Nicotine replacement therapies got lot of attention for many years but then Zyban came in and it was touted as the best thing for smokers as it did not contain nicotine. However, people who took Zyban had seizures and hence it never reached the zenith of popularity. Champix on the other hand, being the latest drug for smoking cessation, achieved remarkable success in a very short time.

Ever since Champix has come in the market, there has been no looking back and smoking cessation has become synonymous with Champix. Every smoker today, thinks about Champix when he wants to quit smoking. Especially because of smoking ban, being introduced in many countries, the popularity and demand of Champix is on a constant rise.
