How does smoking affect our lungs?
Smoking is harmful to our bodies in many ways,
but it is the most harmful to the lungs.
Smoke from cigarettes contains tar,
which sticks to the cilia in our
lungs. The cilia usually act like little
brooms to sweep out harmful dirt,
but when you smoke cigarettes, the
cilia can't work because they're
covered in sticky tar. That means
that dirt can stay in the lungs and
cause problems.
Even if you don't smoke, your lungs are still in
danger if you breathe in smoke from another
person's cigarette. This is called second-hand
smoke, and it is as dangerous as smoking the
cigarette yourself! That's why you should always
try to stay away from smokey places. Keep your
lungs healthy and stay away from cigarette
smoke!
Do you know that tobacco kills more people in
Canada each year than car accidents, suicides,
murder, AIDS, and drug use all together? 100
Canadians quit smoking every day... because
they die. Don't fall into the same trap they did!
Smokers get seriously ill
more easily than non-
smokers. Some of these
sicknesses are bronchitis,
emphysema, lung cancer,
and heart disease!
Most of these sicknesses are
a result of damage to the cilia (the little brooms)
in the lungs. Without the cilia working, the dirt-
filled mucus slides down into your lungs and
blocks the tiny airways so that the air can't get in
and out! You may notice that people who smoke
seem to cough a lot. This is because they have to
cough to get rid of the dirty mucus in their lungs.
People who have healthy lungs hardly ever need
to cough, because we have those great cilia
working to get that dirt out!
Smoking is Bad for health bt although some people smoking 
Well, government warnings and information for bad effect of smooking would not stop smookers not unless they change their way of thinking.
