Older cannabis users showed higher fall risk, worse balance, and slower walking than non-users
Among 16 older adults, chronic cannabis users showed higher fall risk, worse one-leg balance, and slower gait speed compared to age- and sex-matched non-users, though cognitive function did not differ.
Quick Facts
What This Study Found
Cannabis-using older adults showed higher fall risk scores, poorer one-leg standing balance, and slower gait speed compared to matched non-users. No significant differences in cognitive function were found between groups.
Key Numbers
Total participants: 16. Cannabis users: 8. Non-users: 8. Age and sex matched. Higher fall risk, worse one-leg balance, and slower gait in users. No cognitive function difference.
How They Did This
Cross-sectional comparison of 8 older chronic cannabis users and 8 age- and sex-matched non-users. Assessed fall risk, one-leg standing balance, gait speed, and cognitive function using standardized tests.
Why This Research Matters
Falls are a leading cause of injury and death among older adults. If cannabis use exacerbates age-related balance and gait decline, this has significant clinical implications as cannabis use grows among seniors.
The Bigger Picture
With cannabis use increasing most rapidly among older adults, understanding how it interacts with age-related physical decline is critical for preventing falls and maintaining independence.
What This Study Doesn't Tell Us
Very small sample (n=16). Cross-sectional design cannot determine if cannabis caused the impairments. No control for pre-existing conditions or medications. Cannot assess acute vs. chronic effects.
Questions This Raises
- ?Is the fall risk from cannabis chronic or only during acute intoxication?
- ?Would CBD-dominant products carry the same risk?
- ?Could dosage adjustments mitigate balance effects in seniors?

What do these levels mean? →Frequently Asked Questions
Does cannabis increase fall risk in older adults?
This small study found chronic cannabis users had higher fall risk scores, worse balance, and slower gait than matched non-users, but the sample was too small to draw definitive conclusions.
Did cannabis affect thinking ability in older adults?
No. Despite the physical function differences, cognitive test scores did not significantly differ between cannabis users and non-users in this study.
