Parents who smoke cigarettes around their kids in cars and homes beware – second-hand smoke may trigger symptoms of nicotine dependence in children.
“Increased exposure to second-hand smoke, both in cars and homes, was associated with an increased likelihood of children reporting nicotine dependence symptoms, even though these children had never smoked,” says Dr. Jennifer O’Loughlin, senior author of the study.

Study participants were recruited from 29 Quebec schools as part of AdoQuest, a cohort investigation that measures tobacco use and other health-compromising behaviours.
