Summary
This study will assess the impact of cigarette constituent messages with and without FDA source and quit information in a randomized controlled trial. The investigators hypothesize that cigarette constituent messages will increase intention to quit compared to messages about littering cigarettes (the control). The investigators also hypothesize that constituent messages that include FDA source and quit information will increase intention to quit compared to messages without that information.
