BOSTON (WHDH) -
TD Garden has been cited following a mass medical emergency that included more than 80 people during the Avicii concert Wednesday night.
50 of those people were treated by paramedics at the Garden. Another 36 people had to be taken to local hospitals.
"There was a lot of drinking and some drugs. It was really hot in there," a concert-goer said.
Boston Police issued citations for intoxicated patrons and patrons consuming drugs on the premises.
The Suffolk County District Attorney's office said that three men were arrested near the TD Garden. Each is facing drug charges and is expected to be arraigned Thursday. None have been linked to the hospitalizations.
A video posted online shows a person being looked at by officers.
"Everyone was having a good time but then when we left there was ambulances and police officers," a concert-goer said
Boston EMS says none of the patients they saw were in serious condition, but dozens of ambulances were called to the concert shortly after it began at 8 p.m.
"Mostly heat and alcohol related symptoms. There was a lot of underage drinking tonight and some illicit drugs. However, we can't identify anything specific," Boston EMS Deputy Superintendent Michael Bosse said.
By the time the show ended at 11 p.m. a staging area had been set up on Causeway Street.
"A good amount of people were under the influence of drugs. A lot of ambulances showed up to take away people who were not okay to stay at the concert," a concert-goer said.
Concert promoter Live Nation says most of the people taken to the hospital were stopped before going in to the concert.
Avicii, a Swedish disc jockey, posted a tweet online saying he hopes everyone is okay.
Just hearing the awful news abt tonight. Its a terrible thing, I rly hope everyone is ok! My thoughts go to those affected & their families.

Officials say heavy alcohol consumption at a concert like this one is all too common.
"When you have this type of a concert, this techno-rave type thing, we kind of know it may be coming," Bosse said.
"People go overboard, so I think this is what they did, they just went overboard," a concert-goer said.
Boston EMS said most of the patients they saw were between the ages of 16 and 25-years-old and no injuries were serious.
TD Garden released a statement, saying that it is taking the incident "very seriously."
"We implemented increased precautions such as restricted alcohol sales, additional security and provided two cooling off areas for guests, in addition to the building maintained at normal temperature," the statement said.
Commissioner Evans and Mayor Walsh are looking to meet with TD Garden officials next week to discuss the incidents.
“If the young people were allowed in there intoxicated that should not be happening. It’s my understanding they did detain some kids going in and call their parents; I don’t know if it’s before or after. It’s hard to say be prepared, kids shouldn’t be drinking alcohol,” Mayor Walsh said.
Officials say the TD Garden has been cited five or six times in the past few years for various issues. They say that number isn't unusual for an entertainment venue of any size.
