Why Young People Start Smoking

start each year.
* Everyday in the U.S. 6,000 teens light up their first cigarette and
another 3,000 teens become regular smokers.
* Approximately 9 in 10 adults began smoking as teens and continue
into adulthood, unable to stop.
*Of those, one-third will eventually die from smoke-related causes.
About 2.6 million packs of cigarettes are sold illegally to minors in
this country everyday.
Why Teens Smoke
Some teens believe that puffing on a
cigarette will remove their fears or
insecurities.
They mistakenly believe it will make them
seem older or more sophisticated then they
are.
They start because of peer pressure or
because of advertising.
They believe they can drop the habit any time
they want.
Nicotine Is Addictive
• Like all addictive drugs, nicotine affects the brain and
other parts of the body and leads to physical
dependence and addiction.
• Quitting tobacco use is difficult and withdrawal is
unpleasant, but the dangerous effects of tobacco are
far worse than the trials of quitting.
What is in Cigarettes
There are at lease 43 chemicals in cigarettes that are
known to cause cancer. Among these are cyanide,
arsenic, and formaldehyde.
Tobacco contains nicotine, the addictive drug in
cigarettes. People smoke to reduce the craving for
nicotine, a poisonous stimulant.
Nicotine raises blood pressure and increases heart rate.
The flavor in a cigarette is due mostly to the tar in
tobacco. Tar is a sticky, dark fluid produced when
tobacco is burned.
What is in Cigarettes (cont)
Tar contains several substances known as
carcinogens, cancer-causing substances.
Carbon monoxide is a colorless, odorless, poisonous
gas in cigarette smoke that passes through the lungs
into the blood. This is the same gas in automobile
exhaust fumes that, if inhaled, could prove fatal. It unites
with the hemoglobin in red blood cells, preventing them
from carrying the oxygen needed for energy to the
body’s cells.
Smokeless Tobacco

Tobacco that is sniffed through the nose or

and gums, and damage to the digestive system.
