I've been hearing a lot about e-cigarettes. What are they and should I try using one?

E-cigarettes are devices that use an atomizer to vaporize nicotine, usually in combination with flavorings or other additives. They typically look like cigarettes, but instead of burning tobacco, the user inhales aerosolized nicotine and flavoring. The main benefit is that it’s much less harmful than smoking traditional cigarettes, since there is no combustion involved.
