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.

Ultimately, CBD is a form of medical marijuana that takes out the THC to create a nontoxic form. There are many uses for these Hemp oils and helping our furry friends is a great place to start. Whether this article helped you decide you want to try CBD for your dog or yourself you now know what they are all about. A lot of good can come from CBD for dogs, and the benefits they can carry.

Many dog owners are already making their dog treat. They personalize it according to their pet’s likes and favorites. Pet owners can also infuse the CBD compound into their homemade cbd treats for dogs. In this way, their dogs will enjoy their food while ingesting the cannabidiol compound. Homemade CBD treats are made by merely adding CBD oil supplements to your dog treat recipe. Each 1-ounce bottle of CBD oil supplement contains 100 mg of CBD while a container of 2-ounce includes 500 mg of CBD. Another good thing about making homemade CBD dog treat is that the dosage of CBD compound given to your dog is controlled and regulated. In that way, you can track his consumption, and you can adjust the dosage according to the effect of the dog treat to your dog.

In 1976, Canadian botanist Ernest Small[66] and American taxonomist Arthur Cronquist published a taxonomic revision that recognizes a single species of Cannabis with two subspecies: C. sativa L. subsp. sativa, and C. sativa L. subsp. indica (Lam.) Small & Cronq.[62] The authors hypothesized that the two subspecies diverged primarily as a result of human selection; C. sativa subsp. sativa was presumably selected for traits that enhance fiber or seed production, whereas C. sativa subsp. indica was primarily selected for drug production. Within these two subspecies, Small and Cronquist described C. sativa L. subsp. sativa var. spontanea Vav. as a wild or escaped variety of low-intoxicant Cannabis, and C. sativa subsp. indica var. kafiristanica (Vav.) Small & Cronq. as a wild or escaped variety of the high-intoxicant type. This classification was based on several factors including interfertility, chromosome uniformity, chemotype, and numerical analysis of phenotypic characters.[52][62][67]
Hemp, (Cannabis sativa), also called industrial hemp, plant of the family Cannabaceae cultivated for its fibre (bast fibre) or its edible seeds. Hemp is sometimes confused with the cannabis plants that serve as sources of the drug marijuana and the drug preparation hashish. Although all three products—hemp, marijuana, and hashish—contain tetrahydrocannabinol (THC), a compound that produces psychoactive effects in humans, the variety of cannabis cultivated for hemp has only small amounts of THC relative to that grown for the production of marijuana or hashish.

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?).


And this doesn’t stop at cannabinoids. What Raber and other researchers are pursuing is essentially a reconstruction of cannabis’ chemical profile. Terpenes, for example, are what give weed its characteristic smell, yet you’ll find these across the plant kingdom: Limonene isn’t super abundant in cannabis, but it is an abundant product of the citrus industry. The idea is that instead of going through the grief of extracting small amounts of limonene from a cannabis plant, you can get it from lemons instead.
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.

"It's important to know that the research in this area is in its infancy, partly because we haven't really understood much about CBD until relatively recently," said Marcel Bonn-Miller, an adjunct assistant professor at the University of Pennsylvania Perelman School of Medicine. He pointed out that the classification of marijuana as a Schedule 1 drug by the DEA makes it difficult to get material to use in laboratory studies. Schedule 1 drugs have a high potential for abuse, according to the DEA, and are illegal under federal law.
Cannabinoids are a class of compounds that interact with receptors throughout your body. CBD is just one of dozens of cannabinoids found in cannabis, including tetrahydrocannabinol (THC), which is the one responsible for marijuana’s famous high. Medical cannabis is technically any cannabis product used for medicinal purposes, and these can contain THC or CBD or both, said Nick Jikomes, a neuroscientist at Leafly, a website that provides information about legal cannabis. “A common mistake people make is to think that CBD is ‘the medical cannabinoid’ and THC is ‘the recreational cannabinoid.’” That’s inaccurate, he said, because THC is a potent anti-inflammatory and can be helpful for pain.
While CBD can be extracted from non-hemp varieties of the plant, hemp-derived CBD is less restricted by the government because of its inherently low levels of THC. CBD from hemp is legal for sale in most US states, while CBD products derived from non-hemp varieties can contain noticeable amounts of THC, and are therefore subject to stricter laws and regulations.

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.
CBD concentrates typically contain the strongest dosage of CBD compared to any other CBD products. It can contain up to 10 times the average CBD products. Concentrates are also convenient in that it only takes a few seconds to consume. Overall, CBD concentrates seem to be most popular among customers who are extremely busy, yet seek high potency CBD.

Write everything down–take copious notes. Over a period of time start to look for trends. Try and notice nuances towards a change in your dog’s behavior, activity level and in the general quality of life of your dog. Be observant and write it down. Consistency is what is going to determine the window of opportunity to fully capture the healing benefits of CBD.
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.
Following an 1836–1840 travel in North Africa and the Middle East, French physician Jacques-Joseph Moreau wrote on the psychological effects of cannabis use; he was a member of Paris' Club des Hashischins.[citation needed] In 1842, Irish physician William Brooke O'Shaughnessy, who had studied the drug while working as a medical officer in Bengal with the East India company, brought a quantity of cannabis with him on his return to Britain, provoking renewed interest in the West.[205] Examples of classic literature of the period featuring cannabis include Les paradis artificiels (1860) by Charles Baudelaire and The Hasheesh Eater (1857) by Fitz Hugh Ludlow.

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]
There is certainly a need to utilize available germplasm sources in order to breed suitable cultivars for North America. A list of the 24 approved cultivars for the 2001 season in Canada is at www.hc-sc.gc.ca/hpb-dgps/therapeut/htmleng/hemp.html. Most of these are regulated by the European Organization of Economic Cooperation and Development (OECD). These cultivars are “approved” for use in Canada not on agricultural criteria, but merely on the basis that they meet the THC criterion. Indeed, most of these are unsuitable or only marginally suitable for Canada (Small and Marcus 2000), and only a very few Canadian cultivars to date have been created. In Canada, every acquisition of hemp grown at a particular place and time must be tested for THC content by an independent laboratory and, under the industrial hemp regulations, fields of hemp with more than 0.3% THC may require destruction (a slight degree of flexibility is generally exercised). Importation of experimental hemp lines (i.e. other than the approved cultivars) requires importation licenses (as well as phytosanitary clearance of the shipment by the Canadian Food Inspection Agency), and the importation licenses require an indication that the THC contents are low.
It’s also worth noting that more and more people now use cannabis for medicinal purposes, as it is known to offer pain relief for some chronic conditions, as well as stimulate the appetite for people who are sick and may not feel like eating (such as cancer patients undergoing chemotherapy). Despite evidence that cannabis has medical benefits, you should always discuss your options for medical treatment with your doctor and use medical cannabis under their supervision.

Thank you for sharing your story. It is amazing the stories I have heard and the things you here the politicians debating over. The truth is out. They need to get over there guilty pride and pharmaceutical needs to be slapped down a few pegs. This is happening we just need to defend the corporations that back the oil, the pharma, any other corporation that doesn’t fight a health and balance model.

I assume this is also a side effect of the eased anxiety, but I seem to fall asleep within the 20- to 30-minute range rather than my normal 45 minutes to one hour (or longer). Not only do I seem to be skipping (or at least shortening) the whole tossing-and-turning phase of my sleep cycle, but I'm able to snap out of the overthinking mindset that often keeps me up at night. Of course, there's no telling whether a big life event would kindly disrupt this newfound bliss, but I'd like to think it's helped on day-to-day basis.

The cool thing is that humans are not the only species known to have this Endocannabinoid system. Many species have been shown in research to have these receptors that cannabinoids have an effect too. One of the more popular researched species is dogs who have been shown to have positive reactions to medical marijuana but THC can be toxic for, this is a place for CBD oil for dogs to shine.


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.

Heavy, long-term exposure to marijuana may have biologically based physical, mental, behavioral and social health consequences and may be "associated with diseases of the liver (particularly with co-existing hepatitis C), lungs, heart, and vasculature".[83] It is recommended that cannabis use be stopped before and during pregnancy as it can result in negative outcomes for both the mother and baby.[84][85] However, maternal use of marijuana during pregnancy does not appear to be associated with low birth weight or early delivery after controlling for tobacco use and other confounding factors.[86] A 2014 review found that while cannabis use may be less harmful than alcohol use, the recommendation to substitute it for problematic drinking was premature without further study.[87] Various surveys conducted between 2015 and 2019 found that many users of cannabis substitute it for prescription drugs (including opioids), alcohol, and tobacco; most of those who used it in place of alcohol or tobacco either reduced or stopped their intake of the latter substances.[88]

In 2019, the European Food Safety Authority (EFSA) announced that CBD and other cannabinoids would be classified as "novel foods",[84] meaning that CBD products would require authorization under the EU Novel Food Regulation stating: because "this product was not used as a food or food ingredient before 15 May 1997, before it may be placed on the market in the EU as a food or food ingredient, a safety assessment under the Novel Food Regulation is required."[85] The recommendation – applying to CBD extracts, synthesized CBD, and all CBD products, including CBD oil – was scheduled for a final ruling by the European Commission in March 2019.[84] If approved, manufacturers of CBD products would be required to conduct safety tests and prove safe consumption, indicating that CBD products would not be eligible for legal commerce until at least 2021.[84]
Hemp seeds have an attractive nutty taste, and are now incorporated into many food preparations (Fig. 34), often mimicking familiar foods. Those sold in North America include nutritional (granola-type) or snack bars, “nut butters” and other spreads, bread, pretzels, cookies, yogurts, pancakes, porridge, fruit crumble, frozen dessert (“ice cream”), pasta, burgers, pizza, salt substitute, salad dressings, mayonnaise, “cheese,” and beverages (“milk,” “lemonade,” “beer,” “wine,” “coffee nog”). Hemp seed is often found canned or vacuum-packed (Fig. 35). Alcoholic beverages made with hemp utilize hempseed as a flavorant. Hemp food products currently have a niche market, based particularly on natural food and specialty food outlets.

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.

Air-dried stem yields in Ontario have from 1998 and onward ranged from 2.6–14.0 tonnes of dry, retted stalks per hectare (1–5.5 t/ac) at 12% moisture. Yields in Kent County, have averaged 8.75 t/ha (3.5 t/ac). Northern Ontario crops averaged 6.1 t/ha (2.5 t/ac) in 1998. Statistic for the European Union for 2008 to 2010 say that the average yield of hemp straw has varied between 6.3 and 7.3 ton per ha.[71][72] Only a part of that is bast fiber. Around one tonne of bast fiber and 2–3 tonnes of core material can be decorticated from 3–4 tonnes of good-quality, dry-retted straw. For an annual yield of this level is it in Ontario recommended to add nitrogen (N):70–110 kg/ha, phosphate (P2O5): up to 80 kg/ha and potash (K2O): 40–90 kg/ha.[73] The average yield of dry hemp stalks in Europe was 6 ton/ha (2.4 ton/ac) in 2001 and 2002.[14]
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]

What separates CBD products from nicotine products? The difference is massive, and one of the many reasons why people are turning to vape CBD is because of its many medical benefits. As there are still others that believe that CBD is the same as THC, many would even think that it has psychoactive effects which are not true at all. CBD is safe for everyone to use and it has nothing but medical advantages to offer.

CBD’s action within the brain and body is quite complicated. To date, scientists have discovered more than a dozen different mechanisms of action, or ways that CBD affect us. It’s very likely that the beneficial effects of CBD are a result of the total of its activation of all of these biological pathways, not a single one in particular. Much more research is needed to fully understand the mechanisms by which CBD relieves ailments such as anxiety and seizures.

The confusion compounds when one realizes that in today’s popular lexicon, the terms indica, sativa, and hybrid tend to indicate a set of effects, rather than the taxonomy of a particular strain. But that’s just as well. Most marijuana strains today, especially those under commercial cultivation, are genetic hybrids. Only a handful of pure, or “landrace” cannabis strains are in circulation.

Short-term use increases both minor and major adverse effects.[104] Common side effects include dizziness, feeling tired, vomiting, and hallucinations.[104] Long-term effects of cannabis are not clear.[106] Concerns including memory and cognition problems, risk of addiction, schizophrenia in young people, and the risk of children taking it by accident.[103]


Selection for fiber has resulted in strains that have much more bark fiber tissues and much less woody core than encountered in narcotic strains, oilseed strains, and wild plants (Fig. 12). In non-fiber strains of Cannabis, bark can be less than one quarter of the stem tissues (i.e. more than three quarters can be woody core). By contrast, in fiber strains half of the stem tissues can be bark, and more than half of this can be the desirable long primary fibers (de Meijer 1995). Non-fiber strains rarely have as much as 15% fiber in the bark.
Hemp fibers are primarily used for textiles, paper, building materials, and other industrial products. Hurds, or shives, are short woody hemp fibers typically found inside the stalk. They’re used to make hempcrete, bedding materials, absorbents, particle board, ceiling panels, compost, and other industrial products. Bast fibers make up the outer portion of the stalk and are typically split into three categories — primary, or line fiber, secondary, and the tow. They are categorized according to their cell strength and cell wall thickness, which will determine the fiber’s strength, durability, and ultimately what the it can be used for.

Cannatonic: A potent pain-reliever, Cannatonic hails from Spain and stands as one of the earliest cultivars to be bred for its high CBD content. This cultivar is a cross between MK Ultra and G13 Haze, and it helps relieves anxiety, muscle spasms, pain, and migraines while providing uplifting energy. Cannatonic tends to relax and loosen muscles without locking users to their couches.

CBD was first discovered in 1940 by Roger Adams, a prominent organic chemist at the University of Illinois. Shortly thereafter, other scientists began testing isolated cannabinoids on lab animals; notably, Walter S. Loewe ran trials on mice and rabbits with the cannabinoids THC, CBD and CBN. He found that CBD produced no observable effects in the animals’ behavior while THC caused, what he called, a “central excitant action” in rabbits. Despite science’s movement forward, scientists were completely unaware of the cannabinoids’ chemical structure, so no one could tell which specific compound resulted in which effect.
Prior to the Hemp Farming Act of 2018, 41 states had passed industrial hemp-related legislation. 39 of those states legalized statewide hemp cultivation programs that defined hemp specifically to differentiate it from marijuana, establish licensing requirements, and regulate production. The Hemp Farming Act now requires state departments of agriculture to consult with their governors and chief law enforcement officers on a hemp regulatory program, which will then be submitted to the United States Secretary of Agriculture for approval. According to Section 297B of the bill, state hemp regulatory programs must include a system to maintain information on all land on which hemp is cultivated, procedures for testing THC levels in hemp, and procedures for disposing of products that violate THC content restrictions.
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]
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]
And without high-quality trials, experts don’t know how much is best for a given purpose. The staff at Roth’s dispensary told her, “Try some once or twice a day and see what happens.” (Half a dropper’s worth was a good amount for her.) One thing scientists feel confident about is that CBD is not dangerous. It won’t damage vital organs even at doses as high as 5,000 mg a day, Marcu says, and nobody has died from simply overdosing on a cannabis product.
While animal studies and particularly those with canines are still in its infancy when it comes to using CBD for dogs, it's very clear that we're heading in the right direction. There are more health benefits of using CBD oil for dogs than we have initially thought a decade ago, and it's possible that even more will be discovered as research continues.
Preliminary work in Germany (noted in Karus and Leson 1994) suggested that hemp could be grown on soils contaminated with heavy metals, while the fiber remained virtually free of the metals. Kozlowski et al. (1995) observed that hemp grew very well on copper-contaminated soil in Poland (although seeds absorbed high levels of copper). Baraniecki (1997) found similar results. Mölleken et al. (1997) studied effects of high concentration of salts of copper, chromium, and zinc on hemp, and demonstrated that some hemp cultivars have potential application to growth in contaminated soils. It would seem unwise to grow hemp as an oilseed on contaminated soils, but such a habitat might be suitable for a fiber or biomass crop. The possibility of using hemp for bioremediation deserves additional study.
Each case is unique, and you must consider your pet’s medical history. There are over 1500 prescription drugs for pets in the United States; each of them could interact in a different way with any supplement such as PurCBD. If your pet is on any prescription medication we recommend consulting with a veterinarian before administering any supplement, including our own. Our comprehensive dosing chart is the best place to start; the second page of the chart has a form to help you and your veterinarian coordinate the use of prescription meds with PurCBD.
