Researchers examined the impact of state-level policies on adolescent use of Electronic Nicotine Delivery Systems (ENDS) from 2013-2019, including smokefree laws and minimum legal sales age laws that applied to ENDs and tobacco excise tax laws. The study used data from the Population Assessment of Tobacco and Health and the Americans for Nonsmokers’ Rights Foundation and included adolescents aged 12-17. They found that the odds of adolescent ENDS use were 21.4% lower when the state had an ENDS minimum sales age restriction and 55.0% lower when the state had a comprehensive law that also prohibits the use of e-cigarettes than in the years when the state did not have the smokefree law. “Wider implementation of policies may help intervene in youth vaping,” the authors concluded. Read the paper.
