What Are Dangerous Chemicals There In The Tobacco Smoke? 

Let’s discuss the diseases caused by smoking and the various components of tobacco smoke that cause harm to the human body.

  • Tar – For various particles in the tobacco smoke, the collective term that is used is Tar. It is constituted of chemicals, and a lot of them are carcinogens (For example, benzo(a)pyrene). It stains fingernails, lung tissue and teeth as it is brown and sticky.
  • Carbon Monoxide – This gas is odorless. In large doses, carbon monoxide can cause serious harm to the human body. It can take the place of oxygen in your blood. There is a protein called hemoglobin in each blood cell. The function of hemoglobin is to transport oxygen molecules in the human body. Hemoglobin binds to carbon monoxide better than oxygen. For this reason, more red blood cells are made by our body to carry the oxygen it needs, which makes blood thicker. Less oxygen is received by our heart, brain, and other organs when the body needs more oxygen during exercise.
  • Hydrogen Cyanide – Tiny hairs called cilia are present in our lung which helps to clear out foreign objects from our lungs. Hydrogen cyanide is harmful as it can damage our lung clearance system. It can stop it from working properly which results in the building up of hazardous chemicals of tobacco smoke in our lungs. Hydrocarbons, organic acids, nitrous oxides, phenols, and oxidizing agents are some other agents that can cause harm to our lungs, both in the short term and in the long term.
  • Oxidizing Chemicals – These highly reactive chemicals can damage blood vessels, heart muscles, and some other parts of our body. The fatty material can be built up on artery walls as they react with cholesterol. Stroke, heart disease or blood vessel disease can result from oxidizing chemicals.
  • Metals – Cadmium, lead, and arsenic is some of the dangerous metals that are present in tobacco smoke. Many of these dangerous metals found in tobacco smoke are carcinogenic, that is, they can cause cancer.
  • Radioactive Compounds – Radioactive compounds are present in tobacco smoke. These compounds are carcinogenic which makes them very dangerous for the human body.
