A rather thorough analysis of the scope of the illicit marijuana industry in Canada for 1998 is reported at www.rcmp-grc.gc.ca/html/drugsituation.htm#Marihuana and summarized in MacLeod (1999). At least 800 tonnes (t) of marijuana were grown in Canada in 1998, representing a harvest of 4.7 million flowering plants. More than 50% of the marijuana available in Canada is grown domestically. An average mature plant was estimated to produce 170 g of “marketable substance.” The value of the Canadian crop is uncertain, but has been estimated to be in the billions of dollars annually (Heading 1998; MacLeod 1999).

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]
In the mid 1990s, the EU provided subsidization for hemp cultivation of ca. $1,050/ha. This support was instrumental in developing a hemp industry in western Europe. However, no comparable support is available in North America, and indeed those contemplating entering into hemp cultivation are faced with extraordinary costs and/or requirements in connection with licensing, security, THC analysis, and record keeping. Those involved in value-added processing and distribution are also faced with legal uncertainties and the regular threat of idiosyncratic, indeed irrational actions of various governments. Simply displaying a C. sativa leaf on advertising has led to the threat of criminal charges in the last decade in several G8 countries. Attempting to export or import hemp products among countries is presently a most uncertain activity.
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.
This pocket-sized salve is perfect for travel or for sports, when you need a quick fix for your sore joints and muscles. It is also infused with arnica, meadowsweet, elderflower, calendula, ginger, vitamin E, turmeric, and other nourishing skincare ingredients that provide anti-inflammatory benefits. It’s good to know ahead of time that this salve is extremely hard to apply—there’s a lot of beeswax in there, which makes it difficult to melt enough to rub into your skin. (There is also a handy Topical Roll-On version so that you don’t have to even use your fingers—the problem is, the roll-on formula is also made with beeswax. It’s been 65 degrees in New York City all week and I still can’t get the formula to melt in the roll-on. Nothing that placing the container in a bowl of hot water won’t solve, but it’s not up to general skincare standards.)
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.
CBD can come from both the Cannabis and hemp plant, and knowing the difference is big when selecting an oil. Marijuana-based oils can contain THC often in smaller amounts but ultimately still a toxin to humans and potentially fatal to dogs. Hemp-based are THC free and found more common due to the legality aspects and along with this can be used by pets to cure some of their ailments as well. 
In the United States, cannabis is overall the number four value crop, and is number one or two in many states including California, New York and Florida, averaging $3,000 per pound ($6,600/kg).[256][257] Some believe it generates an estimated $36 billion market.[258] Some have argued that this estimate is methodologically flawed, and makes unrealistic assumptions about the level of marijuana consumption. Other estimates claiming to correct for this flaw claim that the market is between $2.1-$4.3 billion.[249] The United Nations Office on Drugs and Crime claims in its 2008 World Drug Report that typical U.S. retail prices are $10–15 per gram (approximately $280–420 per ounce). Street prices in North America are known to range from about $40–$400 per ounce ($1.4–$14/g), depending on quality.[259]

Hemp plants can be vulnerable to various pathogens, including bacteria, fungi, nematodes, viruses and other miscellaneous pathogens. Such diseases often lead to reduced fiber quality, stunted growth, and death of the plant. These diseases rarely affect the yield of a hemp field, so hemp production is not traditionally dependent on the use of pesticides.
Because these receptors are found in almost every part of our body and essentially regulate our entire well-being. Some of these receptors include the Serotonin receptor (regulates our mood and how we feel), the Adenosine receptor (regulates how we respond to stress), and the Vanilloid receptor (helps regulate pain). The regulation of these receptors alone is vital to not only our well-being but our dogs as well. This is how CBD is able to provide your dog with natural relief to conditions such as:
Hemp is considered by a 1998 study in Environmental Economics to be environmentally friendly due to a decrease of land use and other environmental impacts, indicating a possible decrease of ecological footprint in a US context compared to typical benchmarks.[63] A 2010 study, however, that compared the production of paper specifically from hemp and eucalyptus concluded that "industrial hemp presents higher environmental impacts than eucalyptus paper"; however, the article also highlights that "there is scope for improving industrial hemp paper production".[64] Hemp is also claimed to require few pesticides and no herbicides, and it has been called a carbon negative raw material.[65][66] Results indicate that high yield of hemp may require high total nutrient levels (field plus fertilizer nutrients) similar to a high yielding wheat crop.[67]
Smoking marijuana is hands down the most widely used method of consuming cannabis. It’s also the simplest: a rolling paper and some dried marijuana flower are all you need. Other, more technological methods of smoking marijuana may be rising in popularity. But for many people, the social experience of passing weed around with some friends is what cannabis is all about.
The earliest recorded uses date from the 3rd millennium BC.[32] Since the early 20th century, cannabis has been subject to legal restrictions. The possession, use, and sale of cannabis is illegal in most countries of the world.[33][34] Medical cannabis refers to the physician-recommended use of cannabis, which takes place in Canada, Belgium, Australia, the Netherlands, Germany, Spain, and 33 U.S. states.[35][36] In September 2018, cannabis was legalized in South Africa[37] while Canada legalized recreational use of cannabis in October 2018.[38]

Cement (Concrete) and Plaster. Utilizing the ancient technique of reinforcing clay with straw to produce reinforced bricks for constructing domiciles, plant fibers have found a number of comparable uses in modern times. Hemp fibers added to concrete increase tensile strength while reducing shrinkage and cracking. Whole houses have been made based on hemp fiber (Fig. 24, 25). In North America, such usage has only reached the level of a cottage industry. Fiber-reinforced cement boards and fiber-reinforced plaster are other occasionally produced experimental products. Hemp fibers are produced at much more cost than wood chips and straw from many other crops, so high-end applications requiring high strength seem most appropriate.

Sublingual CBD Oils – also known as CBD Tinctures or CBD Hemp Oil – are the most popular type of CBD products, because of their high bioavailability and rapid absorption. There are many other kinds of products as well, including CBD edibles, CBD topicals, and even CBD-infused Coffee. CBD products have gained immense popularity in health and wellness circles thanks to their natural support of our endocannabinoid system (ECS).
One study comparing the effects of THC and CBD even found that, while THC increased anxiety by activating the neurotransmitters involved in the "fight or flight" response, CBD actually repressed autonomic arousal—or the nervous system response associated with sudden increases in heart rate or respiration. In other words, CBD is ideal for people looking to relax and unwind—not get out of their minds.
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). 

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.

There's plenty of anecdotal evidence that CBD helps treat a variety of ailments. People are turning to oils, gummies, and other CBD food and drink products to relax at the end of a long day. Retired NFL players are using CBD to manage physical pain, debilitating headaches, and sleeplessness. Spa clients are even using CBD skin products to fight signs of aging.
Cannabis, also referred to as marijuana, has been an integral part of human civilizations for millennia. Both as a medicine and as a recreational substance, cannabis is the most popular illicit drug in the world. Today, the legal landscape that has prohibited marijuana for much of the twentieth century is giving way to decriminalization and full legalization. Legal, commercial cannabis businesses are already making an enormous economic impact.
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.
Highly selected forms of the fiber cultigen possess features maximizing fiber production. Since the nodes tend to disrupt the length of the fiber bundles, thereby limiting quality, tall, relatively unbranched plants with long internodes have been selected. Another strategy has been to select stems that are hollow at the internodes, with limited wood, since this maximizes production of fiber in relation to supporting woody tissues. Similarly, limited seed productivity concentrates the plant’s energy into production of fiber, and fiber cultivars often have low genetic propensity for seed output. Selecting monoecious strains overcomes the problem of differential maturation times and quality of male (staminate) and female (pistillate) plants (males mature 1–3 weeks earlier). Male plants in general are taller, albeit slimmer, less robust, and less productive. Except for the troublesome characteristic of dying after anthesis, male traits are favored for fiber production, in contrast to the situation for drug strains noted below. In former, labor-intensive times, the male plants were harvested earlier than the females, to produce superior fiber. The limited branching of fiber cultivars is often compensated for by possession of large leaves with wide leaflets, which obviously increase the photosynthetic ability of the plants. Since fiber plants have not generally been selected for narcotic purposes, the level of intoxicating constituents is usually limited.
They may be safe, but there's one massive problem: There's practically no scientific data to support the idea that a CBD-infused topical cream is any more effective than other topical pain relievers, like Tiger Balm, BenGay, or Icy Hot. Michelle Sexton, a San Diego-based naturopathic doctor and medical research director of the Center for the Study of Cannabis and Social Policy says that her patients do seem to have a great interest in CBD ointments, and roughly 40 percent of them have indeed tried one. However, these people are in her office now because the topicals didn’t work for them. "As a medical professional, my opinion is there’s little evidence to back up the claims being made—it’s all marketing for now," she says.
Fatty Acids. The quality of an oil or fat is most importantly determined by its fatty acid composition. Hemp is of high nutritional quality because it contains high amounts of unsaturated fatty acids, mostly oleic acid (C18:1, 10%–16%), linoleic acid (C18:2, 50%–60%), alpha-linolenic acid (C18:3, 20%–25%), and gamma-linolenic acid (C18:3, 2%–5%) (Fig. 37). Linoleic acid and alpha-linolenic acid are the only two fatty acids that must be ingested and are considered essential to human health (Callaway 1998). In contrast to shorter-chain and more saturated fatty acids, these essential fatty acids do not serve as energy sources, but as raw materials for cell structure and as precursors for biosynthesis for many of the body’s regulatory biochemicals. The essential fatty acids are available in other oils, particularly fish and flaxseed, but these tend to have unpleasant flavors compared to the mellow, slightly nutty flavor of hempseed oil. While the value of unsaturated fats is generally appreciated, it is much less well known that the North American diet is serious nutritionally unbalanced by an excess of linoleic over alpha-linonenic acid. In hempseed, linoleic and alpha-linolenic occur in a ratio of about 3:1, considered optimal in healthy human adipose tissue, and apparently unique among common plant oils (Deferne and Pate 1996). Gamma-linolenic acid or GLA is another significant component of hemp oil (1%–6%, depending on cultivar). GLA is a widely consumed supplement known to affect vital metabolic roles in humans, ranging from control of inflammation and vascular tone to initiation of contractions during childbirth. GLA has been found to alleviate psoriasis, atopic eczema, and mastalgia, and may also benefit cardiovascular, psychiatric, and immunological disorders. Ageing and pathology (diabetes, hypertension, etc.) may impair GLA metabolism, making supplementation desirable. As much as 15% of the human population may benefit from addition of GLA to their diet. At present, GLA is available in health food shops and pharmacies primarily as soft gelatin capsules of borage or evening primrose oil, but hemp is almost certainly a much more economic source. Although the content of GLA in the seeds is lower, hemp is far easier to cultivate and higher-yielding. It is important to note that hemp is the only current natural food source of GLA, i.e. not requiring the consumption of extracted dietary supplements. There are other fatty acids in small concentrations in hemp seed that have some dietary significance, including stearidonic acid (Callaway et al. 1996) and eicosenoic acid (Mölleken and Theimer 1997). Because of the extremely desirable fatty acid constitution of hemp oil, it is now being marketed as a dietary supplement in capsule form (Fig. 38).
There is concern that cannabis may contribute to cardiovascular disease,[103] but as of 2018, evidence of this relationship was unclear.[104][105] Cannabis is believed to be an aggravating factor in rare cases of arteritis, a serious condition that in some cases leads to amputation. Because 97% of case-reports also smoked tobacco, a formal association with cannabis could not be made. If cannabis arteritis turns out to be a distinct clinical entity, it might be the consequence of vasoconstrictor activity observed from delta-8-THC and delta-9-THC.[106] Other serious cardiovascular events including myocardial infarction, stroke,[107] sudden cardiac death, and cardiomyopathy have been reported to be temporally associated with cannabis use. Research in these events is complicated because cannabis is often used in conjunction with tobacco, and drugs such as alcohol and cocaine.[108] These putative effects can be taken in context of a wide range of cardiovascular phenomena regulated by the endocannabinoid system and an overall role of cannabis in causing decreased peripheral resistance and increased cardiac output, which potentially could pose a threat to those with cardiovascular disease.[109] There is some evidence from case reports that cannabis use may provoke fatal cardiovascular events in young people who have not been diagnosed with cardiovascular disease.[110] Smoking cannabis has also been shown to increase the risk of myocardial infarction by 4.8 times for the 60 minutes after consumption.[111]
The reason researchers and cannabis companies are interested in alternative ways of producing cannabinoids is that working with the original plant is messy and complicated. First of all, growing the stuff takes a lot of time, water, and energy (if you’re cultivating indoors). Extracting certain cannabinoids from flower is also a hassle. If you’re only after CBD, for example, there’s a chance your extract could be contaminated with THC. This is of particular concern if you want to isolate CBD for use as a medicine—it’s been shown, for instance, to be remarkably effective in treating epilepsy.
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]
“Industrial hemp, along with all strains of cannabis, are decades behind other agricultural crops in terms of improved plant genetics,” said Arcadia Chief Financial Officer Matt Plavan. “With the explosive market growth projected in the industrial hemp and derivative markets, growers will need the very best hemp strains to meet demand, minimize waste, and ensure consistent quality.”

Over the ages, countless innovations have attempted to improve on the basic experience of inhaling the smoke of combusted cannabis. As a result, there are numerous ways to smoke marijuana. The rolling technique is at the root of joints, blunts, and spliffs. On the other hand, glassware and other devices are essential for smoking weed out of a pipe, bong, or bubbler.
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).
There are thousands of unique varieties of hemp. The cultivars used for CBD oil contain significantly higher concentrations of CBD than others. Using these uniquely potent plants, it is possible to extract cannabis oil that contains significant levels of cannabidiol, as well as essential vitamins, minerals, fatty acids, terpenes, flavonoids, and other non-psychoactive cannabinoids.
There are practical, if cruder alternatives to separate the long fiber for high-quality textile production, but in fact such techniques are used mostly for non-textile applications. This involves production of “whole fibers” (i.e. harvesting both the long fibers from the cortex and the shorter fibers from throughout the stem), and technologies that utilize shortened hemp fibers. This approach is currently dominant in western Europe and Canada, and commences with field dew retting (typically 2–3 weeks). A principal limitation is climatic—the local environment should be suitably but not excessively moist at the close of the harvest season. Once stalks are retted, dried, and baled, they are processed to extract the fiber. In traditional hemp processing, the long fiber was separated from the internal woody hurds in two steps, breaking (stalks were crushed under rollers that broke the woody core into short pieces, some of which were separated) and scutching (the remaining hurds, short fibers (“tow”) and long fibers (“line fiber, ” “long-line fiber”) were separated). A single, relatively expensive machine called a decorticator can do these two steps as one. In general in the EU and Canada, fibers are not separated into tow and line fibers, but are left as “whole fiber.” In western Europe, the fiber is often “cottonized,” i.e. chopped into short segments the size of cotton and flax fiber, so that the fibers can be processed on flax processing machinery, which is very much better developed than such machinery is for hemp. In North America the use of hemp for production of even crude textiles is marginal. Accordingly, the chief current fiber usages of North American, indeed of European hemp, are non-textile.
Cannabis use has the hallmark pathologic features shared by all substance use disorders. Like other drugs of abuse, Cannabis causes compulsive drug-seeking behaviors, loss of self-control, withdrawal symptoms, and the propensity to relapse.57 Cannabis use disorder has been recognized as a bona fide disorder and has been included in the most recent version of the Diagnostic and Statistical Manual of Mental Disorders (fifth edition).58 Long-term clinical outcomes for Cannabis use disorder may be less severe than for other drugs of abuse but the addictive processes appears to be very similar. Animal models of addiction have clearly supported the notion that Cannabis has addictive properties.
The seeds are sown with grain drills or other conventional seeding equipment to a depth of 1.27 to 2.54 cm. Greater seeding depths result in increased weed competition. Nitrogen should not be placed with the seed, but phosphate may be tolerated. The soil should have available 89 to 135 kg/ha of nitrogen, 46 kg/ha phosphorus, 67 kg/ha potassium, and 17 kg/ha sulfur. Organic fertilizers such as manure are one of the best methods of weed control.[58]
