Ð''Cardiovascular' means the heart and circulation.

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 700Ð'oC at the tip and around 60Ð'oC 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:

Ð'* tar, a carcinogen (substance that causes cancer)

Ð'* nicotine is addictive and increases cholesterol levels in your body

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

Major diseases caused by smoking

Cardiovascular disease

Cardiovascular disease is the main cause of death due to smoking.

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.
