What is Tobacco smoking? <br />Tobacco smoking is the practice where tobacco is burned and the vapors either tasted or inhaled. The practice began as early as 5000–3000 BC. The substance was met with frequent criticism, but became popular. <br />Smoking is the most common method of consuming tobacco, and tobacco is the most common substance smoked. The agricultural product is often mixed with other additives and then pyrolyzed. The resulting vapors are then inhaled and the active substances absorbed by the lungs. The active substances trigger chemical reactions in nerve endings which heightens heart rate, alertness and reaction time. Dopamine and later endorphins are released, which are often associated with pleasure.<br />

The invention of the cigarette-rolling machine in 1881 accelerated the mass-production of pocket sized packets of cigarettes. <br />In the current era of economic globalization, some forms of tobacco, historically localized to specific regions of the world have spread to every continent. For instance, Indonesian kreteks—clove-flavored, loosely packed tobacco cigarettes—are currently being marketed to youth in many countries. <br />There is no safe way to use tobacco—whether inhaled, sniffed, or chewed; whether some of the harmful ingredients are reduced; or whether it is mixed with other ingredients. <br />
