New York, NY — Patients hospitalized with rheumatoid arthritis (RA) who use cannabis are significantly less likely to die during their hospital stay and tend to incur lower medical expenses than those who do not use cannabis, according to a large-scale analysis published in the Baylor University Medical Center Proceedings.
The study, conducted by researchers from St. Barnabas Hospital in the Bronx, evaluated the records of over 3.3 million patients diagnosed with rheumatoid arthritis over a five-year period. Using data drawn from the National Inpatient Sample, one of the largest publicly available hospital databases in the United States, the investigators examined how cannabis use affected clinical outcomes and healthcare costs during hospitalization.
After adjusting for key demographic variables and underlying health conditions—such as age, gender, race, and comorbidities—researchers found that RA patients who reported cannabis use experienced notably better in-hospital outcomes. Specifically, cannabis use was associated with a 50 percent reduction in in-hospital mortality (odds ratio [OR]: 0.50). These patients were also less likely to suffer from co-occurring conditions commonly seen in RA populations, including depression (OR: 0.47), chronic pain (OR: 0.45), and anxiety (OR: 0.55).
In addition to the improved health outcomes, cannabis-using patients generated approximately 10 percent lower hospital-related charges per visit compared to their non-using counterparts. This suggests a potential economic benefit tied to the therapeutic use of cannabis in RA populations, possibly due to reduced complications or shorter lengths of stay.
While the findings are promising, the study’s authors urged caution in interpreting the results. “While these findings suggest potential benefits of cannabis use for symptom management, it is important to recognize that the current evidence is observational,” they noted. “Further research is warranted to explore the underlying mechanisms of these associations and to develop strategies that maximize the benefits of cannabis use while minimizing the risks.”
This study adds to a growing body of research that points to positive correlations between cannabis use and improved hospital outcomes across a range of conditions. Similar findings have been reported in patients with acute myocardial infarction (heart attack), cancer, chronic obstructive pulmonary disease (COPD), HIV, gastroparesis, pancreatitis, burn injuries, traumatic brain injuries, and other forms of severe trauma.
Rheumatoid arthritis is a chronic autoimmune disease that causes inflammation and pain in the joints and affects over 1.3 million adults in the United States. Managing RA typically involves a combination of anti-inflammatory drugs, immunosuppressants, and pain relievers. However, side effects and long-term dependency associated with some conventional treatments—particularly opioids—have driven many patients to explore alternative therapies.
According to national survey data, nearly 20 percent of arthritis patients report using cannabis products to help alleviate pain, improve sleep, reduce inflammation, and decrease their reliance on prescription medications. The plant’s active compounds, particularly THC and CBD, are believed to modulate pain and immune responses through their interaction with the body’s endocannabinoid system.
As interest in cannabis-based therapies continues to rise among patients with chronic conditions, medical professionals and policymakers face increasing pressure to better understand the drug’s therapeutic potential, risks, and long-term implications. While federal prohibition has limited large-scale clinical trials in the United States, observational studies like this one help lay the groundwork for future investigations.
Ultimately, the authors emphasized the need for more rigorous research, including randomized controlled trials, to validate these findings and determine optimal use protocols for cannabis in managing rheumatoid arthritis and other chronic illnesses.
