For many, the medical and therapeutic potential of cannabis is what makes legalizing the marijuana plant such an important political and social task. Federal prohibition has established barriers to comprehensive cannabis research in the United States. However, researchers in other countries continue to make significant contributions to our knowledge of the cannabis plant and how it affects the human body.


Cannabinoid agonists produce many effects beyond those mediated directly on receptors, including anti-inflammatory effects and interactions with various other neurotransmitter systems (previously reviewed (Russo 2006a). Briefly stated, THC effects in serotonergic systems are widespread, including its ability to decrease 5-hydroxytryptamine (5-HT) release from platelets (Volfe et al 1985), increase its cerebral production and decrease synaptosomal uptake (Spadone 1991). THC may affect many mechanisms of the trigeminovascular system in migraine (Akerman et al 2003; Akerman et al 2004; Akerman et al 2007; Russo 1998; Russo 2001). Dopaminergic blocking actions of THC (Müller-Vahl et al 1999) may also contribute to analgesic benefits.

To my understanding, neither CBD nor THC are effective for “severe” pain; rather, they work better for mild to moderate chronic pain. Often, with severe pain, the dosage of opiates can be decreased with concomitant use of medical cannabis or CBD and that decrease in dose makes their use safer. Concurrent use of THC does increase the analgesic effect of CBD, but it also adds the “high” which some people do not want as a side effect.

While very few clinical trials have explored the pain-relieving effects of CBD oil, a report published in the Cochrane Database of Systematic Reviews in 2018 examined the use of a variety of cannabis-based medicines and found they might be of some benefit in the treatment of chronic neuropathic pain. A type of pain triggered by damage to the somatosensory system (i.e., the system responsible for processing sensory stimuli), neuropathic pain often occurs in people with conditions like diabetes and multiple sclerosis.
I wouldn’t recommend the Lord Jones cream for deep tissue pain so much as surface-level aches: When I’m feeling pain on the pads of my feet, I rub a pump or two of this stuff on the area, which feels almost like applying lidocaine, except the lotion smells danker. My mother, who’s morally opposed to anything remotely weed-related, even took to it after I slipped her some for her painful, cracked winter hands. When I explained later what CBD was, she said, “Oh,” and after a beat, “I guess I did wonder why I stopped feeling anything.”

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.

Some important cannabinoids of cannabis resin. D9-THC (delta-9 tetrahydrocannabinol) is the chief intoxicant chemical and predominates in intoxicant strains, while the isomer D8-THC is usually present in no more than trace amounts. CBD (cannabidiol) is the chief non-intoxicant chemical, and predominates in non-intoxicant strains; it has sedative effects. The non-intoxicant CBN (cannabinol) is a frequent degradation or oxidation product. The non-intoxicant cannabichromene (CBC) is typically found in trace amounts in intoxicant strains. The non-intoxicant cannabigerol (CBG) is considered to be a precursor of the other cannbinoids (see Fig. 10). 

Interactions between medications are very common, especially in elderly populations that medicate for pain, diabetes and high cholesterol. The geriatric population is also the fastest-growing group of medical cannabis users. Cannabis has demonstrated efficacy in treating pain, and some phytocannabinoids have been suggested for various metabolic conditions. Thus it is important to understand how... Read more

In September 2018, following its approval by the FDA for rare types of childhood epilepsy,[13] Epidiolex was rescheduled (by the Drug Enforcement Administration) as a Schedule V drug to allow for its prescription use.[14] This change applies only to FDA-approved products containing no more than 0.1 percent THC.[14] This allows GW Pharmaceuticals to sell Epidiolex, but it does not apply broadly and all other CBD-containing products remain Schedule I drugs.[14] Epidiolex still requires rescheduling in some states before it can be prescribed in those states.[65][66]
I have a brother in law who has been diagnosed with cataplexy and narcoplexy, where he starts quivering and slowly loses control of his body and goes into a sleep, which causes him to drop to the ground with mild seizures while he is out. He lives alone (59 years old), but has smoked cannabis since he (we) were teenagers. He still smokes, and is on medication twice a day for this condition, but if he misses those meds by even half an hour, he is at risk of these seizures. The sad part is, these seizures are usually brought on by the smallest emotional change, usually tension, excitement or, the worst thing, if something he finds funny and is the least bit tickled about and starts to laugh, this process will immediately begin. Does anyone know if this kind of condition is treatable with cbd oil’s or concentrates? As I said, he smokes weed, and often grows his own, but he does it for the high and relaxation advantage, since he is basically home-bound due to this condition ending his work career about 4 years ago. Thanks for any replies. I’d be overjoyed if I could tell him there’s a possible solution to the problem other than his prescriptions. Or even if it worked WITH his meds to keep from having to live such a sedentary life.
Donald Abrams was a member of the committee that reviewed the evidence that went into producing the report, and he said that the studies they reviewed overwhelmingly used pharmaceutically available preparations that contain THC, including dronabinol, nabilone and the whole-plant extract spray nabiximols, which contains equal parts CBD and THC. It’s impossible to know whether the benefits of cannabis can also be obtained from CBD alone, Abrams said, because CBD is just one of 400 chemicals present in the plant. So far, CBD in isolation has been studied in only a handful of randomized, placebo-controlled trials (considered the gold standard of evidence in medical research), and the evidence remains sparse.
Personal health also depends partially on the social structure of a person's life. The maintenance of strong social relationships, volunteering, and other social activities have been linked to positive mental health and also increased longevity. One American study among seniors over age 70, found that frequent volunteering was associated with reduced risk of dying compared with older persons who did not volunteer, regardless of physical health status.[58] Another study from Singapore reported that volunteering retirees had significantly better cognitive performance scores, fewer depressive symptoms, and better mental well-being and life satisfaction than non-volunteering retirees.[59]

Carbon dioxide is passed through the plant material at a very specific temperature and pressure. Carbon dioxide, which is normally a gas at (or above) room temperature, can be pressurized until it becomes so dense that it takes on some of the properties of a liquid while still maintaining the fluid dynamics of a gas. In this state, CO2 is known as a supercritical fluid.
Medical cannabis (or medical marijuana) refers to the use of cannabis and its constituent cannabinoids, to treat disease or improve symptoms. Cannabis is used to reduce nausea and vomiting during chemotherapy, to improve appetite in people with HIV/AIDS, and to treat chronic pain and muscle spasms.[103][104] Cannabinoids are under preliminary research for their potential to affect stroke.[105]

CBD stands for cannabidiol. It is the second most prevalent of the active ingredients of cannabis (marijuana). While CBD is an essential component of medical marijuana, it is derived directly from the hemp plant, which is a cousin of the marijuana plant. While CBD is a component of marijuana (one of hundreds), by itself it does not cause a “high.” According to a report from the World Health Organization, “In humans, CBD exhibits no effects indicative of any abuse or dependence potential…. To date, there is no evidence of public health related problems associated with the use of pure CBD.”
Despite the fact that Cannabis was grown on a large scale in many countries, the abuse as a narcotic remained uncommon in Western countries until relatively recently. People were largely unaware of the psychoactive properties of Cannabis and it is unlikely that early cultivars, selected mainly for their seed or fiber qualities, contained significant amounts of the psychoactive THC. The medicinal use of Cannabis was introduced in Europe only around 1840, by a young Irish doctor, William O’Shaughnessy, who served for the East India Trading Company in India, where the medicinal use of Cannabis was widespread. Unlike the European fiber Cannabis, these Indian varieties did contain a reasonable amount of bioactive cannabinoids. In the following decades, the medicinal use of Cannabis saw a short period of popularity both in Europe and in the United States. At the top of its popularity, more than 28 different medicinal preparations were available with Cannabis as active ingredient, which were recommended for indications as various as menstrual cramps, asthma, cough, insomnia, support of birth labor, migraine, throat infection, and withdrawal from opium use.27
We tested more than 20 different CBD oil products in our search to find the best CBD oil for pain. Some of them are pretty good products, some just do almost nothing to manage pain symptoms, either chronic pain or acute pain after injures. But 7 of them, great products with high potency and effectiveness against different types of pain, we included in our top list.

A chief argument that has been advanced in favor of developing hemp as a paper and pulp source has been that as a non-wood or tree-free fiber source, it can reduce harvesting of primary forests and the threat to associated biodiversity. It has been claimed that hemp produces three to four times as much useable fiber per hectare per annum as forests. However, Wong (1998) notes evidence that in the southern US hemp would produce only twice as much pulp as does a pine plantation (but see discussion below on suitability of hemp as a potential lumber substitute in areas lacking trees).

The dense growth of hemp eliminates other weeds.... The best growing technique for hemp, planting 300 to 500 plants per square meter, also helps authorities easily tell the hemp from marijuana, which is a plant that is less densely cultivated.

"No official estimates are available of the value of U.S. sales of hemp-based products. The Hemp Industries Association (HIA) reports total U.S. retail sales of hemp products of nearly $700 million in 2016,12 which includes food and body products, dietary supplements, clothing, auto parts, building materials, and other consumer products (Figure 2). HIA claims that U.S. hemp retail sales have increased by about 10% to more than 20% annually since 2011. Much of this growth is attributable to sales of hemp-based body products, supplements, and foods. Combined, these categories accounted for more than two-thirds of the value of U.S. retail sales in 2016.
A bit of online digging led me to realize that the active ingredient in Charlotte's Web Everyday Plus Hemp Oil, the product I'd been offered to test, was the chemical compound CBD, which stands for Cannabidiol. Unlike THC, the other crucial compound in hemp and marijuana plants, CBD does not produce the psychoactive effects that make you feel "high"; instead, it actually eases anxiety and makes you less likely to freak out.

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.
CBD stands for cannabidiol, one of the major constituents of cannabis. CBD products are made from industrial hemp and come in various forms. Although hemp and cannabis are in the same plant species, CBD products now on the market contain less than 0.3 percent THC (tetrahydrocannabinol), the cannabis compound that gets you high. CBD oil can be mixed into food, either straight or diluted with cooking oil, or it can be heated and its vapors inhaled. You can buy CBD in capsules, liquids, gummies, and sublingual sprays, and it is added to tea, coffee, and smoothies. Business experts estimate that the market for CBD products will reach more than $2 billion in consumer sales in the U.S. within the next four years.
Cannabis most likely originates from Central Asia, as archeological evidence indicates that it was already cultivated in China for food and fiber 10 000 years ago. Even in ancient Egyptian mummies, clues have been found for the use of Cannabis as food or medicine.25 In fact, Cannabis is one of the oldest known medicinal plants and is described in almost every ancient handbook on plant medicine, most commonly in the form of a tincture or a tea.26,27 Some religions were closely related with the properties of the Cannabis plant. For example, in Hindu legend, Cannabis is believed to be the favorite food of the god Shiva, because of its energizing properties. As Cannabis spread from Asia toward the West, almost every culture came into contact with this miracle plant. Nowadays, varieties of Cannabis can be found in all temperate and tropical zones, except in humid, tropical rain forests.28

Buying online is less reliable still because there’s no regulation or standardization. What you see on the label may not be what you are getting. A 2017 study in JAMA found that of the 84 CBD products researchers bought online, 43% had more CBD than indicated, while 26% had less, and some had unexpected THC. “There’s a 75% chance of getting a product where the CBD is mislabeled,” says Marcu, one of the study’s coauthors.
Cannabinoids may offer significant “side benefits” beyond analgesia. These include anti-emetic effects, well established with THC, but additionally demonstrated for CBD (Pertwee 2005), the ability of THC and CBD to produce apoptosis in malignant cells and inhibit cancer-induced angiogenesis (Kogan 2005; Ligresti et al 2006), as well as the neuroprotective antioxidant properties of the two substances (Hampson et al 1998), and improvements in symptomatic insomnia (Russo et al 2007).
The etymology is uncertain but there appears to be no common Proto-Indo-European source for the various forms of the word; the Greek term kánnabis is the oldest attested form, which may have been borrowed from an earlier Scythian or Thracian word.[9][10] Then it appears to have been borrowed into Latin, and separately into Slavic and from there into Baltic, Finnish, and Germanic languages.[11] Following Grimm's law, the "k" would have changed to "h" with the first Germanic sound shift,[9][12] after which it may have been adapted into the Old English form, hænep. However, this theory assumes that hemp was not widely spread among different societies until after it was already being used as a psychoactive drug, which Adams and Mallory (1997) believe to be unlikely based on archaeological evidence.[9] Barber (1991) however, argued that the spread of the name "kannabis" was due to its historically more recent drug use, starting from the south, around Iran, whereas non-THC varieties of hemp are older and prehistoric.[11] Another possible source of origin is Assyrian qunnabu, which was the name for a source of oil, fiber, and medicine in the 1st millennium BC.[11]
Epidiolex is the first FDA-approved treatment in the U.S. that contains a purified drug substance derived from marijuana -- CBD -- and the first treatment for Dravet syndrome. In September 2018 the FDA rescheduled cannabidiol from a C-I controlled substance to a C-V controlled substance, meaning it has a proven medical use but a low risk of abuse. This change allows Epidiolex to be marketed in the U.S.
Male hemp plants flower much faster than females and do not produce nearly as much fiber. In stark contrast to marijuana fields, most female hemp fields include sporadically placed males. The male hemp plants release pollen for the female hemp plant to produce seeds that will either be used for future crops or sold as food. In marijuana fields, males are typically eliminated to ensure the maximum production of sensimilla flowers.
In 2019, the European Commission announced that CBD and other cannabinoids would be classified as "novel foods",[85] meaning that CBD products would require authorization under the EU Novel Food Regulation stating: because "this product was not used as a food or food ingredient before 15 May 1997, before it may be placed on the market in the EU as a food or food ingredient, a safety assessment under the Novel Food Regulation is required."[86] The recommendation – applying to CBD extracts, synthesized CBD, and all CBD products, including CBD oil – was scheduled for a final ruling by the European Commission in March 2019.[85] If approved, manufacturers of CBD products would be required to conduct safety tests and prove safe consumption, indicating that CBD products would not be eligible for legal commerce until at least 2021.[85]
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.

His third question is whether cannabis serves as a gateway drug. There are two possibilities. The first is that marijuana activates certain behavioral and neurological pathways that ease the onset of more serious addictions. The second possibility is that marijuana offers a safer alternative to other drugs: that if you start smoking pot to deal with chronic pain you never graduate to opioids.


The glutamatergic system is integral to development and maintenance of neuropathic pain, and is responsible for generating secondary and tertiary hyperalgesia in migraine and fibromyalgia via NMDA mechanisms (Nicolodi et al 1998). Thus, it is important to note that cannabinoids presynaptically inhibit glutamate release (Shen et al 1996), THC produces 30%–40% reduction in NMDA responses, and THC is a neuroprotective antioxidant (Hampson et al 1998). Additionally, cannabinoids reduce hyperalgesia via inhibition of calcitonin gene-related peptide (Richardson et al 1998a). As for Substance P mechanisms, cannabinoids block capsaicin-induced hyperalgesia (Li et al 1999), and THC will do so at sub-psychoactive doses in experimental animals (Ko and Woods 1999). Among the noteworthy interactions with opiates and the endorphin/enkephalin system, THC has been shown to stimulate beta-endorphin production (Manzanares et al 1998), may allow opiate sparing in clinical application (Cichewicz et al 1999), prevents development of tolerance to and withdrawal from opiates (Cichewicz and Welch 2003), and rekindles opiate analgesia after a prior dosage has worn off (Cichewicz and McCarthy 2003). These are all promising attributes for an adjunctive agent in treatment of clinical chronic pain states.
Understanding CBD’s analgesic, or pain-relieving, interactions with the ECS can shed light on CBD’s other interactions and effects. Importantly, the ECS participates in our bodies’ pain processing, but when CBD is introduced to our ECS, it stops the body from absorbing a pain-regulating compound known as anandamide — one of our body’s’ own natural cannabinoid molecules. Inhibiting the absorption of this compound shunts excess quantities into the bloodstream that in turn reduces pain. One study has revealed that CBD targets alpha-3 (α3) glycine receptors to suppress chronic pain and inflammation associated with dysfunctional glycine receptors, which are an important target for pain processing in the spine. In both humans and animal models, CBD has been shown to have a variety of anti-inflammatory properties.
The 2018 Farm Bill will radically overhaul America’s relation to hemp and could unleash a hemp renaissance in the coming years that will close the gap between the U.S. and China. As a Schedule 1 substance alongside marijuana, hemp farmers and entrepreneurs in the U.S. have faced many barriers to doing business. Interstate commerce for hemp products was almost non-existent and financing was difficult to come by. But all that is set to change.

What exactly is cannabidiol (CBD) and more importantly, what does it do? Those questions and more are at the heart of this comprehensive guide to one of the most fascinating and important compounds of the cannabis plant. Cannabis plants are chemical powerhouses that produce more than 400 different compounds. Not all of those compounds are unique to marijuana, of course, and appear in many other species of plants. That’s why marijuana can smell like pine trees or taste like fresh lemons. But of those 400 compounds, more than 60 of them are totally specific to the plant genus Cannabis. Scientists call these special compounds “cannabinoids.” However, not all cannabinoids are created equal. One of them, cannabidiol, or CBD, holds the key to the wide variety of medicinal and therapeutic effects marijuana offers.
In the meantime, some physicians are forging ahead — and cashing in. Joe Cohen is a doctor at Holos Health, a medical marijuana clinic in Boulder. I asked him what CBD is good for, and he read me a long list of conditions: pain, inflammation, nausea, vomiting, intestinal cramping, anxiety, psychosis, muscle spasms, hyperactive immune systems, nervous system degeneration, elevated blood sugar and more. He also claimed that CBD has anti-cancer properties and can regenerate brain cells and reduce the brain’s levels of amyloid beta — a kind of protein that’s been linked to Alzheimer’s disease. I asked for references, noting that most of these weren’t listed in the Academies report or a similar review published in the Journal of the American Medical Association. “I think you just have to Google search it,” he said. It’s true that a preliminary study found hints that cannabinoids might reduce beta amyloid proteins in human brain cells, but the study was done in cells grown in a lab, not in people. As for cancer, the FDA sent warning letters last year to four companies that were selling products that claimed to “prevent, diagnose, treat or cure” cancer.

Although the environmental and biodiversity benefits of growing hemp have been greatly exaggerated in the popular press, C. sativa is nevertheless exceptionally suitable for organic agriculture, and is remarkably less “ecotoxic” in comparison to most other crops (Montford and Small 1999b). Figure 50 presents a comparison of the ecological friendliness of Cannabis crops (fiber, oilseed, and narcotics) and 21 of the world’s major crops, based on 26 criteria used by Montford and Small (1999a) to compare the ecological friendliness of crops.
While the other CBD oil stores have high-quality products, our choice simply came down to variety, potency and price. Whichever you choose to go for, though, know that all of the companies above have an outstanding store and offer a wide range of effective products, from CBD oils to Terps and even CBD creams. Plus, most have a 100% money back guarantee policy, which is quite nice!
“Essentially CBD is no different whether extracted from industrial hemp or from marijuana,” Lee explained. “What’s different is what else is in there. When you extract from industrial hemp, you’re not getting a lot of cannabinoids. You’re not getting much CBD. You’re getting very, very little THC. Because it’s a low-resin plant, you don’t have a lot of cannabinoids that are contained in the resin.”

Cannabidiol can be taken into the body in multiple ways, including by inhalation of cannabis smoke or vapor, as an aerosol spray into the cheek, and by mouth. It may be supplied as CBD oil containing only CBD as the active ingredient (no added tetrahydrocannabinol [THC] or terpenes), a full-plant CBD-dominant hemp extract oil, capsules, dried cannabis, or as a prescription liquid solution.[2] CBD does not have the same psychoactivity as THC,[9][10] and may affect the actions of THC.[7][8][9][11] Although in vitro studies indicate CBD may interact with different biological targets, including cannabinoid receptors and other neurotransmitter receptors,[9][12]as of 2018 the mechanism of action for its biological effects has not been determined.[8][9]
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.
Not until the end of the 20th century was the specific mechanism of action of THC at the neuronal level studied.[citation needed] Researchers have subsequently confirmed that THC exerts its most prominent effects via its actions on two types of cannabinoid receptors, the CB1 receptor and the CB2 receptor, both of which are G protein-coupled receptors.[142] The CB1 receptor is found primarily in the brain as well as in some peripheral tissues, and the CB2 receptor is found primarily in peripheral tissues, but is also expressed in neuroglial cells.[143] THC appears to alter mood and cognition through its agonist actions on the CB1 receptors, which inhibit a secondary messenger system (adenylate cyclase) in a dose-dependent manner. These actions can be blocked by the selective CB1 receptor antagonist rimonabant (SR141716), which has been shown in clinical trials to be an effective treatment for smoking cessation, weight loss, and as a means of controlling or reducing metabolic syndrome risk factors.[144] However, due to the dysphoric effect of CB1 receptor antagonists, this drug is often discontinued due to these side effects.[145]
Cannabis use is associated with increased recruitment of task-related areas, such as the dorsolateral prefrontal cortex, which is thought to reflect compensatory activity due to reduced processing efficiency.[114][113][116] Cannabis use is also associated with downregulation of CB1 receptors. The magnitude of down regulation is associated with cumulative cannabis exposure, and is reversed after one month of abstinence.[117][118][119] There is limited evidence that chronic cannabis use can reduce levels of glutamate metabolites in the human brain.[120]
California’s legalization spurred Dr. Geoffrey Guy and Dr. Brian Whittle to found GW Pharmaceuticals, a company that would utilize clinical trials to unpack various cannabinoid formulations as potential therapies with the overriding focus of developing what would later be known as Sativex (Nabiximols). This oral mucosal spray was made up of CBD and THC in a 1:1 ratio and successfully combated neuropathic pain, spasticity, overactive bladder, and symptoms of multiple sclerosis.

The non-intoxicant CBN (cannabinol) is a frequent degradation or oxidation product. The non-intoxicant cannabichromene (CBC) is typically found in trace amounts in intoxicant strains. The non-intoxicant cannabigerol (CBG) is considered to be a precursor of the other cannbinoids (see Fig. 10).

My husband has RSD and we are considering CBD oil -= I would ask at Hempmed because the spray won't have enough in it. Our dgt';s friend has ovarian cancer and it is shrinking her tumors but the spray would never have been enough. I would get CBD oil and check with Hempmeds to see what they suggest. It isn't cheap but it does work. LOW dose Naltrexone about 4.5 mg is very helpful for RSD and is usually used for getting people off of drugs but is working on turning off the glial cells that surround the nerve that is causing the nerve to scream in pain. We are also using PeaPure that is out of the Netherlands and we are seeing a response, even though small. His other leg touched the painful leg without causing more severe pain. That is progress. We also are using Poison Ivy Cream through Meadowlake Farms that has helped the burning surface pain. Change your diet and get rid of Gluten and Sugar, anything that causes inflammation. This is to allow your own body to work. Absolutely do not use any pain killers as it will turn up your pain. all the Hydrocodone, etc causes neural inflammation and so it will keep cascading higher your pain. Hope this is helpful. Mary

Cannabis plants produce a unique family of terpeno-phenolic compounds called cannabinoids, some of which produce the "high" which may be experienced from consuming marijuana. There are 483 identifiable chemical constituents known to exist in the cannabis plant,[49] and at least 85 different cannabinoids have been isolated from the plant.[50] The two cannabinoids usually produced in greatest abundance are cannabidiol (CBD) and/or Δ9-tetrahydrocannabinol (THC), but only THC is psychoactive.[51] Since the early 1970s, Cannabis plants have been categorized by their chemical phenotype or "chemotype", based on the overall amount of THC produced, and on the ratio of THC to CBD.[52] Although overall cannabinoid production is influenced by environmental factors, the THC/CBD ratio is genetically determined and remains fixed throughout the life of a plant.[37] Non-drug plants produce relatively low levels of THC and high levels of CBD, while drug plants produce high levels of THC and low levels of CBD. When plants of these two chemotypes cross-pollinate, the plants in the first filial (F1) generation have an intermediate chemotype and produce intermedite amounts of CBD and THC. Female plants of this chemotype may produce enough THC to be utilized for drug production.[52][53]

"Results of the hemp products tested indicate the amount of THC present in commercially available products is significantly less in products available today than those reported in the past (15-22). As a result, the probability that these products will produce urine THC metabolite levels greater than the DoD and HHS confirmation cutoff of 15 ng/mL is significantly reduced and should not be considered as a realistic cause for a positive urine analysis result."
The etymology is uncertain but there appears to be no common Proto-Indo-European source for the various forms of the word; the Greek term kánnabis is the oldest attested form, which may have been borrowed from an earlier Scythian or Thracian word.[9][10] Then it appears to have been borrowed into Latin, and separately into Slavic and from there into Baltic, Finnish, and Germanic languages.[11] Following Grimm's law, the "k" would have changed to "h" with the first Germanic sound shift,[9][12] after which it may have been adapted into the Old English form, hænep. However, this theory assumes that hemp was not widely spread among different societies until after it was already being used as a psychoactive drug, which Adams and Mallory (1997) believe to be unlikely based on archaeological evidence.[9] Barber (1991) however, argued that the spread of the name "kannabis" was due to its historically more recent drug use, starting from the south, around Iran, whereas non-THC varieties of hemp are older and prehistoric.[11] Another possible source of origin is Assyrian qunnabu, which was the name for a source of oil, fiber, and medicine in the 1st millennium BC.[11]

Just as there was a shift from viewing disease as a state to thinking of it as a process, the same shift happened in definitions of health. Again, the WHO played a leading role when it fostered the development of the health promotion movement in the 1980s. This brought in a new conception of health, not as a state, but in dynamic terms of resiliency, in other words, as "a resource for living". 1984 WHO revised the definition of health defined it as "the extent to which an individual or group is able to realize aspirations and satisfy needs and to change or cope with the environment. Health is a resource for everyday life, not the objective of living; it is a positive concept, emphasizing social and personal resources, as well as physical capacities".[10] Thus, health referred to the ability to maintain homeostasis and recover from insults. Mental, intellectual, emotional and social health referred to a person's ability to handle stress, to acquire skills, to maintain relationships, all of which form resources for resiliency and independent living.[9] This opens up many possibilities for health to be taught, strengthened and learned.
The Duquenois–Levine test is commonly used as a screening test in the field, but it cannot definitively confirm the presence of cannabis, as a large range of substances have been shown to give false positives.[152] Despite this, it is common in the United States for prosecutors to seek plea bargains on the basis of positive D–L tests, claiming them to be conclusive, or even to seek conviction without the use of gas chromatography confirmation, which can only be done in the lab.[153] In 2011, researchers at John Jay College of Criminal Justice reported that dietary zinc supplements can mask the presence of THC and other drugs in urine.[154] However, a 2013 study conducted by researchers at the University of Utah School of Medicine refute the possibility of self-administered zinc producing false-negative urine drug tests.[155]
Going forward, another emerging trend among recreational users are wellness lifestyles built around cannabis. This is certainly part of the influence of California’s new recreational marijuana market, which went online January 1, 2018. California is already an epicenter for health and wellness lifestyles and fads. Expect to see more of the same now that cannabis is completely legal.
When suffering from chronic pain, it can be difficult to find lasting and effective pain relief. Taking CBD oil for pain can be the perfect solution, especially when you consider how bleak the other options can appear. You can suffer through medications that do not provide enough relief, or, you can take a variety of prescribed pharmaceuticals that can carry significant side effects that can further diminish your health and quality of life.
"Hemp fibers are used in fabrics and textiles, yarns and spun fibers, paper, carpeting, home furnishings, construction and insulation materials, auto parts, and composites. Hurds are used in animal bedding, material inputs, papermaking, and oil absorbents. Hemp seed and oilcake are used in a range of foods and beverages (e.g., salad and cooking oil and hemp dairy alternatives) and can be an alternative food and feed protein source.8 Oil from the crushed hemp seed is used in soap, shampoo, lotions, bath gels, and cosmetics.9 Hemp is also being used in nutritional supplements and in medicinal and therapeutic products, including pharmaceuticals. It is also used in a range of composite products. Hempcrete (a mixture of hemp hurds and lime products) is being used as a building material. Hemp is also used as a lightweight insulating material and in hemp plastics and related composites for use as a fiberglass alternative by the automotive and aviation sectors.10 Hemp is also promoted as a potential biodiesel feedstock11 and cover crop."

Hi Colleen, it's almost a year later and I'm wondering how you're doing. I'm experiencing a recurrence of Stage 3 ovarian, originally diagnosed in 2011. I've decided to get some chemo, not sold on another 6 cycles though. As a new MMJ patient, I'm still going to go through with Rick Simpson Oil (THC+CBD,) and I just joined a program with my local dispensary to get CBD capsules for $2 each when I order them at least 30 at a time. I hope you're doing well!! I'm off to do more research on dosing. **NOTE: If you have ANY experience with CBD treatment of ovarian cancer, PLEASE respond. Thank you!!
Finding the perfect CBD Oil daily dosage is now easier than ever, thanks to CBD Daily Doses, from Green Roads. Cannabinoids like CBD interact with our body’s endocannabinoid system to produce their effects. This network of chemicals signalers and receptors is responsible for maintaining homeostasis of both body and mind. While it’s important to balance your endocannabinoid system with CBD, it’s just as important to balance your daily schedule, and CBD Daily Doses make it easy and simple to do just that.
But even though it's infiltrating pretty much every corner of the wellness world (hi, vegan CBD brownies!) many people still find CBD a little confusing—especially when it comes to figuring out the right way to use it and how to make sure the stuff you're buying is, you know, actually legit. Below, we asked experts to answer the most pressing questions about CBD.
“The brain has these receptors that respond to endocannabinoids, which are neurotransmitters that are naturally produced in the body and brain,” says Jerald Simmons, a neurologist at Houston’s Comprehensive Sleep Medicine Associates. “Some of the cannabinoids in the marijuana plant are very similar to the endocannabinoids in the brain, and they act on the same receptors.”
In 2017, China imported more than $24 billion in agriculture products from the U.S. The world’s top wheat consumer, China and purchased 1.6 million tons of U.S. wheat worth $391 million. At the same time, China bought $14 billion in soybeans for personal and animal consumption from the U.S. last year--more than any other agricultural commodity, and the country's corn imports from the U.S. were worth $160 million.
“The plan? Whip the public into a frenzy over ill effects of marijuana, the psychoactive leaves and flowers of the hemp plant; the reputation of the fibers and seeds used by industry would be posing little threat to society emerged as the ‘assassin of youth.’ The strategy worked. In 1937, with virtually no warning, Congress announced a prohibitive tax on hemp, effectively ending the production and sale of the plant in the United States.
Plant, (kingdom Plantae), any multicellular eukaryotic life-form characterized by (1) photosynthetic nutrition (a characteristic possessed by all plants except some parasitic plants and underground orchids), in which chemical energy is produced from water, minerals, and carbon dioxide with the aid of pigments and the radiant energy of the Sun, (2)…
Among members of the public-health community, it is impossible to spend five minutes on the e-cigarette question without getting into an argument. And this is nicotine they are arguing about, a drug that has been exhaustively studied by generations of scientists. We don’t worry that e-cigarettes increase the number of fatal car accidents, diminish motivation and cognition, or impair academic achievement. The drugs through the gateway that we worry about with e-cigarettes are Marlboros, not opioids. There are no enormous scientific question marks over nicotine’s dosing and bio-availability. Yet we still proceed cautiously and carefully with nicotine, because it is a powerful drug, and when powerful drugs are consumed by lots of people in new and untested ways we have an obligation to try to figure out what will happen.

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.[26] 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.[29] Soon thereafter, Schaffner disputed Hirata's interpretation,[30] 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.[27]

“We have intellectual property that we’ve developed around how to manage hemp, and that we thought was prudent, because I think hemp is going to happen in the U.S. and when it does, I know that’s not the time to start,” said Canopy Chief Executive Bruce Linton in November’s earnings conference call. “You should have already been started up and ramped up, and get ready to revenue up. We think we are.”
When it comes to cannabis, the best-case scenario is that we will muddle through, learning more about its true effects as we go along and adapting as needed—the way, say, the once extraordinarily lethal innovation of the automobile has been gradually tamed in the course of its history. For those curious about the worst-case scenario, Alex Berenson has written a short manifesto, “Tell Your Children: The Truth About Marijuana, Mental Illness, and Violence.”
Textile expert Elizabeth Wayland Barber summarizes the historical evidence that Cannabis sativa, "grew and was known in the Neolithic period all across the northern latitudes, from Europe (Germany, Switzerland, Austria, Romania, Ukraine) to East Asia (Tibet and China)," but, "textile use of Cannabis sativa does not surface for certain in the West until relatively late, namely the Iron Age."[114] "I strongly suspect, however, that what catapulted hemp to sudden fame and fortune as a cultigen and caused it to spread rapidly westwards in the first millennium B.C. was the spread of the habit of pot-smoking from somewhere in south-central Asia, where the drug-bearing variety of the plant originally occurred. The linguistic evidence strongly supports this theory, both as to time and direction of spread and as to cause."[115]
Luke Zigovits, chief executive of Wisconsin-based Hemp Science, said, “We can finally relax. Because now we can source seed, now we can sell our product across state lines. Prohibition is over. It broadens horizons, allowing universities to do research, for example.” Beyond moving the industry into legitimacy, Zigovits said there are opportunities for tobacco farmers in Wisconsin and elsewhere to start growing industrial hemp crops as well.
Cognitive effects of cannabis have been reviewed (Russo et al 2002; Fride and Russo 2006), but less study has occurred in therapeutic contexts. Effects of chronic heavy recreational cannabis usage on memory abate without sequelae after a few weeks of abstinence (Pope et al 2001). Studies of components of the Halstead-Reitan battery with Sativex in neuropathic pain with allodynia have revealed no changes vs placebo (Nurmikko et al 2007), and in central neuropathic pain in MS (Rog et al 2005), 4 of 5 tests showed no significant differences. While the Selective Reminding Test did not change significantly on Sativex, placebo patients displayed unexpected improvement.
The meaning of health has evolved over time. In keeping with the biomedical perspective, early definitions of health focused on the theme of the body's ability to function; health was seen as a state of normal function that could be disrupted from time to time by disease. An example of such a definition of health is: "a state characterized by anatomic, physiologic, and psychological integrity; ability to perform personally valued family, work, and community roles; ability to deal with physical, biological, psychological, and social stress".[7] Then in 1948, in a radical departure from previous definitions, the World Health Organization (WHO) proposed a definition that aimed higher: linking health to well-being, in terms of "physical, mental, and social well-being, and not merely the absence of disease and infirmity".[8] Although this definition was welcomed by some as being innovative, it was also criticized as being vague, excessively broad and was not construed as measurable. For a long time, it was set aside as an impractical ideal and most discussions of health returned to the practicality of the biomedical model.[9]
Common adverse events (AE) of Sativex acutely in RCTs have included complaints of bad taste, oral stinging, dry mouth, dizziness, nausea or fatigue, but do not generally necessitate discontinuation, and prove less common over time. While there have been no head-to-head comparative RCTs of Sativex with other cannabinoid agents, certain contrasts can be drawn. Sativex (Rog et al 2005) and Marinol (Svendsen et al 2004) have both been examined in treatment of central neuropathic pain in MS, with comparable results (Table 1). However, adverse events were comparable or greater with Marinol than with Sativex employing THC dosages some 2.5 times higher due to the presence of accompanying CBD (Russo 2006b; Russo and Guy 2006).
CatryNA49; Cannabis, like Opium poppies, and the substances derived from these plants, were also made illegal as a means of preventing white females, from being seduced, and or raped by male members of minority races; seriously ! In the early 70s Nixon administration officials oversaw the expansion of drug laws, as a means of legally repressing the two groups of Americans, that administration deemed to be their biggest foes; those groups being, African Americans, and the antiwar left. We know the drug war, just like the earlier less repressive drug laws, was initiated as a means of legal political, and racial repression because of the fact that a Nixon adm. official is on film, admitting as much. You can Google that film if you like. Now despite the truth about the drug war being admitted on film, for anyone in the world who has internet access can see, the drug war continues to be waged by politicians; the same politicians by the way, that tens of millions of Americans continue to vote for. I should add, that in the last presidential election, the candidate who promised to refuel the drug war, was the candidate who won that election. Of course what else could you expect, being that we live in the land of the free and the home of the brave ?!
Berenson used to be an investigative reporter for the Times, where he covered, among other things, health care and the pharmaceutical industry. Then he left the paper to write a popular series of thrillers. At the time of his conversation with his wife, he had the typical layman’s view of cannabis, which is that it is largely benign. His wife’s remark alarmed him, and he set out to educate himself. Berenson is constrained by the same problem the National Academy of Medicine faced—that, when it comes to marijuana, we really don’t know very much. But he has a reporter’s tenacity, a novelist’s imagination, and an outsider’s knack for asking intemperate questions. The result is disturbing.
Recent controversies have arisen in relation to non-steroidal anti-inflammatory drugs (NSAID), with concerns that COX-1 agents may provoke gastrointestinal ulceration and bleeding, and COX-2 drugs may increase incidents of myocardial infarction and cerebrovascular accidents (Fitzgerald 2004; Topol 2004). In contrast, neither THC nor CBD produce significant COX inhibition at normal dosage levels (Stott et al 2005a).
In 1988, the first cannabinoid receptor was identified (CB1) (Howlett et al 1988) and in 1993, a second was described (CB2) (Munro et al 1993). Both are 7-domain G-protein coupled receptors affecting cyclic-AMP, but CB1 is more pervasive throughout the body, with particular predilection to nociceptive areas of the central nervous system and spinal cord (Herkenham et al 1990; Hohmann et al 1999), as well as the peripheral nervous system (Fox et al 2001; Dogrul et al 2003) wherein synergy of activity between peripheral and central cannabinoid receptor function has been demonstrated (Dogrul et al 2003). CB2, while commonly reported as confined to lymphoid and immune tissues, is also proving to be an important mediator for suppressing both pain and inflammatory processes (Mackie 2006). Following the description of cannabinoid receptors, endogenous ligands for these were discovered: anandamide (arachidonylethanolamide, AEA) in 1992 in porcine brain (Devane et al 1992), and 2-arachidonylglycerol (2-AG) in 1995 in canine gut tissue (Mechoulam et al 1995) (Figure 1). These endocannabinoids both act as retrograde messengers on G-protein coupled receptors, are synthesized on demand, and are especially active on glutamatergic and GABA-ergic synapses. Together, the cannabinoid receptors, their endogenous ligands (“endocannabinoids”) and metabolizing enzymes comprise the endocannabinoid system (ECS) (Di Marzo et al 1998), whose functions have been prosaically termed to be “relax, eat, sleep, forget and protect” (p. 528). The endocannabinoid system parallels and interacts at many points with the other major endogenous pain control systems: endorphin/enkephalin, vanilloid/transient receptor potential (TRPV), and inflammatory. Interestingly, our first knowledge of each pain system has derived from investigation of natural origin analgesic plants, respectively: cannabis (Cannabis sativa, C. indica) (THC, CBD and others), opium poppy (Papaver somniferun) (morphine, codeine), chile peppers (eg, Capsicum annuum, C. frutescens, C. chinense) (capsaicin) and willow bark (Salix spp.) (salicylic acid, leading to acetylsalicylic acid, or aspirin). Interestingly, THC along with AEA and 2-AG, are all partial agonists at the CB1 receptor. Notably, no endocannabinoid has ever been administered to humans, possibly due to issues of patentability and lack of commercial feasibility (Raphael Mechoulam, pers comm 2007). For an excellent comprehensive review of the endocannabinoid system, see Pacher et al (2006), while Walker and Huang have provided a key review of antinociceptive effects of cannabinoids in models of acute and persistent pain (Walker and Huang 2002).
The tricky part is that there's some evidence suggesting CBD works best for pain when combined with a little THC, says Dr. Danesh. "Depending on what type of pain you have, you might be able to do just CBD, but sometimes you need CBD and THC." This makes accessing a product that will actually help you more difficult due to different regulations in each state. In New York, where Dr. Danesh practices, for example, CBD is available over the counter. But as soon as you add THC, you need a prescription.
Medical cannabis, or medical marijuana, can refer to the use of cannabis and its cannabinoids to treat disease or improve symptoms; however, there is no single agreed-upon definition.[39][40] The rigorous scientific study of cannabis as a medicine has been hampered by production restrictions and other federal regulations.[41] There is limited evidence suggesting cannabis can be used to reduce nausea and vomiting during chemotherapy, to improve appetite in people with HIV/AIDS, and to treat chronic pain and muscle spasms.[42][43][44] Its use for other medical applications is insufficient for conclusions about safety or efficacy.
The etymology is uncertain but there appears to be no common Proto-Indo-European source for the various forms of the word; the Greek term kánnabis is the oldest attested form, which may have been borrowed from an earlier Scythian or Thracian word.[9][10] Then it appears to have been borrowed into Latin, and separately into Slavic and from there into Baltic, Finnish, and Germanic languages.[11] Following Grimm's law, the "k" would have changed to "h" with the first Germanic sound shift,[9][12] after which it may have been adapted into the Old English form, hænep.

Researchers in New Zealand have studied whether cannabis can be used to treat severe motor and vocal tics in those suffering from Tourette syndrome. The study concluded that subjects who took a controlled THC-CBD medicated spray showed marked improvement in the frequency and severity of motor and vocal tics post-treatment. Although the study is only a small clinical trial, it is one of the first to specifically analyze the effects of cannabis on Tourette syndrome.
"The quality of an oil or fat is most importantly determined by its fatty acid composition. Hemp is of high nutritional quality because it contains high amounts of unsaturated fatty acids, mostly oleic acid (C18:1, 10%–16%), linoleic acid (C18:2, 50%–60%), alpha-linolenic acid (C18:3, 20%–25%), and gammalinolenic acid (C18:3, 2%–5%) (Fig. 37). Linoleic acid and alpha-linolenic acid are the only two fatty acids that must be ingested and are considered essential to human health (Callaway 1998). In contrast to shorter-chain and more saturated fatty acids, these essential fatty acids do not serve as energy sources, but as raw materials for cell structure and as precursors for biosynthesis for many of the body’s regulatory biochemicals."

It makes no sense to me that something that helps with anxiety has an irritability side effect – as a lot of my anxiety is co-mingled naturally with irritability. Further, I have noticed none of these side effects, given that if you become fatigued or sleepy, you adjust dose the next day. So I don’t call that a side effect – rather – an effect of taking too much.


Technically speaking, its THC—the cannabinoid that gets you high—which is illicit. When you take a drug test, the aim is to detect THC in your body, not “cannabis.” If you possessed weed without any THC in it, technically you wouldn’t be in violation of the law. Because “weed” without THC has a different name: hemp. And the rules governing hemp are quite different from the restrictions placed on cannabis.
In the United Kingdom, cultivation licences are issued by the Home Office under the Misuse of Drugs Act 1971. When grown for nondrug purposes, hemp is referred to as industrial hemp, and a common product is fibre for use in a wide variety of products, as well as the seed for nutritional aspects and for the oil. Feral hemp or ditch weed is usually a naturalized fibre or oilseed strain of Cannabis that has escaped from cultivation and is self-seeding.[91]

Probably indigenous to temperate Asia, C. sativa is the most widely cited example of a “camp follower.” It was pre-adapted to thrive in the manured soils around man’s early settlements, which quickly led to its domestication (Schultes 1970). Hemp was harvested by the Chinese 8500 years ago (Schultes and Hofmann 1980). For most of its history, C. sativa was most valued as a fiber source, considerably less so as an intoxicant, and only to a limited extent as an oilseed crop. Hemp is one of the oldest sources of textile fiber, with extant remains of hempen cloth trailing back 6 millennia. Hemp grown for fiber was introduced to western Asia and Egypt, and subsequently to Europe somewhere between 1000 and 2000 BCE. Cultivation in Europe became widespread after 500 ce. The crop was first brought to South America in 1545, in Chile, and to North America in Port Royal, Acadia in 1606. The hemp industry flourished in Kentucky, Missouri, and Illinois between 1840 and 1860 because of the strong demand for sailcloth and cordage (Ehrensing 1998). From the end of the Civil War until 1912, virtually all hemp in the US was produced in Kentucky. During World War I, some hemp cultivation occurred in several states, including Kentucky, Wisconsin, California, North Dakota, South Dakota, Minnesota, Indiana, Illinois, Ohio, Michigan, Kansas, and Iowa (Ehrensing 1998). The second world war led to a brief revival of hemp cultivation in the Midwest, as well as in Canada, because the war cut off supplies of fiber (substantial renewed cultivation also occurred in Germany for the same reason). Until the beginning of the 19th century, hemp was the leading cordage fiber. Until the middle of the 19th century, hemp rivaled flax as the chief textile fiber of vegetable origin, and indeed was described as “the king of fiber-bearing plants,—the standard by which all other fibers are measured” (Boyce 1900). Nevertheless, the Marihuana Tax Act applied in 1938 essentially ended hemp production in the United States, although a small hemp fiber industry continued in Wisconsin until 1958. Similarly in 1938 the cultivation of Cannabis became illegal in Canada under the Opium and Narcotics Act.
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.

From the 1950s to the 1980s, the Soviet Union was the world's largest producer of hemp (3,000 square kilometres (1,200 sq mi) in 1970). The main production areas were in Ukraine,[87] the Kursk and Orel regions of Russia, and near the Polish border. Since its inception in 1931, the Hemp Breeding Department at the Institute of Bast Crops in Hlukhiv (Glukhov), Ukraine, has been one of the world's largest centers for developing new hemp varieties, focusing on improving fiber quality, per-hectare yields, and low THC content.[88][89]

Hemp is thus profitable and sustainable, two words which have eluded many U.S. farmers as of late. Hemp cultivation could provide much-needed relief as farmers struggle to find markets for millions of bushels of crops during the trade wars. Now, instead of importing an estimated $100 million of hemp products every year, that money will go to American farmers and entrepreneurs.
One of the earliest success stories involves a young girl named Charlotte who was given an ingestible oil derived from Charlotte’s Web, a CBD strain that was specifically developed to provide her with all the benefits of the drug without the high. In less than two years, Charlotte went from a monthly seizure count of 1,200 to about three. Other success stories followed and more parents have begun to speak out, particularly parents who are desperate for access to this life-saving treatment.

Indoor marijuana grows provide the most control over growing conditions. With a simple setup including a tent, proper lighting, and an air circulation system, home marijuana growers can produce consistent yields. Both soil and hydro systems can be utilized for indoor marijuana grows. Soil setups are generally cheaper and more forgiving, but hydro systems tend to be more common.


Scientists in Europe and North America concluded that hemp seed is an excellent source of nutrition. Numerous anecdotal incidences cited improvements in a wide range of acute and chronic conditions such as rapid healing of skin lesions and relief from flu, inflammation, and allergies. The benefits were attributed to the presence of rich source of the EFAs linoleic and alpha-linolenic acid, and their respective biologic metabolites, GLA and stearidonic acid.9
"Approximately 30 countries in Europe, Asia, and North and South America currently permit farmers to grow hemp. Some of these countries never outlawed production, while some countries banned production for certain periods in the past. China is among the largest producing and exporting countries of hemp textiles and related products, as well as a major supplier of these products to the United States. The European Union (EU) has an active hemp market, with production in most member nations. Production is centered in France, the United Kingdom, Romania, and Hungary.30
Although I’m no physician, and am not qualified to recommend any drugs for any specific medical purposes, and you should consult your doctor when considering the consumption of anything that may be medicinal: If you’re looking to experiment with CBD products, you might consider looking for CBD products that are “whole plant” extract based from very high CBD cultivars. If you’re in a State that has a legal Cannabis system, you may also find more therapeutic benefits from non-hemp derived CBD products.
The high lipid-solubility of cannabinoids results in their persisting in the body for long periods of time.[140] 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).[140] 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.[141]
I have neuropathic pain. I’ve tried 3 brands now, this last one being less expensive. I “think” it’s helping a little bit…. maybe it’s wishful thinking. I never really knew how much to take. There is so much confusion on dosing, so I just take a dropper full now. Maybe that’s too much, maybe not. Should I take it twice a day, or once? I find it very hard to compare brand to brand. Thank you for your detailed, informative article. If anyone would care to share how much oil they take daily, I would appreciate it. I’m just trying to get a rough idea of what’s normal, an average. thanks.

"Since the mid-1990s, there has been a resurgence of interest in the United States in producing industrial hemp. Farmers in regions of the country that are highly dependent upon a single crop, such as tobacco or wheat, have shown interest in hemp’s potential as a high-value alternative crop, although the economic studies conducted so far paint a mixed profitability picture.

Cannabis was criminalized in various countries beginning in the 19th century. The British colonies of Mauritius banned cannabis in 1840 over concerns on its effect on Indian indentured workers;[206] the same occurred in British Singapore in 1870.[207] In the United States, the first restrictions on sale of cannabis came in 1906 (in District of Columbia).[208] It was outlawed in Jamaica (then a British colony) in 1913, in South Africa in 1922, and in the United Kingdom and New Zealand in the 1920s.[209] Canada criminalized cannabis in The Opium and Narcotic Drug Act, 1923,[210] before any reports of the use of the drug in Canada, but eventually legalized its consumption for recreational and medicinal purposes in 2018.[38]


We went back and forth like that for several rounds, yelling at each other in 30-degree weather in front of an RV wrapped in marijuana-leaf graphics and blasting Bob Marley music. Finally, he stopped trying to enlighten me and shuffled off to let me buy my lollies in peace. As I tore into my new treats, I realized the whole thing had been a scene from the internet’s dominant cannabidiol discourse come to life: Some money had been spent and some opinions had been said, but no one had gained any information.

At an epidemiological level, a dose–response relationship exists between cannabis use and increased risk of psychosis[127][128][129] and earlier onset of psychosis.[130] Although the epidemiological association is robust, evidence to prove a causal relationship is lacking.[131] But a biological causal pathway is plausible, especially if there is a genetic predisposition to mental illness, in which case cannabis may be a trigger.[132][better source needed]
Several animal studies have led researchers to believe that cannabis could reverse signs of aging in the brain. Aging mice treated with small daily doses of THC showed a reversal in cognitive decline. However, past studies on the effects of cannabis on human memory show less promising results. Still, with few viable treatments for dementia, medical marijuana is receiving increased attention in this area.

But before you do that, know that all hemp CBD oils are not created equal! A recent study published in the Journal of the American Medical Association found nearly 70 percent of hemp CBD oil sold online was mislabeled. During the Penn Medicine study, researchers analyzed 84 products purchased from 31 companies. Around 42 percent of products were under-labeled, meaning the product contained more CBD than labeled. Twenty-six percent of products contained less CBD than indicated on packaging.
A clinical endocannabinoid deficiency has been postulated to be operative in certain treatment-resistant conditions (Russo 2004), and has received recent support in findings that anandamide levels are reduced over controls in migraineurs (Sarchielli et al 2006), that a subset of fibromyalgia patients reported significant decreased pain after THC treatment (Schley et al 2006), and the active role of the ECS in intestinal pain and motility in irritable bowel syndrome (Massa and Monory 2006) wherein anecdotal efficacy of cannabinoid treatments have also been claimed.

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.[150]

"No data are available on imports of hemp seed and oil into the United States, but data do exist on hemp fiber, yarn, and fabrics. Imports of raw hemp fiber have increased dramatically in the last few years, rising from less than 500 pounds in 1994 to over 1.5 million pounds for the first 9 months of 1999. Yarn imports also have risen substantially, peaking at slightly less than 625,000 pounds in 1997. The switch from yarn to raw fiber in the last 2 years probably reflects the development of U.S. spinning capacity. At least two companies are now spinning hemp yarn from imported fibers. Imports of hemp fabric have more than doubled from over 222,000 pounds in 1995 to about 523,000 pounds in 1998.
We all know of Charlotte’s Web; the miracle strain that is packed with a high concentration of CBD. The Charlotte’s Web Cannabis Strain was named after Charlotte Figi, who suffers from Dravet syndrome and was experiencing several seizures daily until the Stanley Brothers came up with this powerful strain. Since then, Charlotte’s web has been morphed into various products, including their famous Charlotte’s Web CBD oil.
Male hemp plants flower much faster than females and do not produce nearly as much fiber. In stark contrast to marijuana fields, most female hemp fields include sporadically placed males. The male hemp plants release pollen for the female hemp plant to produce seeds that will either be used for future crops or sold as food. In marijuana fields, males are typically eliminated to ensure the maximum production of sensimilla flowers.
