CHANTIX contains no nicotine. You may wonder how a non-nicotine pill could help you quit smoking. Well, first you have to know how nicotine works.

There are receptors for nicotine in your brain. When you smoke, the nicotine you inhale attaches to these receptors. This sends a message to a different part of your brain to release a chemical called dopamine. Dopamine gives you a feeling of pleasure. But it does not last long. That's why your body craves more nicotine. This can become a vicious cycle.

CHANTIX is different from most other quit-smoking products. It targets nicotine receptors in the brain, attaches to them, and blocks nicotine from reaching them. By activating these nicotine receptors, it is also believed that CHANTIX causes less dopamine – compared to nicotine – to be released.
