Chapter 18

Tobacco use

Is the number one cause of preventable disease and is associated with the leading causes of various chronic conditions as well as death

10 worst diseases smoking causes

Lung cancer; COPD (Chronic Obstructive Pulmonary Disease); heart disease; stroke; asthma; reproductive effects in women; premature, low-birth weight babies; diabetes; blindness, cataracts and age-related macular degeneration; over 10 other types of cancer

Lung Cancer

More people die from lung cancers than any other; cigarette smoking is the number one risk factor for lung cancer, responsible for 87% of lung cancer death; being alive 5 years after being diagnosed is less than 1 in 5

COPD

Chronic Obstructive Pulmonary Disease

COPD

Makes it hard to breath and usually gets worse; 80% of COPD caused by cigarette smoking; third leading cause of death in U.S.

Heart Disease

Number 1 cause of death in U.S

Stroke

Cause paralysis, slurred speech, altered brain function and death; 4th leading caused of death in U.S; Leading cause of adult disability

Asthma

Affects close to 25 million Americans

Reproductive Effects in Women

Ectopic pregnancy and reduced fertility

Diabetes

30% to 40% of developing type 2 diabetes for smokers, increase risk of heart and kidney disease, and poor blood flow to legs and feet

Blindness, Cataracts, and Age-Related macular degeneration

Leading cause of blindness in adults ages 65 and older

10 other types of cancer

More likely to develop a second primary cancer; liver and colorectal cancer; reduces the survival rates for prostate cancer patients

Adults in the U.S that smoke

42 million, 18%

Worldwide death annually from smoking

6 million; 8 million by year 2030

Tobacco smoke

Contains both gases and particulates and limits mow much oxygen can be carried in the bloodstream

The particulate phase of burning tobacco includes

A variety of carbon-based compounds or carcinogens

Nicotine

More addictive than heroin or alcohol; affects the brain and alters mood and behavior

When smoke is inhaled

Nicotine reaches the brain in 7 seconds

The responses throughout the body when nicotine is inhaled and reaches the brain

Heart and breathing rates increase, blood vessels constrict, peripheral circulation slows down, blood pressure increases

First time smokers may experience

Dizziness, nausea, headache, feelings of tension and tiredness relieved

After a few minutes

Withdrawal occurs; may feel depressed, irritable, and have the urge to smoke again

Chewing tobacco forms

Loose leaf, twist, plug, dip, chew, or chaw

Smokeless tobacco contains

7 times more nicotine than cigarettes

Between 80% to 90%

Of all deaths related to lung cancer and obstructive lung disease are caused by smoking

Risk for coronary disease and stroke

Two to four times higher among smokers

A review on tobacco and dementia by the WHO

14% of Alzheimer's disease cases worldwide may link to smoking

Exposure to secondhand smoke can increase

The risk for dementia

By reducing serum cholesterol to recommended levels can increase

Life expectancy by about 1 week to 6 months

Smoking cessation may increase

Life expectancy by 2.5 to 4.5 years

The cost of human life, smoking in the U.S

$170 million in health-care expenditures which accounts for 8.7% of total health-care spending

Unhealthy Effects of Smoking

Eyes; lungs; kidneys, colon, liver, bladder, pancreas; stomach/abdomen; mouth/throat; heart; reproductive system; blood; brain

Eyes

Cataracts and macular degeneration

Lungs

Lung cancer, bronchitis, emphysema, tuberculosis, pneumonia, and asthma

Kidneys, colon, liver, bladder, and pancreas

Cancer and diabetes

Stomach/Abdomen

Stomach cancer, peptic ulcers, and abdominal aortic aneurysm

Mouth/Throat

Cancers of the mouth, throat, larynx, and esophagus and causes gum disease

Heart

Coronary artery disease and atherosclerosis

Reproductive system

Breast cancer, cervical cancer, erectile dysfunction, birth complications, unhealthy babies, and sudden infant death syndrome in babies of smokers

Blood

Impairs immune system, leukemia, and decrease HDL

Brain

Stroke

Several factors determine the dosage of tobacco usage

The number of cigarettes smoked, the length of time one has been smoking, the strength of the cigarette, the depth of the inhalation, the amount of exposure to other lung-damaging substances, and the greater the exposure to smoke, the greater the risk

3 physical consequences of short-term smoking

Increased rates of respiratory infections and asthma, impairments of athletic performance, and reduce benefits and enjoyment associated with recreational exercise

Cigar and pipe smokers have a higher risk for

Cancer of the mouth, throat, larynx, and pipe smokers: lip

Secondhand smoke

A combination of mainstream and sidestream smoke

Adolescents exposed to secondhand smoke

May have five times the risk of developing metabolic syndrome, increasing the risk of heart disease, stroke, diabetes, and becoming smokers

Children of smoking mothers have

Lower birth weight, more likely to be premature, at risk for respiratory infections and asthma, attention-deficit/hyperactivity, and Sudden Infant Death Syndrome (SIDS)

Exposure to secondhand smoke in both childhood and adulthood can increase

Risk for depression and panic disorder 10 years later

11 Health Risks of Smokeless Tobacco

Oral cavity cancer (increases by 4 to 50 times); cancer of throat, larynx, and esophagus; precancerous skin changes; high blood pressure; rotting teeth, exposed roots, premature tooth loss, and worn-down teeth; ulcerated, inflamed, infected gums; slow hea
