Sponsor's own description
This study tested whether positive messages on tobacco packaging about the mental health benefits of quitting smoking could help motivate people to stop smoking. It compared three types of labels: ones focusing on mental health benefits, ones focusing on physical health benefits, and blank labels. The experiment involved 631 people who smoke who were randomly shown one of these label types on an online survey platform. Participants' motivation to quit smoking was measured before and after viewing the labels.
