Q: I know that smoking
is bad for a person's health. Just how bad is it? A: About as bad
as it could get. Smoking is one of the most important causes of disease and is
responsible for at least one out of every five deaths in the
United
States. Compared to
nonsmokers, smokers have 10 times the risk of getting lung cancer -- and twice
the risk of dying from heart disease. Smoking also causes chronic lung disease
-- chronic bronchitis and emphysema -- which can be fatal. But that's not all.
As research continues, the list of diseases associated with smoking keeps
growing longer. That list now includes stroke, peptic ulcer, osteoporosis, and
cataracts, as well as cancer of the mouth, throat, esophagus, pancreas, kidney,
bladder, uterus, cervix -- and possibly also leukemia and cancer of the breast,
prostate, and colon. In addition, diabetics who smoke increase their risk of
kidney disease. Smoking can interfere with the healing of wounds and fractures.
And it increases facial wrinkling, making a person look older than he or she
really is.
Q: Isn't cigar smoking
less of a risk to health than cigarette smoking? After all, most cigar smokers
don't inhale. A: This is
largely a myth, and a dangerous one. Medical research has shown that cigar
smoking increases a person's risk of heart disease and cancer -- especially
mouth, throat, and lung cancer. That's not really surprising once you know that
cigar smoke contains the same toxic and cancer-causing chemicals as cigarette
smoke (and is just as addictive), that smoking four or more cigars in a day is
the equivalent of smoking at least 10 cigarettes, and that a single large cigar
contains as much tobacco as a pack of cigarettes. What's more, "mainstream"
cigar smoke (the smoke drawn into the mouth) contains more of many toxic and
cancer-causing chemicals than cigarette smoke does. Even cigar smokers who don't
inhale are exposed to their own environmental or passive smoke -- which has been
proved to be a risk factor for heart and lung disease -- and just holding an
unlit cigar in your mouth can cause nicotine to be absorbed into your body.
Q: What about chewing
tobacco? Is it safe? A: No. Holding
chewing tobacco in your mouth can cause toxic chemicals to be absorbed into your
body. In addition, people who chew tobacco have an increased risk of developing
mouth cancer.
Q: What is "passive"
or "secondhand" smoking? A: These terms
refer to the smoke you breathe in from other people's cigarettes, cigars, or
pipes -- or your own smoke, such as when you're holding a lit cigarette and
inhaling the smoke indirectly. When you breathe other people's smoke, even if
you're not smoking yourself, in a way you might as well be -- because the smoke
is going into your lungs, too.
Q: I know that
cigarette and cigar smoke can cause disease in smokers. How harmful is passive
smoke? A: Recent studies
have shown small but significant increases in risk of coronary heart disease,
lung disease, and cancer among nonsmokers exposed to cigarette and cigar smoke
-- a risk that increases with higher levels and longer duration of smoke
exposure. Passive smoke has also been linked with development of lung cancer,
heart attack, low birth weight, sudden infant death syndrome (SIDS), bronchitis,
pneumonia, asthma, chronic respiratory problems, eye and nasal irritation, and
middle ear infection. Children are particularly at risk for the effects of
passive smoke.
Q: I just got
pregnant, and I smoke. Is it true that smoking can hurt the baby? Should I
stop?
A: You're probably aware that smoking can hurt you, mainly by greatly
increasing your risk of developing lung cancer and heart disease. So you should
stop smoking to protect your own health as well as your baby's. When a pregnant
woman smokes, she exposes her baby to the toxic chemicals in cigarette smoke,
including more than 40 cancer-causing agents. In addition, medical research
studies have shown that pregnant women who smoke increase their risk of such
serious problems as miscarriage, stillbirth, premature birth, low-birth-weight
babies, and lower intelligence in the children they are carrying. There are even
studies showing that male children of mothers who smoke during pregnancy are
more likely to become criminals when they grow up! Tell your obstetrician you
smoke, and follow his or her advice on what you can safely do to stop -- and
improve your chances of having a healthy pregnancy and a healthy baby.
Q: What's so wrong
with a teen-ager experimenting with smoking? A: What's wrong
is that cigarette smoking isn't just bad for your health, it's also addictive.
Most teen-agers underestimate their risk of becoming "hooked" on cigarettes --
until it's too late. The truth is, among high school seniors who smoke for 1 to
5 cigarettes a day, a full 70% will still be smoking -- and risking their health
-- 5 years later. Even people who have smoked as few as 100 cigarettes report
that they can't quit smoking. So why take the risk of starting? Remember, the
happy, carefree young people you see in cigarette advertisements more closely
resemble people who don't smoke.
Q: What's being done
to stop teen-age smoking? A: A number of
different approaches are being taken. First, there are legal restrictions -- it
is illegal to sell cigarettes or other tobacco products to minors under age 18.
Store clerks are required by law to ask young adults for proof of age -- and
enforcement has sometimes included "compliance checks" in which
government-employed minors (under adult supervision) attempt to buy tobacco
products. Second, more and more states and communities are putting programs into
action to persuade young people not to smoke. These often include school-based
education, media campaigns, and youth community action. Third, it's important to
realize that reducing adult smoking can also help reduce teen-age smoking. A
recent study showed that teen-agers who live in smoke-free homes -- and/or have
jobs in smoke-free workplaces -- are significantly less likely to smoke than
those whose home or work environments have no smoking restrictions. These
findings suggest that one of the most important things parents can do to prevent
their teen-agers from smoking is to keep their home smoke-free.
