According to the CDC. 40% of non-smokers
are exposed to secondhand smoke. View
The report states that
secondhand smoke is particularly dangerous in children increasing the
number and severity of asthma attacks and middle ear infections. Exposure
of children to secondhand smoke range from 11.7% in Utah to 34.2% in
Secondhand smoke contains over 50 known carcinogen (causes cancer) and causes lung cancer and heart
disease in non-smoking adults. Evidence indicates that there is a 25% to
30% increase in the risk of coronary heart disease from exposure to
In 2005 it is estimated that secondhand smoke kills 3000 non-smoking
adults from lung cancer, 46,000 from coronary disease and 430 newborns
from sudden infant death syndrome.
If you are worried about free radicals and take antioxidants. You

Secondhand Smoke and Heart Disease
Smoke free ordinance in
Pueblo Colorado reduced hospitalizations for Heart Attacks between 2002
and 2006 by 27%. Most other studies followed patients for one year
of less. This study shows a sustained effect for the health

By far one of the greatest
risk from exposure to secondhand smoke is to the heart and its effects
may have been greatly underestimated. It has been generally shown
that a non-smoker living with a smoker has a 25% increased chance of
developing heart disease.
Whincup P.H. et. al. (BMJ 329:200-205, 2004)
found that heavy passive smoking (top three exposure quarters) had the
same risk of developing major coronary artery disease as light active
smoking (1-9 cigarettes per day).
Sargent, R.P.et. al. (BMJ 328:997-980, 2004)reported that in Helena Montana, during a six month smoking ban in pubic
workplaces, that the number of admissions for acute myocardial
infarction fell significantly. Admissions fell from a total of 40
the year before to 24. This was significant at a 95% confidence
Pechacek T.F. and Babb S (BMJ 328:980-983)reported that even small exposures to tobacco smoke increase the risk of
ischemic heart disease (heart attack). The mechanism This is
felt to be caused by inflammation, thrombosis and endothelial
The risk for heart disease
is non-linear and even small exposures causes a significant risk.
Passive smoke exposure equal to 0.2 cigarettes per day causes a 30%
increase in the rise of a heart attack in the passive smoker. At 5
cigarettes per day there is a 50% increase. It takes more than 30
cigarettes per day to produce a is a 100% increase in risk. Thus,
most of the risk is incurred early one with low exposure levels.

Also, smoking during pregnancy (in utero) has also been associated with
the development of asthma in the children.

Because of secondhand smoke, each year

6.4 million people currently younger than 18 will die prematurely from a
tobacco-related disease. View Reference - ALA
Pregnant women who smoke are more
likely to have babies who have an increased risk of death from sudden
infant death syndrome and respiratory distress. They are also more
likely to have low birth-weight babies; low birth weight is linked to
many infant health disorders. View Reference - CDC
In children, exposure to
secondhand smoke has been associated with lower respiratory illness and
increasedrates of middle ear effusion, asthma, and sudden
infant deathsyndrome. Second hand smoke can also worsen
sinusitis in children and effect the recovery after sinus surgery.
Ramadan et. al. has shown that children exposed to second hand smoke in
their homes had a 70% chance of a successful surgery as children who lived
in a smoke-free environment had a 90% chance of a successful surgery.
