Health effects

Smokers generally experience more anxiety, stress and depression than non-smokers.

Smoking is also a major cause of stroke. Strokes occur when an artery carrying blood to the brain suddenly becomes blocked, causing part of the brain to die. This can cause loss of movement, vision or speech.

Smokers are 1.5 to 2 times more likely to have a stroke, with heavier smokers even more at risk.
On average, people who quit smoking experience a 40% increase in positive emotions.

Benefit of quitting

Five years after quitting smoking, your risk of stroke has significantly reduced.

You’re also more likely to reduce your stress levels by becoming a non-smoker.



Health effect

Smoking causes coronary heart disease and increases the risk of other heart and blood vessel diseases. Blockages in certain arteries can lead to heart attack and reduced blood supply to the heart can cause permanent damage to heart muscles.

A year after quitting smoking, your risk of coronary heart disease is about half that of someone who continues to smoke.


Health effect

Smoking causes lung cancer. It’s the leading cause of cancer deaths in Australia.

Irritants in cigarette smoke can damage the air sacs in the lungs and cause emphysema. Over time, this makes breathing difficult, with some smokers becoming breathless even after minor exertion.

For a life-long smoker, the risk of lung cancer is 20 times higher than for a life-long non-smoker.
90% of lung cancer cases in men are caused by smoking.
65% of lung cancer cases in women are caused by smoking.
