Tobacco and pregnancy: protecting baby

IRIS Prévention
3 February 2027
Quitting smoking during pregnancy is one of the greatest gifts you can give your baby, and it's never too late to do it.

Pregnancy is a special time when quitting smoking takes on a strong meaning: it is about protecting the baby. Smoking during pregnancy poses risks, but quitting at any stage brings immediate benefits. Far from feeling guilty, the important thing is to know that caring support exists.

1. The risks of smoking during pregnancy

Smoking during pregnancy exposes the baby to various risks, as tobacco substances pass the placental barrier and reduce oxygen supply. This can impact the development of the fetus and the course of the pregnancy.

2. The benefits of stopping, at any time

The good news is clear: quitting smoking, at any time during pregnancy, reduces the risks and benefits the baby. The earlier you stop, the better, but stopping even during pregnancy brings benefits. It's never too late.

3. Adapted support

Quitting during pregnancy may seem difficult, but specific support exists. Health professionals who monitor the pregnancy (midwife, doctor) can help, including with nicotine substitutes when indicated, under supervision. The stop is prepared and sustained.

    • Talk to the midwife or doctor following the pregnancy
    • Benefit from specific support
    • Consider appropriate aid under medical supervision

4. Kindness rather than guilt

Blame is counterproductive. The important thing is to act: every cigarette avoided counts, and stopping, even partially at first, is progress. The co-parent who stops also supports the process and protects against passive smoking.

This sensitive subject deserves caring support: health professionals are there to help, without judging.
