Chantix is a pill that does not contain any nicotine. Chantix works by bonding itself to the nicotine receptors in the brain so that nicotine can not. This serves two purposes. Like nicotine replacement therapies, Chantix triggers the release of a small amount of dopamine to help calm nicotine cravings. But if you slip and smoke a cigarette, Chantix blocks the nicotine in the cigarette from being able to attach to the nicotine receptors in your brain.

Typical Chantix side effects include:
nausea
vomiting
constipation
disruptions in dream pattern

Also you can use zyban too to quit smoking. Check Emedoutlet.com to know more about these medications and side effects
