Parental Warning: Second-hand Smoke May Trigger Nicotine Dependence Symptoms In Kids 

Parents who smoke cigarettes around their kids in cars and homes beware - second-hand smoke may trigger symptoms of nicotine dependence in children.

The findings are published in the September edition of the journal Addictive Behaviors in a joint study from nine Canadian institutions.

"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, a professor at the Université de Montréal's Department of Social and Preventive Medicine and a researcher at the Centre Hospitalier de l'Université de Montréal.

"These findings support the need for public health interventions that promote non-smoking in the presence of children, and uphold policies to restrict smoking in vehicles when children are present," adds Dr. O'Loughlin, who collaborated with researchers from the Université de Sherbrooke, the Université de Moncton, the University of British Columbia, McGill University, Concordia University and the Institut national de santé publique du Québec.

Study participants were recruited from 29 Quebec schools
