Tobacco Products
Tobacco products are made from dried, processed leaves
of the tobacco plant. The insecticide, produced by the
tobacco plant, is nicotine which is the addictive chemical
in tobacco products. In its pure form it is very poisonous,
but in small doses is not immediately poisonous. Tobacco
users take in nicotine whenever they use tobacco
products.

True or false?
Low-tar and low-nicotine cigarettes are safer
than regular cigarettes.
Fact – although the amount of tar and nicotine in
these cigarettes may be reduced, carbon
monoxide levels are not. Also, smokers tend to
smoke more of these cigarettes and inhale more
deeply to feel the same effects as they felt from
regular cigarettes.
NICOTINE
Nicotine is a type of drug called a stimulant.
Stimulants are drugs that increase the activity of the
nervous system. Within seconds nicotine reaches
the brain mimicking the neurotransmitters and affects
breathing, movement, learning, memory, mood,
and appetite
Nervous System
Effects of Nicotine
Increases activity level
• Mimics neurotransmitters
• Decreases some reflex actions
• Activates the brain’s
“reward pathway”
Cardiovascular
system
• Increases heart rate and the
Respiratory System
•
Increases mucus production
• Decreases muscle action in the
lungs’ airways
• Causes breathing to become
more shallow
force of contractions
• Increases blood pressure
• Reduces blood flow to skin
• Increases risk of
blood clotting
Digestive system
• Increases saliva production
• Decreases the amount of
insulin released from the
pancreas
• Increases bowel activity

Dangerous chemicals in tobacco
• Tobacco smoke contains more than 4,000
hazardous compounds which enter and harm
the body.
• Most harmful chemicals found in tobacco:
– Nicotine – which we already discussed
– Tar
– Carbon monoxide
Tar
• A dark, sticky substance that forms when
tobacco burns
• Short term effects
–
–
–
–
–
–
Brown stains on fingers and teeth
Smelly hair and clothes
Bad breath
Paralysis of the cilia lining of your airways
Increased number of respiratory infections
Impaired lung functions, which lead to
reduced athletic ability
Tar contains chemicals called
CARCINOGENS that are cancer
causing agents of the body.
Carbon Monoxide
• A poisonous, colorless, odorless gas produced when
substances burn
• When carbon monoxide enters the body it takes the
place of oxygen, therefore the body cannot transport as
much oxygen it needs. This strain can damage the
cardiovascular system and other organs.
Chemicals found in
smokeless tobacco
× Smokeless tobacco contains many of the same dangerous
chemicals that are in tobacco smoke.
× Smokeless tobacco is at least as addictive as cigarettes.
× Smokeless tobacco has additional short term effects:
× Stained teeth
× Bad breath and drooling
× Receding gums and tooth decay
According to the CDC (Center for Disease Control),
Each day, more than 4,000 kids under the age of
18 try their first cigarette and another 1,100 become
regular, daily smokers. About one third of these kids
will die prematurely from a smoking-related disease.
Knowing this statistic does it challenge your decision to smoke?
Why?
It’s been said that 1 cigarette is too many but
1,000 isn't enough!!!!!
