AbstractResearch on active smoking and secondhand smoke exposure has led to policy changes to protect individuals from the adverse health impacts of tobacco smoke. Despite the exten-sive literature on tobacco, only recently has there been recogni-tion that long-lived tobacco smoke components (known as Bthirdhand smoke^or THS) in indoor environments where smoking has taken placemay have adverse health consequences. This paper describes THS and addresses the challenges of limit-ing exposure to THS in vulnerable populations (e.g., non-smokers and young children). We conducted a limited survey of key stakeholders in the Los Angeles area to better understand approaches to address THS in the real estate and automobile industries. Most respondents indicated concerns about past smoking for property value and reported using various tech-niques to eliminate THS. We consider examples of other pollut-ants as case studies, including radon, asbestos, and lead, to help
frame policy directions for THS. Based on the information col-lected from stakeholders and the case studies, we offer policy approaches to managing THS. Keywords Thirdhand smoke.Nicotine.
