CBD & Diabetes
CBD—short for cannabidiol, a part of cannabis (marijuana)—has gotten a lot of attention lately. With changes in the legal status of cannabis, CBD has gone from a criminalized substance to being called a miracle drug. You can find CBD oil supplements, as well as foods, drinks, and lotions in stores and pharmacies across the U.S. and worldwide. However, research on the effects of CBD on the body is still limited and so far no CBD products have been approved by the Food and Drug Administration (FDA).
What to Know
Along with tetrahydrocannabinol (THC), CBD is the major element of cannabis. But CBD does not cause the “high” that many feel from using cannabis. For decades, CBD was considered inactive, but last year, the FDA approved it under the brand name Epidiolex for a rare form of childhood epilepsy (at a much higher dose than is available in supplements). Researchers are in the very early stages of exploring other potential uses for CBD, including relieving anxiety, insomnia, chronic pain, and inflammation.
There’s a lot of hype surrounding CBD oil and diabetes. There is no noticeable effect on blood glucose (blood sugar) or insulin levels in people with type 2 diabetes. Researchers continue to study the effects of CBD on diabetes in animal studies.
Although CBD is well tolerated by most people, there are side effects. It can suppress immune responses, raise eye pressure (which may worsen glaucoma), and increase blood levels of certain medications, such as the blood thinner Coumadin, which can lead to serious bleeding. Talk to your doctor if you’re thinking of trying CBD.

CBD sits in a gray area. While used as a medicine, it’s also a natural compound. Many effective medications are derived from compounds found in nature, but a lot of work goes into identifying the specific, active compound and determining what dose is safe and effective. Researchers aren’t close to that yet with CBD oil.
Its status as a supplement makes things tricky, too. Because CBD is not regulated by the FDA, creators of these supplements often make claims about its effectiveness based on little—or no—evidence. It’s hard to know what you’re getting. The amount of CBD in any product varies widely. The FDA has warned that in some products, lab tests have shown no CBD at all. Under the FDA’s Dietary Supplement Health and Education Act, manufacturers of dietary supplements and dietary ingredients are banned from marketing products that are tainted or misbranded.
Although many claims continue to be made about CBD oil, there is little evidence of any benefit. It’s certainly not an alternative to traditional diabetes management. The safety of CBD is also unknown—it may have dangerous side effects that we won’t know about unless further research is done. But there is a great deal of interest in CBD research, so we should learn a lot more in the coming years about what exactly CBD can and can’t do. In the meantime, it’s best practice pursue optimal health and diabetes management with treatments that have evidence to show they are safe and effective.
How Do You Use CBD Oil for Diabetes?
CBD oil has long been championed for its wide variety of health and wellbeing benefits, including its calming properties and help with alleviating anxiety, insomnia and muscle pain. There are always studies to determine its uses for specific health conditions and, even in early stages of research, diabetes.
In fact, many people already use CBD to relieve symptoms of diabetes, though studies are still limited for the time being. That’s why we’re taking a closer look at just how CBD oil can offer help for those with this chronic condition.
Is CBD Oil Good for Diabetes?
In simple terms, diabetes is a long-lasting health condition that affects how the body turns food into energy. When we eat and sugar enters the bloodstream, the pancreas releases insulin, inviting the glucose (broken down sugar) into the body’s cells and converts it into energy. According to research from The Centers For Disease Control and Prevention (CDC) , when an insufficient amount of insulin is produced in the body – or if the cells do not respond to the insulin as they should – a person can develop diabetes. In turn, this can increase the risk of various health conditions including stroke, glaucoma, heart disease, cataracts and kidney disease.
While there’s currently no cure for diabetes, there are many over-the-counter medications available to help control its symptoms. But can we add CBD oil to that list?
While no clinical trials have specifically tested whether pure CBD oil can prevent type 1 and type 2 diabetes in humans, a handful of preliminary studies conducted on mice have had decidedly positive results. We’ve already established that insulin plays a prominent role in the regulation of glucose homeostasis – or, in less sciencey talk, the state of steady internal, physical, and chemical conditions. In fact, one study has confirmed that the CB1 endocannabinoid system regulates adipocyte (fat cells) insulin sensitivity, which helps to maintain glucose levels in the body. So if you were wondering whether CBD oil can help lower blood sugar levels, it’s looking promising!
There’s also been a lot of research into CBD’s anti-inflammatory properties. A 2007 study on inflammation caused by high glucose (HG) levels revealed that CBD exerts potent anti-inflammatory and antioxidant effects which lower the incidence of diabetes in non-obese diabetic mice. In fact, all effects of HG during the trial were reduced by CBD pretreatment.
In addition to its inflammatory properties, we know that many people take CBD oil for pain relief – but this time we’re not talking about those aching post-gym muscles. The results of a 2017 animal study revealed that CBD effectively reduces diabetes-related nerve pain such as neuropathy, which causes numbness, tingling, and muscle weakness. Usually treated with strong prescription painkillers, you can now skip the lengthy chemist queues (and often woozy side effects) for a 100% natural remedy, instead! Thank us later.
How Much CBD Oil Should You Take for Diabetes?
The best CBD dosage for diabetes will depend on your general tolerance and, as with taking CBD for any condition, you should build up a tolerance slowly over time. At Good Hemp, we’ve done our research and can reveal that the average CBD dosage is 20-40mg at a time – and depending on why you’re taking it, that may not be the right amount for you. Whether you drop it in your morning coffee , take it under the tongue, or carry a tincture in your bag for on-the-go use, we recommend that you don’t exceed a maximum daily intake of 70mg, especially if you’re new to it.
Research is still in its early stages with regards to CBD’s effects on people with diabetes. However, the results suggest that, at the very least, it is absolutely safe for people with diabetes to take CBD oil, and the benefits can help alleviate some symptoms – particularly nerve pain, inflammation and insomnia. Want to give it a whirl for yourself? Grab a tincture or two of CBD oil from Good Hemp today and you’ll be reaping the benefits in no time!

CBD for Type 2 Diabetes: What Are the Benefits and Risks?
The trendy complementary treatment is rising in popularity. Here’s what you need to know before you use CBD to manage type 2 diabetes.
CBD may help relieve symptoms that can contribute to high blood sugar in type 2 diabetes. Everyday Health
You probably don’t have to look farther than your local drugstore or beauty product supplier to know CBD has taken a starring role in everything from sparkling water and gummies to tincture oils and lotions. Some may even say that cannabidiol (CBD) — which, like THC, is a component of the cannabis plant, but doesn’t contain its psychoactive effects — is the “it” ingredient of our age.
You’ve probably also heard that CBD can help lessen stress, anxiety, and pain. “When people are in pain, they have a stress response, which causes an increase in cortisol and an increase in blood sugar,” says Veronica J. Brady, PhD, CDCES, a registered nurse and an assistant professor at the Cizik School of Nursing at the University of Texas in Houston. Relieving pain can help alleviate the stress response and improve blood sugar levels, as well as aid sleep, she says.
If you’re managing type 2 diabetes, it’s natural to be curious about whether CBD might help you manage those symptoms, too, to help stabilize your blood sugar. In fact, the prevalence of cannabis use increased by 340 percent among people with diabetes from 2005 to 2018, according to a study published in Drug and Alcohol Dependence in July 2020, which surveyed people on their use of cannabis (CBD or THC, in any form) in the previous 30 days.
But does it work for treating diabetes? Some healthcare professionals say CBD may have a role to play, but it’s important to understand that the only health condition CBD has proved effective for is epilepsy in kids. The jury is unfortunately still out, owing to the lack of comprehensive research on CBD and type 2 diabetes.
Still, in the aforementioned survey, 78 percent of people used cannabis that was not prescribed by a doctor. “Diabetes patients might still use cannabis for medical reasons, but not have a prescription,” says Omayma Alshaarawy, MBBS, PhD, an assistant professor in the department of family medicine at Michigan State University in East Lansing, who led the study. Recreational use is another factor. She points to a separate study, published September 2019 in the Journal of the American Medical Association, that found that more than 50 percent of people with medical conditions such as diabetes or cancer use cannabis recreationally.
How People With Type 2 Diabetes Are Using CBD
In Nevada, where Dr. Brady used to work as a certified diabetes educator, her patients with type 2 diabetes used CBD for nerve pain. She says patients would use CBD in a tincture or in oils that they rubbed on painful areas, including their feet. Patients could buy CBD at medical marijuana dispensaries, which would offer dosing instructions. “They worried about the impact on their blood sugars,” says Brady.
Ultimately, though, Brady says that her patients reported that CBD reduced their nerve pain and improved their blood sugar. She adds that those people who used CBD oils for nerve pain also reported sleeping better.
Heather Jackson, the founder and board president of Realm of Caring in Colorado Springs, Colorado, a nonprofit that focuses on cannabis research and education, senses an interest in CBD within the diabetes community. “In general, especially if they’re not well controlled, people are looking at cannabinoid therapy as an alternative, and usually as an adjunct option,” says Jackson. Callers have questions about CBD for neuropathy pain, joint pain, gastrointestinal issues, and occasionally blood glucose control, according to a spokesperson for Realm of Caring.
The organization receives thousands of inquiries about cannabis therapies a month. It keeps a registry of these callers, where they live, and their health conditions. Jackson says that people with type 2 diabetes are not a large percentage of the callers, but they currently have 540 people with diabetes in their database.
Jackson says that Realm of Caring does not offer medical advice, and it does not grow or sell cannabis. Instead, it offers education for clients and doctors about cannabis, based on its ever-growing registry of CBD users, their conditions, side effects, and administration regimen. “We are basically educating,” says Jackson. “We want you to talk to your doctor about the information you receive.”
Scientific Studies on CBD and Type 2 Diabetes, and Barriers to Research
Despite interest among people with type 2 diabetes, large, rigorous studies showing how CBD may affect type 2 diabetes are lacking, says Y. Tony Yang, MPH, a doctor of science in health policy and management and a professor at George Washington University School of Nursing in Washington, DC. Specifically absent are randomized controlled trials, which are the gold standard of medical research.
Early research suggests CBD and diabetes are indeed worth further study. For example, a small study published in October 2016 in Diabetes Care in the United Kingdom looked at 62 people with type 2 diabetes and found that CBD did not lower blood glucose. Participants were not on insulin, but some took other diabetes drugs. They were randomly assigned to five different treatment groups for 13 weeks: 100 milligrams (mg) of CBD twice daily; 5 mg of THCV (another chemical in cannabis) twice daily; 5 mg CBD and 5 mg THCV together twice daily; 100 mg CBD and 5 mg of THCV together twice daily; or placebo. In their paper, the authors reported that THCV (but not CBD) significantly improved blood glucose control.
Other CBD research is still evolving. Some CBD and diabetes studies have been done in rats, which leads to findings that don’t always apply to human health. Other studies have looked more generally at the body’s endocannabinoid system, which sends signals about pain, stress, sleep, and other important functions. Still other studies, including one published in the American Journal of Medicine, have looked at marijuana and diabetes, but not CBD specifically.
That there are so few studies of CBD in people with type 2 diabetes has to do with a lack of focus on CBD as an individual component. Historically, cannabinoids (a group of chemicals in the cannabis plant) have been lumped together, including CBD, THC, and more than 100 others. The 1970 U.S. Controlled Substances Act classifies cannabis as a Schedule 1 drug with the highest restrictions. Currently, 33 states and the District of Columbia allow cannabis for medical use and 11 states allow cannabis for recreational use.
The 2018 Farm Bill removed industrial hemp from the controlled substances list, clearing the way for more production and research of CBD. Meanwhile, growers and manufacturers are better able to isolate CBD, mainly by cultivating industrial hemp that is high in CBD and very low in THC, says Jackson. So, perhaps in the coming years, more research on CBD and diabetes will emerge.
How the FDA Views and Regulates CBD for Disease Treatment
Yet, as evidenced by the July 2020 study in Drug and Alcohol Dependence, people with type 2 diabetes aren’t waiting for further study to hop on the trend. Brady says her patients have been open about using CBD, particularly the younger patients. She says one of her older patients was initially uncomfortable about buying CBD in the same shop that sold marijuana but eventually gave in. Brady adds that many people associate CBD with smoking marijuana, despite their distinctly different effects on the body.
The U.S. Food and Drug Administration (FDA) approved the first CBD medication in 2018, for treating childhood epilepsy. Currently, there is no other FDA-approved CBD medication for diabetes or any other condition, according to the FDA. In December 2018, the FDA said it was unlawful under the Federal Food, Drug, and Cosmetic Act to sell food or dietary supplements containing CBD. In April 2019, the FDA stated that it would be taking new steps to evaluate cannabis products, and it held a public hearing about cannabis products in May 2019.
“The FDA, for the time being, has focused its limited enforcement resources on removing CBD products that make claims of curing or treating disease, leaving many CBD products for sale,” wrote Pieter Cohen, MD, and Joshua Sharfstein, MD, in a July 2019 perspective in the New England Journal of Medicine. Dr. Cohen is an assistant professor of medicine at Harvard Medical School in Boston, and Dr. Sharfstein oversees the office of public health practice and training at the Johns Hopkins Bloomberg School of Public Health in Baltimore.
Precautions for People With Diabetes Looking to Try CBD
For the CBD products already on the market, Jackson says it’s often difficult to know what’s inside. A study published November 2017 in the Journal of the American Medical Association found that only 30 percent of CBD products were accurately labeled, with under- and over-labeling of CBD content, and some products containing unlisted chemicals such as THC.
Vaping liquids were the most commonly mislabeled CBD products in the study. The International Research Center on Cannabis and Health in New York City warns that consumers should not purchase vape products from unregulated and illicit markets. A small investigation by the Associated Press in 2019 showed that some CBD vapes had synthetic marijuana.
Jackson points out that CBD may affect certain cholesterol and blood pressure drugs, and a study published in June 2017 in Cannabis and Cannabinoid Research detailed these interactions. Other side effects of CBD include tiredness, diarrhea, and changes in weight or appetite, the researchers write.
“What you put in your body is really important,” says Jackson, adding that’s especially true for people with major health conditions like diabetes. Jackson speaks from personal experience as a mom finding CBD treatments for her son’s epilepsy. She says consumers should ask manufacturers whether CBD products are free of mold, pesticides, and other toxins.
Realm of Caring, Jackson’s nonprofit, created a reference sheet for evaluating products and manufacturers. It also endorses products that adhere to standards such as those from the American Herbal Products Association and the FDA’s Current Good Manufacturing Practice regulations.
“There is little known about cannabis health effects, especially among patients with chronic conditions. Research is growing, but still solid evidence evolves,” says Dr. Alshaarawy. For these reasons, she recommends that patients talk to their doctors so they can discuss the benefits and potential harms of cannabis and monitor their health accordingly.
How to Talk to Your Healthcare Provider About Using CBD for Type 2 Diabetes
Jackson and Brady advise people who are considering CBD for diabetes to ask their providers about the complementary therapy before adding it to their treatment plan. Brady says it’s difficult to find research about CBD and type 2 diabetes, even in her capacity as a diabetes educator. Still, in her experience, if people are looking for a natural way to manage pain, it’s worth a conversation with their healthcare provider. “It’s something that should be talked about, especially if they’re having significant amounts of pain, or really any pain at all associated with their diabetes,” says Brady.
“It’s a reasonable alternative,” says Brady. “As it gains in popularity, there needs to be some information out there about it.
