If quitting smoking is your New Year's resolution, consider trying Chantix. It's the first smoking cessation drug that's designed to address the withdrawal symptoms that make kicking the habit so hard. Chantix works by mimicking nicotine, so smokers weaning themselves off cigarettes will still feel the satisfying effects of nicotine without its addictive qualities and damaging effects on the lungs and other organs. The 12-week program of pills alone may not be enough to quit, however; smokers who took Chantix while also participating in counseling were able to remain smoke-free longer than those who just popped the pills.
