DENVER (KDVR) — The Director for External Communications for Denver Public Schools says five students were treated for medical issues that may have been associated with drugs in the school parking lot at John F. Kennedy High School.

It happened in the student parking lot at 2855 S. Lamar St. in Denver on Thursday morning.

DPS said one of the students was taken to the hospital. The other four students were treated and released to family members.

In a newsletter released by Principal Tiffany Almon on Dec. 2, the family of the student hospitalized shared that the student was listed as in stable condition.

Following the incident, the school announced changes.

“We have increased supervision in our student parking lot and are prohibiting students from hanging out in their cars while on school grounds,” Almon shared.
