Over recent years, e-cigarettes have become a very popular stop smoking aid in the UK. Evidence is still developing on how effective they are, but many people have found them helpful for quitting.
An electronic cigarette (e-cigarette) is a device that allows you to inhale nicotine without most of the harmful effects of smoking.
E-cigarettes work by heating and creating a vapour from a solution that typically contains nicotine; a thick, colourless liquid called propylene glycol and/or glycerine; and flavourings. As there is no burning involved, there is no smoke.
Research shows that e-cigarettes can help you give up smoking.
If you want to use an e-cigarette to help you quit, you’ll give yourself the best chance if you get expert support from your local stop smoking service. In the year up to April 2015, two out of three people who used e-cigarettes in combination with the NHS stop smoking service quit smoking successfully.
Different things work for different people and, particularly if you’ve already tried other methods of quitting smoking without success, you might want to give e-cigarettes a go.

E-cigarettes do not produce tar and carbon monoxide – two of the main toxins in conventional cigarette smoke. The vapour from e-cigarettes has been found to contain some potentially harmful chemicals also found in cigarette smoke, but at much lower levels.
E-cigarettes are still fairly new and we won’t have a full picture on their safety until they have been in use for many years. However, according to current evidence on e-cigarettes, they carry a fraction of the risk of cigarettes.
New rules for e-cigarettes and their refill containers came into effect in the UK on May 20 2016. These rules ensure that there are minimum standards for the safety and quality of all e-cigarettes and refill containers.
There are two types of safety concerns associated with e-cigarettes:
It's important that any e-cigarette safety concerns are reported and monitored, which you can do through the Yellow Card Scheme.
