When your parents were young, people could buy cigarettes and smoke pretty much anywhere —
even in hospitals! Cigarette commercials were all over the place. Today we're more aware about
how bad smoking is for our health. Smoking is restricted or banned in almost all public places and
cigarette companies are no longer allowed to advertise on TV, radio, and in many magazines.
Almost everyone knows that smoking causes cancer, emphysema, and heart disease; that it can
shorten your life by 10 years or more; and that the habit can cost a smoker thousands of dollars a
year. So how come people are still lighting up? The answer, in a word, is addiction.
Once you start, it’s hard to stop
People start smoking for a variety of reasons. Some think it looks cool. Others start because their
family members or friends smoke. Statistics show that about 9 out of 10 tobacco users start before
they're 18 years old. Most adults who started smoking in their teens never expected to become
addicted. That's why people say it's just so much easier to not start smoking at all.
