Tobacco

Tobacco contains many harmful substances that damage your body when you smoke or chew it. The main dangerous component is nicotine, which is highly addictive and makes your heart beat faster while raising your blood pressure. Tar is another harmful substance that builds up in your lungs and causes cancer. Carbon monoxide, the same poisonous gas in car exhaust, gets into your bloodstream and reduces oxygen in your body.

When you see someone smoking cigarettes on the streets of Lagos or in any Nigerian city, that person is inhaling all these toxic components. Tobacco also contains over 4,000 other chemicals, many of which cause serious diseases like lung cancer, heart disease, and stroke.

Understanding these components is crucial because examiners love asking students to identify which parts of tobacco cause specific health problems.

Smoking damages nearly every organ in your body because tobacco contains harmful substances like nicotine and tar. When you smoke, these chemicals enter your lungs and bloodstream, causing serious problems over time. Your lungs get damaged, making it hard to breathe, while your heart has to work harder, increasing the risk of heart attack and stroke.

Smoking also causes cancer in the lungs, mouth, and throat. Many Nigerians develop these diseases from smoking cigarettes or using traditional tobacco products. Your teeth become stained, your skin ages faster, and you develop a persistent cough. Secondhand smoke harms people around you too, especially children.

The effects develop gradually, which tricks people into thinking smoking is safe until serious diseases appear. Stopping smoking at any stage improves your health significantly.
