The leaves have a peculiar and diagnostic venation pattern that enables persons poorly familiar with the plant to distinguish a cannabis leaf from unrelated species that have confusingly similar leaves (see illustration). As is common in serrated leaves, each serration has a central vein extending to its tip. However, the serration vein originates from lower down the central vein of the leaflet, typically opposite to the position of, not the first notch down, but the next notch. This means that on its way from the midrib of the leaflet to the point of the serration, the vein serving the tip of the serration passes close by the intervening notch. Sometimes the vein will actually pass tangent to the notch, but often it will pass by at a small distance, and when that happens a spur vein (occasionally a pair of such spur veins) branches off and joins the leaf margin at the deepest point of the notch. This venation pattern varies slightly among varieties, but in general it enables one to tell Cannabis leaves from superficially similar leaves without difficulty and without special equipment. Tiny samples of Cannabis plants also can be identified with precision by microscopic examination of leaf cells and similar features, but that requires special expertise and equipment.
Grant says this may lead to a “dampening” or mellowing of some neurochemical processes, including those linked to pain. “CBD may also react with other receptors, like those for serotonin, and it may have actions that reduce the inflammatory molecules produced whenever there is tissue damage or bacteria coming in,” he says. “But we really don’t know the mechanisms.”
A limited number of studies have examined the effects of cannabis smoking on the respiratory system. Chronic heavy marijuana smoking is associated with coughing, production of sputum, wheezing, and other symptoms of chronic bronchitis. The available evidence does not support a causal relationship between cannabis use and chronic obstructive pulmonary disease. Short-term use of cannabis is associated with bronchodilation. Other side effects of cannabis use include cannabinoid hyperemesis syndrome.

Cannabis most likely originates from Central Asia, as archeological evidence indicates that it was already cultivated in China for food and fiber 10 000 years ago. Even in ancient Egyptian mummies, clues have been found for the use of Cannabis as food or medicine.25 In fact, Cannabis is one of the oldest known medicinal plants and is described in almost every ancient handbook on plant medicine, most commonly in the form of a tincture or a tea.26,27 Some religions were closely related with the properties of the Cannabis plant. For example, in Hindu legend, Cannabis is believed to be the favorite food of the god Shiva, because of its energizing properties. As Cannabis spread from Asia toward the West, almost every culture came into contact with this miracle plant. Nowadays, varieties of Cannabis can be found in all temperate and tropical zones, except in humid, tropical rain forests.28

So is CBD legal? If we’re talking about hemp-derived CBD, then the answer is yes. Now, the keyword here is “hemp-derived.” Because CBD from hemp has no psychoactive effects, the purchase, sales, or possession of hemp CBD products are completely legal in all 50 States. Because hemp is sometimes confused with the marijuana plant, there is still some stigma towards hemp-derived CBD, but from a legal perspective, hemp-derived CBD is completely legal and enjoys the rights of any other legal product.
CBD e-liquids are made for vaporizers or electronic cigarettes. Usually, hemp extract or pure CBD is mixed with a classic e-liquid base called PG/VG. The e-liquids are then inserted into a cartridge or atomizer for an electronic cigarette. You may see the CBD vape oil used interchangeably with CBD e-liquids, so keep that in mind and don’t vape your regular CBD-rich oil unless you want a not so enjoyable experience.
I have spent the last year + researching over 200 CBD companies and their products. I learned how the CBD is extracted, the difference between IH (Industrial Hemp) and THC producing cannabis that is harvested early, so that is is given the legal term Hemp, but technically it is the marijuana plant, etc. First, I chose not to take CBD orally, because of how the body breaks down CBD, when you digest it, it goes through the liver first, meaning less than 20% of what you take ends up in your body. Very expensive!! With vaping CBD oil about 70% makes it right into your bloodstream. With the CBD wax/shatter/dab, it is the same. So I stopped the oral route altogether. If you would oral or vape (inhaling vapor, no combustion), you want to look to see or email the company to ask how they extract the CND, and ask if they use CBD frown in the US. I highly suggest CBD frown in the US! The old law had people growing it overseas, and shipping it here to be extracted. Make sure no solvents were used to extract the CBD, like Butane. Whatever they tell you about how they extract it, look it up! This is a MUST! The most common ways to extract are via CO2 extraction using cold temperatures sometimes called subcritical or supercritical temperatures, same with ethanol extraction, there is no solvent in that either. Please research online both methods. There are a couple of other methods, one comes to mind, but it does not stay fresh long, and I cannot recall the name, I have not found any products which use that method, which is why I cannot name it. After making sure it is not done with anything dangerous, you want to make sure they have batch lab reports that check for heavy metals, mold, and how much CBD,CBG,CBC, etc is in the product. CBD, Cannabidiol is the most common Cannabinoid found in the marijuana or hemp plant. Did you know that IH contains a very small amount of THC? it is at or under.3%, so it is low, but it does help the CBD work.
Refined hempseed oil is clear and colorless, with little flavor and lacks natural vitamins and antioxidants. Refined hempseed oil is primarily used in body care products. Industrial hempseed oil is used in lubricants, paints, inks, fuel, and plastics. Hempseed oil is used in the production of soaps, shampoos and detergents. The oil has a 3:1 ratio of omega-6 to omega-3 essential fatty acids. It may also be used as a feedstock for the large-scale production of biodiesel.
In some areas where cannabis use had been historically tolerated, new restrictions were instituted, such as the closing of cannabis coffee shops near the borders of the Netherlands, and closing of coffee shops near secondary schools in the Netherlands. In Copenhagen, Denmark in 2014, mayor Frank Jensen discussed possibilities for the city to legalize cannabis production and commerce.
Of course, because legal marijuana is in such a confusing transitional period, even here there are potential exceptions. The U.S. Food and Drug Administration (FDA) approved Epidiolex, a treatment for a rare form of pediatric epilepsy that contains CBD. The DEA decided to classify this as a Schedule 5 drug, the scheduling that indicates the lowest potential for addiction and abuse.
Recently, researchers have been testing different ways to attract marijuana users to treatment and help them abstain from drug use. There are currently no medications for treating marijuana dependence. Treatment programs focus on counseling and group support systems. Drug treatment researchers are learning which characteristics of users are predictors of treatment success and which approaches to treatment can be most helpful.
CBD modulates/diminishes the effects of THC so is not a desired trait for recreational strains of cannabis for the most part, unless in very small concentrations. Strains that approach a 1:1 ratio of THC to CBD have little psychoactive effect and are more suitable for medicinal use where high THC doses can be uncomfortable for some. It is only with the recent surge of interest in Cannabidiol that breeders are getting the financial incentive to work with these previously abandoned hemp strains in order to bring CBD back into the Cannabis genetic pool and develope strains such as Charlotte's Web, Cannatonic, ACDC and Harlequin, among many other high CBD variants, some of which now have low enough THC levels to qualify for industrial Hemp status. A great breakdown of some of the most well known High CBD strains being used to make Marijuana oil and extracts in Medical Marijuana states today may be found here via Synergy Wellness's site.
In 1988, the first cannabinoid receptor was identified (CB1) (Howlett et al 1988) and in 1993, a second was described (CB2) (Munro et al 1993). Both are 7-domain G-protein coupled receptors affecting cyclic-AMP, but CB1 is more pervasive throughout the body, with particular predilection to nociceptive areas of the central nervous system and spinal cord (Herkenham et al 1990; Hohmann et al 1999), as well as the peripheral nervous system (Fox et al 2001; Dogrul et al 2003) wherein synergy of activity between peripheral and central cannabinoid receptor function has been demonstrated (Dogrul et al 2003). CB2, while commonly reported as confined to lymphoid and immune tissues, is also proving to be an important mediator for suppressing both pain and inflammatory processes (Mackie 2006). Following the description of cannabinoid receptors, endogenous ligands for these were discovered: anandamide (arachidonylethanolamide, AEA) in 1992 in porcine brain (Devane et al 1992), and 2-arachidonylglycerol (2-AG) in 1995 in canine gut tissue (Mechoulam et al 1995) (Figure 1). These endocannabinoids both act as retrograde messengers on G-protein coupled receptors, are synthesized on demand, and are especially active on glutamatergic and GABA-ergic synapses. Together, the cannabinoid receptors, their endogenous ligands (“endocannabinoids”) and metabolizing enzymes comprise the endocannabinoid system (ECS) (Di Marzo et al 1998), whose functions have been prosaically termed to be “relax, eat, sleep, forget and protect” (p. 528). The endocannabinoid system parallels and interacts at many points with the other major endogenous pain control systems: endorphin/enkephalin, vanilloid/transient receptor potential (TRPV), and inflammatory. Interestingly, our first knowledge of each pain system has derived from investigation of natural origin analgesic plants, respectively: cannabis (Cannabis sativa, C. indica) (THC, CBD and others), opium poppy (Papaver somniferun) (morphine, codeine), chile peppers (eg, Capsicum annuum, C. frutescens, C. chinense) (capsaicin) and willow bark (Salix spp.) (salicylic acid, leading to acetylsalicylic acid, or aspirin). Interestingly, THC along with AEA and 2-AG, are all partial agonists at the CB1 receptor. Notably, no endocannabinoid has ever been administered to humans, possibly due to issues of patentability and lack of commercial feasibility (Raphael Mechoulam, pers comm 2007). For an excellent comprehensive review of the endocannabinoid system, see Pacher et al (2006), while Walker and Huang have provided a key review of antinociceptive effects of cannabinoids in models of acute and persistent pain (Walker and Huang 2002).
In general, the majority of people end up using higher-strength products for pain than they would for things like anxiety, stress, or depression. The majority of today’s best CBD oil manufacturers offer tinctures in three different “potencies,” usually in 100, 300, or 600 mg options. Many people start on a middle ground with a 300 mg option, and work your way up from there, but it is extremely important to consult with the brand you are purchasing from before consumption.
The use of Cannabis as a mind-altering drug has been documented by archaeological finds in prehistoric societies in Eurasia and Africa. The oldest written record of cannabis usage is the Greek historian Herodotus's reference to the central Eurasian Scythians taking cannabis steam baths. 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." 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.
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.
I like this product. At first I didn't like it because of the Stevia. That is the reason for the four stars instead of five. But with that said , I like the product . I find it taste great and it is relaxing and helps with my anxiety and depression . I also mix it with some other CBD things and this helps to make everything last longer . 5000 mg is a big plus too . So many others are 750 or 1000 and once you get above that , the price increases dramatically . This price is good for this product. I find that if I just take the CBD oil I have without this product that the effect is not good . My mother said it helps her with the arthritis pains and she also gave a little to her dog and she felt it helped him too . Great product and I will be ordering more.
If you live with chronic pain, you may have experienced how it can disrupt sleep and, in some cases, can contribute to anxiety and depression. Natural therapies, including exercising and taking up mind-body practices like meditation and yoga, and following an anti-inflammatory diet may help improve quality of life for some people who experience pain regularly.
Results of a Phase III study (N = 177) comparing Sativex, THC-predominant extract and placebo in intractable pain due to cancer unresponsive to opiates (Johnson and Potts 2005) demonstrated that Sativex produced highly statistically significant improvements in analgesia (Table 1), while the THC-predominant extract failed to produce statistical demarcation from placebo, suggesting the presence of CBD in the Sativex preparation was crucial to attain significant pain relief.
Cannabidiol can be taken into the body in multiple different ways, including by inhalation of cannabis smoke or vapor, as an aerosol spray into the cheek, and by mouth. It may be supplied as CBD oil containing only CBD as the active ingredient (no added tetrahydrocannabinol [THC] or terpenes), a full-plant CBD-dominant hemp extract oil, capsules, dried cannabis, or as a prescription liquid solution. CBD does not have the same psychoactivity as THC, and may affect the actions of THC. Although in vitro studies indicate CBD may interact with different biological targets, including cannabinoid receptors and other neurotransmitter receptors,as of 2018 the mechanism of action for its biological effects has not been determined.
“Simply put, cannabidiol is a schedule 1 controlled substance because marijuana is a schedule 1 controlled substance. Although it is a relatively new phenomenon, after thoroughly tracking the language of the Indiana law defining ‘marijuana’ it is evident that cannabidiol is now and historically has been derived from ‘a part of the plant genus cannabis.'”
In contrast, THC did not tamp down levels of these inflammation-related molecules, called prostaglandins. “These prostaglandins are involved in many processes (such as) memory loss, neuroinflammation, hair loss and vasoconstriction,” he says. That means PET is “highly interesting for medicinal applications, as we can expect fewer adverse effects while still having pharmacologically important effects.” The reduced potency of PET also might put a damper on any interest in the liverwort for recreational use, especially in an era of increasingly loosened cannabis regulation.
In recent years however, with increasing state legalization of cannabis and a burgeoning multibillion-dollar cannabis industry, US farmers have increasingly lobbied to remove federal restrictions against growing hemp. The Agricultural Act of 2014 (aka the 2014 Farm Bill) signed by President Obama set the stage for this to happen by loosened restrictions on hemp, allowing universities and state agriculture departments to grow it for research purposes. Now the 2018 Farm Bill opens those gates more broadly, allowing licensed farmers to grow hemp and transport it across state lines based on agreements and regulations to be established between states and the federal government.
I know choosing the right product is a bit tricky as you have hemp oil or CBD oil (containing real CBD) and you have Hempseed oil which might still be very rich in goodness but contain about zero CBD. It means it has a very different effect. I learned the hard way when I received the bottle. It says you have more than 200 mg hempseed oil per serving... while product with CBD would tell you the actual dose per serving which is around 16-20mg... so I am not arguing about the quality of the product just saying I was buying CBD to calm joint pains and I end up with a product rich in Omega’s but with zero CBD. Needless to say that I have tried but got zero result. Missleading in my opinion
Karl W. Hillig, a graduate student in the laboratory of long-time Cannabis researcher Paul G. Mahlberg 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. 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. 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. 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. 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.
Hemp oil can be used for the treatment of minor health ailments and as a dietary supplement for the promotion of general good health. Hemp oil is considered one of the most useful natural supplements for the body due to its ability to provide essential fatty acids to humans that we would not be able to manufacture on our own. However, you should also be aware of potential side effects associated with hemp oil. As such, be sure to speak to a medical professional for more information on hemp oil effects.
There are also other difficulties in researching the effects of cannabis. Many people who smoke cannabis also smoke tobacco. This causes confounding factors, where questions arise as to whether the tobacco, the cannabis, or both that have caused a cancer. Another difficulty researchers have is in recruiting people who smoke cannabis into studies. Because cannabis is an illegal drug in many countries, people may be reluctant to take part in research, and if they do agree to take part, they may not say how much cannabis they actually smoke.
CBD oil is extracted from the industrial hemp plant, Cannabis Sativa. The seeds of the hemp plant are pressed until the oils are released. This is what makes cannabidiol different from and less psychoactive than THC, which is extracted from the marijuana plant, Cannabis Indica. The industrial hemp oil has traces of THC in it, about 3% in potency, not sufficient in causing a ‘high’. Despite its non-addictive nature, CBD oil may require a medical prescription for legal acquisition in some provinces.
While the other CBD oil stores have high-quality products, our choice simply came down to variety, potency and price. Whichever you choose to go for, though, know that all of the companies above have an outstanding store and offer a wide range of effective products, from CBD oils to Terps and even CBD creams. Plus, most have a 100% money back guarantee policy, which is quite nice!
So instead, go with an American company who has built up a good reputation of selling high-quality products. Every Day Optimal is by far one of the best in the business right now. They have amazing purification processes that take their quality to the next level. Furthermore, they only use medicinal hemp, which is the best grade possible! Their company has developed a unique structure which allows them to carry out quality checks at any given time. The CBD products they sell are also 100% legal to use.
