Vapes are electronic devices that let you inhale nicotine in a 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.

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.

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

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.
