Put simply, “indica” strains are those associated with a strong body-high, feelings of sedation and relaxation. For this reason, indicas are often thought of as the “heavier” strains of cannabis, offering stronger highs that impact the whole body. They’re popular among marijuana users as pain relieving and sleep-inducing strains. Indicas are especially popular among medical cannabis patients.
The following sketch of hemp cultivation is insufficient to address all of the practical problems that are encountered by hemp growers. Bócsa and Karus (1998) is the best overall presentation of hemp growing available in English. The reader is warned that this book, as well as almost all of the literature on hemp, is very much more concerned with fiber production than oilseed production. McPartland et al. (2000) is the best presentation available on diseases and pests, which fortunately under most circumstances do limited damage. The resource list presented below should be consulted by those wishing to learn about hemp production. Provincial agronomists in Canada now have experience with hemp, and can make local recommendations. Particularly good web documents are: for Ontario (OMAFRA Hemp Series, several documents): www.gov.on.ca/OMAFRA/english/crops/hort/hemp.html); for Manitoba (several documents): www.gov.mb.ca/agriculture/crops/hemp/bko01s00.html; for British Columbia: (BC Ministry of Agriculture and Foods Fact Sheet on Industrial Hemp, prepared by A. Oliver and H. Joynt): www.agf.gov.bc.ca/croplive/plant/horticult/specialty/specialty.htm
“Geotextiles” or “agricultural textiles” include (1) ground-retaining, biodegradable matting designed to prevent soil erosion, especially to stabilize new plantings while they develop root systems along steep highway banks to prevent soil slippage (Fig. 32); and (2) ground-covers designed to reduce weeds in planting beds (in the manner of plastic mulch). At present the main materials used are polymeric (polythene, spun-blown polypropylene) and some glass fiber and natural fibers. Both woven and non-woven fibers can be applied to geotextiles; woven and knitted materials are stronger and the open structure may be advantageous (e.g. in allowing plants to grow through), but non-wovens are cheaper and better at suppressing weeds. Flax and hemp fibers exposed to water and soil have been claimed to disintegrate rapidly over the course of a few months, which would make them unacceptable for products that need to have long-term stability when exposed to water and oil. Coco (coir) fiber has been said to be much more suitable, due to higher lignin content (40%–50%, compared to 2%–5% in bast fibers); these are much cheaper than flax and hemp fibers (Karus et al. 2000). However, this analysis does not do justice to the developing hemp geotextile market. Production of hemp erosion control mats is continuing in both Europe and Canada. Given the reputation for rot resistance of hemp canvas and rope, it seems probable that ground matting is a legitimate use. Moreover, the ability to last outdoors for many years is frequently undesirable in geotextiles. For example, the widespread current use of plastic netting to reinforce grass sod is quite objectionable, the plastic persisting for many years and interfering with lawn care. Related to geotextile applications is the possibility of using hemp fiber as a planting substrate (biodegradable pots and blocks for plants), and as biodegradable twine to replace plastic ties used to attach plants to supporting poles. Still another consideration is the “green ideal” of producing locally for local needs; by this credo, hemp is preferable in temperate regions to the use of tropical fibers, which need to be imported.

Cannabidiol has been found to act as an antagonist of GPR55, a G protein-coupled receptor and putative cannabinoid receptor that is expressed in the caudate nucleus and putamen in the brain.[31] It has also been found to act as an inverse agonist of GPR3, GPR6, and GPR12.[12] Although currently classified as orphan receptors, these receptors are most closely related phylogenetically to the cannabinoid receptors.[12] In addition to orphan receptors, CBD has been shown to act as a serotonin 5-HT1A receptor partial agonist,[32] and this action may be involved in its antidepressant,[33][34] anxiolytic,[34][35] and neuroprotective effects.[36][37] It is an allosteric modulator of the μ- and δ-opioid receptors as well.[38] The pharmacological effects of CBD have additionally been attributed to PPARγ agonism and intracellular calcium release.[7]
But recent activity in Washington has legislators in every aisle waving banners for hemp. So far, 20 states have stepped up to encourage industrial hemp production.5 On February 7, 2014, the 2013 Farm Bill6 was signed into law, legitimizing industrial hemp as distinct, and authorizing university and State departments of agriculture (where it’s legal) for research or pilot programs. On January 8, 2015, The Industrial Hemp Farming Act of 2015, S. 134, was introduced in the U.S. Senate. 
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.
Fortunately for cannabis-curious pet-owners, the spread of legalization across the country is giving doctors enough resources (nerve) to take research into their own hands. In Colorado, Dr. Stephanie McGrath, a neurologist and assistant professor at Colorado State University's College of Veterinary Medicine & Biomedical Sciences, has completed two clinical studies since 2016 on the effects of cannabidiol in dogs with osteoarthritis or epilepsy. In January, the American Kennel Club granted Dr. McGrath $350,000 for her to begin a three-year crossover study of CBD for epilepsy in dogs. Legislation has been proposed in New York and California that would establish guidelines and allow veterinarians to legally discuss the use of cannabis products with their clients.

The first example of the use of hempcrete was in 1986 in France with the renovation of the Maison de la Turquie in Nogent-sur-Seine by the innovator Charles Rasetti.[30] In the UK hemp lime was first used in 2000 for the construction of two test dwellings in Haverhill.[31] Designed by Modece Architects,[32] who pioneered hemp's use in UK construction, the hemp houses were monitored in comparison with other standard dwellings by BRE. Completed in 2009, the Renewable House is one of the most technologically advanced made from hemp-based materials.[33] The first US home made of hemp-based materials was completed in August 2010 in Asheville, North Carolina.[34]


CBD strains can be consumed just as you would THC strains. You can smoke or vaporize CBD-rich flower, eat a CBD-infused edible, swallow a CBD oil capsule, apply a CBD lotion, or use a CBD tincture sublingually. Hemp products also contain CBD, though it is a less efficient source and lacks the beneficial chemical diversity of cannabis-derived CBD products (more on that here).
I have had chronic pain in my back neuroma in my foot my SI joint. I have had my share of medication. If youve ever had any pain relentless you know what a miserable existence it is. I was at the end of my rope seriously considering cutting off my toe having almost crippling pain from discs and muscles in my back. My husband thought CBD could be a good solution since Id previously had a CBD edible and it helped me through tattoo pain. He went hunting for CBD and just happened to find this lotion. Its been a game changer. I have been able to gain mobility all but erased the pain from my back and has helped me in conjunction with a nerve blocker for my foot. This lotion really does change my life. I call it magic. I am so happy with it.

While it was originally believed that THC is a breakdown product of CBD, it is now known that both THC and CBD are actually metabolites of their decarboxylated acidic forms, THCa and CBDa. These acidic precursors are decarboxylated (essentially dried) by heat or extraction to produce THC and CBD; only then do they become psychoactive.The compound has medicinal benefits without the “high” that some patients do not desire. This makes CBD appealing to patients who are looking for an alternative to their current meds, which often have opiate-like effects.

Know the Warning Signs: As with anything you give to your dog — from chew toys to prescribed medications — it’s important to recognize when something isn’t quite right. If you notice these symptoms in your dog, it might be a good idea to check in with your vet. The following side effects have been reported by humans who took CBD, so do your best to translate them to dogs.
Forskolin is a common name for the plant extract taken from Coleus forskohli. This has been used in Ayurvedic medicines for an assortment of health conditions and ailments. These health conditions, for which is used are asthma, hypertension, psoriasis, congestive health failure, angina, and eczema. The effects of this medical extract have been used in human and animal clinical studies, and most of the in-vitro technology relies mostly on this extract. It works primarily by stimulating various enzymes in the cyclic AMP of cells. Cyclic AMP is one responsible for the most of the essential cell-regulating compounds there is.
The main difference between the two is in its chemical composition, specifically in tetrahydrocannabinol (THC). THC is the chemical responsible marijuana’s psychological effects.An average batch of marijuana contains anywhere from 5-20% THC content. Some premium marijuana can have up to 25-30% THC. Hemp, on the other hand, has a max THC level of 0.3%, essentially making it impossible to feel any psychoactive effect or get a “high”. This threshold is heavily regulated in other countries that have legalized hemp.Hemp also has high cannabidiol (CBD) content that acts as THC’s antagonist, essentially making the minimal amount of THC useless.
Fig. 5. Typical architecture of categories of cultivated Cannabis sativa. Top left: narcotic plants are generally low, highly branched, and grown well-spaced. Top right: plants grown for oilseed were traditionally well-spaced, and the plants developed medium height and strong branching. Bottom left: fiber cultivars are grown at high density, and are unbranched and very tall. Bottom center: “dual purpose” plants are grown at moderate density, tend to be slightly branched and of medium to tall height. Bottom right: some recent oilseed cultivars are grown at moderate density and are short and relatively unbranched. Degree of branching and height are determined both by the density of the plants and their genetic background.
Hemp paper are paper varieties consisting exclusively or to a large extent from pulp obtained from fibers of industrial hemp. The products are mainly specialty papers such as cigarette paper,[41] banknotes and technical filter papers.[42] Compared to wood pulp, hemp pulp offers a four to five times longer fibre, a significantly lower lignin fraction as well as a higher tear resistance and tensile strength. However, production costs are about four times higher than for paper from wood,[43] so hemp paper could not be used for mass applications as printing, writing and packaging paper.
38 states and Puerto Rico considered legislation related to industrial hemp in 2017. These bills ranged from clarifying existing laws to establishing new licensing requirements and programs.  At least 15 states enacted legislation in 2017 — Arkansas, Colorado, Florida, Hawaii, North Dakota, Nevada, New York, Oregon, South Carolina, Tennessee, Virginia, Washington, West Virginia, Wisconsin and Wyoming. At least four states — Florida, Nevada, New Mexico and Wisconsin — authorized new research or pilot programs. 
Despite being chemical cousins, THC and CBD have very different effects. The primary difference is that THC get you high while CBD does not. This is because THC and CBD affect our endocannabinoid system (ECS) in different ways. The major ECS receptor in the brain, CB1, is activated by THC but not CBD. In fact, CBD can get in the way of compounds like THC, preventing them from activating the CB1 receptor. This is why the THC:CBD ratio is so important for influencing the effects of cannabis products.

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.
Would I say that CBD oil has fundamentally changed my life? No. But per the Charlotte's Web website, this is the typical first experience. "Anyone who has ever started a new vitamin or supplement routine knows the short answer to how long it takes to kick in is—'it depends,'" reads the article on what to expect from hemp oil. "For many newcomers, they're not sure what to imagine, or some anticipate a huge change right away. For most of us, though, dietary supplements take time."
Epidiolex is the first FDA-approved treatment in the U.S. that contains a purified drug substance derived from marijuana -- CBD -- and the first treatment for Dravet syndrome. In September 2018 the FDA rescheduled cannabidiol from a C-I controlled substance to a C-V controlled substance, meaning it has a proven medical use but a low risk of abuse. This change allows Epidiolex to be marketed in the U.S.
Some users may experience an episode of acute psychosis, which usually abates after six hours, but in rare instances, heavy users may find the symptoms continuing for many days.[53] A reduced quality of life is associated with heavy cannabis use, although the relationship is inconsistent and weaker than for tobacco and other substances.[54] It is unclear, however, if the relationship is cause and effect.[54]
There are two possible exceptions to this. The first is that some people, for unknown reasons, just react differently to CBD. According to Dr. Chin, about 5% of people say they feel altered after taking CBD. "Usually they're the same people who have side effects from Advil or Tylenol," she says. You never know how your body will react to any new supplement, so when taking CBD for the first time, do so safely under supervision.
Arcadia Biosciences Inc. shares RKDA, +7.63% soared 13.7%, after the food-ingredients and nutritional-oils company said it was granted its first industrial hemp pilot progam license in Hawaii. The license allows Arcadia Specialty Genomics, the company’s cannabis-focused business unit launched last week, to begin research and cultivation of hemp, planted on 10 acres of leased land.
A 2015 meta analysis found that, although a longer period of abstinence was associated with smaller magnitudes of impairment, both retrospective and prospective memory were impaired in cannabis users. The authors concluded that some, but not all, of the deficits associated with cannabis use were reversible.[121] A 2012 meta analyses found that deficits in most domains of cognition persisted beyond the acute period of intoxication, but was not evident in studies where subjects were abstinent for more than 25 days.[122] Few high quality studies have been performed on the long-term effects of cannabis on cognition, and results were generally inconsistent.[123] Furthermore, effect sizes of significant findings were generally small.[122] One review concluded that, although most cognitive faculties were unimpaired by cannabis use, residual deficits occurred in executive functions.[124] Impairments in executive functioning are most consistently found in older populations, which may reflect heavier cannabis exposure, or developmental effects associated with adolescent cannabis use.[125] One review found three prospective cohort studies that examined the relationship between self reported cannabis use and intelligence quotient (IQ). The study following the largest number of heavy cannabis users reported that IQ declined between ages 7–13 and age 38. Poorer school performance and increased incidence of leaving school early were both associated with cannabis use, although a causal relationship was not established.[117] Cannabis users demonstrated increased activity in task-related brain regions, consistent with reduced processing efficiency.[126]
The company's Live Oxygen line includes: The CBD Bio Tech Live Oxygen Cleanser that gentle daily cleanses; The CBD Bio Tech Live Oxygen Toner that hydrates the skin and balances oil, while minimizing pores; The CBD Bio Tech Live Oxygen Facial Lotion that acts like a light daily moisturizer; As well as The CBD Bio Tech Live Oxygen Cream that provides a protective layer over the skin.
Also, you’ll notice in our “Pros” that we indicate that their products are indeed NON-GMO. Just FYI, the use of pesticides isn’t related to whether ingredients are GMO or non-GMO. GMOs (genetically modified organisms) are organisms created in a laboratory using genetic modification/engineering techniques. In the case of King Kanine, the hemp and other ingredients are naturally grown, not genetically modified.
It is for this reason that all the finished hemp goods that you see for sale in America, from food products to clothing to building materials, are part of an imported hemp industry that has surpassed $688 million annually. The size of this import industry is one of the major catalysts for hemp legalization in the U.S. As a renewable source of a range of products, hemp provides an exciting new step in American agriculture.
Cannabis research suggests medical marijuana could become an effective treatment for diabetic neuropathy. Diabetic neuropathy is a debilitating and sometimes fatal condition caused by diabetes. Diabetics suffer from high blood sugar due to insulin resistance, and this damages nerve cells in the body, causing severe pain. Patients who consumed THC as part of a study found they experienced less pain. Findings are not definitive, however, and further research into cannabis as a treatment for diabetes and associated symptoms is required.

All available evidence indicates that long term use of PurCBD+ causes no side effects; however, PurCBD+ has only truly been available for pets for a couple years. The most common reason our customers cite for using CBD is to replace prescription drugs that have a known history of long term side effects. Always consult your veterinarian and use our dosing chart/schedule to coordinate the use of dietary supplements like PurCBD with prescription medications.
Hash oil is a resinous matrix of cannabinoids obtained from the Cannabis plant by solvent extraction,[185] formed into a hardened or viscous mass.[186] Hash oil can be the most potent of the main cannabis products because of its high level of psychoactive compound per its volume, which can vary depending on the plant's mix of essential oils and psychoactive compounds.[187] Butane and supercritical carbon dioxide hash oil have become popular in recent years.[188]
In a study whose findings have not yet been published, he and a colleague, Daniel Friedman, found that patients receiving CBD in addition to their usual medicines had 39 percent fewer convulsive seizures than patients who remained on their normal drug regimen. Given that the study included only the most treatment-resistant patients, this is an “excellent response,” Devinsky says.

A customer of mine knew of my troubles and suggested I try cbd. I was skeptical at first, worried it was just a “fad”. The first time I used my CBD Daily Intesive Cream I was astonished. Minutes after applying to my neck and shoulders I felt relief. For the first time in years I am able to sleep comfortably, work comfortably and get back to heavier workouts that I enjoyed before.

In 2015, almost half of the people in the United States had tried marijuana, 12% had used it in the past year, and 7.3% had used it in the past month.[31] In 2014, daily marijuana use amongst US college students had reached its highest level since records began in 1980, rising from 3.5% in 2007 to 5.9% in 2014 and had surpassed daily cigarette use.[251]

The mosaic of laws that govern CBD legality across the globe varies just as much as the legislation across the US. Generally, CBD extract is legal in most countries, but what makes it illegal is where and what it’s extracted from. Most Group of 20 (G20) countries allow CBD extracted from industrial hemp, but not CBD extracted from whole-plant marijuana. Note, however, the differences between the two. Legislation regarding international travel with CBD also varies among countries. For the foreseeable future, the best practice would be to search online, or contact the respective embassies or consulates, before traveling to determine whether your CBD is safe and legal.
On January 16, 2019, California’s three state cannabis licensing authorities announced that the Office of Administrative Law (OAL) officially approved state regulations for cannabis businesses across the supply chain. Please note, these new cannabis regulations listed below take effect immediately, meaning the previous emergency regulations are no longer in effect.
In addition to acting on the brain, CBD influences many body processes. That’s due to the endocannabinoid system (ECS), which was discovered in the 1990s, after scientists started investigating why pot produces a high. Although much less well-known than the cardiovascular, reproductive, and respiratory systems, the ECS is critical. “The ECS helps us eat, sleep, relax, forget what we don’t need to remember, and protect our bodies from harm,” Marcu says. There are more ECS receptors in the brain than there are for opioids or serotonin, plus others in the intestines, liver, pancreas, ovaries, bone cells, and elsewhere.
CBD could prove to be a life-improving medication for dogs, but without the backing of clinical research to establish its effectiveness and dosing, it’s hard to know for sure. That research is hindered by cannabis’s federal Schedule 1 drug classification, which puts traditional academic research institutions in a legally ambiguous position. It also makes funding harder to come by; much of the work currently underway is sponsored by companies who produce CBD products.
Because of its cloudy classification and constantly-shifting political winds, CBD creates a legal quagmire for anybody who wants to study or recommend its effectiveness as a medicine for animals. To date, there have been no rigorous scientific studies published on marijuana, or even the non-psychoactive CBD, as a treatment for pets with arthritis, seizures, anxiety, or any other medical conditions. But that may soon (hopefully) be changing, as a few studies are either in the planning stages or underway. 
In addition to providing useful fibers, hemp seed also has high nutritional value. and the plant can be used to make biodegradable plastics, some fuels, and a variety of other things. Hemp foods including but not limited to hemp energy bars, hemp salad dressing,hemp milk, hemp protein shakes, hemp oil gel caps and hemp protein powder are among some of the health products being produced today.

Hemp includes all varieties of the Cannabis genus that contain negligible amounts of THC, the chemical that makes marijuana psychoactive and gets you “high”.  The Cannabis family has several different breeds, yet it is most infamously known for marijuana (“weed”). This is the main reason why people confuse the term hemp with marijuana. Hemp actually refers to the industrial, non-drug variant that is cultivated for its fiber, hurd, and seeds.
Research suggests that CBD may exert some of its pharmacological action through its inhibition of fatty acid amide hydrolase (FAAH), which may in turn increase the levels of endocannabinoids, such as anandamide, produced by the body.[7] It has also been speculated that some of the metabolites of CBD have pharmacological effects that contribute to the biological activity of CBD.[39]

Toronto, Ontario--(Newsfile Corp. - February 28, 2019) - Gunpowder Capital Corp., (CSE: GPC), (CSE: GPC.PR.A), (OTCQB: GNPWF), (FSE: YS6N), ("Gunpowder" or the "Corporation") is very pleased to announce that it has entered into a strategic relationship with Hemp Inc., (OTC Pink: HEMP) of Las Vegas Nevada with the purpose of entering into the Industrial Hemp industry in the United States.Under the terms of the agreement, Hemp Inc., and Gunpowder will both make strategic ...
In the United States, non-FDA approved CBD products are classified as Schedule I drugs under the Controlled Substances Act.[62] This means that production, distribution, and possession of non-FDA approved CBD products is illegal under federal law. In addition, in 2016 the Drug Enforcement Administration added "marijuana extracts" to the list of Schedule I drugs, which it defined as "an extract containing one or more cannabinoids that has been derived from any plant of the genus Cannabis, other than the separated resin (whether crude or purified) obtained from the plant."[63] Previously, CBD had simply been considered "marijuana", which is a Schedule I drug.[62][64]
Epidiolex is the first FDA-approved treatment in the U.S. that contains a purified drug substance derived from marijuana -- CBD -- and the first treatment for Dravet syndrome. In September 2018 the FDA rescheduled cannabidiol from a C-I controlled substance to a C-V controlled substance, meaning it has a proven medical use but a low risk of abuse. This change allows Epidiolex to be marketed in the U.S.
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.
Market considerations also heavily determine the wisdom of investing in hemp. Growing hemp unfortunately has a magnetic attraction to many, so there is danger of overproduction. A marketing board could be useful to prevent unrestrained competition and price fluctuations, but is difficult to establish when the industry is still very small. As noted above, unwise investment in Canada produced a glut of seeds that resulted in price dumping and unprofitable levels for the majority. Cultural and production costs of hemp have been said to be comparable to those for corn, and while the truth of this remains to be confirmed, the legislative burden that accompanies hemp puts the crop at a unique disadvantage. Among the problems that Canadian farmers have faced are the challenge of government licensing (some delays, and a large learning curve), very expensive and sometime poor seed (farmers are not allowed to generate their own seed), teenagers raiding fields in the mistaken belief that marijuana is being grown, and great difficulties in exportation because of the necessity of convincing authorities that hemp is not a narcotic. Unless the producer participates in sharing of value-added income, large profits are unlikely. The industry widely recognizes that value added to the crop is the chief potential source of profit, as indeed for most other crops.
Hemp seeds contain virtually no THC, but THC contamination results from contact of the seeds with the resin secreted by the epidermal glands on the leaves and floral parts, and also by the failure to sift away all of the bracts (which have the highest concentration of THC of any parts of the plant) that cover the seeds. This results in small levels of THC appearing in hempseed oil and foods made with the seeds. Although most of the western hemp-growing world uses 0.3% THC as a maximum concentration for authorized cultivation of hemp plants, regulations in various countries allow only a much lower level of THC in human food products manufactured from the seeds. Currently, up to 10 ppm THC is permitted in seeds and oil products used for food purposes in Canada. In Germany, more stringent limits were set for food in 2000: 5 ppm in food oil, 0.005 ppm in beverages, and 0.15 ppm in all other foods. The US Drug Enforcement Administration published new regulations on hemp in the Federal Register on October 9th 2001 that in effect 4 months later would ban the food use of hemp in the US because any amount of THC would be unacceptable in foods (follow links at www.hempreport.com/). These proposals are currently being challenged by the hemp industry. Limits have been set because of concerns about possible toxicity and interference with drug tests (Grotenhermen et al. 1998). An extensive analysis of literature dealing with the toxicity of hemp is in Orr and Starodub (1999; see Geiwitz 2001 for an analysis). Because hemp food products are considered to have great economic potential, there is considerable pressure on the hemp industry in North America to reduce THC levels.
