Although hemp and marijuana are both varieties of cannabis, there is a difference between them. The differences between these cannabis varieties are primarily evident in the way each plant is used. These differences are also documented in the language, laws, and regulations that apply to each variety. In this introduction to hemp, we’ll break down the anatomy, history, use, and legality of the hemp plant to get to the heart of not only what distinguishes it from marijuana, but also what makes it such a viable, versatile commodity.
Marijuana looks contrastingly different from hemp. When you observe their leaves, marijuana’s shape tends to either be broad leafed, a tight bud, or look like a nugget with organd hairs. Hemp, on the other hand, has skinnier leaves that’s concentrated at the top. Few branches or leaves exist below the top part of the plant. When you observe the plants from afar, marijuana looks like a short fat bush. Hemp is typically skinnier and taller (up to 20 ft). At times, it almost looks like long ditchweed – hemp was actually found to grow among weeds in Nebraska. In general, when you compare a marijuana farm with those of industrial hemp, you’ll notice that they are clearly very different from one another.

• Is there a batch number? You know how you check your raw chicken or bagged lettuce every time there's a recall to make sure the one you bought isn't going to make you sick? You should be able to do that with CBD products too. "This is a huge indicator as to whether they are following good manufacturing practices," says Beatty. "There should be a way to identify this product in case it was improperly made so the company can carry out a recall."
Our reviews also include the ingredients and a description of the scent and texture of each CBD topical. We tried to remain neutral in our descriptions of each product, since each consumer’s experience is subjective. These are all high-quality CBD creams, balms and salves, but you may find you prefer one scent over another. You might love or hate menthol. Some people prefer a light texture, while other buyers are looking for CBD topicals to use in a massage.
Hemp, (Cannabis sativa), also called industrial hemp, plant of the family Cannabaceae cultivated for its fibre (bast fibre) or its edible seeds. Hemp is sometimes confused with the cannabis plants that serve as sources of the drug marijuana and the drug preparation hashish. Although all three products—hemp, marijuana, and hashish—contain tetrahydrocannabinol (THC), a compound that produces psychoactive effects in humans, the variety of cannabis cultivated for hemp has only small amounts of THC relative to that grown for the production of marijuana or hashish.
Sean McAllister, one of the researchers at California Pacific, was studying the effects of Cannabidiol(CBD). Pierre Desprez, a molecular biologist researcher, began studying ID-1, the gene that causes cancer to spread, about 20 years ago. The two combined their research and introduced CBD to cancer cells containing ID-1 in a petri dish. They found that CBD stopped the metastasis of the cancer cells.
Prior to the Hemp Farming Act of 2018, 41 states had passed industrial hemp-related legislation. 39 of those states legalized statewide hemp cultivation programs that defined hemp specifically to differentiate it from marijuana, establish licensing requirements, and regulate production. The Hemp Farming Act now requires state departments of agriculture to consult with their governors and chief law enforcement officers on a hemp regulatory program, which will then be submitted to the United States Secretary of Agriculture for approval. According to Section 297B of the bill, state hemp regulatory programs must include a system to maintain information on all land on which hemp is cultivated, procedures for testing THC levels in hemp, and procedures for disposing of products that violate THC content restrictions.
Hempseed's amino acid profile is comparable to other sources of protein such as meat, milk, eggs and soy. Protein digestibility-corrected amino acid scores (PDCAAS), which attempt to measure the degree to which a food for humans is a "complete protein", were 0.49–0.53 for whole hemp seed, 0.46–0.51 for hempseed meal, and 0.63–0.66 for hulled hempseed.
I recently have started to experiment with forms of CBD as a “last resort” for my neck pain. I was in 2 car accidents in the past, and I’m a full time hairstylist. I often have trouble sleeping, carrying out a full days work and light exercise. The pain was starting to severely effect how I go about my daily life with years of physical therepy and chiropractic visits nothing was helping.
Visit a dog park in a state where cannabis is legal, and you’re sure to overhear someone recommend giving CBD to their pet. Similar to the way we talk about CBD and humans, there is a plethora of examples where CBD might help–anxiety when traveling or going to the vet, pain maintenance, using THC as a tumor inhibitor, etc. If you Google search “cbd and pets” right now, the results show three times the options of “pet-friendly” products to buy as there are educational resources. There is no question that people are already medicating their dogs with forms of cannabis and CBD extracts.
Fig. 5. Typical architecture of categories of cultivated Cannabis sativa. Top left: narcotic plants are generally low, highly branched, and grown well-spaced. Top right: plants grown for oilseed were traditionally well-spaced, and the plants developed medium height and strong branching. Bottom left: fiber cultivars are grown at high density, and are unbranched and very tall. Bottom center: “dual purpose” plants are grown at moderate density, tend to be slightly branched and of medium to tall height. Bottom right: some recent oilseed cultivars are grown at moderate density and are short and relatively unbranched. Degree of branching and height are determined both by the density of the plants and their genetic background.
Keep in mind that CBD levels may vary from crop to crop—even from plant to plant. However, below are some strains that have been bred to contain higher CBD levels, so they might be a good place to start. Check the map on their strain page to see if these are sold at a dispensary near you. We also recommend checking with dispensaries about the specifics of their strains’ CBD levels. It’s always a good idea to purchase only lab-tested products that clearly state the CBD/THC levels so you know what kind of experience to expect.
Although banned by federal law, measurable doses of potent CBD-rich cannabis remedies are available in many non-smokable forms and can be utilized in various ways. The time of onset and duration of effect vary depending on the method of administration. CBD-rich cannabis oil products can be taken sublingually, orally (as edibles, lozenges, beverages, tinctures, and gel caps), or applied topically.
Bonn-Miller also explained that it's imperative to exhaust the traditional and established front-line treatments that are available before seeking out these products. "CBD is not really a first-line treatment for anything," he said. "You don’t want situations where somebody says, 'I have cancer I'm going to forgo chemotherapy because I read something about CBD or THC helping with cancer.'" That's not a good idea, Bonn-Miller said. "Not only is the science not there, but you may end up worse off."
^ 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.

In the mid 1990s, the EU provided subsidization for hemp cultivation of ca. $1,050/ha. This support was instrumental in developing a hemp industry in western Europe. However, no comparable support is available in North America, and indeed those contemplating entering into hemp cultivation are faced with extraordinary costs and/or requirements in connection with licensing, security, THC analysis, and record keeping. Those involved in value-added processing and distribution are also faced with legal uncertainties and the regular threat of idiosyncratic, indeed irrational actions of various governments. Simply displaying a C. sativa leaf on advertising has led to the threat of criminal charges in the last decade in several G8 countries. Attempting to export or import hemp products among countries is presently a most uncertain activity.
All available evidence indicates that long term use of PurCBD+ causes no side effects; however, PurCBD+ has only truly been available for pets for a couple years. The most common reason our customers cite for using CBD is to replace prescription drugs that have a known history of long term side effects. Always consult your veterinarian and use our dosing chart/schedule to coordinate the use of dietary supplements like PurCBD with prescription medications.
Cannabis contains a seemingly unique class of chemicals, the cannabinoids, of which more than 60 have been described, but only a few are psychoactive. Cannabinoids are produced in specialized epidermal glands, which differ notably in distribution on different organs of the plant (high concentrations occur on the upper surface of the young leaves and young twigs, on the tepals, stamens, and especially on the perigonal bract). Given this distribution, the glands would seem to be protective of young and reproductive above-ground tissues (the roots lack glands). Two classes of epidermal glands occur—stalked and sessile (Fig. 8), but in either case the glandular cells are covered by a sheath under which resin is accumulated, until the sheath ruptures, releasing resin on the surface. The resin is a sticky mixture of cannabinoids and a variety of terpenes. The characteristic odor of the plant is due to the abundant terpenes, which are not psychoactive. The more important cannabinoids are shown in Fig. 9. In the plant the cannabinoids exist predominantly in the form of carboxylic acids, which decarboxylate with time or when heated. Delta-9-tetrahydrocannabinol (D9-THC, or simply THC) is the predominant psychoactive component. Other THC isomers also occur, particularly D8-THC, which is also psychoactive. Technically, the euphoric psychological effects of THC are best described by the word psychotomimetic. Cannabidiol (CBD) is the chief non-psychotomimetic cannabinoid. A THC concentration in marijuana of approximately 0.9% has been suggested as a practical minimum level to achieve the (illegal) intoxicant effect, but CBD (the predominant cannabinoid of fiber and oilseed varieties) antagonizes (i.e. reduces) the effects of THC (Grotenhermen and Karus 1998). Concentrations of 0.3% to 0.9% are considered to have “only a small drug potential” (Grotenhermen and Karus 1998). Some cannabinoid races have been described, notably containing cannabichromene (particularly in high-THC forms) and cannabigerol monomethyl ether (in some Asian strains). The biosynthetic pathways of the cannabinoids are not yet satisfactorily elucidated, although the scheme shown in Fig. 10 is commonly accepted. At least in some strains, THC is derived from cannabigerol, while in others it may be derived from CBD. CBN and D8-THC are considered to be degradation products or analytical artifacts (Pate 1998a).
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.
Marijuana is the most popular illicit drug in the world, for no reason other than the fact that it produces a psychoactive chemical called tetrahydrocannabinol. Still, recreational marijuana use, which involves pursuing the euphoric sensations produced by cannabis consumption, is steadily becoming more and more legal, both in the United States and abroad.
Carbon dioxide is passed through the plant material at a very specific temperature and pressure. Carbon dioxide, which is normally a gas at (or above) room temperature, can be pressurized until it becomes so dense that it takes on some of the properties of a liquid while still maintaining the fluid dynamics of a gas. In this state, CO2 is known as a supercritical fluid.
The earliest recorded uses date from the 3rd millennium BC. Since the early 20th century, cannabis has been subject to legal restrictions. The possession, use, and sale of cannabis is illegal in most countries of the world. Medical cannabis refers to the physician-recommended use of cannabis, which takes place in Canada, Belgium, Australia, the Netherlands, Germany, Spain, and 33 U.S. states. In September 2018, cannabis was legalized in South Africa while Canada legalized recreational use of cannabis in October 2018.
Both Bonn-Miller and Ward stress that it's up to the consumer to be well-educated about the material they're purchasing and the research that's out there. "The companies that are creating [cannabis oils] are offering lots of claims about its use that are not necessarily substantiated by any research," Bonn-Miller said. So "I think there needs to be, from a consumer standpoint, a lot of vigilance," he added.
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.”
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.
There is reasonable evidence from prospective epidemiological studies which suggests that cannabis use can precipitate schizophrenia in persons who are vulnerable because of a personal or family history of schizophrenia. There is also evidence that a genetic vulnerability to psychosis increases the risk that cannabis users will develop psychosis (McGuire et al., 1995; Arseneault et al., 2002; Verdoux et al., 2002). A casual relationship also has biological plausibility in that the cannabinoid and dopaminergic neurotransmitter systems interact in animals. D'Souza and colleagues (1999) have shown in a provocation study that THC produces a dose-dependent increase in psychotic symptoms under double-blind placebo conditions; and Caspi and colleagues (2005) have shown an interaction between specific alleles of the COMT allele and psychotogenic effects of cannabis. If these results can be replicated and extended, they will increase the likelihood that cannabis can be a contributory cause of psychosis in vulnerable individuals.
As a physical therapist I have access to many modalities for pain. Specifically back pain that is not a radicular pain ( think disc problems) but sore muscle sprain/strain is common. Of all the modalities I have used, CBD transdermal is one of the most effective treatments. Pain just melts away in a matter of minutes without any smell or sensation.
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.
Cannabis, especially the cannabinoid CBD, has also demonstrated its abilities as a powerful anti-convulsant. This property is what accounts for cannabis’ ability to reduce the severity and frequency of seizures, especially for people with epilepsy. In the United States, epilepsy is the most widely adopted qualifying condition for medical cannabis use, especially for children.
Unfortunately, because this is a supplement we're not allowed to make medical claims regarding its use as a treatment or cure. However, this is the exact reason we began using this product on our own pets. (Our founding pets were diagnosed with cancer; one was 16 and the other was 8.) We used phytocannabinoidas palliative care for appetite and pain management.
Multiple sclerosis (MS). A prescription-only nasal spray product (Sativex, GW Pharmaceuticals) containing both 9-delta-tetrahydrocannabinol (THC) and cannabidiol has been shown to be effective for improving pain, muscle-tightness, and urination frequency in people with MS. This product is used in over 25 countries outside of the United States. But there is inconsistent evidence on the effectiveness of cannabidiol for symptoms of multiple sclerosis when it is used alone. Some early research suggests that using a cannabidiol spray under the tongue might improve pain and muscle tightness, but not muscle spasms, tiredness, bladder control, mobility, or well-being and quality of life in patients with MS.
But he wasn’t finished. In February of 1980, Dr. Mechoulam teamed up with South American researchers to publish a study regarding cannabis and epilepsy. This study is seen as one of the earliest double-blind studies of CBD on clinical subjects. The study Dr. Mechoulam and his team conducted included 16 people, many of whom were children, who all suffered from severe epilepsy. The results were startling: Every subject who received CBD experienced improvement in their condition with little to no side effects. This anticonvulsant study has since proven to be an integral milestone in the world of clinical marijuana research, but largely went unnoticed at the time.
CBD has really helped me reduce my anxiety and difficulty to focus while studying. I used to fidget quite a bit when i was sitting for a long time although i never had learning disabilities of any sort. Now i have no problem sitting and reading for long times. This stuff has turned my brain into a Ferrarri engine in terms of learning, I’m going through new concepts really fast it’s pretty exciting. All this with less than 10 mg per day of CBD (a few drops sublingually throughout the day, from a concentrated product). If only it was easier to get good quality stuff.
Cannabidiol (CBD), the non-psychoactive compound found in the Marijuana plant, has become a fast-growing topic due to the wide of array of medical benefits it provides for people around the world. CBD can be used to provide relief for over fifty conditions including anxiety, depression, chronic pain, and more! If you or a loved one is experiencing any of these conditions, CBD may provide the relief they need. Included in those loved ones aren’t just the ones with two legs.
“Industrial hemp, along with all strains of cannabis, are decades behind other agricultural crops in terms of improved plant genetics,” said Arcadia Chief Financial Officer Matt Plavan. “With the explosive market growth projected in the industrial hemp and derivative markets, growers will need the very best hemp strains to meet demand, minimize waste, and ensure consistent quality.”
Cannabidiol has antipsychotic effects. The exact cause for these effects is not clear. But cannabidiol seems to prevent the breakdown of a chemical in the brain that affects pain, mood, and mental function. Preventing the breakdown of this chemical and increasing its levels in the blood seems to reduce psychotic symptoms associated with conditions such as schizophrenia. Cannabidiol might also block some of the psychoactive effects of delta-9-tetrahydrocannabinol (THC). Also, cannabidiol seems to reduce pain and anxiety.
When considering administering CBD, your first concern should be to keep them safe. This is especially important because animals can react adversely to some every-day substances like chocolate, raisins, and coffee, etc. Likewise, you NEVER want to feed your dog a product that contains THC, since it has psychoactive properties that will be making your animal “high,” and could cause extreme stress, confusion, or other medical problems.
Both CBD oil and cream have shown to have powerful effects on alleviating pain. They each have their own unique benefits and can both be used to relieve pain, regardless of what the source of the pain may be. Ultimately, the choice between which format to use will depend on the users' specific preferences, as they are both highly effective in reducing pain and many other discomforts.
Devinsky puts more weight behind the scientific advancements: In June, the FDA approved an epilepsy drug called Epidiolex, which contains a purified form of CBD oil. In controlled clinical trials, the drug was proven to reduce seizures in people with Dravet syndrome and Lennox-Gastaut syndrome — and it didn't produce as many of the unpleasant side-effects that come with other epilepsy medications.
Van Roekel (1994) has pointed out that Egyptian papyrus sheets are not “paper,” because the fiber strands are woven, not “wet-laid;” the oldest surviving paper is over 2,000 years of age, from China, and was made from hemp fiber (Fleming and Clarke 1998). Until the early 19th century, hemp, and flax were the chief paper-making materials. In historical times, hemp rag was processed into paper. Using hemp directly for paper was considered too expensive, and in any event the demand for paper was far more limited than today. Wood-based paper came into use when mechanical and chemical pulping was developed in the mid 1800s in Germany and England. Today, at least 95% of paper is made from wood pulp.
Check Dr. Stephen Porges’ work, as well as Stanley Rosenburg. Both treat trauma and the vagus nerve’s role in bodily symptoms, which cause a lot of the symptoms you mention, as well as other people here. Some of Stanley Rosenburg’s simple exercises along with Stephen Porges’ work, can realign the vagus nerve and when done regularly have a cumulative effect. Basically, most symptoms, even seizures can be caused by misalignments and/or contracted muscles, (even the tiniest muscle in the human body, the stapedius muscle when chronically contracted can cause havoc on body) all under the umbrella of the vagus nerve (polyvagal nervous system). This is very well researched and is cutting edge treatment without the use of drugs of any kind. Some of Porges’ treatments use music, believe it or not, specially designed headsets with bone conduction. But please research, there are therapists trained in this field and in meantime, you can self-apply Stanley Rosenburg’s Basic Exercise, as well as others, first and you will see drastic results.
This mint-green bath bomb, made by Los Angeles-based De La Beuh, combines the invigorating aromatherapy of peppermint oil with the pain relief benefits of CBD. I sat in the bath with this bath bomb soak for an hour—until the water ran cold—when I had both cramps and lower back aches, and while it doesn’t beat ingesting a painkiller, it did help soothe my pains so that I fell asleep as soon as I hit the pillow. De La Beuh sells bath bombs in many varieties—including a glittery Kaleidoscope version that will turn your bath into “unicorn” colors—so your preference just depends on your preferred aroma.
Separation of hurd and bast fiber is known as decortication. Traditionally, hemp stalks would be water-retted first before the fibers were beaten off the inner hurd by hand, a process known as scutching. As mechanical technology evolved, separating the fiber from the core was accomplished by crushing rollers and brush rollers, or by hammer-milling, wherein a mechanical hammer mechanism beats the hemp against a screen until hurd, smaller bast fibers, and dust fall through the screen. After the Marijuana Tax Act was implemented in 1938, the technology for separating the fibers from the core remained "frozen in time". Recently, new high-speed kinematic decortication has come about, capable of separating hemp into three streams; bast fiber, hurd, and green microfiber.
Although still considered to be quite controversial, a growing number of pet owners are discovering the benefits of CBD for dogs, especially their chronically ill companions. In this article I'll introduce you to some of the proven and assumed health benefits of CBD oil for dogs so that you can decide for yourself if this is right for your pooch or not.
Probably indigenous to temperate Asia, C. sativa is the most widely cited example of a “camp follower.” It was pre-adapted to thrive in the manured soils around man’s early settlements, which quickly led to its domestication (Schultes 1970). Hemp was harvested by the Chinese 8500 years ago (Schultes and Hofmann 1980). For most of its history, C. sativa was most valued as a fiber source, considerably less so as an intoxicant, and only to a limited extent as an oilseed crop. Hemp is one of the oldest sources of textile fiber, with extant remains of hempen cloth trailing back 6 millennia. Hemp grown for fiber was introduced to western Asia and Egypt, and subsequently to Europe somewhere between 1000 and 2000 BCE. Cultivation in Europe became widespread after 500 ce. The crop was first brought to South America in 1545, in Chile, and to North America in Port Royal, Acadia in 1606. The hemp industry flourished in Kentucky, Missouri, and Illinois between 1840 and 1860 because of the strong demand for sailcloth and cordage (Ehrensing 1998). From the end of the Civil War until 1912, virtually all hemp in the US was produced in Kentucky. During World War I, some hemp cultivation occurred in several states, including Kentucky, Wisconsin, California, North Dakota, South Dakota, Minnesota, Indiana, Illinois, Ohio, Michigan, Kansas, and Iowa (Ehrensing 1998). The second world war led to a brief revival of hemp cultivation in the Midwest, as well as in Canada, because the war cut off supplies of fiber (substantial renewed cultivation also occurred in Germany for the same reason). Until the beginning of the 19th century, hemp was the leading cordage fiber. Until the middle of the 19th century, hemp rivaled flax as the chief textile fiber of vegetable origin, and indeed was described as “the king of fiber-bearing plants,—the standard by which all other fibers are measured” (Boyce 1900). Nevertheless, the Marihuana Tax Act applied in 1938 essentially ended hemp production in the United States, although a small hemp fiber industry continued in Wisconsin until 1958. Similarly in 1938 the cultivation of Cannabis became illegal in Canada under the Opium and Narcotics Act.
