'''Tobacco''' is the common name of several plants in the [[genus]] ''[[Nicotiana]]'' of the [[Family (biology)|family]] [[Solanaceae]], and the general term for any product prepared from the [[curing of tobacco|cured]] [[leaves]] of these plants. [[Nicotiana#Species|More than 70 species]] of tobacco are known, but the chief commercial crop is [[Nicotiana tabacum|''N. tabacum'']]. The more potent variant [[Nicotiana rustica|''N. rustica'']] is also used in some countries.

Dried tobacco  leaves are mainly used for [[Tobacco smoking|smoking]] in [[cigarette]]s and [[cigar]]s, as well as [[pipe smoking|pipes]] and [[Mu'assel|shishas]]. They can also be consumed as [[Snuff (tobacco)|snuff]], [[chewing tobacco]], [[dipping tobacco]], and [[snus]].

Tobacco contains the highly addictive [[stimulant]] [[alkaloid]] [[nicotine]] as well as [[harmala alkaloid]]s.<ref>{{Cite encyclopedia |title=Tobacco |encyclopedia=The Encyclopaedia of Psychoactive Substances |publisher=[[Little, Brown and Company]] |last1=Rudgley |first1=Richard |author-link=Richard Rudgley |location=London |url=https://www.biopsychiatry.com/tobacco/ |access-date=November 26, 2017 |date=1998  |isbn=9780316643474 |oclc=39129000 |archive-url=https://web.archive.org/web/20220927041956/https://www.biopsychiatry.com/tobacco/ |archive-date=27 September 2022 }}</ref> Tobacco use is a cause or risk factor for many deadly diseases, especially those affecting the [[heart]], [[liver]], and [[lung]]s, as well as [[Health effects of tobacco#Cancer|many cancers]].

The English word ''tobacco'' originates from the Spanish word "tabaco".<ref name="Ernst">{{Cite journal |last=Ernst |first=A. |date=1889 |title=On the etymology of the word tobacco |url=https://zenodo.org/record/1448956 |journal=[[American Anthropologist]] |volume=A2 |issue=2 |pages=133–142 |doi=10.1525/aa.1889.2.2.02a00020 |doi-access=free}}</ref> The precise origin of this word is disputed, but it is generally thought to have derived, at least in part, from [[Taíno language|Taíno]], the [[Arawakan]] language of the [[Caribbean]]. In Taíno, it was said to mean either a roll of tobacco leaves (according to [[Bartolomé de las Casas]], 1552), or to ''tabago'', a kind of L-shaped pipe used for sniffing tobacco smoke (according to Oviedo, with the leaves themselves being referred to as ''cohiba'').<ref>{{Cite web |last=Hilton |first=Ronald |author-link=Ronald Hilton |title=Christopher Columbus discovers Cuba |date=3 April 2011 |url=http://wais.stanford.edu/Cuba/cuba_ColumbusDiscoversCuba(110503).html |url-status=dead |archive-url=https://web.archive.org/web/20110901214953/http://wais.stanford.edu/Cuba/cuba_ColumbusDiscoversCuba(110503).html |archive-date=1 September 2011 |series=[[World Association of International Studies]] |publisher=[[Stanford University]]}}</ref><ref name=Ernst/>

However, perhaps coincidentally, similar words in Spanish, Portuguese and Italian were used from 1410 for certain medicinal [[herb]]s. These probably derived from the Arabic {{lang|ar|طُبّاق|rtl=yes}} {{transliteration|ar|ṭubbāq}} (also {{lang|ar|طُباق|rtl=yes}} {{transliteration|ar|ṭubāq}}), a word reportedly dating to the ninth century, referring to various herbs.<ref>{{Cite encyclopedia |title=طُباق |encyclopedia=[[Arabic–English Lexicon|An Arabic-English Lexicon: Derived From the Best and the Most Copious Eastern Sources]] |publisher=[[Williams and Norgate]] |location=London |url=http://ejtaal.net/aa/ |last=Lane |first=Edward William |date=1863 |author-link=Edward William Lane |volume=I, Book 5 |page=1827 |isbn=978-0-342-25192-6 |oclc=1299308839 |archive-url=https://web.archive.org/web/20160622063627/http://ejtaal.net/aa/#hw4=h660,ll=1916,ls=5,la=2636,sg=645,ha=438,pr=97,vi=240,mgf=549,mr=381,mn=839,aan=360,kz=1457,ulq=1133,uqa=265,uqw=990,umr=652,ums=546,umj=489,uqq=210,bdw=549,amr=392,asb=593,auh=947,dhq=338,mht=549,msb=147,tla=68,amj=481,ens=1,mis=1311 |archive-date=June 22, 2016 |issue=5 |access-date=June 21, 2016 |url-status=bot: unknown }}</ref><ref>The word {{transliteration|ar|ṭubāq}} no longer refers to various herbs, but has come to refer, in some dialects, specifically to tobacco.

Following the arrival of the Europeans to the Americas, tobacco became increasingly popular as a trade item. [[Hernández de Boncalo]], Spanish chronicler of the Indies, was the first European to bring tobacco seeds to the [[Old World]] in 1559 following orders of King [[Philip II of Spain]]. These seeds were planted in the outskirts of [[Toledo, Spain|Toledo]], more specifically in an area known as "Los Cigarrales" named after the continuous plagues of cicadas (''cigarras'' in Spanish). Before the development of the lighter Virginia and white burley strains of tobacco, the smoke was too harsh to be inhaled. Small quantities were smoked at a time, using a pipe like the ''[[midwakh]]'' or ''[[kiseru]],'' or newly invented waterpipes such as the [[bong]] or the [[hookah]] (see [[Nicotiana rustica#Thuốc lào|thuốc lào]] for a modern continuance of this practice). Tobacco became so popular that the English colony of Jamestown used it as currency and began exporting it as a cash crop; tobacco is often credited as being the export that saved Virginia from ruin.<ref>{{Cite book|title=The Relentless Revolution: A History of Capitalism|last=Appleby|first=Joyce|publisher=W.W. Norton & Company|year=2010|pages=131}}</ref>

The alleged benefits of tobacco also contributed to its success. The astronomer [[Thomas Harriot]], who accompanied [[Sir Richard Grenville]] on his 1585 expedition to [[Roanoke Island]], thought that the plant "openeth all the pores and passages of the body" so that the bodies of the natives "are notably preserved in health, and know not many grievous diseases, wherewithal we in England are often times afflicted."<ref>{{Cite report |url=https://www.gutenberg.org/files/4247/4247-h/4247-h.htm |title=A BRIEFE AND TRUE REPORT OF THE NEW FOUND LAND OF VIRGINIA |last=Hariot |first=Thomas |date=1590 |publisher=[[Project Gutenberg]]}}</ref>

Production of tobacco for smoking, chewing, and snuffing became a major industry in Europe and its colonies by 1700.<ref>Eric Burns, ''The Smoke of the Gods: A Social History of Tobacco'' (2006), A popular history focused on the US.</ref><ref>Jordan Goodman, ''Tobacco in History: The Cultures of Dependence'' (1993), A scholarly history worldwide.</ref>

In the late 19th century, cigarettes became popular. [[James Bonsack]] invented a machine to automate cigarette production. This increase in production allowed tremendous growth in the [[tobacco industry]] until the health revelations of the late 20th century.<ref>Richard Kluger, ''Ashes to Ashes: America's Hundred-Year Cigarette War'' (1996)</ref><ref>Allan Brandt, ''The Cigarette Century: The Rise, Fall, and Deadly Persistence of the Product That Defined America'' (2007)</ref>

Following the scientific revelations of the mid-20th century, tobacco was condemned as a health hazard, and eventually became recognized as a cause of cancer, as well as other respiratory and circulatory diseases. In the United States, this led to the [[Tobacco Master Settlement Agreement]], which settled the many lawsuits by the U.S. states in exchange for a combination of yearly payments to the states and voluntary restrictions on advertising and marketing of tobacco products.{{citation needed|date=January 2021}}

In the 1970s, [[Brown & Williamson]] cross-bred a strain of tobacco to produce [[Y1 (tobacco)|Y1]], a strain containing an unusually high nicotine content, nearly doubling from 3.2 to 3.5%, to 6.5%. In the 1990s, this prompted the [[Food and Drug Administration]] to allege that [[tobacco industry|tobacco companies]] were intentionally manipulating the nicotine content of [[cigarette]]s.{{citation needed|date=January 2021}}

The desire of many addicted smokers to quit has led to the development of [[nicotine replacement therapy|tobacco cessation products]].<ref>{{Cite journal|last=Commissioner|first=Office of the|date=2020-09-09|title=Want to Quit Smoking?

[[File:Native American tobacco flower.jpg|thumb|upright|Tobacco (''[[Nicotiana rustica]]'') flower, leaves, and buds]]
Many species of tobacco are in the genus of herbs ''Nicotiana''. It is part of the nightshade [[family (biology)|family]] ([[Solanaceae]]) indigenous to North and South America, Australia, south west Africa, and the [[Oceania|South Pacific]].<ref name="Lewis">{{cite journal|last1=Lewis|first1=Albert|title=Tobacco in New Guinea|journal=The American Anthropologist|date=1931|volume=33|issue=1|pages=134–139|doi=10.1525/aa.1931.33.1.02a00290|doi-access=free}}</ref>

Most nightshades contain varying amounts of [[nicotine]], a powerful [[neurotoxin]] to [[insect]]s. However, tobaccos tend to contain a much higher concentration of nicotine than the others. Unlike many other Solanaceae species, they do not contain [[tropane alkaloid]]s, which are often poisonous to humans and other animals.

Despite containing enough nicotine and other compounds such as [[germacrene]] and [[anabasine]] and other [[piperidine]] alkaloids (varying between species) to deter most [[herbivore]]s,<ref>{{Cite journal |last1=Panter |first1=KE |last2=Keeler |first2=RF |last3=Bunch |first3=TD |last4=Callan |first4=RJ |year=1990 |title=Congenital skeletal malformations and cleft palate induced in goats by ingestion of Lupinus, Conium and Nicotiana species  |journal=Toxicon |pages=1377–1385 |volume=28 |issue=12 |pmid=2089736|doi=10.1016/0041-0101(90)90154-Y }}</ref> a number of such animals have [[evolution|evolve]]d the ability to feed on ''Nicotiana'' species without being harmed. Nonetheless, tobacco is unpalatable to many species due to its other attributes.

===Types===
{{Main|Types of tobacco}}

The types of tobacco include:
* [[Types of tobacco#Aromatic Fire-cured|Aromatic fire-cured]] is cured by smoke from open fires. In the United States, it is grown in northern middle Tennessee, central Kentucky, and [[Virginia]]. Fire-cured tobacco grown in [[Kentucky]] and [[Tennessee]] is used in some chewing tobaccos, moist snuff, some cigarettes, and as a condiment in pipe tobacco blends. Another fire-cured tobacco is [[Latakia (tobacco)|Latakia]], which is produced from oriental varieties of ''N. tabacum''. The leaves are cured and smoked over smoldering fires of local hardwoods and aromatic shrubs in [[Cyprus]] and [[Syria]].
* [[Types of tobacco#Brightleaf tobacco|Brightleaf tobacco]] is commonly known as "Virginia tobacco", often regardless of the state where it is planted. Prior to the [[American Civil War]], most tobacco grown in the US was fire-cured dark-leaf. Sometime after the [[War of 1812]], demand for a milder, lighter, more aromatic tobacco arose. [[Ohio]], [[Pennsylvania]] and [[Maryland]] all innovated with milder varieties of the tobacco plant. Farmers discovered that bright leaf tobacco needs thin, starved soil, and those who could not grow other crops found that they could grow tobacco. Confederate soldiers traded it with each other and Union soldiers, and developed quite a taste for it. At the end of the war, the soldiers went home and a national market had developed for the local crop.
* [[Types of tobacco#Broadleaf|Broadleaf]], a dark tobacco varietal family popular for producing enormous, resilient, and thick wrapper leaves.<ref>[https://tobacconistuniversity.org/glossary.php], Broadleaf tobacco, Tobacco University</ref>
* [[Burley (tobacco)|Burley tobacco]] is an air-cured tobacco used primarily for [[cigarette]] production. In the U.S., burley tobacco plants are started from pelletized seeds placed in polystyrene trays floated on a bed of fertilized water in March or April.
* [[Cavendish tobacco|Cavendish]] is more a process of curing and a method of cutting tobacco than a type. The processing and the cut are used to bring out the natural sweet taste in the tobacco. Cavendish can be produced from any tobacco type, but is usually one of, or a blend of Kentucky, Virginia, and burley, and is most commonly used for pipe tobacco and cigars.
* [[Criollo tobacco]] is primarily used in the making of [[cigar]]s. It was, by most accounts, one of the original Cuban tobaccos that emerged around the time of [[Christopher Columbus|Columbus]].
* [[Dokha]] is a tobacco originally grown in [[Iran]], mixed with leaves, bark, and herbs for smoking in a ''[[midwakh]]''.
* [[Turkish tobacco]] is a sun-cured, highly aromatic, small-leafed variety (''[[Nicotiana tabacum]]'') grown in Turkey, Greece, [[Bulgaria]], and [[North Macedonia]]. Originally grown in regions historically part of the [[Ottoman Empire]], it is also known as "oriental". Many of the early brands of cigarettes were made mostly or entirely of Turkish tobacco; today, its main use is in blends of pipe and especially cigarette tobacco (a typical American cigarette is a blend of bright Virginia, burley, and Turkish).
* [[Perique]] was developed in 1824 through the technique of pressure-fermentation of local tobacco by a farmer, Pierre Chenet. Considered the [[truffle]] of [[smoking pipe (tobacco)|pipe]] tobaccos, it is used as a component in many blended pipe tobaccos, but is too strong to be smoked pure. At one time, the freshly moist Perique was also chewed, but none is now sold for this purpose. It is typically blended with pure Virginia to lend spice, strength, and coolness to the blend.
* [[Types of tobacco#Shade tobacco|Shade tobacco]] is cultivated in [[Connecticut]] and [[Massachusetts]]. Early Connecticut [[colonist]]s acquired from the Native Americans the habit of smoking tobacco in pipes, and began cultivating the plant commercially, though the [[Puritans]] referred to it as the "evil weed". The [[Connecticut shade tobacco|Connecticut shade]] industry has weathered some major [[Disaster|catastrophes]], including a devastating [[hail]]storm in 1929, and an epidemic of brown spot fungus in 2000, but is now in danger of disappearing altogether, given the increase in the value of land.
* [[Types of tobacco#White Burley|White burley]] air-cured leaf was found to be more mild than other types of tobacco. In 1865, George Webb of [[Brown County, Ohio]] planted red [[Burley (tobacco)|burley]] seeds he had purchased, and found a few of the seedlings had a whitish, sickly look, which became white burley.
* [[Types of tobacco#Wild Tobacco|Wild tobacco]] is native to the southwestern United States, Mexico, and parts of South America. Its botanical name is ''Nicotiana rustica''.

Tobacco is cultivated similarly to other agricultural products. [[Seed]]s were at first quickly scattered onto the soil. However, young plants came under increasing attack from [[flea beetle]]s (''Epitrix cucumeris'' or ''E. pubescens''), which caused destruction of half the tobacco crops in United States in 1876. By 1890, successful experiments were conducted that placed the plant in a frame covered by thin cotton fabric. Today, tobacco seeds are sown in [[cold frame]]s or hotbeds, as their [[germination]] is activated by light.<ref>{{cite journal |last1=Garner |first1=W.

After the plants are about {{convert| 8| inch|cm}}  tall, they are transplanted into the fields. Farmers used to have to wait for rainy weather to plant. A hole is created in the tilled earth with a tobacco peg, either a curved wooden tool or deer antler. After making two holes to the right and left, the planter would move forward two feet, select plants from his/her bag, and repeat. Various mechanical tobacco planters like Bemis, New Idea Setter, and New Holland [[Transplanter]] were invented in the late 19th and 20th centuries to automate the process: making the hole, watering it, guiding the plant in — all in one motion.<ref>{{cite book|last1=van Willigen|first1=John|last2=Eastwood|first2=Susan|title=Tobacco Culture: Farming Kentucky's Burley Belt|date=2015|publisher=University Press of Kentucky|isbn=9780813148083|page=91|url=https://books.google.com/books?id=JIkfBgAAQBAJ|access-date=February 2, 2018}}</ref>

Tobacco is cultivated annually, and can be [[harvest]]ed in several ways. In the oldest method, still used today, the entire plant is harvested at once by cutting off the stalk at the ground with a tobacco knife; it is then speared onto sticks, four to six plants a stick, and hung in a curing barn. In the 19th century, bright tobacco began to be harvested by pulling individual leaves off the stalk as they ripened. The leaves ripen from the ground upwards, so a field of tobacco harvested in this manner entails the serial harvest of a number of "primings", beginning with the ''volado'' leaves near the ground, working to the ''seco'' leaves in the middle of the plant, and finishing with the potent ''[[ligero]]'' leaves at the top. Before harvesting, the crop must be ''topped'' when the pink flowers develop. Topping always refers to the removal of the tobacco flower before the leaves are systematically harvested. As the industrial revolution took hold, the harvesting wagons which were used to transport leaves were equipped with man-powered stringers, an apparatus that used twine to attach leaves to a pole. In modern times, large fields are harvested mechanically, although topping the flower and in some cases the plucking of immature leaves is still done by hand.

In the U.S., [[North Carolina]] and [[Kentucky]] are the leaders in tobacco production, followed by [[Tennessee]], [[Virginia]], [[Georgia (U.S. state)|Georgia]], [[South Carolina]] and [[Pennsylvania]].<ref>{{Cite web|url=https://quickstats.nass.usda.gov/|title=USDA/NASS QuickStats Ad-hoc Query Tool|website=quickstats.nass.usda.gov|date=2019|access-date=July 1, 2020}}</ref>

===Curing===
{{Main|Curing of tobacco}}
[[File:Tobacco barn.JPG|thumb|Tobacco barn in [[Simsbury, Connecticut]] used for air curing of shade tobacco]]
[[File:Tobacco drying iran.jpg|thumb|Sun-cured tobacco, [[Bastam, West Azerbaijan|Bastam]], [[Iran]]]]

Curing and subsequent aging allow for the slow [[oxidation]] and degradation of [[carotenoid]]s in tobacco leaf. This produces certain compounds in the tobacco leaves and gives a sweet hay, [[tea]], [[rose oil]], or fruity aromatic flavor that contributes to the "smoothness" of the smoke. Starch is converted to sugar, which [[glycation|glycates]] protein, and is oxidized into [[advanced glycation endproduct]]s (AGEs), a [[caramelization]] process that also adds flavor. Inhalation of these AGEs in tobacco smoke contributes to [[atherosclerosis]] and [[cancer]].<ref>{{cite journal|vauthors=Cerami C, Founds H, Nicholl I, Mitsuhashi T, Giordano D, Vanpatten S, Lee A, Al-Abed Y, Vlassara H, Bucala R, Cerami A |title=Tobacco smoke is a source of toxic reactive glycation products|journal=Proceedings of the National Academy of Sciences of the United States of America|volume=94|issue=25|year=1997|pages=13915–20|doi=10.1073/pnas.94.25.13915|pmid=9391127|pmc=28407|bibcode=1997PNAS...9413915C|doi-access=free}}</ref> Levels of AGEs are dependent on the curing method used.

Tobacco can be cured through several methods, including:

* '''[[Curing of tobacco#Air|Air-cured]]''' tobacco is hung in well-ventilated barns and allowed to dry over a period of four to eight weeks. Air-cured tobacco is low in sugar, which gives the tobacco smoke a light, mild flavor, and high in nicotine. Cigar and burley tobaccos are 'dark' air-cured.<ref>"tobacco curing." The Hutchinson Unabridged Encyclopedia with Atlas and Weather guide. Abington: Helicon, 2010. Credo Reference. Web. September 26, 2012.</ref>
* '''[[Curing of tobacco#Fire|Fire-cured]]''' tobacco is hung in large barns where fires of hardwoods are kept on continuous or intermittent low smoulder, and takes between three days and ten weeks, depending on the process and the tobacco. Fire curing produces a tobacco low in sugar and high in nicotine. Pipe tobacco, chewing tobacco, and snuff are fire-cured.
* '''[[Curing of tobacco#Flue|Flue-cured]]''' tobacco was originally strung onto tobacco sticks, which were hung from tier poles in curing barns (Aus: [[kiln]]s, also traditionally called 'oasts'). These barns have flues run from externally fed fire boxes, heat-curing the tobacco without exposing it to smoke, slowly raising the temperature over the course of the curing. The process generally takes about a week. This method produces cigarette tobacco that is high in sugar and has medium to high levels of nicotine. Most cigarettes incorporate flue-cured tobacco, which produces a milder, more inhalable smoke. It is estimated that 1 tree is cut to flue-cure every 300 cigarettes, resulting in serious environmental consequences.<ref name="who env impact"/>
* '''[[Curing of tobacco#Sun|Sun-cured]]''' tobacco dries uncovered in the sun. This method is used in Turkey, Greece, and other Mediterranean countries to produce oriental tobacco. Sun-cured tobacco is low in sugar and nicotine and is used in cigarettes.

Some tobaccos go through a second stage of curing, known as ''[[Fermentation (food)|fermenting]]'' or ''sweating''.<ref>{{cite web|title=Tobacco Leaf Harvesting, Curing, and Fermenting|url=https://www.leafonly.com/tobacco-harvesting-curing-fermenting.php|website=Leaf Only|access-date=April 20, 2017}}</ref> [[Cavendish Tobacco|Cavendish]] undergoes fermentation pressed in a ''casing'' solution containing sugar and/or flavoring.<ref>{{cite web|title=Pipe Tobacco|url=http://www.tobacconistuniversity.org/tobacco-college/pipe-special-types2.asp |access-date=April 20, 2017 |url-status=dead |archive-url=https://web.archive.org/web/20131017001708/http://www.tobacconistuniversity.org/tobacco-college/pipe-special-types2.asp |archive-date=October 17, 2013 }}</ref>

====Trends====
[[File:Preparando o tabaco em Balibó.jpg|thumb|Tobacco production in [[Portuguese Timor]] in the 1930s]]

China's share of the world market increased from 17% in 1971 to 47% in 1997.<ref name="United Nations 2010"/> This growth can be partially explained by the existence of a low import tariff on foreign tobacco entering China.

Every year, about 5.9 million tons of tobacco are produced throughout the world. The top producers of tobacco are China (36.3%), India (12.9%), Brazil (11.9%) and Zimbabwe (3.5%).<ref name="FAOSTAT"/>

=====China=====
Around the peak of global tobacco production, 20 million rural Chinese households were producing tobacco on 2.1 million hectares of land.<ref name="issues in global economy"/> While it is the major crop for millions of Chinese farmers, growing tobacco is not as profitable as cotton or sugarcane, because the Chinese government sets the market price. While this price is guaranteed, it is lower than the natural market price, because of the lack of market risk. To further control tobacco in their borders, China founded a [[State Tobacco Monopoly Administration]] (STMA) in 1982. The STMA controls tobacco production, marketing, imports, and exports, and contributes 12% to the nation's national income.<ref>{{cite web |url=http://www.gov.cn/english/2005-10/03/content_74295.htm |title=People's Republic of China.

====Economy====
[[File:MRO Cuba Harvest 01.jpg|thumb|Tobacco harvesting, [[Viñales Valley]], Cuba]]
Major tobacco companies have encouraged global tobacco production.

Tobacco production requires the use of large amounts of [[pesticide]]s. Tobacco companies recommend up to 16 separate applications of pesticides just in the period between planting the seeds in greenhouses and transplanting the young plants to the field.<ref name="Taylor, Peter 1994">{{cite book|last=Taylor|first=Peter|title=Smoke Ring: The Politics of Tobacco|publisher=Panos Briefing Paper|location=London|date=September 1994}}</ref> Pesticide use has been worsened by the desire to produce larger crops in less time because of the decreasing market value of tobacco. Pesticides often harm tobacco farmers because they are unaware of the health effects and the proper safety protocol for working with pesticides. These pesticides, as well as fertilizers, end up in the soil, waterways, and the food chain.<ref>{{cite book|title=FAO Yearbook, Production, Volume 48|year=1995}}</ref> Coupled with child labor, pesticides pose an even greater threat.

Furthermore, the wood used to cure tobacco in some places leads to deforestation. While some big tobacco producers such as China and the United States have access to petroleum, coal, and natural gas, which can be used as alternatives to wood, most developing countries still rely on wood in the curing process.<ref name="wwf.panda"/> Brazil alone uses the wood of 60 million trees per year for curing, packaging, and rolling cigarettes.<ref name="Taylor, Peter 1994"/>

===Genetic modification===
Because of its importance as a research tool, transgenic tobacco was the first genetically modified (GM) crop to be tested in field trials, in the United States and France in 1986; China became the first country in the world to approve commercial planting of a GM crop in 1993, which was tobacco.<ref name="James 1996">{{cite web|last=James|first=Clive|title=Global Review of the Field Testing and Commercialization of Transgenic Plants: 1986 to 1995|url=http://www.isaaa.org/kc/Publications/pdfs/isaaabriefs/Briefs%201.pdf|publisher=The International Service for the Acquisition of Agri-biotech Applications|access-date=July 17, 2010|year=1996}}</ref>

====Field trials====
Many varieties of transgenic tobacco have been intensively tested in field trials. Agronomic traits such as resistance to pathogens (viruses, particularly to the [[tobacco mosaic virus]] (TMV); fungi; bacteria and nematodes); weed management via herbicide tolerance; resistance against insect pests; resistance to drought and cold; and production of useful products such as pharmaceuticals; and use of GM plants for [[bioremediation]], have all been tested in over 400 field trials using tobacco.<ref name=GMOCompass>{{cite web |url=http://www.gmo-compass.org/eng/database/plants/304.tobacco.html |title=Tobacco |publisher=GMO Compass |access-date=October 3, 2013 |url-status=dead |archive-url=https://web.archive.org/web/20131002090217/http://www.gmo-compass.org/eng/database/plants/304.tobacco.html |archive-date=October 2, 2013}}</ref>

==Consumption==
{{Further|Tobacco products}}
{{More citations needed section|date=January 2021}}
Tobacco is consumed in many forms and through a number of different methods. Some examples are:

* '''[[Beedi]]''' (also known as bidis or biris) are thin, often flavoured cigarettes from India made of tobacco wrapped in a [[Diospyros melanoxylon|tendu]] leaf, and secured with coloured thread at one end.<ref>{{Cite web|last=Tobacco Free Kids|date=2008|title=Bidis: An Overview|url=https://www.tobaccofreekids.org/assets/global/pdfs/en/IW_facts_products_bidis_overview.pdf|access-date=October 27, 2021|website=Tobacco Free Kids}}</ref> 
* '''[[Chewing tobacco]]''' is the oldest way of consuming tobacco leaves. It is consumed orally, in two forms: through sweetened strands ("chew" or "chaw"), or in a shredded form ("dip"). When consuming the long, sweetened strands, the tobacco is lightly chewed and compacted into a ball. When consuming the shredded tobacco, small amounts are placed at the bottom lip, between the gum and the teeth, where it is gently compacted, thus it can often be called dipping tobacco. Both methods stimulate the salivary glands, which led to the development of the [[spittoon]].
* '''[[Cigar]]s''' are tightly rolled bundles of dried and fermented tobacco, which are ignited so their smoke may be drawn into the smokers' mouths.
* '''[[Cigarette]]s''' are a product consumed through inhalation of smoke and manufactured from cured and finely cut tobacco leaves and reconstituted tobacco, often combined with other additives, then rolled into a paper cylinder.
* '''[[Creamy snuff]]''' is tobacco paste, consisting of tobacco, clove oil, glycerin, spearmint, menthol, and camphor, and sold in a toothpaste tube. It is marketed mainly to women in India, and is known by the brand names Ipco (made by Asha Industries), Denobac, Tona, and Ganesh. It is locally known as ''mishri'' in some parts of Maharashtra.
* '''[[Dipping tobacco]]s''' are a form of [[smokeless tobacco]]. Dip is occasionally referred to as "chew", and because of this, it is commonly confused with [[chewing tobacco]], which encompasses a wider range of products. A small clump of dip is 'pinched' out of the tin and placed between the lower or upper lip and gums. Some brands, as with snus, are portioned in small, porous pouches for less mess.
* '''[[Gutka]]''' is a preparation of crushed betel nut, tobacco, and sweet or savory flavorings. It is manufactured in India and exported to a few other countries. A mild stimulant, it is sold across India in small, individual-sized packets.
* '''[[Heat-not-burn product]]s''' heat rather than burn tobacco to generate an aerosol that contains nicotine.
* '''[[Dokha]]''' is a middle eastern tobacco with high nicotine levels grown in parts of Oman and Hatta, which is smoked through a thin pipe called a medwakh. It is a form of tobacco which is dried up and ground and contains little to no additives excluding spices, fruits, or flowers to enhance smell and flavor.
* '''[[Hookah]]''' is a single- or multistemmed (often glass-based) water pipe for smoking. Hookahs were first used in India and Persia;<ref>American Lung Association. February 2007 [http://www.lungusa2.org/embargo/slati/Trendalert_Waterpipes.pdf An Emerging Deadly Trend: Waterpipe Tobacco Use] {{Webarchive|url=https://web.archive.org/web/20140102171735/http://www.lungusa2.org/embargo/slati/Trendalert_Waterpipes.pdf |date=January 2, 2014 }}</ref> the hookah has gained immense popularity, especially in the Middle East. A hookah operates by water filtration and indirect heat. It can be used for smoking herbal fruits or [[moassel]], a mixture of tobacco, flavouring, and [[honey]] or [[glycerin]].
* '''[[Kreteks]]''' are cigarettes made with a complex blend of tobacco, cloves, and a flavoring "sauce". They were first introduced in the 1880s in Kudus, Java, to deliver the medicinal [[eugenol]] of cloves to the lungs.
* '''[[Roll-your-own]]''', often called 'rollies' or 'roll-ups', are relatively popular in some European countries. These are prepared from loose tobacco, cigarette papers, and filters all bought separately. They are usually cheaper to make.
* '''[[Snuff (tobacco)|Snuff]]''' is a ground smokeless tobacco product, inhaled or "snuffed" through the nose. If referring specifically to the orally consumed moist snuff, see [[dipping tobacco]].
* '''[[Snus]]''' is a steam-pasteurized moist powdered tobacco product that is not fermented, and induces minimal salivation. It is consumed by placing it (loose or in little pouches) against the upper gums for an extended period of time. It is somewhat similar to dipping tobacco but does not require spitting and is significantly lower in [[Tobacco-specific nitrosamines|TSNA]]s.
* '''Tobacco edibles''', often in the form of an infusion or a spice, have gained popularity in recent years.
* '''[[Tobacco pipe]]s''' typically consist of a small chamber (the bowl) for the combustion of the tobacco to be smoked and a thin stem (shank) that ends in a mouthpiece (the bit). Shredded pieces of tobacco are placed in the chamber and ignited.
* '''[[Tobacco smoke enema]]s''' were employed by the [[indigenous peoples of the Americas#North America|indigenous peoples of North America]] to stimulate respiration, injecting the smoke with a rectal tube.<ref>{{Citation |last1 = Hurt |first1 = Raymond |last2 = Barry |first2 = J.

==Impact==

===Social===
Smoking in public was, for a long time, reserved for men, and when done by women was sometimes associated with [[promiscuity]]; in Japan, during the [[Edo period]], prostitutes and their clients often approached one another under the guise of offering a smoke. The same was true in 19th-century Europe.{{sfn|Gilman|Zhou|2004|p=[https://books.google.com/books?id=mM5bYb_uVcwC&pg=PA92 92–99]}}

Following the [[American Civil War]], the use of tobacco, primarily in cigars, became associated with [[masculinity]] and power.

====Islam====
{{Main|Islamic views on tobacco}}
Most Islamic scholars have condemned tobacco due to its harmful effects on health. The earliest [[fatwa]] (religious opinion) against tobacco use dates from 1602, and today, most major Islamic sects prohibit muslims from using it. While tobacco is not mentioned in the Quran, the Quran does instruct muslims to live healthy lives.

====Sikhism====
{{Further|Prohibitions in Sikhism}}
[[Sikhism]], a monotheistic religion from India, considers tobacco consumption as a taboo and very bad for health and spirituality.

Tobacco smoking harms health because of the toxic chemicals in tobacco smoke, including [[carbon monoxide]], [[cyanide]], and [[carcinogens]], which have been proven to cause heart and lung diseases and cancer.
Thousands of different substances in cigarette smoke, including [[polycyclic aromatic hydrocarbons]] (such as [[benzopyrene]]), [[formaldehyde]], [[cadmium]], [[nickel]], [[arsenic]], [[tobacco-specific nitrosamines]], and [[phenols]] contribute to the harmful effects of smoking.<ref name="tobaccocontrol.bmj.com">{{cite journal|author=Proctor Robert N|year=2012|title=The history of the discovery of the cigarette-lung cancer link: evidentiary traditions, corporate denial, global toll|url=http://tobaccocontrol.bmj.com/content/21/2/87.full.pdf|journal=Tobacco Control|volume=21|issue=2|pages=87–91|doi=10.1136/tobaccocontrol-2011-050338|pmid=22345227|s2cid=2734836|doi-access=free}}</ref>

The harms caused by inhaling tobacco smoke include diseases of the [[heart]] and [[lung]]s, with smoking being a major risk factor for [[myocardial infarction|heart attacks]], [[stroke]]s, [[chronic obstructive pulmonary disease]] (emphysema), and [[cancer]] (particularly cancers of the [[Lung cancer|lungs]], [[Cancer of the larynx|larynx, mouth]], and [[pancreatic cancers|pancreas]]). Cancer is caused by inhaling carcinogenic substances in tobacco smoke.

Inhaling secondhand tobacco smoke (which has been exhaled by a smoker) can cause lung cancer in nonsmoking adults. In the United States, about 3,000 adults die each year due to lung cancer from secondhand smoke exposure.

===Economic===
Tobacco has a significant economic impact. The global tobacco market in 2010 was estimated at US$760 billion, excluding China.<ref>{{Cite web|url=http://www.bat.com/group/sites/UK__9D9KCY.nsf/vwPagesWebLive/DO9DCKFM|title=British American Tobacco - The global market|website=www.bat.com|language=en|access-date=March 15, 2018|archive-date=March 10, 2018|archive-url=https://web.archive.org/web/20180310114510/http://www.bat.com/group/sites/UK__9D9KCY.nsf/vwPagesWebLive/DO9DCKFM|url-status=dead}}</ref>  The global revenues from tobacco taxes in 2013-2014 was approximately $269 billion.

In China, cigarette manufacturing is one of the few profitable state-owned industries. For example, in 1998 the 1 429 state-owned enterprises in Yunnan province had revenue of [[Renminbi]] (RMB) 69.1 billion (US$8.3 billion) while 8 cigarette manufacturing plants alone accounted for about 53 percent (or RMB 36.2 billion) of total provincial industry sales.<ref name="issues in global economy">{{Cite book |date=2003 |title=Issues in the global tobacco economy : selected case studies. |url=https://www.fao.org/publications/card/en/c/1391c97a-6e5f-59dc-b664-d14e5e401674/ |archive-url=https://web.archive.org/web/20220307151442/https://www.fao.org/3/y4997e/y4997e.pdf |archive-date=7 March 2022 |access-date=6 October 2022 |publisher=United Nations [[Food and Agriculture Organization]] |pages=2, 39, 43 |isbn=925105083X |oclc=55056109 |id=Series number 1810-0783}}</ref> The Chinese government also collects tax on tobacco products.

In the US, the decline in the number of smokers, the end of the [[Tobacco Transition Payment Program]] in 2014, and competition from growers in other countries, made tobacco farming economics more challenging.<ref>{{cite news|last1=Bomey|first1=Nathan|title=Thousands of farmers stopped growing tobacco after deregulation payouts|url=https://www.usatoday.com/story/money/2015/09/02/thousands-farmers-stopped-growing-tobacco-after-deregulation-payouts/32115163/|work=USA Today|date=September 2, 2015|language=en}}</ref>

Of the 1.22 billion smokers worldwide, 1 billion of them live in developing or transitional economies, and much of the disease burden and premature mortality attributable to tobacco use disproportionately affect the poor.<ref name="WHOTobaccoFactSheet" /> While smoking prevalence has declined in many developed countries, it remains high in others, and is increasing among women and in developing countries. Between one-fifth and two-thirds of men in most populations smoke.

Tobacco users must also spend a significant amount of money on cigarettes to maintain regular use, as tobacco products are often heavily taxed by governments. For example, a pack a day smoker in the state of New York would have to spend around  $4,690.25 a year on cigarettes alone.<ref>{{Cite web |title=Cost of Smoking |url=https://tobaccofreelife.org/why-quit-smoking/cost-smoking/ |access-date=2022-07-06 |website=Tobacco-Free Life |language=en-US}}</ref>

In Indonesia, the lowest income group spends 15% of its total expenditures on tobacco. In Egypt, more than 10% of low-income household expenditure is on tobacco. The poorest 20% of households in Mexico spend 11% of their income on tobacco.<ref name="who 2008 mpower"/>

===Advertising===
{{Main|Nicotine marketing}}
The tobacco industry advertises its products through a variety of media, including sponsorship, particularly of sporting events. Because of the health risks of these products, this is now one of the most highly regulated forms of marketing. Some or all forms of tobacco advertising are banned in many countries.<ref>{{Cite web |last=Products |first=Center for Tobacco |date=2022-01-28 |title=Advertising and Promotion |url=https://www.fda.gov/tobacco-products/products-guidance-regulations/advertising-and-promotion |access-date=2022-07-06 |website=FDA |language=en}}</ref>

=== Environment ===
Tobacco does a great deal to pollute the environment. Cigarette bumps or packages can easily end up in seas or lakes. Tobacco, by leading to disease, then leads to environmental pollution. It can drive up medication use. The medication industry in turn contributes to pollution, by the production process, by the disposal of medication, by packaging, etc.{{Citation needed|date=October 2022}}
