I just started taking CBD oil , I am on my 2nd Hip replacement surgery due to device failures looking at a 3rd surgery. Has you can imagine the pain, stress and anxiety levels are off the charts. Especially at an otherwise healthy 54 yr women. So i understand from reading posts its best to take it under the tongue. I am taking 1-2 ml a day. I can tell some difference,is your recommended dosage. I am using for pain , stress and sleep. I appreciate your feedback.
Berenson’s second question derives from the first. The delusions and paranoia that often accompany psychoses can sometimes trigger violent behavior. If cannabis is implicated in a rise in psychoses, should we expect the increased use of marijuana to be accompanied by a rise in violent crime, as Berenson’s wife suggested? Once again, there is no definitive answer, so Berenson has collected bits and pieces of evidence. For example, in a 2013 paper in the Journal of Interpersonal Violence, researchers looked at the results of a survey of more than twelve thousand American high-school students. The authors assumed that alcohol use among students would be a predictor of violent behavior, and that marijuana use would predict the opposite. In fact, those who used only marijuana were three times more likely to be physically aggressive than abstainers were; those who used only alcohol were 2.7 times more likely to be aggressive. Observational studies like these don’t establish causation. But they invite the sort of research that could.
Researchers think that CBD interacts with receptors in your brain and immune system. Receptors are tiny proteins attached to your cells that receive chemical signals from different stimuli and help your cells respond. This creates anti-inflammatory and painkilling effects that help with pain management. This means that CBD oil may benefit people with chronic pain, such as chronic back pain.
“Geotextiles” or “agricultural textiles” include (1) ground-retaining, biodegradable matting designed to prevent soil erosion, especially to stabilize new plantings while they develop root systems along steep highway banks to prevent soil slippage (Fig. 32); and (2) ground-covers designed to reduce weeds in planting beds (in the manner of plastic mulch). At present the main materials used are polymeric (polythene, spun-blown polypropylene) and some glass fiber and natural fibers. Both woven and non-woven fibers can be applied to geotextiles; woven and knitted materials are stronger and the open structure may be advantageous (e.g. in allowing plants to grow through), but non-wovens are cheaper and better at suppressing weeds. Flax and hemp fibers exposed to water and soil have been claimed to disintegrate rapidly over the course of a few months, which would make them unacceptable for products that need to have long-term stability when exposed to water and oil. Coco (coir) fiber has been said to be much more suitable, due to higher lignin content (40%–50%, compared to 2%–5% in bast fibers); these are much cheaper than flax and hemp fibers (Karus et al. 2000). However, this analysis does not do justice to the developing hemp geotextile market. Production of hemp erosion control mats is continuing in both Europe and Canada. Given the reputation for rot resistance of hemp canvas and rope, it seems probable that ground matting is a legitimate use. Moreover, the ability to last outdoors for many years is frequently undesirable in geotextiles. For example, the widespread current use of plastic netting to reinforce grass sod is quite objectionable, the plastic persisting for many years and interfering with lawn care. Related to geotextile applications is the possibility of using hemp fiber as a planting substrate (biodegradable pots and blocks for plants), and as biodegradable twine to replace plastic ties used to attach plants to supporting poles. Still another consideration is the “green ideal” of producing locally for local needs; by this credo, hemp is preferable in temperate regions to the use of tropical fibers, which need to be imported.
I use cbd oil every day. I refuse to go without it. I have no arthritic pain at all anymore. I had a hip replacement 3 years ago. I am in need of the other one to be replaced. I was laying awake crying at night because of my hip pain. After I started using the oil my hip has quit aching. I sometimes forget I even have a problem with it or my arthritis. Had I known about the oil before I had my hip replaced I never would have had the surgery. I am pain free. I use hemp oil. There are 20 mg of cannabiniol in each 1 ml dose.

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.
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
I use this for my anxiety and for my arthritis. The topical works great for my chronic neck pain. The best way to go is to get your own raw, tested material and use it in whatever form you like. It’s quite easy to make your own extract. This has worked better for me, rather than relying on a purchased, untested product – where some seem to work and others are a waste. But even with those that work, of course the cost is ridiculous and not affordable, thanks to all these corporate-pleasing laws in place, not there for the people – don’t delude yourselves.
The authors compared this patient's CT scan with one from a cigarette smoker. The second scan illustrated a strikingly different pattern of emphysema, with smaller panacinar bullae in a uniformly distributed centrilobular pattern. An explanation of the differences in lung findings due to cannabis and cigarettes would take into account a number of variables. Cannabis smoking requires longer inhalation and breath-holding time. Inhaled cannabis through a bong is at a higher temperature. A cannabis joint, which lacks a filter, also has a greater delivery of the drug.
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.
Hemp is a farmer's friend because compared with cotton, corn, and soybeans, it requires little water, isn't picky when it comes to poor soil. It grows tightly spaced, thus crowding out weeds, and boasts a deep, soil-aerating root system. Despite all its advantages, and because growing it is illegal with the exception of limited licenses, the U.S. imports approximately $60 million worth of hemp from overseas countries like China.
The seeds are sown with grain drills or other conventional seeding equipment to a depth of 1.27 to 2.54 cm. Greater seeding depths result in increased weed competition. Nitrogen should not be placed with the seed, but phosphate may be tolerated. The soil should have available 89 to 135 kg/ha of nitrogen, 46 kg/ha phosphorus, 67 kg/ha potassium, and 17 kg/ha sulfur. Organic fertilizers such as manure are one of the best methods of weed control.[58]

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]
Hemp is grown in temperate zones as an annual cultivated from seed and can reach a height of up to 5 metres (16 feet). Crops grow best in sandy loam with good drainage and require average monthly rainfall of at least 65 mm (2.5 inches) throughout the growing season. Crops cultivated for fibre are densely sowed and produce plants averaging 2–3 metres (6–10 feet) tall with almost no branching. Plants grown for oilseed are planted farther apart and are shorter and many-branched. The slender stalks are hollow except at the tip and base. The leaves are compound with palmate shape, and the flowers are small and greenish yellow. Seed-producing flowers form elongate, spikelike clusters growing on the pistillate, or female, plants. Pollen-producing flowers form many-branched clusters on staminate, or male, plants. Maximum yield and quality are obtained by harvesting soon after the plants reach maturity, indicated by the full blossoms and freely shedding pollen of the male plants. Although sometimes pulled up by hand, plants are more often cut off about 2.5 cm (1 inch) above the ground.
While CBD is considered the major non-psychoactive component of cannabis, in studies using varied doses, routes of administration, and combination or whole products with THC, a number of side effects have been reported, including anxiety, changes in appetite and mood, diarrhea, dizziness, drowsiness, dry mouth, low blood pressure, mental confusion, nausea, and vomiting.
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

Hello. I have stage 4 thyroid, secondary lymphoma..And many other health issues.I use 50mg of cbd vapor oil. 5 drops with each use. Total equals 250mg, about hits per dose, three times a day. I'm also on subsys, which is fentanyl. Idk about anyone but myself, but it's helped me with pain, with sleep, and in general my moods. So I dint have anything negative to say. I just hope that with time, proper diet, low dose chemo, and some other herbal usage, that I can shirk some of the cancer eating at my body... Thanks and good luck to you all.

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)… 

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]
Food and beverage products containing CBD were introduced in the United States in 2017.[52] Similar to energy drinks and protein bars which may contain vitamin or herbal additives, food and beverage items can be infused with CBD as an alternative means of ingesting the substance.[53] In the United States, numerous products are marketed as containing CBD, but in reality contain little or none.[54] Some companies marketing CBD-infused food products with claims that are similar to the effects of prescription drugs have received warning letters from the Food and Drug Administration for making unsubstantiated health claims.[55] In February 2019, the New York City Department of Health announced plans to fine restaurants that sell food or drinks containing CBD, beginning in October 2019.[56]
Fig. 8. Scanning electron micrographs of the abaxial surface of a perigonal bract (which envelops the fruit). These bracts are the most intoxicating part of the plant, and may contain 20% THC, dry weight. The resin is synthesized both in stalked and sessile glands. Multicellular secretory glands (of phallic appearance), some broken stalks of these (note cellular appearance), and unicellular cystolith hairs (claw-like structures) are pictured. Fig. 9. 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).

Many monoecious varieties have also been described,[20] in which individual plants bear both male and female flowers.[21] (Although monoecious plants are often referred to as "hermaphrodites", true hermaphrodites – which are less common in Cannabis – bear staminate and pistillate structures together on individual flowers, whereas monoecious plants bear male and female flowers at different locations on the same plant.) Subdioecy (the occurrence of monoecious individuals and dioecious individuals within the same population) is widespread.[22][23][24] Many populations have been described as sexually labile.[25][26][27]

The Drug Enforcement Agency and the Office of National Drug Control Policy of the US raised concerns over tests conducted from 1995 to 1997 that showed that consumption of hempseed products available during that period led to interference with drug-testing programs for marijuana use. Federal US programs utilize a THC metabolite level of 50 parts per billion in urine. Leson (2000) found that this level was not exceeded by consuming hemp products, provided that THC levels are maintained below 5 ppm in hemp oil, and below 2 ppm in hulled seeds. Nevertheless the presence of even minute trace amounts of THC in foods remains a tool that can be used by those wishing to prevent the hemp oilseed industry from developing.
A 2011 study evaluated the effects of two non-psychoactive cannabinoids, cannabidiol (CBD) and cannabichromene (CBC), on pain management. The study concluded that, “CBD and CBC stimulated descending pathways of antinociception and caused analgesia by interacting with several target proteins involved in nociceptive control. These compounds might represent useful therapeutic agents with multiple mechanisms of action.”
I have lower back pain with some arthritis and arthritis in my hands.ive recently tried CBD Oil. It really does work. I have the drops and ointment. They both work. Because of the back pain I never would have been able to go on a hike with my family. We had a lot of fun. And "No Pain", all day. I'm also Type 2 diabetic. Anxious to see what my A1C is next month. I'm a believer.
I am currently doing a research paper on the benefits of hemp, and medicinal marijuana. Lets just say I am “experianced”, and knowledgable when it comes to the advantages. (c’mon, stoners cannot be that ‘spaced out’ if even we see the impact hemp itself could make) I chose this topic to voice not only my opinion on the matter, but the facts in the matter. Thank you for the valuble information on your site! It has helped to improve my paper for sure!!
