Medical Cannabis Did Not Significantly Improve Pain, Nausea, or Sleep Scores in Elderly Cancer Patients

There was no statistically significant difference in symptom scores for pain, nausea, appetite, insomnia, or anxiety before versus after medical cannabis initiation. Oil was the most common form used, followed by vape. The most common product ratios were high THC:CBD and equal parts THC:CBD.

Retrospective chart review assessing changes in numerical symptom scores reported at clinic visits before and after medical cannabis initiation in elderly cancer patients.

Despite growing use of medical cannabis for cancer symptom management, evidence in elderly patients specifically remains limited. This null result is important because it tempers expectations while also highlighting the need for larger, prospective studies in this vulnerable population.

The null result could reflect true lack of efficacy, or it could be an artifact of the retrospective design, small sample, inconsistent dosing, or the fact that elderly cancer patients often have severe symptoms resistant to many treatments. The study does confirm that elderly patients are commonly choosing THC-containing products.

Retrospective chart review with likely small sample size and inconsistent follow-up. No control group. Self-reported symptom scores. Variable products, doses, and duration of use. Selection bias in who gets prescribed medical cannabis.
