Toronto, Canada: Young and middle-aged adults who consume cannabis are no less likely than non-users to engage in daily physical activity, according to data published in the journal Cannabis and Cannabinoid Research.
Canadian researchers assessed physical activity in a cohort of 4,666 US adults ages 18 to 59 years old. Subjects wore a portable accelerometer that tracked participant’s daily activity levels. Researchers collected data for a minimum of four days.
Investigators reported that cannabis consumers were slightly more likely than non-users to engage in light physical activity. Researchers reported no differences between the two groups with respect to median daily sedentary time, time spent engaging in vigorous physical exercise, or sleeping.
“Recent cannabis use in young to midlife adults was not associated with accelerometer-measured sedentary or MVPA [moderate-to-vigorous physical activity] time, but it was associated with a marginal increase in LPA [light physical activity] time,” the study’s authors concluded. “Our findings provide evidence against existing concerns that cannabis use independently promotes sedentary behavior and decreases physical activity.
“This study provides useful insight into the association between cannabis use and physical activity, which may help inform clinicians and prescribers with patient counseling, patients and their lifestyle choices, as well as policy makers around public health resource allocations.”
The findings are consistent with those of several prior studies “challenging the stereotype that marijuana … users are less active than their non-using counterparts.” Among those age 60 and older, marijuana use has been associated with increased exercise frequency.
