OF SECOND HAND SMOKE
out of ten nonsmokers (40%) are
exposed to secondhand smoke.
More than 1 out of 2 kids (aged 3–11
years) are exposed to secondhand smoke.
There are about 1.3 billion cigarette
smokers worldwide and this number is
About 1 in 5 adults smoke.
Tobacco use is the leading preventable
cause of death.
Nonsmokers inhale mostly sidestream (SS) smoke.
The 'side-stream' smoke that comes off a cigarette
between puffs, carries a higher risk than directly
Second-hand smoke is a mixture of sidestream smoke
and the smoke exhaled from the lungs of smokers.
It is involuntarily inhaled, lingers in the air for hours
after cigarettes have been extinguished.
Second hand smoke may cause a wide range of
adverse health effects, including:
Cancer (Increased lung cancer risk (by 20–30%))
Reduced lung growth in children
Reductions in postnatal pulmonary function
Increased heart disease risk (by 25–30%)
Chronic otitis media
Second-hand smoke has been estimated to cause
38,000 deaths per year, of which 3,400 are deaths
from lung cancer in non-smokers.
For adults, passive smoking seems to increase
the risk of lung cancer.
Sidestream smoke has higher concentrations of
cancer-causing agents (carcinogens) than
Children who grow up in a home where one or
both of their parents smoke have twice the risk of
getting asthma and asthmatic bronchitis.
Children also have a higher risk of developing
Infants under two years old are more prone to
severe and cot death (SIDS).
Exposure to environmental smoke causes
reduced lung growth in children.
Second hand smoke results in to reductions in
postnatal pulmonary function.
HEART DISEASE RISK
The current US Surgeon General’s Report
Short exposures to second-hand smoke
Blood platelets to become stickier
Damage the lining of blood vessels
Decrease coronary flow velocity reserves
Reduce heart rate variability
Increased risk of heart attack
Fetal exposure to carbon monoxide and nicotine
Increased risk of abruptio placentae, placenta previa, and premature
rupture of the membranes and ectopic pregnancy
delivery, low birth weight, are also more likely among
who smoke should quit smoking or at least reduce the
number of cigarettes smoked per day to as few as possible.
women should also avoid exposure to environmental
smoke ("passive smoking") and smokeless tobacco.
Environmental tobacco poisoning, either second or third
hand, dramatically increases pulmonary morbidity.
Smoking family members should be advised to quit
smoking and do everything possible to minimize
environmental smoke exposure to the children around
