PMID 23390554. The most consistently reported brain alteration was reduced hippocampal volume which was shown to persist even after several months of abstinence in one study and also to be related to the amount of cannabis use Other frequently reported morphological brain alterations related to chronic cannabis use were reported in the amygdala the cerebellum and the frontal cortex...These findings may be interpreted as reflecting neuroadaptation, perhaps indicating the recruitment of additional regions as a compensatory mechanism to maintain normal cognitive performance in response to chronic cannabis exposure, particularly within the prefrontal cortex area.
No medication seemed to provide a great deal of relief for Harper’s symptoms. But in 2013, three years after their trip to Boston, Penny and Dustin caught an installment of CNN’s medical marijuana documentary and began researching what they could obtain in Texas, where medical marijuana is illegal. Their internet searches soon led them to HempMedsPx and Real Scientific Hemp Oil. The company sent Penny a vial of hemp oil, which she administered to Harper that September.
Hemp oil has never been as popular as other marijuana products. With little to no THC, CBD-rich strains of cannabis don’t deliver the pleasant buzz recreational users seek out in marijuana. In the 1970s, however, scientists found that cannabidiol was effective in reducing seizures. The brain’s endocannabinoid system contains receptors that respond to CBD, producing anticonvulsant effects. Being plant-derived and native to the brain’s own chemistry, CBD is therefore one of the most natural options for seizure treatment available today. Still, not many people took interest in CBD until 2013, when a CNN documentary special, Weed, hosted by the network’s chief medical correspondent, Dr. Sanjay Gupta, highlighted CBD’s effectiveness in combating seizures. Since then, demand for hemp oil products has exploded.
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.
A 2012 review found that the THC content in marijuana had increased worldwide from 1970 to 2009. It is unclear, however, whether the increase in THC content has caused people to consume more THC or if users adjust based on the potency of the cannabis. It is likely that the higher THC content allows people to ingest less tar. At the same time, CBD levels in seized samples have lowered, in part because of the desire to produce higher THC levels and because more illegal growers cultivate indoors using artificial lights. This helps avoid detection but reduces the CBD production of the plant.
My husband was diagnosed with ALS (amyotrophic lateral sclerosis) when he was 61 years old 4 years ago. The Rilutek (riluzole) did very little to help him. The medical team did even less. His decline was rapid and devastating. His arms weakened first, then his hands and legs. Last year, a family friend told us about Rich Herbs Foundation (RHF) and their successful ALS TREATMENT, we visited their website www. richherbsfoundation. com and ordered their ALS/MND Formula, i am happy to report the treatment effectively treated and reversed his Amyotrophic Lateral Sclerosis (ALS), most of the symptoms stopped, he is able to walk and able to ride his treadmill again, he is pretty active now.

In the 1950s, the Narcotics Control Act and the Boggs Act stiffened penalties for marijuana possession, with first-time offenses requiring two to 10 year sentences and a minimum $20,000 fine, according to PBS.org. Penalties were relaxed in the 1970s, but President Ronald Reagan increased federal penalties for marijuana possession in the 1980s. On the federal level, marijuana is now regulated under the Controlled Substances Act as a schedule 1 drug, meaning the government considers it to have a high potential for abuse with no legitimate medical or therapeutic uses.
Marijuana is the most common illegal drug reported in motor vehicle accidents. A 2012 meta-analysis found that cannabis use was associated with an increased risk of being involved in a motor vehicle crash. A 2016 review also found a statistically significant increase in crash risk associated with marijuana use, but noted that this risk was "of low to medium magnitude." The increase in risk of motor vehicle crash for cannabis use is between 2 and 3 times relative to baseline, whereas that for comparable doses of alcohol is between 6 and 15 times.
Senate Majority Leader Mitch McConnell (R-KY) introduced new legislation in April that would declassify non-psychoactive cannabis varieties -- more commonly referred to as hemp -- from the Controlled Substances Act. The legislative proposal comes as part of McConnell's Hemp Farming Act of 2018, which would remove barriers placed on banking access and water rights in addition to legalizing the crop.
“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.
If you live in a state where CBD is legal for your condition, it’s best to buy it from a state-regulated dispensary. But even there, oversight is uneven. “I feel safe being a cannabis consumer in Colorado, since the state tracks everything from seed to sale, but I didn’t the first few years after cannabis became legal,” when the rules were still taking shape, says Robyn Griggs Lawrence, the Boulder author of The Cannabis Kitchen Cookbook, which features recipes for cannabis edibles.
Fatty Acids. 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 gamma-linolenic 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. The essential fatty acids are available in other oils, particularly fish and flaxseed, but these tend to have unpleasant flavors compared to the mellow, slightly nutty flavor of hempseed oil. While the value of unsaturated fats is generally appreciated, it is much less well known that the North American diet is serious nutritionally unbalanced by an excess of linoleic over alpha-linonenic acid. In hempseed, linoleic and alpha-linolenic occur in a ratio of about 3:1, considered optimal in healthy human adipose tissue, and apparently unique among common plant oils (Deferne and Pate 1996). Gamma-linolenic acid or GLA is another significant component of hemp oil (1%–6%, depending on cultivar). GLA is a widely consumed supplement known to affect vital metabolic roles in humans, ranging from control of inflammation and vascular tone to initiation of contractions during childbirth. GLA has been found to alleviate psoriasis, atopic eczema, and mastalgia, and may also benefit cardiovascular, psychiatric, and immunological disorders. Ageing and pathology (diabetes, hypertension, etc.) may impair GLA metabolism, making supplementation desirable. As much as 15% of the human population may benefit from addition of GLA to their diet. At present, GLA is available in health food shops and pharmacies primarily as soft gelatin capsules of borage or evening primrose oil, but hemp is almost certainly a much more economic source. Although the content of GLA in the seeds is lower, hemp is far easier to cultivate and higher-yielding. It is important to note that hemp is the only current natural food source of GLA, i.e. not requiring the consumption of extracted dietary supplements. There are other fatty acids in small concentrations in hemp seed that have some dietary significance, including stearidonic acid (Callaway et al. 1996) and eicosenoic acid (Mölleken and Theimer 1997). Because of the extremely desirable fatty acid constitution of hemp oil, it is now being marketed as a dietary supplement in capsule form (Fig. 38).
Elias Anderson, one of the owners of Going Green, said representatives from HempMedsPx approached him after Krenzler published the lab’s findings on his blog. “They were like, ‘What are we gonna do about it?’” Anderson recalled, “And I was like, ‘Nothing. We have standards, and I stand behind my test results.’” Still, the company’s representatives were insistent and advised Anderson to have Kenzler take down the lab’s findings. In an email to the New Republic, Hard, the Medical Marijuana, Inc. spokesman, contended that the sample of hemp oil that Going Green Labs tested had been “tampered with” by a competitor after Krenzler obtained it. “HempMedsPX, if anything, told the lab they cannot publish results from products [for which] they had no chain of custody tracked,” Hard said, “and if they did—that could prove to be very bad for the lab.” He also characterized Krenzler and Anderson as “haters” of Medical Marijuana, Inc., and suggested that much of the criticism of the company and its products comes from commercial competitors.
There’s no definite amount that’s appropriate for everyone, but the ratio of CBD to THC will indicate how psychoactive the product is and if it’s legal in your state. The more CBD compared with THC, the less of a high, and vice versa. “Managing psychoactivity is key to successful cannabis therapy,” says Lee. “Amounts should be made clear on the label and lab-certified so people know what’s helping them and what’s not.”
Because C. sativa has been a neglected crop for so long in North America, there are only negligible genetic resources available on this continent. Most germplasm stocks of hemp are in Europe, and the largest and most important collection is the Vavilov Institute gene bank in Leningrad. Figure 11 shows THC concentrations in the Vavilov collection, as well as in our own collection, largely of European germplasm. A disturbingly high percentage of the collections have THC levels higher than 0.3%, making it difficult to incorporate these into breeding programs.
Full spectrum CBD does, however, bring with it the sticky issue of THC. The government regulates concentration levels of THC at 0.3 percent, an amount which results in minimal psychoactivity. But THC metabolites are stored in the fat cells of your body, building up over time. If you ever need to take a drug test, this could create an issue for you.
In 1924, Russian botanist D.E. Janichevsky concluded that ruderal Cannabis in central Russia is either a variety of C. sativa or a separate species, and proposed C. sativa L. var. ruderalis Janisch, and Cannabis ruderalis Janisch, as alternative names. In 1929, renowned plant explorer Nikolai Vavilov assigned wild or feral populations of Cannabis in Afghanistan to C. indica Lam. var. kafiristanica Vav., and ruderal populations in Europe to C. sativa L. var. spontanea Vav. In 1940, Russian botanists Serebriakova and Sizov proposed a complex classification in which they also recognized C. sativa and C. indica as separate species. Within C. sativa they recognized two subspecies: C. sativa L. subsp. culta Serebr. (consisting of cultivated plants), and C. sativa L. subsp. spontanea (Vav.) Serebr. (consisting of wild or feral plants). Serebriakova and Sizov split the two C. sativa subspecies into 13 varieties, including four distinct groups within subspecies culta. However, they did not divide C. indica into subspecies or varieties.
Henry Ford recognized the utility of hemp in early times. In advance of today’s automobile manufacturers, he constructed a car with certain components made of resin stiffened with hemp fiber (Fig. 19). Rather ironically in view of today’s parallel situation, Henry Ford’s hemp innovations in the 1920s occurred at a time of crisis for American farms, later to intensify with the depression. The need to produce new industrial markets for farm products led to a broad movement for scientific research in agriculture that came to be labeled “Farm Chemurgy,” that today is embodied in chemical applications of crop constituents.
A large, retrospective cohort study of 64,855 men aged 15 to 49 years from the United States found that Cannabis use was not associated with tobacco-related cancers and a number of other common malignancies. However, the study did find that, among nonsmokers of tobacco, ever having used Cannabis was associated with an increased risk of prostate cancer.
Understanding the mechanism of cannabinoid-induced analgesia has been increased through the study of cannabinoid receptors, endocannabinoids, and synthetic agonists and antagonists. Cannabinoids produce analgesia through supraspinal, spinal, and peripheral modes of action, acting on both ascending and descending pain pathways. The CB1 receptor is found in both the central nervous system (CNS) and in peripheral nerve terminals. Similar to opioid receptors, increased levels of the CB1 receptor are found in regions of the brain that regulate nociceptive processing. CB2 receptors, located predominantly in peripheral tissue, exist at very low levels in the CNS. With the development of receptor-specific antagonists, additional information about the roles of the receptors and endogenous cannabinoids in the modulation of pain has been obtained.[43,44]
Approximately 65% of sub-Saharan Africa’s agricultural land is degraded, according to data collected in 2015, resulting in food insecurity and a declining economy in a region where the agricultural industry employs more than half of the total labor force. Hemp’s soil nutrient replenishing properties could be the key to reviving crop production, providing a novel food source (hemp seeds) and boosting the agro-based economies of South Africa and other hemp-cultivating sub-Saharan countries.
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. 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. 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. 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.
Molecular analytical techniques developed in the late 20th century are being applied to questions of taxonomic classification. This has resulted in many reclassifications based on evolutionary systematics. Several studies of Random Amplified Polymorphic DNA (RAPD) and other types of genetic markers have been conducted on drug and fiber strains of Cannabis, primarily for plant breeding and forensic purposes. Dutch Cannabis researcher E.P.M. de Meijer and coworkers described some of their RAPD studies as showing an "extremely high" degree of genetic polymorphism between and within populations, suggesting a high degree of potential variation for selection, even in heavily selected hemp cultivars. They also commented that these analyses confirm the continuity of the Cannabis gene pool throughout the studied accessions, and provide further confirmation that the genus consists of a single species, although theirs was not a systematic study per se.
A panellized system of hemp-lime panels for use in building construction is currently under test in a European Union-funded research collaboration led by the University of Bath. The panels are being designed to assure high-quality construction, rapid on-site erection, optimal hygrothermal performance from day one, and energy- and resource-efficient buildings. The 36-month-long work programme aims to refine product and manufacturing protocols, produce data for certification and marketing, warranty, insurance cover, and availability of finance. It also includes the development of markets in Britain, France, and Spain.
