Cigarette smoke contains:
- Nicotine: an addictive drug, which raises blood pressure, narrows arteries and veins and damages the heart. Over time, this slows the blood flow in the body, decreasing oxygen supply to the peripheries e.g. hands and feet.
- Carbon monoxide: A gas that takes oxygen supply away from your heart and body. Over time, the airway paths in the lungs swell, which restricts the amount of air that can get into the lungs.
- Tar: Contains many dangerous chemicals that may either cause cancer or trigger other substances to cause cancer. Over time, tar clogs the lungs, restricting airflow.
- Phenols: These are hazardous chemicals that kill the hair-like cells found in the bronchus and bronchioles (airway paths). Over time, the body loses the ability to "sweep" mucous and other particles from the lungs and airways, leading to congestion.
- Fine particles: These irritate the throat and lungs. Over time, a "smoker's cough" develops, with more mucous produced as more damage is done to the lungs.
Cigarette smoking causes disease and ill-health:
- Poor blood circulation
- Breathing problems
- Hearing loss
