Among over 4,400 U.S. adults, recreational physical activity was associated with less cannabis use, while sedentary behavior and work-related physical activity were linked to more cannabis use.
Cannabis users interested in lifestyle factors, exercise enthusiasts, public health professionals, and anyone curious about the activity-substance use connection.
What the researchers found
After adjusting for covariates, sedentary behavior was positively associated with cannabis use (OR=1.365), as were work physical activity (OR=1.135) and commuting activity (OR=1.209). Recreational physical activity was the only type negatively associated with cannabis use (OR=0.858), though this association was attenuated after adjusting for all covariates.
Why it matters
The finding that recreational exercise specifically (not work-related activity) is linked to less cannabis use suggests that enjoyable physical activity may serve as an alternative coping mechanism, while sedentary lifestyles may create conditions more favorable to substance use.
The numbers in context
4,428 participants aged 20-60. Sedentary behavior OR=1.365 (p<.001). Work activity OR=1.135 (p<.001). Commuting activity OR=1.209 (p<.001). Recreational activity OR=0.858 (unadjusted model, p<.05). All adjusted for covariates.
How the study worked
Cross-sectional analysis of 4,428 adults aged 20-60 from NHANES (2013-2018). Physical activity assessed via the Global Physical Activity Questionnaire (GPAQ). Cannabis use assessed via drug use questionnaire. Binary logistic regression with covariate adjustment.
What this study cannot tell us
Cross-sectional design cannot establish causation. Cannabis users who exercise recreationally may differ in unmeasured ways. Self-reported physical activity and cannabis use. GPAQ may not capture all activity types. 2013-2018 data precedes recent legalization expansion.
How to read the evidence
Large nationally representative sample with validated activity measure, but cross-sectional design limits causal inference.
When this study was published
Published in 2026 using 2013-2018 NHANES data.
The bigger picture
This adds nuance to the exercise-substance use relationship. Not all physical activity is equal — recreational exercise chosen for enjoyment appears protective, while obligatory work activity does not. This has implications for prevention programs that promote exercise as a substance use intervention.
Questions still open
- Would exercise-based interventions reduce cannabis use? Why is work physical activity associated with more cannabis use — job stress? Could promoting recreational exercise be part of cannabis harm reduction?
Common questions
Does exercise reduce cannabis use?
Why is work physical activity linked to MORE cannabis use?
