Keep in mind that CBD levels may vary from crop to crop—even from plant to plant. However, below are some strains that have been bred to contain higher CBD levels, so they might be a good place to start. Check the map on their strain page to see if these are sold at a dispensary near you. We also recommend checking with dispensaries about the specifics of their strains’ CBD levels. It’s always a good idea to purchase only lab-tested products that clearly state the CBD/THC levels so you know what kind of experience to expect.


CBD oil products can be somewhat expensive, which may be a barrier for individuals seeking treatment or relief from different conditions and disorders. cbdMD is a notable exception as far as price-point is concerned. cbdMD offers it’s premium, non-THC oils at a large variety of concentrations (300mg-5,000mg) as well as sizes (30mL and 60mL) . These oils are priced at $29.99 for 300mg oils and $99.99 for 1,500mg oils; these price-points are significantly below average.
ECS is made up of endocannabinoids and the receptors associated with them. These receptors are literally found from head to toe, and are in such places as the glands, organs, and the brain. While receptors and endocannabinoids are located in all parts of the body, they have different functions depending upon where they are located, with the primary role being to regulate what is referred to as homeostasis or the regulation of the body so that it is at equilibrium.
Fig. 5. Typical architecture of categories of cultivated Cannabis sativa. Top left: narcotic plants are generally low, highly branched, and grown well-spaced. Top right: plants grown for oilseed were traditionally well-spaced, and the plants developed medium height and strong branching. Bottom left: fiber cultivars are grown at high density, and are unbranched and very tall. Bottom center: “dual purpose” plants are grown at moderate density, tend to be slightly branched and of medium to tall height. Bottom right: some recent oilseed cultivars are grown at moderate density and are short and relatively unbranched. Degree of branching and height are determined both by the density of the plants and their genetic background.
Unfortunately due to strict FDA regulations I am unable to make claims on our products based on your specific needs, I can however say that CBD is a natural anti-inflammatory and could assist. I can also share our top selling products in each category.

During the period from 1937 to the late 60s, the U.S. government understood and acknowledged that industrial hemp and marijuana were distinct varieties of the Cannabis plant. Hemp was no longer officially recognized as distinct from marijuana after the passage of the Controlled Substances Act (CSA) of 1970. This is despite the fact that a specific exemption for hemp was included in the CSA under the definition of marijuana. The recent federal court case HIA vs DEA has re-established acknowledgement of distinct varieties of Cannabis, and supports the exemption for non-viable seed and fiber and any products made from them.

Berenson looks, too, at the early results from the state of Washington, which, in 2014, became the first U.S. jurisdiction to legalize recreational marijuana. Between 2013 and 2017, the state’s aggravated-assault rate rose seventeen per cent, which was nearly twice the increase seen nationwide, and the murder rate rose forty-four per cent, which was more than twice the increase nationwide. We don’t know that an increase in cannabis use was responsible for that surge in violence. Berenson, though, finds it strange that, at a time when Washington may have exposed its population to higher levels of what is widely assumed to be a calming substance, its citizens began turning on one another with increased aggression.
I was in awe of CBD's potent effects, especially when I learned that the oil could be used to treat everyday ailments like anxiety, chronic pain, migraines, nausea, and inflammation in addition to serious issues like epilepsy, cancer, multiple sclerosis, and Parkinson's. With that, I threw caution to the wind and asked for a sample. Here's what happened when I took one full dropper of Charlotte's Web's Everyday Plus Hemp Oil in the mint chocolate flavor every morning for seven days.
A rather thorough analysis of the scope of the illicit marijuana industry in Canada for 1998 is reported at www.rcmp-grc.gc.ca/html/drugsituation.htm#Marihuana and summarized in MacLeod (1999). At least 800 tonnes (t) of marijuana were grown in Canada in 1998, representing a harvest of 4.7 million flowering plants. More than 50% of the marijuana available in Canada is grown domestically. An average mature plant was estimated to produce 170 g of “marketable substance.” The value of the Canadian crop is uncertain, but has been estimated to be in the billions of dollars annually (Heading 1998; MacLeod 1999).

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.”


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.
The confusion compounds when one realizes that in today’s popular lexicon, the terms indica, sativa, and hybrid tend to indicate a set of effects, rather than the taxonomy of a particular strain. But that’s just as well. Most marijuana strains today, especially those under commercial cultivation, are genetic hybrids. Only a handful of pure, or “landrace” cannabis strains are in circulation.
Hello. I have stage 4 thyroid, secondary lymphoma..And many other health issues.I use 50mg of cbd vapor oil. 5 drops with each use. Total equals 250mg, about hits per dose, three times a day. I'm also on subsys, which is fentanyl. Idk about anyone but myself, but it's helped me with pain, with sleep, and in general my moods. So I dint have anything negative to say. I just hope that with time, proper diet, low dose chemo, and some other herbal usage, that I can shirk some of the cancer eating at my body... Thanks and good luck to you all.
Everything you need to know about marijuana (cannabis) Marijuana, or cannabis, is the most commonly used illicit drug in the world. It alters the mood and affects nearly every organ in the body. With at least 120 active compounds, marijuana may have health benefits as well as risks. We describe these, addiction, and withdrawal. Learn more about cannabis here. Read now
Also high in fiber, hemp seeds are more digestible than any other high-protein food, including meat, cheese, eggs, human milk, or cows’ milk. They’re high in antioxidants, and minerals like iron, zinc and copper as well as calcium, magnesium, potassium, carotene, thiamin (vitamin B1), riboflavin (vitamin B2), vitamin B6 and vitamin E. If that’s not enough, there’s also chlorophyll, sulfur, phosphorus, phospholipids, and phytosterols.
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.

Sometimes, products that claim to contain CBD don’t have any at all when tested, Blessing says. More commonly, though, cookies and beverages simply contain far less than 300 milligrams of CBD, which is the minimum amount she says has been found effective in the preliminary science so far. Vybes, a brand of CBD-laced drinks, has 15 milligrams of the compound in each bottle. Feelz by Chloe, a line of CBD desserts from the vegan fast-casual chain By Chloe, has said in the past that each dessert contains only 2.5 milligrams of CBD a serving.
Buying CBD oil online is problematical. A study from the University of Pennsylvania published in 2017 found that nearly 70 percent of products sold online do not contain the concentration of the oil listed on the label. The researchers bought and analyzed 84 products from 31 different companies and found that more than 42 percent were under-labeled, meaning that they contained more CBD than indicated. Another 26 percent were over-labeled, with less CBD than indicated. The researchers wrote that while studies haven’t shown that too much CBD can be harmful, products containing too much or too little may not give purchasers the effects they seek. In addition, the team reported that a number of products analyzed contained a significant amount of THC, which can cause undesired effects.
Opiates are another common pain solution and, unfortunately, they also present a significant number of problems. Opiate medications can be effective at reducing pain symptoms but they are often incredibly strong, causing sedation and a lack of functioning when trying to perform daily activities. A tolerance to opiates can develop over time which means higher and higher doses are required to achieve the same results. Opiates are also very habit forming. It is easy to misuse and overdose on opiates which is one of the reasons that North America is currently in the grip of an opioid crisis, with more than 115 people dying from opiate overdose in the United States every single day.

In the mid 1990s, the EU provided subsidization for hemp cultivation of ca. $1,050/ha. This support was instrumental in developing a hemp industry in western Europe. However, no comparable support is available in North America, and indeed those contemplating entering into hemp cultivation are faced with extraordinary costs and/or requirements in connection with licensing, security, THC analysis, and record keeping. Those involved in value-added processing and distribution are also faced with legal uncertainties and the regular threat of idiosyncratic, indeed irrational actions of various governments. Simply displaying a C. sativa leaf on advertising has led to the threat of criminal charges in the last decade in several G8 countries. Attempting to export or import hemp products among countries is presently a most uncertain activity.

While there are more unknowns than knowns at this point, Grant says he doesn’t discount all the anecdotal CBD reports. “You hear somebody say, ‘Hey, I gave this to myself and my kid and we feel a lot better,’ and we should never dismiss that kind of information,” he says. He points out that many modern medicines were discovered when researchers followed up on exactly this sort of human trial-and-error evidence. “But we still need to do the studies that confirm whether all the good things are true, and how much to give, and how to give it,” he says. “These are all questions that need to be answered.”
I’ve done a little research on the hemp and cannabis, and it looks to me like they’re both supposed to be medicine plants. From what I learned about the plants, they’ve been known to actually have multiple health benefits and even save lives of fourth stage cancer patients, sending the cancer into remission and therefore saving the patient lives. Banning this medicine plant has actually caused the deaths of many people who could have otherwise been saved by this plant. No wonder people are getting it other ways, I don’t blame them as long as it’s strictly for medical purposes. I even heard of a case where one child’s seizures were so bad they had to end up moving to Colorado as a last resort to save that little girl’s life by giving her cannabis because no other medicine worked for her.

Whether that $3 will get you anything is a more complicated question. Esther Blessing, a researcher and psychiatry professor at New York University Langone Health, is one of only a few researchers who have completed a review of CBD’s effects on mood. She looked at its potential to treat anxiety, and although she stresses the results are very preliminary, she sees a lot of promise. “Studies so far have shown that CBD of a specific dose is roughly as effective as drugs like Valium and other benzodiazepines in reducing experimental anxiety,” she says.


I work well under pressure, but being extremely busy at work has almost made me less productive—I'm constantly distracted by email, Slack, and the people around me, to the point where getting my work done becomes difficult. This week, however, I've found it easier to put my blinders on, block out all distractions (especially social distractions) and focus on one task at a time. I think this is partly related to the lessened anxiety—I feel more frazzled and off task when my anxiety is running high. It almost feels like a newfound sense of clarity and calm that enables me to focus.

The legality of CBD in the US varies from state to state, but at the federal level, CBD is mysteriously classified as a Schedule I drug despite its sourcing. According to the federal government, Schedule I drugs are substances or chemicals with no currently accepted medical use and a high potential for abuse. Other Schedule I drugs include heroin, LSD, marijuana, and ecstasy. However, CBD can be purchased as a dietary supplement throughout the country despite the FDA’s official stance that CBD isn’t a supplement. The landscape of CBD legality in the US is exactly as confusing as it reads; that squirrely, perplexing itch at the back of your brain is cognitive dissonance, and it’s an entirely normal reaction.


Hemp is considered by a 1998 study in Environmental Economics to be environmentally friendly due to a decrease of land use and other environmental impacts, indicating a possible decrease of ecological footprint in a US context compared to typical benchmarks.[63] A 2010 study, however, that compared the production of paper specifically from hemp and eucalyptus concluded that "industrial hemp presents higher environmental impacts than eucalyptus paper"; however, the article also highlights that "there is scope for improving industrial hemp paper production".[64] Hemp is also claimed to require few pesticides and no herbicides, and it has been called a carbon negative raw material.[65][66] Results indicate that high yield of hemp may require high total nutrient levels (field plus fertilizer nutrients) similar to a high yielding wheat crop.[67]

Even if you live in a state where recreational marijuana is legal, the mainstream sale of CBD in bakeries and coffee shops is still a whole different issue, according to Griffen Thorne, a California-based attorney with Harris Bricken, a firm specializing in cannabis-trade issues. For cannabis, “one of the things that’s a really big requirement in California is safety testing at the distributor level,” Thorne says. “That’s not really there yet for hemp CBD products.” For instance, CBD products sometimes contain enough lingering THC to produce psychoactive effects.

Just read your article about CBD oil and checked the label on the oil I bought 9 months ago from a legal dispensary in Pendleton, Oregon. Across from the Subway. It lists herbs and supplements long before CBD oil and it is a derivative of Hemp oil. I paid $52 for one ounce (30 ml). I had not done any research prior to my purchase and relied on the folks at the marijuana shop to sell me a good product. Buyer beware is the best advice I got from this article. I have not achieved any pain relief from this product and use about 1 ml under my tongue with the dropper in the bottle. I intend to find a full spectrum CBD oil and I hope to notice a difference in pain relief. Thanks for the great information.
"Comparisons of industrial hemp to hydrocarbon or other conventional industrial feedstocks show that, generally, hemp requires substantially less energy for manufacturing, often is suited to less-toxic means of processing, and provides competitive product performance (especially in terms of durability, light weight, and strength), greater recyclability and/or biodegradability, and a number of value-added applications for byproducts and waste materials at either end of the product life cycle."

With marijuana, apparently, we’re still waiting for this information. It’s hard to study a substance that until very recently has been almost universally illegal. And the few studies we do have were done mostly in the nineteen-eighties and nineties, when cannabis was not nearly as potent as it is now. Because of recent developments in plant breeding and growing techniques, the typical concentration of THC, the psychoactive ingredient in marijuana, has gone from the low single digits to more than twenty per cent—from a swig of near-beer to a tequila shot.
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.

Sometimes, products that claim to contain CBD don’t have any at all when tested, Blessing says. More commonly, though, cookies and beverages simply contain far less than 300 milligrams of CBD, which is the minimum amount she says has been found effective in the preliminary science so far.

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]
While CBD still faces legal hurdles to go mainstream, beverage giants, food companies and others have begun to take serious interest in the roughly $2 billion U.S. market. Tilray Inc. TLRY, +0.68%  announced a partnership with Anheuser-Busch InBev SA BUD, -1.34%  this week to research marijuana-based beverages, and Constellation Brands Inc. STZ, -0.03%   has invested heavily in pot producer Canopy Growth Corp. Other large companies, like Molson Coors Brewing Co. TAP, -0.17%  , have invested in research, and Coca-Cola Co. KO, -0.26%  and others have at least considered making a play for the space.
Subsequent studies were carried out in different countries, which confirmed the results found in the Zammit et al. (2002) study, showing that those clinically dependent on cannabis by 18 years of age had an increased risk of later developing psychotic symptoms (Fergusson, Horwood, & Swain-Campbell, 2003). Cannabis users were also more likely to develop schizophreniform disorder (Arseneault et al., 2002), and the dose–response relationship found in the first study was confirmed (Henquet et al., 2005).
So true. Hearst and Rockefeller did not want Hemp or any form of Cannabis interfering with their lucrative paper, pharmaceutical and oil industries. Hemp is versatile and renewable. It can be used for food, medicine, fuel, paper, clothing, plastic, building materials; just about anything paper and oil is used for. These bastard wealthy people have done a disservice to all people and for the sake of lining their already copiously rich pockets. They and those like them are criminals of the worst order
The self-medication hypothesis was not supported in either the van Os or Henquet studies. Both studies found that early psychotic symptoms did not predict an increased risk of using cannabis (as is required by the self-medication hypothesis). The direction of the relationships was from early cannabis use to psychosis. Their negative results have recently been supported by Verdoux et al. (2002), who examined the temporal relationship between cannabis use and psychotic symptoms using an experience sampling method. They asked 79 college students to report on their drug use and experience of psychotic symptoms at randomly selected time points, several times each day over 7 consecutive days. The sample included high cannabis users (n = 41) and an over-representation of students identified as vulnerable to psychosis (n = 16). Verdoux and colleagues found that in time periods when cannabis was used, users reported more unusual perceptions, and these relationships were stronger in vulnerable individuals. There was no temporal relationship between reporting unusual experiences and using cannabis use, as would be predicted by the self-medication hypothesis.
The DCE/SP began funding eradication programs in Hawaii and California in 1979.  The program rapidly expanded to include programs in 25 states by 1982.  By 1985, all 50 states were participating in the DCE/SP.  In 2015, the DEA continued its nation-wide cannabis eradication efforts, providing resources to support the 128 state and local law enforcement agencies that actively participate in the program.  This assistance allows the enhancement of already aggressive eradication enforcement activities throughout the nation.  In 2017, the DEA continued its nation-wide cannabis eradication efforts, providing resources to support the 126 state and local law enforcement agencies that actively participate in the program.   This assistance allows the enhancement of already aggressive eradication enforcement activities throughout the nation.  In 2017, the DCE/SP was responsible for the eradication of 3,078,418 cultivated outdoor cannabis plants and 303,654 indoor plants for a total of 3,382,072 marijuana plants.  In addition, the DCE/SP accounted for 4,502 arrests and the seizure in excess of 20.5 million dollars of cultivator assets.  The program also removed 2,829 weapons from cannabis cultivators.
Just as there was a shift from viewing disease as a state to thinking of it as a process, the same shift happened in definitions of health. Again, the WHO played a leading role when it fostered the development of the health promotion movement in the 1980s. This brought in a new conception of health, not as a state, but in dynamic terms of resiliency, in other words, as "a resource for living". 1984 WHO revised the definition of health defined it as "the extent to which an individual or group is able to realize aspirations and satisfy needs and to change or cope with the environment. Health is a resource for everyday life, not the objective of living; it is a positive concept, emphasizing social and personal resources, as well as physical capacities".[10] Thus, health referred to the ability to maintain homeostasis and recover from insults. Mental, intellectual, emotional and social health referred to a person's ability to handle stress, to acquire skills, to maintain relationships, all of which form resources for resiliency and independent living.[9] This opens up many possibilities for health to be taught, strengthened and learned.

"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."
The main difference between the two is in its chemical composition, specifically in tetrahydrocannabinol (THC). THC is the chemical responsible marijuana’s psychological effects.An average batch of marijuana contains anywhere from 5-20% THC content. Some premium marijuana can have up to 25-30% THC. Hemp, on the other hand, has a max THC level of 0.3%, essentially making it impossible to feel any psychoactive effect or get a “high”. This threshold is heavily regulated in other countries that have legalized hemp.Hemp also has high cannabidiol (CBD) content that acts as THC’s antagonist, essentially making the minimal amount of THC useless.
"From the colonial period through the middle of the nineteenth century, hemp was widely grown in the United States for use in fabric, twine, and paper.19 Production dropped by the 1890’s as technological advances made cotton a more competitive textile crop, and coarse fiber crops were increasingly imported.20 Nonetheless, American farmers continued to grow hemp into the middle of the twentieth century, finding it a useful rotation crop because it acted as a natural herbicide21—a dense, rapidly growing crop, it choked out weeds prior to the next planting of corn and other crops.22 At the urging of the government, production to supply fiber for military purposes was expanded enormously during World War I and again during World War II, particularly after the Japanese cut off exports from the Philippines."
The Levi’s Wellthread x Outerknown capsule collection just launched last March 4, in time for Spring/Summer. It features jackets, board shorts, shirts, tees, and jeans. The jeans and jackets were made using a 70/30 mixture of cotton and hemp respectively, while the hemp came from rain-fed crops that required no extra irrigation, which successfully reduced the need for water in growing it by 30%. Meanwhile, the t-shirts were made using both cotton-hemp blends as well as recycled denim.
In Western Europe, the cultivation of hemp was not legally banned by the 1930s, but the commercial cultivation stopped by then, due to decreased demand compared to increasingly popular artificial fibers.[148] Speculation about the potential for commercial cultivation of hemp in large quantities has been criticized due to successful competition from other fibers for many products. The world production of hemp fiber fell from over 300,000 metric tons 1961 to about 75,000 metric tons in the early 1990s and has after that been stable at that level.[149]
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.
Concrete-like blocks made with hemp and lime have been used as an insulating material for construction. Such blocks are not strong enough to be used for structural elements; they must be supported by a brick, wood, or steel frame.[28] However, hemp fibres are extremely strong and durable, and have been shown to be usable as a replacement for wood for many jobs, including creating very durable and breathable homes. The most common use of hemp lime in building is by casting the hemp and lime mix while wet around a timber frame with temporary shuttering, and tamping the mix to form a firm mass; after the removal of the temporary shuttering, the solidified hemp mix is then ready to be plastered with a lime plaster.[29]
The mosaic of laws that govern CBD legality across the globe varies just as much as the legislation across the US. Generally, CBD extract is legal in most countries, but what makes it illegal is where and what it’s extracted from. Most Group of 20 (G20) countries allow CBD extracted from industrial hemp, but not CBD extracted from whole-plant marijuana. Note, however, the differences between the two. Legislation regarding international travel with CBD also varies among countries. For the foreseeable future, the best practice would be to search online, or contact the respective embassies or consulates, before traveling to determine whether your CBD is safe and legal.
Laboratory evidence indicated that cannabidiol may reduce THC clearance, increasing plasma concentrations which may raise THC availability to receptors and enhance its effect in a dose-dependent manner.[23][24] In vitro, cannabidiol inhibited receptors affecting the activity of voltage-dependent sodium and potassium channels, which may affect neural activity.[25] A small clinical trial reported that CBD partially inhibited the CYP2C-catalyzed hydroxylation of THC to 11-OH-THC.[26]
This article reviews recent research on cannabinoid analgesia via the endocannabinoid system and non-receptor mechanisms, as well as randomized clinical trials employing cannabinoids in pain treatment. Tetrahydrocannabinol (THC, Marinol®) and nabilone (Cesamet®) are currently approved in the United States and other countries, but not for pain indications. Other synthetic cannabinoids, such as ajulemic acid, are in development. Crude herbal cannabis remains illegal in most jurisdictions but is also under investigation. Sativex®, a cannabis derived oromucosal spray containing equal proportions of THC (partial CB1 receptor agonist ) and cannabidiol (CBD, a non-euphoriant, anti-inflammatory analgesic with CB1 receptor antagonist and endocannabinoid modulating effects) was approved in Canada in 2005 for treatment of central neuropathic pain in multiple sclerosis, and in 2007 for intractable cancer pain. Numerous randomized clinical trials have demonstrated safety and efficacy for Sativex in central and peripheral neuropathic pain, rheumatoid arthritis and cancer pain. An Investigational New Drug application to conduct advanced clinical trials for cancer pain was approved by the US FDA in January 2006. Cannabinoid analgesics have generally been well tolerated in clinical trials with acceptable adverse event profiles. Their adjunctive addition to the pharmacological armamentarium for treatment of pain shows great promise.
