It will shortly be illegal for adults in Ireland to smoke in cars where children are passengers, with fines of around €80 to be imposed for breaking the law.
The ban is particularly timely in light of new research indicating that non-smoking people, who sit in parked cars with smokers, inhale some of the same cancer-causing substances and other toxins.
Simply by sitting in cars with smokers, passengers breathe in a host of potentially dangerous compounds from tobacco smoke that are associated with cancer, heart disease and lung disease.
The study in the journal Cancer, Epidemiology, Biomarkers & Prevention involved testing the urine of 14 people who sat in the back seat of a parked sports vehicle while a person in the driver's seat smoked three cigarettes over an hour.
