Tar: Tar is a sticky, brown residue that forms when tobacco is burned. It contains various harmful chemicals, including polycyclic aromatic hydrocarbons (PAHs) and carcinogens. Tar accumulates in the lungs and contributes to the development of lung diseases.
Carbon monoxide (CO): Carbon monoxide is a poisonous gas that is produced when tobacco is burned. It binds to hemoglobin in the blood, reducing its ability to transport oxygen throughout the body. Long-term exposure to carbon monoxide can lead to oxygen deprivation and increased strain on the cardiovascular system.
Formaldehyde: Formaldehyde is a toxic substance that is released when tobacco is burned. It is a known carcinogen and irritant to the respiratory system.
Benzene: Benzene is a volatile organic compound (VOC) found in cigarette smoke. It is a known carcinogen and is associated with the development of leukemia.
Polycyclic aromatic hydrocarbons (PAHs): PAHs are a group of chemicals that are formed when organic matter, such as tobacco, is burned. They are known to be carcinogenic and can cause DNA damage.
Ammonia: Ammonia is added to cigarettes to enhance the absorption of nicotine. It increases the speed at which nicotine is delivered to the brain, making cigarettes more addictive.
Acetone: Acetone is a solvent found in cigarette smoke. It is also used as a nail polish remover and paint thinner. Inhaling acetone can irritate the respiratory system.
Lead and cadmium: Cigarette smoke contains heavy metals such as lead and cadmium. These metals can accumulate in the body over time and have toxic effects on various organs.
Hydrogen cyanide: Hydrogen cyanide is a poisonous gas that is released when tobacco is burned. It interferes with the body's ability to use oxygen and can cause severe health problems.
*Note: It's important to note that this list represents only a fraction of the thousands of chemicals found in cigarette smoke.
