Peter Chugaev has been smoking for 45 years and for the past 15 he's been trying to quit.
Now he's turning to electronic cigarettes to try to quit. Users inhale, but there's no smoke. Taking a puff triggers a heating coil, which warms up liquid nicotine, in a plastic filter resulting in nicotine-filled vapor.
But hard core smokers aren't the only ones seeking out e-cigarettes.
Young people are as well and this has some health experts concerned because these products are not federally regulated and there is limited research on their safety.
These products come in flavors that may appeal to young people.
Health experts worry that once addicted to the nicotine in e-cigarettes, young people may branch out and try tobacco products.
Manufacturers say they don't market to kids and maintain that electronic cigarettes are a good alternative to conventional cigarettes.
And for Peter, e-cigarettes seem to be helping. He is down from a pack a day of regular cigarettes to about half that and hopes to kick the habit by the end of the year.
