derived from cannabidiol (CBD), one of the major compounds found in cannabis. — Sarah Jacoby, SELF, "Updated: What You Need to Know About Epidiolex, the First FDA-Approved Drug Made From Cannabis," 1 Nov. 2018 Attendees must bring their own cannabis, but smoking, edibles, and vaping are all encouraged as part of the creative process and the social experience. — Sarah Shemkus, BostonGlobe.com, "5 marijuana-infused things to do in New England," 21 June 2018 But Salmonella can also turn up in unexpected places — like in tahini, or on cantaloupes, or even drugs like cannabis and kratom. — Rachel Becker, The Verge, "Machine learning could help figure out what pooped on your produce," 12 Dec. 2018
When I first learned about CBD oil, I'll admit I was a bit skeptical. My mind immediately turned to weed and the unnerving experiences I'd had with heightened anxiety in college. For me, a person who's already predisposed to overthinking, marijuana, no matter what the form, would typically put my mind into overdrive and result in a common yet dreaded side effect: paranoia.

Cannabis impairs psychomotor performance in a wide variety of tasks, such as motor coordination, divided attention, and operative tasks of many types; human performance on complex machinery can be impaired for as long as 24 hours after smoking as little as 20 mg of THC in cannabis; there is an increased risk of motor vehicle accidents among persons who drive when intoxicated by cannabis.
When seizures in K9s are diagnosed, many vets put them on strong pharmacological medications like potassium bromide or phenobarbital to combat the condition. However, those drugs come with some serious side effects, including damage to their liver and other vital organs, lethargy, confusion, and dizziness, and more. Even with these debilitating side effects, these medications aren’t always effective in treating dog seizures.

Neuroscience and Biobehavioral Reviews. 88: 26–41. doi:10.1016/j.neubiorev.2018.03.008. PMID 29535069. This may reflect the multitude of cognitive tasks employed by the various studies included in these meta-analyses, all of which involved performing a task thereby requiring the participant to reorient their attention and attempt to solve the problem at hand and suggest that greater engagement of this region indicates less efficient cognitive performance in cannabis users in general, irrespective of their age.
Both CBD oil and cream have shown to have powerful effects on alleviating pain. They each have their own unique benefits and can both be used to relieve pain, regardless of what the source of the pain may be. Ultimately, the choice between which format to use will depend on the users' specific preferences, as they are both highly effective in reducing pain and many other discomforts.
Document It: Keep a journal of your dog before and for several days if you decide to use a CBD product. This will help you decide whether it’s having a positive effect. Better still, record video of your dog to document their progress, or lack thereof (this will help you overcome the flaws of human memory). Or ask your friends/family whether they’ve noticed any difference in your dog without telling them that you’ve been giving your dog CBD (the closest you’ll get to a blinded study).

Another concern is about medications with which CBD might interact. This won’t be an issue with most drugs, says Sunil Kumar Aggarwal, M.D., Ph.D., a palliative medicine physician and scientist who studies cannabis and integrates it into his Seattle medical practice. The exceptions are blood thinners, IV antibiotics, and other drugs whose exact dosing is crucial and must be monitored closely, he says. (Of course, if you have a health problem, talk to your doctor before using CBD, and never take it instead of seeing your physician for a serious condition.)
As of November 2016, 33 states and the District of Columbia legally allow cannabis for personal medical use. Rules surrounding the use of medical cannabis (medical marijuana) vary by state. The first state in the union to legalize the medical use of marijuana was California in 1996. States that allow medical marijuana include: Alaska, Arizona, Arkansas, California, Colorado, Connecticut, Delaware, Florida, Hawaii, Illinois, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, Montana, Nevada, New Hampshire, New Jersey, New Mexico, North Dakota, New York, Ohio, Oregon, Pennsylvania, Rhode Island, Utah, Vermont, Washington, and the District of Columbia. It is important to recognize that these state marijuana laws do not change the fact that using marijuana continues to be an offense under Federal law.
I discovered in my research that hemp is really legal in all 50 states so I guess this must be a very complicated thing. It may be likely some states are allowed to grow it and others aren’t, I don’t know but all I know is somewhere in my research it said it was legal in all 50 states. Anyway, I got my oil on auto delivery, I really need to start using it in my food a little more often to help with certain health issues including but not limited to arthritis pain 😇👍
Due to the influence of big pharma,the FDA has refused (until recently) to investigate the benefits of phytocannabinoid oil for humans or pets. We are not allowed to say or imply that phytocannabinoid has any medical benefits, however the 1st Amendment also protects our right to tell you about our experiences with phytocannabinoid helping our own pets, and the fact that there have been more than 1500 clinical studies regarding the effectiveness of phytocannabinoids.*The owners and staff of Innovet believe, but cannot legally claim or imply, that countless dogs and cats have used phytocannabinoid oils for many conditions.
Several studies have demonstrated the therapeutic effects of cannabinoids for nausea and vomiting in the advanced stages of illnesses such as cancer and AIDS. Dronabinol (tetrahydrocannabinol) has been available by prescription for more than a decade in the USA. Other therapeutic uses of cannabinoids are being demonstrated by controlled studies, including treatment of asthma and glaucoma, as an antidepressant, appetite stimulant, anticonvulsant and anti-spasmodic, research in this area should continue. For example, more basic research on the central and peripheral mechanisms of the effects of cannabinoids on gastrointestinal function may improve the ability to alleviate nausea and emesis. More research is needed on the basic neuropharmacology of THC and other cannabinoids so that better therapeutic agents can be found.
I had a dog with lymphoma that was extremely aggressive…she was 12 when she was diagnosed, but was an active breed, and it too, started in her mammary glands, and I noticed it very early. She was extremely active/athletic – we decided due to her age, we gave her an amazing life, she was the dog of a lifetime and was just amazing (we rescued her a year old from a pet rescue that was going out of business – whatever wasn’t adopted was going to whatever shelters in the state that had room – they were no kill – the others that they were sending to weren’t all no kill….she was the only dog left….she was with another couple, they decided not to get her and handed my husband the leash. We were discussing it – it was 5 minutes before they were closing the doors for the last time, and she laid down at his feet. I told him it was up to him, but if he wasn’t going to do it, he had to take her in bc I simply couldn’t do it. He said “ok then, tell her bye bc we don’t know what will happen”…he reached for the door, swung it open and yelled “she’s coming with us and no one else!”), anyhow (sorry, lol), we decided not to treat the cancer and make her more sick, put off the inevitable….but to treat her symptoms and keep her comfortable. We started with a round of antibiotics while she was still strong (you never would’ve known anything was going on. I found 2 bilateral small mammary lumps when she was completely stretched on her back and I was rubbing her belly – she was all muscle – not a single ounce of fat – so they were very noticeable to me), as a prophylactic treatment for 2 weeks, then high dose steroids for 2 weeks (which can lower the white blood cell count and make them prone to infection, hence the antibiotics prior), then maintenance steroids to slow the growth. She remain EXTREMELY active through it all. About 2 months later, I guess she kinda hit a rough patch and everything grew…all of her mammary glands became huge to where when she tried to jump on things, to stomach was to tight and stretched, she was in pain and would miss, so she would really eye it, rock back and forth and put a lot of effort if she wasn’t patient enough for us to help her. Our vet put her on Gabapentin and increased the steroids, which slowed everything and helped her pain. Then her lymphnodes completely took off…under her front legs, around her neck…but she still remain active, eating and no change in pain, as if nothing was wrong. We were able to keep her comfortable a total of 5 months until it began wearing on her, then she began having cardiac changes and distancing herself from us for 3 days (both together, I’m a paramedic, I noticed she was staying into congestive heart failure), so we took her to end her pain. The point of all of this, and I’m sorry it took so long to get there….is that I wish that there was as much emphasis on the use of CBD for our terminal pets and the safety and efficacy of it just a year and a half ago as there is now. I was crying the other day talking to my husband about this bc I feel that it, and we could’ve helped her be so much more comfortable…I feel I failed her. In my opinion, with you being in the same situation…I was 1,000% use this on your baby!!! If I had the information back then, i wouldn’t have given it a second thought!!! Best of luck to you!! Sorry this was so long! Prayers for you and your pup!!
If you live in a state where CBD is legal for your condition, it’s best to buy it from a state-regulated dispensary. But even there, oversight is uneven. “I feel safe being a cannabis consumer in Colorado, since the state tracks everything from seed to sale, but I didn’t the first few years after cannabis became legal,” when the rules were still taking shape, says Robyn Griggs Lawrence, the Boulder author of The Cannabis Kitchen Cookbook, which features recipes for cannabis edibles.
Other desirable features of hemp fibers are strength and durability (particularly resistance to decay), which made hemp useful in the past for rope, nets, sail-cloth, and oakum for caulking. During the age of sailing ships, Cannabis was considered to provide the very best of canvas, and indeed this word is derived from Cannabis. Several factors combined to decrease the popularity of hemp in the late 19th and early 20th centuries. Increasing limitation of cheap labor for traditional production in Europe and the New World led to the creation of some mechanical inventions, but too late to counter growing interest in competitive crops. Development of other natural fibers as well as synthetic fibers increased competition for hemp’s uses as a textile fiber and for cordage. Hemp rag had been much used for paper, but the 19th century introduction of the chemical woodpulping process considerably lowered demand for hemp. The demise of the sail diminished the market for canvas. Increasing use of the plant for drugs gave hemp a bad image. All this led to the discontinuation of hemp cultivation in the early and middle parts of the 20th century in much of the world where cheap labor was limited. In the 19th century softer fabrics took over the clothing market, and today, hemp constitutes only about 1% of the natural fiber market. At least some production of hemp for fiber still occurs in Russia, China, the Ukraine, Poland, Hungary, the countries of the former Yugoslavia, Romania, Korea, Chile, and Peru. There has been renewed interest in England, Australia, and South Africa in cultivating fiber hemp. Italy has an outstanding reputation for high-quality hemp, but productivity has waned for the last several decades. In France, a market for high-quality paper, ironically largely cigarette paper, has developed (such paper is completely free of the intoxicating resin). Modern plant breeding in Europe has produced several dozen hemp strains, although by comparison with other fiber crops there are relatively few described varieties of hemp. Since World War II, breeding has been concerned most particularly with the development of monoecious varieties. Gehl (1995) reviewed fiber hemp development in Canada in the early 20th century, and concluded that the prospects for a traditional fiber industry were poor. However, as outlined below, there are now many non-traditional usages for hemp fiber which require consideration. Hemp long fiber is one of the strongest and most durable of natural fibers, with high tensile strength, wet strength, and other characteristics that make it technically suited for various industrial products (Karus and Leson 1996).
