A freshman at Fairfield University has been charged with a series of drug violations after police said he was advertising sales of illegal drugs using business cards.

James Torpey, 18, of Roxbury, Mass., was charged Wednesday with possession of marijuana with intent to sell, possession of marijuana, possession within 1,500 feet of a school and possession of drug paraphernalia after police executed a search warrant at his dormitory room on campus.

According to detectives, police received a tip from the university's security staff that Torpey was selling marijuana to other students and promoting himself with business cards that read, "Bean Marijuana, Inc." and included his cell phone number.

An informant made "numerous" purchases from Torpey, police said.

Torpey was released on a promise to appear Dec. 12 in Bridgeport Superior Court.
