“Denver Public Schools is very concerned about the apparent increase in marijuana use by students,” a district statement says, according to Colorado Public Radio.

The district has increased its intervention and counseling services for students.

“Those efforts were recently expanded at the middle school level through the hiring of a substance abuse prevention supervisor.”

There are 185 class days during the 2014-15 school year, according to the district’s website, which equals 1.56 arrests per school day.
