Most people know that smoking can cause lung cancer, but it can also cause many other cancers and illnesses.
Smoking kills around 114,000 people in the UK each year.
Of these deaths, about 42,800 are from smoking-related cancers, 30,600 from cardiovascular disease and 29,100 die slowly from emphysema and other chronic lung diseases.
How do cigarettes damage health?
Cigarettes contain more than 4000 chemical compounds and at least 400 toxic substances.
When you inhale, a cigarette burns at 700ÐoC at the tip and around 60ÐoC in the core. This heat breaks down the tobacco to produce various toxins.
As a cigarette burns, the residues are concentrated towards the butt.
The products that are most damaging are:
tar, a carcinogen (substance that causes cancer)
nicotine is addictive and increases cholesterol levels in your body
carbon monoxide reduces oxygen in the body
components of the gas and particulate phases cause chronic obstructive pulmonary disorder (COPD).
The damage caused by smoking is influenced by:
the number of cigarettes smoked
whether the cigarette has a filter
how the tobacco has been prepared.
Smoking affects how long you live
Research has shown that smoking reduces life expectancy by seven to eight years.

Non-smokers and ex-smokers can also look forward to a healthier old age than smokers.

Hardening of the arteries is a process that develops over years, when cholesterol and other fats deposit in the arteries, leaving them narrow, blocked or rigid. When the arteries narrow (atherosclerosis), blood clots are likely to form.
Smoking accelerates the hardening and narrowing process in your arteries: it starts earlier and blood clots are two to four times more likely.
Cardiovasular disease can take many forms depending on which blood vessels are involved, and all of them are more common in people who smoke.
