Tobacco Tracker: A New Tool to Support College Smoke and Tobacco Free Policies.

Tobacco Tracker is a promising tool for college communities to support smoke and tobacco free (STF) policy through active surveillance of smoking, vaping, and related litter on campus. Introduction of Tobacco Tracker was associated with changes in social enforcement-related attitudes and behaviors critical to realizing the preventive potential of STF policies. A crowdsourcing-based tool for monitoring tobacco use on college campuses can address a major barrier to social enforcement: discomfort confronting tobacco users. Further, it provides an alternative to punitive enforcement approaches and promises a sustainable solution to an infrastructure issue faced by many universities lacking resources to collect data on campus tobacco use and related litter.
