“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.
CBD is a 5-HT1A receptor agonist, which may also contribute to an anxiolytic effect. This likely means the high concentrations of CBD found in Cannabis indica mitigate the anxiogenic effect of THC significantly. The cannabis industry claims that sativa strains provide a more stimulating psychoactive high while indica strains are more sedating with a body high. However this is disputed by researchers.
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.
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.

In February 2019, I had been shipped two items and double charged and it is such a process. I wish I could have been that loyal customer and was really committed, but don't beat around the bush telling me things and then wonder why I'm frustrated, I can get a refund, or have to pay shipping when they can foot the bill. Maybe it wasn't meant to be, but I'm with another company and things did get fuzzy, but they took care of me every time, and if a company is willing to foot you the shipping cost over your loyalty, what does that say? I'm just trying to challenge you the reader.
And without high-quality trials, experts don’t know how much is best for a given purpose. The staff at Roth’s dispensary told her, “Try some once or twice a day and see what happens.” (Half a dropper’s worth was a good amount for her.) One thing scientists feel confident about is that CBD is not dangerous. It won’t damage vital organs even at doses as high as 5,000 mg a day, Marcu says, and nobody has died from simply overdosing on a cannabis product.
Hemp can be used as a "mop crop" to clear impurities out of wastewater, such as sewage effluent, excessive phosphorus from chicken litter, or other unwanted substances or chemicals. Additionally, hemp is being used to clean contaminants at the Chernobyl nuclear disaster site, by way of a process which is known as phytoremediation—the process of clearing radioisotopes and a variety of other toxins from the soil, water, and air.
CBD Oil is passing Medical Marijuana as the preferred product for the benefits of CBD. In fact it appears to be REPLACING medical marijuana and health professionals agree. Because CBD Oil is rich in CBD and has Zero THC, the benefits of CBD are prevalent, while the impairment of THC is nonexistent. When chosing CBD oil, look for our HempWorx 750 cbd dominant oil, as referred to above.
From 1982 to 2002 the EU provided the equivalent of about 50 million dollars to develop new flax and hemp harvesting and fiber processing technologies (Karus et al. 2000). Because of the similarities of flax and hemp, the technologies developed for one usually are adaptable to the other. In addition, various European nations and private firms contributed to the development of hemp technologies. Accordingly, Europe is far more advanced in hemp development with respect to all fiber-based applications than other parts of the world. The EU currently dedicates about 30,000 ha to hemp production. France is the leading country in hemp cultivation in the EU, and 95% of the non-seed production is used for “specialty pulp” as described below. Harvesting and processing machinery for fiber hemp is highly advanced in Europe, and some has been imported into Canada. However, there is insufficient fiber processing capacity to handle hemp produced in Canada.
There are two main compounds found in cannabis: THC and CBD. Both are very effective in managing pain. THC gives us that familiar “high,” while CBD does not. For instance, medicinal CBD oil contains small amounts of THC, so users get all of the benefits of cannabis without altering their state of mind. A Canadian study found no serious side effects of medical cannabis after one year of pain treatment.
In support of the previous study by Power et al. (in press), a second study by Giordano, Ohlsoon, Sundquist, Sundquist, and Kendler (2015) found that the relationship between cannabis use or abuse and schizophrenia may not be as strong as believed. The authors found that as the degree of shared genetic and environmental factors increased (beginning with first cousins to full siblings), the relationship between schizophrenia and cannabis abuse decreased, although it remained significant even in full sibling pairs.
The scientific debate regarding taxonomy has had little effect on the terminology in widespread use among cultivators and users of drug-type Cannabis. Cannabis aficionados recognize three distinct types based on such factors as morphology, native range, aroma, and subjective psychoactive characteristics. Sativa is the most widespread variety, which is usually tall, laxly branched, and found in warm lowland regions. Indica designates shorter, bushier plants adapted to cooler climates and highland environments. Ruderalis is the informal name for the short plants that grow wild in Europe and Central Asia.
One claim is that Hearst believed[dubious – discuss] that his extensive timber holdings were threatened by the invention of the decorticator which he feared would allow hemp to become a cheap substitute for the paper pulp used for newspaper. Historical research indicates this fear was unfounded because improvements of the decorticators in the 1930s – machines that separated the fibers from the hemp stem – could not make hemp fiber a cheaper substitute for fibers from other sources. Further, decorticators did not perform satisfactorily in commercial production.

Lisa Hamilton, a jeweler and doula in Brooklyn, NY, knows about the side effects. She recently tried CBD for the shoulder pain that plagued her five years after an accident. Her doctor certified that she was in chronic pain, which under New York State law allowed her to buy from a state dispensary. One Friday, she swallowed two 10-mg capsules, the amount recommended at the dispensary, then took another two on Saturday. “By Sunday, it felt like I’d gotten hit by a truck. Every muscle and joint ached,” Hamilton says. She cut back to one pill a day the following week, but still felt hungover. She stopped after that.
Hemp seeds have an attractive nutty taste, and are now incorporated into many food preparations (Fig. 34), often mimicking familiar foods. Those sold in North America include nutritional (granola-type) or snack bars, “nut butters” and other spreads, bread, pretzels, cookies, yogurts, pancakes, porridge, fruit crumble, frozen dessert (“ice cream”), pasta, burgers, pizza, salt substitute, salad dressings, mayonnaise, “cheese,” and beverages (“milk,” “lemonade,” “beer,” “wine,” “coffee nog”). Hemp seed is often found canned or vacuum-packed (Fig. 35). Alcoholic beverages made with hemp utilize hempseed as a flavorant. Hemp food products currently have a niche market, based particularly on natural food and specialty food outlets.
Since then, many different types of sex determination systems have been discovered, particularly in plants. Dioecy is relatively uncommon in the plant kingdom, and a very low percentage of dioecious plant species have been determined to use the XY system. In most cases where the XY system is found it is believed to have evolved recently and independently.
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.
Exactly how and when hemp originated in the New World is still highly debated. Though long thought to be introduced to the Americas by Christopher Columbus, hemp has been discovered in Native American civilizations that predate Columbus’ arrival. William Henry Holmes’ “Prehistoric Textile Art of Eastern United States” report from 1896 notes hemp from Native American tribes of the Great Lakes and Mississippi Valley. Hemp products from pre-Columbian native civilizations were also found in Virginia. Vikings, who depended on hemp for making rope and sails, may also have brought hemp seeds with them when they attempted to colonize the New World.
Medical cannabis (or medical marijuana) refers to the use of cannabis and its constituent cannabinoids, to treat disease or improve symptoms. Cannabis is used to reduce nausea and vomiting during chemotherapy, to improve appetite in people with HIV/AIDS, and to treat chronic pain and muscle spasms. Cannabinoids are under preliminary research for their potential to affect stroke.
There are many ways to prepare cannabis for consumption. And while final marijuana products may come in many forms, each aims to provide rich concentrations of the terpenes, cannabinoids, and other desirable compounds the marijuana plant produces. From the simple process of drying and curing marijuana flowers, to the sophisticated chemistry of producing cannabis concentrates, here’s a guide to the most common forms of cannabis.
I did like the products at first. After 3 months the product seemed to stop working. There always seems to be shipping issues. Don't get me started on how annoying the representatives that sell this are or the company itself with their numerous emails sent on a daily basis. They seem to care more about getting people to sell their product then to use their product. I would not recommend.
Yes, with some caveats. CBD and CBDa is legal in most states of the United States as long as it comes along with no more than 0.03% thc. CBD all by itself, is pretty much legal everywhere. However, you could still run into legal problems if you have a cop or court which is hell-bent on charging people with violation of marijuana laws or even laws about where you can buy non-psychoactive hemp. This is rare but has happened on occasion.
Focusing more on lifestyle issues and their relationships with functional health, data from the Alameda County Study suggested that people can improve their health via exercise, enough sleep, maintaining a healthy body weight, limiting alcohol use, and avoiding smoking. Health and illness can co-exist, as even people with multiple chronic diseases or terminal illnesses can consider themselves healthy.
Only since the flower-power-time of the 1960s, the smoking of Cannabis as a recreational drug has become a widely known phenomenon in the Western world. From then on, import of stronger varieties from the tropics, combined with a growing expertise in breeding and cultivation, led to a steady increase in psychoactive potency. Contemporary recreational Cannabis has increasingly become a high-tech crop, grown indoors under completely artificial conditions.
μ-Opioid receptor agonists (opioids) (e.g., morphine, heroin, hydrocodone, oxycodone, opium, kratom) α2δ subunit-containing voltage-dependent calcium channels blockers (gabapentinoids) (e.g., gabapentin, pregabalin, phenibut) AMPA receptor antagonists (e.g., perampanel) CB1 receptor agonists (cannabinoids) (e.g., THC, cannabis) Dopamine receptor agonists (e.g., levodopa) Dopamine releasing agents (e.g., amphetamine, methamphetamine, MDMA, mephedrone) Dopamine reuptake inhibitors (e.g., cocaine, methylphenidate) GABAA receptor positive allosteric modulators (e.g., barbiturates, benzodiazepines, carbamates, ethanol (alcohol) (alcoholic drink), inhalants, nonbenzodiazepines, quinazolinones) GHB (sodium oxybate) and analogues Glucocorticoids (corticosteroids) (e.g., dexamethasone, prednisone) nACh receptor agonists (e.g., nicotine, tobacco, arecoline, areca nut) Nitric oxide prodrugs (e.g., alkyl nitrites (poppers)) NMDA receptor antagonists (e.g., DXM, ketamine, methoxetamine, nitrous oxide, phencyclidine, inhalants) Orexin receptor antagonists (e.g., suvorexant)
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.
Cannabis has mental and physical effects, such as creating a "high" or "stoned" feeling, a general change in perception, heightened mood, and an increase in appetite. Onset of effects is within minutes when smoked, and about 30 to 60 minutes when cooked and eaten. They last for between two and six hours. Short-term side effects may include a decrease in short-term memory, dry mouth, impaired motor skills, red eyes, and feelings of paranoia or anxiety. Long-term side effects may include addiction, decreased mental ability in those who started as teenagers, and behavioral problems in children whose mothers used cannabis during pregnancy. There is a strong relation between cannabis use and the risk of psychosis, though the cause-and-effect is debated.
Foreign sources, China in particular, can produce hemp seed cheaply, but imported seed must be sterilized, and the delays this usually requires are detrimental. Seed that has been sterilized tends to go rancid quickly, and so it is imperative that fresh seed be available, a great advantage for domestic production. An additional extremely significant advantage that domestic producers have over foreign sources is organic production, which is important for the image desired by the hemp food market. Organic certification is much more reliable in North America than in the foreign countries that offer cheap seeds. Whereas China used to supply most of the hempseed used for food in North America, Canadian-grown seeds have taken over this market.
The shape and type of a CBD almost always closely reflect the city's history. Cities with strong preservation laws and maximum building height restrictions to retain the character of the historic and cultural core will have a CBD quite a distance from the centre of the city. This is quite common for European cities such as Paris or Vienna. In cities in the New World that grew quickly after the invention of mechanised modes such as road or rail transport, a single central area or downtown will often contain most of the region's tallest buildings and act both as the CBD and the commercial and cultural city center. Increasing urbanisation in the 21st century have developed megacities, particularly in Asia, that will often have multiple CBDs scattered across the urban area. It has been said that downtowns (as understood in North America) are therefore conceptually distinct from both CBDs and city centers. No two CBDs look alike in terms of their spatial shape, however certain geometric patterns in these areas are recurring throughout many cities due to the nature of centralised commercial and industrial activities.
Indoor marijuana grows provide the most control over growing conditions. With a simple setup including a tent, proper lighting, and an air circulation system, home marijuana growers can produce consistent yields. Both soil and hydro systems can be utilized for indoor marijuana grows. Soil setups are generally cheaper and more forgiving, but hydro systems tend to be more common.
We went back and forth like that for several rounds, yelling at each other in 30-degree weather in front of an RV wrapped in marijuana-leaf graphics and blasting Bob Marley music. Finally, he stopped trying to enlighten me and shuffled off to let me buy my lollies in peace. As I tore into my new treats, I realized the whole thing had been a scene from the internet’s dominant cannabidiol discourse come to life: Some money had been spent and some opinions had been said, but no one had gained any information.
Although the environmental and biodiversity benefits of growing hemp have been greatly exaggerated in the popular press, C. sativa is nevertheless exceptionally suitable for organic agriculture, and is remarkably less “ecotoxic” in comparison to most other crops (Montford and Small 1999b). Figure 50 presents a comparison of the ecological friendliness of Cannabis crops (fiber, oilseed, and narcotics) and 21 of the world’s major crops, based on 26 criteria used by Montford and Small (1999a) to compare the ecological friendliness of crops.
In Canada, the methodology used for analyses and sample collection for THC analysis of hemp plantings is standardized (at the Health Canada/Therapeutics Program/Hemp web site at www.hc-sc.gc.ca/hpb-dgps/therapeut/htmleng/hemp.html, see “Industrial Hemp Technical Manual” for procedures on sampling plant materials and chemical procedures for determining THC levels). The regulations require that one of the dozen independent laboratories licensed for the purpose conduct the analyses and report the results to Health Canada. Sample collection is also normally carried out by an independent authorized firm. The Canadian system of monitoring THC content has rigidly limited hemp cultivation to cultivars that consistently develop THC levels below 0.3%.
