smoking smoking smoking is a practice in which a substance is burned and the resulting smoke is typically breathed in to be tasted and absorbed into the bloodstream. most commonly, the substance used is the dried leaves of the tobacco plant, which have been rolled into a small rectangle of rolling paper to create a small, round cylinder called a cigarette. smoking is primarily practised as a route of administration for recreational drug use because the combustion of the dried plant leaves vaporizes and delivers active substances into the lungs where they are rapidly absorbed into the bloodstream and reach bodily tissue. in the case of cigarette smoking, these substances are contained in a mixture of aerosol particles and gases and include the pharmacologically active alkaloid nicotine; the vaporization creates heated aerosol and gas into a form that allows inhalation and deep penetration into the lungs where absorption into the bloodstream of the active substances occurs. in some cultures, smoking is also carried out as a part of various rituals, where participants use it to help induce trance-like states that, they believe, can lead them to spiritual enlightenment.

smoking caused over five million deaths a year from 1990 to 2015. non-smokers account for 600,000 deaths globally due to second-hand smoke. the health hazards of smoking have caused many countries to institute high taxes on tobacco products, publish advertisements to discourage use, limit advertisements that promote use, and provide help with quitting for those who do smoke. smoking can be dated to as early as 5000 bce, and has been recorded in many different cultures across the world. early smoking evolved in association with religious ceremonies; as offerings to deities; in cleansing

attempts by chinese official lin zexu to eliminate the trade led to the outbreak of the first opium war. the chinese defeat in the first and second opium wars resulted in the legalization of the
