Tobacco use is the leading cause of preventable
death and disability in the United States.
Health Risks of Tobacco Use
Any form of tobacco use, such as smoking,
chewing, or dipping tobacco, can cause health
problems.
Smoking has been linked to lung disease, cancers,
and heart disease.
Health Risks of Tobacco Use
About 90 percent of
adult smokers
began the habit as
teenagers.
It’s easier to avoid
tobacco use rather
than quit later.
Nicotine
Tobacco users have difficulty quitting because
tobacco contains an addictive drug.
Addictive drug
A substance that causes physiological
or psychological dependence
Nicotine
All tobacco products contain nicotine.
Nicotine
The addictive drug found in
tobacco leaves
Nicotine
Nicotine is a stimulant that raises blood pressure
and increases the heart rate.
Stimulant
A drug that increases the action
of the central nervous system,
the heart, and other organs
Poisonous Substances in Tobacco Smoke
Tobacco is an addictive and toxic drug and a
carcinogen.
Carcinogen
A cancer-causing
substance
Tar
Cigarette smoke contains tar.
Tar
A thick, sticky, dark fluid
produced when tobacco burns
Tar
paralyzing and
destroying cilia
Tar damages
a smoker’s
respiratory
system by
destroying the
alveoli
damaging lung
tissue
Carbon Monoxide
Carbon monoxide is also in cigarette smoke. It
deprives the body’s tissues and cells of oxygen.
Carbon monoxide
A colorless, odorless, and
poisonous gas
Pipes, Cigars, and Smokeless Tobacco
No tobacco product is safe to use.
The dangers of tobacco use are not limited to
smoking cigarettes.
Pipes, Cigars, and Smokeless Tobacco
Cigarette filters do not
protect smokers from
more than 50
carcinogens, including
cyanide and arsenic,
which are in tobacco
products.
Pipes, Cigars, and Smokeless Tobacco
The smoke from pipes and cigars also causes
serious health consequences.
Cigars contain significantly more nicotine and
produce more tar and carbon monoxide than
cigarettes.
Pipes, Cigars, and Smokeless Tobacco
The harmful chemicals of smokeless tobacco are
absorbed into the body at levels up to three times
the amount of a single cigarette.
Smokeless tobacco
Tobacco that is sniffed
through the nose, held in the
mouth, or chewed
Pipes, Cigars, and Smokeless Tobacco
Using smokeless tobacco also irritates the
sensitive tissues of the mouth, causing
leukoplakia.
Leukoplakia
Thickened, white, leathery-looking
spots on the inside of the mouth
that can develop into oral cancer
Harmful Effects of Tobacco Use
Tobacco use causes both short-term and
long-term damage to your body.
Health officials have warned the public about the
dangers of tobacco use for several decades.
Short-Term Effects
