Tobacco is the common name of several plants in the ''Nicotiana
and the Solanaceae
, and the general term for any product prepared from the cured leaves
of the tobacco plant. More than 70 species
of tobacco are known, but the chief commercial crop is ''N. tabacum''
. The more potent variant ''N. rustica''
is also used in some countries.
Tobacco contains the highly addictive stimulant alkaloid nicotine
as well as harmala alkaloid
s. Dried tobacco leaves are mainly used for smoking
s and cigar
s, as well as pipes
. They can also be consumed as snuff
, chewing tobacco
, dipping tobacco
Tobacco use is a cause or risk factor for many deadly diseases; especially those affecting the heart
, and lungs
, as well as many cancers
. In 2008, the World Health Organization
named tobacco use as the world's single greatest preventable cause of death.
The English word ''tobacco'' originates from the Spanish and Portuguese word "tabaco". The precise origin of this word is disputed, but it is generally thought to have derived at least in part, from 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'').
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 (also ), a word reportedly dating to the 9th century, referring to various herbs.

Tobacco has long been used in the Americas, with some cultivation sites in Mexico dating back to 1400–1000 BCE. Many Native American tribes traditionally grow and use tobacco. Historically, people from the Indigenous peoples of the Northeastern Woodlands|Northeast Woodlands cultures
have carried tobacco in pouches as a readily accepted trade item. It was smoked both socially and ceremonially
, such as to seal a peace treaty or trade agreement. In some Native cultures, tobacco is seen as a gift from the Creator
, with the ceremonial tobacco smoke carrying one's thoughts and prayers to the Creator.
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
, 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 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.
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."
Production of tobacco for smoking, chewing, and snuffing became a major industry in Europe and its colonies by 1700.
Tobacco has been a major cash crop
in Cuba and in other parts of the Caribbean since the 18th century. Cuban cigars are world-famous.
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.
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.
In the 1970s, Brown & Williamson
cross-bred a strain of tobacco to produce Y1
, a strain containing an unusually high nicotine content, nearly doubling from 3.2-3.5% to 6.5%. In the 1990s, this prompted the Food and Drug Administration
to allege that tobacco companies
were intentionally manipulating the nicotine content of cigarette
In 2003, in response to growth of tobacco use in developing countries, the World Health Organization successfully rallied 168 countries to sign the Framework Convention on Tobacco Control. The convention is designed to push for effective legislation and enforcement in all countries to reduce the harmful effects of tobacco.
The desire of many addicted smokers to quit has led to the development of tobacco cessation products
Many species of tobacco are in the genus of herbs ''Nicotiana''. It is part of the nightshade family
) indigenous to North
and South America
, south west Africa
, and the South Pacific
Most nightshades contain varying amounts of nicotine
, a powerful neurotoxin
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 other piperidine
alkaloids (varying between species) to deter most herbivore
s, a number of such animals have evolve
d the ability to feed on ''Nicotiana'' species without being harmed. Nonetheless, tobacco is unpalatable to many species due to its other attributes. For example, although the cabbage looper
is a generalist pest, tobacco's gummosis and trichomes can harm early larvae survival. As a result, some tobacco plants (chiefly ''N. glauca'') have become established as invasive weed
s in some places.
The types of tobacco include:
* 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
is used in some chewing tobaccos, moist snuff, some cigarettes, and as a condiment in pipe tobacco blends. Another fire-cured tobacco is 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
* 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
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.
* 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.
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 Cuba
n tobaccos that emerged around the time of Columbus
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
, 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).
was developed in 1824 through the technique of pressure-fermentation of local tobacco by a farmer, Pierre Chenet. Considered the truffle
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.
* Shade tobacco
is cultivated in Connecticut
. 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
industry has weathered some major 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.
* 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
seeds he had purchased, and found a few of the seedlings had a whitish, sickly look, which became white burley.
* 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. In the United States, tobacco is often fertilized with the mineral apatite
, which partially starves the plant of nitrogen
, to produce a more desired flavor.
After the plants are about 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.
Tobacco is cultivated annually, and can be harvested
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
are the leaders in tobacco production, followed by Tennessee
, South Carolina
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 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
. Levels of AGEs are dependent on the curing method used.
Tobacco can be cured through several methods, including:
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.
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.
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.
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 ''fermenting
'' or ''sweating''. Cavendish
undergoes fermentation pressed in a ''casing'' solution containing sugar and/or flavoring.
thumb|Tobacco production in Portuguese Timor
in the 1930s
Production of tobacco leaf increased by 40% between 1971, when 4.2 million tons of leaf were produced, and 1997, when 5.9 million tons of leaf were produced.
[Food and Agriculture Organization of the United Nations. "Projection of tobacco production, consumption and trade for the year 2010." Rome, 2003.]
According to the Food and Agriculture organization of the UN, tobacco leaf production was expected to hit 7.1 million tons by 2010. This number is a bit lower than the record-high production of 1992, when 7.5 million tons of leaf were produced.
[The Food and Agriculture Organization of the United Nations.''Higher World Tobacco use expected by 2010-growth rates slowing down.'' (Rome, 2004).]
The production growth was almost entirely due to increased productivity by developing nations, where production increased by 128%.
During that same time, production in developed countries actually decreased.
China's increase in tobacco production was the single biggest factor in the increase in world production. China's share of the world market increased from 17% in 1971 to 47% in 1997.
This growth can be partially explained by the existence of a low import tariff on foreign tobacco entering China. While this tariff has been reduced from 66% in 1999 to 10% in 2004, it still has led to local, Chinese cigarettes being preferred over foreign cigarettes because of their lower cost.
Every year, about 6.7 million tons of tobacco are produced throughout the world. The top producers of tobacco are China (39.6%), India (8.3%), Brazil (7.0%) and the United States (4.6%).
Around the peak of global tobacco production, 20 million rural Chinese households were producing tobacco on 2.1 million hectares of land.
[Food and Agriculture Organization of the United Nations. "Issues in the Global Tobacco 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. As noted above, despite the income generated for the state by profits from state-owned tobacco companies and the taxes paid by companies and retailers, China's government has acted to reduce tobacco use.
's Tobacco Board is headquartered in Guntur
in the state of Andhra Pradesh
. India has 96,865 registered tobacco farmers
[Shoba, John and Shailesh Vaite. Tobacco and Poverty: Observations from India and Bangladesh. Canada, 2002.]
and many more who are not registered. In 2010, 3,120 tobacco product manufacturing facilities were operating in all of India. Around 0.25% of India's cultivated land is used for tobacco production.
Since 1947, the Indian government
has supported growth in the tobacco industry. India has seven tobacco research centers, located in Tamil Nadu
, Andhra Pradesh
, and West Bengal
houses the core research institute.
In Brazil, around 135,000 family farmers cite tobacco production as their main economic activity.
Tobacco has never exceeded 0.7% of the country's total cultivated area.
In the southern regions of Brazil, Virginia, and Amarelinho, flue-cured tobacco, as well as burley and Galpão Comum air-cured tobacco, are produced. These types of tobacco are used for cigarettes. In the northeast, darker, air- and sun-cured tobacco is grown. These types of tobacco are used for cigars, twists, and dark cigarettes.
Brazil's government has made attempts to reduce the production of tobacco but has not had a successful systematic antitobacco farming initiative. Brazil's government, however, provides small loans for family farms, including those that grow tobacco, through the ''Programa Nacional de Fortalecimento da Agricultura Familiar''.
Problems in production
The International Labour Office reported that the most child-laborers work in agriculture, which is one of the most hazardous types of work.
[ILO. International Hazard Datasheets on Occupations: Field Crop Worker]
The tobacco industry houses some of these working children. Use of children is widespread on farms in Brazil, China, India, Indonesia, Malawi, and Zimbabwe. While some of these children work with their families on small, family-owned farms, others work on large plantations.
In late 2009, reports were released by the London-based human-rights group Plan International
, claiming that child labor was common on Malawi (producer of 1.8% of the world's tobacco
) tobacco farms. The organization interviewed 44 teens, who worked full-time on farms during the 2007-8 growing season. The child-laborers complained of low pay and long hours, as well as physical and sexual abuse by their supervisors. They also reported suffering from Green tobacco sickness
, a form of nicotine poisoning. When wet leaves are handled, nicotine from the leaves gets absorbed in the skin and causes nausea, vomiting, and dizziness. Children were exposed to levels of nicotine equivalent to smoking 50 cigarettes, just through direct contact with tobacco leaves. This level of nicotine in children can permanently alter brain structure and function.
Major tobacco companies have encouraged global tobacco production. Philip Morris
, British American Tobacco
, and Japan Tobacco
each own or lease tobacco-manufacturing facilities in at least 50 countries and buy crude tobacco leaf from at least 12 more countries. This encouragement, along with government subsidies, has led to a glut in the tobacco market. This surplus has resulted in lower prices, which are devastating to small-scale tobacco farmers. According to the World Bank, between 1985 and 2000, the inflation-adjusted price of tobacco dropped 37%. Tobacco is the most widely smuggled
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.
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. Coupled with child labor, pesticides pose an even greater threat. Early exposure to pesticides may increase a child's lifelong cancer risk, as well as harm his or her nervous and immune systems.
As with all crops, tobacco crops extract nutrients (such as phosphorus
, and potassium
) from soil, decreasing its fertility.
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.
Brazil alone uses the wood of 60 million trees per year for curing, packaging, and rolling cigarettes.
In 2017 WHO released a study on the environmental effects of tobacco.
Several tobacco plants have been used as model organism
s in genetics
. Tobacco BY-2 cells
, derived from ''N. tabacum'' cultivar
'Bright Yellow-2', are among the most important research tools in plant cytology
. Tobacco has played a pioneering role in callus
culture research and the elucidation of the mechanism by which kinetin
works, laying the groundwork for modern agricultural biotechnology
. The first genetically modified plant was produced in 1982, using ''Agrobacterium tumefaciens
'' to create an antibiotic-resistant tobacco plant.
This research laid the groundwork for all genetically modified crops
Because of its importance as a research tool, transgenic tobacco was the first 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.
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.
Currently, only the US is producing GM tobacco.
The Chinese virus-resistant tobacco was withdrawn from the market in China in 1997. From 2002 to 2010, cigarettes made with GM tobacco with reduced nicotine content were available in the US under the market name Quest.
Tobacco is consumed in many forms and through a number of different methods. Some examples are:
are thin, often flavoured cigarettes from India made of tobacco wrapped in a tendu
leaf, and secured with coloured thread at one end.
* 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
s are tightly rolled bundles of dried and fermented tobacco, which are ignited so their smoke may be drawn into the smokers' mouths.
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.
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.
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.
is a single- or multistemmed (often glass-based) water pipe for smoking. Hookahs were first used in India and Persia; 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

, 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.
is a ground smokeless tobacco product, inhaled or "snuffed" through the nose. If referring specifically to the orally consumed moist snuff, see dipping tobacco
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 TSNA
* Tobacco edibles, often in the form of an infusion or a spice, have gained popularity in recent years.
* Tobacco pipes
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 North America
to stimulate respiration,, injecting the smoke with a rectal tube. Later, Europeans emulated the Americans. Tobacco resuscitation kits consisting of a pair of bellows and a tube were provided by the Royal Humane Society of London and placed at various points along the Thames.
* Tobacco water
is a traditional organic insecticide
used in domestic gardening
. Tobacco dust can be used similarly. It is produced by boiling strong tobacco in water, or by steeping the tobacco in water for a longer period. When cooled, the mixture can be applied as a spray, or 'painted' on to the leaves of garden plants, where it kills insects. Tobacco is, however, banned from use as pesticide in certified organic production by the USDA's National Organic Program
* Topical tobacco paste
is sometimes used as a treatment for wasp
, fire ant
, and bee sting
s. An amount equivalent to the contents of a cigarette is mashed in a cup with about a half a teaspoon of water to make a paste that is then applied to the affected area.
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.
Following the American Civil War
, the use of tobacco, primarily in cigars, became associated with masculinity
and power. Today, tobacco use is often stigmatized; this has spawned quitting associations and antismoking campaigns. Bhutan
is the only country in the world where tobacco sales are illegal. Due to its propensity for causing detumescence
and erectile dysfunction, some studies have described tobacco as an anaphrodisiacal substance.
In Christian denomination
s of the conservative holiness movement
, such as the Allegheny Wesleyan Methodist Connection
and Evangelical Wesleyan Church
, the use of tobacco and other drugs is prohibited;
¶42 of the 2014 Book of Discipline
of the Allegheny Wesleyan Methodist Connection states:
, a monotheistic religion from India, considers tobacco consumption as a taboo and very bad for health and spirituality. Initiated Sikhs are never to consume tobacco in any form.
Research on tobacco use is limited mainly to smoking, which has been studied more extensively than any other form of consumption. An estimated 1.1 billion people, and up to one-third of the adult population, use tobacco in some form.
[Saner L. Gilman and Zhou Xun, "Introduction" in ''Smoke''; p. 26]
Smoking is more prevalent among men
["Guindon & Boisclair" 2004, pp. 13-16.]

A study published in Morbidity and Mortality Weekly Report
found that in 2019 approximately one in four youths (23.0%) in the U.S. had used a tobacco product during the past 30 days. This represented approximately three in 10 high school students (31.2%) and approximately one in eight middle school students (12.5%).
Rates of smoking continue to rise in developing countries, but have leveled off or declined in developed countries
. Smoking rates in the United States have dropped by half from 1965 to 2006, falling from 42% to 20.8% in adults. In the developing world, tobacco consumption is rising by 3.4% per year.
Hazardous health effects of tobacco smoking
Tobacco smoking harms health because of the toxic chemicals in tobacco smoke, including carbon monoxide
, 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
, tobacco-specific nitrosamines
, and phenols
contribute to the harmful effects of smoking.
According to the World Health Organization, tobacco is the single greatest cause of preventable death globally.
WHO estimates that tobacco caused 5.4 million deaths in 2004
and 100 million deaths over the course of the 20th century.
Similarly, the United States Centers for Disease Control and Prevention
describe tobacco use as "the single most important preventable risk to human health in developed countries and an important cause of premature death worldwide."
Due to these health consequences, it is estimated that a 10 hectare (approximately 24.7 acre) field of tobacco used for cigarettes causes 30 deaths per year – 10 from lung cancer and 20 from cigarette-induced diseases like cardiac arrest, gangrene, bladder cancer, mouth cancer, etc.
The harms caused by inhaling tobacco smoke include diseases of the heart
s, with smoking being a major risk factor for heart attacks
s, chronic obstructive pulmonary disease
(emphysema), and cancer
(particularly cancers of the lungs
, larynx, mouth
, and 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. Heart disease caused by secondhand smoke kills around 46,000 nonsmokers every year.
In children, exposure to secondhand tobacco smoke is associated with a higher incidence and severity of respiratory illnesses, middle ear disease, and asthma attacks. Each year in the United States, secondhand smoke exposure causes 24,500 infants to be born with low birthweight, 71,900 preterm births, 202,300 episodes of asthma, and 790,00 health care visits for ear infections.
The addictive alkaloid nicotine
is a stimulant
, and popularly known as the most characteristic constituent of tobacco. In drug effect preference questionnaires, a rough indicator of addictive potential, nicotine scores almost as highly as opioids. Users typically develop tolerance
. Nicotine is known to produce conditioned place preference, a sign of psychological enforcement value. In one medical study, tobacco's overall harm to user and self was determined at 3 percent below cocaine, and 13 percent above amphetamines, ranking 6th most harmful of the 20 drugs assessed.

Tobacco has a significant economic impact. The global tobacco market in 2010 was estimated at US$760 billion, excluding China. Statistica
estimates that in the U.S. alone, the tobacco industry has a market of US$121 billion, despite the fact the CDC
reports that US smoking rates are declining steadily. 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.
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.
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. Women's smoking rates vary more widely but rarely equal male rates.
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.

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.
