Five people were hospitalized in Evanston Saturday afternoon after they became ill from eating brownies that officials suspect were laced with marijuana.
The Chicago Tribune reports that Evanston Fire Division Chief Tom Janetske says ambulances were called to an apartment in the 1700 block of Chicago Avenue around 4 p.m. to transport the victims, who he said were all at least 19 years old.
It wasn't immediately known whether the victims were Northwestern University students. The school was holding its annual Dillo Day festival on the lakefront Saturday, an event that has led to complaints from neighbors about excessive drinking and other roudy behavior in the past.
In a similar incident last February, a half-dozen students at Evanston Township High School were hospitalized after they ate home-made brownies laced with marijuana.
One student was charged as a juvenile with drug possession in connection with that incident.
