Pain, Depression, and Functional Outcomes Among Older Adults Who Use Cannabis or Opioid Analgesics for Chronic Pain Conditions
Verified on PubMed Oxford CEBM Level 2B: Clinical Cohort Study
A 2026 observational study in Clinical Gerontologist tested opioid in depression. It made no difference in physical disability, but cannabis use was linked to more pain interference and depression, while opioid use was linked to more pain intensity. This study suggests that for older adults, cannabis use may be linked to worse pain interference and.
In plain language
Study overview
This study looked at older adults with chronic pain who use cannabis or opioids. It tracked their pain levels, ability to function, and feelings of depression over time. The study found that cannabis users had more pain and felt more depressed, while opioid users had more pain but no change in depression or function.
Findings
It made no difference in physical disability, but cannabis use was linked to more pain interference and depression, while opioid use was linked to more pain intensity. The results suggest that cannabis may not be as helpful for pain and could worsen mood.

The deeper readScientific analysis
Objectives: To estimate the proportions of older adults with chronic, non-cancer pain (CNCP) who use cannabis or prescription opioids, and their pain, function, and measures of depression over time. Methods: Longitudinal, observational secondary analysis of older adults enrolled in the Oregon Center for Aging and Technology study with pain for >=12 weeks. Predictors were cannabis and opioid use at weekly intervals. Outcomes were weekly pain intensity, pain interference, feeling blue, physical limitations, and annual Geriatric Depression Scale scores. Results: About 353 participants met criteria with 5% using cannabis and 11% opioids. After controlling for confounders, cannabis use was associated with more pain interference and depression symptoms over time. Opioid use was associated with more pain intensity and interference. Conclusions: Cannabis was associated with more pain interference and symptoms of depression. Findings were limited by a small sample. Longitudinal data with reliable measures are needed.

Limitations the authors noted
Observational secondary analysis; causal direction cannot be established and reverse causation is possible. Very small cannabis-using subgroup (18 participants) and unknown frequency of use limit interpretation. Cannabis and opioid exposure recorded as binary, time-variant variables without potency, dose, route, or frequency data. Self-reported medication changes and stigma may cause under-reporting of cannabis use. Specific pain diagnoses and depression histories were not identified; findings may not generalize. Sample was 94.1% White, computer-using, and drawn from a single state; marital status (44.2% missing) was dropped from models. Missing Geriatric Depression Scale data for 206 of 961 observations (17.7%). Lack of control for other variables; no power calculation; authors state results should be interpreted with caution.
In practice
Why this matters
This study suggests that for older adults, cannabis use may be linked to worse pain interference and mood compared to opioids, prompting clinicians to reconsider its role in managing chronic pain in this population.
