Because of its high THC-content, in most parts of the world, including the US, Marijuana is illegal. Seeing the massive economical and medicinal benefits that Marijuana can provide, some countries and states in the US have legalized Marijuana. As the political landscape changes, hopefully more will follow, but as of now, Marijuana is generally illegal.
CBD has also been demonstrated to exert a chemopreventive effect in a mouse model of colon cancer.[21] In this experimental system, azoxymethane increased premalignant and malignant lesions in the mouse colon. Animals treated with azoxymethane and CBD concurrently were protected from developing premalignant and malignant lesions. In in vitro experiments involving colorectal cancer cell lines, the investigators found that CBD protected DNA from oxidative damage, increased endocannabinoid levels, and reduced cell proliferation. In a subsequent study, the investigators found that the antiproliferative effect of CBD was counteracted by selective CB1 but not CB2 receptor antagonists, suggesting an involvement of CB1 receptors.[22]
The vegetable oils have been classified by “iodine value” as drying (120–200), semi-drying (100–120), and non-drying (80–100), which is determined by the degree of saturation of the fatty acids present (Raie et al. 1995). Good coating materials prepared from vegetable oil depend on the nature and number of double bonds present in the fatty acids. Linseed oil, a drying oil, has a very high percentage of linolenic acid. Hempseed oil has been classified as a semi-drying oil, like soybean oil, and is therefore more suited to edible than industrial oil purposes. Nevertheless hemp oil has found applications in the past in paints, varnishes, sealants, lubricants for machinery, and printing inks. However, such industrial end uses are not presently feasible as the oil is considered too expensive (de Guzman 2001). Larger production volumes and lower prices may be possible, in which case hemp oil may find industrial uses similar to those of linseed (flax), soybean, and sunflower oils, which are presently used in paints, inks, solvents, binders, and in polymer plastics. Hemp shows a remarkable range of variation in oil constituents, and selection for oilseed cultivars with high content of valued industrial constituents is in progress.

Cannabis smoke contains thousands of organic and inorganic chemical compounds. This tar is chemically similar to that found in tobacco smoke,[88] and over fifty known carcinogens have been identified in cannabis smoke,[89] including; nitrosamines, reactive aldehydes, and polycylic hydrocarbons, including benz[a]pyrene.[90] Cannabis smoke is also inhaled more deeply than is tobacco smoke.[91] As of 2015, there is no consensus regarding whether cannabis smoking is associated with an increased risk of cancer.[92] Light and moderate use of cannabis is not believed to increase risk of lung or upper airway cancer. Evidence for causing these cancers is mixed concerning heavy, long-term use. In general there are far lower risks of pulmonary complications for regular cannabis smokers when compared with those of tobacco.[93] A 2015 review found an association between cannabis use and the development of testicular germ cell tumors (TGCTs), particularly non-seminoma TGCTs.[94] A 2015 analysis of six studies found little evidence that long-term or regular cannabis smoking was associated with lung cancer risk, though it could not rule out whether an association with heavy smoking exists.[95] Another 2015 meta-analysis found no association between lifetime cannabis use and risk of head or neck cancer.[96] Combustion products are not present when using a vaporizer, consuming THC in pill form, or consuming cannabis foods.[97]

The United Kingdom and Germany resumed commercial production in the 1990s. British production is mostly used as bedding for horses; other uses are under development. Companies in Canada, the UK, the United States, and Germany, among many others, process hemp seed into a growing range of food products and cosmetics; many traditional growing countries still continue to produce textile-grade fibre.
Mike, what kind of breast cancer (invasive ductal, I presume)? How many of her lymph nodes were positive? How big was the primary tumor? Reason I ask is that in women with Stage I or IIA tumors that are estrogen-and progesterone-receptor-positive and HER2-negative (ER+/PR+/HER2-) with three or fewer positive lymph nodes, there is a genomic assay test on a sample of the tumor, called OncotypeDX, that will tell doctors whether chemo is necessary or would even work at all. Medicare covers that test 100%.That type of breast cancer mentioned above, which I had as Stage IA, is treated in postmenopausal women with anti-estrogen drugs called aromatase inhibitors(aka AIs: anastrazole, letrozole, or exemestane)which have as a side effect joint pain. CBD oil is effective for this joint pain it is not, I repeat, NOT a substitute for chemo, radiation or these anti-estrogen drugs.So don’t assume your mom’s cancer will require chemo; but if it does, CBD helps with those side effects as well. If she lives in a state where medical marijuana is legal, there are doctors who sub-specialize in certifying applications for a medical marijuana card, and in the interim before the card is issued can advise as to the appropriate dose of CBD oil (legal and over-the-counter in all 50 states). Some (though not most) medical oncologists will certify their own patients’ medical marijuana card applications so she need not seek out another doctor; and will advise the appropriate dose for her symptoms. Once she gets her card, the “budtenders” in the licensed dispensaries can advise her as to the right CBD product (with or without THC), strength, and dosage. If she lives in a state where recreational weed is legal, the “budtenders” in the marijuana shops can steer her to the right strength of CBD oil and the right dosage.
On the other hand, marijuana-derived CBD and anything else derived from a cannabis plant was still classified by the DEA as a Schedule I drug (defined as a drug with "no currently accepted medical use and a high potential for abuse") until October 2018. In 2016, the DEA stated that all extracts containing more than one cannabinoid would remain classified as Schedule I. However, the approval of Epidiolex had an influence in changing this, and prescription CBD drugs with a THC content of below 0.1% have now been reclassified as Schedule 5, the lowest rating.

Essential (volatile) oil in hemp is quite different from hempseed oil. Examples of commercial essential oil product products are shown in Fig. 42. The essential oil is a mixture of volatile compounds, including monoterpenes, sesquiterpenes, and other terpenoid-like compounds that are manufactured in the same epidermal glands in which the resin of Cannabis is synthesized (Meier and Mediavilla 1998). Yields are very small—about 10 L/ha (Mediavilla and Steinemann 1997), so essential oil of C. sativa is expensive, and today is simply a novelty. Essential oil of different strains varies considerably in odor, and this may have economic importance in imparting a scent to cosmetics, shampoos, soaps, creams, oils, perfumes, and foodstuffs. Switzerland has been a center for the production of essential oil for the commercial market. Narcotic strains tend to be more attractive in odor than fiber strains, and because they produce much higher numbers of flowers than fiber strains, and the (female) floral parts provide most of the essential oil, narcotic strains are naturally adapted to essential oil production. Switzerland has permitted strains with higher THC content to be grown than is allowed in other parts of the world, giving the country an advantage with respect to the essential oil market. However, essential oil in the marketplace has often been produced from low-THC Cannabis, and the THC content of essential oil obtained by steam distillation can be quite low, producing a product satisfying the needs for very low THC levels in food and other commercial goods. The composition of extracted essential oil is quite different from the volatiles released around the fresh plant (particularly limonene and alpha-pinene), so that a pleasant odor of the living plant is not necessarily indicative of a pleasant-smelling essential oil. Essential oil has been produced in Canada by Gen-X Research Inc., Regina. The world market for hemp essential oil is very limited at present, and probably also has limited growth potential.
With respect to fiber, a “composite” is often defined as a material consisting of 30%–70% fiber and 70%–30% matrix (Bolton 1995). However, in North America particleboards and fiberboards, which generally contain less than 10% adhesive or matrix, are sometimes referred to as composites. This section addresses plastic-type composites. In plastics, fibers are introduced to improve physical properties such as stiffness, impact resistance, bending and tensile strength. Man-made fibers of glass, kevlar and carbon are most commonly used today, but plant fibers offer considerable cost savings along with comparable strength properties.

Whether the drug and non-drug, cultivated and wild types of Cannabis constitute a single, highly variable species, or the genus is polytypic with more than one species, has been a subject of debate for well over two centuries. This is a contentious issue because there is no universally accepted definition of a species.[53] One widely applied criterion for species recognition is that species are "groups of actually or potentially interbreeding natural populations which are reproductively isolated from other such groups."[54] Populations that are physiologically capable of interbreeding, but morphologically or genetically divergent and isolated by geography or ecology, are sometimes considered to be separate species.[54] Physiological barriers to reproduction are not known to occur within Cannabis, and plants from widely divergent sources are interfertile.[42] However, physical barriers to gene exchange (such as the Himalayan mountain range) might have enabled Cannabis gene pools to diverge before the onset of human intervention, resulting in speciation.[55] It remains controversial whether sufficient morphological and genetic divergence occurs within the genus as a result of geographical or ecological isolation to justify recognition of more than one species.[56][57][58]
Hi Diane, how did you go on with the CBD oil please. If it worked how long before you saw any results. I'm scared of flaring everything. Nerve damage across buttocks from a surgeon who found the nerve stuck to the bulge during a laminectomy operation and prised it off. I haven't sat for 5 years and getting worse. A muscle in my buttock is now throbbing constantly and causing pain to the muscle above. I've only started taking it today but the muscle pain is still as painful. Does it take a while for it to work. Only started on low dose to see what happens. Thank you Lyn
The 2014 US Farm Bill allows states that have passed their own industrial hemp legislation to grow industrial hemp for purposes of research and development. Several states — including Kentucky, Colorado, and Oregon — are already conducting hemp pilot projects. Many other states are currently pursuing similar legislation and programs. After many years of prohibition, American farmers are finally reacquainting themselves with industrial hemp.
Air-dried stem yields in Ontario have from 1998 and onward ranged from 2.6-14.0 tonnes of dry, retted stalks per hectare (1-5.5 t/ac) at 12% moisture. Yields in Kent County, have averaged 8.75 t/ha (3.5 t/ac). Northern Ontario crops averaged 6.1 t/ha (2.5 t/ac) in 1998. Statistic for the European Union for 2008 to 2010 say that the average yield of hemp straw has varied between 6.3 and 7.3 ton per ha.[67][68] Only a part of that is bast fiber. Around one tonne of bast fiber and 2-3 tonnes of core material can be decorticated from 3-4 tonnes of good-quality, dry-retted straw. For an annual yield of this level is it in Ontario recommended to add nitrogen (N):70–110 kg/ha, phosphate (P2O5): up to 80 kg/ha and potash (K2O): 40–90 kg/ha.[69] The average yield of dry hemp stalks in Europe was 6 ton/ha (2.4 ton/ac) in 2001 and 2002.[14]
An alternative to the gateway hypothesis is the common liability to addiction (CLA) theory. It states that some individuals are, for various reasons, willing to try multiple recreational substances. The "gateway" drugs are merely those that are (usually) available at an earlier age than the harder drugs. Researchers have noted in an extensive review that it is dangerous to present the sequence of events described in gateway "theory" in causative terms as this hinders both research and intervention.[259]

Germplasm for the improvement of hemp is vital for the future of the industry in North America. However, there are no publicly available germplasm banks housing C. sativa in North America. The hundreds of seed collections acquired for Small’s studies (reviewed in Small 1979) were destroyed in 1980 because Canadian government policy at that time envisioned no possibility that hemp would ever be developed as a legitimate crop. An inquiry regarding the 56 United States Department of Agriculture hemp germplasm collections supplied to and grown by Small and Beckstead (1973) resulted in the reply that there are no remaining hemp collections in USDA germplasm holdings, and indeed that were such to be found they would have to be destroyed. While hemp has been and still is cultivated in Asia and South America, it is basically in Europe that germplasm banks have made efforts to preserve hemp seeds. The Vavilov Institute of Plant Research in St. Petersburg, Russia has by far the largest germplasm collection of hemp of any public gene bank, with about 500 collections. Detailed information on the majority of hemp accessions of the Vavilov Institute can be found in Anon. (1975). Budgetary problems in Russia have endangered the survival of this invaluable collection, and every effort needs to be made to find new funding to preserve it. Maintenance and seed generation issues for the Vavilov hemp germplasm collection are discussed in a number of articles in the Journal of the International Hemp Association (Clarke 1998b; Lemeshev et al. 1993, 1994). The Gatersleben gene bank of Germany, the 2nd largest public gene bank in Europe, has a much smaller Cannabis collection, with less than 40 accessions (detailed information on the hemp accessions of the Gatersleben gene bank are available at Because hemp is regaining its ancient status as an important crop, a number of private germplasm collections have been assembled for the breeding of cultivars as commercial ventures (de Meijer and van Soest 1992; de Meijer 1998), and of course these are available only on a restricted basis, if at all.
A randomized, placebo-controlled, crossover pilot study of nabiximols in 16 patients with chemotherapy-induced neuropathic pain showed no significant difference between the treatment and placebo groups. A responder analysis, however, demonstrated that five patients reported a reduction in their pain of at least 2 points on an 11-point scale, suggesting that a larger follow-up study may be warranted.[55]
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
During the period from 1937 to the late 60s, the U.S. government understood and acknowledged that industrial hemp and marijuana were distinct varieties of the Cannabis plant. Hemp was no longer officially recognized as distinct from marijuana after the passage of the Controlled Substances Act (CSA) of 1970. This is despite the fact that a specific exemption for hemp was included in the CSA under the definition of marijuana. The recent federal court case HIA vs DEA has re-established acknowledgement of distinct varieties of Cannabis, and supports the exemption for non-viable seed and fiber and any products made from them.
...with due respect, your experience Locsta is almost precisely what happened with my....chihuahua. Degenerative disc disease, excruciating pain, prednisone worked, but couldn't keep her on it..pain killers and muscle relaxants didn't help, really thought I would have to put her down. Chi bloggers suggested CBD; gave PetReleaf a shot--like you, literally within minutes I could see the difference, in days she was pain free and now is back in charge of our world. The real key here is that with my dog, there is zero, nada, chance that there was any placebo effect...
Topicals represent a newer emerging market in medical marijuana products geared toward health and beauty. Cannabinoids can be absorbed through the skin for certain therapeutic benefits without any psychoactivity. Additionally, the essential oils in hemp and cannabis provide many benefits for skin health. From moisturizers to shampoos and deodorants, medical cannabis products continue to diversify.
According to the United States Department of Health and Human Services, there were 455,000 emergency room visits associated with cannabis use in 2011. These statistics include visits in which the patient was treated for a condition induced by or related to recent cannabis use. The drug use must be "implicated" in the emergency department visit, but does not need to be the direct cause of the visit. Most of the illicit drug emergency room visits involved multiple drugs.[72] In 129,000 cases, cannabis was the only implicated drug.[73][74]
All this means that scientists can still only obtain marijuana-derived CBD from farms licensed by the National Institute on Drug Abuse (which until this year meant only one farm owned by the University of Mississippi). As for whether you should have a preference for CBD that comes from hemp, marijuana, or a pure synthetically produced version, there are some theories that THC—and even the smell and taste of cannabis—might make CBD more effective, but Bonn-Miller says these ideas have yet to be proven.
After the Restoration of Independence in 1640, in order to recover the ailing Portuguese naval fleet, were encouraged its cultivation as the Royal Decree of D. John IV in 1656. At that time its cultivation was carried out in Trás-os-Montes, Zone Tower Moncorvo, more precisely in Vilariça Valley, fertile land for any crop irrigation, and a very large area, flat and very fertile culture still wide until the last century grew up tobacco, a plant that needs a large space to expand and grow, the area lies in the valley of Serra de Bornes.
"The dairy industry is really in trouble, and so, one of the things that I find really important is finding value-added products," Gilbert Jenkins said. "I am not an et. al scientist, I am not a dairy farmer, but I know about the crops that they grow. Having an opportunity to grow a crop -- even on just a portion of the acres -- that could bring in new income."
Cannabis sativa is an annual wind-pollinated plant, normally dioecious and dimorphic, although sometimes monoecious (mostly in several modern European fiber cultivars). Figure 2 presents the basic morphology of the species. Some special hybrids, obtained by pollinating females of dioecious lines with pollen from monoecious plants, are predominantly female (so-called “all-female,” these generally also produce some hermaphrodites and occasional males). All-female lines are productive for some purposes (e.g. they are very uniform, and with very few males to take up space they can produce considerable grain), but the hybrid seed is expensive to produce. Staminate or “male” plants tend to be 10%–15% taller and are less robust than the pistillate or “female” (note the comparatively frail male in Fig. 3). So prolific is pollen production that an isolation distance of about 5 km is usually recommended for generating pure-bred foundation seed. A “perigonal bract” subtends each female flower, and grows to envelop the fruit. While small, secretory, resin-producing glands occur on the epidermis of most of the above-ground parts of the plant, the glands are very dense and productive on the perigonal bracts, which are accordingly of central interest in marijuana varieties. The root is a laterally branched taproot, generally 30–60 cm deep, up to 2.5 m in loose soils, very near the surface and more branched in wet soils. Extensive root systems are key to the ability of hemp crops to exploit deep supplies of nutrients and water. The stems are erect, furrowed, and usually branched, with a woody interior, and may be hollow in the internodes. Although the stem is often woody, the species is frequently referred to as a herb or forb. Plants vary enormously in height depending on genetic constitution and environment (Fig. 4), but are typically 1–5 m (heights of 12 m or more in cultivation have been claimed).
"A CBD company may create a CBD oil, test it, and use the test results to create their label," Bonn-Miller says. "The problem is if they never test their product again, or they test it once a year, you have no idea whether each batch is the same as the first one that they used to create the label. The vast majority of companies are not using manufacturing standards that assure product consistency over time. Companies should be testing every batch they make and tossing batches that don't fall within the specs of their label."
In a new short film produced by Patagonia, Harvesting Liberty, Michael Lewis, a veteran and hemp grower in Kentucky, shares his encounter with the DEA. In 2014, after the passage of the Farm Bill, Lewis was keen to plant hemp in Kentucky. “[But] the DEA didn’t agree that we had a right to plant the crop. They said they would arrest us,” he says in the film. The matter ended up in the Louisville court, where a judge sided with the farmers. “[We] took our seeds up, got them registered and certified, and threw them into the ground before anyone could change their mind,” Lewis says.

At least 50% of patients who receive moderately emetogenic chemotherapy may experience delayed chemotherapy-induced N/V. Although selective neurokinin 1 antagonists that inhibit substance P have been approved for delayed N/V, a study was conducted before their availability to assess dronabinol, ondansetron, or their combination in preventing delayed-onset chemotherapy-induced N/V.[34] Ondansetron, a serotonin 5-hydroxytryptamine 3 (5-HT3) receptor antagonist, is one of the mainstay agents in the current antiemetic armamentarium. In this trial, the primary objective was to assess the response 2 to 5 days after moderately to severely emetogenic chemotherapy. Sixty-one patients were analyzed for efficacy. The total response–a composite endpoint–including nausea intensity, vomiting/retching, and use of rescue medications, was similar with dronabinol (54%), ondansetron (58%), and combination therapy (47%) when compared with placebo (20%). Nausea absence was greater in the active treatment groups (dronabinol 71%, ondansetron 64%, combination therapy 53%) when compared with placebo (15%; P < .05 vs. placebo for all). Occurrence rates for nausea intensity and vomiting/retching episodes were the lowest in patients treated with dronabinol, suggesting that dronabinol compares favorably with ondansetron in this situation where a substance P inhibitor would currently be the drug of choice.

Many monoecious varieties have also been described,[19] in which individual plants bear both male and female flowers.[20] (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.[21][22][23] Many populations have been described as sexually labile.[24][25][26]

Quality is a particular concern, because cannabis plants easily soak up heavy metals from pesticides and other contaminants, Marcu says. If you are buying online, look for a company that documents how it tests its products. (If the website doesn’t indicate this, call and ask.) “Buying from a reputable manufacturer is crucial, because it matters how the plant is cultivated and processed,” Dr. Maroon says. One clue that a company is cutting corners: too low a cost. Good CBD is pricey—a bottle of high-quality capsules is sold in Cohen’s office for $140. But for many, it’s worth the money. Roth spent $60 on her tiny bottle. But when her energy returned the day she started taking CBD, she decided that was a small price to pay.

All of this makes CBD remarkably difficult for even the most dedicated health care providers to manage safely. Dr. Kelly Knupp, an associate professor of pediatrics and neurology at the University of Colorado, and the director of the Dravet Syndrome program at Children’s Hospital Colorado, said families of epileptic children have tried to bring CBD oils to the hospital for testing. “They’re just concerned that they don’t know exactly who’s growing [the hemp],” Knupp said. “They know it’s not being regulated.” But because CBD is a Schedule I controlled substance, high-tech, regulated laboratories, like those at the University of Colorado, can’t accept, store, or test CBD oils, lest they risk prosecution. “There is no such lab that can take that product,” Knupp said, which leaves any testing up to the unregulated testing centers that cater to the cannabis industry.
Laboratory evidence indicated that cannabidiol may reduce THC clearance, increasing plasma concentrations which may raise THC availability to receptors and enhance its effect in a dose-dependent manner.[28][29] In vitro, cannabidiol inhibited receptors affecting the activity of voltage-dependent sodium and potassium channels, which may affect neural activity.[30] A small clinical trial reported that CBD partially inhibited the CYP2C-catalyzed hydroxylation of THC to 11-OH-THC.[31]
Another study examined the effects of a plant extract with controlled cannabinoid content in an oromucosal spray. In a multicenter, double-blind, placebo-controlled study, the THC:CBD nabiximols extract and THC extract alone were compared in the analgesic management of patients with advanced cancer and with moderate-to-severe cancer-related pain. Patients were assigned to one of three treatment groups: THC:CBD extract, THC extract, or placebo. The researchers concluded that the THC:CBD extract was efficacious for pain relief in advanced cancer patients whose pain was not fully relieved by strong opioids.[52] In a randomized, placebo-controlled, graded-dose trial, opioid-treated cancer patients with poorly controlled chronic pain demonstrated significantly better control of pain and sleep disruption with THC:CBD oromucosal spray at lower doses (1–4 and 6–10 sprays/day), compared with placebo. Adverse events were dose related, with only the high-dose group (11–16 sprays/day) comparing unfavorably with the placebo arm. These studies provide promising evidence of an adjuvant analgesic effect of THC:CBD in this opioid-refractory patient population and may provide an opportunity to address this significant clinical challenge.[53] An open-label extension study of 43 patients who had participated in the randomized trial found that some patients continued to obtain relief of their cancer-related pain with long-term use of the THC:CBD oromucosal spray without increasing their dose of the spray or the dose of their other analgesics.[54]

There is clear evidence that recreational cannabis can produce a transient toxic psychosis in larger doses or in susceptible individuals, which is said to characteristically resolve within a week or so of absence (Johns 2001). Transient psychotic episodes as a component of acute intoxication are well-documented (Hall et al 1994)

Cannabis can be prepared into various foods generally called ‘edibles’. It takes between 1-3 hours to feel the effects after eating cannabis.2 Impatient or naïve users may believe they have not taken enough to feel the effects, and if they consume more they may find later that the psychoactive effects are unpleasantly strong. When edible products have inconsistent levels of THC even experienced users may find it difficult to regulate the amount consumed.
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.
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
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.

Although global abnormalities in white matter and grey matter are not associated with cannabis abuse, reduced hippocampal volume is consistently found. Amygdalar abnormalities are sometimes reported, although findings are inconsistent.[105][106][107] Preliminary evidence suggests that this effect is largely mediated by THC, and that CBD may even have a protective effect.[108]
“Hemp is of high nutritional quality because it contains high amounts of unsaturated fatty acids… Linoleic acid and alpha-linolenic acid are the only two fatty acids that must be ingested and are considered essential to human health … 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…”  
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.

It is often claimed by growers and breeders of herbal cannabis that advances in breeding and cultivation techniques have increased the potency of cannabis since the late 1960s and early '70s when THC was first discovered and understood. However, potent seedless cannabis such as "Thai sticks" were already available at that time. Sinsemilla (Spanish for "without seed") is the dried, seedless inflorescences of female cannabis plants. Because THC production drops off once pollination occurs, the male plants (which produce little THC themselves) are eliminated before they shed pollen to prevent pollination. Advanced cultivation techniques such as hydroponics, cloning, high-intensity artificial lighting, and the sea of green method are frequently employed as a response (in part) to prohibition enforcement efforts that make outdoor cultivation more risky. It is often cited that the average levels of THC in cannabis sold in the United States rose dramatically between the 1970s and 2000, but such statements are likely skewed because undue weight is given to much more expensive and potent, but less prevalent samples.[241]
France is Europe's biggest producer (and the world's second largest producer) with 8,000 hectares cultivated.[80] 70-80% of the hemp fibre produced in 2003 was used for specialty pulp for cigarette papers and technical applications. About 15% was used in the automotive sector, and 5-6% was used for insulation mats. About 95% of hurds were used as animal bedding, while almost 5% was used in the building sector.[14] In 2010/2011, a total of 11,000 hectares (27,000 acres) was cultivated with hemp in the EU, a decline compared with previous year.[68][81]
