A recent study by the Minnesota Office of Cannabis Management (OCM) has indicated that medical marijuana can alleviate pain, nausea, vomiting, anxiety, and depression in cancer patients while also enhancing sleep quality. This research is described as one of the most extensive analyses of medical cannabis treatment to date, involving 6,621 participants in the state’s medical cannabis program.

Participants assessed the severity of their symptoms at enrollment and again during the treatment process. Among the 82 percent of cancer patients who reported experiencing moderate to severe pain, 30 percent noted at least a 30 percent decrease in pain levels within four months of starting medical marijuana treatment. Over half of these patients sustained this improvement for an additional four months.
Similarly, over half of the participants initially reported nausea, with more than a quarter experiencing vomiting. After four months, 40 percent of those with nausea reported a reduction of 30 percent or more, while 47 percent experienced similar relief from vomiting. Notably, these improvements were maintained by 65 percent and 74 percent of the respective groups in the following four months.
Dr. Grace Christensen, a senior research analyst at OCM, stated that the results suggest promising potential for cannabis in managing symptoms associated with cancer and its treatment, emphasizing that even minor relief can significantly enhance patients’ quality of life.
Additionally, 38 percent of patients who struggled with appetite reported a 30 percent or greater improvement within four months, with 63 percent maintaining this benefit afterward. The study also highlighted improvements in anxiety, depression, sleep disturbances, and fatigue among patients, with significant portions reporting reductions in their symptom scores.
Only 15 percent of participants reported adverse side effects related to medical cannabis use, with the majority classified as mild. Dr. Dylan Zylla, an oncologist and medical director at the HealthPartners Cancer Research Center, noted that cannabis treatment appears to be relatively safe and expressed a preference for starting patients on low doses of THC to mitigate risks.
The findings align with previous research indicating that medical marijuana has positive effects on patients with chronic pain and sleep apnea. Additional studies have shown that cannabis can provide substantial benefits for cancer-related symptoms, such as pain relief and improved emotional well-being, while some evidence suggests potential anti-cancer effects of cannabinoids.
These findings contribute to a growing body of evidence supporting the therapeutic use of medical marijuana for cancer patients.
