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.

围绕CBD油和糖尿病有很多炒作。对人们的血糖（血糖）或胰岛素水平没有明显的影响type 2 diabetes. Researchers continue to study the effects of CBD on diabetes in animal studies.

尽管CBD是well tolerated by most people, there are side effects. It can suppress immune responses, raise eye pressure (which may worsenglaucoma），增加某些药物的血液水平，例如血液更薄的香豆素，这可能导致严重出血。如果你在考虑尝试CBD，请与您的医生交谈。

CBD坐在灰色区域。虽然用作药物，但它也是一种天然化合物。许多有效的药物来自于本质上发现的化合物，但大量工作进入鉴定特异性，活性化合物并确定剂量是安全可有效的。研究人员与CBD油没有接近那样。

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.
