Tobacco Overview

-Cigarettes-Cigars

-Chew tobacco

Tobacco

There are approximately 4,000 chemicals in a single cigarette

There are approximately 10,000 chemicals in a single cigar

So, which one is worse? Cigarettes!

At least 56 of these chemicals are known to be carcinogenic.

Carcinogens – chemicals that are known to cause cancer.

TobaccoWhere did these carcinogens come from?

What is second hand smoke?

Pesticides – bug spray

Second hand smoke has: 2 x the nicotine5 x the carbon monoxide 98 x the ammonia 3 x the benzopyrene as mainstream smoke.

Environmental tobacco smoke kills 53,000 people annually or 124 people each day – remember, these are non-smokers.

TobaccoWhat is the addictive ingredient?

An injection of one drop (70mg) will kill an average size man within a few minutes.

Nicotine – currently the most addictive substance that humans are aware of.

Nicotine in plants acts as a natural anti-herbivore chemical that discourages insects from eating the plant. Nicotine is pale yellow in color and is oily in consistency. Upon contact with air nicotine turns brown and is extremely poisonous in high concentrations. Nicotine acts as a stimulant when ingested by mammals and this is the reason why many people have a dependence on it.

Tobacco is the only product that when used as directed results in death and disability.

Tobacco

98% of smokers will be lifetime users. About 2% will ever be able to quit for good.

12% of people get addicted on first time use.

Each marijuana joint equals 4 – 7 cigarettes.

Tobacco - conditions

Alcohol

Arteriosclerosis: a hardening of the arteries. It is also a major cause of heart attack and stroke. Four main things that lead to arteriosclerosis:

Tobacco

Lack of exercise

Fatty foods, poor nutrition

Tobacco - conditions

Stroke: lack of blood flow to the brain, due to a blockage in a blood vessel or the bursting of a blood vessel.

Heart Attack: caused when the heart is damaged by a sudden lack of blood flow to the heart muscle.

Tobacco - conditionsemphysema:

When you breathe, air is drawn in through the bronchial passages and down into the increasingly fine network of tubing in the lungs called the alveoli, which are many thousands of tiny sacs surrounded by capillaries. These absorb the oxygen and transfer it into the blood. When toxins such as smoke are breathed into the lungs, the particles are trapped by the hairs and cannot be exhaled. Instead, they remain in the lungs, clogging up the oxygen exchange mechanism and severely restricting the airflow. This damage causes the symptoms of emphysema.

Emphysema is an irreversible degenerative condition. It is treated by supporting the breathing with bronchodilators and steroid medication, and supplemental oxygen is often required.

Emphysema

Tobacco - conditionsCirculatory Issues:

Smoking causes blood vessels to become narrow, reducing blood flow to the various organs and parts of the body.

Tobacco - conditionsUlcer:

An ulcer is a sore or hole in the stomach. Nicotine in cigarette smoke causes extra stomach acid to form. This extra acid can lead to an ulcer. Smoking can prevent this from healing.

Tobacco – other conditions

Gingivitis

Halitosis: extremely bad breath

Headaches

Osteoporosis

Allergies

Lung: 85% of all lung cancers are caused by smoking.

Leukoplakia: early stage oral cancer.

Your body (immune system) has 3 major lines of defense:1. SKIN: as long as your skin is intact, your risk of infection is relatively non-existent.

2. MUCUS MEMBRANES: this is why your eyes water, nose runs, etc., when you get sick. It’s your body’s way of trying to keep your system free of germs.

3. FEVER: when something gets past your skin and mucus membranes you run a fever.

Cilia is part of the 2nd line of defense. These tiny, hair-like fibers are constantly sweeping debris up and out of your system.(eyelashes, etc)

TAR causes significant problems for cilia. It temporarily paralyzes it.

Your body (immune system) has 3 major lines of defense:

Because the cilia can no longer function effectively, mucus that would normally be expelled is now pooling in the lungs.

Someone who smokes a pack-a-day for a year, has generated 4 cups of TAR.1/3 of that stays in the tobacco filter 1/3 goes into the lungs of the smoker1/3 goes into the air as second hand smoke

Someone who smokes a pack a day for a year, has to clear about 2 cups of mucus out of their lungs every morning.
