Cigarettes and Tobacco
Tobacco is a green, leafy plant that is grown in warm climates. After it is picked, it is dried, ground up, and used in different ways. It can be smoked in a cigarette, pipe, or cigar. It can be chewed (called smokeless tobacco or chewing tobacco) or sniffed through the nose (called snuff).
Smoking effects almost every organ of the body. Smoking can cause many diseases and reduces the health of smokers in general. More deaths are caused each year by tobacco use than by all deaths from human immunodeficiency virus (HIV), illegal drug use, alcohol use, motor vehicle injuries, suicides, and murders combined. The adverse health effects from cigarette smoking account for an estimated 443,000 deaths, or nearly one of every five deaths, each year in the United States.
Percentage of U.S. adults who were current smokers in 2010
•19.3% of all adults (45.3 million people)
•31.4% non-Hispanic American Indian/Alaska Native
•25.9% non-Hispanic multiple race
•21.0% non-Hispanic white

The definition of carcinogens is the substance capable of causing cancer in living tissue.
In 2004 over 5 and a half billion cigarettes were smoked.
Effects of smoking
Effects of Smoking on the Body
Trouble with blood circulation
Lessened glowing of your skin
Lessened ability to smell the lovely flowers
Lessened lung capacity
Less oxygen for your brain
The risk of developing lung cancer is about 23 times higher among men who smoke cigarettes and about 13 times higher among women who smoke cigarettes compared with never smokers.
Cigarette smoking increases the risk for many types of cancer, including cancers of the lip, oral cavity, pharynx, esophagus, pancreas, larynx (voice box), lung, uterine cervix, urinary bladder, and kidney.
Rates of cancers related to cigarette smoking vary widely among members of racial/ethnic groups but are highest among African-American men.
Smoking causes coronary heart disease, the leading cause of death in the United States. Cigarette smokers are 2–4 times more likely to develop coronary heart disease than nonsmokers.
Cigarette smoking approximately doubles a person's risk for stroke.
Cigarette smoking causes reduced circulation by narrowing the blood vessels (arteries). People who smoke have a much greater risk of developing peripheral vascular disease than nonsmokers.
Smoking causes abdominal aortic aneurysm.
Secondhand smoke exposure causes heart disease and lung cancer in nonsmoking adults.
Nonsmokers who are exposed to secondhand smoke at home or work increase their heart disease risk by 25–30% and their lung cancer risk by 20–30%.
COPD, Chronic bronchitis, and Emphysema
COPD' (chronic obstructive pulmonary disease) used to describe lung damage resulting in airflow restriction.
Chronic bronchitis is a chronic inflammatory condition in the lungs that causes the respiratory passages to be swollen and irritated, increases the mucus production and damages the lungs.
In emphysema, there is a slightly different problem developing in the lungs as the walls between the tiny grape-shaped air sacs or alveoli are damaged and break down. They then form into much larger airspaces and there is less surface for gas exchange, so oxygen intake is less and the person feels breathless.
Second Hand smoke
smoke is also known as environmental tobacco smoke (ETS) or passive smoke.
Types of Second hand Smoke
Secondhand smoke comes from both the smoke that smokers exhale (called mainstream smoke) and the smoke floating from the end of the cigarette, cigar, or pipe (called sidestream smoke).
In children aged 18 months or younger, secondhand smoke exposure is responsible for...
an estimated 150,000–300,000 new cases of bronchitis and pneumonia annually, and
· approximately 7,500–15,000 hospitalizations annually in the United States.
Stats on Second hand Smoke and Disease
Tobacco smoke contains more than 7,000 chemical compounds. More than 250 of these chemicals are known to be harmful, and at least 69 are known to cause cancer.
About 3,400 lung cancer deaths in non-smoking adults.
· Between 150,000 and 300,000 lower respiratory tract infections (lung and bronchus) in children under 18 months of age, with 7,500 to 15,000 hospitalizations each year.
In the United States, the costs of extra medical care, illness, and death caused by SHS are over $10 billion per year.
Nicotine is a highly addictive stimulant found
in tobacco that is quickly absorbed into the bloodstream when smoked.
Nicotine decreases your appetite, increases
heart rate, cognitive arousal, and decrease in tension.
withdrawal creates anxiety, irritability, headache, hunger, and a craving for
cigarettes or other sources of nicotine.
