Summary
This study tested whether taking the smoking-cessation drug varenicline for 4 weeks before quitting (instead of the usual 1 week) helps more people stay smoke-free. 320 smokers were randomly assigned to either the extended or standard pre-quit schedule, and all received counseling and 11 weeks of post-quit varenicline. The main goal was to see if the extended group had higher rates of confirmed abstinence at the end of treatment and at 6 months.
