Smokeless cigarettes or electronic cigarettes have become very popular among people who are trying to cut down on their smoking. As their name implies, smokeless cigarettes provide all the flavor and nicotine as a traditional cigarette without the harmful smoke, tar and carcinogens that go with it. Although doctors warn that they are not 100 percent safe, they are certainly safer than traditional cigarettes, and they can be enjoyed even in places where smoking isn't allowed.
Smokeless cigarettes are electronic devices that resemble traditional cigarettes, but they are really more like an atomizer. They work by vaporizing a solution that usually contains small amounts of nicotine. The solution is usually flavored to taste like tobacco, although there are other flavors available. The solution is vaporized and inhaled, and what is exhaled as "second hand smoke" is really no more than water vapor. This makes smokeless cigarettes popular in places where smoking is not an option.

Although they are unlikely to completely replace smoking altogether, many people are excited about the prospect of being able to get their nicotine fix without having to light up and destroy their lungs.
