You might be shocked that one in every two smokers will die of a tobacco related disease. But how do we know?
The evidence comes from a study which is often called “The Doctors Study” which started in 1951 in the UK, had a 40 year follow-up, and was finally published in 1994. It showed that half of all regular cigarette smokers will eventually be killed by tobacco smoking.
Smoking is the single biggest cause of cancer and chronic obstructive pulmonary disease - a group of debilitating respiratory conditions that cause breathing difficulties. It is also a cause of heart disease and stroke. On average smokers die 10 years younger than non-smokers.
