A federally funded study reveals that marijuana users tend to be more physically active on days they consume cannabis—challenging the long-standing “lazy stoner” stereotype. However, the research also finds they drink alcohol more heavily and smoke more cigarettes on those same days.
Key Findings from the Study
Published in the journal Addictive Behaviors, the study analyzed data from a four-week nationwide survey of 98 adult cannabis users. Participants logged their daily habits via smartphone surveys, tracking behaviors such as moderate-to-vigorous physical activity (MVPA) and substance use.
Researchers from multiple U.S. institutions—including the University of Oklahoma Health Sciences, the University of Texas School of Public Health, and the University of Michigan—found that cannabis consumption correlated with increased physical activity. However, it also coincided with higher alcohol intake and tobacco use.
Cannabis and Physical Activity: A Surprising Link
The study did not compare marijuana users to non-users but supported previous findings that cannabis consumers tend to engage in more physical activity.
“Daily cannabis use was positively associated with daily MVPA,” the researchers wrote, noting that past studies have suggested marijuana users log more weekly exercise than non-users. However, conflicting research has indicated that long-term cannabis users may engage in less recreational physical activity than those who have never used the substance.
Why Does Cannabis Use Align with Increased Activity?
While the study does not establish a direct cause-and-effect relationship, it suggests that cannabis might enhance enjoyment and motivation for physical activity.
“It may be that cannabis use increased [physical activity] enjoyment and/or subsequent feelings of psychological reward,” the authors explained. The paper also cites theories that cannabis could enhance exercise recovery and activate the endocannabinoid and dopaminergic systems, increasing feelings of pleasure from physical activity.
Cannabis, Alcohol, and Cigarettes: A Shared Reward System?
The study also found that cannabis users tended to drink more alcohol and smoke more cigarettes on days they consumed marijuana. Researchers speculate that the same psychological reward mechanisms influencing physical activity might also drive these behaviors.
Previous research has suggested that simultaneous alcohol and marijuana use can intensify the effects of intoxication. This could explain why some users are drawn to multiple substances on the same day.
Final Thoughts
The findings add nuance to public perceptions of cannabis users. While the stereotype of the inactive, unmotivated stoner may not hold up, the study highlights potential health trade-offs—such as increased alcohol and tobacco consumption. Further research is needed to understand these complex behavioral links and their long-term implications.
