Can You Vape When Pregnant?

August 08, 2025 — By Daire John Patten

Pregnancy is an exciting time filled with many changes. However, it’s also a period when you need to be particularly careful about your health choices. One of the most common questions pregnant women ask is whether it's safe to vape during pregnancy. 

While some might assume vaping during pregnancy is a better alternative to smoking, it's important to consider the risks associated with vaping in pregnancy. Let’s take a closer look at the effects of vaping and pregnancy, and whether electronic cigarettes are a safe option.

 

What is Vaping During Pregnancy?

Vaping during pregnancy involves using an e-cigarette (electronic cigarette) to inhale vaporised liquid, often containing nicotine and other chemicals. While many women turn to e-cigarettes and pregnancy as a way to reduce the harm caused by smoking, there are significant risks involved. Even though vaping while pregnant might seem less harmful than smoking traditional cigarettes, the effects on the developing baby can still be dangerous.

Can Vaping Cause Miscarriage?

One of the most alarming concerns for expectant mothers is whether vaping can cause miscarriage. The answer is yes, vaping while pregnant can increase the risk of miscarriage. According to recent studies, nicotine in e-cigarettes can reduce blood flow to the baby, depriving them of oxygen and nutrients, which increases the likelihood of pregnancy complications. In fact, studies show that women who vape during pregnancy are at a higher risk of miscarriage compared to non-smokers or women who don’t use e-cigarettes.

Vaping While Pregnant: The Risks

When considering whether vaping while pregnant is safe, it’s important to know the potential risks involved. Here are some of the risks of vaping during pregnancy:

  • Nicotine Exposure – Nicotine, found in many e-cigarettes, can restrict blood flow to the baby, reducing oxygen and nutrients needed for proper growth and development.
  • Preterm Birth – Women who vape while pregnant are at a higher risk of giving birth prematurely.
  • Low Birth Weight – Babies born to mothers who vape during pregnancy are more likely to have low birth weight.
  • Brain Development Issues – Nicotine can impair brain development, affecting cognitive function and increasing the likelihood of learning disabilities later in life.

Is It Safe to Vape While Pregnant?

Many women wonder, "Is vaping bad for pregnancy?" The short answer is yes. Vaping while pregnant can expose your baby to harmful chemicals, including nicotine, which can restrict blood flow and interfere with development.

This is why vaping in pregnancy is not considered safe. Even though e-cigarettes and pregnancy may seem less dangerous than smoking, both still involve exposure to harmful substances that can affect the baby.

Vaping During Pregnancy 1st Trimester

The 1st trimester is one of the most critical stages of pregnancy when the baby’s organs are forming. Vaping while pregnant 1st trimester is especially dangerous because nicotine exposure can disrupt this process, leading to birth defects or other complications.

This is when the baby's nervous system, heart, and lungs are developing, making them more vulnerable to damage caused by substances in e-cigarettes.

Can You Smoke When Pregnant?

Just like vaping while pregnant, smoking traditional cigarettes during pregnancy is extremely harmful. The dangers of smoking while pregnant are well documented, and smoking and pregnancy risks include low birth weight, preterm birth, and developmental delays.

Smoking cigarettes while pregnant exposes your baby to harmful toxins that can interfere with normal development. Whether it’s e-cigarettes and pregnancy or traditional smoking, both present significant risks to your baby's health.

Does Vaping Affect Pregnancy?

One of the most common concerns for expecting mothers is whether vaping affects pregnancy. The short answer is yes, it does. Nicotine exposure from e-cigarettes can harm fetal development, including disrupting brain development, which can affect learning and memory.

Furthermore, vaping while pregnant can reduce the oxygen supply to the baby, potentially leading to developmental delays and complications.

Vaping Around Babies

If you think vaping around babies is safer than vaping during pregnancy, think again. Secondhand exposure to e-cigarette vapour can still be harmful to babies, even after birth.

Vaping while pregnant can result in long-term health issues for your child, and secondhand exposure is also dangerous. It’s best to quit vaping while pregnant entirely and avoid exposing your child to harmful chemicals.

Can You Vape While Pregnant?

So, can you vape while pregnant? The answer is clear: no. Vaping during pregnancy, including using e-cigarettes, is not safe for you or your baby.

Vaping during pregnancy introduces nicotine and harmful chemicals into your bloodstream, which can restrict blood flow to your baby and interfere with fetal development.

Mothers Who Vaped During Pregnancy

Some women may wonder, “Mothers who vaped during pregnancy, did they experience complications?” While some women may have delivered healthy babies, the risks associated with vaping while pregnant are real, and the long-term effects are still being studied. It’s important to remember that even if some mothers who vaped during pregnancy didn’t experience immediate complications, the risks to the baby’s health still exist.

Conclusion: The Bottom Line

Vaping when pregnant is dangerous and can lead to serious complications, including miscarriage, preterm birth, brain development issues, and more. The risks of vaping while pregnant far outweigh any perceived benefits. It’s essential to talk to your doctor and find support to quit if you're currently vaping while pregnant.

  • A study published in Paediatrics found that women who vape during pregnancy are more likely to have babies with low birth weight and preterm birth.
  • According to the American College of Obstetricians and Gynaecologists (ACOG), the use of e-cigarettes and pregnancy has been shown to increase the risk of birth defects and other developmental issues for babies exposed to nicotine.

If you’re asking, “Can I vape when pregnant?” The best answer is no. Protect your baby by quitting vaping while pregnant today.
