If you're fed up of smoking and want to kick the habit then the revolutionary e-cigarette could be just the thing you've been waiting for. It is being hailed as the safer smoking alternative and has the look and feel of smoking a real cigarette, yet in reality it emits an odourless and harmless smoke-like vapour while providing you with the nicotine dose you crave.

If you want to buy an electronic cigarette you may want to learn a little about the device first. The e-cigarette is a battery powered device that provides nicotine to the user in a vaporized state once inhaled, without the use of tobacco or actual tobacco smoke. These devices are non-flammable and don't run the risk of passive smoking which is one of the reasons they are being hailed as a safer smoking alternative.

Electronic cigarettes work by using advanced microelectronic technology and if you buy an e-cigarette you could be pleased to know that they are re-usable though disposable electronic cigarettes have been developed if you prefer. All of the components of the device are replaceable or refillable so you won't have to worry about making it last if you buy an electronic cigarette.

The device works when a user inhales on the e-cigarette. This causes the liquid nicotine inside the nicotine chamber to be drawn into the atomisation chamber. Once inside the atomisation chamber, the battery will heat up the liquid nicotine and this leads to the user inhaling nicotine vapour.

E-cigarettes are becoming increasingly popular as research has found it is tobacco as opposed to nicotine that has been associated with smoking related illnesses. Despite their popularity however, e-cigarettes are still not completely legal in some countries.

It is not recommended that any person under the age of 18, or non-smokers use electronic cigarettes. These devices are currently unrestricted in the United Kingdom and the United States of America, though they are strictly prohibited in Brazil, Panama, Canada and Singapore. While in New Zealand, you can only buy the electronic cigarette as a registered medicine, in Australia and Denmark you may use the electronic cigarette but only without the use of nicotine.

If you are still undecided about whether or not to buy an electronic cigarette there are some useful internet websites that will be able to provide you with more information.
