A non-communicable disease is a disease that cannot spread to any other person in a community from a person who has it; it remains with the person who has it.
Heredity can play a role in a person acquiring a non-communicable but it remains within the family.
1. Tobacco use
Smokers die about 10 years earlier than never-smokers, they have twice the risk of heart disease, 10 times the risk of lung cancer, several times the risk of cancer of the mouth, throat, oesophagus, pancreas, cervix, kidney and bladder.
The following health problems also occur more in smokers:-stroke, peptic ulcers, fractures and cataract.
Nicotine, one of the major constituents of cigarette smoke is highly addictive and produces withdrawal symptoms if discontinued. This is what makes it difficult for smokers to quit.
