Among cannabis-using adults 50+, 20% reported driving within 2 hours of consumption, with daily users, men, and those using for mental health reasons at highest risk.
Older cannabis users who drive, geriatricians, traffic safety officials, and aging researchers
What the researchers found
20.2% of past-year cannabis users aged 50+ reported driving within 2 hours of consumption; daily use (OR=3.31), male sex (OR=1.72), and mental health motives (OR=1.93) were independent predictors of cannabis-impaired driving.
Why it matters
Cannabis use among older adults is surging, and this population faces unique driving risks from age-related cognitive changes compounded by cannabis impairment — yet they're rarely the focus of prevention efforts.
The numbers in context
3,379 total; 729 (21.4%) past-year cannabis users; 20.2% reported driving after use; 64.8% aged 50-64; 35.2% 65+; daily use OR=3.31; mental health motives OR=1.93; male OR=1.72.
How the study worked
Cross-sectional analysis of a nationally representative survey of adults 50+ (N=3,379, with 729 past-year cannabis users), examining correlates of self-reported driving within 2 hours of cannabis consumption.
What this study cannot tell us
Self-reported driving behavior likely underestimates true prevalence; cross-sectional design; 2-hour window is arbitrary; doesn't assess actual impairment or crash risk.
How to read the evidence
Nationally representative survey with appropriate regression analysis, but self-reported driving behavior and cross-sectional design limit conclusions.
When this study was published
Published in 2026, addressing the understudied intersection of aging, cannabis use, and driving safety.
The bigger picture
With baby boomers driving cannabis market growth, the intersection of aging, cannabis use, and driving safety represents an emerging public health challenge that current prevention programs largely ignore.
Questions still open
- At what THC dose and timing are older adults actually impaired for driving? Should age-specific cannabis-driving education be developed for 50+ users?
Common questions
Do older adults drive after using cannabis?
Who is most likely to drive after using cannabis?
