Illness caused by smoking Smoking has more than 50 ways of making life a misery through illness and more than 20 ways of killing you. In general, smokers endure poorer health than non-smokers. It has been estimated that, in England, 364,000 patients are admitted to NHS hospitals each year due to diseases caused by smoking. This translates into 7,000 hospital admissions per week, or 1,000 day. [1] In 1997/98, cigarette smoking caused an estimated 480,000 patients to consult their GP for heart disease, 20,000 for stroke and nearly 600,000 for COPD. 1
Half of all teenagers who are currently smoking will die from diseases caused by tobacco if they continue to smoke. One quarter will die after 70 years of age and one quarter before, with those dying before 70 losing on average 21 years of life. [2] It is estimated that between 1950 and 2000 six million Britons, 60 million people worldwide, would have died from tobacco-related diseases. [3]
Non-lethal illness Smokers face a higher risk than non-smokers for a wide variety of illnesses, many of which may be fatal (see “Deaths caused by smoking” below). However, many medical conditions associated with smoking, while they may not be fatal, may cause years of debilitating illness or other problems. These include: [4]
Deaths caused by smoking One in two long-term smokers will die prematurely as a result of smoking – half of these in middle age. The most recent estimates show that around 114,000 people in the UK are killed by smoking every year, accounting for one fifth of all UK deaths. [6] Most die from one of the three main diseases associated with cigarette smoking: lung cancer, chronic obstructive lung disease (bronchitis and emphysema) and coronary heart disease. The table below shows the percentage and numbers of deaths attributable to smoking, based on the latest available detailed breakdown (2002 data).
* Studies have shown that smoking appears to have a protective effect against the onset of some diseases such as endometrial cancer. However, the positive effect is so small in comparison with the overwhelming toll of death and disease caused by smoking that there is no direct public health benefit.
Deaths caused by smoking are five times higher than the 22,833 deaths arising from: traffic accidents (3,439); poisoning and overdose (881); alcoholic liver disease (5,121); other accidental deaths (8,579); murder and manslaughter (513); suicide (4,066); and HIV infection (234) in the UK during 2002. 7 World-wide, almost 5 million die prematurely each year as a result of smoking. Based on current trends, this will rise to 10 million within 20 years. [8]
