Smoking and Lung Cancer
Smoking can have harmful impacts on lung function. Cigarette smoke contains harmful chemical such as nicotine, carbon monoxide and carcinogens (cancer-causing chemicals).

Bronchitis
- When smoke is breathed in, it damages the cilia cells of the airways.
- This means the cilia can't waft away the mucus produced by goblet cells, and the mucus builds up.
- This can lead to bronchitis, where the airways are partly blocked with mucus.

Cancers
- The carcinogens can cause tumours to form in the airways.
- Smoking can cause mouth, throat and lung cancers.

Emphysema
- Smoke damages the walls of the alveoli, reducing their surface area.
- This can cause emphysema, where gas exchange can't happen efficiently, causing shortness of breath.

Heart disease and strokes
- Nicotine is very addictive and puts strain on the heart.
- Carbon monoxide reduces the ability of red blood cells to carry oxygen, which can also put strain on the heart.
- Both of these substances can cause heart disease and strokes.
