Smoking increases the risk of death from many causes

Most of us have heard that smoking damages the lungs. The chart drives this home: in the US, men who smoke are around 21 times more likely to die from lung cancer than men who have never smoked.

But the damage doesn’t stop there: smoking also increases the risk of other cancers, including mouth, throat, bladder and pancreatic cancer, in addition to other health conditions such as chronic obstructive pulmonary disease (COPD), heart disease, and diabetes.

Why does one habit harm so many organs? Cigarettes carry a mixture of carcinogens that reach — and damage — tissues throughout the body. Smoking also injures blood vessels, fuels inflammation, and makes it easier for tumors to spread.

Because a single behavior poses so many risks, cutting smoking rates has been one of the most powerful tools to save lives and improve public health.
