Cannabis lowers the pressure in the eye that causes optic nerve damage leading to glaucoma. Research has shown conclusively that marijuana users experience lower internal eye pressure while the body metabolizes THC. However, the psychoactive side effects of using THC to treat glaucoma make cannabis a nonviable medication for most people with the disease.
"CBD increases the circulating levels of your natural endocannabinoids, which, in turn, interact with your cannabinoid receptors," Bonn-Miller says. "CBD has also been shown to interact with serotonin receptors, and that may be part of why it has some beneficial effects on anxiety. It also interacts with some pain receptors, which may be why we're starting to see effects on pain and inflammation."
"Industrial hemp" means a fiber or oilseed crop, or both, that is limited to types of the plant Cannabis sativa L. having no more than three-tenths of 1 percent tetrahydrocannabinol (THC) contained in the dried flowering tops, whether growing or not; the seeds of the plant; the resin extracted from any part of the plant; and every compound, manufacture, salt, derivative, mixture, or preparation of the plant, its seeds or resin produced therefrom.
Hemp has the ability to mitigate the toxin transfer from contaminated soil into food products. This process uses phytoremediation, an organic process where toxins are absorbed by plant roots and then stored in the cellulose for disposal. Hemp phytoremediation became more well-known after the Chernobyl disaster for its use in helping grow crops that are safe for consumption.
Textile expert Elizabeth Wayland Barber summarizes the historical evidence that Cannabis sativa, "grew and was known in the Neolithic period all across the northern latitudes, from Europe (Germany, Switzerland, Austria, Romania, Ukraine) to East Asia (Tibet and China)," but, "textile use of Cannabis sativa does not surface for certain in the West until relatively late, namely the Iron Age."[107] "I strongly suspect, however, that what catapulted hemp to sudden fame and fortune as a cultigen and caused it to spread rapidly westwards in the first millennium B.C. was the spread of the habit of pot-smoking from somewhere in south-central Asia, where the drug-bearing variety of the plant originally occurred. The linguistic evidence strongly supports this theory, both as to time and direction of spread and as to cause."[108]
A 100-gram portion of hulled hemp seeds supplies 586 calories. They contain 5% water, 5% carbohydrates, 49% total fat, and 31% protein. Hemp seeds are notable in providing 64% of the Daily Value (DV) of protein per 100-gram serving.[19] Hemp seeds are a rich source of dietary fiber (20% DV), B vitamins, and the dietary minerals manganese (362% DV), phosphorus (236% DV), magnesium (197% DV), zinc (104% DV), and iron (61% DV). About 73% of the energy in hempseed is in the form of fats and essential fatty acids,[19] mainly polyunsaturated fatty acids, linoleic, oleic, and alpha-linolenic acids.[20]
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.
Soil characteristics, latitude and climatic stresses have been found to have significant effects on THC concentrations, and there are seasonal and even diurnal variations (Small 1979; Pate 1998b). However, the range of THC concentrations developed by low-THC cultivars (those typically with £0.3% THC) under different circumstances on the whole is limited, for the most part generally not varying more than 0.2 percentage points when grown in a range of circumstances, and usually less (note information in Scheifle et al. 1999; Scheifle 2000, Scheifle and Dragla 2000). Practically, this has meant in Canadian experience that a few cultivars have been eliminated from further commercial cultivation because they sometimes exceed the 0.3% level (‘Fedora 19’ and ‘Futura,’ authorized in 2000, have now been removed because some test results in several years exceeded 0.3%; ‘Finola’ and ‘Uniko B’ are under probation because of elevated levels), but on the whole most of the permitted cultivars have maintained highly consistent development of quite low levels of THC.
Its sturdy fibers have also been put to growing use in high-quality plastics and auto paneling, durable building materials, and other common industrial commodities. And when it comes to environmental impact, hemp is not only a low-fuss crop capable of flourishing in US farmland; it can also clean up tainted water and soil, bully weeds away, and be converted into biodiesel.
State policymakers have taken action to address various policy issues — the definition of hemp, licensure of growers, regulation and certification of seeds, state-wide commissions and legal protection of growers. At least 41 states have passed legislation related to industrial hemp, such as defining hemp and removing barriers, and at least 39 states have allowed for hemp cultivation and production programs. Some states establishing these programs require a change in federal laws or a waiver from the DEA prior to implementation.
It has been contended that hemp is notably superior to most crops in terms of biomass production, but van der Werf (1994b) noted that the annual dry matter yield of hemp (rarely approaching 20 t/ha) is not exceptional compared to maize, beet, or potato. Nevertheless, hemp has been rated on a variety of criteria as one of the best crops available to produce energy in Europe (Biewinga and van der Bijl 1996). Hemp, especially the hurds, can be burned as is or processed into charcoal, methanol, methane, or gasoline through pyrolysis (destructive distillation). As with maize, hemp can also be used to create ethanol. However, hemp for such biomass purposes is a doubtful venture in North America. Conversion of hemp biomass into fuel or alcohol is impractical on this continent, where there are abundant supplies of wood, and energy can be produced relatively cheaply from a variety of sources. Mallik et al. (1990) studied the possibility of using hemp for “biogas” (i.e. methane) production, and concluded that it was unsuitable for this purpose. Pinfold Consulting (1998) concluded that while there may be some potential for hemp biomass fuel near areas where hemp is cultivated, “a fuel ethanol industry is not expected to develop based on hemp.”
There are ways to strain dangerous contaminants out of raw hemp paste. And most companies stand behind their quality and safety procedures. “We continuously test all our products ... to ensure our consumers get the levels of natural constituents they expect from the quality hemp stalk oil they purchase,” HempMedsPx states on its web site. “Additionally, all our products are tested for safety, to ensure there are no solvents, heavy metals, or other potentially harmful materials in our oil. Because we take these steps, we are always confident in our products, and you can be too.”
Environmental sex determination is known to occur in a variety of species.[38] Many researchers have suggested that sex in Cannabis is determined or strongly influenced by environmental factors.[26] Ainsworth reviews that treatment with auxin and ethylene have feminizing effects, and that treatment with cytokinins and gibberellins have masculinizing effects.[14] It has been reported that sex can be reversed in Cannabis using chemical treatment.[39] A PCR-based method for the detection of female-associated DNA polymorphisms by genotyping has been developed.[40]

The US Drug Enforcement Administration’s online criminal justice statistics for 2000 ( shows the following seizures and eradication of plants of C. sativa: 40,929 outdoor plots (2,597,796 plants), 139,580,728 ditchweed (ruderal plants), 2,361 indoor operations (217,105 plants), for a grand total of 2,814, 903 plants destroyed. Impressively, the species was grown in all 50 states (including outdoor seizures in every state except Wyoming)! It is of course impossible to know exactly how much marijuana is cultivated in the United States, and perhaps only 10% to 20% of the amount grown is seized. The profitability of the illegal crop is indicated by a comparison of the cost of a bushel of corn (roughly $2.50) and a bushel of manicured marijuana (about $70,000; it has been suggested that prices range from $500 a pound, for low-quality marijuana, to more than $5,000 a pound for “boutique” strains like “Northern Lights” and “Afghan Kush”). According to a National Organization for the Reform of Marijuana Laws (NORML) ( marijuana is at least the fourth most valuable crop in America, outranked only by corn, soybeans, and hay. It was estimated that 8.7 million marijuana plants were harvested in 1997, worth $15.1 billion to growers and $25.2 billion on the retail market (the wholesale value was used to compare marijuana to other cash crops). Marijuana was judged to be the largest revenue producing crop in Alabama, California, Colorado, Hawaii, Kentucky, Maine, Rhode Island, Tennessee, Virginia, and West Virginia, and one of the top five cash crops in 29 other states.
Cannabis use generally makes psychotic symptoms worse and lowers the person’s chances of recovery from a psychotic episode. People with a psychotic illness who use drugs experience more delusions, hallucinations and other symptoms. They have a higher rate of hospitalisation for psychosis, and treatment is generally less effective for them. People with a psychotic illness should not use cannabis.

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.[27] In the UK hemp lime was first used in 2000 for the construction of two test dwellings in Haverhill.[28] Designed by Modece Architects,[29] 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.[30] The first US home made of hemp-based materials was completed in August 2010 in Asheville, North Carolina.[31]

Preliminary research indicates that cannabidiol may reduce adverse effects of THC, particularly those causing intoxication and sedation, but only at high doses.[26] Safety studies of cannabidiol showed it is well-tolerated, but may cause tiredness, diarrhea, or changes in appetite as common adverse effects.[27] Epidiolex documentation lists sleepiness, insomnia and poor quality sleep, decreased appetite, diarrhea, and fatigue.[3]

Senate Majority Leader Mitch McConnell (R-KY) introduced new legislation in April that would declassify non-psychoactive cannabis varieties -- more commonly referred to as hemp -- from the Controlled Substances Act. The legislative proposal comes as part of McConnell's Hemp Farming Act of 2018, which would remove barriers placed on banking access and water rights in addition to legalizing the crop.

Canadian experience with growing hemp commercially for the last 4 years has convinced many growers that it is better to use a single-purpose cultivar, seed or fiber, than a dual-purpose cultivar. The recent focus of Canadian hemp breeders has been to develop cultivars with high seed yields, low stature (to avoid channeling the plants’ energy into stalk, as is the case in fiber cultivars), early maturation (for the short growing seasons of Canada), and desirable fatty acid spectrum (especially gamma-linolenic acid).

Topicals represent a newer emerging market in medical marijuana products geared toward health and beauty. Cannabinoids can be absorbed through the skin for certain therapeutic benefits without any psychoactivity. Additionally, the essential oils in hemp and cannabis provide many benefits for skin health. From moisturizers to shampoos and deodorants, medical cannabis products continue to diversify.
In 2014, I founded New Frontier Data, an analytics and business intelligence reporting group dedicated to the global cannabis industry, after more than 20 years in finance, industry analytics, intelligence reporting and emerging markets. As such, I have had the privilege of following hemp’s emergence and evolution. Half a decade later, this robust, environmentally friendly, low -cost-to-produce plant has become one of the most diversely applied and globally significant natural resources in the world. Here is a look at its applications across several mature industries:

Hemp is the fiber and seed part of the Cannabis Sativa L. plant, opposed to the flower part of the plant which is “legally considered” marijuana.  The fiber and seeds are incredible valuable and is why hemp is often called a “cash crop”.  Hemp is a very hearty plant and grows very quickly in very diverse soil conditions.  Cultivation of hemp for industrial purposes has been done by many civilizations for over 12,000 years.   Industrial hemp was the desired fiber used to manufacture rope, canvas, paper, and clothing until alternative textiles and synthetics for these purposes were discovered.  Although China has been the largest hemp producer over the years, other countries such as Australia and Canada are catching up.  It has been illegal for anyone to grow hemp in the United States as hemp is illegal under the marijuana prohibition act but Colorado has changed the laws and paved the way for industrial hemp production again in the United States(see hemp history). Now hemp oils, hemp plastics, hemp building materials and many hemp fiber products can be seen and purchased on the market. Hemp is truly an amazing plant with the potential to help “green up” many industries.
Side effects of CBD include sleepiness, decreased appetite, diarrhea, fatigue, malaise, weakness, sleeping problems, and others.[3] It does not have intoxicating effects like those caused by THC, and may have an opposing effect on disordered thinking and anxiety produced by THC.[7][10][11] CBD has been found to interact with a variety of different biological targets, including cannabinoid receptors and other neurotransmitter receptors.[7][12] The mechanism of action of CBD in terms of its psychoactive and therapeutic effects is not fully clear.[7]
Cannabis can be prepared into various foods generally called ‘edibles’. It takes between 1-3 hours to feel the effects after eating cannabis.2 Impatient or naïve users may believe they have not taken enough to feel the effects, and if they consume more they may find later that the psychoactive effects are unpleasantly strong. When edible products have inconsistent levels of THC even experienced users may find it difficult to regulate the amount consumed.
Cannabinoids, terpenoids, and other compounds are secreted by glandular trichomes that occur most abundantly on the floral calyxes and bracts of female plants.[41] As a drug it usually comes in the form of dried flower buds (marijuana), resin (hashish), or various extracts collectively known as hashish oil.[7] In the early 20th century, it became illegal in most of the world to cultivate or possess Cannabis for sale or personal use.

Alternatively, call Alcohol and Drug Helpline 0800 787 797 for confidential, non-judgmental advice and referral to a local service provider.

As the demand for CBD products has increased, some states have started to take action. Over the past two years, 17 states have passed “CBD-only” laws, assuring parents who purchase CBD oil to treat their sick children that they won’t face arrest or prosecution from state law enforcement for possessing what the federal government still considers a Schedule I narcotic.
CBD is a 5-HT1A receptor agonist, which may also contribute to an anxiolytic effect.[146] This likely means the high concentrations of CBD found in Cannabis indica mitigate the anxiogenic effect of THC significantly.[146] The cannabis industry claims that sativa strains provide a more stimulating psychoactive high while indica strains are more sedating with a body high.[147] However this is disputed by researchers.[148]

The Gateway Hypothesis states that cannabis use increases the probability of trying "harder" drugs. The hypothesis has been hotly debated as it is regarded by some as the primary rationale for the United States prohibition on cannabis use.[249][250] A Pew Research Center poll found that political opposition to marijuana use was significantly associated with concerns about health effects and whether legalization would increase marijuana use by children.[251]
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.
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.
Medical reviews published in 2017 and 2018 incorporating numerous clinical trials concluded that cannabidiol is an effective treatment for certain types of childhood epilepsy.[19][20] An orally administered cannabidiol solution (brand name Epidiolex) was approved by the US Food and Drug Administration in June 2018 as a treatment for two rare forms of childhood epilepsy, Lennox-Gastaut syndrome and Dravet syndrome.[13]
According to Delphic analysis by British researchers in 2007, cannabis has a lower risk factor for dependence compared to both nicotine and alcohol.[97] However, everyday use of cannabis may be correlated with psychological withdrawal symptoms, such as irritability or insomnia,[93] and susceptibility to a panic attack may increase as levels of THC metabolites rise.[98][99] However, cannabis withdrawal symptoms are typically mild and are never life-threatening.[100]
Hemp’s greatest obstacle is its association with psychoactive cannabis, despite the important distinction that hemp contains only nominal amounts (no more than 0.3%) of the psychoactive ingredient, tetrahydrocannabinol (THC). Although the U.S. is the largest importer of hemp products according to the Hemp Business Journal (a New Frontier Data subsidiary), hemp itself has struggled to gain social acceptance in the country and elsewhere. For instance, current U.S. legislation only permits universities and states performing agricultural or academic research to cultivate hemp. However, the 2018 Farm Bill currently in Congress would grant hemp full legalization across the nation. Passage of this bill would be a key step in promoting public acceptance in the U.S. and elsewhere, allowing the country to participate in the rapidly growing global hemp market.

Medical marijuana can soothe nausea and increase appetite, quiet pain, soothe anxiety and even reduce epileptic seizures. Other research on the healing effects of cannabis is being examined. For example, research suggests that THC may be able to improve memory according to a 2016 study on mice. More than half of the United States has legalized marijuana for medical use.

Selection for fiber has resulted in strains that have much more bark fiber tissues and much less woody core than encountered in narcotic strains, oilseed strains, and wild plants (Fig. 12). In non-fiber strains of Cannabis, bark can be less than one quarter of the stem tissues (i.e. more than three quarters can be woody core). By contrast, in fiber strains half of the stem tissues can be bark, and more than half of this can be the desirable long primary fibers (de Meijer 1995). Non-fiber strains rarely have as much as 15% fiber in the bark.

A USDA analysis of hemp, “Industrial hemp in the United States: Status and market potential,” was issued in 2000, and is available at This is anonymously-authored, therefore presumably represents a corporate or “official” evaluation. The conclusion was that “US markets for hemp fiber (specialty textiles, paper, and composites) and seed (in food or crushed for oil) are, and will likely remain, small, thin markets. Uncertainty about longrun demand for hemp products and the potential for oversupply discounts the prospects for hemp as an economically viable alternative crop for American farmers.” Noting the oversupply of hempseeds associated with Canada’s 12,000 ha in 1999, the report concluded that the long term demand for hemp products is uncertain, and predicts that the hemp market in the US will likely remain small and limited. With respect to textiles, the report noted the lack of a thriving textile flax (linen) US industry (despite lack of legal barriers), so that it would seem unlikely that hemp could achieve a better market status. With respect to hemp oil, the report noted that hemp oil in food markets is limited by its short shelf life, the fact that it can not be used for frying, and the lack of US Food and Drug Administration approval as GRAS (“generally recognized as safe”). Moreover, summarizing four state analyses of hemp production (McNulty 1995, Ehrensing 1998, Kraenzel et al. 1998, Thompson et al. 1998), profitability seemed doubtful.
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.
In the United States, over three million people suffer from epilepsy – 470,000 of those people are children. Epilepsy is a disorder of the brain that causes seizures – of which there are over thirty different kinds, ranging from mild and infrequent to life-threatening. Not surprisingly, people with epilepsy face significant challenges – from the cost of healthcare to work limitations and social isolation.

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]
The manufacturer will probably give you a recommended dosage, but bear in mind that this isn’t set in stone. What you need to find is your own minimum effective dose. “Minimum effective dose” is a medical term which refers to the amount of a substance you need for the results you want, and above which, the substance doesn’t increase in effectiveness.

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.

This may be a good place to point out that not all CBD products are created equal. The industry is still largely unregulated, and the quality and quantity of CBD in a given product will vary wildly. Third party testing definitely helps to monitor companies’ claims, but it’s still up to you as the consumer to do your homework on the best CBD products.

The use of Cannabis as a mind-altering drug has been documented by archaeological finds in prehistoric societies in Eurasia and Africa.[84] The oldest written record of cannabis usage is the Greek historian Herodotus's reference to the central Eurasian Scythians taking cannabis steam baths.[85] His (c. 440 BCE) Histories records, "The Scythians, as I said, take some of this hemp-seed [presumably, flowers], and, creeping under the felt coverings, throw it upon the red-hot stones; immediately it smokes, and gives out such a vapour as no Grecian vapour-bath can exceed; the Scyths, delighted, shout for joy."[86] Classical Greeks and Romans were using cannabis, while in the Middle East, use spread throughout the Islamic empire to North Africa. In 1545, cannabis spread to the western hemisphere where Spaniards imported it to Chile for its use as fiber. In North America, cannabis, in the form of hemp, was grown for use in rope, clothing and paper.[87][88][89][90]

Medical cannabis, or medical marijuana, can refer to the use of cannabis and its cannabinoids to treat disease or improve symptoms; however, there is no single agreed-upon definition.[38][39] The rigorous scientific study of cannabis as a medicine has been hampered by production restrictions and other federal regulations.[40] There is limited evidence suggesting cannabis can be used to reduce nausea and vomiting during chemotherapy, to improve appetite in people with HIV/AIDS, and to treat chronic pain and muscle spasms.[41][42][43] Its use for other medical applications is insufficient for conclusions about safety or efficacy.
The Spaniards brought hemp to the Americas and cultivated it in Chile starting about 1545.[110] Similar attempts were made in Peru, Colombia, and Mexico, but only in Chile did the crop find success.[111] In July 1605, Samuel Champlain reported the use of grass and hemp clothing by the (Wampanoag) people of Cape Cod and the (Nauset) people of Plymouth Bay told him they harvested hemp in their region where it grew wild to a height of 4 to 5 ft. [112] In May 1607, "hempe" was among the crops Gabriel Archer observed being cultivated by the natives at the main Powhatan village, where Richmond, Virginia is now situated;[113] and in 1613, Samuell Argall reported wild hemp "better than that in England" growing along the shores of the upper Potomac. As early as 1619, the first Virginia House of Burgesses passed an Act requiring all planters in Virginia to sow "both English and Indian" hemp on their plantations.[114] The Puritans are first known to have cultivated hemp in New England in 1645.[110]
