DEDHAM, MA—Elyssa Schuster, 16, swore Monday that she will never again experiment with marijuana after coming home to "obviously baked" parents Harold and Judy Saturday night. "I used to think smoking pot made you look cool, but, boy, was I wrong," Schuster said. "Dad got all paranoid about the mortgage rate while Mom spent an hour giggling about how dusty the ceiling fan was. It was so sad and depressing." Schuster said she was thankful to be scared straight before she made a fool of herself again.
