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.

Use page 402 403 to define some 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

neurotransmitters Decreases some reflex
actions Activates the brains reward pathway
Effects of Nicotine

the force of contractions Increases blood
pressure Reduces blood flow to skin Increases
risk of blood clotting

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.
