Halifax District RCMP have been called to Auburn High School after police say two students were taken to hospital after eating food that may contain illegal drugs.

Police say the students at the Cole Harbour school voluntarily ate the food. They suffered non-life threatening injuries, were treated by paramedics and transported to hospital.

Doug Hadley, a spokesman for the Halifax Regional School Board, told CBC News there were two separate incidents.

A 16-year-old male student visited the school's office about 1:20 p.m.

"They [students] had eaten approximately half an hour previous to that and there was a concern there may have been some type of drugs or something in the food he had eaten. He started to experience some medical distress," Hadley said.

Around 2:15 p.m., an 18-year-old female student fell during the school's 10-minute break between classes and appeared to be unconscious for "a period of time."

"At this point, they went into a hold and secure because they wanted students to return to class so that medical personnel would be able to come in and assist this student," Hadley said.

Hadley said the two students are expected to recover. Parents will be contacted tonight.

Police say they're investigating the source of the substance, but say it didn't come from inside the school.
