Get phone counseling and 6 months of Chantix at no cost to you.

Our Program

Fit & Quit is a research study through the University of Tennessee Health Science Center in Memphis. Fit & Quit is designed to help you quit smoking and stay healthy doing it.

This research study is testing three different weight management strategies in order to determine which is the best approach to help participants quit smoking AND manage their weight. With an evidence-based smoking cessation program that includes support, phone counseling and six months of Chantix, we provide the tools you need to succeed.
