While we’re still researching and learning about cannabidiol (CBD), what we know so far is promising.

People take CBD for a bunch of reasons. Some claim it helps with anxiety and chronic pain. Others find CBD helpful for dealing with nausea.

Below, we take a look at the research on CBD and nausea. We also include a list of our top CBD picks for nausea and some pointers on how to shop for this kind of CBD product.

The cannabis plant contains many active compounds called cannabinoids, including CBD. Tetrahydrocannabinol (THC) is another well-known cannabinoid. But, unlike THC, CBD isn’t intoxicating, so you won’t get high from ingesting it.

The three forms of CBD are:

  • Isolate. This is pure CBD. Isolate products contain no other compounds from the cannabis plant. Just CBD.
  • Broad-spectrum. Broad-spectrum products contain some cannabinoids and other cannabis plant compounds, but no THC.
  • Full-spectrum. Full-spectrum CBD contains the whole kitchen sink of cannabis plant compounds including CBD, tiny amounts of THC, terpenes, and flavonoids — the latter give cannabis its pungent flavor and aroma.

Preliminary research suggests that CBD may help with:

However, it’s important to keep in mind that more research needs to be done — especially large human studies — before we can say for sure what CBD’s risks and benefits are.

A lot of the research on CBD and nausea focuses on its benefits for people with cancer. Nausea and vomiting are often a side effect of chemotherapy treatment.

Animal studies suggest that CBD might help quell nausea because it interacts with serotonin receptors. This hormone influences how you feel — namely, your mood and general sense of well-being.

While CBD may play a part in reducing nausea, researchers conclude that THC, the main psychoactive component of cannabis, does more of the heavy lifting when it comes to helping with nausea and vomiting.

Human studies also show that a combination of CBD and THC may provide relief from nausea in people going through chemotherapy.

Chemotherapy can also affect your appetite, and cannabinoids can help with this, too.

Currently, there are two synthetic cannabis-derived drugs approved by the Food and Drug Administration (FDA) for chemotherapy-related nausea and vomiting. They are Nabilone and Dronabinol.

Because the research shows that THC is probably more effective at reducing nausea than CBD, full-spectrum CBD products are your best CBD option for quelling queasiness.

Full-spectrum CBD has all the beneficial, naturally occurring cannabinoids from the cannabis plant, including teeny tiny amounts of THC — up to 0.3 percent in federally legal products.

When choosing a CBD product, you’ll want to select a form of CBD that appeals to you. If you’re feeling nauseous, you won’t want to take something that makes you want to gag.

For instance, if you’re having trouble keeping food down, opt for a tincture or oil that you place under your tongue rather than a flavored gummy.

Pros

  • Limited side effects. Unlike prescription medications, CBD has very few side effects.
  • Multi-use. CBD may also be beneficial for other issues, particularly those related to cancer or cancer treatment, such as chronic pain.

Cons

  • Ingestion may be difficult. If you have nausea, you may find it difficult to take oral CBD products.
  • Possible appetite changes. In some people, CBD may limit appetite, which may be counterproductive in people with nausea.

There are so many CBD products out there that shopping for them is enough to give anyone a headache. Weed out the good from the bad by keeping these things in mind:

  • Potency. If you’re dealing with severe nausea, small amounts of CBD may not cut it. Look for products with more than a few milligrams of CBD per serving.
  • CBD source. CBD isolate is an excellent option if you want to stay away from THC. However, stripping away terpenes and other cannabinoids may reduce the anti-nausea effects of a CBD product. Opt for full-spectrum products over isolates. If you’re set on staying away from THC, opt for broad-spectrum CBD, which contains most cannabis plant cannabinoids but no THC.
  • Third-party testing. Look for products with a COA so you have confirmation that the CBD is free of contaminants (including heavy metals, pesticides, and molds) and is actually as potent as the company claims.
  • Ingredients. Choose CBD products made with organic, U.S.-grown hemp whenever possible. When buying CBD specifically for nausea, you might like a product with added peppermint or ginger flavorings to help reduce queasiness and improve the taste.

This depends a bit on the form of CBD you’ve chosen.

You can take tinctures and oils by mouth using a dropper. Just place them under your tongue and hold it there for a few seconds before swallowing. Swallow capsules whole as you would any other pill, or chew on gummies.

Most companies give you an idea of how much or how often to take their CBD product. If you’re new to taking CBD, though, it’s best to start with the smallest dose.

Research finds that most people will have no trouble when taking CBD, but there is a chance you may experience side effects, including:

  • diarrhea
  • fatigue
  • weight changes
  • appetite changes

Taking CBD alongside a high-fat meal may increase the risk of side effects, according to some research .

Before you take CBD for nausea, talk to your healthcare provider. CBD can interact with certain medications, so it’s a good idea to be open and honest with your physician.

It’s also worth having a chat with your doctor if you’re interested in trying CBD for nausea and vomiting due to chemotherapy. There may be other medications or strategies you can try first.

Before you try CBD for nausea, talk with a doctor.

“Nausea is not normal for healthy humans and it should not be ignored,” says Jordan Tishler, MD, faculty at Harvard Medical School, president of the Association of Cannabinoid Specialists, and CEO and CMO of inhaleMD, a patient-focused clinical practice.

“Anyone with ongoing nausea should seek medical attention,” he says. “Only after a thorough evaluation should any form of treatment be contemplated.”

Talk with your doctor about any medications you currently take — both prescription and over the counter. CBD may interact with some medications and cause adverse effects, such as diarrhea and fatigue, in some people.

“It’s very important to note that CBD, more so than THC, can interact with common medications like warfarin, Plavix, and even Claritin,” Tishler says. These interactions can cause life threatening complications.

Can CBD increase your appetite?

Yes. One of the potential side effects of taking CBD is a change in appetite. However, in some cases, it can also decrease your appetite.

Can CBD help with morning sickness?

Possibly, but there’s not enough evidence specifically on morning sickness to say for sure whether CBD is an appropriate and safe treatment.

One very small study involving four pregnant people found that cannabis may help with morning sickness. However, most experts advise against cannabis use during pregnancy. The FDA also advises against taking CBD while pregnant or breastfeeding.

Can CBD make you nauseous?

Yes. Nausea is a possible side effect of CBD.

Is CBD good for nausea?

While some people find relief from nausea with CBD products, a definitive answer needs further clinical research.

“At this time, the use of CBD for nausea in humans is not appropriate,” Tishler says. “While we are awaiting more human data, I do not recommend CBD products to patients.”

What CBD is best for nausea?

THC may work better for reducing nausea, so full-spectrum CBD oil may the best option for nausea relief.

Since further research on CBD is needed, not all doctors recommend CBD for relief from nausea.

How fast does CBD oil work for nausea?

Some people begin to feel the effects of CBD oil within 15 minutes.

There’s some evidence that CBD might help with nausea, but the current research is limited. THC may be more helpful.

That said, some people use CBD to successfully manage nausea.

If you’ve tried other treatments, haven’t found relief for your nausea, and want to try CBD, opt for full-spectrum products made with organic U.S.-grown hemp that have been tested by a third-party lab.

Is CBD legal? The 2018 Farm Bill removed hemp from the legal definition of marijuana in the Controlled Substances Act. This made some hemp-derived CBD products with less than 0.3% THC legal at the federal level. However, CBD products containing more than 0.3% THC still fall under the legal definition of marijuana, making them illegal at the federal level. Some states have legalized CBD, so be sure to check state laws, especially when traveling. Also, keep in mind that the FDA has not approved nonprescription CBD products, and some products may be inaccurately labeled.
