Study Summary
The primary purpose of this study is to determine the effects of distributing free nicotine replacement therapy (NRT) to tobacco quitline callers directly. Specifically, this study aims to: 1. Test if sending active nicotine patches directly will lead to a higher quit rate, compared to a condition where the quitline assists the smokers to obtain patches by other means (e.g. via their health plans). 2. Test if sending placebo patches directly will also lead to a higher quit rate. 3. Test if quitline counseling increases the quit rate when the smokers already receive the nicotine patches.
