Quitting smoking is a common New Year's resolution but it's easier said than done.

The American Lung Association says 6 out of 10 smokers require multiple attempts to stop smoking. Some of them are turning to battery powered cigarettes, or e-cigarettes, to kick the habit.

But there's an alarming trend: teen cigarette smoking is down, but a recent study indicates e-cigarette use among teens may be on the rise.

These battery powered cigarettes come in a variety of flavors like cherry crush, mango, and vanilla, but smokers are still inhaling nicotine. It's just in vapor form instead of smoke.

What's the appeal? And why are so many teens doing it?
