Smoking and pregnancy

Smoking and pregnancy

If you stop smoking while pregnant, it will help give your baby the best start in life and will make you healthier.

Stopping smoking is a great way to improve your chances of conceiving and giving birth to a healthy baby.

It’s never too late to stop smoking as the health benefits of quitting begin as early as 20 minutes after your last smoke.

It’s not just mothers-to-be, but their partners who should quit smoking. Passive smoking can also harm mother and baby, so a smoke-free household means a healthier family. It can be challenging, but with some support you can reach your goals.

Smoking and fertility

For both women and men, quitting smoking increases your fertility.

Women who smoke can have:

• difficulty in conceiving
• early onset of menopause
• cervical and vulvar cancer.

Men who smoke may have:

• trouble getting and maintaining an erection
• lower sperm count
• damage to DNA in sperm causing health problems in your baby.

How smoking affects your baby

Smoking during pregnancy exposes your baby to harmful chemicals. Every time you smoke, the baby effectively smokes too, as harmful nicotine and other chemicals pass through the placenta and into the fetus. Smoking also reduces blood flow for your baby.

Smoking while pregnant can result in a far higher risk of:

• miscarriage, stillbirth or ectopic pregnancy
• premature birth
• low birth weight
• damage to your baby’s heart and lungs.

After your baby is born, there are still health and developmental risks if you or other household members smoke. These include:

• around three times higher risk of Sudden Infant Death Syndrome (SIDS)
• respiratory disorders such as asthma
• increased risk of obesity
• increased risk of childhood cancers, high blood pressure and allergies
• middle ear disease.

Smoking and breastfeeding

When you smoke, nicotine and other harmful chemicals are passed on to your baby through breast milk. Even if you continue smoking, breastfeeding is still best for your baby.

Passive smoking

Other people’s smoke can harm both mother and baby. If it’s not possible for all family members to quit, at least commit to a smoke-free household. People who smoke should do so outside.

In most states and territories, it’s illegal to smoke in a vehicle while a child is present. There are also smoking bans in public spaces.

Support to give up smoking

Totally quitting smoking is the best goal, but you might find it easier to cut down on your smoking to begin with.

There are many different quitting methods and you might need to try a few. Every attempt to give up cigarettes is a step towards becoming an ex-smoker. Talking to a health practitioner is a good starting point, as is contacting Quitline.

Methods that work include:

• going cold turkey - simply stopping works for many people
• using Quitline resources
• mobile apps, such as Quit for you - Quit for two
• support from family and friends
• prescription medication
• nicotine replacement therapies.

Prescription medications can help by reducing withdrawal symptoms such as cravings, anxiety and irritability.

Nicotine replacement therapies (NRT) can help. They are readily available from pharmacies and some supermarkets, and come in two categories:

• steady response products, such as nicotine patches
• quick response products, such as chewing gum, lozenges, tablets and inhalers.

Before using any NRT or prescription medication it is important for you to inform the chemist or your doctor that you are pregnant or breastfeeding and follow their advice.

While some smokers have found vaping or e-cigarettes to be useful aids in giving up tobacco and tar, the long-term health effects are still unknown. Due to their ingredients, even non-nicotine e-cigarettes may be harmful to your baby. Vaping or using e-cigarettes are not recommended.

It might take you a few goes to quit. It does for most people. But it’s worth it to keep trying.
