Perceived Comparative Harm of Cigarettes and Electronic Nicotine Delivery Systems
Menée aux Etats-Unis en 2017 et 2018 par enquêtes auprès de 10 802 adultes, cette étude compare leurs perceptions des dangers de la cigarette électronique et de la cigarette classique
Scientific evidence on the health risks associated with using electronic nicotine delivery systems (ENDS) is rapidly evolving. Perceived harm of ENDS is also changing rapidly. The percentage of US adults, including current smokers, who perceive using ENDS as equally or more harmful than smoking cigarettes increased between 2012 and 2015, with rates stable through 2017. Comparative harm perceptions are important factors associated with smokers’ decisions to use ENDS and have implications for population health. This study uses data from late 2018 to assess changes in US adults’ comparative harm perceptions of ENDS and cigarettes after a year characterized by intense public debate and regulatory efforts to restrict youth access to ENDS.
