Exposure to Secondhand Smoke in Homes and Vehicles Among U.S. Youths, United States, 2011–2019

Although progress has been made in enacting comprehensive smoke-free indoor air laws in public settings, private settings such as homes and vehicles remain major sources of secondhand smoke (SHS) exposure for some populations, including youth. The adverse health effects of SHS exposure from combustible tobacco products are well established; there is no risk-free level of SHS exposure. This study reports the prevalence of self-reported SHS exposure in homes and vehicles among U.S. middle and high school students in 2019, and changes in SHS exposure over time.  In 2019, 25.3% (6.7 million) of  U.S. middle and high school students reported home SHS exposure, and 23.3% (6.1 million) reported vehicle SHS exposure. SHS exposure in homes and vehicles significantly declined during 2011 through 2018, except for SHS exposure in homes among non-Hispanic Black students. Implementation of smoke-free policies in both public and private settings, including homes and vehicles, can help reduce SHS exposure, particularly among youth.
