Two Baltimore County teen-agers were released on their own recognizance after they were charged with drug-related offenses Friday.

Tfc. Leonard A. Lucas said he found two 18-year-old women in a car at the rear of Carroll Community College in Westminster about midnight Thursday, smelled the odor of marijuana and saw a smoking pipe in the open glove compartment of a 1982 Chevrolet.

Mary Kathleen Roerty of the 9500 block of Axehead Court in Randallstown and Kelly Lynn Duvall of the 9200 block of Wright Mills Road in Woodstock were charged with possession of marijuana. Both were released after a hearing before a court commissioner.
