    Tobacco is an agricultural product processed from the leaves of plants in the genusNicotiana. It can be consumed, used as an organic pesticide and, in the form of nicotinetartrate, it is used in some medicines.[1] It is most commonly used as arecreational drug,and is a valuablecash crop for countries such as Cuba, China and United States.

    In consumption it most commonly appears in the forms ofsmoking,chewing, snuffing, or

    dipping tobacco, orsnus. Tobacco has long been in use as anentheogen in the Americas.However, upon the arrival ofEuropeans in North America, it quickly became popularizedas a trade item and as a recreational drug. This popularization led to the development of thesouthern economy of the United Statesuntil it gave way to cotton. Following the AmericanCivil War, a change in demand and a change in labor force allowed for the development ofthe cigarette. This new product quickly led to the growth of tobacco companies, until thescientific controversy of the mid-1900s.

    There are many species of tobacco in the plant genusNicotiana. The word nicotiana (aswell as nicotine) is in honor ofJean Nicot, French ambassador to Portugal, who in 1559sent it as a medicine to the court ofCatherine de Medici.[2]

    Because of the addictive properties ofnicotine,toleranceanddependencedevelop.Absorption quantity, frequency, and speed of tobacco consumption are believed to bedirectly related to biological strength of nicotine dependence,addiction, and tolerance.[3][4]

    The usage of tobacco is an activity that is practiced by some 1.1 billion people, and up to1/3 of the adult population.[5] The World Health Organization(WHO) reports it to be theleading preventable cause of death worldwide and estimates that it currently causes 5.4million deaths per year.[6] Rates of smoking have leveled off or declined in developedcountries, however they continue to rise indeveloping countries.

    Tobacco is cultivated similarly to other agricultural products. Seeds are sown in coldframes or hotbeds to prevent attacks from insects, and then transplanted into the fields.Tobacco is an annual crop, which is usually harvested mechanically or by hand. Afterharvest, tobacco is stored for curing, which allows for the slow oxidationand degradation

    ofcarotenoids. This allows for the agricultural product to take on properties that are usuallyattributed to the "smoothness" of the smoke. Following this, tobacco is packed into itsvarious forms of consumption, which include smoking, chewing, sniffing, and so on.

    [edit] EtymologyThe Spanish word "tabaco" is thought to have its origin in Arawakanlanguage,particularly, in theTaino language of the Caribbean. In Taino, it was said to refer either to aroll of tobacco leaves (according to Bartolome de Las Casas, 1552), or to the tabago, a kindof Y-shaped pipe for sniffing tobacco smoke (according to Oviedo; with the leavesthemselves being referred to as cohiba).[7]

    [edit] Early developments

    Tobacco had already long been used in the Americas when European settlers arrived andintroduced the practice to Europe, where it became popular. At high doses, tobacco canbecomehallucinogenic;[citation needed] accordingly, Native Americans never used the drugrecreationally. Instead, it was often consumed as anentheogen; among some tribes, this wasdone only by experienced shamans ormedicine men.[citation needed] Eastern North American

    tribes carried large amounts of tobacco in pouches as a readily accepted trade item, andoften smoked it inpipes, either in defined sacred ceremonies, or to seal a bargain,[9] andthey smoked it at such occasions in all stages of life, even in childhood.[10]It was believedthat tobacco is a gift from the Creator and that the exhaled tobacco smoke carries one'sthoughts and prayers toheaven.[11]

    An Illustration from Frederick William Fairholt's Tobacco, its History and Association,1859.

    [edit] Popularization

    Following the arrival of the Europeans, tobacco became increasingly popular as a tradeitem. It fostered the economy for the southern United States until it was replaced by cotton.Following the American civil war, a change in demand and a change in labor force allowedinventorJames Bonsackto create a machine that automated cigarette production.

    This increase in production allowed tremendous growth in the tobacco industry until thescientific revelations of the mid-1900s.

    Following the scientific revelations of the mid-1900s, tobacco became condemned as ahealth hazard, and eventually became encompassed as a cause for cancer, as well as otherrespiratory and circulatory diseases. This led to the Tobacco Master Settlement Agreement(MSA), which settled the lawsuit in exchange for a combination of yearly payments to thestates and voluntary restrictions on advertising and marketing of tobacco products.

    In the 1970s,Brown & Williamson cross-bred a strain of tobacco to produce Y1. Thisstrain of tobacco contained an unusually high amount of nicotine, nearly doubling itscontent from 3.2-3.5% to 6.5%. In the 1990s, this prompted the Food and DrugAdministration (FDA) to use this strain as evidence that tobacco companieswereintentionally manipulating the nicotine content ofcigarettes.

    In 2003, in response to growth of tobacco use in developing countries, the World HealthOrganization (WHO)[12] successfully rallied 168 countries to sign the FrameworkConvention on Tobacco Control. The Convention is designed to push for effectivelegislation and its enforcement in all countries to reduce the harmful effects of tobacco.This led to the development of tobacco cessation products.

    Tobacco flower, leaves, and budsMain article:NicotianaSee also: List of tobacco diseases

    There are many species of tobacco in the genus of herbsNicotiana. It is part of thenightshade family (Solanaceae) indigenous toNorth and South America, australia, SouthWest Africa and theSouth Pacific.

    Many plants contain nicotine, a powerful neurotoxin, that is particularly harmful to insects.However, tobaccos contain a higher concentration of nicotine than most other plants.Unlike many other Solanaceae, they do not contain tropane alkaloids, which are often

    poisonous to humans and other animals.Despite containing enough nicotine and other compounds such asgermacrene andanabasine and otherpiperidine alkaloids (varying between species) to deter mostherbivores,[13]a number of such animals have evolvedthe ability to feed onNicotianaspecies without being harmed. Nonetheless, tobacco is unpalatable to many species, andtherefore some tobacco plants (chiefly tree tobacco,N. glauca) have become established asinvasive weeds in some places.

    [edit] Types

    Main article: Types of tobacco

    There are a number of types of tobacco including, but are not limited to:

    Aromatic fire-cured, it is cured by smoke from open fires. In the United States, itis grown in northern middle Tennessee, central Kentucky and in Virginia. Fire-cured tobacco grown in Kentucky and Tennessee are used in some chewingtobaccos, moist snuff, some cigarettes, and as a condiment in pipe tobacco blends.Another fire-cured tobacco is Latakia, which is produced from oriental varieties ofN. tabacum. The leaves are cured and smoked over smoldering fires of localhardwoods and aromatic shrubs in Cyprus and Syria.

    Brightleaf tobacco, Brightleaf is commonly known as "Virginia tobacco", oftenregardless of the state where they are planted. Prior to the American Civil War,most tobacco grown in the US was fire-cured dark-leaf. This type of tobacco wasplanted in fertile lowlands, used a robust variety of leaf, and was either fire cured orair cured. Most Canadian cigarettes are made from 100% pure Virginia tobacco.[14]

    Burley tobacco, is an air-cured tobacco used primarily forcigarette production. Inthe U.S., burley tobacco plants are started from palletized seeds placed inpolystyrene trays floated on a bed of fertilized water in March or April.

    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 thetobacco. Cavendish can be produced from any tobacco type, but is usually one of, ora blend ofKentucky, Virginia, andburley, and is most commonly used for pipetobacco and cigars.

    Criollo tobacco is a type of tobacco, primarily used in the making ofcigars. It was,by most accounts, one of the original Cuban tobaccos that emerged around the timeofColumbus.

    Dokham, is a tobacco originally grown inIran, mixed with leaves, bark, and herbsfor smoking in a midwakh.

    Turkish tobacco, is a sun-cured, highly aromatic, small-leafed variety (Nicotianatabacum) that is grown in Turkey, Greece, Bulgaria, and Macedonia. Originallygrown 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 ofTurkish tobacco; today, its main use is in blends of pipe and especially cigarettetobacco (a typical American cigarette is a blend of bright Virginia, burley andTurkish).

    Perique, a farmer called Pierre Chenet is credited with first turning this local

    tobacco into the Perique in 1824 through the technique of pressure-fermentation.Considered thetruffle ofpipe tobaccos, it is used as a component in many blendedpipe tobaccos, but is too strong to be smoked pure. At one time, the freshly moistPerique was also chewed, but none is now sold for this purpose. It is typicallyblended with pure Virginia to lend spice, strength, and coolness to the blend.

    Shade tobacco, is cultivated inConnecticut and Massachusetts. Early Connecticutcolonists acquired from the Native Americans the habit of smoking tobacco inpipes, and began cultivating the plant commercially, even though the Puritansreferred to it as the "evil weed". The industry has weathered some majorcatastrophes, including a devastating hailstorm in 1929, and an epidemic of brownspot fungus in 2000, but is now in danger of disappearing altogether, given the

    value of the land to real estate speculators. White burley, in 1865, George Webb ofBrown County, Ohio planted redburley

    seeds he had purchased, and found that a few of the seedlings had a whitish, sicklylook. The air-cured leaf was found to be more mild than other types of tobacco.

    Wild tobacco, is native to the southwestern United States, Mexico, and parts ofSouth America. Its botanical name isNicotiana rustica.
