Smoking, as we all know, is a bad habit that can lead to chronic illnesses, such as cancer, heart disease, lung disease, ulcers and so on. The solution for preventing such health complications is to quit smoking altogether, but this is easier said than done because smoking is such an addictive habit that's quite difficult to kick off.

Why? When you stop smoking, you are bound to get cravings and are very likely to reach out for a cigarette again. Now there is an alternative to the traditional cigarette – the e-cigarette or ecigs. An e-cigarette is an electronic device that gives off a vaporized nicotine flavor, which makes a person feel like they are really smoking a cigarette. The nicotine solution is filled into refillable cartridges and upon activation it is vaporized by an electronic heating unit inside the cigarette. In a manual e-cigarette, this heating unit is activated through the press of a button, but in an automatic one, it is activated by simple inhaling.
