When describing this study to the pregnant women, we will explain that half of the couples will be randomly assigned to receive face-to-face counseling plus a self-help cessation guide (Guia) while the other half will receive the self-help smoking cessation guide only. When a woman agrees to have us meet with her and her husband/partner, we will send her home with two consent forms, one for her and one for her husband/partner, along with a small gift for the upcoming baby. We also will set up a time and place to meet the couple for their initial data assessment. We will not collect information about legal status of patients.
