This study seeks to assess the effectiveness of the QuitTXT program, a text message cessation intervention designed for young adult smokers ages 18-29. The QuitTXT program is a component of a larger web-based tobacco cessation intervention resource provided by the National Cancer Institute. The program focuses on providing actionable strategies and fact based information, serving as an engagement tool delivering two-way communication, and delivering intra- and extra-treatment support. The structure of the QuitTXT program is designed as a 14-day countdown to quit date with subsequent six weeks of messages. Throughout the program, users will receive texts that cover a variety of content areas including tips, informational content, motivational messaging, and keyword responses.
