Montreal, September 29, 2008 – 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.

Dr. O'Loughlin added that this inter-university investigation builds on previous findings: "Exposure to second-hand smoke among non-smokers may cause symptoms that seem to reflect several nicotine withdrawal symptoms: depressed mood, trouble sleeping, irritability, anxiety, restlessness, trouble concentrating and increased appetite."
