As cannabis is legalized in more states across the country, new research points to the negative side effects of partaking too much.
Researchers from the University of Colorado Anschutz Medical Campus looked into the impact of recent and lifetime cannabis use on brain function during cognitive tasks.

"Heavy users" in the study included those who used cannabis more than 1,000 times over their lifetime.
