Tobacco is a product prepared from the leaves of the tobacco plant by curing them. The plant is part of the genus Nicotiana and of the Solanaceae (nightshade) family. While more than 70 species of tobacco are known, the chief commercial crop is N. tabacum. The more potent variant N. rustica is also used around the world.
Tobacco contains the alkaloid nicotine, which is a stimulant, and harmala alkaloids. Dried tobacco leaves are mainly used for smoking in cigarettes, cigars, pipe tobacco, and flavored shisha tobacco. They can also be consumed as snuff, chewing tobacco, dipping tobacco and snus.
Tobacco use is a risk factor for many diseases; especially those affecting the heart, liver, and lungs, as well as many cancers. In 2008, the World Health Organization named tobacco 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 Taino, the Arawakan language of the Caribbean. In Taino, 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 to define medicinal herbs believed to have originated from the Arabic طُبّاق ṭubbāq (also طُباق ṭubāq), a word reportedly dating to the 9th century, as a name for various herbs.
Tobacco has long been used in the Americas, with some cultivation sites in Mexico dating back to 1400–1000 BC. Many Native American tribes have traditionally grown and used tobacco. Eastern North American tribes historically carried tobacco in pouches as a readily accepted trade item, as well as smoking it, both socially and ceremonially, such as to seal a peace treaty or trade agreement. In some populations, 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 smoking 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 account for its considerable success. The astronomer Thomas Harriot, who accompanied Sir Richard Grenville on his 1585 expedition to Roanoke Island, explains that the plant "openeth all the pores and passages of the body" so that the natives’ "bodies are notably preserved in health, and know not many grievous diseases, wherewithal we in England are often times afflicted." 
In the late 19th century, cigarettes became popular. James Bonsack created a machine that automated 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 became condemned as a health hazard, and eventually became encompassed as a cause for cancer, as well as other respiratory and circulatory diseases. In the United States, this led to the Tobacco Master Settlement Agreement, which settled the lawsuit 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. This strain of tobacco contained an unusually high amount of nicotine, nearly doubling its content from 3.2-3.5% to 6.5%. In the 1990s, this prompted the Food and Drug Administration to use this strain as evidence that tobacco companies were intentionally manipulating the nicotine content of cigarettes.
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 its enforcement in all countries to reduce the harmful effects of tobacco. This 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 (Solanaceae) indigenous to North and South America, Australia, south west Africa, and the South Pacific.
Most nightshades contain varying amounts of nicotine, a powerful neurotoxin to insects. However, tobaccos tend to contain a much higher concentration of nicotine than the others. Unlike many other Solanaceae species, they do not contain tropane alkaloids, 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 herbivores, a number of such animals have evolved 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 weeds in some places.
The types of tobacco include:
Tobacco is cultivated similarly to other agricultural products. Seeds were at first quickly scattered onto the soil. However, young plants came under increasing attack from flea beetles (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 is sown in cold frames or hotbeds, as their germination is activated by light.
After the plants are about 8 inches (20 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.
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 involves 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 this, 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 removed, and eventually, entirely harvested. As the industrial revolution took hold, harvesting wagons 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. Most tobacco in the U.S. is grown in North Carolina, Kentucky, and Virginia.
Curing and subsequent aging allow for the slow oxidation and degradation of carotenoids 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 endproducts (AGEs), a caramelization process that also adds flavor. Inhalation of these AGEs in tobacco smoke contributes to atherosclerosis and cancer. Levels of AGEs are dependent on the curing method used.
Tobacco can be cured through several methods, including:
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. 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 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 high import tariff on foreign tobacco entering China. While this tariff has been reduced from 64% in 1999 to 10% in 2004, it still has led to local, Chinese cigarettes being preferred over foreign cigarettes because of their lower cost.
|Top tobacco producers, 2014|
|No note = official figure, F = FAO Estimate, A = Aggregate (may include official, semiofficial or estimates).|
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. 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.
India's Tobacco Board is headquartered in Guntur in the state of Andhra Pradesh. India has 96,865 registered tobacco farmers 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, Punjab, Bihar, Mysore, 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.
The International Labour Office reported that the most child-laborers work in agriculture, which is one of the most hazardous types of work. The tobacco industry houses some of these working children. Use of children is widespread on farms in Argentina, 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 50-cigarettes-worth of nicotine 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 legal product.
Tobacco production requires the use of large amounts of pesticides. 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.
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 organisms 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.:3 In the US, cigarettes made with GM tobacco with reduced nicotine content are available under the market name Quest.
Tobacco is consumed in many forms and through a number of different methods. Some examples are:
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.
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. Smoking is more prevalent among men (however, the gender gap declines with age), the poor, and in transitional or developing countries.
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.
Tobacco smoking poses a risk to health due to the inhalation of poisonous chemicals in tobacco smoke such as carbon monoxide, cyanide, and carcinogens which have been proven to cause heart and lung diseases and Cancer. According to the World Health Organization (WHO), tobacco is the single greatest cause of preventable death globally. The 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."
The harms caused by inhalation of poisonous chemicals such as carbon monoxide in tobacco smoke include diseases affecting the heart and lungs, with smoking being a major risk factor for heart attacks, strokes, chronic obstructive pulmonary disease (emphysema), and cancer (particularly lung cancer, cancers of the larynx and mouth, and pancreatic cancers). Cancer is caused by inhaling carcinogenic substances present in tobacco smoke.
Inhaling secondhand tobacco smoke 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.
The addictive alkaloid nicotine is a stimulant, and popularly known as the most characteristic constituent of tobacco. Nicotine is known to produce conditioned place preference, a sign of enforcement value. Nicotine scores almost as highly as opioids on drug effect questionnaire liking scales, which are a rough indicator of addictive potential. Users may develop tolerance and dependence. 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. Tobacco's overall harm to user and self score as determined by a multi-criteria decision analysis was determined at 3 percent below cocaine, and 13 percent above amphetamines, ranking 6th most harmful of the 20 drugs assessed.
Polonium 210 is a natural contaminant of tobacco, providing additional evidence for the link between smoking and bronchial cancer. It is also extremely toxic, with one microgram being enough to kill the average adult (250,000 times more toxic than hydrogen cyanide by weight).
Tobacco has a significant economic impact. The global tobacco market has been approximated to be 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.
"Much of the disease burden and premature mortality attributable to tobacco use disproportionately affect the poor", and of the 1.22 billion smokers, 1 billion of them live in developing or transitional economies.
Smoking of tobacco is practised worldwide by over one billion people. However, 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 households' expenditure in low-income homes is on tobacco. The poorest 20% of households in Mexico spend 11% of their income on tobacco.
Tobacco advertising of tobacco products by the tobacco industry is through a variety of media, including sponsorship, particularly of sporting events. It is now one of the most highly regulated forms of marketing. Some or all forms of tobacco advertising are banned in many countries.
As of August 2014, all but eight states had laws prohibiting minors from purchasing tobacco: Alaska, Colorado, Massachusetts, Nevada, New Jersey, New York, Rhode Island, and West Virginia. All but eleven states had youth tobacco possession laws in place. These are Delaware, Hawaii, Massachusetts, Minnesota, Nevada, New Jersey, New Mexico, New York, North Carolina, Tennessee and Pennsylvania. There are still six states which prohibit youth from possessing tobacco, but allow for an exemption where parents or guardians give permission for that possession: Delaware, Georgia, Kentucky, Louisiana, Ohio, and Texas.
Tobacco is the single most preventable cause of death in the world today.
British American Tobacco plc (BAT) is a British multinational cigarette and tobacco manufacturing company headquartered in London, United Kingdom. It is the largest publicly traded tobacco company in the world.BAT has a market-leading position in over 50 countries and operations in around 180 countries. Its four largest-selling brands are its native brand Dunhill and US brands Lucky Strike, Kent and Pall Mall. Other brands that the company markets include Benson & Hedges and Rothmans.
BAT has a primary listing on the London Stock Exchange and is a constituent of the FTSE 100 Index. It has secondary listings on the Johannesburg Stock Exchange, the Nairobi Securities Exchange, the Zimbabwe Stock Exchange as well as the New York Stock Exchange.Bureau of Alcohol, Tobacco, Firearms and Explosives
The Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) is a federal law enforcement organization within the United States Department of Justice. Its responsibilities include the investigation and prevention of federal offenses involving the unlawful use, manufacture, and possession of firearms and explosives; acts of arson and bombings; and illegal trafficking and tax evasion of alcohol and tobacco products. The ATF also regulates via licensing the sale, possession, and transportation of firearms, ammunition, and explosives in interstate commerce. Many of the ATF's activities are carried out in conjunction with task forces made up of state and local law enforcement officers, such as Project Safe Neighborhoods. The ATF operates a unique fire research laboratory in Beltsville, Maryland, where full-scale mock-ups of criminal arson can be reconstructed. The agency is led by Thomas E. Brandon, Acting Director, and Ronald B. Turk, Acting Deputy Director. The ATF has 4,770 employees, and an annual budget of $1.15 billion (2012).Chewing tobacco
Chewing tobacco is a type of smokeless tobacco product consumed by placing a portion of the tobacco between the cheek and gum or upper lip teeth and chewing. Unlike dipping tobacco, it is not ground and must be manually crushed with the teeth to release flavour and nicotine. Unwanted juices are then expectorated (spat).
Chewing tobacco is typically manufactured as several varieties of product – most often as loose leaf (or scrap), pellets (tobacco "bites" or "bits"), and "plug" (a form of loose leaf tobacco condensed with a binding sweetener). Nearly all modern chewing tobaccos are produced via a process of leaf curing, cutting, fermentation and processing or sweetening. Historically, many American chewing tobacco brands (which were popular during the American Civil War era) were made with cigar clippings.Cigar
A cigar is a rolled bundle of dried and fermented tobacco leaves made to be smoked. They are produced in a wide variety of sizes and shapes. Since the 20th century, almost all cigars are made up of three distinct components: the filler, the binder leaf which holds the filler together, and a wrapper leaf, which is often the best leaf used. Often the cigar will have a band printed with the cigar manufacturer's logo. Modern cigars often come with 2 bands, especially Cuban Cigar bands, showing Limited Edition (Edición Limitada) bands displaying the year of production.
Cigar tobacco is grown in significant quantities primarily in Central America and the islands of the Caribbean, including Cuba, the Dominican Republic, Haiti, Honduras, Mexico, Ecuador, Nicaragua, Guatemala, Panama, and Puerto Rico; it is also produced in the Eastern United States, the Mediterranean countries of Italy and Spain (in the Canary Islands), and in Indonesia and the Philippines of Southeast Asia.
The origins of cigar smoking are still unknown. A Mayan ceramic pot from Guatemala dating back to the tenth century features people smoking tobacco leaves tied together with a string.
Regular cigar smoking is known to carry serious health risks including increased danger of various types of cancer and cardiovascular illnesses.Cigarette
A cigarette, also known colloquially as a fag in British English, is a narrow cylinder containing psychoactive material, usually tobacco, that is rolled into thin paper for smoking. Most cigarettes contain a "reconstituted tobacco" product known as "sheet", which consists of "recycled [tobacco] stems, stalks, scraps, collected dust, and floor sweepings", to which are added glue, chemicals and fillers; the product is then sprayed with nicotine that was extracted from the tobacco scraps, and shaped into curls. The cigarette is ignited at one end, causing it to smolder and allowing smoke to be inhaled from the other end, which is held in or to the mouth. Most modern cigarettes are filtered, although this does not make them safer. Cigarette manufacturers have described cigarettes as a drug administration system for the delivery of nicotine in acceptable and attractive form. Cigarettes are addictive (because of nicotine) and cause cancer, chronic obstructive pulmonary disease, heart disease, and other health problems.
The term cigarette, as commonly used, refers to a tobacco cigarette but is sometimes used to refer to other substances, such as a cannabis cigarette. A cigarette is distinguished from a cigar by its usually smaller size, use of processed leaf, and paper wrapping, which is typically white. Cigar wrappers are typically composed of tobacco leaf or paper dipped in tobacco extract.
Smoking rates have generally declined in the developed world, but continue to rise in developing nations. Cigarettes carry serious health risks, which are more prevalent than with other tobacco products, nicotine is also highly addictive. About half of cigarette smokers die of tobacco-related disease and lose on average 14 years of life. Cigarette use by pregnant women has also been shown to cause birth defects, including low birth weight, fetal abnormalities, and premature birth. Second-hand smoke from cigarettes causes many of the same health problems as smoking, including cancer, which has led to legislation and policy that has prohibited smoking in many workplaces and public areas. Cigarette smoke contains over 7,000 chemical compounds, including arsenic, formaldehyde, cyanide, lead, nicotine, carbon monoxide, acrolein, and other poisonous substances. Over 70 of these are carcinogenic. Additionally, cigarettes are a frequent source of mortality-associated fires in private homes, which prompted both the European Union and the United States to ban cigarettes that are not fire-standard compliant from 2011 onwards.Electronic cigarette
An electronic cigarette or e-cigarette is a handheld electronic device that simulates the experience of smoking a cigarette. It works by heating a liquid which generates an aerosol, or "vapor", that is inhaled by the user. Using e-cigarettes is commonly referred to as vaping. The liquid in the e-cigarette, called e-liquid, or e-juice, is usually made of nicotine, propylene glycol, glycerine, and flavorings. Not all e-liquids contain nicotine.The health risks of e-cigarettes are uncertain. They are likely safer than tobacco cigarettes, but are of unclear effect in relation to other methods of stopping smoking. Their long-term health effects are not known. They may help some smokers quit. When used by non-smokers, e-cigarettes can lead to nicotine addiction, and there is concern that children could start smoking after using e-cigarettes. So far, no serious adverse effects have been reported in trials. Less serious adverse effects include throat and mouth irritation, vomiting, nausea, and coughing.The majority of toxic chemicals found in tobacco smoke are absent in e-cigarette aerosol. Those present are mostly below 1% of the corresponding levels in tobacco smoke. The aerosol can contain toxicants and traces of heavy metals at levels permissible in inhalation medicines, and potentially harmful chemicals not found in tobacco smoke at concentrations permissible by workplace safety standards. However, chemical concentrations may exceed the stricter public safety limits.The modern e-cigarette was invented in 2003 by Chinese pharmacist Hon Lik. As of 2018 most e-cigarettes are made in China. Their global use has risen exponentially since they were first sold in 2004; their use is widespread in the United States and the United Kingdom. Reasons for using e-cigarettes include trying to quit smoking, reduce risk, or save money, though some use them recreationally. As of 2014, the majority of users still smoke tobacco. There are concerns that dual use of tobacco products and e-cigarettes may "delay or deter quitting". About 60% of UK users are smokers and roughly 40% are ex-smokers. In the UK use among never-smokers was negligible. Because of overlap with tobacco laws and medical drug policies, e-cigarette legislation is debated in many countries. A European directive of 2016 set standards for liquids, vaporizers, ingredients and child-proof liquid containers. As of August 2016, the US FDA extended its regulatory power to include e-cigarettes. There are around 500 brands of e-cigarettes, with global sales in excess of US$7 billion.Health effects of tobacco
Tobacco use has predominantly negative effects on human health and concern about health effects of tobacco has a long history. Research has focused primarily on cigarette tobacco smoking.Tobacco smoke contains more than fifty chemicals that cause cancer. Tobacco also contains nicotine, which is a highly addictive psychoactive drug. When tobacco is smoked, nicotine causes physical and psychological dependency. Cigarettes sold in underdeveloped countries tend to have higher tar content, and are less likely to be filtered, potentially increasing vulnerability to tobacco smoking related disease in these regions.Tobacco use is the single greatest cause of preventable death globally. As many as half of people who use tobacco die from complications of tobacco use. The World Health Organization (WHO) estimates that each year tobacco causes about 6 million deaths (about 10% of all deaths) with 600,000 of these occurring in non smokers due to second hand smoke. In the 20th century tobacco is estimated to have caused 100 million deaths. Similarly, the United States Centers for Disease Control and Prevention describes tobacco use as "the single most important preventable risk to human health in developed countries and an important cause of premature death worldwide." Currently, the number of premature deaths in the U.S. from tobacco use per year outnumber the number of workers employed in the tobacco industry 4 to 1. According to a 2014 review in the New England Journal of Medicine, tobacco will, if current smoking patterns persist, kill about 1 billion people in the 21st century, half of them before the age of 70.Tobacco use leads most commonly to diseases affecting the heart, liver and lungs. Smoking is a major risk factor for heart attacks, strokes, chronic obstructive pulmonary disease (COPD) (including emphysema and chronic bronchitis), and several cancers (particularly lung cancer, cancers of the larynx and mouth, bladder cancer, and pancreatic cancer). It also causes peripheral arterial disease and high blood pressure. The effects depend on the number of years that a person smokes and on how much the person smokes. Starting smoking earlier in life and smoking cigarettes higher in tar increases the risk of these diseases. Also, environmental tobacco smoke, or secondhand smoke, has been shown to cause adverse health effects in people of all ages. Tobacco use is a significant factor in miscarriages among pregnant smokers, and it contributes to a number of other health problems of the fetus such as premature birth, low birth weight, and increases by 1.4 to 3 times the chance of sudden infant death syndrome (SIDS). Incidence of erectile dysfunction is approximately 85 percent higher in male smokers compared to non-smokers.Several countries have taken measures to control the consumption of tobacco with usage and sales restrictions as well as warning messages printed on packaging. Additionally, smoke-free laws that ban smoking in public places such as workplaces, theaters, and bars and restaurants reduce exposure to secondhand smoke and help some people who smoke to quit, without negative economic effects on restaurants or bars. Tobacco taxes that increase the price are also effective, especially in developing countries.The coughing, throat irritation, and shortness of breath caused by smoking have always been obvious. The idea that tobacco use caused some diseases, including mouth cancers, was initially, in the late 1700s and the 1800s, widely accepted by the medical community. In the 1880s, automation slashed the cost of cigarettes, and use expanded. From the 1890s onwards, associations of tobacco use with cancers and vascular disease were regularly reported; a metaanalysis citing 167 other works was published in 1930, and concluded that tobacco use caused cancer. Increasingly solid observational evidence was published throughout the 1930s, and in 1938, Science published a paper showing that tobacco users live substantially shorter lives. Case-control studies were published in Germany in 1939 and 1943, and one in the Netherlands in 1948, but widespread attention was first drawn by five case-control studies published in 1950 by researchers from the US and UK. These studies were widely criticized as showing correlation, not causality. Follow up prospective cohort studies in the early 1950s clearly found that that smokers died faster, and were more likely to die of lung cancer and cardiovascular disease. These results were first widely accepted in the medical community, and publicized among the general public, in the mid-1960s.Hookah
A hookah (from Hindustani: हुक़्क़ा (Devanagari), حقّہ (Nastaleeq), IPA: [ˈɦʊqqaː]; also see other names), also known as the ḡalyān (Persian: قلیان), is a single- or multi-stemmed instrument for vaporizing and smoking flavored tobacco (often Mu‘assel), or sometimes cannabis or opium, whose vapor or smoke is passed through a water basin—often glass-based—before inhalation.Health risks of smoking through a hookah include exposure to toxic chemicals that are not filtered out by the water and risk of infectious disease when hookahs are shared.There are two theories regarding the origin of the hookah. The first is that following the introduction of tobacco to medieval India by the Jesuits, the waterpipe was invented by one of Akbar's physicians, Abu’l-Fath Gilani, an Iranian from Gilan, in the Indian city of Fatehpur Sikri during Mughal India; the hookah spread from the Indian subcontinent to the Near East, where the mechanism was modified. Alternatively, it could originate in the Safavid dynasty of Persia, from where it eventually spread to the east into the Indian subcontinent during that time.The word hookah is a derivative of "huqqa", a Hindustani term. Outside its native region, hookah smoking has gained popularity throughout the world, especially among younger people, largely due to immigrants from the Levant, where it is especially popular.ITC Limited
ITC Limited is an Indian multinational conglomerate company headquartered in Kolkata, West Bengal.Established in 1910 as the 'Imperial Tobacco Company of India Limited', the company was renamed as the 'India Tobacco Company Limited' in 1970 and later to 'I.T.C. Limited' in 1974. The dots in the name were removed in September 2001 for the company to be renamed as 'ITC Limited' where 'ITC' would no longer be an acronym. The company completed 100 years in 2010 and as of 2012-13, had an annual turnover of US$8.31 billion and a market capitalization of US$50 billion. It employs over 30,000 people at more than 60 locations across India and is part of Forbes 2000 list.Marlboro (cigarette)
Marlboro (US: , UK: ) is an American brand of cigarettes, currently owned and manufactured by Philip Morris USA (a branch of Altria) within the United States, and by Philip Morris International (now separate from Altria) outside the United States. Richmond, Virginia, is the location of the largest Marlboro cigarette manufacturing plant. Marlboro is the global best-selling cigarette brand since 1972.Nicotine
Nicotine is a stimulant and potent parasympathomimetic alkaloid that is naturally produced in the nightshade family of plants and used for the treatment of tobacco use disorders as a smoking cessation aid and nicotine dependence for the relief of withdrawal symptoms. Nicotine acts as a receptor agonist at most nicotinic acetylcholine receptors (nAChRs), except at two nicotinic receptor subunits (nAChRα9 and nAChRα10) where it acts as a receptor antagonist.Nicotine constitutes approximately 0.6–3.0% of the dry weight of tobacco. Usually consistent concentrations of nicotine varying from 2–7 µg/kg (20–70 millionths of a percent wet weight) are found in the edible family Solanaceae, such as potatoes, tomatoes, and eggplant. Some research indicates that the contribution of nicotine obtained from food is substantial in comparison to inhalation of second-hand smoke. Others consider nicotine obtained from food to be trivial unless exceedingly high amounts of certain vegetables are eaten. It functions as an antiherbivore chemical; consequently, nicotine was widely used as an insecticide in the past, and neonicotinoids, such as imidacloprid, are widely used.
Nicotine is highly addictive. It is one of the most commonly abused drugs. An average cigarette yields about 2 mg of absorbed nicotine; high amounts can be harmful. Nicotine induces both behavioral stimulation and anxiety in animals. Nicotine addiction involves drug-reinforced behavior, compulsive use, and relapse following abstinence. Nicotine dependence involves tolerance, sensitization, physical dependence, and psychological dependence. Nicotine dependency causes distress. Nicotine withdrawal symptoms include depressed mood, stress, anxiety, irritability, difficulty concentrating, and sleep disturbances. Mild nicotine withdrawal symptoms are measurable in unrestricted smokers, who experience normal moods only as their blood nicotine levels peak, with each cigarette. On quitting, withdrawal symptoms worsen sharply, then gradually improve to a normal state.Nicotine use as a tool for quitting smoking has a good safety history. The general medical position is that nicotine itself poses few health risks, except among certain vulnerable groups, such as youth. The International Agency for Research on Cancer indicates that nicotine does not cause cancer. Nicotine has been shown to produce birth defects in some animal species, but not others; consequently, it is considered to be a possible teratogen in humans. The median lethal dose of nicotine in humans is unknown, but high doses are known to cause nicotine poisoning.Nicotine marketing
Nicotine marketing is the marketing of nicotine-containing products or use. Traditionally, the tobacco industry markets cigarette smoking, but it is increasingly marketing other products, such as e-cigarettes. Products are marketed through social media, stealth marketing, mass media, and sponsorship (particularly of sporting events). Expenditures on nicotine marketing are in the tens of billions a year; in the US alone, spending was over US$ 1million per hour in 2016; in 2003, per-capita marketing spending was $290 per adult smoker, or $45 per inhabitant. Nicotine marketing is increasingly regulated; some forms of nicotine advertising are banned in many countries. The World Health Organization recommends a complete tobacco advertising ban.Nicotine poisoning
Nicotine poisoning describes the symptoms of the toxic effects of nicotine following ingestion, inhalation, or skin contact. Nicotine poisoning can potentially be deadly, though serious or fatal overdoses are rare. Historically, most cases of nicotine poisoning have been the result of use of nicotine as an insecticide. More recent cases of poisoning typically appear to be in the form of Green Tobacco Sickness, or due to unintended ingestion of tobacco or tobacco products or consumption of nicotine-containing plants.The estimated lower limit of a lethal dose of nicotine has been reported as between 500 and 1000 mg. Children may become ill following ingestion of one cigarette; ingestion of more than this may cause a child to become severely ill. The nicotine in the e-liquid of an electronic cigarette can be hazardous to infants and children, through accidental ingestion or skin contact. In some cases children have become poisoned by topical medicinal creams which contain nicotine.People who harvest or cultivate tobacco may experience Green Tobacco Sickness (GTS), a type of nicotine poisoning caused by skin contact with wet tobacco leaves. This occurs most commonly in young, inexperienced tobacco harvesters who do not consume tobacco.Passive smoking
Passive smoking is the inhalation of smoke, called second-hand smoke (SHS), or environmental tobacco smoke (ETS), by persons other than the intended "active" smoker. It occurs when tobacco smoke permeates any environment, causing its inhalation by people within that environment. Exposure to second-hand tobacco smoke causes disease, disability, and death. The health risks of second-hand smoke are a matter of scientific consensus. These risks have been a major motivation for smoke-free laws in workplaces and indoor public places, including restaurants, bars and night clubs, as well as some open public spaces.Concerns around second-hand smoke have played a central role in the debate over the harms and regulation of tobacco products. Since the early 1970s, the tobacco industry has viewed public concern over second-hand smoke as a serious threat to its business interests. Harm to bystanders was perceived as a motivator for stricter regulation of tobacco products. Despite the industry's awareness of the harms of second-hand smoke as early as the 1980s, the tobacco industry coordinated a scientific controversy with the purpose of stopping regulation of their products.Smoking
Smoking is a practice in which a substance is burned and the resulting smoke breathed in to be tasted and absorbed into the bloodstream. Most commonly the substance is the dried leaves of the tobacco plant which have been rolled into a small square of rice paper to create a small, round cylinder called a "cigarette". Smoking is primarily practiced 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 gasses 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 generally has negative health effects, because smoke inhalation inherently poses challenges to various physiologic processes such as respiration. Diseases related to tobacco smoking have been shown to kill approximately half of long-term smokers when compared to average mortality rates faced by non-smokers. Smoking caused over five million deaths a year from 1990 to 2015.Smoking is one of the most common forms of recreational drug use. Tobacco smoking is the most popular form, being practiced by over one billion people globally, of whom the majority are in the developing countries. Less common drugs for smoking include cannabis and opium. Some of the substances are classified as hard narcotics, like heroin, but the use of these is very limited as they are usually not commercially available. Cigarettes are primarily industrially manufactured but also can be hand-rolled from loose tobacco and rolling paper. Other smoking implements include pipes, cigars, bidis, hookahs, and bongs.
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 rituals or to allow shamans and priests to alter their minds for purposes of divination or spiritual enlightenment. After the European exploration and conquest of the Americas, the practice of smoking tobacco quickly spread to the rest of the world. In regions like India and Sub-Saharan Africa, it merged with existing practices of smoking (mostly of cannabis). In Europe, it introduced a new type of social activity and a form of drug intake which previously had been unknown.
Perception surrounding smoking has varied over time and from one place to another: holy and sinful, sophisticated and vulgar, a panacea and deadly health hazard. In the 20th century, smoking came to be viewed in a decidedly negative light, especially in Western countries. This is due to smoking tobacco being among the leading causes of many diseases such as lung cancer, heart attack, COPD, erectile dysfunction, and birth defects. The health hazards of smoking have caused many countries to institute high taxes on tobacco products, run ads to discourage use, limit ads that promote use, and provide help with quitting for those who do smoke.Smoking age
The smoking age is the minimum legal age required to purchase or smoke tobacco products. Most countries have laws that restrict those below a minimum age from legally purchasing tobacco products.Smoking ban
Smoking bans, or smoke-free laws, are public policies, including criminal laws and occupational safety and health regulations, that prohibit tobacco smoking in workplaces and other public spaces. Legislation may also define smoking as more generally being the carrying or possessing of any lit tobacco product.Tobacco industry
The tobacco industry comprises those persons and companies engaged in the growth, preparation for sale, shipment, advertisement, and distribution of tobacco and tobacco-related products. It is a global industry; tobacco can grow in any warm, moist environment, which means it can be farmed on all continents except Antarctica.
Tobacco, one of the most widely used addictive substances in the world, is a plant native to the Americas and historically one of the half-dozen most important crops grown by American farmers. More specifically, tobacco refers to any of various plants of the genus Nicotiana (especially N. tabacum) native to tropical America and widely cultivated for their leaves, which are dried and processed chiefly for smoking in pipes, cigarettes, and cigars; it is also cut to form chewing tobacco or ground to make snuff or dipping tobacco, as well as other less common preparations. From 1617 to 1793 tobacco was the most valuable staple export from the English American mainland colonies and the United States. Until the 1960s, the United States not only grew but also manufactured and exported more tobacco than any other country.Tobacco is an agricultural commodity product, similar in economic terms to agricultural foodstuffs: the price is in part determined by crop yields, which vary depending on local weather conditions. The price also varies by specific species or cultivar grown, the total quantity on the market ready for sale, the area where it is grown, the health of the plants, and other characteristics individual to product quality.
Since 1964 conclusive medical evidence of the deadly effects of tobacco consumption has led to a sharp decline in official support for producers and manufacturers of tobacco, although it contributes to the agricultural, fiscal, manufacturing, and exporting sectors of the economy. Laws around the world now often have some restrictions on smoking, but almost 6 trillion cigarettes are still produced each year, representing over a 12% increase since the year 2000. China accounts for over 40% of current world production. Tobacco is often heavily taxed to gain revenues for governments and as an incentive for people not to smoke.Tobacco smoking
Tobacco smoking is the practice of smoking tobacco and inhaling tobacco smoke (consisting of particle and gaseous phases). (A more broad definition may include simply taking tobacco smoke into the mouth, and then releasing it, as is done by some with tobacco pipes and cigars.) The practice is believed to have begun as early as 5000–3000 BC in Mesoamerica and South America. Tobacco was introduced to Eurasia in the late 17th century by European colonists, where it followed common trade routes. The practice encountered criticism from its first import into the Western world onwards but embedded itself in certain strata of a number of societies before becoming widespread upon the introduction of automated cigarette-rolling apparatus.German scientists identified a link between smoking and lung cancer in the late 1920s, leading to the first anti-smoking campaign in modern history, albeit one truncated by the collapse of Nazi Germany at the end of World War II. In 1950, British researchers demonstrated a clear relationship between smoking and cancer. Evidence continued to mount in the 1980s, which prompted political action against the practice. Rates of consumption since 1965 in the developed world have either peaked or declined. However, they continue to climb in the developing world.Smoking is the most common method of consuming tobacco, and tobacco is the most common substance smoked. The agricultural product is often mixed with additives and then combusted. The resulting smoke is then inhaled and the active substances absorbed through the alveoli in the lungs or the oral mucosa. Combustion was traditionally enhanced by addition of potassium or nitrates. Many substances in cigarette smoke trigger chemical reactions in nerve endings, which heighten heart rate, alertness and reaction time, among other things. Dopamine and endorphins are released, which are often associated with pleasure. As of 2008 to 2010, tobacco is used by about 49% of men and 11% of women aged 15 or older in fourteen low-income and middle-income countries (Bangladesh, Brazil, China, Egypt, India, Mexico, Philippines, Poland, Russia, Thailand, Turkey, Ukraine, Uruguay and Vietnam), with about 80% of this usage in the form of smoking. The gender gap tends to be less pronounced in lower age groups.Many smokers begin during adolescence or early adulthood. During the early stages, a combination of perceived pleasure acting as positive reinforcement and desire to respond to social peer pressure may offset the unpleasant symptoms of initial use, which typically include nausea and coughing. After an individual has smoked for some years, the avoidance of withdrawal symptoms and negative reinforcement become the key motivations to continue.
A study of first smoking experiences of seventh-grade students found out that the most common factor leading students to smoke is cigarette advertisements. Smoking by parents, siblings and friends also encourages students to smoke.
