Grand Valley State University held a news conference Tuesday afternoon revealing four students are in the hospital stemming from a drug-related incident that occurred on the campus Monday evening.
Campus authorities didn't reveal the exact extent of the activities, but did say 4 freshman boys from the east side of Michigan were sent to Spectrum hospital, one of them to the emergency room.
"We are still trying to understand what happened, but it had an impact on them that required medical attention," said Dean of Students Bart Merkle.
The college says it's concerned first and foremost about the health of its students.
The four students caused a disturbance in the dorms on the Allendale campus Monday night. That night, a GVSU spokesperson told FOX 17 that it is suspected the students ingested something that led to erratic behavior.
The incident was reported to have occurred at the Frey Living Center around 7:15 p.m.
Multiple squad cars were on scene to assist campus police. Students who observed the events described it as chaotic.
"Glass was broken, they were running through windows, so we were just mainly worried about their conditions," said Mary Komejan, a freshman.
"It was very scary, with all the police around seeing the ambulance and the stretchers, it was just really freaky to see that happen to someone we knew," said freshman Jeffrey Visger , who lives in Stafford Living Center where part of the incident took place.
Witnesses say the students were snorting bath salts in their dorm room and taking pills, however, GVSU would not confirm the type of drugs involved.
Bath salts are a popular synthetic drug that can cause paranoia and agitation. They became illegal in Michigan in 2011, but can still be purchased on the internet.
"It's a powder-like substance that they can smoke or snort and it gives you a high just like meth. It really is a nasty drug. It was new and different, said Stephanie Vanderkooi, Health Educator with the Ottawa County Health Department.
"It is something we are seeing more with college-age adults, " she said.
