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?

Kaci Hickox is speaking out after a judge in Maine rejects the state's call for a mandatory home quarantine for the nurse who recently returned from treating Ebola patients in Sierra Leone.
Hickox is now free to go to stores, restaurants, movie theaters, wherever she chooses. But she isn't totally in the clear.
Alexandra Field has the latest.
Negotiations between the state of Maine and nurse Kaci Hickox over the limits of her quarantine ended today with no resolution. The disagreement was over the guidelines on how and when she could leave her house, while staying away from public places.
Early Thursday morning, Hickox and her boyfriend left their Fort Kent home for a bicycle ride around town, followed by state police.
Police were not authorized to arrest her, the governor saying they were there for her protection and to monitor any interactions with the public.
But Gov. Paul LePage said he would use "the full extent of his authority" to protect public safety.
James Majka lives down the street from Hickox in Fort Kent, Maine, a small town with a population just above 4,000. In an interview with CNN's Erin Burnett, Majka says Hickox should have remained in quarantine.
Kaci Hickox, the nurse forcibly quarantined in New Jersey after returning from treating Ebola patients in West Africa is back in Maine where now she refuses to quarantine herself at home.
Maine officials want Hickox to stay at home until she passes the 21-day mark from the last time she was in contact with Ebola patients.
Hickox says she has twice tested negative for Ebola and feels it's reasonable for her to self-monitor but there's no need to stay home in quarantine.
"I don't plan on sticking to the guidelines," Hickox said on the "Today Show." "I remain appalled by these home quarantine policies that have been forced on me."
Hickox is going even further by hiring a high-profile attorney who has told officials they have till Thursday to change their position. If they try to force his client to comply, he says they'll take them to court.
