Led by our partners at the University of Iowa, this study examined the social network structure of the EX Community and explored links between social network position and quitting outcomes.

We often get asked “are smokers on the Internet different from other smokers?” To answer this question, we compared the characteristics of 5,300 smokers from EX to a national dataset of smokers from the CDC.

Weight loss. Physical activity. Smoking cessation. Internet interventions of all kinds see a large proportion of “one hit wonders” (people who visit once and never return). This study explored why using data from EX.

Observational studies about the role of e-cigarettes for smoking cessation pose unique methodological challenges. This study showed that different analytic methods can yield different results.

Quitting smoking is one of the most common New Year’s resolutions. But do they stick? Using data from a large randomized trial, this study examined the impact of seasonality among users on EX.
