The findings support the need for public health interventions that promote non-smoking in the presence of children. Many experts go even further, saying that a law that would ban smoking in homes can have a significant effect in protecting children. It is known that in families where at least one parent smokes, children have a level of cotinine (a toxic metabolite of nicotine) five times higher than normal.
According to recent statistics, 53,800 people die every year from second-hand smoke exposure.

According to a joint study from nine Canadian institutions published last year, 5 percent of children who had never smoked a cigarette, but who were exposed to secondhand smoke in cars or their homes, reported symptoms of nicotine dependence, even though they had never smoked. It is vital that pregnant women are made aware of the possible risks associated with third hand smoke, the researchers said, adding that the particles in cigarettes are known to significantly increase the risk of pregnancy complications.
