Tobacco is the common name of several plants in the genus Nicotiana of the family Solanaceae, and the general term for any product prepared from the cured leaves of these plants. 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.

Contents

Dried tobacco leaves are mainly used for smoking in cigarettes and cigars, as well as pipes and shishas. They can also be consumed as snuff, chewing tobacco, dipping tobacco, and snus.

Tobacco contains the highly addictive stimulant alkaloid nicotine as well as harmala alkaloids. [3] Tobacco use is a cause or risk factor for many deadly diseases, especially those affecting the heart, liver, 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. [4]

Etymology

The English word tobacco originates from the Spanish word "tabaco". [5] 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). [6] [5]

However, perhaps coincidentally, similar words in Spanish, Portuguese and Italian were used from 1410 for certain medicinal herbs. These probably derived from the Arabic طُبّاقṭubbāq (also طُباقṭubāq), a word reportedly dating to the ninth century, referring to various herbs. [7] [8]

Tobacco has long been used in the Americas, with some cultivation sites in Mexico dating back to 1400–1000 BC. [9] Many Native American tribes traditionally grow and use tobacco. [10] Historically, people from the 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. [11] [12] 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. [13]

Popularization

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. [14]

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." [15]

Production of tobacco for smoking, chewing, and snuffing became a major industry in Europe and its colonies by 1700. [16] [17]

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. [18]

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. [19] [20]

Contemporary

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

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 to 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 cigarettes.[ citation needed ]

The desire of many addicted smokers to quit has led to the development of tobacco cessation products. [21]

In 2003, in response to growth of tobacco use in developing countries, the World Health Organization [22] 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. [23] Between 2019 and 2021, concerns about increased COVID-19 health risks due to tobacco consumption facilitated smoking reduction and cessation. [24]

Biology

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. [25]

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, [26] 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. [27] As a result, some tobacco plants (chiefly N. glauca) have become established as invasive weeds in some places.

Types

The types of tobacco include:

Parasites

Tobacco, alongside its related products, can be infested by parasites such as the Lasioderma serricorne (tobacco beetle) and the Ephestia elutella (tobacco moth), which are the most widespread and damaging parasites to the tobacco industry. [29] Infestation can range from the tobacco cultivated in the fields to the leaves used for manufacturing cigars, cigarillos, cigarettes, etc. [29] Both the larvae of Lasioderma serricorne and caterpillars of Ephestia elutella are considered a pest. [29]

Production

Cultivation

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 seeds are sown in cold frames or hotbeds, as their germination is activated by light. [30] 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 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. [31]

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 and Kentucky are the leaders in tobacco production, followed by Tennessee, Virginia, Georgia, South Carolina and Pennsylvania. [32]

Curing

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. [33] Levels of AGEs are dependent on the curing method used.

Tobacco can be cured through several methods, including:

Some tobaccos go through a second stage of curing, known as fermenting or sweating. [36] Cavendish undergoes fermentation pressed in a casing solution containing sugar and/or flavoring. [37]

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. [39] 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. [40] The production growth was almost entirely due to increased productivity by developing nations, where production increased by 128%. [41] During that same time, production in developed countries actually decreased. [40] 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. [39] 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, [42] it still has led to local, Chinese cigarettes being preferred over foreign cigarettes because of their lower cost.

Every year, about 5.9 million tons of tobacco are produced throughout the world. The top producers of tobacco are China (36.3%), India (12.9%), Brazil (11.9%) and Zimbabwe (3.5%). [43]

China

Around the peak of global tobacco production, 20 million rural Chinese households were producing tobacco on 2.1 million hectares of land. [44] 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. [45] 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. [46]

India

India's Tobacco Board is headquartered in Guntur in the state of Andhra Pradesh. [47] India has 96,865 registered tobacco farmers [48] and many more who are not registered. In 2010, 3,120 tobacco product manufacturing facilities were operating in all of India. [49] Around 0.25% of India's cultivated land is used for tobacco production. [50]

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.

Brazil

In Brazil, around 135,000 family farmers cite tobacco production as their main economic activity. [44] Tobacco has never exceeded 0.7% of the country's total cultivated area. [51] 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. [51] 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. [52]

Problems in production

Child labor

The International Labour Office reported that the most child-laborers work in agriculture, which is one of the most hazardous types of work. [53] [ failed verification see discussion ] The tobacco industry houses some of these working children. Use of children is widespread on farms in Brazil, China, India, Indonesia, Malawi, and Zimbabwe. [54] 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 [39] ) 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. [55] They also reported experiencing 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. [53] [ failed verification see discussion ]

Economy

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. [56] 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%. [57] Tobacco is the most widely smuggled legal product. [58]

Environment

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. [59] 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. [60] 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. [61]

As with all crops, tobacco crops extract nutrients (such as phosphorus, nitrogen, and potassium) from soil, decreasing its fertility. [62]

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. [62] Brazil alone uses the wood of 60 million trees per year for curing, packaging, and rolling cigarettes. [59]

In 2017 WHO released a study on the environmental effects of tobacco. [63]

Research

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. [64] 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. [65] This research laid the groundwork for all genetically modified crops. [66]

Genetic modification

Because of its importance as a research tool, transgenic tobacco was the first genetically modified (GM) crop to be tested in field trials, in the United States and France in 1986; China became the first country in the world to approve commercial planting of a GM crop in 1993, which was tobacco. [67]

Field trials

Many varieties of transgenic tobacco have been intensively tested in field trials. Agronomic traits such as resistance to pathogens (viruses, particularly to the tobacco mosaic virus (TMV); fungi; bacteria and nematodes); weed management via herbicide tolerance; resistance against insect pests; resistance to drought and cold; and production of useful products such as pharmaceuticals; and use of GM plants for bioremediation, have all been tested in over 400 field trials using tobacco. [68]

Production

Currently, only the US is producing GM tobacco. [67] [68] The Chinese virus-resistant tobacco was withdrawn from the market in China in 1997. [69] :3 From 2002 to 2010, cigarettes made with GM tobacco with reduced nicotine content were available in the US under the market name Quest. [68] [70]

Consumption

Tobacco is consumed in many forms and through a number of different methods. Some examples are:

Impact

Social

Smoking in public was, for a long time, reserved for men, and when done by women was sometimes associated with promiscuity; in Japan, during the Edo period, prostitutes and their clients often approached one another under the guise of offering a smoke. The same was true in 19th-century Europe. [81]

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. [82] [83] Bhutan is the only country in the world where tobacco sales are illegal. [84] Due to its propensity for causing detumescence and erectile dysfunction, some studies have described tobacco as an anaphrodisiacal substance. [85]

Religion

Christianity

In Christian denominations 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; [86] :37 ¶42 of the 2014 Book of Discipline of the Allegheny Wesleyan Methodist Connection states: [86] [ page needed ]

In the judgment of The Allegheny Wesleyan Methodist Connection (Original Allegheny Conference), the use of tobacco is a great evil, unbecoming a Christian, a waste of the Lord's money, and a defilement of the body, which should be the temple of the Holy Ghost. We do, therefore, most earnestly require our members to refrain from its cultivation, manufacture, and sale, and to abstain from its use in all forms, for Jesus' sake. We will not receive as members into our churches nor will we ordain or license to preach or to exhort, persons who use, cultivate, manufacture, or sell tobacco. Using tobacco by a member of a church or of the Conference after being received from this date (June 28, 1927) is a violation of the law of the church, and the offending party should be dealt with according to the judiciary rules. [86] :44

Members of The Church of Jesus Christ of Latter-day Saints (popularly known as Mormons) adhere to the Word of Wisdom, a religious health code that is interpreted as prohibiting the consumption of tobacco as well as alcohol, coffee, and tea. [87]

Islam

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

Sikhism

Sikhism, 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. [88]

Demographic

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. [89] Smoking is more prevalent among men [90] (however, the gender gap declines with age), [91] [92] the poor, and in transitional or developing countries. [93] 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%). [94]

Rates of smoking continue to rise in developing countries, but have leveled off or declined in developed countries. [95] Smoking rates in the United States have dropped by half from 1965 to 2006, falling from 42% to 20.8% in adults. [96] In the developing world, tobacco consumption is rising by 3.4% per year. [97]

Health effects

Chemicals

Tobacco smoking harms health because of the toxic chemicals in tobacco smoke, including carbon monoxide, cyanide, and carcinogens, which have been proven to cause heart and lung diseases and cancer. Thousands of different substances in cigarette smoke, including polycyclic aromatic hydrocarbons (such as benzopyrene), formaldehyde, cadmium, nickel, arsenic, tobacco-specific nitrosamines, and phenols contribute to the harmful effects of smoking. [98]

According to the World Health Organization, tobacco is the single greatest cause of preventable death globally. [99] WHO estimates that tobacco caused 5.4 million deaths in 2004 [100] and 100 million deaths over the course of the 20th century. [101] 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." [102] 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. [103]

The harms caused by inhaling tobacco smoke include diseases of the heart and lungs, with smoking being a major risk factor for heart attacks, strokes, 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. [104]

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 790,000 health care visits for ear infections. [105]

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. [106] Users typically develop tolerance and dependence. [107] [108] Nicotine is known to produce conditioned place preference, a sign of psychological enforcement value. [109] In one medical study, tobacco's overall harm to user and self was determined at three percent below cocaine, and 13 percent above amphetamines, ranking sixth most harmful of the 20 drugs assessed. [110]

Radioactivity

Polonium-210 is a radioactive trace contaminant of tobacco, providing additional explanation for the link between smoking and bronchial cancer. [111] The radioactive particles build up over time in the lungs and a UCLA study has estimated that the radiation from 25 years of smoking would cause over 120 deaths per thousand smokers. [112]

Economic

Tobacco has a significant economic impact. The global tobacco market in 2010 was estimated at US$760 billion, excluding China. [113] The global revenues from tobacco taxes in 2013-2014 was approximately $269 billion.

In China, cigarette manufacturing is one of the few profitable state-owned industries. For example, in 1998 the 1 429 state-owned enterprises in Yunnan province had revenue of Renminbi (RMB) 69.1 billion (US$8.3 billion) while 8 cigarette manufacturing plants alone accounted for about 53 percent (or RMB 36.2 billion) of total provincial industry sales. [114] The Chinese government also collects tax on tobacco products. Tax revenues from cigarettes increased from 740 to 842 billion Chinese yuan between 2014 and 2016. This generated an additional 101 billion Chinese yuan in tax revenues for the government. [115]

In India, tobacco generates approximately 20 billion Indian Rupees (US$0.45 billion) of income per annum as a result of employment, income and government revenue. [116]

Statistica estimates that in the U.S. alone, the tobacco industry has a market of US$121 billion, [117] despite the fact the CDC reports that US smoking rates are declining steadily. [118] In terms of health expenditures, cigarette smoking contributed to more than $225 billion (or 11.7%) of annual healthcare spending in the U.S. in 2014. [119] Smoking-attributable healthcare spending increased more than 30% for Medicaid between 2010 and 2014. [119]

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. [120]

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. [93] 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. [121]

Tobacco users must also spend a significant amount of money on cigarettes to maintain regular use, as tobacco products are often heavily taxed by governments. For example, a pack a day smoker in the state of New York would have to spend around $4,690.25 a year on cigarettes alone. [122]

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. [123]

Advertising

The tobacco industry advertises its products through a variety of media, including sponsorship, particularly of sporting events. Because of the health risks of these products, this is now one of the most highly regulated forms of marketing. Some or all forms of tobacco advertising are banned in many countries. [124]

Environment

Tobacco does a great deal to pollute environment, cigarette bumps or packages can easily end up in seas or lakes. Tobacco by leading to disease, then leads environmental pollution it can drive up medication use, medication industries contribute to pollution, by the [over-]/production process, by the (proper or not) disposal of medication, by packaging, etc.

<span class="mw-page-title-main">Cigar</span> Rolled bundle of dried and fermented tobacco leaves made to be smoked

A cigar is a rolled bundle of dried and fermented tobacco leaves made to be smoked. Cigars are produced in a variety of sizes and shapes. Since the 20th century, almost all cigars are made of three distinct components: the filler, the binder leaf which holds the filler together, and a wrapper leaf, which is often the highest quality leaf used. Often there will be a cigar band printed with the cigar manufacturer's logo. Modern cigars often come with two bands, especially Cuban cigar bands, showing Limited Edition bands displaying the year of production.

<span class="mw-page-title-main">Cigarette</span> Small roll of cut tobacco designed to be smoked

A cigarette is a narrow cylinder containing a combustible material, typically tobacco, that is rolled into thin paper for smoking. The cigarette is ignited at one end, causing it to smolder; the resulting smoke is orally inhaled via the opposite end. Cigarette smoking is the most common method of tobacco consumption. The term cigarette, as commonly used, refers to a tobacco cigarette, but the word is sometimes used to refer to other substances, such as a cannabis cigarette or an herbal cigarette. A cigarette is distinguished from a cigar by its usually smaller size, use of processed leaf, and paper wrapping, which is typically white.

<span class="mw-page-title-main">Tobacco industry</span> Persons and companies that produce tobacco-related products

The tobacco industry comprises those persons and companies who are 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.

<span class="mw-page-title-main">Tobacco smoke</span> Aerosol produced by the incomplete combustion of tobacco

Tobacco smoke is a sooty aerosol produced by the incomplete combustion of tobacco during the smoking of cigarettes and other tobacco products. Temperatures in burning cigarettes range from about 400 °C between puffs to about 900 °C during a puff. During the burning of the cigarette tobacco, thousands of chemical substances are generated by combustion, distillation, pyrolysis and pyrosynthesis. Tobacco smoke is used as a fumigant and inhalant.

<span class="mw-page-title-main">Tobacco smoking</span> Practice of burning tobacco and ingesting the resulting smoke

Tobacco smoking is the practice of burning tobacco and ingesting the smoke that is produced. The smoke may be inhaled, as is done with cigarettes, or simply released from the mouth, as is generally done with 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.

Snus is a tobacco product, originating from a variant of dry snuff in early 18th-century Sweden. It is placed between the upper lip and gum for extended periods, as a form of sublabial administration. Snus is not fermented. Although used similarly to American dipping tobacco, snus does not typically result in the need for spitting and, unlike naswar, snus is steam-pasteurized.

A beedi is a thin cigarette or mini-cigar filled with tobacco flake and commonly wrapped in a tendu or Piliostigma racemosum leaf tied with a string or adhesive at one end. It originates from the Indian subcontinent. The name is derived from the Marwari word beeda—a mixture of betel nuts, herbs, and spices wrapped in a leaf. It is a traditional method of tobacco use throughout South Asia and parts of the Middle East, where beedies are popular and inexpensive. In India, beedi consumption outpaces conventional cigarettes accounting for 48% of all Indian tobacco consumption in 2008.

<i>Nicotiana tabacum</i> Species of plant

Nicotiana tabacum, or cultivated tobacco, is an annually grown herbaceous plant of the Nicotiana genus. The plant is tropical in origin, is commonly grown throughout the world, and is often found in cultivation. It grows to heights between 1 and 2 meters. Research is ongoing into its ancestry among wild Nicotiana species, but it is believed to be a hybrid of Nicotiana sylvestris, Nicotiana tomentosiformis, and possibly Nicotiana otophora. It is the most commonly grown of all plants in the genus Nicotiana, the plants' leaves commercially grown to be processed into tobacco.

<span class="mw-page-title-main">Herbal cigarette</span> Cigarette containing herbs in lieu of tobacco

Herbal cigarettes are cigarettes that usually do not contain any tobacco or nicotine, instead being composed of a mixture of various herbs and/or other plant material. However, Chinese herbal cigarettes contain tobacco and nicotine with herbs added, unlike European and North American herbal cigarettes which have tobacco and nicotine omitted. Like herbal smokeless tobacco, they are often used as a substitute for standard tobacco products. Herbal cigarettes are often advertised as a smoking cessation aid. They are also used in acting scenes by performers who are non-smokers, or where anti-smoking legislation prohibits the use of tobacco in public spaces. Herbal cigarettes can carry carcinogens.

Tobacco harm reduction (THR) is a public health strategy to lower the health risks to individuals and wider society associated with using tobacco products. It is an example of the concept of harm reduction, a strategy for dealing with the use of drugs. Tobacco smoking is widely acknowledged as a leading cause of illness and death, and reducing smoking is vital to public health.

<span class="mw-page-title-main">Smoking</span> Practice of inhaling a burnt substance for psychoactive effects

Smoking is a practice in which a substance is burned and the resulting smoke is typically breathed in to be tasted and absorbed into the bloodstream. Most commonly, the substance used is the dried leaves of the tobacco plant, which have been rolled into a small rectangle of rolling paper to create a small, round cylinder called a cigarette. Smoking is primarily practised 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 gases 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.

Dokha is a tobacco product, consisting of dried and finely shredded tobacco flakes mixed with herbs and spices. It originated in Iran during the 15th century. Unlike hookah tobacco, dokha is not cured with molasses. Users smoke the tobacco blend in small quantities using a pipe called a midwakh. Because the midwakh pipe is used almost exclusively for smoking dokha, the terms are often used interchangeably.

<span class="mw-page-title-main">Cultivation of tobacco</span>

The cultivation of tobacco usually takes place annually. The tobacco is germinated in cold frames or hotbeds and then transplanted to the field until it matures. It is grown in warm climates with rich, well-drained soil. About 4.2 million hectares of tobacco were under cultivation worldwide in 2000, yielding over seven million tonnes of tobacco.

<span class="mw-page-title-main">Curing of tobacco</span>

In nearly all instances where tobacco is to be used for smoking or chewing, it is necessary to cure the tobacco directly after it's harvested. Tobacco curing is also known as color curing, because tobacco leaves are cured with the intention of changing their color and reducing their chlorophyll content.

<span class="mw-page-title-main">History of tobacco</span>

Tobacco was long used in the early Americas. The arrival of Spain introduced tobacco to the Europeans, and it became a lucrative, heavily traded commodity to support the popular habit of smoking. Following the industrial revolution, cigarettes became hugely popular worldwide. In the mid-20th century, medical research demonstrated severe negative health effects of tobacco smoking including lung and throat cancer, which led to a sharp decline in tobacco use.

Tobacco production in Malawi is one of the nation's largest sources of income. As of 2005, Malawi was the twelfth-largest producer of tobacco leaves and the 7th largest global supporter of tobacco leaves. As of 2010, Malawi was the world's leading producer of burley leaf tobacco. With the decline of tobacco farms in the West, interest in Malawi's low-grade, high-nicotine tobacco has increased. Today, Malawian tobacco is found in blends of nearly every cigarette smoked in industrialized nations including the popular and ubiquitous Camel and Marlboro brands. It is the world's most tobacco dependent economy. In 2013 Malawi produced about 133,000 tonnes of tobacco leaf, a reduction from a maximum of 208,000 tonnes in 2009 and although annual production was maintained at similar levels in 2014 and 2015, prices fell steadily from 2013 to 2017, in part because of weakening world demand but also because of declining quality.

A heated tobacco product (HTP) is a tobacco product that heats the tobacco at a lower temperature than conventional cigarettes. These products contain nicotine, which is a highly addictive chemical. The heat generates an aerosol or smoke to be inhaled from the tobacco, which contains nicotine and other chemicals. HTPs may also contain additives not found in tobacco, including flavoring chemicals. HTPs generally heat tobacco to temperatures under 600 °C (1100 °F), a lower temperature than conventional cigarettes. HTPs use embedded or external heat sources, heated sealed chambers, or product-specific customized cigarettes. Whereas e-cigarettes are electronic devices that vaporize a liquid containing nicotine, HTPs usually use tobacco in leaf or some other solid form, although there are some hybrid products that can use both solid tobacco and e-liquids. There are various types of HTPs. The two most common designs are those that use an electric battery to heat tobacco leaf and those that use a carbon ember that is lit and then heats the tobacco. There are similar devices that heat cannabis instead of tobacco.
