A study to assess the knowledge of Pre-University students regarding ill effects of smoking & tobacco chewing in a selected college in Bengaluru

Abstract

Smoking is a practice in which a substance, most commonly tobacco, is burmed and the smoke is tasted or inhaled. This is primarily practiced as a route of administration for recreational drug use, as combustion releases the active substances in drugs such as nicotine and makes them available for absorption through the lungs. It can also be done as a part ofrituals, to induce trances and spiritual enlightenment. The most common method of smoking today is through cigarettes, primarily industrially manufactured but also hand-rolled from loose tobacco and rolling paper. Other smoking implements include pipes, cigars, bidis, hookahs, vaporizers, and bongs. It has been suggested that smoking-related disease kills one half of all long term smokers but these diseases may also be contracted by non-smokers. A 2007 report states that about 4.9 million people worldwide each year die as a result of smoking.[)
