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.
Last year, the Hemp Industries Association (HIA) estimated the total retail value of all hemp products sold in the U.S. at $620 million. Sadly, all of the raw hemp materials were imported from other countries. (More on that later.) Hemp is an attractive rotation crop for farmers. As it grows, hemp breathes in CO2, detoxifies the soil, and prevents soil erosion. What’s left after harvest breaks down into the soil, providing valuable nutrients.
Two dermatologists I consulted with, New York-based Whitney Bowe, MD and New Jersey-based Jeanette Jacknin, MD, both agreed that CBD’s anti-aging and anti-inflammatory benefits are clinically proven. “Studies have shown that the cannabinoids like CBD in marijuana are anti-inflammatory and anti-aging and topical CBD has proven helpful for acne, eczema, and psoriasis,” Jacknin told me. “Hemp seed oil is reputed to be the most unsaturated oil derived from the plant kingdom, so it is less pore clogging but a great moisturizer for dry, cracked skin.”
It’s understandable that many people are frustrated by the ambiguity surrounding CBD and dogs. It often results in pet owners who go with their gut, especially when they think A) an existing medication isn’t working, or B) there are better, “more natural” alternatives. And this is equally frustrating for vets who can’t definitively say anything about it.
We recommend refrigeration out of an abundance of caution. Prolonged exposure to sunlight or heat can cause the oil to prematurely spoil. Heat above 160°F will cause the PurCBD+ to breakdown and become ineffective. Refrigeration is the simplest way to ensure the longest possible shelf life. For most people, however, refrigeration isn't needed—it’s just ideal.

CBD products that don't contain THC fall outside the scope of the U.S. Drug Enforcement Agency's (DEA) Controlled Substances Act, which means CBD products are legal to sell and consume as long as they don't have THC. That's likely one of the reasons why CBD products, including CBD oil, are becoming more socially acceptable and increasingly popular. In 2016, Forbes reported that CBD products are expected to be a $2.2 billion industry by 2020.


Hemp crops are tall, have thick foliage, and can be planted densely, and thus can be grown as a smother crop to kill tough weeds.[47] Using hemp this way can help farmers avoid the use of herbicides, gain organic certification, and gain the benefits of crop rotation. However, due to the plant's rapid and dense growth characteristics, some jurisdictions consider hemp a prohibited and noxious weed, much like Scotch Broom.[48]
Marijuana is the most commonly used illegal drug. The hemp plant Cannabis sativa, from which marijuana grows throughout the world, flourishes in most temperate and tropical regions. Marijuana is commonly ingested by smoking, which increases the bioavailability of the primary psychoactive constituent, tetrahydrocannabinol (THC) (Musty et al., 1995; Hall and Solowij, 1998). Inhalation of marijuana smoke produces euphoria, signs of increased sympathetic nervous system activity, and decreased parasympathetic nervous system activity (Schwartz, 1987). At high doses, however, sympathetic activity is inhibited and parasympathetic activity is increased, leading to bradycardia and hypotension. Reversible ECG abnormalities have been reported, as have increases in supraventricular and ventricular ectopic activity (Ghuran and Nolan, 2000). The clinical relevance of this finding is unclear.
Hempseed's amino acid profile is comparable to other sources of protein such as meat, milk, eggs and soy.[21] Protein digestibility-corrected amino acid scores (PDCAAS), which attempt to measure the degree to which a food for humans is a "complete protein", were 0.49–0.53 for whole hemp seed, 0.46–0.51 for hempseed meal, and 0.63–0.66 for hulled hempseed.[22]
In human clinical trials, CBD has long been studied for its potential application in various medical fields. It's been shown that CBD has the ability to relieve inflammation, relieve pain, reduce seizures, reduce symptoms of psychosis, reduce muscle spasms, and reduce anxiety (Kogan et al. 2007; Dialogues Clin Neurosci). CBD is also being studied for applications in treating cancer.
In 1937, the Marijuana Tax Act strictly regulated the cultivation and sale of all cannabis varieties. The Controlled Substances Act of 1970 classified all forms of cannabis — including hemp — as a Schedule I drug, making it illegal to grow it in the United States (which is why we’re forced to import hemp from other countries as long as it contains scant levels of THC — 0.3% is the regulation for hemp cultivation in the European Union and Canada). As a result of this long-term prohibition, most people have forgotten the industrial uses of the plant and continue to misidentify hemp with its cannabis cousin, marijuana.
CBD is derived from either hemp (the rope and fabric stuff) or cannabis (usually the recreational stuff). It can be easy to get, is purported to offer many health benefits for pets (and people), and comes in anything from pills and oils to specialty treats. Often, you will find CBD in the form of an oil that can be given orally, although there are other products like biscuits and capsules easily found online. Most importantly, it won’t get your dog high, which is good news for dogs because of their extreme sensitivity to THC. 
What exactly is cannabidiol (CBD) and more importantly, what does it do? Those questions and more are at the heart of this comprehensive guide to one of the most fascinating and important compounds of the cannabis plant. Cannabis plants are chemical powerhouses that produce more than 400 different compounds. Not all of those compounds are unique to marijuana, of course, and appear in many other species of plants. That’s why marijuana can smell like pine trees or taste like fresh lemons. But of those 400 compounds, more than 60 of them are totally specific to the plant genus Cannabis. Scientists call these special compounds “cannabinoids.” However, not all cannabinoids are created equal. One of them, cannabidiol, or CBD, holds the key to the wide variety of medicinal and therapeutic effects marijuana offers.
Among the cannabinoids in cannabis, the main psychoactive compound, THC, often outshines the one that provides a natural anti-anxiety, anti-epileptic and antipsychotic effect. Cannabidiol, or CBD oil, lacks the colorful high commonly associated with your traditional marijuana high and doesn’t have much of a noticeable effect when isolated. When combined with THC, the relaxing effect combats any feelings of paranoia or panic that can sometimes be felt under the influence. While lauded for its effect on epilepsy, recent cannabis research has identified CBD as the component responsible for a great deal of marijuana’s medical benefits.
In late 2017, researchers with the University of Guelph in Canada published the first-ever study to document the ideal growing conditions for cannabis. Using liquid organic fertilizer with a PKN ratio of 1.3P–1.7K-4.0N, the experiment tested five increasing rates of fertilization. They also tested two coir-based soil-less growing media, or “substrates.”
The Spaniards brought hemp to the Americas and cultivated it in Chile starting about 1545.[117] Similar attempts were made in Peru, Colombia, and Mexico, but only in Chile did the crop find success.[118] In July 1605, Samuel Champlain reported the use of grass and hemp clothing by the (Wampanoag) people of Cape Cod and the (Nauset) people of Plymouth Bay told him they harvested hemp in their region where it grew wild to a height of 4 to 5 ft. [119] In May 1607, "hempe" was among the crops Gabriel Archer observed being cultivated by the natives at the main Powhatan village, where Richmond, Virginia is now situated;[120] and in 1613, Samuell Argall reported wild hemp "better than that in England" growing along the shores of the upper Potomac. As early as 1619, the first Virginia House of Burgesses passed an Act requiring all planters in Virginia to sow "both English and Indian" hemp on their plantations.[121] The Puritans are first known to have cultivated hemp in New England in 1645.[117]

The main psychoactive constituent of cannabis is tetrahydrocannabinol (THC) (Figure 9). There are numerous other cannabinoids found in smaller concentrations that may contribute to the medical problems associated with the use of marijuana. Hashish is the resinous secretion of the cannabis plant, which contains a high concentration of THC. It is dried, compressed, and smoked in pipes either singly or mixed with tobacco. Marijuana may be smoked as a cigarette (‘joint’) or orally ingested. Smoking has immediate effects whereas ingestion has been associated with unpredictable effects (Ohlsson et al. 1980). THC binds to a family of cannabinoid receptors in the cerebral cortex and interferes with the endogenous cannabinoid neurotransmitter system, causing cognitive, psychomotor, and pain modulatory effects (Calignano et al. 1998). There are physiologic dose-dependent effects on the CB1 receptors found in the pain processing areas of the brain and spinal cord. Heart rate is increased with variable effects on BP. Transient vasodilatation and hypotension may occur (Hillard 2000). These effects are not commonly seen even in severe overdose conditions. Chronic marijuana smokers rapidly develop tolerance to these vascular effects. There have been no reports of lethal marijuana intoxication. Chest pain may occur due to pneumothorax and pneumomediastinum caused by deep inhalations (Brody et al. 1988).
Marijuana or cannabis is the most frequently consumed illicit drug worldwide and in the United States (Rouse 1996). Marijuana is a green or gray mixture of dried shredded flowers and leaves of the hemp plant Cannabis sativa. It is believed that many drug addicts often first experiment with marijuana using it as a stepping stone to more potent or ‘harder’ illicit drugs (Fergusson and Horwood 2000).
Hemp fiber has been used extensively throughout history, with production climaxing soon after being introduced to the New World. For centuries, items ranging from rope, to fabrics, to industrial materials were made from hemp fiber. Hemp was also commonly used to make sail canvas. The word "canvas" is derived from the word cannabis.[24][25] Pure hemp has a texture similar to linen.[26] Because of its versatility for use in a variety of products, today hemp is used in a number of consumer goods, including clothing, shoes, accessories, dog collars, and home wares. For clothing, in some instances, hemp is mixed with lyocell[27]
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.
Various strains of "medical marijuana" are found to have a significant variation in the ratios of CBD-to-THC, and are known to contain other non-psychotropic cannabinoids.[60] Any psychoactive marijuana, regardless of its CBD content, is derived from the flower (or bud) of the genus Cannabis. Non-psychoactive hemp (also commonly-termed industrial hemp), regardless of its CBD content, is any part of the cannabis plant, whether growing or not, containing a ∆-9 tetrahydrocannabinol concentration of no more than 0.3% on a dry-weight basis.[61] Certain standards are required for legal growing, cultivating, and producing the hemp plant. The Colorado Industrial Hemp Program registers growers of industrial hemp and samples crops to verify that the dry-weight THC concentration does not exceed 0.3%.[61]

It is important to note that the federal government still considers cannabis a dangerous drug and that the illegal distribution and sale of marijuana is a serious crime. Under the Controlled Substances Act (CSA), marijuana is still considered a Schedule 1 drug. Cultivation and distribution of marijuana are felonies; possession for personal use is a misdemeanor; possession of “paraphernalia” is also illegal. Cultivating 100 plants or more carries a mandatory minimum sentence of five years according to federal statutes.

I will continue to use bluebird botanical products loyally. Their customer service is exceptional. Their products are of exceptional quality and reasonably priced. Due to the dedication of their staff, I have been given back something I thought was lost to me: HOPE. I cannot thank BlueBird enough for their dedication to sharing a product that improves the quality of life for others.
The overall effect is not assured because, like cannabis — which is illegal under U.S. federal law although some states have allowed medical or recreational use — states will continue to be able to enact laws related to industrial hemp, allowing for a potential patchwork of legislation across the country. Other questions remain in terms of how exactly the Agriculture Department will regulate the plant.
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.
In the EU and Canada, hemp has often been grown as a dual-purpose crop, i.e. for both fiber and oilseed. In France, dual purpose hemp is typically harvested twice—initially the upper seed-bearing part of the stems is cut and threshed with a combine, and subsequently the remaining stems are harvested. Growing hemp to the stage that mature seeds are present compromises the quality of the fiber, because of lignification. As well, the hurds become more difficult to separate. The lower quality fiber, however, is quite utilizable for pulp and non-woven usages.

Hemp has hundreds of uses, many of which are yet to be discovered or fully realized thanks to the lack of available research funds. From textiles and plastics to livestock feed and home cooking, hemp has many applications that can reduce our dependence both on other countries and fossil fuels. Driven by explosive growth in hemp-based consumer products, the global hemp market is expected to jump to $10.6 billion by 2025. Everything from our vodka to our cars is waiting to be reimagined in the future with legal hemp. Many people won’t even realize how much their lives are affected by cannabis-based products.
Senate Majority Leader Mitch McConnell continues to be ardently anti-marijuana, despite the success of these programs and the fact that 62% of Americans say recreational marijuana should be legal. Nevertheless, McConnell and Senate Republicans read the political tea leaves and will now recognize the important differences between marijuana and hemp. In doing so, they’re creating an exciting time for entrepreneurs, CBD advocates, and farmers across the country.
Modern decorticating techniques employ steam explosion (treating the fibers with steam through a pressurized chamber) and ultrasonic breaking (breaking down fibers using ultrasonic waves) to maintain the integrity of the fibers throughout the process. These techniques are not as harsh on the stalks and allow processors to use the fibers on cotton and wool processing machinery.
There are also other difficulties in researching the effects of cannabis. Many people who smoke cannabis also smoke tobacco.[277] This causes confounding factors, where questions arise as to whether the tobacco, the cannabis, or both that have caused a cancer. Another difficulty researchers have is in recruiting people who smoke cannabis into studies. Because cannabis is an illegal drug in many countries, people may be reluctant to take part in research, and if they do agree to take part, they may not say how much cannabis they actually smoke.[278]
In September 2005, New Scientist reported that researchers at the Canberra Institute of Technology had identified a new type of Cannabis based on analysis of mitochondrial and chloroplast DNA.[81] The New Scientist story, which was picked up by many news agencies and web sites, indicated that the research was to be published in the journal Forensic Science International.[82]
Canadian experience with growing hemp commercially for the last 4 years has convinced many growers that it is better to use a single-purpose cultivar, seed or fiber, than a dual-purpose cultivar. The recent focus of Canadian hemp breeders has been to develop cultivars with high seed yields, low stature (to avoid channeling the plants’ energy into stalk, as is the case in fiber cultivars), early maturation (for the short growing seasons of Canada), and desirable fatty acid spectrum (especially gamma-linolenic acid).
But herein lies a problem. The research needed to determine the correct dosage for CBD oil in dogs simply hasn’t been done yet, Coates says. And, to make matters worse, FDA testing has shown that many CBD products contain little if any CBD, she adds. The best option available to pet parents at this time is to talk to a veterinarian who has experience with pets being treated with cannabis oil about proper dosage and reputable manufacturers, Coates says.
An alternative to the gateway hypothesis is the common liability to addiction (CLA) theory. It states that some individuals are, for various reasons, willing to try multiple recreational substances. The "gateway" drugs are merely those that are (usually) available at an earlier age than the harder drugs. Researchers have noted in an extensive review that it is dangerous to present the sequence of events described in gateway "theory" in causative terms as this hinders both research and intervention.[271]
In Europe and Asia, hemp farming has been conducted for millennia. Although most countries ceased growing hemp after the second word war, some didn’t, including France, China, Russia, and Hungary, so that essential knowledge of how to grow and process hemp was maintained. When commercial hemp cultivation resumed in Canada in 1997, many farmers undertook to grow the crop without appreciating its suitability for their situation, or for the hazards of an undeveloped market. Hemp was often grown on farms with marginal incomes in the hopes that it was a savior from a downward financial spiral. The myth that hemp is a wonder crop that can be grown on any soil led some to cultivate on soils with a history of producing poor crops; of course, a poor crop was the result.
