Recreational Exercise Linked to Less Cannabis Use, While Sedentary Time Links to More

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.

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.

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.

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.

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.
