Chantix is different

While smoking, the nicotine from your cigarette drives receptors in your brain to bring out a chemic known as dopamine, which is what makes many of the positive impressions you get when you smoke. When you quit smoking, going without dopamine causes the some of the times miserable signs and symptoms of drug withdrawal. Signs and symptoms such as irritability, insomnia and difficulty focusing begin four to six hours after your last cigarette and can endure a month after you quit smoking.

Nicotine substitution products, including the patch, gum and lozenges, and the antidepressant bupropion (Zyban), can help you stop smoking, in part, by staying on to eject low levels of dopamine in your brain. In this way, these stop smoking medications lessen your craving for nicotine and reduce the signs and symptoms of withdrawal.
Chantix works in this way as Stop Smoking Aids, too. Chantix causes the release of low levels of dopamine in your brain to help reduce the signs and symptoms of withdrawal. Additionally, Chantix stops nicotine receptors in your brain. So if you lapse and have a cigarette, your cigarette doesn't provoke your brain's receptors the way it did in the past. Cigarettes turn much less enjoyable, and your want to get back to regular smoking again possibly reduced.
