Eleven students at Wesleyan University in Connecticut are being treated after overdosing on the drug MDMA, or "Molly," Reuters reports. One student, a sophomore, is in critical condition.

Four students went directly to hospitals, a Wesleyan spokeswoman Lauren Rubenstein told Reuters. Seven others were transported separately. The sophomore in critical condition was taken to a hospital early Sunday morning.

"Several [students] are in serious condition but I can confirm that none have passed," Vice President for Student Affairs Michael Whaley wrote in an email to The Wesleyan Argus.
