Washington (CNN) — Authorities have arrested two Georgetown University students and another person in connection to a suspected drug lab found inside a dormitory Saturday morning, D.C. Metro police said.

The three males, each at least 18, face charges of possession of drug paraphernalia, said Officer Hugh Carew, a spokesman for the police department. The third individual was a campus visitor. None were identified.

Police said that shortly before 6 a.m., they received a call about a foul odor at Georgetown’s Harbin Hall.

Initially, police thought the lab was for producing meth, but later said it was for making Dimethyltryptamine, a hallucinogenic drug commonly known as DMT.

DMT is an illegal substance, and the charges against the three men remain the same, Carew said.
