*Enceinte et toxicomanie* examines the complex medical, psychological, and social issues surrounding substance dependence during pregnancy. Written by Françoise Molenat, the book addresses how addiction can affect prenatal care, maternal well-being, fetal development, and the relationship between patient and caregiver. It is intended for professionals working in maternity, addiction treatment, social support, and public health, offering a focused perspective on prevention and intervention in perinatal settings. Rather than treating pregnancy and addiction as separate concerns, the work considers how they intersect in clinical practice and everyday care. It highlights the need for attentive support, coordinated services, and nonjudgmental approaches for pregnant patients facing dependency. The book serves as a concise resource for understanding risk, prevention, and care strategies in this sensitive area.
