Please Stop Smoking!!!
« on: July 26, 2007, 01:17:40 PM »
Tobacco is a plant grown for its leaves, which are smoked, chewed, or sniffed for a variety of effects. It is considered an addictive substance because it contains the chemical nicotine.

In addition to nicotine, tobacco contains over 19 known cancer-causing chemicals (most are collectively known as "tar") and more than 4,000 other chemicals. These include acetone, ammonia, carbon monoxide, cyanide, methane, propane, and butane.

THE EFFECTS OF NICOTINE

Nicotine acts as both a stimulant and depressant on your body. It increases your bowel activity, saliva, and bronchial secretions. It stimulates the nervous system and may cause tremors in the inexperienced user, or even convulsions with high doses.
After stimulation, there's a phase that depresses the muscles in your airways. As a euphoric agent, nicotine causes relaxation from stressful situations.
On average, tobacco increases your heart rate 10 to 20 beats per minute, and it increases your blood pressure reading by 5 to 10 mmHg (because it constricts the blood vessels).
Nicotine may also cause sweating, nausea, and diarrhea. Nicotine elevates the blood level of glucose (blood sugar) and increases insulin production. Nicotine also tends to enhance platelet aggregation, which may lead to blood clots .
Nicotine temporarily stimulates memory and alertness. People who use tobacco frequently depend on it to help them accomplish certain tasks at specific levels of performance. Nicotine also tends to be an appetite suppressant. (For this reason, fear of weight gain also influences the willingness of some people to stop smoking.)
Finally, tobacco is highly addictive. It is considered mood and behavior altering. Tobacco is believed to have an addictive potential comparable to alcohol, cocaine , and morphine.

HEALTH RISKS

There are many reasons to quit using tobacco. Knowing the serious health risks may help motivate you to quit. When used over a long period, tobacco and related chemicals such as tar and nicotine can increase your risk of:

Blood clots , which may lead to aneurysms and strokes
Cancer (especially in the lung, mouth, larynx, esophagus, bladder, kidney, pancreas, and cervix)
Coronary artery disease , including angina and heart attacks
Decreased ability to taste and smell
Delayed wound healing
High blood pressure
Lung problems such as emphysema and chronic bronchitis
Pregnancy-related problems, including miscarriage, premature labor, low birth weight, and risk for sudden infant death syndrome ( SIDS )
Tooth and gum diseases
You have the same risks if you use smokeless tobacco (chewing tobacco, snuff, etc.) for a long time. In addition, smokeless tobacco users have a 50 times greater risk for mouth cancer than those who do not use such products.

SECONDHAND SMOKE

Those who are regularly around the smoke of others (secondhand smoke) have a higher risk of:

Coronary artery disease
Lung cancer
Sudden and severe reactions, including those involving the eye, nose, throat, and lower respiratory tract
Infants and children that are exposed regularly to secondhand smoke are at risk of:

Asthma
Infections, including virus-caused upper respiratory infections, ear infections, and pneumonia
Lungs that do not work as well (poor lung function)
Sudden infant death syndrome (SIDS)
