Emergency-room visits related to cannabis use in Colorado—the first U.S. state to completely legalize its use—have tripled at one of the state’s largest hospitals over the past few years, according to a study published on March 25.
The study published in the Annals of Internal Medicine examined 9,973 emergency department visits attributed to both inhaled and edible cannabis between 2012 and 2016 at the University of Colorado hospital in Aurora.
