The US Food and Drug Administration (FDA) has launched a new campaign to encourage cigarette smokers to quit. The campaign's primary message is this: Every try counts.

Smoking can shave years off a person’s life and lead to an early death. Even if a man lives into his 70s, smoking can still steal several years of life.

It looks like a cigarette, feels like a cigarette, but doesn't have the tobacco content or familiar smell of regular cigarettes. Rather, these electronic cigarettes come in a variety of flavors that emit water vapor as they simulate the effect of smoking.
