Separate levels of evidence scores are assigned to qualifying human studies on the basis of statistical strength of the study design and scientific strength of the treatment outcomes (i.e., endpoints) measured. The resulting two scores are then combined to produce an overall score. An overall level of evidence score cannot be assigned to cannabinoids because there has been insufficient clinical research. For an explanation of possible scores and additional information about levels of evidence analysis of CAM treatments for people with cancer, refer to Levels of Evidence for Human Studies of Integrative, Alternative, and Complementary Therapies.
In some areas where cannabis use had been historically tolerated, new restrictions were instituted, such as the closing of cannabis coffee shops near the borders of the Netherlands,[210] and closing of coffee shops near secondary schools in the Netherlands.[211] In Copenhagen, Denmark in 2014, mayor Frank Jensen discussed possibilities for the city to legalize cannabis production and commerce.[212]

Taking CBD oil is like drinking milk and calling it calcium, Hernandez said: There’s some in there, but at very low concentrations dispersed among a host of other ingredients. And what those other ingredients are is anyone’s guess. “The thing to know is that CBD hasn’t gone through the safety controls, the efficacy controls that we usually use, the clinical trials,” Hernandez said. “The jury is still out regarding how safe this drug is.”


“Hemp” refers primarily to Cannabis sativa L. (Cannabaceae), although the term has been applied to dozens of species representing at least 22 genera, often prominent fiber crops. For examples, Manila hemp (abaca) is Musa textilis Née, sisal hemp is Agave sisalina Perrine, and sunn hemp is Crotolaria juncea L. Especially confusing is the phrase “Indian hemp,” which has been used both for narcotic Asian land races of C. sativa (so-called C. indica Lamarck of India) and Apocynum cannabinum L., which was used by North American Indians as a fiber plant. Cannabis sativa is a multi-purpose plant that has been domesticated for bast (phloem) fiber in the stem, a multi-purpose fixed oil in the “seeds” (achenes), and an intoxicating resin secreted by epidermal glands. The common names hemp and marijuana (much less frequently spelled marihuana) have been applied loosely to all three forms, although historically hemp has been used primarily for the fiber cultigen and its fiber preparations, and marijuana for the drug cultigen and its drug preparations. The current hemp industry is making great efforts to point out that “hemp is not marijuana.” Italicized, Cannabis refers to the biological name of the plant (only one species of this genus is commonly recognized, C. sativa L.). Non-italicized, “cannabis” is a generic abstraction, widely used as a noun and adjective, and commonly (often loosely) used both for cannabis plants and/or any or all of the intoxicant preparations made from them.
For profitable hemp farming, particularly deep, humus-rich, nutrient-rich soil with controlled water flow is preferable. Waterlogged acidic, compressed or extremely light (sandy) soils primarily affect the early development of plants.[citation needed] Steep and high altitudes of more than 400 m above sea level are best avoided. Hemp is relatively insensitive to cold temperatures and can withstand frost down to −5 °C.[citation needed] Seeds can germinate down to 1–3 °C.[citation needed] Hemp needs a lot of heat, so earlier varieties come to maturation. The water requirement is 300–500 l/kg dry matter.[citation needed] This is around 1/14th that of cotton, which takes between 7,000 and 29,000 l/kg, according to WWF.[citation needed] Roots can grow up to 3 feet into the soil and use water from deeper soil layers.
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.
The woody core (hurds, sometimes called shives) of hemp makes remarkably good animal bedding (Fig. 28, 29). The hurds are sometimes molded into small pellets for bedding applications (Fig. 30). Such appears to be unsurpassed for horse bedding, and also make an excellent litter for cats and other pets (Fig. 31). The hurds can absorb up to five times their weight in moisture (typically 50% higher than wood shavings), do not produce dust (following initial dust removal), and are easily composted. Hemp bedding is especially suited to horses allergic to straw. In Europe, the animal bedding market is not considered important (Karus et al. 2000), but in North America there are insufficient hemp hurds available to meet market demand.

The endocannabinoid system is believed to be centrally involved in the regulation of mood and the extinction of aversive memories. Animal studies have shown CBD to have anxiolytic properties. It was shown in rats that these anxiolytic properties are mediated through unknown mechanisms.[52] Anxiolytic effects of CBD have been shown in several animal models.[53,54]


Hemp is completely different from marijuana in its function, cultivation and application. But these differences didn’t stop our political leaders from getting confused and accidentally grouping all Cannabis species as a Schedule I Drug and banning it in 1970 under the Controlled Substances Act. Even after 45 years, the government still seems to have some confusion in distinguishing the two plants. Although legislation is being made, progress has been slow.In its application, hemp and marijuana serve completely different purposes. Marijuana, as it is widely known, is used for medicinal or recreational purposes. Hemp is used in variety of other applications that marijuana couldn’t possibly be used in. These include healthy dietary supplements, skin products, clothing, and accessories. Overall, hemp is known to have over 25,000 possible applications.

Still, as the saying goes, absence of evidence isn’t necessarily evidence of absence, and there’s a reason we don’t have a ton of solid research on CBDs yet — “to study it, we need a good source, ” said Ziva Cooper, who is an associate professor at Columbia University and was on the National Academies committee. CBD is hard to get because it’s still technically a Schedule I drug, which limits its availability, Cooper said.
The high lipid-solubility of cannabinoids results in their persisting in the body for long periods of time.[131] Even after a single administration of THC, detectable levels of THC can be found in the body for weeks or longer (depending on the amount administered and the sensitivity of the assessment method).[131] A number of investigators have suggested that this is an important factor in marijuana's effects, perhaps because cannabinoids may accumulate in the body, particularly in the lipid membranes of neurons.[132]

CBD oil products are liquid drops of hemp which are taken orally. They are non-psychoactive and are available in low and high concentrations. Hemp oil tinctures are easy-to-use and offer all of the benefits associated with CBD. Hemp oil can be used sublingually via a dropper, or it can be added to your food and beverages which is why most customers have made it their go-to CBD product.
One of the biggest players in this new industry is Medical Marijuana, Inc., a company formed in 2009 that operates out of Poway, California, just north of San Diego. It has played a leading role in the so-called Green Rush, as businesses have moved quickly to capitalize on the gradual legalization of marijuana for medical and recreational purposes by states across the country. The company’s spokesman, Andrew Hard, boasted that Medical Marijuana, Inc., “created the CBD industry and was first to market with CBD products.” Through its various subsidiaries, Medical Marijuana, Inc. sells some of the most recognizable products on the cannabis market— everything from Cibaderm CBD-infused shampoo to CanChew chewing gum. In 2014, the company generated $14.5 million in revenue.
Neurologists are skilled at predicting side effects and interactions between well-researched pharmaceuticals. But due to the dearth of reliable research about CBD, doctors like Hernandez and Knupp cannot guide their patients in its use. If there are adverse reactions, Penny will find out because Harper will suffer through them. She has had to figure out through trial and error how best to mix and measure Harper’s oils. The bottom line, Penny said, is simple: “We are the research.”
In addition to positively affecting the endocannabinoid system, CBD has been the focus of more than 23,000 published studies about cannabinoids in relation to various medical indications including anxiety, epilepsy, inflammation, cancer and chronic pain to name few. For a more comprehensive look at these and other studies, visit our medical research and education page.

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

Marijuana and hemp both come from the same species of plant, Cannabis sativa. Once it was discovered the plant’s flowers can can have psychoactive effects, cultivators began growing separate strains of the plant – one normal variety, and one whose flowers contained higher levels of the cannabinoid tetrahydrocannabinol (THC), leading to tighter regulation.
Both in Canada and the US, the most critical problem to be addressed for commercial exploitation of C. sativa is the possible unauthorized drug use of the plant. Indeed, the reason hemp cultivation was made illegal in North America was concern that the hemp crop was a drug menace. The drug potential is, for practical purposes, measured by the presence of THC. THC is the world’s most popular illicit chemical, and indeed the fourth most popular recreational drug, after caffeine, alcohol, and nicotine. “Industrial hemp” is a phrase that has become common to designate hemp used for commercial non-intoxicant purposes. Small and Cronquist (1976) split C. sativa into two subspecies: C. sativa subsp. sativa, with less than 0.3% (dry weight) of THC in the upper (reproductive) part of the plant, and C. sativa subsp. indica (Lam.) E. Small & Cronq. with more than 0.3% THC. This classification has since been adopted in the European Community, Canada, and parts of Australia as a dividing line between cultivars that can be legally cultivated under license and forms that are considered to have too high a drug potential. For a period, 0.3% was also the allowable THC content limit for cultivation of hemp in the Soviet Union. In the US, Drug Enforcement Agency guidelines issued Dec. 7, 1999 expressly allowed products with a THC content of less than 0.3% to enter the US without a license; but subsequently permissible levels have been a source of continuing contention. Marijuana in the illicit market typically has a THC content of 5% to 10% (levels as high as 25% have been reported), and as a point of interest, a current Canadian government experimental medicinal marijuana production contract calls for the production of 6% marijuana. As noted above, a level of about 1% THC is considered the threshold for marijuana to have intoxicating potential, so the 0.3% level is conservative, and some countries (e.g. parts of Australia, Switzerland) have permitted the cultivation of cultivars with higher levels. It should be appreciated that there is considerable variation in THC content in different parts of the plant. THC content increases in the following order: achenes (excluding bracts), roots, large stems, smaller stems, older and larger leaves, younger and smaller leaves, flowers, perigonal bracts covering both the female flowers and fruits. It is well known in the illicit trade how to screen off the more potent fractions of the plant in order to increase THC levels in resultant drug products. Nevertheless, a level of 0.3% THC in the flowering parts of the plant is reflective of material that is too low in intoxicant potential to actually be used practically for illicit production of marijuana or other types of cannabis drugs. Below, the problem of permissible levels of THC in food products made from hempseed is discussed.
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.
A 2015 meta analysis found that, although a longer period of abstinence was associated with smaller magnitudes of impairment, both retrospective and prospective memory were impaired in cannabis users. The authors concluded that some, but not all, of the deficits associated with cannabis use were reversible.[114] A 2012 meta analyses found that deficits in most domains of cognition persisted beyond the acute period of intoxication, but was not evident in studies where subjects were abstinent for more than 25 days.[115] Few high quality studies have been performed on the long-term effects of cannabis on cognition, and results were generally inconsistent.[116] Furthermore, effect sizes of significant findings were generally small.[115] One review concluded that, although most cognitive faculties were unimpaired by cannabis use, residual deficits occurred in executive functions.[117] Impairments in executive functioning are most consistently found in older populations, which may reflect heavier cannabis exposure, or developmental effects associated with adolescent cannabis use.[118] One review found three prospective cohort studies that examined the relationship between self reported cannabis use and intelligence quotient (IQ). The study following the largest number of heavy cannabis users reported that IQ declined between ages 7–13 and age 38. Poorer school performance and increased incidence of leaving school early were both associated with cannabis use, although a causal relationship was not established.[110] Cannabis users demonstrated increased activity in task-related brain regions, consistent with reduced processing efficiency.[119]
The applicant, including all corporate officers, must be fingerprinted at a law enforcement agency. The law enforcement agency, not the applicant, must send the fingerprint sheet to the Department (80-18-103, MCA). Most local law enforcement offices provide fingerprinting services. The completed application and copy of the law enforcement submitted fingerprints will be submitted for DEA review and approval. The DEA may place additional requirements on the Department or the applicant for participation or continuation of the program. At the end of the licensure, program participants must submit an agricultural/agronomic report regarding their experience with their hemp crop. The report shall include the approximate yield in pounds per acre and the method used to devitalize the seed. All seed must be devitalized after harvest and no seed production for future planting is allowed under the Montana Industrial Hemp Pilot Program.
The Department has policies and procedures in place for the commonwealth's hemp research program, which can be found in the 2019 Pilot Program Parameters. Researchers from institutions of higher education or growers who would like to be considered for participation in the 2019 program must submit a 2019 PDA Industrial Hemp Research Pilot Program Permit Application prior to the application deadline of December 17, 2018. Researchers who participated in the 2018 Pilot Program may submit a Permit Renewal form by December 17, 2018 to continue their projects in the 2019 growing season.

In Japan, hemp was historically used as paper and a fiber crop. There is archaeological evidence cannabis was used for clothing and the seeds were eaten in Japan back to the Jōmon period (10,000 to 300 BC). Many Kimono designs portray hemp, or asa (Japanese: 麻), as a beautiful plant. In 1948, marijuana was restricted as a narcotic drug. The ban on marijuana imposed by the United States authorities was alien to Japanese culture, as the drug had never been widely used in Japan before. Though these laws against marijuana are some of the world's strictest, allowing five years imprisonment for possession of the drug, they exempt hemp growers, whose crop is used to make robes for Buddhist monks and loincloths for Sumo wrestlers. Because marijuana use in Japan has doubled in the past decade, these exemptions have recently been called into question.[143]

Cannabidiol has been found to act as an antagonist of GPR55, a G protein-coupled receptor and putative cannabinoid receptor that is expressed in the caudate nucleus and putamen in the brain.[35] It has also been found to act as an inverse agonist of GPR3, GPR6, and GPR12.[12] Although currently classified as orphan receptors, these receptors are most closely related phylogeneticaly to the cannabinoid receptors.[12] In addition to orphan receptors, CBD has been shown to act as a serotonin 5-HT1A receptor partial agonist,[36] and this action may be involved in its antidepressant,[37][38] anxiolytic,[38][39] and neuroprotective effects.[40][41] It is an allosteric modulator of the μ- and δ-opioid receptors as well.[42] The pharmacological effects of CBD have additionally been attributed to PPARγ agonism and intracellular calcium release.[8]
Short-term use increases both minor and major adverse effects.[103] Common side effects include dizziness, feeling tired, vomiting, and hallucinations.[103] Long-term effects of cannabis are not clear.[105] Concerns including memory and cognition problems, risk of addiction, schizophrenia in young people, and the risk of children taking it by accident.[102]
No ongoing clinical trials of Cannabis as a treatment for cancer in humans were identified in a PubMed search. The only published trial of any cannabinoid in patients with cancer is a small pilot study of intratumoral injection of delta-9-THC in patients with recurrent glioblastoma multiforme, which demonstrated no significant clinical benefit.[19,20] In a trial (NCT02255292) conducted in Israel, oral cannabidiol (CBD) was investigated as a single salvage agent for recurrent solid tumors. The study was projected to be completed in 2015; however, no results have been published. A small exploratory phase II study (GWCA1208 Part A [NCT01812603]) was conducted in the United Kingdom that used nabiximols, a 1:1 ratio of THC:CBD in a Cannabis-based medicinal extract oromucosal spray, in conjunction with temozolomide in treating patients with recurrent glioblastoma multiforme. The study enrolled 21 patients. Final results have not been published.
The Cannabis plant has a history of medicinal use dating back thousands of years across many cultures.[110] The Yanghai Tombs, a vast ancient cemetery (54 000 m2) situated in the Turfan district of the Xinjiang Uyghur Autonomous Region in northwest China, have revealed the 2700-year-old grave of a shaman. He is thought to have belonged to the Jushi culture recorded in the area centuries later in the Hanshu, Chap 96B.[111] Near the head and foot of the shaman was a large leather basket and wooden bowl filled with 789g of cannabis, superbly preserved by climatic and burial conditions. An international team demonstrated that this material contained tetrahydrocannabinol, the psychoactive component of cannabis. The cannabis was presumably employed by this culture as a medicinal or psychoactive agent, or an aid to divination. This is the oldest documentation of cannabis as a pharmacologically active agent.[112]

After fighting the effects of thyroid cancerfor 12 years I wanted to die. Every day. Now, please understand that these were thoughts with no actions, I was just miserable in pain.After 1 week on the CBD oil, (5 drops under the toungue 2x per day) I am a different woman. I now have hope. Some of my emotional pain is presenting as physical pain, but IT'S LEAVING MY BODY.
Despite its designation as having no medicinal use, Cannabis was distributed by the U.S. government to patients on a case-by-case basis under the Compassionate Use Investigational New Drug program established in 1978. Distribution of Cannabis through this program was closed to new patients in 1992.[1-4] Although federal law prohibits the use of Cannabis, Figure 1 below shows the states and territories that have legalized Cannabis use for medical purposes. Additional states have legalized only one ingredient in Cannabis, such as cannabidiol (CBD), and are not included in the map. Some medical marijuana laws are broader than others, and there is state-to-state variation in the types of medical conditions for which treatment is allowed.[7]

In Europe and Asia, hemp farming has been conducted for millennia. Although most countries ceased growing hemp after the second word war, some didn’t, including France, China, Russia, and Hungary, so that essential knowledge of how to grow and process hemp was maintained. When commercial hemp cultivation resumed in Canada in 1997, many farmers undertook to grow the crop without appreciating its suitability for their situation, or for the hazards of an undeveloped market. Hemp was often grown on farms with marginal incomes in the hopes that it was a savior from a downward financial spiral. The myth that hemp is a wonder crop that can be grown on any soil led some to cultivate on soils with a history of producing poor crops; of course, a poor crop was the result.
In the 1970s, President Nixon declared a “War on Drugs” and signed into law the Controlled Substances Act of 1970. This law established a set of banned drugs and created the Drug Enforcement Administration (DEA). It also unintentionally outlawed one of the world’s oldest domesticated crop, hemp. This not only led to the demise of hemp, but also an increased misconception of the plant.
I have had several neurological conditions like Bells Palsy three times, double vision, paralysis of left side of tongue. I have a lot of relief whenever I have pain by taking an inflamattory drug etoshine90 mg. Presently I have started taking Steroids for my facial palsy. The various pains I was having on the left side of neck, below the left ear, dizziness, pain around the head have subsided immidiately after the first dose of prendisolone 60 mg.I have read that CBD hemp oil can be useful for my condition of neurological and inflammation issues. My question is what concentrate (mg) of the oil should I take and for how long. Any brand that you may suggest that are available in the UK. Thank you.
An observational study assessed the effectiveness of nabilone in advanced cancer patients who were experiencing pain and other symptoms (anorexia, depression, and anxiety). The researchers reported that patients who used nabilone experienced improved management of pain, nausea, anxiety, and distress when compared with untreated patients. Nabilone was also associated with a decreased use of opioids, nonsteroidal anti-inflammatory drugs, tricyclic antidepressants, gabapentin, dexamethasone, metoclopramide, and ondansetron.[56]
The potential benefits of medicinal Cannabis for people living with cancer include antiemetic effects, appetite stimulation, pain relief, and improved sleep.[2] Although few relevant surveys of practice patterns exist, it appears that physicians caring for cancer patients in the United States who recommend medicinal Cannabis do so predominantly for symptom management.[3] A growing number of pediatric patients are seeking symptom relief with Cannabis or cannabinoid treatment, although studies are limited.[4] The American Academy of Pediatrics has not endorsed Cannabis and cannabinoid use because of concerns about brain development.
Success stories like Oliver’s are everywhere, but there’s not a lot of data to back up those results. That’s because CBD comes from cannabis and, like nearly all other parts of the plant, is categorized by the Drug Enforcement Agency (DEA) as a Schedule 1 drug—the most restrictive classification. (Others on that list: heroin, Ecstasy, and peyote.) This classification, which cannabis advocates have tried for years to change, keeps cannabis-derived products, including CBD, from being properly studied in the U.S.
Cement (Concrete) and Plaster. Utilizing the ancient technique of reinforcing clay with straw to produce reinforced bricks for constructing domiciles, plant fibers have found a number of comparable uses in modern times. Hemp fibers added to concrete increase tensile strength while reducing shrinkage and cracking. Whole houses have been made based on hemp fiber (Fig. 24, 25). In North America, such usage has only reached the level of a cottage industry. Fiber-reinforced cement boards and fiber-reinforced plaster are other occasionally produced experimental products. Hemp fibers are produced at much more cost than wood chips and straw from many other crops, so high-end applications requiring high strength seem most appropriate.
Ten trials have evaluated the efficacy of inhaled Cannabis in chemotherapy-induced N/V.[35-38] In two of the studies, inhaled Cannabis was made available only after dronabinol failure. In the first trial, no antiemetic effect was achieved with marijuana in patients receiving cyclophosphamide or doxorubicin,[35] but in the second trial, a statistically significant superior antiemetic effect of inhaled Cannabis versus placebo was found among patients receiving high-dose methotrexate.[36] The third trial was a randomized, double-blind, placebo-controlled, crossover trial involving 20 adults in which both inhaled marijuana and oral THC were evaluated. One-quarter of the patients reported a favorable antiemetic response to the cannabinoid therapies. This latter study was reported in abstract form in 1984. A full report, detailing the methods and outcomes apparently has not been published, which limits a thorough interpretation of the significance of these findings.[37]
For patients suffering from seizures, the legalization of cannabis would be a decisive turning point. Epilepsy makes you desperate. Seizures are painful, sometimes debilitating. And then there are the aftershocks: broken teeth, bruises and cuts, lost time, humiliation. People with epilepsy are often depressed, and have more than double the suicide rate of the population at large. Epilepsy is also associated with a syndrome known as Sudden Unexpected Death in Epilepsy, wherein a previously healthy person with epilepsy simply dies without warning or explanation. Grinding on without relief isn’t an option, but getting help is enormously expensive. Research conducted by Charles Begley, a professor of public health at the University of Texas, found that epilepsy treatment costs between $8,500 and $11,000 per year. Real Scientific Hemp Oil is no less expensive than its pharmaceutical counterparts, with no assistance from insurance. A single three-gram vial costs $149, while a six-pack of 10-gram tubes can cost $1,999 (or $1,599 on sale). HempMedsPx suggests a “serving size” of 0.5 ml twice daily. Only when these drugs are recognized as such will insurance pick up the tab.

The International Journal on Drug Policy. 21 (1): 10–9. doi:10.1016/j.drugpo.2009.09.001. PMID 19783132. The contentious issue of whether cannabis use can cause serious psychotic disorders that would not otherwise have occurred cannot be answered based on the existing data
A 2015 review found that the use of high CBD-to-THC strains of cannabis showed significantly fewer positive symptoms such as delusions and hallucinations, better cognitive function and both lower risk for developing psychosis, as well as a later age of onset of the illness, compared to cannabis with low CBD-to-THC ratios.[267] A 2014 Cochrane review found that research was insufficient to determine the safety and efficacy to using cannabis to treat schizophrenia or psychosis.[268] As of 2017, the molecular mechanisms for the anti-inflammatory and possible pain relieving effects of cannabis are under preliminary research.[269]
Based on studies of sex reversal in hemp, it was first reported by K. Hirata in 1924 that an XY sex-determination system is present.[25] At the time, the XY system was the only known system of sex determination. The X:A system was first described in Drosophila spp in 1925.[28] Soon thereafter, Schaffner disputed Hirata's interpretation,[29] and published results from his own studies of sex reversal in hemp, concluding that an X:A system was in use and that furthermore sex was strongly influenced by environmental conditions.[26]

Recreational cannabis use centers around one chemical: the psychoactive cannabinoid tetrahydrocannabinol (THC). Consuming this chemical induces euphoric and stimulating sensations commonly referred to as a “high.” For most marijuana users, these sensations are pleasurable and enjoyable. For some, however, THC can induce feelings of anxiety and paranoia, especially in large doses.


Most pro-hemp initiatives in the United States are now focused on defining and distinguishing between industrial hemp and marijuana. Some pro-hemp supporters would like to move the control of U.S. hemp production from the DEA to the USDA. Proponents of legalizing hemp also argue that new technology to distinguish THC levels both in the field and from the air will allow for adequate production enforcement.

Our award-winning support staff, experienced cultivators, and network of healthcare practitioners are here to help remove barriers to medical cannabis. We’re honoured to be part of a movement that’s helping Canadians across the country access their medicine; and as we grow we will continue to provide patients with reliable access to safe, consistent, and effective medical cannabis.
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.
Two studies examined the effects of oral delta-9-THC on cancer pain. The first, a double-blind, placebo-controlled study involving ten patients, measured both pain intensity and pain relief.[50] It was reported that 15 mg and 20 mg doses of the cannabinoid delta-9-THC were associated with substantial analgesic effects, with antiemetic effects and appetite stimulation.

In early June, I met with Penny Pennington Howard, a mother of three, who lives in Carrollton, Texas, about 25 minutes outside of Dallas. Posted in the glass of her front door are two signs you can’t quite make out from the sidewalk: one asking visitors not to smoke, as oxygen treatments are in use; the other a yellow diamond informing guests this is the home of a special needs child. Penny welcomed me inside, out of the glare of the sun, and led me through her living room into her kitchen, where her kids were gathered for lunch. Seth, then eight months old, was plucking cereal off the tray of his highchair, while Lily, seven, was darting back and forth between the countertop and table. Harper, a blond five-year-old with hot pink toenails, was reclining in her “tomato chair,” a molded plastic seat with straps to help keep her steady.
An analysis of 84,170 participants in the California Men’s Health Study was performed to investigate the association between Cannabis use and the incidence of bladder cancer. During 16 years of follow-up, 89 Cannabis users (0.3%) developed bladder cancer compared with 190 (0.4%) of the men who did not report Cannabis use (P < .001). After adjusting for age, race, ethnicity, and body mass index, Cannabis use was associated with a 45% reduction in bladder cancer incidence (hazard ratio, 0.55; 95% confidence interval, 0.33–1.00).[16]
In the U.S., we live in a culture where more is often perceived as being better.  And it’s easy, without even thinking about it, to apply that approach to CBD dosing. But when it comes to CBD, more is not necessarily better. In fact, for many, less CBD is more effective. One way to determine your optimal dosage is to start with a small amount of CBD for a couple weeks and then slowly increase your dosage, carefully taking note of symptoms, until you’re seeing the results you want.
An industrial hemp license issued by the state provides authorization for the production of industrial hemp at a particular growing area by a particular individual or entity. Licenses will expire on the last day of December of the year that they are issued. Renewals do not require new fingerprinting unless the department requests it or if the corporate officers have changed.
Despite the fact that marijuana remains illegal at the federal level, companies like HempMedsPx claim their CBD products are legal in all 50 states. According to a legal opinion written by Medical Marijuana, Inc.’s attorney and submitted to the New Republic, “HempMedsPx’s CBD hemp oil, containing naturally occurring CBD and miniscule amount of THC, is exempted from the definition of marijuana, is not a controlled substance, complies with the Controlled Substances Act, and is legal on the federal level.” The opinion is based in large part on a 2004 court ruling which allowed the importation of hemp food products derived from the mature stalks of cannabis plants.
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]

The objectivity of scientific evaluation of the medicinal value of marijuana to date has been questioned. In the words of Hirst et al. (1998): “The ...status of cannabis has made modern clinical research almost impossible. This is primarily because of the legal, ethical and bureaucratic difficulties in conducting trials with patients. Additionally, the general attitude towards cannabis, in which it is seen only as a drug of abuse and addiction, has not helped.” In a recent editorial, the respected journal Nature (2001) stated: “Governments, including the US federal government, have until recently refused to sanction the medical use of marijuana, and have also done what they can to prevent its clinical testing. They have defended their inaction by claiming that either step would signal to the public a softening of the so-called ‘war on drugs.’... The pharmacology of cannabinoids is a valid field of scientific investigation. Pharmacologists have the tools and the methodologies to realize its considerable potential, provided the political climate permits them to do so.” Given these current demands for research on medicinal marijuana, it will be necessary to produce crops of drug types of C. sativa.
Cannabis has held sacred status in several religions. It has been used in an entheogenic context – a chemical substance used in a religious, shamanic, or spiritual context[59] - in the Indian subcontinent since the Vedic period dating back to approximately 1500 BCE, but perhaps as far back as 2000 BCE. There are several references in Greek mythology to a powerful drug that eliminated anguish and sorrow. Herodotus wrote about early ceremonial practices by the Scythians, thought to have occurred from the 5th to 2nd century BCE. In modern culture the spiritual use of cannabis has been spread by the disciples of the Rastafari movement who use cannabis as a sacrament and as an aid to meditation. The earliest known reports regarding the sacred status of cannabis in the Indian subcontinent come from the Atharva Veda estimated to have been written sometime around 2000–1400 BCE.[60]
Today he sells numerous hemp-made items, from shoes to shirts, as well as a range of hemp-based health and medicinal products. After some productive networking at recent cannabis conventions, he's also in talks with Julian Marley to distribute his products around the country, and hopes to help bring a full-scale hemp festival — codename Hemp Hop — to New Orleans next year.
Today, dozens of companies produce CBD in an array of forms. CBD can be inhaled through vape pens, applied in topical salves, ingested in edibles, or swallowed in oil-based tinctures. Oil has become the dominant CBD delivery method for kids with epilepsy, since it is easy to administer and ingest, and there is no shortage of it available for sale online. There are dozens of companies boasting names like Healthy Hemp Oil, Dose of Nature, and Natural Organic Solutions, each of them selling CBD products at prices ranging from trivial to dizzyingly steep. You don’t have to look hard to find them. If you have a PayPal account and $100 to spare, you could have a vial of hemp oil delivered to your doorstep.

I am currently going through red skin syndrome/topical steroid withdrawal. The only cure as of now is time(6 months to 3 years) and waiting out horrible eczema-like flares. My main issue is burning/tingling skin that is almost constant. Steroids close off blood vessels and when you stop them they 'wake' up causing this nerve discomfort/pain. I've been smoking medical cannabis for the duration of my recovery(1.5 years) and It's done wonders except that the flare is around my mouth and I'm afraid the smoking is causing more issues.. as well as helping. I need to step up my game and take a different approach. I am wondering how to go about using cbd but I don't know where to start and was wondering if you could help. Thank you
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.

Given its name, you might assume THCV shares psychoactive powers with its potent counterpart, THC. In reality, this cannabinoid is more like a cross between CBD and THC. From the former, it takes its modulating powers. Acting like THC “lite,” THCV like CBD can dampen the effects of a strong high. Yet at higher doses, THCV kicks into a psychoactive stimulant in its own right.
CBD interacts with the body through the endogenous cannabinoid system (ECS) or endocannabinoid system. First discovered in the late 1980’s, the endocannabinoid system regulates the body’s homeostasis, or general state of balance, impacting such functions as mood, sleep, appetite, hormone regulation, and pain and immune response. Like an acrobat on a highwire, as the environment around us impacts our normal balance, the endocannabinoid system “corrects” by mediating our body’s reaction to keep us level.
Concerned about Mykayla’s stomach cramps, Krenzler, who lives in Portland, Oregon, sent a sample of the oil off to Going Green Labs in Albany, Oregon. Like most labs catering to the cannabis industry, Going Green mainly performs THC potency tests. According to Krenzler, when the lab tested his sample, it found that the Real Scientific Hemp Oil contained much more THC than HempMedsPx had claimed—3.8 percent, instead of roughly 1 percent. Krenzler said he was “disturbed” by the finding, and also by the implications it had for other parents of sick children. Medical marijuana is legal in Oregon, but Krenzler noted that in other states that have not legalized pot, anyone purchasing a product with more than a trace amount of THC could find themselves in legal jeopardy. “I feel that HempMeds had misrepresented their product,” Krenzler said.

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.
Although CBD oils aren’t regulated by the FDA, purchasing products stateside from one of the nine states where recreational and medical cannabis use is legal will likely result in a higher-quality product than buying one made with hemp-derived CBD oil imported from abroad, says Martin Lee, director of Project CBD, a nonprofit that promotes medical research into CBD.
Hemp rope was used in the age of sailing ships, though the rope had to be protected by tarring, since hemp rope has a propensity for breaking from rot, as the capillary effect of the rope-woven fibers tended to hold liquid at the interior, while seeming dry from the outside.[42] Tarring was a labor-intensive process, and earned sailors the nickname "Jack Tar". Hemp rope was phased out when Manila, which does not require tarring, became widely available. Manila is sometimes referred to as Manila hemp, but is not related to hemp; it is abacá, a species of banana.
