Abstract
England banned smoking in cars carrying children in 2015 and Scotland in 2016. We used survey data from 3 years for both countries (N<sub>England</sub>=3483-6920, N<sub>Scotland</sub>=232-319) to assess effects of the English ban using logistic regression within a difference-in-differences framework. Among children aged 13-15 years, self-reported levels of regular exposure to smoke in cars for Scotland were 3.4% in 2012, 2.2% in 2014 and 1.3% in 2016 and for England 6.3%, 5.9% and 1.6%. The ban in England was associated with a -4.1% (95% CI -4.9% to -3.3%) absolute reduction (72% relative reduction) in exposure to tobacco smoke among children.
