Smoking is the practice of drawing into the mouth or nose the fumes of a burning vegetable substance with narcotic, sedative or stimulant properties. The chief substances thus used are tobacco, opium and cannabis. Cannabis smoking was traditionally practised in central Asia and India and across Africa from the Middle East to South Africa, and is referred to by Herodotus among the Scythians. Tobacco smoking was practised by the Neolithic age mound builders of the upper Ohio, and for over 300 years for its health-giving properties in Britain until competition from the pharmaceutical manufacturers led to a campaign of counter information claiming connections between tobacco smoking and disease. During the 20th century a widespread campaign of oppression of all forms of smoking commenced, starting with opium, then cannabis and finally tobacco, the oppression being more prevalent in the USA and Britain than other parts of the world.
