Can You Vape When Pregnant
Vape When
Pregnant
NHS guidance is clear: quitting nicotine entirely is best. NRT is preferred over vape for pregnant smokers. Vape only preferred over continued smoking. Here is the full guidance plus how to access NHS support.
NHS guidance on nicotine during pregnancy is clear with a four-step priority order. (1) Quitting nicotine entirely is best for you and your baby. (2) Nicotine replacement therapy (patches, gum, lozenges) is the preferred second option for pregnant smokers who cannot quit cold. (3) Vaping is preferred only over continued smoking when neither quitting nor NRT is working. (4) Continued smoking is the worst option. If you were not using nicotine before pregnancy, do not start vaping. Speak to your midwife, GP or NHS Stop Smoking Services for personalised support. This is general consumer information, not medical advice.
The NHS priority
and how to access support
Three facts that summarise the NHS position, the preferred alternative and the first step for any pregnant woman seeking support.
NHS guidance
Quitting nicotine entirely is the NHS recommended option during pregnancy. Second best is NRT. Vape is only preferred over continued smoking.
Over vaping
For pregnant smokers who cannot quit cold, patches and gum are preferred over vape under NHS guidance.
For personal advice
Your midwife, GP or NHS Stop Smoking Services provide personalised support. General online information does not replace personal care.
Quit first. NRT second. Vape only over smoking. Never start during pregnancy.
The NHS position on vaping during pregnancy is clear: quitting nicotine entirely is the best option for the developing baby and for you. If quitting completely is not possible for a pregnant smoker, nicotine replacement therapy (patches, gum, lozenges) is preferred over vape. Vape is considered preferable only to continued smoking when neither quitting nor NRT is working. If you were not using nicotine before pregnancy, do not start vaping. Here is the full picture plus how to access pregnancy-specific NHS support. This article is general consumer information, not medical advice.
The NHS priority order
For pregnant women currently using nicotine, NHS plus OHID guidance establishes a clear priority order:
1. Quitting nicotine entirely. The best option for the baby and for you. NHS Stop Smoking Services offer pregnancy-specific support that has the highest success rates for quit attempts during this window. Behavioural support plus medication where appropriate.
2. Nicotine replacement therapy (NRT). If quitting cold is not working, NRT (patches, gum, lozenges) is preferred over vape during pregnancy. NRT delivers controlled nicotine without the additional components of vape or smoke. Your GP can prescribe NRT during pregnancy.
3. Vaping. Preferred only over continued smoking. If you are a smoker who cannot quit plus cannot use NRT, switching to vape removes combustion by-products that are the main driver of smoking-related pregnancy harm. The nicotine-specific effects remain.
4. Continued smoking. The worst option for the baby. NHS guidance is clear that any of the above three options are better.
If you were not using nicotine before pregnancy, starting vape during pregnancy is not recommended. The potential small nicotine exposure provides no benefit for someone not already addressing an existing habit.
Why nicotine affects pregnancy
Nicotine crosses the placenta freely and reaches the developing fetus. Research has identified several specific effects:
- Cardiovascular development. Nicotine is a vasoconstrictor that affects blood flow to the placenta plus the developing baby. Chronic reduced blood flow can affect fetal growth plus development.
- Brain development. Nicotine binds to receptors in the developing brain. Research on animal models plus observational studies in humans suggest effects on neural development.
- Birth weight. Maternal nicotine use is associated with lower birth weight. Lower birth weight is itself associated with several infant health outcomes.
- Preterm birth risk. Nicotine use has been associated with increased risk of preterm birth in some research.
- SIDS and respiratory outcomes. Some research links prenatal nicotine exposure to increased SIDS risk plus respiratory issues in childhood.
Most of this research is from smoker studies. The nicotine-specific mechanisms are the same for vape but combustion by-products that cause additional smoking-specific harms are absent.
NHS pregnancy-specific stop smoking support
UK pregnant women have access to specialised NHS Stop Smoking support that is specifically designed for pregnancy:
- Specialised pregnancy advisors. Trained to support pregnant women plus new mothers through cessation.
- Carbon monoxide testing. Breath testing during antenatal appointments that identifies recent smoking.
- Incentive programmes. Some areas offer financial incentives for pregnant women who successfully quit smoking.
- Partner support. Programmes often include support for partners who also smoke.
- Free NRT. Available on prescription during pregnancy where appropriate.
- Ongoing support. Continued support after birth to prevent relapse.
Access this support through your midwife at antenatal appointments, your GP or directly through NHS Better Health online.
Breastfeeding considerations
Nicotine passes into breast milk. The general principles for breastfeeding are similar to pregnancy:
- Quitting nicotine entirely is best.
- NRT during breastfeeding is generally preferred over vape.
- Vape is preferred over smoking.
- Timing nicotine use immediately after breastfeeding rather than before reduces peak nicotine exposure to the baby.
Speak to your midwife, health visitor or GP about specific guidance for your situation. NHS Stop Smoking Services continue to support new mothers.
If you are already vaping when you discover you are pregnant
Many women find out they are pregnant while already using vape. Do not panic and do not stop abruptly without support if you have been using high-strength vape. Here is what to do:
- Book an early midwife appointment. Be honest about your vape use including strength plus frequency.
- Consider a quit plan. NHS Stop Smoking Services can support you through the process. Structured quitting is more likely to succeed than going cold turkey alone.
- If cold turkey feels impossible, discuss NRT alternatives with your GP. Patches in particular deliver steady nicotine with reduced total exposure.
- Reduce gradually if appropriate. Step-down nicotine strength plus reduce frequency under medical guidance.
- Avoid guilt-driven decisions. The key is moving toward less nicotine exposure not achieving perfection instantly.
