The use of Cannabis for seed oil (Fig. 36) began at least 3 millennia ago. Hempseed oil is a drying oil, formerly used in paints and varnishes and in the manufacture of soap. Present cultivation of oilseed hemp is not competitive with linseed for production of oil for manufacturing, or to sunflower and canola for edible vegetable oil. However, as noted below, there are remarkable dietary advantages to hempseed oil, which accordingly has good potential for penetrating the salad oil market, and for use in a very wide variety of food products. There is also good potential for hemp oil in cosmetics and skin-care products.
In the 1990s, European firms introduced lines of hemp oil-based personal care products, including soaps, shampoos, bubble baths, and perfumes. Hemp oil is now marketed throughout the world in a range of body care products, including creams, lotions, moisturizers, and lip balms. In Germany, a laundry detergent manufactured entirely from hemp oil has been marketed. Hemp-based cosmetics and personal care products account for about half of the world market for hemp oil (de Guzman 2001).
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.

In states with medical cannabis laws, consumers should try to purchase cannabis from licensed suppliers who share their test results, which hopefully validate their products’ robust cannabinoid and terpenoid profiles. If you’re looking to purchase hemp through an online outlet, research your purchase beforehand to ensure that you aren’t being duped.
Still, Blessing notes, amounts below 100 milligrams haven’t even been tested, so it’s not impossible that small amounts may have some effects. As far as anyone knows, heating up CBD doesn’t degrade its effects, and early evidence suggests that taking it along with high-fat food (like a dessert) aids the body’s absorption of the chemical. Beyond that, all anyone has is guesswork. By Chloe didn’t respond to a detailed list of questions about its sourcing and dosing, but I tried a few of the company’s CBD treats anyway. They were all incredibly tasty, and after consuming three cookies in the course of 24 hours, I accidentally fell asleep on my couch at an indeterminate time of the evening and woke up at 4:30 in the morning. Was it the CBD, or was I just tired? Maybe it was a classic placebo effect, in which I expected to be relaxed and became so.

"Between 1914 and 1933, in an effort to stem the use of Cannabis flowers and leaves for their psychotropic effects, 33 states passed laws restricting legal production to medicinal and industrial purposes only.37 The 1937 Marihuana Tax Act defined hemp as a narcotic drug, requiring that farmers growing hemp hold a federal registration and special tax stamp, effectively limiting further production expansion.

In 1937, the Marijuana Tax Act strictly regulated the cultivation and sale of all cannabis varieties. The Controlled Substances Act of 1970 classified all forms of cannabis — including hemp — as a Schedule I drug, making it illegal to grow it in the United States (which is why we’re forced to import hemp from other countries as long as it contains scant levels of THC — 0.3% is the regulation for hemp cultivation in the European Union and Canada). As a result of this long-term prohibition, most people have forgotten the industrial uses of the plant and continue to misidentify hemp with its cannabis cousin, marijuana.
The most valid claims to environmental friendliness of hemp are with respect to agricultural biocides (pesticides, fungicides, herbicides). Cannabis sativa is known to be exceptionally resistant to pests (Fig. 51), although, the degree of immunity to attacking organisms has been greatly exaggerated, with several insects and fungi specializing on hemp. Despite this, use of pesticides and fungicides on hemp is usually unnecessary, although introduction of hemp to regions should be expected to generate local problems. Cannabis sativa is also relatively resistant to weeds, and so usually requires relatively little herbicide. Fields intended for hemp use are still frequently normally cleared of weeds using herbicides, but so long as hemp is thickly seeded (as is always done when hemp is grown for fiber), the rapidly developing young plants normally shade out competing weeds.

Just read your article about CBD oil and checked the label on the oil I bought 9 months ago from a legal dispensary in Pendleton, Oregon. Across from the Subway. It lists herbs and supplements long before CBD oil and it is a derivative of Hemp oil. I paid $52 for one ounce (30 ml). I had not done any research prior to my purchase and relied on the folks at the marijuana shop to sell me a good product. Buyer beware is the best advice I got from this article. I have not achieved any pain relief from this product and use about 1 ml under my tongue with the dropper in the bottle. I intend to find a full spectrum CBD oil and I hope to notice a difference in pain relief. Thanks for the great information.
The legality of CBD in the US varies from state to state, but at the federal level, CBD is mysteriously classified as a Schedule I drug despite its sourcing. According to the federal government, Schedule I drugs are substances or chemicals with no currently accepted medical use and a high potential for abuse. Other Schedule I drugs include heroin, LSD, marijuana, and ecstasy. However, CBD can be purchased as a dietary supplement throughout the country despite the FDA’s official stance that CBD isn’t a supplement. The landscape of CBD legality in the US is exactly as confusing as it reads; that squirrely, perplexing itch at the back of your brain is cognitive dissonance, and it’s an entirely normal reaction.
Hemp is completely different from marijuana in its function, cultivation and application. But these differences didn’t stop our political leaders from getting confused and accidentally grouping all Cannabis species as a Schedule I Drug and banning it in 1970 under the Controlled Substances Act. Even after 45 years, the government still seems to have some confusion in distinguishing the two plants. Although legislation is being made, progress has been slow.In its application, hemp and marijuana serve completely different purposes. Marijuana, as it is widely known, is used for medicinal or recreational purposes. Hemp is used in variety of other applications that marijuana couldn’t possibly be used in. These include healthy dietary supplements, skin products, clothing, and accessories. Overall, hemp is known to have over 25,000 possible applications.

If your intention is to help treat chronic pain, then you may want to start out with a lower dose, and then proceed from there. If you notice effective results, you can downsize the dose, or likewise you can always up the dose until positive results are achieved. The key is to only increase your dosage in small increments so that you are able to pinpoint exactly how much CBD oil it takes to treat your condition. Be advised, though, that you should not exceed the recommended daily doses that are listed on the bottle and you should consult with a physician.
My mother has dementia/Alzheimers along with a broken knee that they will not repair do to her mental status. She is currently in a nursing home. I firmly believe her mental situation began with the over use of hydrocodone for over 30 years and was acerbated by the trauma of breaking and disconnecting her knee cap. Since weaning her off of her meds (still in progress) we have regained much of her consciousness. I want to try CBD to help in her recovery or to help slow down the disease. I cannot find a dosage recommendation plus the nursing home/doctor does not recommend it. I would need to give it to her when I am there visiting (about 3 - 4 times per week). Is there a recommended dosage for dementia/Alzheimers?
In 1976, Canadian botanist Ernest Small[66] and American taxonomist Arthur Cronquist published a taxonomic revision that recognizes a single species of Cannabis with two subspecies: C. sativa L. subsp. sativa, and C. sativa L. subsp. indica (Lam.) Small & Cronq.[62] The authors hypothesized that the two subspecies diverged primarily as a result of human selection; C. sativa subsp. sativa was presumably selected for traits that enhance fiber or seed production, whereas C. sativa subsp. indica was primarily selected for drug production. Within these two subspecies, Small and Cronquist described C. sativa L. subsp. sativa var. spontanea Vav. as a wild or escaped variety of low-intoxicant Cannabis, and C. sativa subsp. indica var. kafiristanica (Vav.) Small & Cronq. as a wild or escaped variety of the high-intoxicant type. This classification was based on several factors including interfertility, chromosome uniformity, chemotype, and numerical analysis of phenotypic characters.[52][62][67] 

Although cannabis as a drug and industrial hemp both derive from the species Cannabis sativa and contain the psychoactive component tetrahydrocannabinol (THC), they are distinct strains with unique phytochemical compositions and uses.[6] Hemp has lower concentrations of THC and higher concentrations of cannabidiol (CBD), which decreases or eliminates its psychoactive effects.[6] The legality of industrial hemp varies widely between countries. Some governments regulate the concentration of THC and permit only hemp that is bred with an especially low THC content.[7][8]
Health psychology, developed in the late 1970s, is its own domain of inquiry. A health psychologist, also called a medical psychologist, helps individuals explore the link between emotions and physical health. The health psychologist also helps physicians and medical professionals understand the emotional effects of a patient’s illness or disease. These experts practice in such areas of health as chronic pain management, oncology, physical rehabilitation, addiction treatment, and eating disorders, among others. Health psychologists can be found in clinics, hospitals, private practice, and public health agencies. Some also work in corporate settings to promote health and wellness among employees, engaging in workplace policies and decision-making.
As detailed below, the development of hemp as a new legal crop in North America must be considered in relation to illicit cultivation, so it is important to appreciate the scope of the drug situation. Up until the first half of the 20th century, drug preparations of Cannabis were used predominantly as a recreational inebriant in poor countries and the lower socio-economic classes of developed nations. After World War II, marijuana became associated with the rise of a hedonistic, psychedelic ethos, first in the United States and eventually over much of the world, with the consequent development of a huge international illicit market that exceeds the value of the hemp market during its heyday. Table 3 shows the “economic significance” (dollars generated in the black market plus dollar cost of control measures) of the illicit drug industry associated with C. sativa, and contrasts this with the estimated dollar value of major categories of legitimate uses. In the Netherlands, the annual value of narcotic hemp cultivation (ca. $10 billion) exceeds the value of tulips (Collins 1999). Marijuana has become the most widely disseminated illicit species in the world (Schultes and Hofmann 1980). With the exception of alcohol, it is the most widely used recreational euphoric drug. About 25% of North Americans are believed to have used Cannabis illegally. According to the US National Institute on Drug Abuse (www.nida.nih.gov/Infofax/marijuana.html), more than 72 million Americans (33%) 12 years of age and older have tried marijuana. Cultivation, commerce, and consumption of drug preparations of Cannabis have been proscribed in most countries during the present century. The cost of enforcing the laws against Cannabis in North America is in the billions of dollars annually. In addition, there are substantial social costs, such as adverse effects on users, particularly those who are convicted. Tragically this includes some legitimate farmers who, faced with financial ruin because of the unprofitability of crops being grown, converted to growing marijuana.
So-called “pure hybrids,” while oxymoronic in name, indicate marijuana strains that are believed to offer a perfect blend or balance of sativa’s energizing and indica’s sedating effects. Other hybrid strains of cannabis tend to place the emphasis on one end of the spectrum or the other. These are called “sativa-dominant” or “indica-dominant,” accordingly.

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.
Not until the end of the 20th century was the specific mechanism of action of THC at the neuronal level studied.[citation needed] Researchers have subsequently confirmed that THC exerts its most prominent effects via its actions on two types of cannabinoid receptors, the CB1 receptor and the CB2 receptor, both of which are G protein-coupled receptors.[142] The CB1 receptor is found primarily in the brain as well as in some peripheral tissues, and the CB2 receptor is found primarily in peripheral tissues, but is also expressed in neuroglial cells.[143] THC appears to alter mood and cognition through its agonist actions on the CB1 receptors, which inhibit a secondary messenger system (adenylate cyclase) in a dose-dependent manner. These actions can be blocked by the selective CB1 receptor antagonist rimonabant (SR141716), which has been shown in clinical trials to be an effective treatment for smoking cessation, weight loss, and as a means of controlling or reducing metabolic syndrome risk factors.[144] However, due to the dysphoric effect of CB1 receptor antagonists, this drug is often discontinued due to these side effects.[145]
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.
Even as the research proceeds, thousands of people are using CBD as medicine. A British pharmaceutical company, GW Pharma, has developed two CBD drugs: Sativex, which contains a 1-to-1 ratio of CBD and THC, and Epidiolex, which is pure CBD. The former is prescribed for the painful muscle spasms that occur in multiple sclerosis, while the latter is aimed at childhood seizures. Sativex is not available in the United States, but it is approved in 29 other countries, including Canada, England and Israel.
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.[54] 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."[55] 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.[55] Physiological barriers to reproduction are not known to occur within Cannabis, and plants from widely divergent sources are interfertile.[43] 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.[56] 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.[57][58][59]
CBD does not appear to have any psychotropic ("high") effects such as those caused by ∆9-THC in marijuana, but may have anti-anxiety and anti-psychotic effects.[10] As the legal landscape and understanding about the differences in medical cannabinoids unfolds, experts are working to distinguish "medical marijuana" (with varying degrees of psychotropic effects and deficits in executive function) – from "medical CBD therapies” which would commonly present as having a reduced or non-psychoactive side-effect profile.[10][59]
