There is little research on the safety of vaping in pregnancy, but it’s likely to be substantially less harmful for you and your baby than smoking.
The NHS recommends the use of nicotine replacement therapy products such as patches and gum for those who need support to quit smoking while pregnant.
It says: “If you find vaping helpful to quit and to stay smoke-free, it is much safer for you and your baby than continuing to smoke.
“The most important thing is to not smoke when pregnant or around pregnant women.”
