'''పొగాకు''' లేదా '''పొగ చెట్టు''' (Tobacco) [[సొలనేసి]] కుటుంబానికి చెందిన ఒక చిన్న మొక్క. వీని నుండి [[పొగ]] విడుదలౌతున్నందు వలన దీనికి 'పొగాకు' అనే పేరు వచ్చినది. దీని ఆకుల నుండి [[సిగరెట్లు]], [[చుట్టలు]] తయారుచేస్తారు. కొన్ని రకాల తాంబూలాలలో కూడా దీనిని ఉపయోగిస్తున్నారు.
 
'''Tobacco''' is an [[agricultural]] product, recognized as an addictive drug, processed from the fresh [[leaves]] of plants in the genus ''[[Nicotiana]]''. Tobacco has long been in use as an [[entheogen]] in the Americas. However, upon the arrival of [[Europeans]] in North America, it quickly became popularized as a trade item and as a recreational drug. This popularization led to the development of the southern economy of the [[United States]] until it gave way to cotton. Following the [[American Civil War]], a change in demand and a change in labor force allowed for the development of the [[cigarette]]. This new product quickly led to the growth of tobacco companies until the scientific controversy of the mid-1900s.
 
There are many species of tobacco, which are all encompassed by the plant genus ''Nicotiana''. The word ''nicotiana'' (as well as ''[[nicotine]]'') was named in honor of [[Jean Nicot]], French ambassador to Portugal, who in 1559 sent it as a medicine to the court of [[Catherine de Medici]].<ref>[http://www.tc.columbia.edu/centers/cifas/drugsandsociety/background/chronologydruguse.html Heading: 1550–1575 Tobacco, Europe.]</ref> The effects of tobacco on human health are significant, and vary depending on the method by which it used and the amount consumed. Of the various methods of consumption the primary [[Health effects of tobacco|health risks]] pertain to diseases of the [[cardiovascular system]] by the vector of smoking, which over time allows high quantities of [[carcinogen]]s to deposit in the mouth, throat, and lungs.<!-- WHEN THE BENEFITS SECTION BECOME BETTER DEVELOPED, ADD IT HERE -->
 
Because of the addictive properties of nicotine, [[Physiological tolerance|tolerance]] and [[Chemical dependency|dependence]] develop. Absorption quantity, frequency, and speed of tobacco consumption are believed to be directly related to biological strength of nicotine dependence, [[addiction]], and tolerance.<ref>{{cite web|url=http://www.tobaccofacts.org/tob_truth/soaddictive.html |title=Tobacco Facts - Why is Tobacco So Addictive? |publisher=Tobaccofacts.org |date= |accessdate=2008-09-18}}</ref><ref>{{cite web|url=http://www.stanford.edu/group/SICD/PhilipMorris/pmorris.html |title=Philip Morris Information Sheet |publisher=Stanford.edu |date= |accessdate=2008-09-18}}</ref> The usage of tobacco, is an activity that is practiced by some 1.1&nbsp;billion people, and up to 1/3 of the adult population.<ref name="Gilman26">Saner L.

Tobacco is cultivated similar to other agricultural products. [[Seed]]s are sown in [[cold frame]]s or hotbeds to prevent attacks from insects, and then transplanted into the fields. Tobacco is an annual crop, which is usually harvested in a large single-piece farm equipment.
 
After harvest, tobacco is stored to allow for curing, which allow for the slow [[oxidation]] and degradation of [[carotenoid]]s. This allows for the agricultural product to take on properties that are usually attributed to the "smoothness" of the smoke. Following this, tobacco is packed into its various forms of consumption which include smoking, chewing, sniffing, and so on.<!-- ADD ANOTHER PARAGRAPH WHEN THE CULTURAL IMPACT SECTION BECOMES MORE COMPLETE -->
