According to the Center for Disease Control, there is no risk-free level of exposure to second hand smoke. Secondhand smoke can cause negative health effects, such as health problems in infants and children, like asthma, respiratory infections, ear infections, and can cause Sudden Infant Death Syndrome. According to the CDC, smoking during pregnancy causes 1000 infant deaths each year. Coronary heart disease, lung cancer, and stroke are potential health risks for adults exposed to secondhand smoke.

My mother's parents both smoked, and she and some of her siblings have had asthma their entire lives. If you still smoke, do you ever smoke outside to prevent these risks for your family members?
