Chantix. Isn't that Romanian for a cabaret singer?

Chantix is just one of the many prescription medications that helps smokers quit. Their commercials are very well done and the real people actually seem real. But as a person who spent years trying to quit and eventually did, I cannot imagine why anyone would risk taking this product. First of all the statistics aren't that great: 44% of users quit in weeks 9-12 as opposed to 18% on a sugar pill. That's a pretty good percentage for a placeo. But Chantix is far from a sugar pill. This commercial spends nearly an entire minute on the dangers and side effects of Chantix. So, I suspect that continuing to smoke doesn't pose significantly more risk than taking Chantix. Does anybody have a light?
