Five students at Harvard Elementary School in Grand Crossing were hospitalized Wednesday after finding vape pens during a field trip, officials said

At approximately 1:50 p.m., paramedics responded to the school at 7525 S. Harvard Ave. and took five children ages 9 to 10 to an area hospital for “drug-related reasons,” according to a Chicago Fire Department spokesperson.

The students found vape pens on Tuesday's field trip and smoked them during gym class, Chicago police said. They were hospitalized after someone found them “laughing uncontrollably,” Chicago police said.

All students were listed as in good condition, authorities said.

County detectives are investigating.
