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.

NICOTINENicotine 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 SystemIncreases activity level• Mimics neurotransmitters• Decreases some reflex actions• Activates the brain’s “reward pathway”

Cardiovascular system

• Increases heart rate and the 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

Respiratory System•Increases mucus production• Decreases muscle action in the lungs’ airways• Causes breathing to become more shallow

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

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.
