Cannabidiol—more commonly abbreviated as CBD—isn’t psychoactive and, apparently to the man’s disappointment, won’t get you high. Instead, many people report that consuming it makes them feel less anxious, helps them sleep, or eases joint pain. Over the past two years, CBD in the form of oils and supplements has become widely distributed across the United States, even in places with no level of cannabis legalization. Now the trend’s new frontier is food. My first clue that it had hit some kind of critical mass was seeing a local restaurant put a sign out front announcing the debut of CBD empanadas. From design-oriented Instagram seltzer to your local pizza place, brands and restaurants want you to order some CBD and eat your feelings.
Hashish (also spelled hasheesh, hashisha, or simply hash) is a concentrated resin cake or ball produced from pressed kief, the detached trichomes and fine material that falls off cannabis flowers and leaves.[179] or from scraping the resin from the surface of the plants and rolling it into balls. It varies in color from black to golden brown depending upon purity and variety of cultivar it was obtained from.[180] It can be consumed orally or smoked, and is also vaporised, or 'vaped'.[181] The term "rosin hash" refers to a high quality solventless product obtained through heat and pressure.[182]
Cannabis consumers have long prized potency (a high THC content) as one of the main factors that makes a particular strain more desirable. Though traditional demand for THC has caused an oversaturation of high-potency products, many consumers are starting to prefer less intense products that are lower in THC and higher in the non-intoxicating compound called cannabidiol (CBD).

Despite some relatively tough talk from regulatory bodies, it can seem like they’re trying to close the barn door after the horse got out. CBD is already everywhere, and people are curious about it for reasons that seem to go far beyond trendiness, such as financial precariousness and health-care costs. “People are panicking and looking for things. They’re like, ‘What if I don’t have insurance because I get laid off? What can I replace my meds with?’” says Donahue, the Allure editor. CBD fits neatly with a growing distrust in technology and in the pharmaceutical industry, and America’s moderating view of cannabis means that many people see CBD as a safer alternative for anxiety or pain that’s worth trying.
Cannabis use has the hallmark pathologic features shared by all substance use disorders. Like other drugs of abuse, Cannabis causes compulsive drug-seeking behaviors, loss of self-control, withdrawal symptoms, and the propensity to relapse.57 Cannabis use disorder has been recognized as a bona fide disorder and has been included in the most recent version of the Diagnostic and Statistical Manual of Mental Disorders (fifth edition).58 Long-term clinical outcomes for Cannabis use disorder may be less severe than for other drugs of abuse but the addictive processes appears to be very similar. Animal models of addiction have clearly supported the notion that Cannabis has addictive properties.
However, because no tools existed for quality control, it was impossible to prepare a standardized medicine, so patients often received a dose that was either too low, having no effect, or too high, resulting in serious side effects. Moreover, Cannabis extract was not water-soluble and therefore could not be injected (in contrast to, e.g., the opiates), whereas oral administration was found to be unreliable because of its slow and erratic absorption. Because of such drawbacks, the medicinal use of Cannabis increasingly disappeared in the beginning of the twentieth century, and in 1937 Cannabis was removed from the US pharmacopoeia, a move that was followed by most other Western countries.27 Isolation and structure elucidation of the first pure active substances from Cannabis was not achieved until the 1960s.29
Hemp stalk is baled for transportation and long-term storage using traditional farming balers. Large round balers are best for hemp because they allow for more thorough drying as they don’t pack the hemp as tightly as square balers. Hemp should be stored in a dry environment in conditions intended to reduce as much absorbable air moisture as possible. It’s also important to check for wet patches during baling to further avoid mold.
I use cbd oil every day. I refuse to go without it. I have no arthritic pain at all anymore. I had a hip replacement 3 years ago. I am in need of the other one to be replaced. I was laying awake crying at night because of my hip pain. After I started using the oil my hip has quit aching. I sometimes forget I even have a problem with it or my arthritis. Had I known about the oil before I had my hip replaced I never would have had the surgery. I am pain free. I use hemp oil. There are 20 mg of cannabiniol in each 1 ml dose.
Protein. Hemp seeds contain 25%–30% protein, with a reasonably complete amino acid spectrum. About two thirds of hempseed protein is edestin. All eight amino acids essential in the human diet are present, as well as others. Although the protein content is smaller than that of soybean, it is much higher than in grains like wheat, rye, maize, oat, and barley. As noted above, the oilcake remaining after oil is expressed from the seeds is a very nutritious feed supplement for livestock, but it can also be used for production of a high-protein flour.
There are many ways to prepare cannabis for consumption. And while final marijuana products may come in many forms, each aims to provide rich concentrations of the terpenes, cannabinoids, and other desirable compounds the marijuana plant produces. From the simple process of drying and curing marijuana flowers, to the sophisticated chemistry of producing cannabis concentrates, here’s a guide to the most common forms of cannabis.
In the first decade of the 21st century, the conceptualization of health as an ability opened the door for self-assessments to become the main indicators to judge the performance of efforts aimed at improving human health.[16] It also created the opportunity for every person to feel healthy, even in the presence of multiple chronic diseases, or a terminal condition, and for the re-examination of determinants of health, away from the traditional approach that focuses on the reduction of the prevalence of diseases.[17]

CBD oil alleviates physical pain and anxiety – both of which can have a negative impact on sleep. Additionally, CBD oil can actually prolong sleep for some, leading to more rest from night to night. Most medical experts agree that marijuana is not particularly beneficial for individuals with medical conditions and/or mental health disorders, as the THC can increase their symptoms; this makes CBD oil a good alternative option for people with the following sleep disorders and medical conditions.
A limited number of studies have examined the effects of cannabis smoking on the respiratory system.[89] Chronic heavy marijuana smoking is associated with coughing, production of sputum, wheezing, and other symptoms of chronic bronchitis.[69] The available evidence does not support a causal relationship between cannabis use and chronic obstructive pulmonary disease.[90] Short-term use of cannabis is associated with bronchodilation.[91] Other side effects of cannabis use include cannabinoid hyperemesis syndrome.[92]
In a July 1998 study issued by the Center for Business and Economic Research at the University of Kentucky, researchers concluded that Kentucky hemp farmers could earn a net profit of $600 per acre for raising certified seeds, $320 net profit per acre for straw only or straw and grain production, and $220 net profit per acre for grain only production. The only crop found to be more profitable was tobacco.
The exploding recreational market for marijuana has rapidly popularized many methods of consuming cannabis that was decidedly part of the fringe just a few short years ago. Smoking marijuana remains the most widely embraced method, due to the greater accessibility of marijuana flower. But legal recreational cannabis is introducing many marijuana users to new forms of the drug, especially concentrates and edibles. Here’s a brief overview of the major methods for consuming marijuana. 

The pulp and paper industry based on wood has considered the use of hemp for pulp, but only on an experimental basis. Hemp’s long fibers could make paper more recyclable. Since virgin pulp is required for added strength in the recycling of paper, hemp pulp would allow for at least twice as many cycles as wood pulp. However, various analyses have concluded that the use of hemp for conventional paper pulp is not profitable (Fertig 1996).
In recent months, both cities and states have moved to control how CBD is sold. Maine and New York City have moved to crack down on edible products containing CBD. New York’s health department confirmed to the New York Times that it has started ordering restaurants to stop selling CBD-laced food because it has not been “deemed safe as a food additive.”
My Wife had Polio at age 5 and the lingering damage to the L leg and muscle drove her crazy. At age 21 she was using heavy doses of muscle relaxers and pain meds. Needed to bomb herself at night to get some sleep. A Post polio group in West Palm Beach told her about Marijuana and she got some from the Jamaican health aide that was her constant helper. After 5 months she quit all meds. All of them. Slowly came out of the drugged state the meds had caused from 15 years of use. We separated good friends and I know she has gone back to school and getting a degree. All from the help of a plant from Jamaica. I never understood the statement this plant has no viable medical value. Something smells in the politics of this prohibition. Shame.
"Similar language was contained in the enacted FY2016 Consolidated Appropriations Act, wherein Congress blocked DEA and other federal law enforcement authorities from interfering with state agencies, hemp growers, and agricultural research.47 In addition, USDA was also blocked from prohibiting the transportation, processing, sale, or use of industrial hemp that is grown or cultivated in accordance with the 2014 farm bill provision.48 Legislation debating the FY2017 budget also contained similar restrictions.49
The farm bill is a sprawling piece of legislation that sets U.S. government agricultural and food policy for the country and is renewed roughly every five years. This version of the bill places industrial hemp — which is defined as a cannabis plant with under 0.3% of tetrahydrocannabinol, or THC — under the supervision of the Agriculture Department and removes CBD from the purview of the Controlled Substances Act, which covers marijuana. The law also “explicitly” preserved the Food and Drug Administration’s authority to regulate products containing cannabis, or cannabis-derived compounds.

Medical marijuana refers to the use of the Cannabis plant as a physician-recommended herbal therapy as well as synthetic[191] THC and cannabinoids. So far, the medical use of cannabis is legal only in a limited number of territories, including Canada,[38] Belgium, Australia, the Netherlands, Spain, and many U.S. states. This usage generally requires a prescription, and distribution is usually done within a framework defined by local laws. There is evidence supporting the use of cannabis or its derivatives in the treatment of chemotherapy-induced nausea and vomiting, neuropathic pain, and multiple sclerosis. Lower levels of evidence support its use for AIDS wasting syndrome, epilepsy, rheumatoid arthritis, and glaucoma.[78]

Smoking marijuana is hands down the most widely used method of consuming cannabis. It’s also the simplest: a rolling paper and some dried marijuana flower are all you need. Other, more technological methods of smoking marijuana may be rising in popularity. But for many people, the social experience of passing weed around with some friends is what cannabis is all about.
First, you should not take anything without consulting your physician. While CBD oil is largely safe, a small number of people experience side effects and it could interact with medications you may already be taking like certain antidepressants and antibiotics. Do not be shy about discussing this option, the more open and honest you can be with your doctor, the more they can help you figure out the best path forward if you are considering using CBD oil for pain.
When I first learned about CBD oil, I'll admit I was a bit skeptical. My mind immediately turned to weed and the unnerving experiences I'd had with heightened anxiety in college. For me, a person who's already predisposed to overthinking, marijuana, no matter what the form, would typically put my mind into overdrive and result in a common yet dreaded side effect: paranoia.

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.[48] 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.[53][62] 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.[48][64]
Technically speaking, its THC—the cannabinoid that gets you high—which is illicit. When you take a drug test, the aim is to detect THC in your body, not “cannabis.” If you possessed weed without any THC in it, technically you wouldn’t be in violation of the law. Because “weed” without THC has a different name: hemp. And the rules governing hemp are quite different from the restrictions placed on cannabis.
"Cannabinoids have been found to have antioxidant properties, unrelated to NMDA receptor antagonism. This new found property makes cannabinoids useful in the treatment and prophylaxis of wide variety of oxidation associated diseases, such as ischemic, age-related, inflammatory and autoimmune diseases. The cannabinoids are found to have particular application as neuroprotectants, for example in limiting neurological damage following ischemic insults, such as stroke and trauma, or in the treatment of neurodegenerative diseases, such as Alzheimer's disease, Parkinson's disease and HIV dementia. 

"The term ‘“marihuana” means all parts of the plant Cannabis sativa L., whether growing or not; the seeds thereof; the resin extracted from any part of such plant; and every compound, manufacture, salt, derivative, mixture, or preparation of such plant, its seeds or resin. Such term does not include the mature stalks of such plant, fiber produced from such stalks, oil or cake made from the seeds of such plant, any other compound, manufacture, salt, derivative, mixture, or preparation of such mature stalks (except the resin extracted therefrom), fiber, oil, or cake, or the sterilized seed of such plant which is incapable of germination.140
Marijuana, also called pot, weed, ganja, mary jane, and a host of other nicknames, is made from the Cannabis plant, which has three species: Cannabis sativa; Cannabis indica and Cannabis ruderalis. The flowering plant, which can grow to 16 feet (5 meters) high, likely originated in the Central Asian steppe, near the Altai or Tian Shian Mountains, and was first cultivated in China and India, according to "Cannabis and Cannabinoids: Pharmacology, Toxicology and Therapeutic Potential," (Routledge, 2002).
Understanding CBD’s analgesic, or pain-relieving, interactions with the ECS can shed light on CBD’s other interactions and effects. Importantly, the ECS participates in our bodies’ pain processing, but when CBD is introduced to our ECS, it stops the body from absorbing a pain-regulating compound known as anandamide — one of our body’s’ own natural cannabinoid molecules. Inhibiting the absorption of this compound shunts excess quantities into the bloodstream that in turn reduces pain. One study has revealed that CBD targets alpha-3 (α3) glycine receptors to suppress chronic pain and inflammation associated with dysfunctional glycine receptors, which are an important target for pain processing in the spine. In both humans and animal models, CBD has been shown to have a variety of anti-inflammatory properties.
The Medical Marijuana Industry here has glommed on to the “Alternative” Medicine Industry models. I half expected the Dispensary employee to explain that because the Hemp Oil was in contact with CBD, it was the same thing. The Industry even has high quality magazines where they advertise and give advice, most contain a lot of pseudo science. The refer to Pharma Industry Studies as proof that CBD works.
Chronic pain: The body’s ECS plays a role in alleviating and managing pain, so CBD oil can work as a supplement for individuals with medical conditions that cause chronic pain, such as arthritis and multiple sclerosis. CBD oil also increases levels of adenosine in the brain; adenosine is a neurotransmitter that aids cardiovascular function and eases painful inflammation.
Cognitive effects of cannabis have been reviewed (Russo et al 2002; Fride and Russo 2006), but less study has occurred in therapeutic contexts. Effects of chronic heavy recreational cannabis usage on memory abate without sequelae after a few weeks of abstinence (Pope et al 2001). Studies of components of the Halstead-Reitan battery with Sativex in neuropathic pain with allodynia have revealed no changes vs placebo (Nurmikko et al 2007), and in central neuropathic pain in MS (Rog et al 2005), 4 of 5 tests showed no significant differences. While the Selective Reminding Test did not change significantly on Sativex, placebo patients displayed unexpected improvement.

I strongly agree they really are greedy and money hungry. Isn’t it always funny how the big ones fall sooner or later? The government can’t have everything, there are just some things that belong to the people. Medicine plants in general have been around since the start of creation, and it looks like we’re just finding out which ones they are. Our forefathers know which ones they were and they knew how to use them but it’s been a forgotten skill some generations have forgotten since modern medicine took over. That’s not right. I saw some articles where the government was going to try to once again outlaw hemp and cannabis. I say if you really want some before it’s outlawed, grab up as much as you can and hide it somewhere good where no one but you can ever find it. I would highly recommend putting it in an airtight container with as many other airtight layers around it as possible. That way, it will never be found by anyone who’s not supposed to find it. The best advantage is to have enough handy to take care of yourself for life while everyone not in on ditching big Pharma is dying. If hamper and cannabis are outlawed, only the elite will be the ones still standing in the end

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.
Jackson Leyden had always been a healthy kid; he practiced taekwondo, and he played lacrosse and baseball. But in 2011, a few months after his eighth birthday, he began having seizures several times a day. Many were brief, a half-minute of staring into space, but he also had severe episodes in which he would collapse, sometimes injuring himself. Over the next two years, he was hospitalized about 50 times, and he missed much of fourth and fifth grade.
The US Office of National Drug control Policy issued a statement on industrial hemp in 1997 (www.whitehousedrugpolicy.gov/policy/hemp%5Fold.html) which included the following: “Our primary concern about the legalization of the cultivation of industrial hemp (Cannabis sativa) is the message it would send to the public at large, especially to our youth at a time when adolescent drug use is rising rapidly... The second major concern is that legalizing hemp production may mean the de facto legalization of marijuana cultivation. Industrial hemp and marijuana are the product of the same plant, Cannabis sativa... Supporters of the hemp legalization effort claim hemp cultivation could be profitable for US farmers. However, according to the USDA and the US Department of Commerce, the profitability of industrial hemp is highly uncertain and probably unlikely. Hemp is a novelty product with limited sustainable development value even in a novelty market... For every proposed use of industrial hemp, there already exists an available product, or raw material, which is cheaper to manufacture and provides better market results.... Countries with low labor costs such as the Philippines and China have a competitive advantage over any US hemp producer.”
Cannabis use and psychotic symptoms and disorders are associated in the general population (see, for example, Degenhardt and Hall, 2001; Tien and Anthony, 1990) and in clinical samples of patients with schizophrenia (Mueser et al., 1992; Warner et al., 1994; Hambrecht and Hafner, 1996). The major contending hypotheses to explain the association have been: (i) that cannabis use precipitates schizophrenia in persons who are otherwise vulnerable; (ii) cannabis use is a form of self-medication for schizophrenia; and (iii) that the association arises from uncontrolled residual confounding by variables that predict an increased risk of cannabis use and of schizophrenia (Macleod et al., 2004).
Particular difficulties face the clinician managing intractable patients afflicted with cancer-associated pain, neuropathic pain, and central pain states (eg, pain associated with multiple sclerosis) that are often inadequately treated with available opiates, antidepressants and anticonvulsant drugs. Physicians are seeking new approaches to treatment of these conditions but many remain concerned about increasing governmental scrutiny of their prescribing practices (Fishman 2006), prescription drug abuse or diversion. The entry of cannabinoid medicines to the pharmacopoeia offers a novel approach to the issue of chronic pain management, offering new hope to many, but also stoking the flames of controversy among politicians and the public alike.
Hemp has been grown for millennia in Asia and the Middle East for its fibre. Commercial production of hemp in the West took off in the eighteenth century, but was grown in the sixteenth century in eastern England.[147] Because of colonial and naval expansion of the era, economies needed large quantities of hemp for rope and oakum. In the early 1940s, world production of hemp fiber ranged from 250 000 to 350 000 metric tonnes, Russia was the biggest producer.[132]
Marijuana, also called pot, weed, ganja, mary jane, and a host of other nicknames, is made from the Cannabis plant, which has three species: Cannabis sativa; Cannabis indica and Cannabis ruderalis. The flowering plant, which can grow to 16 feet (5 meters) high, likely originated in the Central Asian steppe, near the Altai or Tian Shian Mountains, and was first cultivated in China and India, according to "Cannabis and Cannabinoids: Pharmacology, Toxicology and Therapeutic Potential," (Routledge, 2002).
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.

Lisa Hamilton, a jeweler and doula in Brooklyn, NY, knows about the side effects. She recently tried CBD for the shoulder pain that plagued her five years after an accident. Her doctor certified that she was in chronic pain, which under New York State law allowed her to buy from a state dispensary. One Friday, she swallowed two 10-mg capsules, the amount recommended at the dispensary, then took another two on Saturday. “By Sunday, it felt like I’d gotten hit by a truck. Every muscle and joint ached,” Hamilton says. She cut back to one pill a day the following week, but still felt hungover. She stopped after that.
Unlike other CBD oils, PureKana really does excel in CBD oil extractions due to their unique CO2 extraction process which provides a near 99% pure CBD oil. PureKana Natural CBD Oil is an unflavored, dietary and nutritional supplement for increased health and vitality. It is extremely effective in treating chronic pain, inflammation, swelling, anxiety and sleep disorders.
In addition to providing useful fibers, hemp seed also has high nutritional value. and the plant can be used to make biodegradable plastics, some fuels, and a variety of other things. Hemp foods including but not limited to hemp energy bars, hemp salad dressing,hemp milk, hemp protein shakes, hemp oil gel caps and hemp protein powder are among some of the health products being produced today.

"Hemp oil is extremely nutritious, and is used in foods and nutraceutical products for humans and animals, as well as in personal care products. Hemp oil is also suitable for use in industrial products such as paints, varnishes, inks and industrial lubricants, and can be used to produce biodiesel. The crushed seed meal left over from oil production is frequently used for animal feed." 

Common adverse events (AE) of Sativex acutely in RCTs have included complaints of bad taste, oral stinging, dry mouth, dizziness, nausea or fatigue, but do not generally necessitate discontinuation, and prove less common over time. While there have been no head-to-head comparative RCTs of Sativex with other cannabinoid agents, certain contrasts can be drawn. Sativex (Rog et al 2005) and Marinol (Svendsen et al 2004) have both been examined in treatment of central neuropathic pain in MS, with comparable results (Table 1). However, adverse events were comparable or greater with Marinol than with Sativex employing THC dosages some 2.5 times higher due to the presence of accompanying CBD (Russo 2006b; Russo and Guy 2006).
Many monoecious varieties have also been described,[20] in which individual plants bear both male and female flowers.[21] (Although monoecious plants are often referred to as "hermaphrodites", true hermaphrodites – which are less common in Cannabis – bear staminate and pistillate structures together on individual flowers, whereas monoecious plants bear male and female flowers at different locations on the same plant.) Subdioecy (the occurrence of monoecious individuals and dioecious individuals within the same population) is widespread.[22][23][24] Many populations have been described as sexually labile.[25][26][27]
The reason so many people are interested in cannabis products that don’t make them high, proponents say, is that CBD helps with everything from pain and nausea to rheumatoid arthritis, cancer, Crohn’s disease, and dementia. CBD is anti-inflammatory, anti-anxiety, antibacterial, immunosuppressive, and more, says Joseph Cohen, D.O., a cannabis doctor in Boulder, CO.

“What we know is that THC and CBD combined has a greater therapeutic effect than either one given alone,” Lee continued. “The best medicines to use are the medicines that have both THC and CBD. What we suggest to people – and I will emphasize we are not doctors – is that people should use products that have as much THC as possible, with the CBD, that doesn’t make them feel dysphoric or stoned.”
CBD has some other very important jobs outside of the endocannabinoid system (ECS). For instance, CBD mildly activates one of the brain’s predominant serotonin receptors (5-HT1A), which may explain CBD’s effects on depression and anxiety. It also acts at the peroxisome proliferator activated receptors (PPARs), which halt the proliferation of cancer cells and convey neuro- and cardioprotection. By interacting with a particular PPAR (gamma), CBD could prove to be a promising new way to prevent alzheimer’s disease and other brain disorders.

Cannabis Ruderalis – Thought to be a cannabis species originating in central Asia, it flowers earlier, is much smaller, and can withstand much harsher climates than either Cannabis indica or Cannabis sativa. This species purportedly buds based on age rather than changes in length of daylight, known as auto-flowering. It’s used primarily for food production, such as hemp seeds and hemp seed oil.
The plant is also known as hemp, although this term is often used to refer only to varieties of Cannabis cultivated for non-drug use. Cannabis has long been used for hemp fibre, hemp seeds and their oils, hemp leaves for use as vegetables and as juice, medicinal purposes, and as a recreational drug. Industrial hemp products are made from cannabis plants selected to produce an abundance of fiber. To satisfy the UN Narcotics Convention, some cannabis strains have been bred to produce minimal levels of tetrahydrocannabinol (THC), the principal psychoactive constituent. Some strains have been selectively bred to produce a maximum of THC (a cannabinoid), the strength of which is enhanced by curing the flowers. Various compounds, including hashish and hash oil, are extracted from the plant.[8]
Success stories like Oliver’s are everywhere, but there’s not a lot of data to back up those results. That’s because CBD comes from cannabis and, like nearly all other parts of the plant, is categorized by the Drug Enforcement Agency (DEA) as a Schedule 1 drug—the most restrictive classification. (Others on that list: heroin, Ecstasy, and peyote.) This classification, which cannabis advocates have tried for years to change, keeps cannabis-derived products, including CBD, from being properly studied in the U.S.
In the 1970s, President Nixon declared a “War on Drugs” and signed into law the Controlled Substances Act of 1970. This law established a set of banned drugs and created the Drug Enforcement Administration (DEA). It also unintentionally outlawed one of the world’s oldest domesticated crop, hemp. This not only led to the demise of hemp, but also an increased misconception of the plant.
The question of whether heteromorphic sex chromosomes are indeed present is most conveniently answered if such chromosomes were clearly visible in a karyotype. Cannabis was one of the first plant species to be karyotyped; however, this was in a period when karyotype preparation was primitive by modern standards (see History of Cytogenetics). Heteromorphic sex chromosomes were reported to occur in staminate individuals of dioecious "Kentucky" hemp, but were not found in pistillate individuals of the same variety. Dioecious "Kentucky" hemp was assumed to use an XY mechanism. Heterosomes were not observed in analyzed individuals of monoecious "Kentucky" hemp, nor in an unidentified German cultivar. These varieties were assumed to have sex chromosome composition XX.[32] According to other researchers, no modern karyotype of Cannabis had been published as of 1996.[33] Proponents of the XY system state that Y chromosome is slightly larger than the X, but difficult to differentiate cytologically.[34]
Given the uncertainties and handicaps associated with hemp, it is fortunate that there are compensating factors. As noted, as a crop hemp offers some real environmental advantages, particularly with regard to the limited needs for herbicides and pesticides. Hemp is therefore pre-adapted to organic agriculture, and accordingly to the growing market for products associated with environmentally-friendly, sustainable production. Hemp products are an advertiser’s dream, lending themselves to hyperbole (“healthiest salad oil in the world,” “toughest jeans on the market”). While the narcotics image of C. sativa is often disadvantageous, advertisers who choose to play up this association do so knowing that it will attract a segment of the consuming population. In general, the novelty of hemp means that many consumers are willing to pay a premium price. It might also be said that those who have entered the hemp industry have tended to be very highly motivated, resourceful, and industrious, qualities that have been needed in the face of rather formidable obstacles to progress.
Cannabis is the most widely used illicit drug. Over 100 phytocannabinoids, as well as terpenoids, fatty acids, and other compounds with health relevance, have been found in Cannabis. The pharmacological importance of cannabinoids has been intensively studied. Multiple mechanisms of the effects of cannabinoids on the nervous system are being elucidated. Cannabinoids have anti-inflammatory, antioxidant, immunomodulatory, antimicrobial, and anticancer activities. Hemp seed oil and terpenoids have health-promoting effects. The relationship between Cannabis chemotype and genotype is being revealed by chemical and genetic analyses. Various omics platform facilitate the basic and applied studies of Cannabis plants. An expanded Cannabaceae family, which consists of six genera, is advocated. This chapter summarizes the recent research progress of phytochemistry, pharmacology, and omics of Cannabis plants.

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. 

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 Marinol patient monograph cautions that patients should not drive, operate machinery or engage in hazardous activities until accustomed to the drug’s effects (http://www.solvaypharmaceuticals-us.com/static/wma/pdf/1/3/1/9/Marinol5000124ERev52003.pdf). The Sativex product monograph in Canada (http://www.bayerhealth.ca/display.cfm?Object_ID=272&Article_ID=121&expandMenu_ID=53&prevSubItem=5_52) suggests that patients taking it should not drive automobiles. Given that THC is the most active component affecting such abilities, and the low serum levels produced in Sativex therapy (vide supra), it would be logical that that patients may be able to safely engage in such activities after early dose titration and according to individual circumstances, much as suggested for oral dronabinol. This is particularly the case in view of a report by an expert panel (Grotenhermen et al 2005) that comprehensively analyzed cannabinoids and driving. It suggested scientific standards such as roadside sobriety tests, and THC serum levels of 7–10 ng/mL or less, as reasonable approaches to determine relative impairment. No studies have demonstrated significant problems in relation to cannabis affecting driving skills at plasma levels below 5 ng/mL of THC. Prior studies document that 4 rapid oromucosal sprays of Sativex (greater than the average single dose employed in therapy) produced serum levels well below this threshold (Russo 2006b). Sativex is now well established as a cannabinoid agent with minimal psychotropic effect.

Although marijuana smoke contains a number of carcinogens findings from a limited number of well-designed studies do not suggest an increased risk for the development of either lung or upper airway cancer from light or moderate use. However, the evidence is mixed when it comes to the carcinogenic risks of heavy, long-term marijuana users, according to this study.

Cannabidiol (CBD) oil is used by some people with chronic pain. CBD oil may reduce pain, inflammation, and overall discomfort related to a variety of health conditions. CBD oil is a product made from cannabis. It’s a type of cannabinoid, a chemical found naturally in marijuana and hemp plants. It doesn’t cause the “high” feeling often associated with cannabis, which is caused by a different type of cannabinoid called THC.

Despite the fact that Cannabis was grown on a large scale in many countries, the abuse as a narcotic remained uncommon in Western countries until relatively recently. People were largely unaware of the psychoactive properties of Cannabis and it is unlikely that early cultivars, selected mainly for their seed or fiber qualities, contained significant amounts of the psychoactive THC. The medicinal use of Cannabis was introduced in Europe only around 1840, by a young Irish doctor, William O’Shaughnessy, who served for the East India Trading Company in India, where the medicinal use of Cannabis was widespread. Unlike the European fiber Cannabis, these Indian varieties did contain a reasonable amount of bioactive cannabinoids. In the following decades, the medicinal use of Cannabis saw a short period of popularity both in Europe and in the United States. At the top of its popularity, more than 28 different medicinal preparations were available with Cannabis as active ingredient, which were recommended for indications as various as menstrual cramps, asthma, cough, insomnia, support of birth labor, migraine, throat infection, and withdrawal from opium use.27


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]

Did you get an answer for this? I have the exact same scenario. I'm treating my TN with Tegretol, and recently tried CBD. I think I took too much and there are some weird drug interactions with Tegretol and I felt quite stoned....was alone and talking to myself in my head thinking I was Einstein. It freaked me out a bit but I think I took too much. I'm trying lower doses again as recently my TN seems to be resisting the meds, although I have had a lot of emotional stress, which seems to be a trigger. Thanks!! Anna
Cannabis has long had an image problem, because of the extremely widespread use of “narcotic” cultivars as illegal intoxicants. The US Drug Enforcement Administration has the mandate of eliminating illicit and wild marijuana, which it does very well (Fig. 54–56). Those interested in establishing and developing legitimate industries based on fiber and oilseed applications have had to struggle against considerable opposition from many in the political and law enforcement arenas. The United States National Institute on Drug Abuse (NIDA) information web site on marijuana, which reflects a negative view of cannabis, is at www.nida.nih.gov/DrugPages/Marijuana.html, and reflects several basic fears: (1) growing Cannabis plants makes law enforcement more difficult, because of the need to ensure that all plants cultivated are legitimate; (2) utilization of legitimate Cannabis products makes it much more difficult to maintain the image of the illegitimate products as dangerous; (3) many in the movements backing development of hemp are doing so as a subterfuge to promote legalization of recreational use of marijuana; and (4) THC (and perhaps other constituents) in Cannabis are so harmful that their presence in any amount in any material (food, medicine or even fiber product) represents a health hazard that is best dealt with by a total proscription.
The psychoactive effects of cannabis are known to have a triphasic nature. Primary psychoactive effects include a state of relaxation, and to a lesser degree, euphoria from its main psychoactive compound, tetrahydrocannabinol. Secondary psychoactive effects, such as a facility for philosophical thinking, introspection and metacognition have been reported among cases of anxiety and paranoia.[94] Finally, the tertiary psychoactive effects of the drug cannabis, can include an increase in heart rate and hunger, believed to be caused by 11-OH-THC, a psychoactive metabolite of THC produced in the liver.

Senate Majority Leader Mitch McConnell continues to be ardently anti-marijuana, despite the success of these programs and the fact that 62% of Americans say recreational marijuana should be legal. Nevertheless, McConnell and Senate Republicans read the political tea leaves and will now recognize the important differences between marijuana and hemp. In doing so, they’re creating an exciting time for entrepreneurs, CBD advocates, and farmers across the country.
The Drug Enforcement Agency and the Office of National Drug Control Policy of the US raised concerns over tests conducted from 1995 to 1997 that showed that consumption of hempseed products available during that period led to interference with drug-testing programs for marijuana use. Federal US programs utilize a THC metabolite level of 50 parts per billion in urine. Leson (2000) found that this level was not exceeded by consuming hemp products, provided that THC levels are maintained below 5 ppm in hemp oil, and below 2 ppm in hulled seeds. Nevertheless the presence of even minute trace amounts of THC in foods remains a tool that can be used by those wishing to prevent the hemp oilseed industry from developing.

Cannabis is a flowering plant used for both recreational and medicinal purposes. Three main types (species, subspecies, or varieties) of the cannabis genus have been recognized: Cannabis sativa, Cannabis indica, and Cannabis ruderalis. Δ(9)-Tetrahydrocannabinol is the main psychoactive/addictive ingredient of cannabis; the effects of this compound are most commonly associated with binding to the cannabinoid receptor 1 (Hoffman & Lupica, 2013).


The plant is also known as hemp, although this term is often used to refer only to varieties of Cannabis cultivated for non-drug use. Cannabis has long been used for hemp fibre, hemp seeds and their oils, hemp leaves for use as vegetables and as juice, medicinal purposes, and as a recreational drug. Industrial hemp products are made from cannabis plants selected to produce an abundance of fiber. To satisfy the UN Narcotics Convention, some cannabis strains have been bred to produce minimal levels of tetrahydrocannabinol (THC), the principal psychoactive constituent. Some strains have been selectively bred to produce a maximum of THC (a cannabinoid), the strength of which is enhanced by curing the flowers. Various compounds, including hashish and hash oil, are extracted from the plant.[8]
Years passed, and more studies rolled out with medically beneficial findings regarding cannabis until 2009 when Steep Hill Laboratory in Oakland, California, tested cannabis samples provided by Harborside Health Center to discover that a handful of cultivars contained more CBD than THC. This discovery kicked other labs into gear. They wanted to study medical cannabis to understand and potentially calibrate their cannabinoid ratios. Soon thereafter, laboratories uncovered CBD-dominant strains boasting 20:1 CBD to THC ratios, which opened up the cannabis market for a panoply of CBD products.
Fatty acids and GLA may also help curb the physical and emotional pain linked to PMS. Here's why: One of the causes of PMS is a hormonal imbalance that leads to a lack of GLA in the body. Research on GLA has shown to help alleviate the symptoms of PMS by bringing hormone levels back into balance. But so far, studies haven't found ingesting or slathering on hemp oil itself will have this effect.
This is not stated to discourage the use of the product because I have read…..some patients have had some efffective relief wth CBD oil but, pain managment is subjective to each individual patient even with opioid medicatios, Research, asking questions is important and the representatives of CBD oil product providers are more than willing to talk to you. There are different ways that the product is extracted from the plant. One in particular seems quite dangerous to me. Read for yourself. Again I do not discourage trying the product. Some, a great deal of patients are even reporting effective pain management with other products such as “kratom”. Again this product is not FDA approved and has no quality control regulation. Word of mouth amd sometimes great reviews but, again pain is subjective to each patient.
But even though it's infiltrating pretty much every corner of the wellness world (hi, vegan CBD brownies!) many people still find CBD a little confusing—especially when it comes to figuring out the right way to use it and how to make sure the stuff you're buying is, you know, actually legit. Below, we asked experts to answer the most pressing questions about CBD.
"Similar language was contained in the enacted FY2016 Consolidated Appropriations Act, wherein Congress blocked DEA and other federal law enforcement authorities from interfering with state agencies, hemp growers, and agricultural research.47 In addition, USDA was also blocked from prohibiting the transportation, processing, sale, or use of industrial hemp that is grown or cultivated in accordance with the 2014 farm bill provision.48 Legislation debating the FY2017 budget also contained similar restrictions.49
The US Office of National Drug control Policy issued a statement on industrial hemp in 1997 (www.whitehousedrugpolicy.gov/policy/hemp%5Fold.html) which included the following: “Our primary concern about the legalization of the cultivation of industrial hemp (Cannabis sativa) is the message it would send to the public at large, especially to our youth at a time when adolescent drug use is rising rapidly... The second major concern is that legalizing hemp production may mean the de facto legalization of marijuana cultivation. Industrial hemp and marijuana are the product of the same plant, Cannabis sativa... Supporters of the hemp legalization effort claim hemp cultivation could be profitable for US farmers. However, according to the USDA and the US Department of Commerce, the profitability of industrial hemp is highly uncertain and probably unlikely. Hemp is a novelty product with limited sustainable development value even in a novelty market... For every proposed use of industrial hemp, there already exists an available product, or raw material, which is cheaper to manufacture and provides better market results.... Countries with low labor costs such as the Philippines and China have a competitive advantage over any US hemp producer.”

In September 2005, New Scientist reported that researchers at the Canberra Institute of Technology had identified a new type of Cannabis based on analysis of mitochondrial and chloroplast DNA.[81] The New Scientist story, which was picked up by many news agencies and web sites, indicated that the research was to be published in the journal Forensic Science International.[82]


One of the most curious uses of hemp is as a fence to prevent pollen transfer in commercial production of seeds. Isolation distances for ensuring that seeds produced are pure are considerable for many plants, and often impractical. At one point in the 1980s, the only permitted use of hemp in Germany was as a fence or hedge to prevent plots of beets being used for seed production from being contaminated by pollen from ruderal beets. The high and rather inpenetrable hedge that hemp can produce was considered unsurpassed by any other species for the purpose. As well, the sticky leaves of hemp were thought to trap pollen. However, Saeglitz et al. (2000) demonstrated that the spread of beet pollen is not effectively prevented by hemp hedges. Fiber (i.e. tall) cultivars of hemp were also once used in Europe as wind-breaks, protecting vulnerable crops against wind damage. Although hemp plants can lodge, on the whole very tall hemp is remarkably resistant against wind. 

In a Phase II double-blind, randomized, placebo-controlled, 5-week study of 56 rheumatoid arthritis patients with Sativex (Blake et al 2006), employed nocturnal treatment only to a maximum of 6 sprays per evening (16.2 mg THC + 15 mg CBD). In the final treatment week, morning pain on movement, morning pain at rest, DAS-28 measure of disease activity, and SF-MPQ pain at present all favored Sativex over placebo (Table 1).
Following an 1836–1840 travel in North Africa and the Middle East, French physician Jacques-Joseph Moreau wrote on the psychological effects of cannabis use; he was a member of Paris' Club des Hashischins.[citation needed] In 1842, Irish physician William Brooke O'Shaughnessy, who had studied the drug while working as a medical officer in Bengal with the East India company, brought a quantity of cannabis with him on his return to Britain, provoking renewed interest in the West.[205] Examples of classic literature of the period featuring cannabis include Les paradis artificiels (1860) by Charles Baudelaire and The Hasheesh Eater (1857) by Fitz Hugh Ludlow.
I have idiopathic peripheral neuropathy ... the only thing they found that would work is lyrica. I picked up some CBD oil yesterday morning. I am prescribed to take 75 mg of lyrica 3x per day. I took one yesterday morning and have only used the CBD oil since. I bought the Koi brand, flavored, 250 MG. I used a full dropper yesterday late morning and a full dropper yesterday late afternoon. I used it once today (one full dropper) and I am amazingly pain free.

There has been little high-quality research into the use of cannabidiol for epilepsy, and what there is is limited to refractory epilepsy in children.[16] While the results of using medical-grade cannabidiol in combination with conventional medication shows some promise, they did not lead to seizures being eliminated, and were associated with some minor adverse effects.[16]


Donald Abrams was a member of the committee that reviewed the evidence that went into producing the report, and he said that the studies they reviewed overwhelmingly used pharmaceutically available preparations that contain THC, including dronabinol, nabilone and the whole-plant extract spray nabiximols, which contains equal parts CBD and THC. It’s impossible to know whether the benefits of cannabis can also be obtained from CBD alone, Abrams said, because CBD is just one of 400 chemicals present in the plant. So far, CBD in isolation has been studied in only a handful of randomized, placebo-controlled trials (considered the gold standard of evidence in medical research), and the evidence remains sparse.

I assume this is also a side effect of the eased anxiety, but I seem to fall asleep within the 20- to 30-minute range rather than my normal 45 minutes to one hour (or longer). Not only do I seem to be skipping (or at least shortening) the whole tossing-and-turning phase of my sleep cycle, but I'm able to snap out of the overthinking mindset that often keeps me up at night. Of course, there's no telling whether a big life event would kindly disrupt this newfound bliss, but I'd like to think it's helped on day-to-day basis.

The earliest recorded uses date from the 3rd millennium BC.[32] 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.[33][34] 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.[35][36] In September 2018, cannabis was legalized in South Africa[37] while Canada legalized recreational use of cannabis in October 2018.[38]
Zammit and colleagues (2002) reported a 27-year follow-up of the Swedish cohort study. This study improved on the earlier study in the following ways: the psychiatric register provided more complete coverage of cases diagnosed with schizophrenia; and there was better statistical control of more potentially confounding variables, including other drug use, IQ, known risk factors for schizophrenia and social integration. Cannabis use at baseline predicted a dose–response relationship between the frequency of cannabis use at age 18 and the risk of schizophrenia during the follow-up. The relationship persisted after statistically controlling for the effects of other drug use and other potential confounding factors, including a history of psychiatric symptoms at baseline. They estimated that 13 percent of cases of schizophrenia could be averted if all cannabis use were prevented.

Hemp has very low levels of another cannabis compound, tetrahydrocannabinol (THC) — the main psychoactive compound in marijuana. Evidence suggests that THC — not CBD — causes the symptoms people associate with getting high on marijuana, Blessing says. Unlike marijuana, which the CDC argues is addictive, CBD also doesn’t seem to be, according to the World Health Organization.

I use cbd oil every day. I refuse to go without it. I have no arthritic pain at all anymore. I had a hip replacement 3 years ago. I am in need of the other one to be replaced. I was laying awake crying at night because of my hip pain. After I started using the oil my hip has quit aching. I sometimes forget I even have a problem with it or my arthritis. Had I known about the oil before I had my hip replaced I never would have had the surgery. I am pain free. I use hemp oil. There are 20 mg of cannabiniol in each 1 ml dose. 

The problem is, it’s not easy to know what you’re actually ingesting, or if it’ll actually change how you feel. At best, CBD in America exists in a confusing state of quasi-legality and yet-to-be-realized potential. Experts estimate that the market for it could balloon to $22 billion by 2022, but with cannabis and hemp laws changing rapidly across the country, the chemical is almost entirely unregulated on the consumer market, with no end-product labeling or composition standards to help shoppers understand what they’re buying.
The Spaniards brought hemp to the Americas and cultivated it in Chile starting about 1545.[117] Similar attempts were made in Peru, Colombia, and Mexico, but only in Chile did the crop find success.[118] In July 1605, Samuel Champlain reported the use of grass and hemp clothing by the (Wampanoag) people of Cape Cod and the (Nauset) people of Plymouth Bay told him they harvested hemp in their region where it grew wild to a height of 4 to 5 ft. [119] In May 1607, "hempe" was among the crops Gabriel Archer observed being cultivated by the natives at the main Powhatan village, where Richmond, Virginia is now situated;[120] and in 1613, Samuell Argall reported wild hemp "better than that in England" growing along the shores of the upper Potomac. As early as 1619, the first Virginia House of Burgesses passed an Act requiring all planters in Virginia to sow "both English and Indian" hemp on their plantations.[121] The Puritans are first known to have cultivated hemp in New England in 1645.[117]
Cannabinoid agonists produce many effects beyond those mediated directly on receptors, including anti-inflammatory effects and interactions with various other neurotransmitter systems (previously reviewed (Russo 2006a). Briefly stated, THC effects in serotonergic systems are widespread, including its ability to decrease 5-hydroxytryptamine (5-HT) release from platelets (Volfe et al 1985), increase its cerebral production and decrease synaptosomal uptake (Spadone 1991). THC may affect many mechanisms of the trigeminovascular system in migraine (Akerman et al 2003; Akerman et al 2004; Akerman et al 2007; Russo 1998; Russo 2001). Dopaminergic blocking actions of THC (Müller-Vahl et al 1999) may also contribute to analgesic benefits.
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.
