Medical Cannabis for Nausea and Appetite: Recent Research

Recent Research on Medical Cannabis for Nausea and Appetite

Recent peer-reviewed research from PubMed explores the potential role of medical cannabis in managing nausea and appetite. While these studies offer insights, it's important to remember that science is still evolving. Always talk with a licensed physician about what’s right for you.

Medical Cannabis and Therapeutic Use

A 2025 review in JAMA found that roughly 27% of adults in the U.S. and Canada have used cannabis for medical purposes, while about 10.5% of the U.S. population uses cannabidiol (CBD) for therapeutic reasons. The U.S. Food and Drug Administration (FDA) has approved cannabinoids for specific conditions, including nausea and vomiting caused by chemotherapy, as well as appetite loss in HIV/AIDS patients.

This study also highlighted that while cannabis-based treatments show promise, more research is needed to fully understand their benefits and risks. If you're considering medical cannabis, discussing it with your doctor is key.

Cannabinoids for Chronic Pain and Related Symptoms

Another 2025 study in the Annals of Internal Medicine reviewed the use of cannabinoids for chronic pain, which often coexists with nausea and appetite issues. The research categorized cannabinoids by their tetrahydrocannabinol (THC)-to-CBD ratio (high, comparable, or low), their source (synthetic, purified, or extracted), and how they’re administered.

While the study noted some potential benefits for pain management, it also emphasized that the evidence is still uncertain. More high-quality clinical trials are needed to determine the safety and effectiveness of cannabinoids for these symptoms.

Cannabis and Chemotherapy-Induced Nausea

Chemotherapy often causes long-term cognitive impairments (CRCI) in cancer survivors, which can include nausea and appetite loss. A 2025 study in Cancer Letters found that cannabidiol (CBD) may help reduce these side effects by targeting neuroinflammatory and neurodegenerative pathways.

The researchers suggested that CBD could be a valuable tool in managing CRCI, though more clinical studies are needed to confirm these findings. If you or a loved one is undergoing chemotherapy, discussing cannabis-based treatments with an oncologist is important.

Gastroparesis and Nausea Management

Gastroparesis—a condition causing delayed stomach emptying—can lead to chronic nausea and vomiting. A 2025 review in JAMA found that gastroparesis affects about 21.5 per 100,000 people in the U.S. and is more common in women.

While the study didn’t directly address cannabis as a treatment, it noted that managing symptoms like nausea often requires a multidisciplinary approach. Some patients find relief with medical cannabis, but it’s crucial to work with a healthcare provider to find the best treatment plan.

Medical Cannabis and Anesthesia Considerations

A 2025 study in Minerva Anestesiologica explored how medical cannabis interacts with anesthesia, which can be relevant for patients managing nausea and appetite issues. The research noted that THC and CBD interact with CB1 and CB2 receptors, affecting cardiovascular, respiratory, and neurological systems.

The study suggested that chronic or high-dose cannabis use could influence anesthetic requirements and perioperative risks. If you use medical cannabis and are preparing for surgery, discussing this with your anesthesiologist is essential.

The Endocannabinoid System in Psychiatric Disorders

Finally, a 2025 study in Neuroscience Bulletin examined the role of the endocannabinoid system (ECS) in psychiatric disorders, which can sometimes include symptoms like nausea and appetite loss. The ECS influences pain perception, cognition, appetite, and behavior.

The researchers suggested that imaging the ECS could provide insights into underlying mechanisms and improve clinical management. While this doesn’t directly address cannabis use, it highlights the ECS’s importance in overall health.

Talk With Your Physician

While these studies offer promising insights, medical cannabis is not a one-size-fits-all solution. Always consult a licensed physician to discuss your individual needs and potential risks.
