Our team of digital cessation experts developed This is Quitting, the first program to help young people quit vaping. This paper describes preliminary outcomes among the first 27,000 people to enroll.

Can an online community convince people to avoid drinking to improve their chances of quitting? This study applied novel social computing methods to EX Community data to find out.

Mental health problems like anxiety, depression, and substance abuse commonly co-occur with smoking and decrease the likelihood of quitting. This study of 600 smokers demonstrated the benefit of an Internet cessation program in improving quit rates among those who screened positive for depression, anxiety, and/or alcohol use disorder.

This study examined 12 years of data from the National Cancer Institute to estimate the potential population reach of Internet smoking cessation interventions. More than one third of all smokers turn to the Internet for help quitting each year, representing more than 12 million U.S. adults.

Social influence matters! Using complex social computing methods, this study showed that members of the EX community who were exposed to positive peer sentiment about NRT were more likely to use medication during their quit attempt.

User-generated content in an online community can be a rich source of information about users. Building on earlier work, this study used a novel machine learning approach to classify user-generated content from the EX Community to determine smoking status.

Do rural smokers use the Internet to quit? Yes! This study of >127,000 users of EX found that rural smokers were proportionally overrepresented on EX compared to a national dataset.

In a study of nearly 5,300 smokers on EX, use of the core components of EX significantly increased quitting outcomes at 9-months post-randomization.

This study applied a novel machine learning approach to user-generated content from the EX Community to classify smoking status among users. Implications for intervention tailoring are discussed.
