UPDATE: TMZ reported that ecstasy played a major role in the hospitalization spike at Avicii's Boston concert. Law enforcement sources said that some of the concertgoers were high on ecstasy and many of those taken to the ER were "severely dehydrated," a common side effect of the drug.
EARLIER: At least 36 people were hospitalized after Avicii performed at Boston's TD Garden on Wednesday, June 25. According to reports, dozens more were treated on the scene at the EDM concert.
Boston.com reported that, at one point, medical services on site declared a Phase 2 Mass Casualty Incident, which occurs when more than 30 people are involved. There were no fatalities.
"Fortunately no one was seriously injured. Mostly underaged kids involved in alcohol and or some illicit drugs," Boston EMS deputy superintendent Mike Bosse told the Boston Herald, also noting that many of the people in attendance were already intoxicated upon arrival. Reports confirm that those who were hospitalized ranged from 16 years old to 25. Bosse also confirmed 50 people were treated on site.
Other reports that quote concertgoers suggest high usage of Molly and alcohol. A spokeswoman for concert promoter Live Nation, Jacqueline Peterson, said in a statement that early reports indicated that a majority of those who were hospitalized "were people outside the venue who were too impaired to be allowed inside."
This is just the latest report of medical scares at an EDM concert. Last weekend, two people died at Las Vegas electronic music festival, Electric Daisy Carnival, at which Avicii also performed. The victims' cause of death has yet to be confirmed, but police said that almost 800 people were treated for medical conditions during the three-day festival.
Avicii, also known as Tim Bergling, tweeted his condolences after the show:
