If you smoke--particularly cigarettes--you are far more likely than a non-smoker to suffer or die from several major diseases--notably lung cancer.

One smoker in four dies prematurely (過早地) because of his smoking. The risk of dying for a heavy smoker (between the ages of 35 and 55) is roughly equal to the risk run by a non-smoker 10 years older.

Cigarette smoking--and to a lesser degree pipe and cigar smoking-may aggravate(使惡化)or be partly responsible for the development of a wide variety of other diseases, which include

cancers of the mouth and throat, peptic ulcers (胃潰瘍), and loss of teeth.

Women who smoke during pregnancy produce babies on average about 5 to 8 ounces lighter than those who don't.

Take lung cancer for example:

Britain's lung cancer figures are the highest in the world, and still rising. Ninety people die every day, 33,000 in 1969. Almost all these deaths can be attributed directly to tobacco smoking.

The prospects of a cure for lung cancer are, at present, remoter ,and it is impossible to estimate when, if ever, someone will find one. You would be foolish to rely on someone finding a cure before you needed it.

One man in eight who die between the ages of 35 and 64 is killed by lung cancer. The figures for women in this age group are lower, about 1 in 20. This is partly because women smoke less, and have not smoked as long. But the figures are still very high.
