I use a cbd oil that is 1/1 thc. I had desperately hoped for pain control but while it helped a little while on low dose fentanyl, without I get no relief to speak of. The positive is in its helping my severe digestive issues! I have not been able to eat or digest what I ate for many years and with the use of this oil I am actually gaining weight! I was losing as much as five pounds a week! Just wish it helped with pain control!
Preliminary work in Germany (noted in Karus and Leson 1994) suggested that hemp could be grown on soils contaminated with heavy metals, while the fiber remained virtually free of the metals. Kozlowski et al. (1995) observed that hemp grew very well on copper-contaminated soil in Poland (although seeds absorbed high levels of copper). Baraniecki (1997) found similar results. Mölleken et al. (1997) studied effects of high concentration of salts of copper, chromium, and zinc on hemp, and demonstrated that some hemp cultivars have potential application to growth in contaminated soils. It would seem unwise to grow hemp as an oilseed on contaminated soils, but such a habitat might be suitable for a fiber or biomass crop. The possibility of using hemp for bioremediation deserves additional study.

According to DSM-V criteria, 9% of those who are exposed to cannabis develop cannabis use disorder, compared to 20% for cocaine, 23% for alcohol and 68% for nicotine. Cannabis abuse disorder in the DSM-V involves a combination of DSM-IV criteria for cannabis abuse and dependence, plus the addition of craving, minus the criterion related to legal troubles.[117]

“THC can be present in products advertised as CBD products, which are not regulated by the FDA. The presence of THC in urine would trigger a positive result on a drug test. Testing will not determine if THC is from CBD or marijuana use," March wrote to WECT about the NHRMC note. “We have advised employees that using CBD products could put them at risk for a positive drug test result.”


"In the past there has been ongoing tension between federal and state authorities over state hemp policies. After North Dakota passed its own state law authorizing industrial hemp production in 1999,62 researchers repeatedly applied for, but did not receive, a DEA permit to cultivate hemp for research purposes in the state.63 Also in 2007, two North Dakota farmers were granted state hemp farming licenses and, in June 2007, filed a lawsuit in U.S. District Court (North Dakota) seeking 'a declaratory judgment' that the CSA 'does not prohibit their cultivation of industrial hemp pursuant to their state licenses.'64 The case was dismissed in November 2007.65 The case was appealed to the U.S. Court of Appeals (Eighth Circuit) but was again dismissed in December 2009.66 The farmers filed an appeal in May 2010.67
Hash oil is a resinous matrix of cannabinoids obtained from the Cannabis plant by solvent extraction,[185] formed into a hardened or viscous mass.[186] Hash oil can be the most potent of the main cannabis products because of its high level of psychoactive compound per its volume, which can vary depending on the plant's mix of essential oils and psychoactive compounds.[187] Butane and supercritical carbon dioxide hash oil have become popular in recent years.[188]

If you have fibromyalgia, then you’ve probably heard of the rave reviews people post online about CBD’s effect on it. For those of you who don’t know, fibromyalgia is a type of chronic disorder that causes widespread muscle pain, pain in the bones, and general fatigue. Since the measure of pain is subjective, it cannot be recorded or measured by tests.
CBD is a cannabis-derived, nonpsychoactive (meaning it won’t get you high) hemp product that’s purportedly good for anxiety and relaxing muscles. The problem is that often you don’t know how much CBD you’re getting in whatever given product. Lord Jones, though, has been touted by everyone from Michelle Williams and Olivia Wilde to Katy Perry for foot relief during big awards shows (where brand-new heels reign). I got a sample from LJ and tried it — skeptically — after Bell told Strategist that she’s been hooked and trying to get everyone she knows onboard.
In 2015, The Hebrew University of Israel published a study that documented the potency of single-molecule CBD extract versus the potency of whole-plant CBD-rich extract. It found that extract taken from whole plant CBD-rich cannabis is therapeutically superior to single-molecule extract. The scientists behind this study noticed that science had been utilizing pure, single-molecule CBD, which resulted in a bell-shaped dose-response curve. This means that CBD’s efficacy plummets at very high and very low doses.
Thirty minutes later, I was surprised by how subtle the effect was. While I expected a hazy nodding-off effect similar to melatonin's, the oil simply relaxed my body ever so slightly—my heart stopped pounding against my chest, my legs stopped kicking beneath my sheets, my mind stopped racing. I wasn't sure if it was the oil or the late hour, but eventually, physical relaxation gave way to mental relaxation, and I drifted off to sleep.

Despite its centrality in human cultures across the globe, the European taxonomists who bequeathed Cannabis sativa its name didn’t quite get it right. When Carolus Linneaus came to naming the marijuana plant’s genus, he thought there was only one species, instead of the three we now know exist. Hence the confusion surrounding the fact that there are three distinct species of the genus Cannabis sativa, one of which is the sativa species.

The first example of the use of hempcrete was in 1986 in France with the renovation of the Maison de la Turquie in Nogent-sur-Seine by the innovator Charles Rasetti.[30] In the UK hemp lime was first used in 2000 for the construction of two test dwellings in Haverhill.[31] Designed by Modece Architects,[32] who pioneered hemp's use in UK construction, the hemp houses were monitored in comparison with other standard dwellings by BRE. Completed in 2009, the Renewable House is one of the most technologically advanced made from hemp-based materials.[33] The first US home made of hemp-based materials was completed in August 2010 in Asheville, North Carolina.[34]
"Hemp fields, in fact, could be a deterrent to marijuana growers. A strong case can be made that the best way to reduce the THC level of marijuana grown outdoors would be to grow industrial hemp near it. An experiment in Russia found that hemp pollen could travel 12 kilometers. This would mean that a hemp field would create a zone with a 12-kilometer radius within which no marijuana grower would want to establish a crop.

Drug policy is always clearest at the fringes. Illegal opioids are at one end. They are dangerous. Manufacturers and distributors belong in prison, and users belong in drug-treatment programs. The cannabis industry would have us believe that its product, like coffee, belongs at the other end of the continuum. “Flow Kana partners with independent multi-generational farmers who cultivate under full sun, sustainably, and in small batches,” the promotional literature for one California cannabis brand reads. “Using only organic methods, these stewards of the land have spent their lives balancing a unique and harmonious relationship between the farm, the genetics and the terroir.” But cannabis is not coffee. It’s somewhere in the middle. The experience of most users is relatively benign and predictable; the experience of a few, at the margins, is not. Products or behaviors that have that kind of muddled risk profile are confusing, because it is very difficult for those in the benign middle to appreciate the experiences of those at the statistical tails. Low-frequency risks also take longer and are far harder to quantify, and the lesson of “Tell Your Children” and the National Academy report is that we aren’t yet in a position to do so. For the moment, cannabis probably belongs in the category of substances that society permits but simultaneously discourages. Cigarettes are heavily taxed, and smoking is prohibited in most workplaces and public spaces. Alcohol can’t be sold without a license and is kept out of the hands of children. Prescription drugs have rules about dosages, labels that describe their risks, and policies that govern their availability. The advice that seasoned potheads sometimes give new users—“start low and go slow”—is probably good advice for society as a whole, at least until we better understand what we are dealing with.
As with a fermented food like kombucha, slight natural variations are normal and to be expected in a product such as CBD oil because it is made from living plants. Changes in the weather, soil, and water can all impact the biology of the source material. While we verify Certificates of Analysis (and take many other criteria into consideration during our review process), even the most reputable five-star companies have no way to control for every variable in this organic process.
Leafly is the world’s largest cannabis information resource, empowering people in legal cannabis markets to learn about the right products for their lifestyle and wellness needs. Our team of cannabis professionals collectively share years of experience in all corners of the market, from growing and retail, to science and medicine, to data and technology.
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.

United States National Institute of Health, University of Mississippi marijuana plantation site, showing variation in plant size. A tall fiber-type of hemp plant is shown at left, and a short narcotic variety (identified as “Panama Gold”) at right.
Cost is another consideration. Most CBD oils are sold in concentrations of 300 to 750 mg, although this may range from less than 100 mg to more than 2,000. A good indicator of price-point is the cost per milligram. Low-cost CBD oils usually fall between five and 10 cents per mg; mid-range prices are 11 to 15 cents per mg; and higher-end oils cost 16 cents per mg or higher. Given these varying per-milligram costs, a bottle of CBD oil may be priced anywhere from $10 or less to $150 or more.
The National Academy panel is more judicious. Its conclusion is that we simply don’t know enough, because there haven’t been any “systematic” studies. But the panel’s uncertainty is scarcely more reassuring than Berenson’s alarmism. Seventy-two thousand Americans died in 2017 of drug overdoses. Should you embark on a pro-cannabis crusade without knowing whether it will add to or subtract from that number?

"Both hemp and marijuana also have separate definitions in statute. While marijuana is defined in U.S. drug laws, Congress established a statutory definition for industrial hemp as “the plant Cannabis sativa L. and any part of such plant, whether growing or not, with a delta-9 tetrahydrocannabinol concentration of not more than 0.3 percent on a dry weight basis” as part of the 2014 farm bill.4 Hemp is generally characterized by plants that are low in delta-9 tetrahydrocannabinol (delta-9 THC), the dominant psychotrophic ingredient in Cannabis sativa.5
About half of the world market for hemp oil is currently used for food and food supplements (de Guzman 2001). For edible purposes, hempseed oil is extracted by cold pressing. Quality is improved by using only the first pressing, and minimizing the number of green seeds present. The oil varies in color from off-yellow to dark green. The taste is pleasantly nutty, sometimes with a touch of bitterness. Hemp oil is high in unsaturated fatty acids (of the order of 75%), which can easily oxidize, so it is unsuitable for frying or baking. The high degree of unsaturation is responsible for the extreme sensitivity to oxidative rancidity. The oil has a relatively short shelf life. It should be extracted under nitrogen (to prevent oxidation), protected from light by being kept in dark bottles, and from heat by refrigeration. Addition of anti-oxidants prolongs the longevity of the oil. Steam sterilization of the seeds, often required by law, allows air to penetrate and so stimulates rancidity. Accordingly, sterilized or roasted hemp seeds, and products made from hemp seed that have been subjected to cooking, should be fresh. The value of hemp oil from the point of view of the primary components is discussed below. In addition, it has been suggested that other components, including trace amounts of terpenes and cannabinoids, could have health benefits (Leizer et al. 2000). According to an ancient legend (Abel 1980), Buddha, the founder of Buddhism, survived a 6-year interval of asceticism by eating nothing but one hemp seed daily. This apocryphal story holds a germ of truth—hemp seed is astonishingly nutritional.

Short-term use of the drug impairs thinking and coordination. In long-term studies, teens who smoke marijuana have lower IQs later on, as well as structural differences in their brains, though scientists debate whether this is an effect of the drug or a result of habitual pot smokers seeking out less intellectually stimulating pursuits. A 2016 study on almost 300 students by the University of Montreal published in the journal Development and Psychopathology found that teens who start smoking around age 14 do worse on some cognitive tests by age 20 than non-smokers. They also have a higher school dropout rate. If they wait until age 17 to start, though, the smokers do not seem to have the same impairments, according to the study. 

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.”
Cannabis sativa L. subsp. sativa var. sativa is the variety grown for industrial use, while C. sativa subsp. indica generally has poor fiber quality and female buds from this variety are primarily used for recreational and medicinal purposes. The major differences between the two types of plants are the appearance, and the amount of Δ9-tetrahydrocannabinol (THC) secreted in a resinous mixture by epidermal hairs called glandular trichomes, although they can also be distinguished genetically.[59][61] Oilseed and fiber varieties of Cannabis approved for industrial hemp production produce only minute amounts of this psychoactive drug, not enough for any physical or psychological effects. Typically, hemp contains below 0.3% THC, while cultivars of Cannabis grown for medicinal or recreational use can contain anywhere from 2% to over 20%.[62]
CBD is readily obtainable in most parts of the United States, though its exact legal status is in flux. All 50 states have laws legalizing CBD with varying degrees of restriction, and while the federal government still considers CBD in the same class as marijuana, it doesn’t habitually enforce against it. In December 2015, the FDA eased the regulatory requirements to allow researchers to conduct CBD trials. Currently, many people obtain CBD online without a medical cannabis license. The government’s position on CBD is confusing, and depends in part on whether the CBD comes from hemp or marijuana. The legality of CBD is expected to change, as there is currently bipartisan consensus in Congress to make the hemp crop legal which would, for all intents and purposes, make CBD difficult to prohibit.
Thank you. I am 81 and started the CBD drops night and morning. I sleep better and no longer suffer the excruciating pain from diverticulitis. I saw somewhere that for my asthma I need the THC so got some (totally illegal here in South Africa). I think it is helping. The diagnosis of COPD was made some years ago and as a health psychologist I do all I can to remain healthy for my 97th birthday!! (Both my grandmother and greatgrandmother did so I believe I will too).

The plant was first given its taxonomic identification by Carl Linnaeus in 1753 and thoroughly described to Westerners in the 1800s, when the medical doctor William O'Shaughnessy gave a report to the Medical and Physical Society of Calcutta in India in 1839. The doctor described its effects on people and did a few case reports on "gunjah," the Indian name for the drug.
Right now, due to arcane laws that are about to change around the world, and strange licensing procedures, cannabis is a supply issue, but that will all change over time.  Cannabis is a plant that can grow in 12 weeks, 16 weeks for some Indica strains.  There will never be a shortage or issue with getting cannabis when it is a plant that can be produced anywhere in the world, in large batches, every 12 weeks.
The following sketch of hemp cultivation is insufficient to address all of the practical problems that are encountered by hemp growers. Bócsa and Karus (1998) is the best overall presentation of hemp growing available in English. The reader is warned that this book, as well as almost all of the literature on hemp, is very much more concerned with fiber production than oilseed production. McPartland et al. (2000) is the best presentation available on diseases and pests, which fortunately under most circumstances do limited damage. The resource list presented below should be consulted by those wishing to learn about hemp production. Provincial agronomists in Canada now have experience with hemp, and can make local recommendations. Particularly good web documents are: for Ontario (OMAFRA Hemp Series, several documents): www.gov.on.ca/OMAFRA/english/crops/hort/hemp.html); for Manitoba (several documents): www.gov.mb.ca/agriculture/crops/hemp/bko01s00.html; for British Columbia: (BC Ministry of Agriculture and Foods Fact Sheet on Industrial Hemp, prepared by A. Oliver and H. Joynt): www.agf.gov.bc.ca/croplive/plant/horticult/specialty/specialty.htm
There is great variation in Cannabis sativa, because of disruptive domestication for fiber, oilseed, and narcotic resin, and there are features that tend to distinguish these three cultigens (cultivated phases) from each other. Moreover, density of cultivation is used to accentuate certain architectural features. Figure 5 illustrates the divergent appearances of the basic agronomic categories of Cannabis in typical field configurations.
Henry Ford recognized the utility of hemp in early times. In advance of today’s automobile manufacturers, he constructed a car with certain components made of resin stiffened with hemp fiber (Fig. 19). Rather ironically in view of today’s parallel situation, Henry Ford’s hemp innovations in the 1920s occurred at a time of crisis for American farms, later to intensify with the depression. The need to produce new industrial markets for farm products led to a broad movement for scientific research in agriculture that came to be labeled “Farm Chemurgy,” that today is embodied in chemical applications of crop constituents.
"The single largest supplier of U.S. imports of raw and processed hemp fiber is China. Other leading country suppliers include Romania, Hungary, India, and other European countries. The single largest source of U.S. imports of hemp seed and oilcake is Canada. The total value of Canada’s exports of hemp seed to the United States has grown significantly in recent years following resolution of a long-standing legal dispute over U.S. imports of hemp foods in late 2004 (see 'Dispute over Hemp Food Imports (1999-2004)'). European countries have also supplied hemp seed and oilcake to the United States."

As noted in the previous section, CBD oil prices vary significantly by brand. The best practice for most is to determine a per-milligram budget for CBD oil, as well as a maximum price for the entire bottle. For example, you might decide that 10 cents per milligram or less is a reasonable budget; and that $45 (for a 450-mg concentration, based on the budget) is a maximum bottle price. Also, if ordering online, be sure to include potential shipping costs.


“THC can be present in products advertised as CBD products, which are not regulated by the FDA. The presence of THC in urine would trigger a positive result on a drug test.

Apart from Endoca CBD oils, you will also find other similar products, such as isolate, tinctures or creams. Some products are designed for pets too. The range offered by Endoca is not impressive when compared to more prestigious manufacturers, but you can still find anything you might need. Using in house green equipment and procedures for the manufacturing process, Endoca can also afford to keep the prices a little lower.


“What we know is that THC and CBD combined has a greater therapeutic effect than either one given alone,” Lee continued. “The best medicines to use are the medicines that have both THC and CBD. What we suggest to people – and I will emphasize we are not doctors – is that people should use products that have as much THC as possible, with the CBD, that doesn’t make them feel dysphoric or stoned.”
Sativex® (GW Pharmaceuticals) is an oromucosal whole cannabis-based spray combining a CB1 partial agonist (THC) with a cannabinoid system modulator (CBD), minor cannabinoids and terpenoids plus ethanol and propylene glycol excipients and peppermint flavoring (McPartland and Russo 2001; Russo and Guy 2006). It was approved by Health Canada in June 2005 for prescription for central neuropathic pain in multiple sclerosis, and in August 2007, it was additionally approved for treatment of cancer pain unresponsive to optimized opioid therapy. Sativex is a highly standardized pharmaceutical product derived from two Cannabis sativa chemovars following Good Agricultural Practice (GAP) (de Meijer 2004), yielding Tetranabinex® (predominantly-THC extract) and Nabidiolex® (predominantly-CBD extract) in a 1:1 ratio. Each 100 μL pump-action oromucosal Sativex spray actuation provides 2.7 mg of THC and 2.5 mg of CBD. Pharmacokinetic data are available, and indicate plasma half lives of 85 minutes for THC, 130 minutes for 11-hydroxy-THC and 100 minutes for CBD (Guy and Robson 2003). Sativex effects commence in 15–40 minutes, an interval that permits symptomatic dose titration. A very favorable adverse event profile has been observed in over 2500 patient years of exposure in over 2000 experimental subjects. Patients most often ascertain an individual stable dosage within 7–10 days that provides therapeutic relief without unwanted psychotropic effects (often in the range of 8–10 sprays per day). In all RCTs, Sativex was adjunctively added to optimal drug regimens in subjects with intractable symptoms, those often termed “untreatable.” Sativex is also available by named patient prescription in the UK and the Catalonia region of Spain. An Investigational New Drug (IND) application to study Sativex in advanced clinical trials in the USA was approved by the FDA in January 2006 in patients with intractable cancer pain.

Hemp has at times in the past been grown simply for its ornamental value. The short, strongly-branched cultivar ‘Panorama’ (Fig. 43) bred by Iván Bósca, the dean of the world’s living hemp breeders, was commercialized in Hungary in the 1980s, and has been said to be the only ornamental hemp cultivar available. It has had limited success, of course, because there are very few circumstances that permit private gardeners can grow Cannabis as an ornamental today. By contrast, beautiful ornamental cultivars of opium poppy are widely cultivated in home gardens across North America, despite their absolute illegality and the potentially draconian penalties that could be imposed. Doubtless in the unlikely event that it became possible, many would grow hemp as an ornamental.
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.

Omega-3 and omega-6s have been shown to help treat conditions like atopic dermatitis (a.k.a. eczema), which can leave your skin dry and itchy. GLA in particular has been shown to improve dry skin and eczema. One 2005 study even found people who consumed hempseed oil for 20 weeks had a reduction in oil and reduced the symptoms and appearance of eczema after 20 weeks. But that research is preliminary, Tishler points out.


The Spaniards brought hemp to the Americas and cultivated it in Chile starting about 1545.[117] Similar attempts were made in Peru, Colombia, and Mexico, but only in Chile did the crop find success.[118] 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. [119] 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;[120] 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.[121] The Puritans are first known to have cultivated hemp in New England in 1645.[117]
Cannabidiol—more commonly abbreviated as CBD—isn’t psychoactive and, apparently to the man’s disappointment, won’t get you high. Instead, many people report that consuming it makes them feel less anxious, helps them sleep, or eases joint pain. Over the past two years, CBD in the form of oils and supplements has become widely distributed across the United States, even in places with no level of cannabis legalization. Now the trend’s new frontier is food. My first clue that it had hit some kind of critical mass was seeing a local restaurant put a sign out front announcing the debut of CBD empanadas. From design-oriented Instagram seltzer to your local pizza place, brands and restaurants want you to order some CBD and eat your feelings.
At least 38 states considered legislation related to industrial hemp in 2018. These bills ranged from clarifying existing laws to establishing new licensing requirements and programs. At least six states – Alaska, Arizona, Kansas, Missouri, New Jersey and Oklahoma – enacted legislation in 2018 establishing hemp research and industrial hemp pilot programs. Georgia created the House Study Committee on Industrial Hemp Production. States, already allowing for industrial hemp programs, continued to consider policies related to licensure, funding, seed certification, and other issues. For example, Tennessee amended its Commercial Feed Law to include hemp. 
Since then, many different types of sex determination systems have been discovered, particularly in plants.[15] 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.[31]
