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]
Some states only allow for products infused with CBD, some only allow for high-CBD and low-THC products, while others allow both THC and CBD. To further confuse the American citizenry, some states permit patients the use of CBD, but require that they travel to another state to purchase it. To make sense of this confounding patchwork and to learn about each individual state’s CBD laws, read the Weedmaps Laws and Regulations page.
A. The Agriculture Improvement Act of 2018 changes certain federal authorities relating to the production and marketing of hemp, defined as cannabis (Cannabis sativa L.), and derivatives of cannabis with extremely low (less than 0.3 percent on a dry weight basis) concentrations of the psychoactive compound delta-9-tetrahydrocannabinol (THC). These changes include removing hemp from the Controlled Substances Act, which means that it will no longer be an illegal substance under federal law. However, Congress explicitly preserved the agency's current authority to regulate products containing cannabis or cannabis-derived compounds under the FD&C Act and section 351 of the Public Health Service Act. Please see the FDA’s statement on the signing of the Agriculture Improvement Act of 2018.
While CBD can be extracted from non-hemp varieties of the plant, hemp-derived CBD is less restricted by the government because of its inherently low levels of THC. CBD from hemp is legal for sale in most US states, while CBD products derived from non-hemp varieties can contain noticeable amounts of THC, and are therefore subject to stricter laws and regulations.
It’s also important to select CBD oil products based on your concentration preferences. Some forms of CBD oil – such as vapors and tinctures – normally have higher-than-average concentrations, whereas sprays and topicals tend to have lower concentrations. Remember: higher concentration means more pronounced effects, but not necessarily mean higher quality.
Given the opioid crisis, physicians are less likely to lead with narcotics, and some of us are deciding not to prescribe them altogether. The problem with narcotics is that they work. They work really well. Sometimes too well, leading to a patient becoming so comfortable they “forget” to breathe. So, while reducing the amount of narcotics prescribed to patients is a good thing, the problem is physicians don’t have a lot of good alternatives to recommend to their patients, until now.
In order to manage pain, we recommend ingesting full spectrum CBD oil daily in the form of Tinctures or Gel Capsules. The ingredients in the two products are the same; the only difference between the two is the form factor and dosage – pills vs. sublingual tinctures. We suggest those suffering from any kind of pain start with 5-10mg per day of CBD. If relief is not felt at this dosage, we suggest increasing by 5-10mg until the desired effects are achieved. You’ll notice that the Gel Capsules are pre-filled and contain 25mg of CBD per pill – there is no harm in starting at 25mg CBD daily as you cannot overdose on CBD nor are there any serious side effects. These ingestible products provide sustained relief for several hours – many people find they provide relief for the whole day! The one thing to keep in mind with ingestible CBD products is the delayed onset time – it can take up to 90 minutes for the full effects of the tinctures or capsules to be felt.
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.[178] 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.[179] It can be consumed orally or smoked, and is also vaporised, or 'vaped'.[180] The term "rosin hash" refers to a high quality solventless product obtained through heat and pressure.[181]

Extensive studies have demonstrated that many common illnesses are related to deficiencies or imbalances of specific fatty acids in the body. Symptoms are often related to a lack of Omega 3 and Omega 6 fatty acids and their derivatives, the postaglandins. Most people eating a healthful diet, one that includes a balanced ratio of essential fatty acids, also have healthy skin and a strong immune system. Yet some individuals may experience shortages in specific fatty acids or their metabolites due to dysfunctional enzyme systems or other inhibitions in their metabolic pathways caused by genetic, immune-system-related, or even environmental factors. It has been proven in several clinical studies that dietary supplementation with essential fatty acids or their metabolites (such as GLA) will often prevent or even cure these illnesses. Since hemp seed oil contains both essential fatty acids in a desirable balance while also providing two of the essential fatty acid metabolites, it is a good resource for the prevention and treatment of certain illnesses. 

If CBD is derived from Marijuana, it is illegal in many areas as are all constituents of the plant. When derived from commercial hemp, CBD is legal as the Cannabinoids contained in non-psychoactive strains of Cannabis are exempt from regulation in the US and around 40 other countries when used in Hemp finishing products. Current legal status of Cannabidiol can been seen on the wiki page here.
Sublingual CBD Oils – also known as CBD Tinctures or CBD Hemp Oil – are the most popular type of CBD products, because of their high bioavailability and rapid absorption. There are many other kinds of products as well, including CBD edibles, CBD topicals, and even CBD-infused Coffee. CBD products have gained immense popularity in health and wellness circles thanks to their natural support of our endocannabinoid system (ECS).

If you live in a state where cannabis is illegal, you might have a difficult time acquiring legitimate CBD oil in a retail location. Most people turn to the Internet in an effort to buy CBD online, and typically find a range of stores all claiming to sell the best stuff and ship it right to your house. The problem is that there are no testing regulations of these products, so the effectiveness and safety of many of these products has not been proven. Therefore, the onus falls on the manufacturer to be honest about how much CBD is actually in the oil, where the starting material was grown and how it's been extracted. The FDA actually issued a warning for making false claims of effectiveness and medicinal benefits because so many illegitimate companies sell snake oil marketed as CBD that doesn't do anything (here's how to avoid that). Despite all these challenges, if you know what you're buying, hemp-derived CBD oil as a product itself is not illegal.
The extract known as CBD oil sold in the U.S. falls into one of two categories. Crystalline isolate exclusively contains CBD, as other cannabinoids have been removed; full spectrum oil, on the other hand, retains THC and other cannabinoids, and is only sold in states where marijuana use has been legalized. CBD oil can be consumed several different ways, including ingested capsules and food products, vaporizing, tinctures, and topical creams. The soporific effects of CBD oil are linked to its concentration; low-concentration oils will produce minimal effects, while high-concentration oils will produce strong effects.
CBD is a 5-HT1A receptor agonist, which may also contribute to an anxiolytic effect.[155] This likely means the high concentrations of CBD found in Cannabis indica mitigate the anxiogenic effect of THC significantly.[155] The cannabis industry claims that sativa strains provide a more stimulating psychoactive high while indica strains are more sedating with a body high.[156] However this is disputed by researchers.[157]
The company reported a 282% increase in quarterly revenue as marijuana became legal in Canada, but earnings were slammed by paper losses and accounting quirks that may be unfamiliar to U.S. investors. Canadian companies use a different accounting standard to GAAP, or Generally Accepted Accounting Principles, the one U.S. companies are required to follow.
As the PeaceHealth website suggests, hemp oil derives from a plant that contains high levels of the neurological chemical THC. This chemical can cause hallucinations, euphoria or high anxiety in supplement users when taken on a regular basis. As such, hemp oil supplements can cause similar effects in some patients using the herb for the treatment of any disorder. It is recommended that supplement users not take hemp oil products prior to operating machinery or driving due to the risk of these hallucinogenic properties. This is especially true to individuals who are overly-sensitive to THC, which can be determined by visiting your medical doctor for more information.
However, the DEA has recently made many people nervous by talking about CBD restrictions. So how can people know if the CBD they acquire is legal? They simply have to check the source, and it’s clear sailing from there on out. For example, Medix CBD has CBD products that are legal across all fifty states, meaning that their products are always safe to use.

Molecular analytical techniques developed in the late 20th century are being applied to questions of taxonomic classification. This has resulted in many reclassifications based on evolutionary systematics. Several studies of Random Amplified Polymorphic DNA (RAPD) and other types of genetic markers have been conducted on drug and fiber strains of Cannabis, primarily for plant breeding and forensic purposes.[74][75][25][76][77] Dutch Cannabis researcher E.P.M. de Meijer and coworkers described some of their RAPD studies as showing an "extremely high" degree of genetic polymorphism between and within populations, suggesting a high degree of potential variation for selection, even in heavily selected hemp cultivars.[37] They also commented that these analyses confirm the continuity of the Cannabis gene pool throughout the studied accessions, and provide further confirmation that the genus consists of a single species, although theirs was not a systematic study per se.


This does nothing for me. I have been taking between 4 and 8 Aleeve a day for back pain related to kyphosis and hoped this would help me cut down on those medications. This is hemp oil, not CBD oil. After trying this and receiving no results I switched to CBD oil from a well reviewed company and the CBD oil is helping. I now take the CBD oil twice a day and have noticeable results. I have cut my regular pain meds to one or two a day.

Cannabis flavonoids in whole cannabis extracts may also contribute useful activity (McPartland and Russo 2001). Apigenin inhibits TNF-α (Gerritsen et al 1995), a mechanism germane to multiple sclerosis and rheumatoid arthritis. Cannflavin A, a flavone unique to cannabis, inhibits PGE-2 thirty times more potently than aspirin (Barrett et al 1986), but has not been subsequently investigated.

James Joliat, a 35-year-old video producer in Denver, has long experienced muscle and joint pain—mostly related to sports injuries. He says he started looking at natural remedies as an alternative to the prescription patches and pills his doctor recommended. After experimenting with homemade rubs infused with plant compounds—stuff like arnica and turmeric—he eventually stumbled onto topical cannabidiol (CBD) rubs.
Cannabidiol has been found to act as an antagonist of GPR55, a G protein-coupled receptor and putative cannabinoid receptor that is expressed in the caudate nucleus and putamen in the brain.[32] It has also been found to act as an inverse agonist of GPR3, GPR6, and GPR12.[13] Although currently classified as orphan receptors, these receptors are most closely related phylogenetically to the cannabinoid receptors.[13] In addition to orphan receptors, CBD has been shown to act as a serotonin 5-HT1A receptor partial agonist,[33] and this action may be involved in its antidepressant,[34][35] anxiolytic,[35][36] and neuroprotective effects.[37][38] It is an allosteric modulator of the μ- and δ-opioid receptors as well.[39] The pharmacological effects of CBD have additionally been attributed to PPARγ agonism and intracellular calcium release.[7]
Another concern is about medications with which CBD might interact. This won’t be an issue with most drugs, says Sunil Kumar Aggarwal, M.D., Ph.D., a palliative medicine physician and scientist who studies cannabis and integrates it into his Seattle medical practice. The exceptions are blood thinners, IV antibiotics, and other drugs whose exact dosing is crucial and must be monitored closely, he says. (Of course, if you have a health problem, talk to your doctor before using CBD, and never take it instead of seeing your physician for a serious condition.) 

Down to its versatility and myriad of health benefits, Hemp Oil has reached an all time high in popularity, and men are women who want to make healthier lifestyle choices are reaching for the wellbeing product. Hemp is an all natural ingredient which can support your health and well-being through a high supply of minerals, antioxidants and amino acids. If you’re living in the UK its completely legal to find, purchase and consume this oil, it is however the availability and legality of hemp oil in the US is complex and confusing due to the the complex relationship between state and federal legislations.

Cannabinoids may offer significant “side benefits” beyond analgesia. These include anti-emetic effects, well established with THC, but additionally demonstrated for CBD (Pertwee 2005), the ability of THC and CBD to produce apoptosis in malignant cells and inhibit cancer-induced angiogenesis (Kogan 2005; Ligresti et al 2006), as well as the neuroprotective antioxidant properties of the two substances (Hampson et al 1998), and improvements in symptomatic insomnia (Russo et al 2007).
Cannabis is known to aid relaxation, which makes it a popular treatment for social anxiety – however due to the THC content in cannabis, it can actually trigger more intense feelings of paranoia and anxiety. CBD on the other hand, has the opposite effect, helping to calm down the nerves and keep you grounded. Anxiety disorders and other feelings of irrational fear can be overwhelming especially if you find yourself in unfamiliar environments, however CBD can be used effectively to generate calmness and peacefulness, and without the addictive component of anti-anxiety medication like Benzos or Xanax.
Depression? Arthritis? Inflammation contributes to pain, stiffness, and poor health over time. Many individuals opt for CBD to control inflammation. However, THC has a part to play as well. Research suggests that, in some instances, the cannabis compound can decrease the production of cytokine and chemokine compounds in the body. Cytokine and chemokines are immune compounds that trigger inflammation. Additional pre-clinical research suggests that it may be able to decrease inflammation by suppressing genes related to inflammatory response. I believe people deserve access to all parts of the cannabis plant! Together, we can spread the cannabis education not DEA lies! Just as they have done opiates! Also, it’s ridiculous to wage war between the two! Have pain patients saying medical marijuana doesn’t work etc and others saying opiates are bad. There should be access to both – whatever works for someone! I never used marijuana until forced off my opiates cold turkey in cancer recurrence left dying in stage 4 cancer pain! It stopped the pain, vomiting & 2 metastatic tumors gone confirmed via MRI. I’m not claiming it cured it but feel it slowed it down and did kill two tumors. Marijuana/Opiates – WE SHOULD HAVE A CHOICE OR BOTH IF NEEDED! Shame on our Government for all the lies and trying to turn the people against one another. I hate the DEA, CDC, FDA! Just alone at what they allow in our food – the steroids, antibiotics it is sickening! They take away opiates yet cigarettes & alcohol are legal!?!?! What kind of [edit] is that! And marijuana has never caused one death – sch 1. The alcohol/cigarette related addictions/deaths as well as cases of cancer as other terminal illness they cause! Hell we need opiates for the pain from those illnesses from their legal substances they avoid talking about if I keep it real because they sure as hell wont!
To decide between these hypotheses, we need evidence that cannabis use preceded the psychosis; that plausible alternative explanations based on confounding can be excluded (Hall, 1987). The best evidence for answering these questions comes from longitudinal population-based studies that have assessed cannabis use before the onset of psychotic symptoms, followed the cohort over a substantial period and used statistical methods to assess the contribution of a variety of factors other than cannabis use that may explain the relationship (Macleod et al., 2004).
The use of Cannabis as a mind-altering drug has been documented by archaeological finds in prehistoric societies in Eurasia and Africa.[85] The oldest written record of cannabis usage is the Greek historian Herodotus's reference to the central Eurasian Scythians taking cannabis steam baths.[86] His (c. 440 BCE) Histories records, "The Scythians, as I said, take some of this hemp-seed [presumably, flowers], and, creeping under the felt coverings, throw it upon the red-hot stones; immediately it smokes, and gives out such a vapour as no Grecian vapour-bath can exceed; the Scyths, delighted, shout for joy."[87] Classical Greeks and Romans were using cannabis, while in the Middle East, use spread throughout the Islamic empire to North Africa. In 1545, cannabis spread to the western hemisphere where Spaniards imported it to Chile for its use as fiber. In North America, cannabis, in the form of hemp, was grown for use in rope, clothing and paper.[88][89][90][91]
Hempseed oil is manufactured from varieties of Cannabis sativa that do not contain significant amounts of tetrahydrocannabinol (THC), the psychoactive element present in the cannabis plant. This manufacturing process typically includes cleaning the seed to 99.99% before pressing the oil. There is no THC within the hempseed, although trace amounts of THC may be found in hempseed oil when plant matter adheres to the seed surface during manufacturing. The modern production of hempseed oil, particularly in Canada, has successfully lowered THC values since 1998.[5] Regular accredited sampling of THC in Canadian hemp seed oil shows THC levels usually below detection limit of 4 ppm (parts per million, or 4 mg/kg). Legal limit for THC content in foodstuffs in Canada is 10 ppm.[6] Some European countries have limits of 5 ppm or none-detected, some EU countries do not have such limits at all.
Ironically, the only four states where you can be absolutely sure that the CBD content claimed on the label is the CBD content in the bottle are Colorado, Washington, Oregon, and Alaska, where adult-use cannabis is legal and regulated. That’s because the CBD products available in licensed retail cannabis stores must pass state-mandated lab tests to assure their purity and potency. In fact, if these products haven’t gone through state testing, they’re liable to be seized, as happened recently in Alaska.
“THC”—the more-famous, high-inducing compound in cannabis—“works directly on the cannabinoid system, meaning it attaches to receptors and mimics some of our own internal endocannabinoids,” says Igor Grant, a professor and chair of psychiatry at the University of California, San Diego School of Medicine. But CBD’s interaction with the endocannabinoid system is subtler. “Normally, these endocannabinoid-signaling molecules are broken down by enzymes, and one thing CBD does is interfere with the actions of those enzymes.”
Go natural with CBD! This has become one of the biggest health trends as of late, and for good reason. CBD is a natural compound that has a multitude of health benefits. And unlike THC, this cannabis compound is non-psychoactive. It is perfectly legal, safe to use, and effective on a variety of levels. Whether you are trying to reduce pain from an injury or nurse inflammation from sickness or aging, CBD Pain Cream is your ticket to a pain-free life!  † And now you can try it first before buying.

Think of the primary difference between hemp oil and CBD oil in the same way that coffee beans differ from pure caffeine extract. Hemp oil includes over 100 cannabinoids that are found throughout the hemp plant—cannabidiol is just one of these. When you purchase pure CBD oil, you are purchasing an isolated compound that is derived from hemp oil. We have a whole post dedicated to the characteristics of this particular compound available for you to read more.

PTSD. My husband suffers chronic PTSD from active military service. We live not far from a large Army base and though my husband served with another counties military we hear stories constantly of family breakdowns over PTSD. It’s not a easy path but I’m hoping one day to find something to stop the endless trips to the psych ward. It’s just not right that those who serve come home to no government help.
You are likely very familiar with the dangers that prescription painkillers (and other pharmaceuticals) present. In fact, it’s estimated that the majority of CBD oil users attempt to switch to the all-natural therapy for the precise reason of kicking prescription med habits, which all too often cause an overwhelming array of irritability, sleep disruption, digestive complications, and even thoughts of suicide.
