An actual long term study, Ganja in Jamaica: A Medical Anthropological Study of Chronic Marijuana Use, which was published in the Journal of the American Medical Association in 1975, showed zero concerns with addiction, even after patients who had used cannabis for decades had stopped. The 1980 study Cannabis in Costa Rica: A Study in Chronic Marijuana Use backed this up. Most interestingly, studies like this are not finding any addictive potential with CBD even in the presence of THC!
Naturally, the testimonies of these experts were based on a comprehensive literature review, an endeavor which we have also undertaken, albeit in a less official capacity. While many new products have been hailed as a panacea in their times, and many web sources certainly allude to this status for CBD, our objective was more modest – presenting ten possible benefits of cannabidiol where sufficient evidence exists to back up the claims.

In fact, numerous studies have looked at the relationship between CBD and pain, and the results are promising. Researchers have looked at various kinds of pain – from joint pain to cancer pain. One finding is that CBD increases levels of glutamate and serotonin – both neurotransmitters that play a role in pain regulation. And CBD’s anti-inflammatory properties help by tackling the root cause of much chronic pain.
In addition to acting on the brain, CBD influences many body processes. That’s due to the endocannabinoid system (ECS), which was discovered in the 1990s, after scientists started investigating why pot produces a high. Although much less well-known than the cardiovascular, reproductive, and respiratory systems, the ECS is critical. “The ECS helps us eat, sleep, relax, forget what we don’t need to remember, and protect our bodies from harm,” Marcu says. There are more ECS receptors in the brain than there are for opioids or serotonin, plus others in the intestines, liver, pancreas, ovaries, bone cells, and elsewhere.
In fact, the U.S. Food and Drug Administration (FDA) approved Epidiolex (a drug made with a purified form of CBD oil) in June 2018 for the treatment of seizures associated with two rare and severe forms of epilepsy in patients 2 years of age and older. These two epilepsy forms are known as Lennox-Gastaut syndrome and Dravet syndrome. Epidiolex is the first FDA-approved drug that contains a purified drug substance derived from marijuana.
Cannabinoid therapy is connected to the part of the biological matrix where body and brain meet. Since CBD (cannabidiol) and other compounds in cannabis are so similar to the chemicals created by our own bodies, they are integrated better than many synthetic drugs. According to Bradley E. Alger, a leading scientist in the study of endocannabinoids with a PhD from Harvard in experimental psychology, “With complex actions in our immune system, nervous system, and virtually all of the body’s organs, the endocannabinoids are literally a bridge between body and mind. By understanding this system, we begin to see a mechanism that could connect brain activity and states of physical health and disease.”[175]
The store-bought hemp products typically contain hemp seed oil that provides just trace amounts of cannabidiol and thus they can’t be considered as a CBD supplement. The top quality CBD oil is obtained from the stalks of the selected hemp cultivars. It provides the higher percentages of cannabidiol by weight and provides some astonishing medical perks.
The anxiolytic effect of THC is well documented, with other cannabinoids (especially CBD) also providing relief (if less potent). The exact pathways of the process have not been identified. A preliminary study published in 2013 in the International Neuropsychopharmacology Journal has set the foundations for further research linking CBD to future treatments for depression and psychosis.[25]
If you live in a state where CBD is legal for your condition, it’s best to buy it from a state-regulated dispensary. But even there, oversight is uneven. “I feel safe being a cannabis consumer in Colorado, since the state tracks everything from seed to sale, but I didn’t the first few years after cannabis became legal,” when the rules were still taking shape, says Robyn Griggs Lawrence, the Boulder author of The Cannabis Kitchen Cookbook, which features recipes for cannabis edibles.

More human studies are needed to fully understand the range of risks and side effects that CBD oil may cause. Studies of CBD oil aren’t common. This is partially because Schedule 1 substances like cannabis are highly regulated, causing some obstacles for researchers. With the legalization of marijuana products, more research is possible, and more answers will come.

Hi Colleen, it's almost a year later and I'm wondering how you're doing. I'm experiencing a recurrence of Stage 3 ovarian, originally diagnosed in 2011. I've decided to get some chemo, not sold on another 6 cycles though. As a new MMJ patient, I'm still going to go through with Rick Simpson Oil (THC+CBD,) and I just joined a program with my local dispensary to get CBD capsules for $2 each when I order them at least 30 at a time. I hope you're doing well!! I'm off to do more research on dosing. **NOTE: If you have ANY experience with CBD treatment of ovarian cancer, PLEASE respond. Thank you!!
This taboo, which started around the same time that the US government outlawed cannabis, continues to slow down the progress for medical research around CBD. The FDA and DEA refuse to change their stance on cannabis, which is quite odd considering the US government holds onto a patent that highlights the benefits of CBD. Ultimately, all of this taboo and restrictions have inhibited extensive research around CBD and all the other cannabinoids in cannabis. (Cannabis is known to have 85+ different cannabinoids, many of them potentially having health benefits)
I found your article to be very informative. My son has refractory Epilepsy and Type 1 Diabetes. I am very interested in CBD but I am concerned about how it will interact with the 3 AED’s he is currently taking as well as how it will affect his blood glucose levels as he is on an insulin pump. Do you know of anyone with a similar combination of issues? How they have handled introducing CBD to their regime? And if they are seeing positive results?

With some of the dreadful reactions I have had to medications I mostly say no to drugs. The psychotropics turn me psycho. I read about addictions and have been through thus…I went off cold turkey with pain medication, antidepressants, anti psychotics, anti anxiety…I do not care to go through anything like that again. If I can get something stronger than an OTC I only want a low dose and do not want to go through what I did in 2010 again. This is where I am currently. Maybe my pain is not as severe as pain is for others. I do know what withdrawal is like and…I have had a good life all in all. I endeavor to be content and learn what I can. I do know what does not work for me.
During the study, 50 participants with PTSD coexisting with alcohol use disorder will be given either 400 milligrams of CBD daily, or a placebo. The goal is to see if the participants who take CBD end up drinking less and whether this leads to an improvement in PTSD symptoms. The participants will be given a pharmaceutical-grade CBD, which is more reliable in strength and purity than the supplements that are currently available for sale to the public.
For immediate medicinal effects, vaporizing or smoking work well. This can be helpful for either initial sleep onset or for wakefulness in the middle of a rest period but only lasts one to three hours. The medication effect is immediate, whereas most ingested products take thirty to sixty minutes before taking effect (faster on an empty stomach) and last six to eight hours. Vaporizers that use a cartridge filled with the CO2 concentrate are convenient and highly effective, and these are available in various ratios of CBD to THC. Herbal vaporizers that use the whole plant are also an effective delivery method. Sublingual sprays or tinctures taken as liquid drops also take effect quickly and last longer than inhaled products.
To meet legal standards in the United States, CBD oil and other products may contain up to 0.3% THC; low enough to avoid all psychoactive effects, but enough to potentially appear on a sensitive drug test. Kat’s Naturals, however, sells CBE products of the utmost purity, containing 0% THC, and free from pesticides, chemicals, and contaminants. The company works with organic hemp cultivated in the Netherlands, and extracts its CBD using a broad-spectrum critical CO2 process, retaining a high amount of omega 3’s and 6’s (heart-healthy fats), vitamins, and phytochemicals. Kat’s Naturals is also big on using synergistic essential oils- also organic- to enhance their CBD’s therapeutic effects. The best CBD for anxiety in their lineup is Relax, a tincture that combines 300 mg CBD, Organic Hempseed oil, and wild orange essential oil, along with Hops oil, a potent calming botanical which has been used to promote sleep since ancient times. Kat’s Naturals recommends this product explicitly as a great CBD for anxiety, as well as for promoting sound sleep, making this an excellent choice for anxiety-induced insomnia.
Dosage is important, because CBD can have side effects—the most common are tiredness, diarrhea, and changes in appetite and weight—so it’s best not to take more than you need. As CBD becomes more prevalent, says J. Michael Bostwick, M.D., a psychiatrist at Mayo Clinic in Rochester, MN, “I’m reasonably certain new kinds of side effects will emerge.”

In fact, numerous studies have looked at the relationship between CBD and pain, and the results are promising. Researchers have looked at various kinds of pain – from joint pain to cancer pain.

As you’ve probably already heard, the hemp plant itself is a highly useful plant, and every part of it has been used to make a wide variety of products, including biofuel and medicine. Biofuel made from hemp seeds is far less expensive and more effective than ethanol derived from corn. If there weren’t so many federal restrictions, growing hemp would highly benefit any agricultural state, but unfortunately most states must pay an absurdly high premium to import hemp seeds. And of course, as you’re probably aware, both THC and CBD seem to be immersed in a constant struggle of medical legality that I simply don’t have the time to address in this post.
CBD may help reduces REM behavior disorder in people with Parkinson’s disease. REM behavior disorder is a condition that causes people to act out physically during dreaming and REM sleep. Typically, during REM, the body is largely paralyzed, a state known as REM atonia. This immobilization keeps sleepers from reacting physically to their dreams. In REM behavior disorder, this paralysis doesn’t occur, leaving people free to move—which can lead to disruptive sleep and to injuring themselves or their sleeping partners. Cannabis may also work to reduce pain and improve sleep quality in people with Parkinson’s disease.
CBD oil is most readily available as a tincture. This can be taken by applying a few drops under your tongue, holding in your mouth for a few moments so it can be absorbed, before swallowing. It can also be added to water or smoothies. A spray form is available (simply spritz under your tongue), as are capsules, creams that can be applied topically, and e-liquid for vape pens.
Francesca Fusco, MD, a dermatologist based in New York City, recently told Health that CBD oil is a rich source of fatty acids and other skin-healthy nutrients, and that it may improve hydration and minimize moisture loss. A few studies have also suggested that CBD oil may inhibit the growth of acne, although this hypothesis has only been tested in laboratory cell cultures—not in actual humans.
Hi Diane, how did you go on with the CBD oil please. If it worked how long before you saw any results. I'm scared of flaring everything. Nerve damage across buttocks from a surgeon who found the nerve stuck to the bulge during a laminectomy operation and prised it off. I haven't sat for 5 years and getting worse. A muscle in my buttock is now throbbing constantly and causing pain to the muscle above. I've only started taking it today but the muscle pain is still as painful. Does it take a while for it to work. Only started on low dose to see what happens. Thank you Lyn
Like Elixinol, CBD Essence has been around for quite a few years and they definitely know a thing or two about hemp oil. The owner Don has actually been around the pharmaceutical industry for some years, and therefore knows how to deliver a quality and effective product. All of their oils are created using CO2 extraction methods, which have been known to be safer and more effective than solvent-based extraction. They avoid CBD isolates, and they always disclose lab test results to ensure there are no heavy metals or contaminants in the oil.

Hi Ben. What are your thoughts on the differences, if any, between CBD extracted from hemp (legal to buy for anyone in the US) and CBD extracted from medical cannabis? My instinct is that once extracted, they should be identical because we’re talking about a specific molecule (similar to how ascorbic acid extracted from an orange or bell pepper or made in a lab are identical). However, I had some CBD oil from a major retail website that did not do much for my insomnia, even at high doses. Then I tried some CBD oil from my medical marijuana doc that he claimed was pure CBD (meaning no THC, but I am not sure if there are other terpenes) and of higher quality because it was extracted from medical grade cannabis. I was totally skeptical, but ending up feeling it big time – very calming, almost like being high, but without the random racing thoughts that THC gives me. I am wondering if it’s worth it to shell out for my doc’s product (it is super expensive), or if I should just try another version of hemp-based CBD, such as the one you recommend.


CBD hemp oil has a number of uses and comes in many forms including capsules, tinctures, sublingual supplements, liquid oil, oil as a paste, sprays, salves, creams and in edible forms, such as candies or sweets. You can also inhale CBD oil from vapor-releasing pens, similar to the technology for e-cigarettes. This variety also provides a lot of controlled flexibility in terms of concentration, making CBD hemp oil useful and desirable for people of all ages, economic means, and personal needs.

CBD is a safe, long-term aid which is why it has gained such momentum and why our customers are turning to it for relief. CBD, scientifically known as cannabidiol, is a non-psychoactive, natural compound found in the hemp plant. When it interacts with the body’s endocannabinoid system, CBD provides powerful health benefits without the side effects of conventional drugs.

The researchers leading many of the studies on marijuana extracts and obesity are affiliated with the UK’s GW Pharmaceuticals, which makes me cringe that pharmaceutical companies are going to make some kind of very expensive CBD-based weight loss drug.  But regardless of motive, in these studies, the researchers found that the two compounds, THCV and cannabidiol, boosted metabolism, and reduced levels of liver fat, and blood cholesterol. These same compounds also made mice more sensitive to insulin, protected the cells that produce insulin, and increasing metabolic rate – all while suppressing the appetite. Nice.

Dispensaries: In states where marijuana is legal for recreational use, dispensaries are a common sight. They are much rarer in states with more restrictions. In states that permit the use of medical marijuana, hemp-based CBD oils do not normally require a prescription but marijuana-based oils do. Like brick-and-mortar locations, dispensaries offer more customer service. However, as noted, this may not be an option depending on the buyer’s state of residence. Also, CBD oil prices tend to be significantly higher at dispensaries.
Almost ten percent of people worldwide deal with acne. It’s a pretty common skin condition, even among adults. A few major factors can cause acne. Those are usually genetic makeup, bacterial infection, underlying skin inflammation, and sebum overproduction. Sebum is an oily secretion that lubricates our skin. It forms inside of sebaceous glands, which are under our skin.

Improving the appearance of the skin, especially reducing the signs and symptoms of acne and eczema, are the great benefits of regular CBD oil use. Topical application is quite popular for this, whether in a diluted or undiluted form, depending on the severity of the skin affliction. The powerful anti-inflammatory properties of the oil can also soothe redness, itchiness, and swollen areas of the skin.

Hi Marilyn, I would recommend a topical lotion or salve to start for instant relief.. Maybe 250 to 300 mg tincture to see how you feel. For me, the salve took the pain in my hands away in under a minute. I didn't notice how much the tincture worked until I forgot to take on vacation. Pain that was pretty much gone but came back, I was tired, grumpy and felt horrible. It works, just need to find right product and dosage for you.
All this means that scientists can still only obtain marijuana-derived CBD from farms licensed by the National Institute on Drug Abuse (which until this year meant only one farm owned by the University of Mississippi). As for whether you should have a preference for CBD that comes from hemp, marijuana, or a pure synthetically produced version, there are some theories that THC—and even the smell and taste of cannabis—might make CBD more effective, but Bonn-Miller says these ideas have yet to be proven.
So am I to assume, due to no response/deleted comment that my simple question was too difficult to answer? With all the technical & correct information you have on you GREAT website, can someone (?) not simply correct or acknowledge the FACT the your NOT using nano-particle size product? I am truly interesting (for my wife) in CBD, have done my research, and I love working with numbers which is why if found this discrepancy. Comments welcome, but avoidance is disturbing.
