^ Juliet Eilperin (February 11, 2013), "'Good seed' versus 'evil weed': Hemp activists eye legalization", The Washington Post – via The Japan Times Online, [A] couple of factors — the high taxes the federal government imposed on growing hemp in the late 1930s and again in the early '50s, and then the DEA's interpretation of the 1970 law — made producing hemp nearly impossible. Since the DEA only grants permits in rare instances and demands costly, elaborate security precautions, large-scale hemp growing in the United States is not viable.

CBD Sleep

The use of Cannabis as a mind-altering drug has been documented by archaeological finds in prehistoric societies in Eurasia and Africa.[85] The oldest written record of cannabis usage is the Greek historian Herodotus's reference to the central Eurasian Scythians taking cannabis steam baths.[86] His (c. 440 BCE) Histories records, "The Scythians, as I said, take some of this hemp-seed [presumably, flowers], and, creeping under the felt coverings, throw it upon the red-hot stones; immediately it smokes, and gives out such a vapour as no Grecian vapour-bath can exceed; the Scyths, delighted, shout for joy."[87] Classical Greeks and Romans were using cannabis, while in the Middle East, use spread throughout the Islamic empire to North Africa. In 1545, cannabis spread to the western hemisphere where Spaniards imported it to Chile for its use as fiber. In North America, cannabis, in the form of hemp, was grown for use in rope, clothing and paper.[88][89][90][91]
“It’s apparent ability to enhance the activation of serotonin 1A receptors supports the possibility that it could be used to ameliorate disorders that include: opioid dependence, neuropathic pain, depression and anxiety disorders, nausea and vomiting (e.g. from chemotherapy), and negative symptoms of schizophrenia,” he said. “One big unanswered question is what the human clinical relevance and importance of each of these potential therapeutic uses of CBD, identified solely by examining data from non-human preclinical research, actually is.”
The pulp and paper industry based on wood has considered the use of hemp for pulp, but only on an experimental basis. Hemp’s long fibers could make paper more recyclable. Since virgin pulp is required for added strength in the recycling of paper, hemp pulp would allow for at least twice as many cycles as wood pulp. However, various analyses have concluded that the use of hemp for conventional paper pulp is not profitable (Fertig 1996).
It is often claimed by growers and breeders of herbal cannabis that advances in breeding and cultivation techniques have increased the potency of cannabis since the late 1960s and early '70s when THC was first discovered and understood. However, potent seedless cannabis such as "Thai sticks" were already available at that time. Sinsemilla (Spanish for "without seed") is the dried, seedless inflorescences of female cannabis plants. Because THC production drops off once pollination occurs, the male plants (which produce little THC themselves) are eliminated before they shed pollen to prevent pollination. Advanced cultivation techniques such as hydroponics, cloning, high-intensity artificial lighting, and the sea of green method are frequently employed as a response (in part) to prohibition enforcement efforts that make outdoor cultivation more risky. It is often cited that the average levels of THC in cannabis sold in the United States rose dramatically between the 1970s and 2000, but such statements are likely skewed because undue weight is given to much more expensive and potent, but less prevalent samples.[253]
While normally I'd be slightly tripped up by little things like an overly crowded subway car or a full inbox at work, the CBD oil seems to have taken the edge off of my anxiety a bit. Rather than overthinking a sternly worded email or analyzing a social interaction, I've found it easier to recognize the irrationality of these thoughts and actually let them go (instead of ruminating on the situation). In some ways, I feel more like myself. With that said, I've still experienced some social anxiety when meeting new groups of people—I'd be interested to see what taking the full recommended dose would do.

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.

States have passed laws creating or allowing for the establishment of industrial hemp research or pilot programs. State agencies and institutions of higher education administer these programs in order to study the cultivation, processing, and economics of industrial hemp. Pilot programs may be limited to a certain period of time and may require periodic reporting from participants and state agencies. Some states establish specific regulatory agencies or committees, rules, and goals to oversee the research programs. States may also require coordination between specific colleges or universities and the programs, in other states coordination is optional. From 2015 to 2016, seven states enacted legislation to create hemp research or pilot programs, including Pennsylvania (H.B. 976) and Hawaii (S.B. 2659).

I work at Earthbound Trading Company, therefore discovering the CBD line. By far, one of my favorite products in our store! I had a nurse come in with chronic back pain and fibromyalgia. I recommended the CBD intensive cream. At a later date, she returned to the store to let me know that we sold her a miracle in a jar. She said that for the first time in years she was the most relaxed at work that she has ever been since she started nursing. She applied it while at work and said that she was pain free for 10 out of her 12 hour shift! I, myself, have been having some sharp, shooting back pain the last two weeks. The intensive cream has worked wonders! I applied it at one in the afternoon, and I was pain free for 12 hours! Plus, you can literally feel it working. Such an amazing product. You definitely can’t find that kind of pain relief over the counter or in your local pharmacy.

As a result of intensive selection in cultivation, Cannabis exhibits many sexual phenotypes that can be described in terms of the ratio of female to male flowers occurring in the individual, or typical in the cultivar.[28] Dioecious varieties are preferred for drug production, where the female flowers are used. Dioecious varieties are also preferred for textile fiber production, whereas monoecious varieties are preferred for pulp and paper production. It has been suggested that the presence of monoecy can be used to differentiate licit crops of monoecious hemp from illicit drug crops.[22] However, sativa strains often produce monoecious individuals, probably as a result of inbreeding.
CBD Oil refers to CBD-infused products that contain CBD suspended in an oily base, such as vegetable glycerin, hempseed oil, or another plant-derived oil. Sublingual oils are ideal because they allow for rapid absorption of CBD through the membrane under your tongue directly into your bloodstream. CBD Oils are available in both low and high doses, and droppers built into the cap make it easy to measure your proper dose. CBD Oils are the most popular kind of CBD product thanks to their ease of use and rapid effects.

The list includes marijuana (undifferentiated by strain) and heroin. (While the federal government oversees marijuana research, marijuana use is regulated, in part, by state laws.) As a result, scientists who study the compound must follow a host of restrictive rules. Last year, responding to a request from several governors to change marijuana’s designation, the Drug Enforcement Administration announced that all cannabis would remain a Schedule 1 drug.

However, the medication that they need is not the same as what our medicines applies to us because there is still a difference in the body systems of each mammal. It was mentioned on researches that they haven’t found an effective cure for dogs with those kinds of diseases because each breed has also differenced in their defense systems inside their body. However, there has been recent news about a hemp cbd oil for dogs that was proven to be effective against seizures and other diseases that have no known cure yet.
In December 2012, the U.S. state of Washington became the first state to officially legalize cannabis in a state law (Washington Initiative 502) (but still illegal by federal law),[227] with the state of Colorado following close behind (Colorado Amendment 64).[228] On January 1, 2013, the first marijuana "club" for private marijuana smoking (no buying or selling, however) was allowed for the first time in Colorado.[229] The California Supreme Court decided in May 2013 that local governments can ban medical marijuana dispensaries despite a state law in California that permits the use of cannabis for medical purposes. At least 180 cities across California have enacted bans in recent years.[230]
After seasonal harvests of specific cultivars, these high-CBD hemp crops are put through a specialized solvent-free extraction process to yield a hemp oil that is naturally high in cannabidiol. This pure hemp extract is then tested for safety, quality, and cannabinoid content before being exported to our processing facilities in the United States. Importing any cannabis or hemp product into the United States is a complicated and serious task, so we leave nothing to chance before our high-CBD hemp oil makes its journey across the Atlantic Ocean.

Only a handful of countries have legalized recreational marijuana. Uruguay was one of the first, in 2013. The Netherlands is perhaps the country most known for legal marijuana, yet the drug is illegal there. Spain has given its citizens the rights to grow and consume cannabis privately. Peru also allows citizens to possess marijuana as long as it is for personal, private use. As in Costa Rica, where people can have a “small amount,” without legal trouble.
If your state has legalized both compounds, look for a cream with 1:1 CBD to THC as well as another cannabinoid BCP (beta-caryophyllene) if possible, which manufacturers have seen better results with, Gerdeman suggests. Try Apothecanna's Extra Strength Relieving Creme ($20; apothecanna.com) or Whoopi & Maya's Medical Cannabis Rub (yes, that's Whoopi Goldberg's line), which was designed specifically for menstrual aches and pains (whoopiandmaya.com).
Because of this classification, it's not easy for researchers to get their hands on the drug. "That's not to say you can't do it, but there are hoops you need to jump through that can be a pain, which may deter researchers from going into this space," Bonn-Miller said. "Relatively speaking, it's a small group of people in the U.S. that do research on cannabinoids in humans."
Access to viable seed may present a challenge for research programs and commercial growers. To implement commercial and research hemp programs, farmers need access to seeds that are guaranteed to produce plants that fall under the legal definition of hemp. These seeds can be difficult to obtain, however, because hemp is still regulated under the federal Controlled Substances Act. In response to this problem, Colorado’s governor sent a letter to the U.S. secretary of agriculture in 2014 requesting the federal government address hemp seed regulations.
An absence of such fiber-strain traits as tallness, limited branching, long internodes, and very hollow stems, is characteristic of narcotic strains. Drug forms have historically been grown in areas south of the north-temperate zone, often close to the equator, and are photoperiodically adapted to a long season. When grown in north-temperate climates maturation is much-delayed until late fall, or the plants succumb to cold weather before they are able to produce seeds. Unlike fiber strains that have been selected to grow well at extremely high densities, drug strains tend to be less persistent when grown in high concentration (de Meijer 1994). Drug strains can be very similar in appearance to fiber strains. However, a characteristic type of narcotic plant was selected in southern Asia, particularly in India and neighboring countries. This is dioecious, short (about a meter in height), highly branched, with large leaves (i.e. wide leaflets), and it is slow to mature. The appearance is rather like a short, conical Christmas tree.

Our bodies are thought to produce endocannabinoids by the billions every day. “We always thought the ‘runner’s high’ was due to the release of dopamine and endorphins. But now we know the euphoria is also from an endocannabinoid called anandamide,” its name derived from the Sanskrit word for bliss, says Joseph Maroon, M.D., clinical professor and vice chairman of neurosurgery at the University of Pittsburgh Medical Center. We produce these natural chemicals all day, but they fade quickly because enzymes pop up to destroy them. That’s where CBD comes in: By blocking these enzymes, CBD allows the beneficial compounds to linger. This is why Amanda Oliver, 31, a career consultant in Charleston, SC, pops a CBD gummy bear each night before bed. “I used to lie there tossing and turning as my mind raced from work projects to whether I had set the home alarm,” Oliver says. One piece of candy with 15 mg of CBD is enough to shut off her brain and facilitate sleep. She also swears by the CBD oil she takes at the height of her period, which she says quells her debilitating cramps.

Over millennia, humans have domesticated, developed and cultivated multiple strains of cannabis and used them for a variety of purposes. Today, generally speaking, the two you’ll hear the most about are hemp, which is legally defined as cannabis plants that contain less than 0.3% of the psychoactive THC, and marijuana (strictly speaking, a product rather than a plant type), which has more than 0.3% THC. Many CBD products for dogs are sourced from hemp.
• 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."
As detailed below, the development of hemp as a new legal crop in North America must be considered in relation to illicit cultivation, so it is important to appreciate the scope of the drug situation. Up until the first half of the 20th century, drug preparations of Cannabis were used predominantly as a recreational inebriant in poor countries and the lower socio-economic classes of developed nations. After World War II, marijuana became associated with the rise of a hedonistic, psychedelic ethos, first in the United States and eventually over much of the world, with the consequent development of a huge international illicit market that exceeds the value of the hemp market during its heyday. Table 3 shows the “economic significance” (dollars generated in the black market plus dollar cost of control measures) of the illicit drug industry associated with C. sativa, and contrasts this with the estimated dollar value of major categories of legitimate uses. In the Netherlands, the annual value of narcotic hemp cultivation (ca. $10 billion) exceeds the value of tulips (Collins 1999). Marijuana has become the most widely disseminated illicit species in the world (Schultes and Hofmann 1980). With the exception of alcohol, it is the most widely used recreational euphoric drug. About 25% of North Americans are believed to have used Cannabis illegally. According to the US National Institute on Drug Abuse (www.nida.nih.gov/Infofax/marijuana.html), more than 72 million Americans (33%) 12 years of age and older have tried marijuana. Cultivation, commerce, and consumption of drug preparations of Cannabis have been proscribed in most countries during the present century. The cost of enforcing the laws against Cannabis in North America is in the billions of dollars annually. In addition, there are substantial social costs, such as adverse effects on users, particularly those who are convicted. Tragically this includes some legitimate farmers who, faced with financial ruin because of the unprofitability of crops being grown, converted to growing marijuana.
He described an experiment that was done in Brazil in which a 200mg/day dosage of CBD was added to the anticonvulsants epilepsy patients were currently taking. Over the course of several months only 1 of the 7 patients showed no improvement; three became seizure-free; one experienced only one or two seizures, and two experienced reduced severity and occurrence of seizures.
Our award-winning support staff, experienced cultivators, and network of healthcare practitioners are here to help remove barriers to medical cannabis. We’re honoured to be part of a movement that’s helping Canadians across the country access their medicine; and as we grow we will continue to provide patients with reliable access to safe, consistent, and effective medical cannabis.
A 2012 review found that the THC content in marijuana had increased worldwide from 1970 to 2009.[160] 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.[161]
If you don't live in a legalized state, you can typically still get CBD-infused creams. Since there's no regulation or standardized testing, your best bet is to find trustworthy brands who use creams free of toxins but with additional pain relievers like menthol, capsaicin, lemongrass, or camphor. Try Mary's Nutritionals Muscle Freeze ($70; marysnutritionals.com) or Elixinol's CBD Rescue Balm ($40; elixinol.com).
Global spending on legal cannabis worldwide will hit $57 billion in a decade, according to Arcview Market Research and BDS Analytics. Driven by the legalization of recreational and medical cannabis and the increasing demand for both, legal cannabis revenue in the U.S. is projected to hit $23.4 billion by 2022. Yahoo Finance is now tracking the major players in the cannabis industry.

• The results of a study led by Dr. Joe Wakshlag, associate professor and section chief of nutrition at Cornell, currently under review for publication, also contribute to the knowledge bank. According to the abstract, its objectives were to “determine the basic oral pharmacokinetics, determine safety and assess efficacy of CBD oil in managing pain in dogs with osteoarthritis.” The Canine Brief Pain Inventory and Hudson activity scores reportedly showed a clinically significant reduction in pain and an increase in activity with CBD treatment.

Cannabidiol (CBD), the non-psychoactive compound found in the Marijuana plant, has become a fast-growing topic due to the wide of array of medical benefits it provides for people around the world.  CBD can be used to provide relief for over fifty conditions including anxiety, depression, chronic pain, and more! If you or a loved one is experiencing any of these conditions, CBD may provide the relief they need. Included in those loved ones aren’t just the ones with two legs.
Cannabinoids, terpenoids, and other compounds are secreted by glandular trichomes that occur most abundantly on the floral calyxes and bracts of female plants.[42] As a drug it usually comes in the form of dried flower buds (marijuana), resin (hashish), or various extracts collectively known as hashish oil.[8] In the early 20th century, it became illegal in most of the world to cultivate or possess Cannabis for sale or personal use.
A review published in 2017 in the journal Frontiers in Pharmacology described how CBD may work to protect the hippocampus — the part of the brain responsible for several important functions, such as learning, memory and navigation — during times of stress, and may also help prevent brain-cell destruction that results from schizophrenia. Another 2017 review published in the journal Annals of Palliative Medicine summarized a handful of studies that suggest cannabis oils containing THC or CBD, or both, may help with chronic pain management, but the mechanism is unclear.
Cannabis plants produce a unique family of terpeno-phenolic compounds called cannabinoids, some of which produce the "high" which may be experienced from consuming marijuana. There are 483 identifiable chemical constituents known to exist in the cannabis plant,[49] and at least 85 different cannabinoids have been isolated from the plant.[50] The two cannabinoids usually produced in greatest abundance are cannabidiol (CBD) and/or Δ9-tetrahydrocannabinol (THC), but only THC is psychoactive.[51] Since the early 1970s, Cannabis plants have been categorized by their chemical phenotype or "chemotype", based on the overall amount of THC produced, and on the ratio of THC to CBD.[52] Although overall cannabinoid production is influenced by environmental factors, the THC/CBD ratio is genetically determined and remains fixed throughout the life of a plant.[37] Non-drug plants produce relatively low levels of THC and high levels of CBD, while drug plants produce high levels of THC and low levels of CBD. When plants of these two chemotypes cross-pollinate, the plants in the first filial (F1) generation have an intermediate chemotype and produce intermedite amounts of CBD and THC. Female plants of this chemotype may produce enough THC to be utilized for drug production.[52][53]
California’s legalization spurred Dr. Geoffrey Guy and Dr. Brian Whittle to found GW Pharmaceuticals, a company that would utilize clinical trials to unpack various cannabinoid formulations as potential therapies with the overriding focus of developing what would later be known as Sativex (Nabiximols). This oral mucosal spray was made up of CBD and THC in a 1:1 ratio and successfully combated neuropathic pain, spasticity, overactive bladder, and symptoms of multiple sclerosis.
For dogs suffering from rashes, skin allergies, arthritis, or other general forms of muscle aches/joint pains (due to old age or otherwise), CBD topicals (salves and creams) are a popular and convenient way to go — they’re reliable, convenient, efficient for acute pain, and for the most part, are super easy to administer (have you ever know a dog that doesn’t love a good rub-down?).

It has been contended that hemp is notably superior to most crops in terms of biomass production, but van der Werf (1994b) noted that the annual dry matter yield of hemp (rarely approaching 20 t/ha) is not exceptional compared to maize, beet, or potato. Nevertheless, hemp has been rated on a variety of criteria as one of the best crops available to produce energy in Europe (Biewinga and van der Bijl 1996). Hemp, especially the hurds, can be burned as is or processed into charcoal, methanol, methane, or gasoline through pyrolysis (destructive distillation). As with maize, hemp can also be used to create ethanol. However, hemp for such biomass purposes is a doubtful venture in North America. Conversion of hemp biomass into fuel or alcohol is impractical on this continent, where there are abundant supplies of wood, and energy can be produced relatively cheaply from a variety of sources. Mallik et al. (1990) studied the possibility of using hemp for “biogas” (i.e. methane) production, and concluded that it was unsuitable for this purpose. Pinfold Consulting (1998) concluded that while there may be some potential for hemp biomass fuel near areas where hemp is cultivated, “a fuel ethanol industry is not expected to develop based on hemp.”

Although hemp and marijuana are both varieties of cannabis, there is a difference between them. The differences between these cannabis varieties are primarily evident in the way each plant is used. These differences are also documented in the language, laws, and regulations that apply to each variety. In this introduction to hemp, we’ll break down the anatomy, history, use, and legality of the hemp plant to get to the heart of not only what distinguishes it from marijuana, but also what makes it such a viable, versatile commodity.
Ringo’s Gift: This cultivar is named after the cannabidiol pioneer, Lawrence Ringo. Ringo’s Gift is a cross between two other CBD-rich strains, AC/DC and Harle-tsu. Its CBD to THC ratio varies from 1:1 to 22:1, but it consistently favors CBD. Ringo’s Gift smells of earthy pine and promises full-bodied relaxation in tandem with calming cerebral effects which, together, silence pain and anxiety.
Many countries differentiate between marijuana and hemp by the amount of THC produced per weight of a dry plant. In the U.S., industrial hemp is defined as “the plant Cannabis sativa L. and any part of such plant, whether growing or not, with a delta-9 THC concentration of not more than 0.3 percent on a dry weight basis.” The European Union has set the limit at 0.2 percent, while in Great Britain the limit is zero, unless you have a cultivation license to grow industrial hemp with no more than 0.2% THC.
The word cannabis is from Greek κάνναβις (kánnabis) (see Latin cannabis),[135] which was originally Scythian or Thracian.[136] It is related to the Persian kanab, the English canvas and possibly even to the English hemp (Old English hænep).[136] In modern Hebrew, קַנַּבּוֹס qannabōs (modern pronunciation: [kanaˈbos]) is used but there are those who have theorized that it was referred to in antiquity as קני בושם q'nei bosem, a component of the biblical anointing oil.[137][138] Old Akkadian qunnabtu, Neo-Assyrian and Neo-Babylonian qunnabu were used to refer to the plant meaning "a way to produce smoke".[139][140][141]

Canaccord Genuity Inc., the biggest underwriter of stock offerings for weed-related companies, has appointed a head of European cannabis investment banking. The firms are laying the groundwork for an expected increase in stock sales and mergers and acquisitions as companies seek to capitalize on Europe’s growing acceptance of cannabis, particularly for medical uses.
When privacy isn’t a requirement, outdoor cannabis grows can provide many advantages over indoor operations. Sunlight is the single most important factor for successful outdoor marijuana growing. It’s important to choose a plot with total sunshine throughout the day. Therefore, cannabis growers in the northern hemisphere will want plots with southern exposure, exposing marijuana plants to the sun’s arc across the sky.

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.

CBD is famous for the promise it holds for treating treatment-resistant forms of childhood epilepsy. A number of clinical trials, testing the efficacy of CBD in human epilepsy patients, are currently underway. But there is also evidence, mainly from animal studies and in vitro experiments, that CBD may have neuroprotective, anti-inflammatory and analgesic (pain-relieving) properties, and potential therapeutic value in the treatment of motivational disorders like depression, anxiety, and addiction.
