Summary

This study tests whether offering financial incentives through a mobile phone app can help low-income adults quit smoking. 532 participants will receive either standard care (phone counseling and nicotine patches/gum) or standard care plus mobile rewards for verified abstinence. Smoking status is checked using a portable carbon monoxide monitor and facial recognition. The goal is to see if the incentive program improves quit rates at 26 weeks.
