Cigarette smoke has 70 carcinogens

Smokers and passive smokers (within 1 meter) are susceptible to chronic diseases of the lungs, respiratory tract, and many other diseases, which can lead to cancer.

Smoking is harmful to most human body organs. Professor Robert West, director of the British Cancer Research Institute , said it only takes a few seconds of tobacco smoke to reach the lungs, making the heart work harder and increasing blood pressure. Cigarette smoke stimulates and causes respiratory infections, which can persist forever after the first hissing.

Cigarette smoke causes cancer.

The US Food and Drug Administration (FDA) places nicotine in the 'drug' group, which primarily affects the central nervous system, leading to addiction.

Nicotine is colorless, turns brown when burned, absorbed through the skin, mouth and nasal mucosa or inhaled directly into the lungs. Carbon monoxide (CO), a colorless, odorless gas, the concentration of tobacco smoke is 600 times higher than permitted, will be absorbed into the blood, the conjugation reaction with hemoglobin is 20 times more potent than oxygen.

Each time the medicine hissed, CO went straight into the blood, it pushed oxygen molecules out of red blood cells. Oxygen levels only return to normal lungs after 6 hours stop smoking. In cigarette smoke there are up to 70 carcinogens, such as carcinogenic benzopyren aromatic compounds, chronic inflammation, organizational destruction, cell changes leading to dysplasia, malignant dysplasia and malignancy.

Risk of passive smoking: Adults can get lung cancer and other diseases. Children, very susceptible to cigarette smoke, should be prone to chronic bronchitis with acute episodes, diseases of the ears, nose, throat, headaches, affecting the brain, heart and intestines, especially is hypertension in boys.

The highest concentration of carcinogens such as polycyclic aromatic hydrocarbons (PAH) after smoking for 15 - 30 minutes.
