Smoking is harmful to health.

As we all know, smoking is harmful to health.

A cigarette, which includes more than 4000 kinds of different chemical substances, there is one of 43 kinds of carcinogenic substances are, so every cigarette smoking, but also that 4000 kinds of inhaled chemical substances, so that shorten the life span of 5 ~ 15 minutes. The following is a list

The composition of cigarettes and health, appearance and image of the impact of:

Types of health effects of cigarette ingredients

 Nicotine

 1. Cause addictive ingredients.

 2. Each one cigarette containing 1.5 mg nicotine, of which 24 percent of smokers smoke directly from absorption, inhalation time as 60 to 70 mg will cause death.

 3. Nicotine increased blood viscosity, so that the accumulation of cholesterol in the blood vessels to increase the chances of vascular occlusion.

 4. High blood pressure, rapid heart beat.

 5. To increase gastric acid secretion, gastric ulcer risk smokers.

 6. Impede the delivery of oxygen.

Carbon monoxide

1. Monoxide slow down blood circulation, so that the accumulation of fat, vascular occlusion, increasing the chance of coronary heart disease.

2. Long-term inhalation of carbon monoxide, will lead to oxygen in the blood fell, gas velocity is easy to reduce the exercise and speed up aging. Substantial inhalation can cause heart, brain and other organs appeared hypoxia.

Carcinogenic effects of smoking

Chinese in 2006, "Smoking and Health," the report pointed out that since the 50's since the 20th century, the global scope of a large number of epidemiological studies have confirmed that smoking is the primary cause of lung cancer risk factors of death due to lung cancer patients, 87% by smoking (including passive smoking) caused. Male smokers of lung cancer mortality rate of non-smokers are 8 ~ 20 times. In addition, the incidence of smoking and lung cancer in a dose - response relationship, more than 25 daily smokers, lung cancer incidence rate of ten thousand 227/10; 15 ~ 24 for the ten thousand 139/10; 1 ~ 14 million for 75/10 . Lung cancer risk of death increased their cigarette and has increased year by year.

Of smoking on the heart, the brain blood vessels against

Many studies confirm that smoking is a lot of heart, cerebrovascular disease, one of the major risk factors. Smokers, hypertension, coronary heart disease, cerebrovascular disease and peripheral vascular disease were significantly higher morbidity. Statistics show that the incidence of coronary heart disease than non-smokers and smokers, the high-3. 5-fold, coronary heart disease mortality in the former than the latter high 6 times. The incidence of myocardial infarction in the former than the latter 2-6 times as high, pathological autopsy also found that coronary atherosclerotic lesions the former than the latter broad and serious. Hypertension, hypercholesterolemia and smoking were the three with an increase in the incidence of coronary heart disease 9 -12 times. Smokers more prone to coronary heart arrhythmia, the occurrence of increased risk of sudden death.

Hazards of passive smoking

Passive smoking than to smoke a lot more harmful substances inhaled, smokers out cold smoke, tar than cigarette smokers inhale hot smoke one many times, many Benzopyrene 2 times, carbon monoxide more than 4 times. 2 interior tobacco smoke pollution 20 times higher than outdoors, with a smoker living with cancer the opportunity to increase 1.4 times, with two smokers living with cancer the opportunity to increase 2.3 times. Epidemiological investigation showed that the husband of the female smoking prevalence rate for the husband's lung cancer non-smokers 1.6 - 3.4 times. According to an international sample survey confirmed that smoking cancer patients 50% are passive smokers.

Smoking is harmful to health, we must vigorously promote smoking in public places. At the individual not to smoke or smoke less. This benefit our health!
