I've been hearing a lot about the e-cigarette lately. What's the deal with these things?

The e-cigarette is a device that vaporizes a liquid solution called e-juice, which typically contains nicotine and flavorings. It looks like a cigarette, but instead of burning tobacco it heats up a small amount of e-liquid and turns it into a vapor that is inhaled by the user. This allows people to get their nicotine fix without inhaling all the harmful chemicals found in traditional cigarettes.
