NCT01104636

Brief Summary

The aim of this study is to determine the success rates for stopping smoking with varenicline in Germany. The main measure of success will be continuous abstinence from smoking (not a single puff) in the last week of the standard 12 week treatment period. Additional information will be gathered regarding prescribing practices in Germany, smoking history, reasons why smokers quit smoking and re-start smoking, smoking related illnesses and the tolerability of varenicline.
