Most Americans don't get anywhere near enough exercise - for all kinds of reasons. Some researchers have wondered wheter a rise in the use of marijuana is one of them.

The stereotype is the kid on the couch eating Doritos, not being physically active," says Angela Bryan, a professor of psychology and neuroscience at the University of Colorado Boulder. As marijuana is becoming leglized in more states acorss the county, "if that was the impac tof cannabis on physical activity, that would be a big problem"

There isn't much scientific literature on the relationship between between cannabis and exercise. But some reasearch suggest that people who use marijuana actually tend to have lower body mass indexes and risks for obesity than people who don't use it, and a 2015 review article from Bryans' lab found that cannabis is linked to greater felling of motivation and enjoyment about exercise, potentially by activating brain pathways involved in feeling of reward and pain response.

Now, in new research published in Frontiers in Public Health, Bryan and her colleagues found that many people do use weed before or after their workouts - and that those who do actually tend to exercise more than the average American.
