A limited number of studies have examined the effects of cannabis smoking on the respiratory system.[85] Chronic heavy marijuana smoking is associated with coughing, production of sputum, wheezing, and other symptoms of chronic bronchitis.[68] The available evidence does not support a causal relationship between cannabis use and chronic obstructive pulmonary disease.[86] Short-term use of cannabis is associated with bronchodilation.[87]
The importation and movement of hemp seeds and plants is restricted under federal law. According to the Statement of Principles on Industrial Hemp (81 Federal Register (FR) 53395) issued by the U.S. Department of Agriculture, U.S. Drug Enforcement Administration, and U.S. Food and Drug Administration, "industrial hemp plants and seeds may not be transported across State lines." For more information, contact the U.S. Drug Enforcement Administration.
Also high in fiber, hemp seeds are more digestible than any other high-protein food, including meat, cheese, eggs, human milk, or cows’ milk. They’re high in antioxidants, and minerals like iron, zinc and copper as well as calcium, magnesium, potassium, carotene, thiamin (vitamin B1), riboflavin (vitamin B2), vitamin B6 and vitamin E. If that’s not enough, there’s also chlorophyll, sulfur, phosphorus, phospholipids, and phytosterols.
Hemp, the non-psychoactive variety of the cannabis sativa plant, is already being integrated into several mature markets such as food, textiles, construction, personal care and nutraceuticals. This relatively quiet cannabis relative is emerging as a potential commodity ripe to not only impact, but possibly revolutionize, tech-driven markets and economies around the world.
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).[244][245] Some believe it generates an estimated $36 billion market.[246] 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.[237] 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.[247]

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.

Molecular analytical techniques developed in the late 20th century are being applied to questions of taxonomic classification. This has resulted in many reclassifications based on evolutionary systematics. Several studies of Random Amplified Polymorphic DNA (RAPD) and other types of genetic markers have been conducted on drug and fiber strains of Cannabis, primarily for plant breeding and forensic purposes.[73][74][24][75][76] Dutch Cannabis researcher E.P.M. de Meijer and coworkers described some of their RAPD studies as showing an "extremely high" degree of genetic polymorphism between and within populations, suggesting a high degree of potential variation for selection, even in heavily selected hemp cultivars.[36] They also commented that these analyses confirm the continuity of the Cannabis gene pool throughout the studied accessions, and provide further confirmation that the genus consists of a single species, although theirs was not a systematic study per se.
Cannabis sativa is extremely unusual in the diversity of products for which it is or can be cultivated. Popular Mechanics magazine (1938) touted hemp as “the new billion dollar crop,” stating that it “can be used to produce more than 25,000 products, ranging from dynamite to Cellophane.” Table 1 presents the principal products for which the species is cultivated in Europe, all of which happen to be based on fiber. This presentation stresses the products that hold the most promise for North America, which also include a considerable range of oilseed applications (Table 2; Fig. 1).

The most pressing need of the hemp industry in North America is for the breeding of more productive oilseed cultivars. At present, mainly European cultivars are available, of which very few are suitable for specialized oilseed production. More importantly, hempseed oil is not competitive, except in the novelty niche market, with the popular food oils. As argued above, to be competitive, hemp should produce approximately 2 t/ha; at present 1 t/ha is considered average to good production. Doubling the productive capacity of a conventional crop would normally be considered impossible, but it needs to be understood just how little hemp has been developed as an oilseed. There may not even be extant land races of the kind of hemp oilseed strains that were once grown in Russia, so that except for a very few very recent oilseed cultivars, there has been virtually no breeding of oilseed hemp. Contrarily, hemp has been selected for fiber to the point that some breeders consider its productivity in this respect has already been maximized. Fiber strains have been selected for low seed production, so that most hemp germplasm has certainly not been selected for oilseed characteristics. By contrast, drug varieties have been selected for very high yield of flowers, and accordingly produce very high yield of seeds. Drug varieties have been observed to produce more than a kilogram of seed per plant, so that a target yield of several tonnes per hectare is conceivable (Watson and Clarke 1997). Of course, the high THC in drug cultivars makes these a difficult source of germplasm. However, wild plants of C. sativa have naturally undergone selection for high seed productivity, and are a particularly important potential source of breeding germplasm.

During my visit, Penny showed me how she administers Harper’s CBD oils. We stood in her kitchen, where a window opened onto a vista of green grass and a wooden swing set out back. After carefully mixing and measuring Harper’s oils, Penny poured the liquid into a jumbo-sized plastic syringe. “We put this all online,” she told me, referring to the several YouTube videos she has made to help other parents administer hemp oil. Penny leaned down over her daughter to fit the tip of the syringe into her gastronomy tube, and I stood by silently. Harper looked at Penny, and Penny smiled back at her, and eased the plunger down.


The downsides of graphene are its dwindling sources and costly process to mine and import from rural areas in China and India. Hemp, however, can be grown in almost any terrain or country, and produces hemp bast, the key material used to replace graphene, as a waste byproduct of hemp processing. According to Mitlin’s research, hemp processing is 1,000 times cheaper than graphene processing.
CDFA has not yet proposed any regulations regarding industrial hemp. Regulations pertaining to cultivation will be developed in conjunction with the Industrial Hemp Advisory Board, and will be promulgated through the regular rulemaking process in accordance with the California Administrative Procedures Act. CDFA will notify the public via our electronic mailing list as regulations are posted and available for public comment.

Traditionally, hemp stalks would be water-retted first before the fibers were beaten off the inner hurd by hand, a process known as scutching. As mechanical technology evolved, separating the fiber from the core was accomplished by crushing rollers and brush rollers that would produce a nearly clean fiber. After the Marijuana Tax Act was implemented in 1938, the technology for separating the fibers from the core remained "frozen in time".

The first step to finding your correct CBD dosage is getting as much information as you can about the product you’re using. What is the concentration of CBD? Are there third-party lab tests that can confirm that? The CBD industry is still mainly a grassroots therapeutic movement, and as such, largely unregulated. Concentration and purity levels can differ greatly depending on the manufacturing process.  


But there’s a big difference between the two. Hemp seed oil has been pressed from hemp seed, and it’s great for a lot of things – it’s good for you, tastes great, and can be used in soap, paint – even as biodiesel fuel. However, hemp seed oil does not contain any concentration of cannabinoids at all, including CBD. So by all means, stock up at your local natural food store. Just don’t expect to reap the benefits of a true CBD oil when you cook with hemp seed oil.

Harvesting tall varieties for grain is difficult. In France, the principal grower of dual-purpose varieties, the grain is taken off the field first, leaving most of the stalks for later harvest (Fig. 49). Putting tall whole plants through a conventional combine results in the straw winding around moving parts, and the fibers working into bearings, causing breakdown, fires, high maintenance, and frustration. Following the French example of raising the cutting blade to harvest the grain is advisable. Growing short varieties dedicated to grain production eliminates many of the above problems, and since the profitability of hemp straw is limited at present, seems preferable. Grain growers should be aware that flocks of voracious birds are a considerable source of damage to hempseed, particularly in small plantations.


CBD Isolates/Concentrates: Anyone familiar with smoking hash or other cannabis concentrates like wax and BHO will be no stranger to this delivery method. Simply sprinkle some into a vaporizer or water pipe, ignite, inhale, and enjoy! We find that this option is useful for individuals looking to elevate their regular consumption of CBD-rich cannabis flowers or other smokable herbs.
Every crop grown and every variety may be inspected and sampled by a TDA plant inspector prior to harvest. The grower should contact TDA 30 days prior to harvest for inspection. The license holder is responsible for paying all fees associated with the sample. Each sample is $150. Please keep in mind that the way you set up your production method, may influence the number of samples required to represent the amount of material being produced. Growing multiple varieties will also increase the sampling cost.
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.

Despite advanced analytical techniques, much of the cannabis used recreationally is inaccurately classified. One laboratory at the University of British Columbia found that Jamaican Lamb’s Bread, claimed to be 100% sativa, was in fact almost 100% indica (the opposite strain).[82] Legalization of cannabis in Canada (as of October 17, 2018) may help spur private-sector research, especially in terms of diversification of strains. It should also improve classification accuracy for cannabis used recreationally. Legalization coupled with Canadian government (Health Canada) oversight of production and labelling will likely result in more -- and more accurate -- testing to determine exact strains and content. Furthermore, the rise of craft cannabis growers in Canada should ensure quality, experimentation/research, and diversification of strains among private-sector producers.[83]
In short, Cannabidiol – or CBD – is a cannabis compound that has many therapeutic benefits. Usually extracted from the leaves and flowers of hemp plants – though marijuana can also be a source – CBD oil is then incorporated into an array of marketable products. These products vary from the most common, like sublingual oils and topical lotions, to the less common (think CBD lattes). Basically, if you can dream it, you can buy it.
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.
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.[47] 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.[52][61] 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.[47][63]

Under federal law, cannabis (from which both CBD and marijuana are derived) is illegal everywhere, although the laws against it aren’t generally enforced in states that have legalized marijuana. Some manufacturers claim that CBD culled from legally imported industrial hemp, which has little to no THC, is fine to ship across the U.S., but many experts disagree, noting that because hemp comes from the same species as marijuana, cannabis sativa, all CBD falls under the DEA’s Schedule 1 designation. “This creative interpretation of the law runs afoul of reality,” says the Brookings Institution, a Washington, DC, think tank.
The question of whether heteromorphic sex chromosomes are indeed present is most conveniently answered if such chromosomes were clearly visible in a karyotype. Cannabis was one of the first plant species to be karyotyped; however, this was in a period when karyotype preparation was primitive by modern standards (see History of Cytogenetics). Heteromorphic sex chromosomes were reported to occur in staminate individuals of dioecious "Kentucky" hemp, but were not found in pistillate individuals of the same variety. Dioecious "Kentucky" hemp was assumed to use an XY mechanism. Heterosomes were not observed in analyzed individuals of monoecious "Kentucky" hemp, nor in an unidentified German cultivar. These varieties were assumed to have sex chromosome composition XX.[31] According to other researchers, no modern karyotype of Cannabis had been published as of 1996.[32] Proponents of the XY system state that Y chromosome is slightly larger than the X, but difficult to differentiate cytologically.[33]
If you live in a state where CBD is legal for your condition, it’s best to buy it from a state-regulated dispensary. But even there, oversight is uneven. “I feel safe being a cannabis consumer in Colorado, since the state tracks everything from seed to sale, but I didn’t the first few years after cannabis became legal,” when the rules were still taking shape, says Robyn Griggs Lawrence, the Boulder author of The Cannabis Kitchen Cookbook, which features recipes for cannabis edibles.
An absence of such fiber-strain traits as tallness, limited branching, long internodes, and very hollow stems, is characteristic of narcotic strains. Drug forms have historically been grown in areas south of the north-temperate zone, often close to the equator, and are photoperiodically adapted to a long season. When grown in north-temperate climates maturation is much-delayed until late fall, or the plants succumb to cold weather before they are able to produce seeds. Unlike fiber strains that have been selected to grow well at extremely high densities, drug strains tend to be less persistent when grown in high concentration (de Meijer 1994). Drug strains can be very similar in appearance to fiber strains. However, a characteristic type of narcotic plant was selected in southern Asia, particularly in India and neighboring countries. This is dioecious, short (about a meter in height), highly branched, with large leaves (i.e. wide leaflets), and it is slow to mature. The appearance is rather like a short, conical Christmas tree.
Cannabis, (genus Cannabis), plant belonging to the family Cannabaceae of the nettle order (Urticales). By some classifications, the genus Cannabis comprises a single species, hemp (Cannabis sativa), a stout, aromatic, erect annual herb that originated in Central Asia and is now cultivated worldwide, including in Europe, southern Asia, the Middle East, India, Africa, and the Americas. A tall canelike variety is raised for the production of hemp fibre, while the female plant of a short branchier variety is prized as the more abundant source of the psychoactive substance tetrahydrocannabinol (THC), the active ingredient of marijuana.

These CBD-only laws also attempt to impose some regulation on CBD oils, such as establishing how much CBD and THC such products must contain. For example, on June 1, the day I sat down with Hernandez in Fort Worth, Texas, Governor Greg Abbott signed the state’s Compassionate Use Act into law in Austin. The law requires that all CBD products contain no more than 0.5 percent THC and at least 10 percent CBD. However, the bill does not specify how the state plans to enforce this requirement. The law contains no language outlining how laboratories can test CBD products, what kinds of standards they would use, or who would regulate them.
The more recently House-approved version, which introduced the well-publicized provision affecting up to two million Supplemental Nutrition Assistance Program (SNAP) recipients, doesn't take such steps to remove federal barriers around hemp. It also stipulates that anyone with a felony drug conviction would be barred indefinitely from participating in federal or state hemp programs.

CBD’s potential usefulness in treating certain conditions is yet another argument in favor of legalizing the entire cannabis plant. Removing cannabis from the federal list of Schedule I narcotics that are illegal under the Controlled Substances Act would allow scientists to research its full medical potential and pharmaceutical companies in the United States to develop marijuana-based drugs and submit them for FDA approval. Government-regulated labs could test products like CBD oil to ensure safety and quality. Doctors could prescribe marijuana- based medicines with full knowledge of potential side effects and drug interactions, and without fear of losing their medical licenses or being thrown in jail.
The pulp and paper industry based on wood has considered the use of hemp for pulp, but only on an experimental basis. Hemp’s long fibers could make paper more recyclable. Since virgin pulp is required for added strength in the recycling of paper, hemp pulp would allow for at least twice as many cycles as wood pulp. However, various analyses have concluded that the use of hemp for conventional paper pulp is not profitable (Fertig 1996).
Mike, what kind of breast cancer (invasive ductal, I presume)? How many of her lymph nodes were positive? How big was the primary tumor? Reason I ask is that in women with Stage I or IIA tumors that are estrogen-and progesterone-receptor-positive and HER2-negative (ER+/PR+/HER2-) with three or fewer positive lymph nodes, there is a genomic assay test on a sample of the tumor, called OncotypeDX, that will tell doctors whether chemo is necessary or would even work at all. Medicare covers that test 100%.That type of breast cancer mentioned above, which I had as Stage IA, is treated in postmenopausal women with anti-estrogen drugs called aromatase inhibitors(aka AIs: anastrazole, letrozole, or exemestane)which have as a side effect joint pain. CBD oil is effective for this joint pain it is not, I repeat, NOT a substitute for chemo, radiation or these anti-estrogen drugs.So don’t assume your mom’s cancer will require chemo; but if it does, CBD helps with those side effects as well. If she lives in a state where medical marijuana is legal, there are doctors who sub-specialize in certifying applications for a medical marijuana card, and in the interim before the card is issued can advise as to the appropriate dose of CBD oil (legal and over-the-counter in all 50 states). Some (though not most) medical oncologists will certify their own patients’ medical marijuana card applications so she need not seek out another doctor; and will advise the appropriate dose for her symptoms. Once she gets her card, the “budtenders” in the licensed dispensaries can advise her as to the right CBD product (with or without THC), strength, and dosage. If she lives in a state where recreational weed is legal, the “budtenders” in the marijuana shops can steer her to the right strength of CBD oil and the right dosage.
