Tobacco Basics


Tobacco: A South American herb (Nicotiana tabacum) whose leaves contain 2 to 8 percent nicotine and serve as the source of both smoking and smokeless tobacco  )
There are over 4,000 chemicals in a cigarette. (http://www.tricountycessation.org/tobaccofacts/Cigarette-Ingredients.html)
Over 3,800 people start smoking every day(http://www.cdc.gov/tobacco/data_statistics/fact_sheets/fast_facts/)
Carcinogen: cancer causing
There are 81 known cancer causing chemicals in a cigarette. (http://www.whyquit.com/whyquit/A_Tobacco_Additives.html)

Effects of Smoking

10 effects of smoking on the body: Irritation of the trachea (windpipe) and larynx (voice box)
Reduced lung function and breathlessness due to swelling and narrowing of the lung airways and excess mucus in the lung passages
Impairment of the lungs’ clearance system, leading to the build-up of poisonous substances, which results in lung irritation and damage Increased risk of lung infection and symptoms such as coughing and wheezing
Permanent damage to the air sacs of the lungs.
Raised blood pressure and heart rate
Constriction (tightening) of blood vessels in the skin, resulting in a drop in skin temperature
Less oxygen carried by the blood Stickier blood, which is more prone to clotting
Damage to the lining of the arteries, which is thought to be a contributing factor to atherosclerosis (the build-up of fatty deposits on the artery walls)
Reduced blood flow to extremities like fingers and toes Increased risk of stroke and heart attack due to blockages of the blood supply. (http://www.betterhealth.vic.gov.au/bhcv2/bhcarticles.nsf/pages/Smoking_effects_on_your_body)
Illnesses are more severe and it takes longer to get over them.
Cancer is the second leading cause of death and was among the first diseases causally linked to smoking. (http://quitsmoking.about.com/od/tobaccostatistics/a/cancerstats.htm)
Smoking's effects on the lungs, such as the development of emphysema and lung cancer, are mainly caused by tar and nicotine. (http://www.allsands.com/health/smokingeffects_srw_gn.htm)
Smoking makes the blood more likely to clot. These clots can travel in your bloodstream until they finally become stuck in one of the blood vessels in your brain, cutting off blood flow and triggering a stroke. (http://www.hearthealthywomen.org/am-i-at-risk/smoking/smoking-page-2.html)
People who smoke have a two to four times higher chance of having heart disease. (http://www.webmd.com/smoking-cessation/quit-smoking-heart)
Chronic obstructive pulmonary disease (COPD) is one of the most common lung diseases. It makes it difficult to breathe. There are two main forms of COPD:
Chronic bronchitis, which involves a long-term cough with mucus
Emphysema, which involves destruction of the lungs over time
(http://www.ncbi.nlm.nih.gov/pubmedhealth/PMH0001153/)

Passive smoking is the inhalation of smoke, called second-hand smoke (SHS), or environmental tobacco smoke (ETS), by persons other than the intended 'active' smoker. It occurs when tobacco smoke permeates any environment, causing its inhalation by people within that environment.

Sidestream smoke – smoke from the lighted end of a cigarette, pipe, or cigar
Mainstream smoke – the smoke exhaled by a smoker

SHS has been linked to lung cancer. There is also some evidence suggesting it may be linked with childhood leukemia and cancers of the larynx (voice box), pharynx (throat), brain, bladder, rectum, stomach, and breast.
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. http://www.cancer.org/cancer/cancercauses/tobaccocancer/secondhand-smoke

Second Hand Smoke

Addictive Potential

Nicotine, one of more than 4,000 chemicals found in the smoke from tobacco products such as cigarettes, cigars, and pipes, is the primary component in tobacco that acts on the brain. Chronic exposure to nicotine results in addiction
Nicotine also increases the level of other neurotransmitters and chemicals that modulate how your brain works. For example, your brain makes more endorphins in response to nicotine

Among current U.S. adult smokers, 68.8% report that they want to quit completely, and millions have attempted to quit smoking
