A new Pfizer drug that has shown to help more than one in five smokers quit the habit received federal approval recently.

Chantix comes in pill form and may help those who wish to give up smoking in two ways: it provides some nicotine effects to ease the withdrawal symptoms as it also helps block the satisfaction effects of nicotine.

Cardiologist David Bailey says "So it is good to stop smoking and it seems to have some effect on trying to keep them away the cigarettes down the road."

Pill or no pill, as any smoker like Marvelle Colby will tell you, quitting is not easy. And even if those who are successful, like Marvelle, can tell you that they can remember those struggles as if it were yesterday. "I had tried counting cigarettes, you know, you only allow yourself 10 a day, then 9 a day, I had tried that. I tried the patch. So the patch didn't work, I had acupuncture. I did everything."

Dr. Bailey also says that it's important to keep trying - because quitting can help save your life. "When you look at people who smoke, you're going to probably die on average about 13 or 14 years earlier if you are a smoker, if you are a man or a woman. So it's a really complete nightmare."

Chantix received priority review for approval by the FDA because of its potential to be a significant therapeutic advance over existing therapies to help you quit smoking.

According to the American Cancer Society 70% of smokers want to quit but only 5% succeed. Perhaps this drug can help make a difference.
