Cops: Wesleyan Students Took Bad Batch of MDMA

A bad batch of MDMA is believed to have caused overdoses that sent 11 students to the hospital, according to police in Middletown, Conn. Police say at least two of the Wesleyan University students are in critical condition after taking the drug—also known as Molly—on Saturday night, reports the Hartford Courant.

The university says seven of the students were transported to the hospital while another four walked in for treatment, and campus officials are "conducting well-being checks in some areas," NBC reports. Police say they're working with the state forensics lab to determine the source of the drug. (More MDMA stories.)
