Smoking cigarettes exposes the lungs to over 4000 chemicals like ammonia and acetone, which can lead to lung cancer and other health issues like mouth cancer and harm to unborn babies. Smoking is also linked to over 15,500 deaths in Australia each year and is responsible for 20% of fires. Quitting smoking can help prevent clogged arteries, premature death, and improve health for both smokers and those around them like children who are less likely to smoke if their parents do not. Doctors can provide advice and assistance to successfully quit smoking and improve life expectancy and quality of life.
