Cash for quitting: couples who smoke together get paid to kick the habit
NCT ID NCT06296849
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether offering money to couples who both smoke can help them quit. About 900 couples will be split into three groups: one gets standard quit-smoking help, another adds rewards for the main smoker, and a third rewards both partners. The goal is to see if rewarding both partners works better and is worth the cost.
