At least 36 people, many of whom were minors, had to be taken to the hospital after consuming alcohol and illicit drugs at an Avicii concert in Boston on Wednesday night. At least seven ambulances, including an emergency trailer, showed up to the arena to tend to the victims. According to an EMS worker, there were no fatalities, just minor injuries. Boston EMS said most of the patients they saw were between the ages of 16 and 25 years old. Last week, at an Avicii concert in Toronto, 29 people were hospitalized.
