Some jurisdictions use free voluntary treatment programs and/or mandatory treatment programs for frequent known users. Simple possession can carry long prison terms in some countries, particularly in East Asia, where the sale of cannabis may lead to a sentence of life in prison or even execution. Political parties, non-profit organizations, and causes based on the legalization of medical cannabis and/or legalizing the plant entirely (with some restrictions) have emerged in such countries as China and Thailand.[213][214]
Many animal studies have previously demonstrated that delta-9-THC and other cannabinoids have a stimulatory effect on appetite and increase food intake. It is believed that the endogenous cannabinoid system may serve as a regulator of feeding behavior. The endogenous cannabinoid anandamide potently enhances appetite in mice.[39] Moreover, CB1 receptors in the hypothalamus may be involved in the motivational or reward aspects of eating.[40]
The 2014 US Farm Bill allows states that have passed their own industrial hemp legislation to grow industrial hemp for purposes of research and development. Several states — including Kentucky, Colorado, and Oregon — are already conducting hemp pilot projects. Many other states are currently pursuing similar legislation and programs. After many years of prohibition, American farmers are finally reacquainting themselves with industrial hemp.
"Cannabinoids have been found to have antioxidant properties, unrelated to NMDA receptor antagonism. This new found property makes cannabinoids useful in the treatment and prophylaxis of wide variety of oxidation associated diseases, such as ischemic, age-related, inflammatory and autoimmune diseases. The cannabinoids are found to have particular application as neuroprotectants, for example in limiting neurological damage following ischemic insults, such as stroke and trauma, or in the treatment of neurodegenerative diseases, such as Alzheimer's disease, Parkinson's disease and HIV dementia.
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.

Everything you need to know about marijuana (cannabis) Marijuana, or cannabis, is the most commonly used illicit drug in the world. It alters the mood and affects nearly every organ in the body. With at least 120 active compounds, marijuana may have health benefits as well as risks. We describe these, addiction, and withdrawal. Learn more about cannabis here. Read now
Hello Roy,We will attempt to help you as much as possible.As you know CBD is a new treatment option so there are almost no scientific studies and very few case studies available. However as a general rule the best thing to do is just to start.We say this because everyones body metabolizes CBD at different rates. So the best way to find the proper dosage for you is just to start. The good news is that feeling sleepy is about the only side effect of overdosing CBD, so experimentation is pretty safe.What we recommend on our site is to start with 25mg of CBD taken as often as you need it throughout the day. If you find this works stick with it. If you find you need more, or are having to take it too many times during the day, then take more such as 50mg with each serving.Which oil should you use that will ship to the UK? We have reviewed all the top CBD oil products and have found Endoca to be the best and most powerful oil on the market. If you are going to use CBD hemp oil we recommend using raw CBD oil. This is the most natural and has the highest amount of plant constituents present which increases effectiveness.The best oil to start with is Endoca Raw Hemp Oil 2000mg. If taking 50mg a day this tube will last you 40 days. If you are taking 200mg a day you will need to purchase 3 tubes per month.Read the full review here: https://cbdoilreview.org/endoca-raw-hemp-oil-2000mg/Buy the product here: https://cbdoilreview.org/product/endoca-raw-hemp-oil-2000mg/Endoca ships to the UK from their European headquarters so you are good to go there.

There are practical, if cruder alternatives to separate the long fiber for high-quality textile production, but in fact such techniques are used mostly for non-textile applications. This involves production of “whole fibers” (i.e. harvesting both the long fibers from the cortex and the shorter fibers from throughout the stem), and technologies that utilize shortened hemp fibers. This approach is currently dominant in western Europe and Canada, and commences with field dew retting (typically 2–3 weeks). A principal limitation is climatic—the local environment should be suitably but not excessively moist at the close of the harvest season. Once stalks are retted, dried, and baled, they are processed to extract the fiber. In traditional hemp processing, the long fiber was separated from the internal woody hurds in two steps, breaking (stalks were crushed under rollers that broke the woody core into short pieces, some of which were separated) and scutching (the remaining hurds, short fibers (“tow”) and long fibers (“line fiber, ” “long-line fiber”) were separated). A single, relatively expensive machine called a decorticator can do these two steps as one. In general in the EU and Canada, fibers are not separated into tow and line fibers, but are left as “whole fiber.” In western Europe, the fiber is often “cottonized,” i.e. chopped into short segments the size of cotton and flax fiber, so that the fibers can be processed on flax processing machinery, which is very much better developed than such machinery is for hemp. In North America the use of hemp for production of even crude textiles is marginal. Accordingly, the chief current fiber usages of North American, indeed of European hemp, are non-textile.
The public forum sessions provided an overview of the Alternative Crop Research Act, including the legal parameters set within the bill, and the procedures that will guide development of the rules and regulations. Guest speakers included Brent Burchett, the director of the plant division from the Kentucky Department of Agriculture, and Mitch Yergert, retired director of the division of plant industry from the Colorado State Department of Agriculture.

Dosage is important, because CBD can have side effects—the most common are tiredness, diarrhea, and changes in appetite and weight—so it’s best not to take more than you need. As CBD becomes more prevalent, says J. Michael Bostwick, M.D., a psychiatrist at Mayo Clinic in Rochester, MN, “I’m reasonably certain new kinds of side effects will emerge.”
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.
Another field in which CBD is creating a buzz is in the area of mood disorders like anxiety and depression. Both conditions have been treated with a variety of medications, courtesy of Big Pharma, that have had varying levels of success. Again, the long list of side effects can be off-putting to someone who just wants to get through the day without the sweaty tension of anxiety or the gray haze of depression.
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]

Hi, Congrats on finishing chemo & radiation that’s awesome!! I wish you the best of luck!! I was actually wanting to know about dosage for cancer as well..My parents both have recently been diagnosed with cancer 4 months apart and are currently going thru chemo together. I have tried looking for the dosage info but can never find what i’m looking for..I want to try to help lesson the chemo side effects and hopefully kill some of the cancer cells. Can someone please help us?Thank You Christy
Cannabis is first referred to in Hindu Vedas between 2000 and 1400 BCE, in the Atharvaveda. By the 10th century CE, it has been suggested that it was referred to by some in India as "food of the gods".[115] Cannabis use eventually became a ritual part of the Hindu festival of Holi. One of the earliest to use this plant in medical purposes was Korakkar, one of the 18 Siddhas.[116][117] The plant is called Korakkar Mooli in the Tamil language, meaning Korakkar's herb.[118][119]

Rather than keeping people out of the industry, Money thinks regulators should focus on helping farmers sell their products: for example, by connecting them with the "biomass brokers" who deal in the fibers, stalks, and seed matter produced by industrial hemp. "What I'm finding is that a lot of farmers in Wisconsin don't know what to do with their products," she said. "We tried to get a list of licensed farmers to help connect them with brokers, but the state wouldn't release that list."
Hi, I had ovarian cancer stage 2 and went to do chemotherapy for 16 times in 2014. It came back last year 2016 but I did not do chemotherapy or radiation therapy as suggested by the doctor. I am taking hormone therapy at the moment. I would like to use cannabis oil but which one and how much CBD and how much THC should I take for ovarian cancer? Can anyone give some idea?. Thank you very much.
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.
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.
By the 1930s, marijuana was banned in 24 states. The newly minted Federal Bureau of Narcotics launched a campaign against the drug, and newspapers fueled hysteria with headlines like the 1933 Los Angeles Examiner's "Murder Weed Found Up and Down the Coast — Deadly Marihuana Dope Plant Ready for Harvest That Means Enslavement of California Children." By 1937, Congress passed the Marihuana Tax Act, which effectively banned marijuana except for a few medicinal purposes, according to "Smoke Signals: A Social History of Marijuana – Medical, Recreational and Legal" (Scribner, 2012).

In the United States, the legality of medical marijuana varies in substantial ways from state to state. There are currently 29 US states with legal medical cannabis laws, as well as the District of Columbia. That leaves 21 states where medical marijuana is entirely prohibited. Marijuana cultivation, possession, and use in any form is illegal at the federal level.
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.
At least 50% of patients who receive moderately emetogenic chemotherapy may experience delayed chemotherapy-induced N/V. Although selective neurokinin 1 antagonists that inhibit substance P have been approved for delayed N/V, a study was conducted before their availability to assess dronabinol, ondansetron, or their combination in preventing delayed-onset chemotherapy-induced N/V.[34] Ondansetron, a serotonin 5-hydroxytryptamine 3 (5-HT3) receptor antagonist, is one of the mainstay agents in the current antiemetic armamentarium. In this trial, the primary objective was to assess the response 2 to 5 days after moderately to severely emetogenic chemotherapy. Sixty-one patients were analyzed for efficacy. The total response–a composite endpoint–including nausea intensity, vomiting/retching, and use of rescue medications, was similar with dronabinol (54%), ondansetron (58%), and combination therapy (47%) when compared with placebo (20%). Nausea absence was greater in the active treatment groups (dronabinol 71%, ondansetron 64%, combination therapy 53%) when compared with placebo (15%; P < .05 vs. placebo for all). Occurrence rates for nausea intensity and vomiting/retching episodes were the lowest in patients treated with dronabinol, suggesting that dronabinol compares favorably with ondansetron in this situation where a substance P inhibitor would currently be the drug of choice.
During the period from 1937 to the late 60s, the U.S. government understood and acknowledged that industrial hemp and marijuana were distinct varieties of the Cannabis plant. Hemp was no longer officially recognized as distinct from marijuana after the passage of the Controlled Substances Act (CSA) of 1970. This is despite the fact that a specific exemption for hemp was included in the CSA under the definition of marijuana. The recent federal court case HIA vs DEA has re-established acknowledgement of distinct varieties of Cannabis, and supports the exemption for non-viable seed and fiber and any products made from them.
The Montana Department of Agriculture is not responsible for a pilot participant’s business plan or activities and will not be a mediator between pilot participants and any business associates or partners.

Hemp seeds contain virtually no THC, but THC contamination results from contact of the seeds with the resin secreted by the epidermal glands on the leaves and floral parts, and also by the failure to sift away all of the bracts (which have the highest concentration of THC of any parts of the plant) that cover the seeds. This results in small levels of THC appearing in hempseed oil and foods made with the seeds. Although most of the western hemp-growing world uses 0.3% THC as a maximum concentration for authorized cultivation of hemp plants, regulations in various countries allow only a much lower level of THC in human food products manufactured from the seeds. Currently, up to 10 ppm THC is permitted in seeds and oil products used for food purposes in Canada. In Germany, more stringent limits were set for food in 2000: 5 ppm in food oil, 0.005 ppm in beverages, and 0.15 ppm in all other foods. The US Drug Enforcement Administration published new regulations on hemp in the Federal Register on October 9th 2001 that in effect 4 months later would ban the food use of hemp in the US because any amount of THC would be unacceptable in foods (follow links at www.hempreport.com/). These proposals are currently being challenged by the hemp industry. Limits have been set because of concerns about possible toxicity and interference with drug tests (Grotenhermen et al. 1998). An extensive analysis of literature dealing with the toxicity of hemp is in Orr and Starodub (1999; see Geiwitz 2001 for an analysis). Because hemp food products are considered to have great economic potential, there is considerable pressure on the hemp industry in North America to reduce THC levels.
There is a general inverse relationship in the resin of Cannabis between the amounts of THC present and the amount of the other principal cannabinoid, CBD. Whereas most drug strains contain primarily THC and little or no CBD, fiber and oilseed strains primarily contain CBD and very little THC. CBD can be converted to THC by acid catalyzed cyclization, and so could serve as a starting material for manufacturing THC. In theory, therefore, low-THC cultivars do not completely solve the problem of drug abuse potential. In practice, however, the illicit drug trade has access to easier methods of synthesizing THC or its analogues than by first extracting CBD from non-drug hemp strains.

Hemp oil has never been as popular as other marijuana products. With little to no THC, CBD-rich strains of cannabis don’t deliver the pleasant buzz recreational users seek out in marijuana. In the 1970s, however, scientists found that cannabidiol was effective in reducing seizures. The brain’s endocannabinoid system contains receptors that respond to CBD, producing anticonvulsant effects. Being plant-derived and native to the brain’s own chemistry, CBD is therefore one of the most natural options for seizure treatment available today. Still, not many people took interest in CBD until 2013, when a CNN documentary special, Weed, hosted by the network’s chief medical correspondent, Dr. Sanjay Gupta, highlighted CBD’s effectiveness in combating seizures. Since then, demand for hemp oil products has exploded.
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.
Medical marijuana refers to the use of the Cannabis plant as a physician-recommended herbal therapy as well as synthetic[181] THC and cannabinoids. So far, the medical use of cannabis is legal only in a limited number of territories, including Canada,[37] Belgium, Australia, the Netherlands, Spain, and many U.S. states. This usage generally requires a prescription, and distribution is usually done within a framework defined by local laws. There is evidence supporting the use of cannabis or its derivatives in the treatment of chemotherapy-induced nausea and vomiting, neuropathic pain, and multiple sclerosis. Lower levels of evidence support its use for AIDS wasting syndrome, epilepsy, rheumatoid arthritis, and glaucoma.[74]

The challenge to find lighter and longer-lasting energy storage devices (e.g., batteries) can be found in almost every sector. Hemp could prove to revolutionize battery life by aiding in the development of faster, smaller and cheaper supercapacitors. A supercapacitor is an energy storage device that can discharge powerful infusions of energy, needed only in small bursts. Such powerful discharges are used in braking systems of electric vehicles, the powering on of computers and new technologies such as rapid phone charging or cordless tools.
"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."

This may reflect the multitude of cognitive tasks employed by the various studies included in these meta-analyses, all of which involved performing a task thereby requiring the participant to reorient their attention and attempt to solve the problem at hand and suggest that greater engagement of this region indicates less efficient cognitive performance in cannabis users in general, irrespective of their age.

The environment in which hemp and marijuana are grown is strikingly different. Hemp is grown closely together (as close as 4 inches apart) and are typically grown in large multi-acre plots. It can also grow in variety of climates and its growth cycle is 108-120 days. Unlike hemp, marijuana requires a carefully controlled, warm, and humid atmostphere for proper growth. Its growth cycle only 60-90 days. Medical cannabis also cannot be grown too close to each other. They are typically grown 6 feet apart. If, somehow, marijuana grows among (or close to) a hemp field, the hemp’s pollen would immediateately ruin the marijuana crop, diluting marijuana’s psychoactivity.


Only a handful of countries have legalized recreational marijuana. Uruguay was one of the first, in 2013. The Netherlands is perhaps the country most known for legal marijuana, yet the drug is illegal there. Spain has given its citizens the rights to grow and consume cannabis privately. Peru also allows citizens to possess marijuana as long as it is for personal, private use. As in Costa Rica, where people can have a “small amount,” without legal trouble.
Indeed, hemp oil products have grown out of a market largely devoid of regulations or safety protocols. The state of the CBD industry harks back to the age of elixirs and potions hawked from covered wagons to the awed denizens of pioneer towns. There are no industrywide standards in place to ensure that CBD oils are consistently formulated batch-to-batch. There is no regulatory body screening products for pesticides, heavy metals, solvent residues, and other dangerous contaminants. The laboratories that companies contract to test their CBD products are themselves neither standardized nor consistently regulated. No medical research exists to recommend how much CBD a patient should take, nor is there detailed, reliable documentation of how CBD interacts with most epilepsy medications.
Following an 1836–1840 travel in North Africa and the Middle East, French physician Jacques-Joseph Moreau wrote on the psychological effects of cannabis use; Moreau was a member of Paris' Club des Hashischins (founded in 1844).[citation needed] In 1842, Irish physician William Brooke O'Shaughnessy, who had studied the drug while working as a medical officer in Bengal with the East India company, brought a quantity of cannabis with him on his return to Britain, provoking renewed interest in the West.[193] Examples of classic literature of the period featuring cannabis include Les paradis artificiels (1860) by Charles Baudelaire and The Hasheesh Eater (1857) by Fitz Hugh Ludlow.
By the 1930s, marijuana was banned in 24 states.

But, uh, what is it that CBD is supposed to do? I visited a cannabis dispensary in Boulder to find out what the hype was all about. After passing an ID check, I was introduced to a “budtender” who pointed me to an impressive array of CBD products — tinctures, skin patches, drink powders, candies, salves, massage oil, lotions, “sexy time personal intimacy oil” and even vaginal suppositories to treat menstrual cramps.
A cross-sectional survey of cancer patients seen at the Seattle Cancer Care Alliance was conducted over a 6-week period between 2015 and 2016.[18] In Washington State, Cannabis was legalized for medicinal use in 1998 and for recreational use in 2012. Of the 2,737 possible participants, 936 (34%) completed the anonymous questionnaire. Twenty-four percent of patients considered themselves active Cannabis users. Similar numbers of patients inhaled (70%) or used edibles (70%), with dual use (40%) being common. Non–mutually exclusive reasons for Cannabis use were physical symptoms (75%), neuropsychiatric symptoms (63%), recreational use/enjoyment (35%), and treatment of cancer (26%). The physical symptoms most commonly cited were pain, nausea, and loss of appetite. The majority of patients (74%) stated that they would prefer to obtain information about Cannabis from their cancer team, but less than 15% reported receiving information from their cancer physician or nurse.
exhaustion and pain that kept her on the couch much of the day. The 58-year-old Seattle speech coach didn’t want to take opioid pain-killers, but Tylenol wasn’t helping enough. Roth was intrigued when women in her online chat group enthused about a cannabis-derived oil called cannabidiol (CBD) that they said relieved pain without making them high. So Roth, who hadn’t smoked weed since college but lived in a state where cannabis was legal, walked into a dispensary and bought a CBD tincture. “Within a few hours of placing the drops in my mouth, the malaise and achiness that had plagued me for weeks lifted and became much more manageable,” she says. She took the drops several times a day and in a few weeks was back to her regular life.
As of March 2016, more than half of the 50 states have laws that allow for some hemp production, according to this chart. Yet, many states, such as California, where Jungmaven is based, will only allow for industrial hemp cultivation when federal law coincides with state law. That is, when Congress passes a bill permitting industrial hemp across the US. Currently, Jungmann imports his hemp from China, but he’s confident Congress will pass the bill legalizing industrial farming of hemp in July.

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.

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.
Millennia of selective breeding have resulted in varieties that display a wide range of traits; e.g. suited for a particular environments/latitudes, producing different ratios and compositions of terpenoids and cannabinoids (CBD, THC, CBG, CBC, CBN...etc.), fibre quality, oil/seed yield etc. Hemp grown for fiber is planted closely, resulting in tall, slender plants with long fibers.
