Adventure Land, an EDM show at Quassy Amusement Park in Middlebury, Conn., was shut down after at least seven people were treated for overdoses for allegedly ingesting the drug 2-CP.
Around 10:30 p.m. four people simultaneously "dropped" from suspected overdoses, with one young male allegedly losing his pulse and needing to be revived via defibrillator.
The overdoses are reminiscent of the deaths of two people from club drug Molly at the Electric Zoo music festival, which was also canceled.
So what is 2-CP? Some people are reporting it as being a "new" street drug.
The hallucinogenic drug, which can create visions for an entire day, is considered dangerous because it overheats the body and has a very slow onset of 3 to 5 hours.
