What’s in a cigarette

Nicotine: The addictive drug
in tobacco leaves.

Tar: Is a thick, sticky, dark
fluid produced when tobacco burns.
This tar consists of many cancer causing
substances known as carcinogens
 Stimulant: Is a drug that increases
the action of the central nervous system
What’s in a cigarette


Carbon Monoxide: Is a colorless, odorless,
poisonous gas in cigarette smoke that
passes through the lungs and into the
blood.
The gas deprives the body’s tissues and
cells of oxygen. It increases the risk of high
blood pressure, heart disease and other
circulatory problems.
Statistics from the American Lung
Association





Cigarette smoke contains over 4,800 chemicals, 69 of
which are known to cause cancer.
Secondhand smoke involuntarily inhaled by nonsmokers
is responsible for approximately 3,000 lung cancer
deaths annually.
Approximately 1,100 kids become new, regular daily
smokers each day.
Stats from US News
An older brother/sister that smokes raises the risk that
the younger sibling will smoke by 6 times.
Children of ex smokers or current smokers were found
to have a 23-29% chance of becoming a smoker.
Short-Term Effects




Brain chemistry changes: Nicotine causes
the body to crave more of the drug. Users
can experiences withdraws as soon as 30
minutes after last tobacco use
Respiration & heart rate increases
Taste buds are dulled & appetite is reduced
Yellow teeth and smelly hair, skin, &
clothes.

Long Term Effects


A weakened immune system
Coronary heart disease and stroke

Arteriosclerosis: hardening of the arteries due to
plaque build up from nicotine.
The Healthy Lung

Anatomy & Physiology
of the lungs.
Chronic Bronchitis

Chronic bronchitis: is
the inflammation and
eventual scarring of the
lining of the bronchial
tubes. As the cilia
become useless, tar
from cigarette smoke
builds up, which results
in coughing and
excessive mucus
secretion.
Pulmonary Emphysema

In emphysema, the
fine dividing walls
between the tiny air
sacs break. The sacs
balloon out to become
large pockets of air
with hard inflexible
walls.
Lung Cancer

Cancer is an area of
uncontrolled cell
growth that invades
the surrounding tissue
and destroys it. This
is due to the build up
of tar in the lungs.

Pulmonary Emphysema
