(Baonghean.vn) - A cigarette contains approximately 600 ingredients. When lit, it creates more than 7,000 toxic chemicals, including hundreds that are harmful to health, 70 chemicals that are confirmed to cause cancer, and many other chemicals that are super toxic.

These are axtone (nail polish remover), ammonia (floor and toilet cleaner), DDT/Dieldrin (pesticide), Arsenic (used in rat poison), CO (automobile exhaust), Toluene (industrial solvent), Methanol formaldehyde (embalming agent)... When these substances enter the body, they will affect the entire nervous, vascular and endocrine systems, causing cardiovascular diseases, memory loss and cancer.
Scientists have identified some of the terrible toxins in cigarette smoke as being divided into four main groups:
1. Nicotine:Nicotine is an addictive substance found incigarette. The US Food and Drug Administration (FDA) classifies Nicotine as a substance with primarily addictive pharmacological properties, similar to the drugs Heroin and Cocaine.
The addictive effects of nicotine are mainly on the central nervous system, causing many neuropsychiatric effects such as euphoria, happy mood, increased attention, increased cognitive activity and short-term memory.
2. Carbon monoxide (CO gas):CO gas is present in high concentrations in cigarette smoke and is absorbed into the blood. CO gas enters the blood quickly and displaces O2(oxygen) on red blood cells. And so after smoking, a number of red blood cells in the blood temporarily lose their oxygen transport function because they have combined with CO, which is the cause of some chronic lung diseases such as: Asthma, bronchitis, bronchiectasis...
3. Small molecules in cigarette smoke:Cigarette smoke contains many irritants in gaseous and particulate form. These irritants cause structural changes in the bronchial mucosa leading to proliferation of bronchial glands and mucus-secreting cells and loss of ciliated cells.
4. Carcinogens:In cigarette smoke there are about 70 substances with carcinogenic properties.cancerThese chemicals act on the surface cells of the respiratory tract, causing chronic inflammation, tissue destruction, cell transformation leading to dysplasia, and then malignancy.
To contribute to improving the quality of life, each of us should voluntarily abstain from smoking at home, at work and in public places where smoking is prohibited; and at the same time, strongly oppose smoking in places where there are children, pregnant women and the elderly.
