This story vastly overstates the potential of Chantix to help smokers quit. In the three comparable and support intense Chantix studies only 1 in 5 users succeeded in quitting for one-year. Real-world use will likely see Chantix's performance fall to less than 1 in 10. I've written a critical review of Pfizer's Chantix (varenicline) studies at the following link:

Smokers want an effective intervention and I wish I could state otherwise but Chantix isn't it.

I used Chantix and had great success. It definitely blocks those nicotine receptors in the brain.I think we'll be hearing alot about this drug in the near future.It really helped me quit!!!
