Erin Barringer, a nursing assistant in the Neurosciences Hospital, began smoking socially in 10th grade, and over the years she increased her smoking to one-half pack of cigarettes a day. She continued at this level until 2010 when she found out she was pregnant. She remained tobacco free through her pregnancy and breastfeeding until her daughter, Jalliyah, was about 6 months old. At that time, she returned to smoking socially — and also did so to help deal with stress.
