Does cannabis help with nausea? Yes, for some people, cannabis and certain cannabinoids can reduce nausea. The strongest evidence is for chemotherapy-induced nausea and vomiting, where prescription cannabinoids such as dronabinol and nabilone are FDA-approved. For other types of nausea, research is more mixed.
Cannabis for Nausea Dosage Guide
How Cannabinoids Reduce Nausea
The body has an endocannabinoid system that helps regulate nausea and vomiting. THC, the main psychoactive compound in cannabis, binds to CB1 receptors in the brain and digestive tract. This interaction can suppress the nausea reflex. CBD may also affect nausea, but the evidence for CBD alone is weaker and less consistent.
What the Research Shows
- Chemotherapy-induced nausea and vomiting: Strong evidence. A 2017 report from the National Academies of Sciences, Engineering, and Medicine found substantial evidence that cannabis and cannabinoids are effective for this condition.
- Prescription cannabinoids: The FDA has approved dronabinol (Marinol) and nabilone (Cesamet) for chemotherapy-induced nausea and vomiting that has not responded to other treatments.
- Other causes: Some small studies suggest cannabis may help with nausea from HIV/AIDS, chronic pain, or other conditions. However, these uses are not as well studied, and results vary.
- CBD: Early research suggests CBD may have anti-nausea effects, but more human trials are needed.
Forms of Cannabis for Nausea
- Inhalation: Smoking or vaping provides rapid relief, often within minutes. Effects fade in 1 to 3 hours.
- Oral: Edibles, capsules, and tinctures take 30 to 90 minutes to work, but effects last longer, up to 6 to 8 hours.
- Prescription cannabinoids: Dronabinol and nabilone are synthetic forms available as capsules. They are taken by mouth and prescribed by a doctor.
What to Consider
- Side effects: Drowsiness, dizziness, dry mouth, impaired coordination, and memory problems. Some people may experience anxiety or paranoia.
- Dependence: Regular cannabis use can lead to dependence in some people.
- Drug interactions: Cannabis can interact with other medications, including blood thinners and antidepressants.
- Legal status: In the US, cannabis laws vary by state. Eden Cannabis operates legally in its jurisdiction. Check local laws before use.
When to See a Doctor
Nausea that lasts for days, comes with severe vomiting, weight loss, or signs of dehydration needs medical attention. If you are considering cannabis for nausea, talk with your healthcare provider. They can help you weigh benefits and risks, especially if you take other medications or have underlying health conditions.
