I've been hearing a lot about the dangers of e-cigarettes. What are they and is it true that they are harmful to my health?

E-cigarettes are devices that use an electronic heating element to vaporize a liquid solution, commonly called e-liquid or e-juice. They typically contain nicotine, flavorings, and other additives. The main difference between traditional cigarettes and e-cigarettes is that e-cigarettes do not produce smoke, but instead generate a vapor that contains nicotine and other chemicals.
