Why Is Smoking Bad For You?
Reference: Medical News Today

Smoking is responsible for several diseases, such as cancer, long-term (chronic) respiratory diseases, and heart disease, as well as premature death. Over 440,000 people in the USA and 100,000 in the UK die because of smoking each year. According the US CDC (Centers for Disease Control and Prevention), $92 billion is lost each year from lost productivity resulting from smoking-related deaths .Of the more than 2.4 million deaths in the USA annually, over 440,000are caused by smoking.

Smoking is the largest cause of preventable death in the world. Recent studies have found that smokers can undermine the health of non-smokers in some environments. In an article published online in Medical News Today on 30 May 2013, we presented data demonstrating that, on average, smokers die ten years sooner than non-smokers. Smoking causes cancer

90% of lung cancer patients developed their disease because of smoking. Lung cancer is one of the most common causes of cancer deaths in the world. Smokers also have a significantly higher risk of developing: Bladder cancer

Kidney cancer
Cancers of the pharynx and larynx (throat cancer)
Mouth cancer
Esophagus cancer
Cancer of the pancreas
Stomach cancer
Some types of leukemia
Cancer of the nose and sinuses
Cervical cancer
Bowel cancer
Ovarian cancer
In some cases, also breast cancer
According to Cancer Research UK, one person dies every 15 minutes in Great Britain from lung cancer. Smoking also raises the risk of cancer recurrences (the cancer coming back). Why does smoking raise cancer risk?

Scientists say there are over 4,000 compounds in cigarette smoke. A sizeable number of them are toxic - they are bad for us and damage our cells. Some of them cause cancer - they are carcinogenic.

Tobacco smoke consists mainly of:
Nicotine - this is not carcinogenic. However, it is highly addictive. Smokers find it very hard to quit because they are hooked on the nicotine. Nicotine is an extremely fast-acting drug. It reaches the brain within 15 seconds of being inhaled. If cigarettes and other tobacco products had no nicotine, the number of people who smoke every day would drop drastically. Without nicotine, the tobacco industry would collapse.

Nicotine is used as a highly controlled insecticide. Exposure to sufficient amounts can lead to vomiting, seizures, depression of the CNS (central nervous system), and growth retardation. It can also undermine a fetus' proper development. Carbon Monoxide - this is a poisonous gas. It has no smell or taste. The body finds it hard to differentiate carbon monoxide from oxygen and absorbs it into the bloodstream. Faulty boilers emit dangerous carbon monoxide, as do car exhausts.

If there is enough carbon monoxide around you and you inhale it, you can go into a coma and die. Carbon monoxide decreases muscle and heart function, it causes fatigue, weakness, and dizziness. It is especially toxic for babies still in the womb, infants and individuals with heart or lung disease. Tar - consists of several cancer-causing chemicals. When a smoker inhales cigarette smoke, 70% of the tar remains in the lungs. Try the handkerchief test. Fill the mouth with smoke, don't inhale, and blow the smoke through the handkerchief. There will be a sticky, brown stain on the cloth. Do this again, but this time inhale and the blow the smoke through the cloth, there will only be a very faint light brown stain.

Recent developments on smoking from MNT news
'Approximately 14 million major medical conditions in US due to smoking' Approximately 14 million major medical conditions attributable to smoking are suffered by American adults, according to the estimates of a new study. This figure is significantly larger than figures that have been previously reported.
