The Boston Globe reports the goers "were taken to local hospitals from the TD Garden tonight after consuming a dangerous substance, according to an EMS worker." Supposedly 50 more people were treated on the scene.
Thankfully, there are no fatalities, but this isn't a first-time incident for the Swedish DJ performer.
According to Jennifer Smith and Todd Feathers in "Dozens hospitalized at TD Garden concert," Toronto had the same problem recently. In that case, The Toronto Star stated that at least 29 people were hospitalized for alcohol and/or drug-related illnesses.
Boston's ABC affiliate, WCVB, lists the breakdown of patients from the concert in Steven Yablonski's "Dozens brought to hospitals after TD Garden incident."
Tufts Medical Center said at least 10 patients with non-life threatening injuries showed up while Massachusetts General Hospital stated 12 patients with non-life threatening injuries showed up. MGH lists the patients as being between 16-19 years olds. Also, Boston EMS declared a Level 2 Mass Casualty Incident where the level represents number of patients needing attention.
"Officials said a combination of drug use, drinking and the heat were to blame."
Early reports indicated up to 80 people were transported to the medical centers but numbers quickly decreased.
Information is still unfolding but Boston.com announced a checkpoint was set up at the corner of Beverly and Causeway Street in post "Dozens Hospitalized After TD Garden Concert" by Roberto Scalese.

Interestingly the last tweet submitted by the official TD Garden account is about the concert but not the mass causality incident.
