electronic cigarettes, also referred to as Smokeless cigarettes or e-cigarettes, are electronic devices that look and act like traditional cigarettes, yet without using tobacco. Smokeless cigarettes produce no harmful smoke. Just as traditional cigarettes, smokeless cigarettes provide doses of nicotine to the body. However, the method used in the two types of tobacco differs by a great degree.

electronic cigarettes use liquid nicotine which is stored in a mouth piece and delivered in form of vapor that is produced by heating the liquid using an atomizer. As a result, you are not subjected to tar or odd harmful chemicals which are likely to bring harm to you when you smoke tobacco. More importantly, no smoke also means the ill-effects of passive smoking are kept at bay.

The smoke in traditional cigarettes kills you instead of the nicotine in it. This is what you are likely to come across in most of the electronic cigarettes advertisements. However, this is just a misconception. Nicotine is as harmful for human health as the various chemicals in tobacco smoke are.

Although electronic cigarettes are good in many aspects, they do have some drawbacks. While an individual turns to electronic cigarettes thinking that these products are harmless, he will eventually be addicted to nicotine to an extent where withdrawal is impossible. Nicotine addiction is a severe problem which is likely to cause irreversible damage to the brain in the long run. Because of their nicotine contents, e-cigarettes are also considered to be harmful for individuals who are sensitive or allergic to nicotine.

Although the manufacturers argue that electronic cigarettes are without harmful chemicals, which is different from traditional tobacco smoke, the fact is that chemicals like Propylene Glycol used in electronic cigarettes haven't been proved without bad chemicals on human health. The acute toxicity of Propylene Glycol is no doubt low as the electronic cigarettes reviews reveal, but in the long run, even such low toxicity will develop into major health issues. Even if side effects of electronic cigarettes exist, lack of testing of them has kept most of the people without knowledge of their alleged side-effects.
