The British Medical Journal published the results of a survey on smoking by researchers from the British Cancer Institute, the Wolfson Institute for Preventive Medicine at the University of London and the Hong Kong University of Science and Technology, which found that smoking significantly increases people's risk of cardiovascular disease, but has little to do with the amount of cigarettes smoked.

Smoking 20 cigarettes a day increases the risk of coronary heart disease by 127% in men and 295% in women.

But smoking even one cigarette a day increases the risk of coronary heart disease by 74% in men and 119% in women.

In other words, the risk of coronary heart disease from smoking one cigarette a day is about half that of smoking 20 cigarettes a day.

Studies have shown that 80% of lung cancers are related to smoking. The amount of cigarettes smoked is linearly associated with an increased risk of lung cancer.

But even smoking just one cigarette a day is associated with a very high risk of lung cancer and cardiovascular disease.

According to statistics, nearly half of all smoking-related deaths are due to cardiovascular diseases, and nearly half of the people die from lung cancer. And obviously in life, many people ignore the risk of cardiovascular disease caused by smoking.

Therefore, there is no "safety line" for smoking, and the only solution to eliminate the health effects of smoking is to quit smoking completely.

According to a study in the United Kingdom, smoking a cigarette can kill a person's life by 11 minutes, and if you smoke 20 cigarettes a day, you may lose 3 hours and 40 minutes of life.

This estimate is based on a man who started smoking at age 17 and died at an average age of 71, assuming that he smokes 15 cigarettes a day like the average British addict and will consume 311688 cigarettes in his lifetime. On average, smokers will die six and a half years earlier than non-smokers.

Nicotine is an addictive drug that is absorbed by the lungs and mainly acts on the nervous system. Carbon monoxide reduces the ability of red blood cells to transport oxygen throughout the body.

A person who smokes 15 to 20 cigarettes a day is 14 times more likely to die from lung, mouth or throat cancer than a non-smoker. They are 4 times more likely to die from esophageal cancer than non-smokers; The chances of dying from bladder cancer and heart disease are 2 times greater.
