Then came World War II. The Japanese attack on Pearl Harbor shut off foreign supplies of "manila hemp" fiber from the Philippines. The USDA produced a film called "Hemp For Victory" to encourage U.S. farmers to grow hemp for the war effort. The U.S. government formed the War Hemp Industries Department and subsidized hemp cultivation. During the war, U.S. farmers grew about a million acres of hemp across the Midwest as part of that program.
Due to almost a century of misinformation about Cannabis, the distinction between Cannabis and its two primary species — hemp and marijuana — has become unclear to the many and some even consider the three plants to be one in the same. Because of this, the three terms are often used interchangeably, which has created difficulties when understanding the usage and benefits of Hemp vs Marijuana and Cannabis in general.
In 1925, a compromise was made at an international conference in The Hague about the International Opium Convention that banned exportation of "Indian hemp" to countries that had prohibited its use, and requiring importing countries to issue certificates approving the importation and stating that the shipment was required "exclusively for medical or scientific purposes". It also required parties to "exercise an effective control of such a nature as to prevent the illicit international traffic in Indian hemp and especially in the resin".[211][212] In the United States in 1937, the Marihuana Tax Act was passed,[213] and prohibited the production of hemp in addition to cannabis.
CBD’s action within the brain and body is quite complicated. To date, scientists have discovered more than a dozen different mechanisms of action, or ways that CBD affect us. It’s very likely that the beneficial effects of CBD are a result of the total of its activation of all of these biological pathways, not a single one in particular. Much more research is needed to fully understand the mechanisms by which CBD relieves ailments such as anxiety and seizures.
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.
This guide is an introduction to anyone looking to inform themselves about the reality of cannabis. It covers basic information about the marijuana plant, cannabis preparations, and the crucial elements of plant anatomy and science. This guide to marijuana also gives an overview of the most popular medical and recreational uses of cannabis. It offers a survey of the most important medical cannabis research while highlighting emerging trends in the legal cannabis market. The guide also introduces those new to cannabis to the many ways to consume marijuana, and much more.
Since the late 1970s, the federal Healthy People Initiative has been a visible component of the United States’ approach to improving population health.[11][12] In each decade, a new version of Healthy People is issued,[13] featuring updated goals and identifying topic areas and quantifiable objectives for health improvement during the succeeding ten years, with assessment at that point of progress or lack thereof. Progress has been limited to many objectives, leading to concerns about the effectiveness of Healthy People in shaping outcomes in the context of a decentralized and uncoordinated US health system. Healthy People 2020 gives more prominence to health promotion and preventive approaches and adds a substantive focus on the importance of addressing social determinants of health. A new expanded digital interface facilitates use and dissemination rather than bulky printed books as produced in the past. The impact of these changes to Healthy People will be determined in the coming years.[14]
CBD research is still in its infancy because both the substance itself and the cultivation of the plants from which it’s derived have long been illegal in the United States. And despite all those cookies you see for sale, CBD does seem to remain illegal, unless FDA approved. In December, hemp cultivation was legalized nationwide as a provision of the Agriculture Improvement Act of 2018. But the FDA released a statement explicating the agency’s stance on CBD’s legality: In short, the FDA does not recognize a distinction between cannabis- and hemp-derived CBD and, for the time being, considers both to be illegal—especially as a questionably safe food additive. Although CBD isn’t dangerous to healthy people, it can affect how the body metabolizes certain types of medication, which Blessing says could lead to overdose in some cases. (Because of the government shutdown, the FDA is unavailable to explain its stance or enforcement plans in further detail.)
Cannabis is used in three main forms: marijuana, hashish and hash oil. Marijuana is made from dried flowers and leaves of the cannabis plant. It is the least potent of all the cannabis products and is usually smoked or made into edible products like cookies or brownies (see Factsheet: Marijuana Edibles). Hashish is made from the resin (a secreted gum) of the cannabis plant. It is dried and pressed into small blocks and smoked. It can also be added to food and eaten. Hash oil, the most potent cannabis product, is a thick oil obtained from hashish. It is also smoked.
Nabiximols (brand name Sativex) is a patented medicine containing CBD and THC in equal proportions. The drug was approved by Health Canada in 2005 for prescription to treat central neuropathic pain in multiple sclerosis, and in 2007 for cancer related pain.[39][40] In New Zealand Sativex® is approved for use as an add-on treatment for symptom improvement in patients with moderate to severe spasticity due to Multiple Sclerosis who have not responded adequately to other anti-spasticity medication and who demonstrate clinically significant improvement in spasticity related symptoms during an initial trial of therapy.[41]

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.

Research suggests that CBD may exert some of its pharmacological action through its inhibition of fatty acid amide hydrolase (FAAH), which may in turn increase the levels of endocannabinoids, such as anandamide, produced by the body.[7] It has also been speculated that some of the metabolites of CBD have pharmacological effects that contribute to the biological activity of CBD.[38]
3. Is the CBD oil sold by Hempworx a bad product? No. To their credit, Hempworx does post third party lab reports posted on its website. Third party lab reports are the only way to really know what’s in the product you are buying. The Hempworx lab reports clearly show the amount of CBD and other cannabinoids including trace amounts of THC in the Hempworx CBD oil tincture. By all accounts, Hempworx CBD oil is of reasonably good quality. However, it’s worth noting that their posted lab reports do not show results of heavy metal, pesticide and residual solvents testing. The omission of these test results is concerning.
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.[112][113][114] Preliminary evidence suggests that this effect is largely mediated by THC, and that CBD may even have a protective effect.[115]
Despite the strange wording on the website, this certificate of analysis appears to show that this product does indeed have the stated level of cbd, about 10 mg per dropper.  It is confounding therefore, why they have tried to conflate cbd oil and hemp oil, even using ‘phytocannabinoid hemp oil’ on the ingredients label rather than just saying, cbd content.
The edible seeds contain about 30 percent oil and are a source of protein, fibre, and magnesium. Shelled hemp seeds, sometimes called hemp hearts, are sold as a health food and may be eaten raw; they are commonly sprinkled on salads or blended with fruit smoothies. Hemp seed milk is used as an alternative to dairy milk in drinks and recipes. The oil obtained from hemp seed can be used to make paints, varnishes, soaps, and edible oil with a low smoke point. Historically, the seed’s chief commercial use has been for caged-bird feed.
Those warning letters aside, there’s not a lot of federal oversight right now over the claims being made or the products that are being sold. Cohen warned against buying CBD products online, because “there’s a lot of scams out there.” Yet his clinic sells CBD, and he admits, “I say ‘Don’t buy online,’ but ours is worth doing, because we know what we’re doing. We ship all over.”

The phytocannabinoid cannabidiol (CBD), is a non-intoxicating molecule that results from the heating, or decarboxylation, of cannabidiolic acid, or CBDA. As popular as CBD has become in both the cannabis community and mainstream consumerism, its natural precursor, CBDA, is one of 114 unique cannabinoids found in cannabis. In most cultivars, or cultivated varieties of cannabis, CBD ranks low on the expression chart; there often isn’t much. However, following a explosive discovery in 2009 — it was noted that a handful of strains are rich in CBD over THC. Droves of CBD-rich cultivars began cropping up all across the US, resulting in a marked uptick in CBD availability across the states.
Fig. 11. Frequency histograms of THC concentration in germplasm collections. Left, collection of E. Small and D. Marcus; of the 167 accessions, 43% had THC levels >0.3%. Right, the collection of the Vavilov Institute, St. Petersburg; of the 278 accessions for which chemical analyses were reported in Anonymous (1975), about 55% had THC levels >0.3%.
The dosage on the back label said to give him 1/2 to a full dropper twice a day due to his weight. I gave him 1/2 a dropper with his food. A few hours later I noticed he was wobbling when he walked and tripped up the stairs and collapsed. I took him to my vet and he said there must be THC in the oil. I thought, how can a company sell this product knowing full well that THC is extremely TOXIC for animals! The rep I bought the vials from said I gave him too much and to follow the dosage chart she gave me. Why would I give him anymore of this poison to my dog? Also, why did the product sold to me not have the proper dosage label? Also, I found that this product is Full Spectrum which means there is THC in the product.
It is clear that there is a culture of idealistic believers in hemp in North America, and that there is great determination to establish the industry. As history has demonstrated, unbridled enthusiasm for largely untested new crops touted as gold mines sometimes leads to disaster. The attempt to raise silk in the US is probably the most egregious example. In 1826 a Congressional report that recommended the preparation of a practical manual on the industry resulted in a contagious desire to plant mulberries for silk production, with the eventual collapse of the industry, the loss of fortunes, and a legacy of “Mulberry Streets” in the US (Chapter 2, Bailey 1898). In the early 1980s in Minnesota, Jerusalem artichoke was touted as a fuel, a feed, a food, and a sugar crop. Unfortunately there was no market for the new “wonder crop” and hundreds of farmers lost about $20 million (Paarlberg 1990). The level of “hype” associated with industrial hemp is far more than has been observed before for other new crops (Pinfold Consulting 1998). Probably more so than any plant in living memory, hemp attracts people to attempt its cultivation without first acquiring a realistic appreciation of the possible pitfalls. American presidents George Washington and Thomas Jefferson encouraged the cultivation of hemp, but both lost money trying to grow it. Sadly in Canada in 1999 numerous farmers contracted to grow half of Canada’s crop area for hemp for the American-based Consolidated Growers and Processors, and with the collapse of the firm were left holding very large amounts of unmarketable grain and baled hemp straw. This has represented a most untimely setback for a fledgling industry, but at least has had a sobering effect on investing in hemp. In this section we emphasize why producers should exercise caution before getting into hemp.
"I have suffered with insomnia, anxiety and chronic back pain for years. With bulging and herniated discs from C3-C6 and T2-T7, I’m like a worm trying to get comfortable in bed for sleep. The pain is related to the insomnia. If I can get comfortable, I might be able to get some sleep. I tried epidural steroid injections in my spine 4 times last year. It still left me with needing more. Then my friend called me with the 750 product saying, 'I know you've been going through the pain, a friend gave this to me to try and it might work for you.'
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]
Hemp extract is taken from the whole plant and contains higher levels of CBD than hemp seed oil.  This is where the CBD levels come from.  However, we are confused by the labeling.  If we expect the 500 product to have 500 mg of CBD, are we right?  The label shows 500 mg of ‘phytocannabinoid hemp oil’.  The solution is that about 160% of that is CBD, with the other cannabinoids as a tag along.  This is effective. 

Answering the question “what is CBD oil” would be incomplete without mentioning the many CBD oil benefits. In addition to positively affecting the endocannabinoid system, CBD has been the focus of more than 23,000 published studies about cannabinoids in relation to various medical indications including anxiety, epilepsy, inflammation, cancer and chronic pain to name few. You can even find CBD for pets that is specially formulated to safely allow your pets to experience the natural benefits of CBD. For a more comprehensive look at these and other studies, visit our medical research and education page. Stay up-to-date on the latest developments in CBD and cannabis in our medical marijuana news section.

In addition to acting on the brain, CBD influences many body processes. That’s due to the endocannabinoid system (ECS), which was discovered in the 1990s, after scientists started investigating why pot produces a high. Although much less well-known than the cardiovascular, reproductive, and respiratory systems, the ECS is critical. “The ECS helps us eat, sleep, relax, forget what we don’t need to remember, and protect our bodies from harm,” Marcu says. There are more ECS receptors in the brain than there are for opioids or serotonin, plus others in the intestines, liver, pancreas, ovaries, bone cells, and elsewhere.
Been using CBD oil from HW for 6 months now and I feel ALIVE HAPPY it's un describable how great I feel and even though lots of stressful situations happened lately I was able to control my mood, anxiety, my pain has noticeably diminished (I get a only a few hours per month of pain now and when that happens I use the Relief cream that works wonders!! I noticed my skin has improved and I sleep longer then ever before!
Based on world production of fibers in 1999, about 54.5% was synthetic (of which 60.3% was polyester), 42.9% was plant fiber (of which 78.5% was cotton), and 2.6% was wool (Karus 2000). In addition to cotton, flax is the only other significant plant fiber crop grown in temperate regions of the world (kenaf has received some enthusiastic backing in the southern US in recent years, but is most cheaply produced in India, Bangladesh, and China). Flax held 2.7% of the world plant fiber market in 1999, while hemp had only 0.3% (Karus 2000). Hemp fiber can potentially replace other biological fibers in many applications, but also, as noted below, can sometimes compete with minerals such as glass fiber and steel. As forests diminish, cultivation of annual plants as fiber sources is likely to increase. While crop residues like cereal straw will probably supply much of the need, specialty fiber plants such as hemp also have potential. The four conditions that will need to be met are (after Bolton 1995): (1) the material should be produced at a large enough scale; (2) the price should be low enough; (3) the fiber characteristics should be adequate for the end use; and (4) proven technology should be available for the processing of the new raw material. Of these criteria only point 3 is adequately met at this time for hemp in North America, but this is to be expected in a crop that has only begun to be cultivated after an absence of many years.
What is clear, though, is the DEA’s classification of all cannabis extracts as Schedule 1 controlled substances. Even as more states “legalize it,” all forms of cannabis are still illegal under federal law. And that’s a problem for HempWorx distributors who have to move product. As the DEA spokeswoman told the Port City Daily news site in North Carolina, where marijuana is illegal but decriminalized: “The plant, for human consumption, is illegal, bottom line. If you ship it — then that’s interstate commerce, that’s trafficking, and so that’s a problem.”
For home cooks like me, I recommend CBD extra virgin olive oil because of its versatility. You can drizzle it on everything from salads to pizza and even brambleberry ice cream. I even make a miso-honey glaze while using a little bit of the stuff. In particular, I’m a big fan of Pot d’Huile, which was founded by San Francisco-based Yannick Crespo. It’s stellar. For one thing, it tastes exactly the way good EVOO should—with none of that “green” marijuana aftertaste. It also doesn’t remind me of Bertolli—not that there’s anything wrong with it. But you know, delicious EVOO is nothing like Bertolli. Crespo attributes Pot d’Huile’s non-compromising flavor with the ethanol extraction process that the company uses, which is slightly more expensive—in addition to using locally-sourced oil from Northern California. The flavor is so good that Pot d'Huile regularly hosts pop-up dinners with chefs who are so into it. (And if you ever find yourself in a city where they’re hosting, it’d be a shame to skip out.) But beyond all that, Pot d’Huile makes dosing easy: It’s 1mg of CBD per 1ml of olive oil. So all you’ll really need to incorporate CBD EVOO into your meals are measuring spoons. And yes, they do have THC olive oils as well—at $50 for 100ml. In the future, the company also has plans on creating a THC–CBD oil. Easy peasy.
Health science is the branch of science focused on health. There are two main approaches to health science: the study and research of the body and health-related issues to understand how humans (and animals) function, and the application of that knowledge to improve health and to prevent and cure diseases and other physical and mental impairments. The science builds on many sub-fields, including biology, biochemistry, physics, epidemiology, pharmacology, medical sociology. Applied health sciences endeavor to better understand and improve human health through applications in areas such as health education, biomedical engineering, biotechnology and public health.

You can rub CBD oil on your skin or drop it under your tongue; you can eat it as a sugarcoated gummy or drink it as a Goop-approved cocktail. There's evidence (some scientific, plenty anecdotal) that it helps with epileptic seizures, opioid addiction, PTSD, arthritis, anxiety, insomnia, nausea, chronic pain, and much more. If you believe the hype, CBD can do just about anything for your physical and mental health — and it won't get you high as a kite.
About half of the world market for hemp oil is currently used for food and food supplements (de Guzman 2001). For edible purposes, hempseed oil is extracted by cold pressing. Quality is improved by using only the first pressing, and minimizing the number of green seeds present. The oil varies in color from off-yellow to dark green. The taste is pleasantly nutty, sometimes with a touch of bitterness. Hemp oil is high in unsaturated fatty acids (of the order of 75%), which can easily oxidize, so it is unsuitable for frying or baking. The high degree of unsaturation is responsible for the extreme sensitivity to oxidative rancidity. The oil has a relatively short shelf life. It should be extracted under nitrogen (to prevent oxidation), protected from light by being kept in dark bottles, and from heat by refrigeration. Addition of anti-oxidants prolongs the longevity of the oil. Steam sterilization of the seeds, often required by law, allows air to penetrate and so stimulates rancidity. Accordingly, sterilized or roasted hemp seeds, and products made from hemp seed that have been subjected to cooking, should be fresh. The value of hemp oil from the point of view of the primary components is discussed below. In addition, it has been suggested that other components, including trace amounts of terpenes and cannabinoids, could have health benefits (Leizer et al. 2000). According to an ancient legend (Abel 1980), Buddha, the founder of Buddhism, survived a 6-year interval of asceticism by eating nothing but one hemp seed daily. This apocryphal story holds a germ of truth—hemp seed is astonishingly nutritional.
Mental illness is described as 'the spectrum of cognitive, emotional, and behavioral conditions that interfere with social and emotional well-being and the lives and productivity of people. Having a mental illness can seriously impair, temporarily or permanently, the mental functioning of a person. Other terms include: 'mental health problem', 'illness', 'disorder', 'dysfunction'.[37]
The Gateway Hypothesis states that cannabis use increases the probability of trying "harder" drugs. The hypothesis has been hotly debated as it is regarded by some as the primary rationale for the United States prohibition on cannabis use.[261][262] A Pew Research Center poll found that political opposition to marijuana use was significantly associated with concerns about health effects and whether legalization would increase marijuana use by children.[263]
Karl W. Hillig, a graduate student in the laboratory of long-time Cannabis researcher Paul G. Mahlberg[78] at Indiana University, conducted a systematic investigation of genetic, morphological, and chemotaxonomic variation among 157 Cannabis accessions of known geographic origin, including fiber, drug, and feral populations. In 2004, Hillig and Mahlberg published a chemotaxonomic analysis of cannabinoid variation in their Cannabis germplasm collection. They used gas chromatography to determine cannabinoid content and to infer allele frequencies of the gene that controls CBD and THC production within the studied populations, and concluded that the patterns of cannabinoid variation support recognition of C. sativa and C. indica as separate species, but not C. ruderalis.[53] The authors assigned fiber/seed landraces and feral populations from Europe, Central Asia, and Turkey to C. sativa. Narrow-leaflet and wide-leaflet drug accessions, southern and eastern Asian hemp accessions, and feral Himalayan populations were assigned to C. indica. In 2005, Hillig published a genetic analysis of the same set of accessions (this paper was the first in the series, but was delayed in publication), and proposed a three-species classification, recognizing C. sativa, C. indica, and (tentatively) C. ruderalis.[56] In his doctoral dissertation published the same year, Hillig stated that principal components analysis of phenotypic (morphological) traits failed to differentiate the putative species, but that canonical variates analysis resulted in a high degree of discrimination of the putative species and infraspecific taxa.[79] Another paper in the series on chemotaxonomic variation in the terpenoid content of the essential oil of Cannabis revealed that several wide-leaflet drug strains in the collection had relatively high levels of certain sesquiterpene alcohols, including guaiol and isomers of eudesmol, that set them apart from the other putative taxa.[80] Hillig concluded that the patterns of genetic, morphological, and chemotaxonomic variation support recognition of C. sativa and C. indica as separate species. He also concluded there is little support to treat C. ruderalis as a separate species from C. sativa at this time, but more research on wild and weedy populations is needed because they were underrepresented in their collection.
Dosage is important, because CBD can have side effects—the most common are tiredness, diarrhea, and changes in appetite and weight—so it’s best not to take more than you need. As CBD becomes more prevalent, says J. Michael Bostwick, M.D., a psychiatrist at Mayo Clinic in Rochester, MN, “I’m reasonably certain new kinds of side effects will emerge.”
