'Passive smoking' describes the involuntary inhalation of
other peoples' tobacco smoke.
It may take the form of either 'mainstream smoke' inhaled
and exhaled by the smoker, or 'sidestream smoke' emitted directly
from burning tobacco.
The term 'environmental tobacco smoke' refers to the combination
of sidestream and exhaled mainstream smoke in the atmosphere.
The unborn child is passive smoking when the mother is a
smoker or is exposed to smoke. This is because the baby receives
tobacco by-products though the mother's bloodstream.
These by-products include nicotine and carbon monoxide. Nicotine
increases the baby's heart rate and the carbon monoxide takes
the place of the oxygen in the blood, leaving less oxygen
for the baby.
