Secondhand Smoke Exposure

Unborn children are vulnerable to secondhand smoke exposure. Smoking during pregnancy has been linked to low birth-weight and Sudden Infant Death Syndrome (SIDS). Other conditions thought to be linked to exposure to secondhand smoke include miscarriages and an adverse impact on cognition and behaviour in children.


In 2014, 12.1%  (11.4%, 13.3%) of Simcoe Muskoka mothers that gave birth reported smoking at the time of their newborn’s birth. Of the new mothers that smoked, the majority (60.1% (56.0%, 64.0%)) smoked less than 10 cigarettes per day and approximately one in three (30.8% (27.1%, 34.7%)) smoked 10-20 cigarettes per day.
