Vapes are electronic devices that let you inhale nicotine in an aerosol, or vapour, instead of smoke. This is done by heating a solution (e-liquid) that typically contains propylene glycol, vegetable glycerine, flavourings and nicotine.

E-liquids come in different nicotine strengths, so you control how much nicotine you need to help with cravings and other withdrawal symptoms, such as feeling irritable and having low mood.

Nicotine itself is not very harmful and has been used safely for many years in medicines to help people stop smoking.

Help break the routines of smoking cigarettes

The routines and rituals of smoking can be hard to stop, so vaping can help you gradually let go of these while immediately reducing the health risks of smoking cigarettes.

Some people find vaping helps them because the hand-to-mouth action is like smoking, plus you get similar sensations, like throat hit (the “kick” in the back of your throat when you inhale).

Any smoking is harmful and you will only get the full benefits of vaping if you stop smoking completely. Some people manage to make a full switch very quickly, while for others it can take a bit longer.

You’re roughly twice as likely to quit smoking if you use a nicotine vape compared with other nicotine replacement products, like patches or gum.

Is vaping harmful?

Evidence shows that vaping is substantially less harmful than smoking. Vaping exposes users to far fewer toxins and at lower levels than smoking cigarettes.

Switching to vaping significantly reduces your exposure to toxins that can cause cancer, lung disease, and diseases of the heart and circulation like heart attack and stroke. These diseases are not caused by nicotine, which is relatively harmless to health.

However, vaping is not risk-free. Non-smokers and young people under 18 should not take up vaping.
