Using e-cigarettes before, during and after pregnancy

E-cigarettes are significantly less harmful to health than tobacco. This page provides resources and information about the use of e-cigarettes before, during and after pregnancy.

Smoking or exposure to secondhand smoke during pregnancy is responsible for an increased rate of stillbirths, complications during labour, premature birth, miscarriages, birth defects and Sudden Infant Death Syndrome (SIDS). Based on the latest evidence, e-cigarettes are significantly less harmful than cigarettes and are an effective aid for quitting. However, it is important to use UK e-liquids which have been regulated by the MHRA and never home-made or illicit vaping substances.

Many women who smoke during pregnancy are using e-cigarettes as an aid to quit or cut down and members of the midwifery team may be asked for advice.


These resources have been designed by the Smoking in Pregnancy Challenge Group to inform health professionals and support conversations with pregnant women who smoke and are inquiring about e-cigarettes. The resources will be updated in line with any updates to NICE guidance, significant evidence updates or in the event that a medically licensed e-cigarette comes to market. The ‘Infographic for pregnant women‘ was developed in collaboration with Tommy’s

Disclaimer: None of the Challenge Group’s resources have input from organisations with vested interests in the vaping or tobacco industries

Physical copies of these resources can be ordered by midwifery teams via this order form.

Please note: These resources should be ordered by maternity units to be used consistently across the service. If we get very small requests we may need to follow this up with your service manager.
