Over the course of a lifetime, it’s a given that everyone will experience nausea at least a few times. It is a built-in biological function that is debilitating at worst and an inconvenience at best. In most cases, nausea can be resolved with fresh air, a glass of water, and a calm environment. But what if your nausea doesn’t subside so easily? Can CBD oil help?
For many people, nausea can be an overwhelming constant, an accepted symptom of illness, or even a side effect of medical treatment.
Advances in modern medicine have led to a wide range of treatments for a wide range of conditions. Unfortunately, those treatments often carry side effects, with nausea being one of the most common. Many times patients are left with few options—the medicine is necessary and the nausea becomes something you just have to live with.
But, the truth is, you don’t have to just accept it. Using CBD oil for nausea relief can be an effective, natural, way to regain control of your life.

There are hundreds of cannabinoids present in cannabis and hemp plants; cannabidiol (CBD) is just one of them. CBD has been found to offer many potential benefits to human health without causing the intoxication most commonly associated with THC and marijuana consumption. In other words, CBD will not get you high.
By working with the body’s cannabinoid receptors, CBD has been found to produce a range of beneficial effects, including reducing nausea and vomiting.
Most anti-nausea and antiemetic drugs are a saving grace for people who experience debilitating nausea. But because nausea can be caused by a variety of factors, and because the science behind what causes nausea is not clear, there are many different medications that can be prescribed, and finding the right one can require a bit of trial and error. CBD oil may be able to eliminate some of this back and forth.
In chemotherapy, for example, there are three different types of antiemetics available, yet each has a completely different function. One targets dopamine receptors; another, serotonin receptors; and the last targets NK1 receptors. What works for one person may not work for another. And what’s worse, many of these medications carry side effects. CBD oil does not have complicated side effects and may present as a better solution.

As you can see, many of these drugs carry detrimental side effects including continued nausea and diarrhea. Considering this, it isn’t surprising that people are looking to CBD oil as a potentially safer, more effective option for nausea relief.
Nausea is complicated and the science is unclear about what exactly causes it. But, what is starting to become clear, is that CBD oil may be able to relieve nausea.
In fact, one of the medications approved for use in chemotherapy-related nausea is Nabilone, a synthetic cannabinoid. Nabilone is used after all other medical treatments have failed. This particular drug is actually a synthetic THC—not CBD—but it points to the fact that the solution to nausea may lie in the endocannabinoid system.
While the causes of nausea remain a mystery, one theory suggests that it is caused by an increased release of serotonin. Serotonin is a neurotransmitter that, when present in large amounts, can leave you feeling queasy. CBD oil is able to counteract this effect by interacting with the receptors responsible for releasing serotonin into the body.
Nausea induced by chemotherapy treatment can present itself in various forms, namely as symptomatic nausea, caused directly by the impact of chemotherapy drugs on the body, and anticipatory nausea, your body’s preemptive response to situations that have triggered nausea or vomiting in the past.
While symptomatic nausea can be treated with antiemetics, this is not the case with anticipatory nausea. A known experience in patients who have suffered from bouts of post-treatment nausea in the past, anticipatory nausea begins before any physical nausea is felt. For those undertaking chemotherapy treatment, CBD oil may provide relief from the symptoms of both symptomatic and anticipatory nausea.
It is thought that CBD oil reduces the experience of nausea by impacting the 5HT1A, or serotonin, receptors in the brain, which are thought to cause nausea and vomiting. When CBD binds to these receptors, signals to reduce serotonin production are sent to the forebrain. By blocking the release of serotonin, CBD is able to stop nausea at its source.
A study on THC and CBD’s effect on anticipatory nausea specifically also showed promising results. In the study, shrews were exposed to cues while vomiting was induced to create a cognitive connection between the two. When the test subjects were given THC or CBD before being exposed to the same cues that were tied to episodes of nausea and vomiting, they did not experience anticipatory nausea.
There is a great deal of research that still needs to be done to understand the impact CBD oil can have on nausea, and the mechanisms behind its anti-nausea and antiemetic properties. But at the moment, using CBD oil for nausea may be just as effective as using traditional medications, minus the harsh side effects.
Before you consider taking CBD oil for nausea, it is important to first speak to your doctor. While generally safe, CBD oil can interact with a few common medications and so you will want to make sure you’re not facing any risks.
Once you have been cleared to use CBD oil, you will need to decide how you want to take it. In most cases, the delivery format you choose will depend on your needs and personal preferences. For conditions like nausea, however, some products will make more sense than others.
CBD vape oil and CBD flower are inhaled, meaning the CBD can avoid the digestive system and is absorbed directly into the lungs. The effects appear within minutes, offering the fastest nausea relief. The downside to using a CBD vape or flower is the benefits do not last long (typically 30 minutes to an hour) and it may be necessary to take another dose for relief from chronic nausea. And, of course, it may not always possible or desirable to vape or smoke.
This is where CBD oil drops and tinctures can be effective. These products bypass digestion as well and are absorbed through the skin under the tongue. They do not work as quickly as CBD vapes or flower, but they are the next best thing. You can expect relief within 30 minutes and the benefits to last anywhere from 2-4 hours. CBD drops and tinctures provide the best dosage control, giving you the ability to measure your dosage down to the literal drop.
CBD oil capsules and edibles can also be used as part of a daily supplement routine. However, because they must pass through the digestive system, they take the longest for your body to process. Too, if you have a sensitive stomach, adding more digestables to the mix may not be an ideal option.
There is no universal dose of CBD oil for nausea. Because no two people will respond in exactly the same way, it is best to begin by following the recommended serving suggestion that comes with your CBD oil product.
If you’re looking for personalized dosage advice, talk to a cannabis doctor who can assess your specific condition and give you a more tailored recommendation.
Or, you can go by our suggestion if your CBD product doesn’t come with dosage instructions. At CBD Oil Review we have analyzed hundreds of products and come up with a standard serving suggestion:
The CBD Oil Review Serving Standard is 25mg of CBD, taken twice daily.
If you are not getting results from this amount, we recommend increasing the serving size by 25mg every 3-4 weeks until you find relief.
