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.
“The political implications of that scheduling, from a research perspective, are limiting,” explains Sutton. “To my knowledge, of the thousands of academic and research bodies in the United States and Canada whom would be equipped to perform agricultural or medical research on this unique species, only around 40 have actual research licenses to study the plant in a limited context.”
Since the late 2000s (decade) the southeastern district of Surco[15] has experienced a significant increase in upscale corporate developments in the area comprised by avenues Manuel Holguín, El Derby, El Polo and La Encalada due to lower restrictions to grant construction licences and proximity to residential middle and upper class districts and is set to become, after traditional San Isidro and Miraflores, the new corporate centre of Lima.[16]
In the United Kingdom, cultivation licences are issued by the Home Office under the Misuse of Drugs Act 1971. When grown for nondrug purposes, hemp is referred to as industrial hemp, and a common product is fibre for use in a wide variety of products, as well as the seed for nutritional aspects and for the oil. Feral hemp or ditch weed is usually a naturalized fibre or oilseed strain of Cannabis that has escaped from cultivation and is self-seeding.[91]
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.

Cannabis was known to the ancient Assyrians, who discovered its psychoactive properties through the Iranians.[197] Using it in some religious ceremonies, they called it qunubu (meaning "way to produce smoke"), a probable origin of the modern word "cannabis".[198] The Iranians also introduced cannabis to the Scythians, Thracians and Dacians, whose shamans (the kapnobatai—"those who walk on smoke/clouds") burned cannabis flowers to induce trance.[199] The plant was used in China before 2800 BC, and found therapeutic use in India by 1000 BC, where it was used in food and drink, including bhang.[200][201]
While marijuana cultivation requires ample spacing to reduce the risk of mold or bacteria, hemp can be planted more densely. Most marijuana crops are planted at one (1) plant per four (4) square feet. Hemp plants that are grown for hemp oil are planted at roughly 40 to 60 plants per four (4) square feet. Hemp plants grown for fiber are even more densely planted at a rate of about 100 to 120 plants per four (4) square feet.
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.
• Is there a batch number? You know how you check your raw chicken or bagged lettuce every time there's a recall to make sure the one you bought isn't going to make you sick? You should be able to do that with CBD products too. "This is a huge indicator as to whether they are following good manufacturing practices," says Beatty. "There should be a way to identify this product in case it was improperly made so the company can carry out a recall."

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.
In 1924, Russian botanist D.E. Janichevsky concluded that ruderal Cannabis in central Russia is either a variety of C. sativa or a separate species, and proposed C. sativa L. var. ruderalis Janisch, and Cannabis ruderalis Janisch, as alternative names.[48] In 1929, renowned plant explorer Nikolai Vavilov assigned wild or feral populations of Cannabis in Afghanistan to C. indica Lam. var. kafiristanica Vav., and ruderal populations in Europe to C. sativa L. var. spontanea Vav.[53][62] In 1940, Russian botanists Serebriakova and Sizov proposed a complex classification in which they also recognized C. sativa and C. indica as separate species. Within C. sativa they recognized two subspecies: C. sativa L. subsp. culta Serebr. (consisting of cultivated plants), and C. sativa L. subsp. spontanea (Vav.) Serebr. (consisting of wild or feral plants). Serebriakova and Sizov split the two C. sativa subspecies into 13 varieties, including four distinct groups within subspecies culta. However, they did not divide C. indica into subspecies or varieties.[48][64]
Because CBD oil products are mostly unregulated, there’s no guarantee that any given product contains a safe or effective level of CBD. In fact, a study published in the Journal of the American Medical Association in 2017 found that nearly 70 percent of all CBD products sold online are incorrectly labeled, and could cause serious harm to consumers. Some CBD oils may also contain incorrectly labeled amounts of THC and other compounds.
Hemp does best on a loose, well-aerated loam soil with high fertility and abundant organic matter. Well-drained clay soils can be used, but poorly-drained clay soils are very inappropriate because of their susceptibility to compaction, which is not tolerated. Young plants are sensitive to wet or flooded soils, so that hemp must have porous, friable, well-drained soils. Sandy soils will grow good hemp, provided that adequate irrigation and fertilization are provided, but doing so generally makes production uneconomical. Seedbed preparation requires considerable effort. Fall plowing is recommended, followed by careful preparation of a seedbed in the spring. The seedbed should be fine, level, and firm. Seed is best planted at 2–3 cm (twice as deep will be tolerated). Although the seedlings will germinate and survive at temperatures just above freezing, soil temperatures of 8°–10°C are preferable. Generally hemp should be planted after danger of hard freezes, and slightly before the planting date of maize. Good soil moisture is necessary for seed germination, and plenty of rainfall is needed for good growth, especially during the first 6 weeks. Seeding rate is specific to each variety, and this information should be sought from the supplier. Fiber strains are typically sown at a minimum rate of 250 seeds per m2 (approximately 45 kg/ha), and up to three times this density is sometimes recommended. In western Europe, seeding rates range from 60–70 kg/ha for fiber cultivars. Recommendations for seeding rates for grain production vary widely, from 10–45 kg/ha. Densities for seed production for tall, European, dual-purpose cultivars are less than for short oilseed cultivars. Low plant densities, as commonly found in growing tall European cultivars for seed, may not suppress weed growth adequately, and under these circumstances resort to herbicides may pose a problem for those wishing to grow hempseed organically. Hemp requires about the same fertility as a high-yielding crop of wheat. Industrial hemp grows well in areas that corn produces high yields. Growing hemp may require addition of up to 110 kg/ha of nitrogen, and 40–90 kg/ha of potash. Hemp particularly requires good nitrogen fertilization, more so for seed production than fiber. Adding nitrogen when it is not necessary is deleterious to fiber production, so that knowledge of the fertility of soils being used is very important. Organic matter is preferably over 3.5%, phosphorus should be medium to high (>40 ppm), potassium should be medium to high (>250 ppm), sulfur good (>5,000 ppm), and calcium not in excess (<6,000 ppm).
within 3 days of using both the oil and this cream-no more knee and hip pain. Years and years of pain. Ive tried every pain rub on the market and a few homemade brews too. Had my nerdy girlfriend , the Doctor look at the ingredients and she was super impressed with the addition of Squalane which means it actually penetrates the skin, something molecules... blah blah blah. Im hooked !
We're on the edge of a CBD explosion. The U.S. market for CBD products is estimated to be worth $2.1 billion by 2020, up 700 percent from 2016; the World Anti-Doping Agency removed CBD from its list of banned substances; the Food and Drug Administration approved an epilepsy medication containing CBD oil for the first time, causing the U.S. Drug Enforcement Administration to shift its stance — albeit very slightly — on CBD.

Our bodies are thought to produce endocannabinoids by the billions every day. “We always thought the ‘runner’s high’ was due to the release of dopamine and endorphins. But now we know the euphoria is also from an endocannabinoid called anandamide,” its name derived from the Sanskrit word for bliss, says Joseph Maroon, M.D., clinical professor and vice chairman of neurosurgery at the University of Pittsburgh Medical Center. We produce these natural chemicals all day, but they fade quickly because enzymes pop up to destroy them. That’s where CBD comes in: By blocking these enzymes, CBD allows the beneficial compounds to linger. This is why Amanda Oliver, 31, a career consultant in Charleston, SC, pops a CBD gummy bear each night before bed. “I used to lie there tossing and turning as my mind raced from work projects to whether I had set the home alarm,” Oliver says. One piece of candy with 15 mg of CBD is enough to shut off her brain and facilitate sleep. She also swears by the CBD oil she takes at the height of her period, which she says quells her debilitating cramps.
AC/DC: A Sativa-dominant phenotype of Cannatonic, this cultivar boasts one of the highest ratios of CBD to THC, clocking in at 20:1. AC/DC is claimed to help reduce pain, anxiety, depression and migraines while reducing symptoms in patients with epilepsy, some forms of cancer, and multiple sclerosis. This cultivar’s pinene-rich terpene profile offers potent clear-headed pain relief.
My Wife had Polio at age 5 and the lingering damage to the L leg and muscle drove her crazy. At age 21 she was using heavy doses of muscle relaxers and pain meds. Needed to bomb herself at night to get some sleep. A Post polio group in West Palm Beach told her about Marijuana and she got some from the Jamaican health aide that was her constant helper. After 5 months she quit all meds. All of them. Slowly came out of the drugged state the meds had caused from 15 years of use. We separated good friends and I know she has gone back to school and getting a degree. All from the help of a plant from Jamaica. I never understood the statement this plant has no viable medical value. Something smells in the politics of this prohibition. Shame.
CBD edibles are usually found in something sweet, like CBD gummies, or CBD cake pops. There's also delicious CBD honey that can be put on food or mixed with hot tea.  It's a simple way to take the CBD you need to help you through the day. Just one or two CBD gummies can give you the CBD you need to put you back on track. For those looking for something a bit simpler, there are also CBD capsules.
It’s thought that CBD might affect your health by attaching to receptors in the body’s endocannabinoid system—a complex biological system involved in maintaining certain aspects of your health. Emerging research shows that endocannabinoids may play a role in regulating such functions as memory, sleep, and mood, as well as metabolic processes like energy balance.

CBD Isolate is the purest supplement available. It’s a 99% pure CBD supplement derived from hemp oil. Despite its concentration, CBD isolate effects are similar to other CBD concentrates, and it can be used in a variety of ways. It can be consumed itself, added to foods and beverages, or vaporized. You can also add it to other CBD products to increase their potency.
Will hemp commercial cultivation resume in the US in the foreseeable future? This is difficult to judge, but the following considerations suggest this might occur: (1) increasing awareness of the differences between industrial hemp and marijuana; (2) growing appreciation of the environmental benefits of hemp cultivation; (3) continuing demonstration of successful hemp cultivation and development in most of the remaining western world; all the G8 countries, except the US, produce and export industrial hemp; and (4) increasing pressure on state and federal governments to permit hemp cultivation by farmers, particularly wheat, corn, and tobacco farmers in desperate need of substitute crops, but also for rotation crops to break pest and disease cycles.

• What's the dosing? This is a confusing one for many people. "A lot of brands don't do a good job of clearly instructing their consumer on the dosing," says Chris Roth, CEO and co-founder of Highline Wellness. When thinking about dosing, also consider whether your CBD is full-spectrum or isolate: Full-spectrum could include other cannabinoids like cannabidivarin or cannabigerol (this is important, since "there's something called the 'entourage effect' when all together, they're more effective than any one of them alone," Roth explains), while isolate is 100% CBD. "Some people might only need 10 milligrams of full-spectrum CBD, but with isolate, even taking 80 or 100 milligrams might not have the same effect," he says.
Pharmacologic effects of inhaled marijuana occur within minutes but rarely persist longer than 2 to 3 hours. The likelihood that an acutely intoxicated patient would come to the operating room is small. Severe tachycardia should be controlled preoperatively with labetalol or esmolol. Animal studies have demonstrated decreased dose requirements for volatile anesthetics, barbiturates, and ketamine after the intravenous injection of THC. Possible intraoperative complications include bronchospasm secondary to airway irritability by the marijuana smoke, although marijuana is a bronchodilator.
Cannabis most likely originates from Central Asia, as archeological evidence indicates that it was already cultivated in China for food and fiber 10 000 years ago. Even in ancient Egyptian mummies, clues have been found for the use of Cannabis as food or medicine.25 In fact, Cannabis is one of the oldest known medicinal plants and is described in almost every ancient handbook on plant medicine, most commonly in the form of a tincture or a tea.26,27 Some religions were closely related with the properties of the Cannabis plant. For example, in Hindu legend, Cannabis is believed to be the favorite food of the god Shiva, because of its energizing properties. As Cannabis spread from Asia toward the West, almost every culture came into contact with this miracle plant. Nowadays, varieties of Cannabis can be found in all temperate and tropical zones, except in humid, tropical rain forests.28
The term hemp is used to name the durable soft fiber from the Cannabis plant stem (stalk). Cannabis sativa cultivars are used for fibers due to their long stems; Sativa varieties may grow more than six metres tall. However, hemp can refer to any industrial or foodstuff product that is not intended for use as a drug. Many countries regulate limits for psychoactive compound (THC) concentrations in products labeled as hemp.
“We continue to see great progress towards a new perspective on cannabis within the US. Within healthcare, several conditions and certain patient profiles rely heavily on CBD-only products of which the proposed Farm Bill will work to dramatically improve access to patients – not only in the US but globally,” said Prad Sekar, CEO of CB2 Insights in a written interview.
Running a profitable and legal cannabis dispensary is entirely possible but not at all easy. The regulatory labrynth is tough to navigate, startup costs are usually significant, the taxes are brutal and the competition is fierce. Building a successful cannabis business means understanding, before you even get started, the many ways this industry is unique.
Hemp is a farmer's friend because compared with cotton, corn, and soybeans, it requires little water, isn't picky when it comes to poor soil. It grows tightly spaced, thus crowding out weeds, and boasts a deep, soil-aerating root system. Despite all its advantages, and because growing it is illegal with the exception of limited licenses, the U.S. imports approximately $60 million worth of hemp from overseas countries like China.
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).
Sean McAllister, one of the researchers at California Pacific, was studying the effects of Cannabidiol(CBD). Pierre Desprez, a molecular biologist researcher, began studying ID-1, the gene that causes cancer to spread, about 20 years ago. The two combined their research and introduced CBD to cancer cells containing ID-1 in a petri dish. They found that CBD stopped the metastasis of the cancer cells.
In terms of sleep, it stands to reason that a less anxious animal is going to be more ready to fall asleep than a hyper-vigilant one. Additionally, though, there’s evidence that CBD, in its interaction with the endocannabinoid system, can help establish and maintain a healthy sleep/wake cycle — which is what tells both humans and animals when to feel sleepy and when to be awake.
In a double-blind, placebo-controlled study, 24 smokers were randomly chosen to receive either an inhaler of CBD oil or a placebo. Participants were asked to take a puff every time they had an urge to puff a cigarette. Over the week, those with placebo inhalers saw no change in their total number of cigarettes consumed, while those who were taking CBD saw a nearly 40 percent drop in their intake. Using the inhaler decreased the number of cigarettes without increasing their craving for nicotine, pointing towards a purpose for Cannabidiol in the withdrawal process.
Keep in mind that CBD levels may vary from crop to crop—even from plant to plant. However, below are some strains that have been bred to contain higher CBD levels, so they might be a good place to start. Check the map on their strain page to see if these are sold at a dispensary near you. We also recommend checking with dispensaries about the specifics of their strains’ CBD levels. It’s always a good idea to purchase only lab-tested products that clearly state the CBD/THC levels so you know what kind of experience to expect.
