The Food and Drug Administration has approved another pill to help smokers quit.
Several studies in Europe have shown the Pfizer drug helps more than one-in-five smokers quit after a year of use.
It's just the second nicotine-free anti-smoking drug to get F-D-A approval. The company says the twice-daily pill will be marketed as Chantix.
A smoking expert at the University of California, San Francisco calls the drug "a welcome new addition." The professor says the more treatments available, "the better."
The drug works by cutting the pleasure of smoking and reducing withdrawal symptoms.
