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.
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.
How much cbd oil to dtart with for diabetes
Knowing the right CBD dosage for diabetes is important for it to be truly effective. Let’s look at how you can incorporate CBD into your diabetes treatment. We’ll break down the dosage facts so you get the most from CBD. Let’s get started.
Does CBD Treat Diabetes?
Research on the benefits of CBD is new and ongoing, but there are promising studies about CBD and diabetes. However, they mostly have to do with prevention so far.
But that doesn’t mean that CBD can’t help with diabetes symptoms. In fact, since diabetes is an inflammatory disease and CBD is anti-inflammatory, it could be extremely beneficial.
CBD has been proven to be effective at reducing pain caused by inflammation, which is a common symptom among diabetes patients. Inflammation from diabetes can also cause damage to the walls of blood cells, which CBD can help prevent.
Now, let’s look at how to use CBD products to help with diabetes symptoms, and the right dosages.
CBD Dosage for Diabetes
Everyone responds to CBD differently, so there is no one size fits all dosage recommendation. In fact, the FDA actually prohibits companies from making dosage suggestions on their products.
The best way to find what dosage works for your diabetes symptoms is the use the stepwise dosing procedure. Start with a lower baseline dosage between two to five milligrams. Take this dosage two or three times a day for a week, then increase the dosage by one or two milligrams.
Continue taking the raised dosage for at least three days, and then increase it again if you think you need a more potent dose. Keep track of how you feel at each dosage level and notice the differences each time your increase the dose.
CBD is potent, so it won’t take long before you find the right dose for you. Once you find it, continue taking that dosage two or three times per day to help with your diabetes symptoms.
You can also adjust your dosage based on your weight and the form of CBD you are taking. Learn more about CBD dosage in this article from Green Flower Botanicals.
What Type of CBD is Best for Diabetes?
There are two main types of CBD oil: CBD isolate and full-spectrum CBD oil. While CBD isolate contains nothing but CBD and a carrier oil, full-spectrum CBD contains terpenes, essential oils, and other cannabinoids (but not THC, which is a controlled substance in the UK and most other countries). This is important to note because one of marijuana’s most abundant terpenes, Myrcene, has been used as Brazilian folk medicine to treat diabetes for centuries. More recently a 2007 study at the University of Jordan found that Myrcene lessened the effects of diabetes.
Again, since everyone reacts to CBD differently, there’s no one perfect suggestion for which type of CBD you should take. The more important thing is making sure you are using high-quality CBD from a company that is certified by a third party.
However, diabetics should also keep in mind that CBD gummies usually have added sugar. Most users report great results taking an oral CBD oil or capsules. Topical CBD creams can also help with pain due to diabetes inflammation.
CBD and Diabetes Final Thoughts
CBD offers plenty of health benefits that are still being discovered, so even if you find that it doesn’t directly impact your diabetes, it can have an indirect impact that’s still helpful. For example, CBD may help you sleep better, which is sometimes difficult for diabetes patients.
To find the perfect CBD dosage for diabetes, experiment with different amounts and forms of CBD for a few weeks. Let your doctor know that you are incorporating CBD into your daily routine as well, and always make sure you are taking a good quality product.
