E-cigs and vapes

E-cigarettes are fairly new and there are still some things we do not know. However, current evidence on e-cigarettes indicates they are much less harmful than smoking.

Cigarettes deliver nicotine along with thousands of harmful chemicals. E-cigarettes allow you to inhale nicotine through a vapour rather than smoke. By itself, nicotine is relatively harmless.

E-cigarettes do not produce tar or carbon monoxide, the two main toxins in cigarette smoke. Carbon monoxide is particularly harmful to developing babies. The vapour from an e-cigarette does contain some of the potentially harmful chemicals found in cigarette smoke, but at much lower levels.

If using an e-cigarette helps you to stop smoking, it is much safer for you and your baby than continuing to smoke.

Little research has been conducted into the safety of e-cigarettes and e-liquids in pregnancy. It is not known whether the vapour is harmful to a baby in pregnancy.

If you're pregnant, licensed NRT products such as patches and gum are the recommended option to help you stop smoking.

But if you find using an e-cigarette helpful for quitting and staying smoke-free, it's much safer for you and your baby than continuing to smoke.

Unlike nicotine replacement therapy (NRT), such as patches or gum, e-cigarettes are not available on an NHS prescription. If you want to use an e-cigarette, you can still get free expert help from a stop smoking adviser.
