Abstract: | Valerie is a typical 17-year-old girl--active in high school sports and very social with a large group of friends. She became sexually active when she was 15, and, like many of her friends, occasionally smoked at parties or after school. After she missed two periods in a row, Valerie thought she should call a health care provider. When she learned she was pregnant, she was forced to face another challenge: could she quit smoking? |
