In Switzerland, tobacco smoking is a major public health problem, especially among pregnant women. Health problems encountered by pregnant women and their fetuses require specific care to assist smoking cessation. A specific consultation to support smoking cessation during pregnancy was created in May 2019 at the maternity ward of the University Hospitals of Geneva, with the support of the Fondation Privée des Hôpitaux Universitaires de Genève and Carrefour addictionS/CIPRET-Genève. The creation of a network of health professionnals trained in smoking cessation is an important step to support women during their cessation process.
