Smoking and health

It is well known that tobacco smoke contains harmful substances such as nicotine, tar and carbon monoxide.  In fact, more than 7000 chemicals (e.g. cyanide, arsenic), of which at least 69 carcinogens (e.g. nitrosamine, aldehyde, chromium), were identified in the smoke. These substances will harm nearly every organ of the body and cause various diseases.

Nicotine - Addictive, narrows blood vessels
Tar - Carcinogenic, irritates airways, causes yellowish nails and teeth
Carbon monoxide - Reduces oxygen carrying capacity of blood, depletes oxygen, accelerates ageing

Evidence shows that smoking is a causative agent of many fatal diseases and cancers. It is confirmed that at least 10 types of cancer are caused by smoking. Besides, disorders and problems such as impotence, infertility, wrinkling, and halitosis can also be caused by smoking.

Cancers  Lung cancer, oral cavity and pharyngeal cancer, laryngeal cancer, oesophageal cancer, stomach cancer, liver cancer,  pancreatic cancer, bladder and kidney cancer, cervical cancer, leukemia and colorectal cancer
