The cigarette is ignited at one end, causing it to smolder, and the resulting smoke is orally inhaled via the opposite end. Cigarette smoking is the most common method of tobacco consumption.<ref name=":1" /> The term ''cigarette'' refers to a tobacco cigarette, but the word is sometimes used to refer to other substances, such as a cannabis cigarette or a herbal cigarette. A cigarette is distinguished from a cigar by its usually smaller size, use of processed leaf, different smoking method, and paper wrapping, which is typically white.

Deaths from smoking cigarettes are caused by diseases such as cancer, chronic obstructive pulmonary disease (COPD), heart disease, birth defects, and other health problems relating to nearly every organ of the body. Most modern cigarettes are filtered, but this does not make the smoke inhaled from them contain fewer carcinogens or harmful chemicals. Nicotine, the psychoactive drug in tobacco, makes cigarettes highly addictive. About half of cigarette smokers die of tobacco-related disease and lose on average 14 years of life. Every year, cigarette smoking causes more than 8 million deaths worldwide; more than 1.3 million of these are non-smokers dying as a result of exposure to secondhand smoke.<ref name=":1">{{Cite web |title=Tobacco |url=https://www.who.int/news-room/fact-sheets/detail/tobacco |archive-url=https://web.archive.org/web/20210709165139/https://www.who.int/news-room/fact-sheets/detail/tobacco |archive-date=2021-07-09 |access-date=2025-11-26 |website=World Health Organization |language=en-US}}</ref> These harmful effects have led to legislation that has prohibited smoking in many workplaces and public areas, regulated marketing and purchasing age of tobacco, and levied taxes to discourage cigarette use.[[File:2015 E-papieros mod 01.JPG|thumb|An electronic cigarette]]In the 21st century, electronic cigarettes (also called ''e-cigarettes'' or ''vapes'') were developed, whereby a substance contained within the device (typically a liquid solution containing nicotine) is vaporized by a battery-powered heating element as opposed to being burned.

The earliest forms of cigarettes were similar to their predecessor, the cigar. Cigarettes appear to have had antecedents in Mexico and Central America around the 9th century in the form of reeds and smoking tubes. The Maya, and later the Aztecs, smoked tobacco and other psychoactive drugs in religious rituals and frequently depicted priests and deities smoking on pottery and temple engravings. The cigarette and the cigar were the most common methods of smoking in the Caribbean, Mexico, and Central and South America until recent times.<ref>{{Cite book |last1=Gilman |first1=Sander L. |url=https://books.google.com/books?id=mM5bYb_uVcwC |title=Smoke: A Global History of Smoking |last2=Zhou |first2=Xun |date=2004 |publisher=Reaktion Books |isbn=978-1-86189-200-3 |pages=30–37 |language=en}}</ref>

The North American, Central American, and South American cigarette used various plant wrappers; when it was brought back to Spain, maize wrappers were introduced, and by the 17th century, fine paper.

Initially, not all cigarette smokers inhaled the smoke produced by cigarettes due to its high alkalinity levels. Starting in the 1930s, the tobacco industry began to conduct advertising campaigns encouraging the inhaling of cigarette smoke.<ref>{{Cite web |title=Collection: Do you inhale? |url=https://tobacco.stanford.edu/cigarettes/for-your-health/do-you-inhale/# |access-date=2024-02-23 |website=Stanford Research into the Impact of Tobacco Advertising |publisher=Stanford University}}</ref> However, Helmuth von Moltke noticed in the 1830s that Ottomans (and he himself) inhaled the Turkish tobacco and Latakia from their pipes<ref>{{Cite news |last=von Molke |first=Helmuth Graf |title=Unter dem Halbmond - Kapitel 30 |url=http://gutenberg.spiegel.de/buch/3038/30 |archive-url=https://web.archive.org/web/20120119053202/http://gutenberg.spiegel.de/buch/3038/30 |archive-date=2012-01-19 |access-date=2025-11-26 |work=SPIEGEL ONLINE}}</ref> (both are initially sun-cured, acidic leaf varieties).

The cigarette has evolved much since its conception; for example, thin bands that travel transverse to the "axis of smoking" (thus forming circles along the length of the cigarette) are alternate sections of thin and thick paper to facilitate effective burning when being drawn, and retard burning when at rest. Synthetic particulate filters may remove some tar before it reaches the smoker.

The "holy grail" for cigarette companies has been a cancer-free cigarette. The closest historical attempt was produced by scientist James Mold. Under the name "Project TAME", he produced the XA cigarette.

===United States=== One entrepreneur who was quick to spot the advantages of machine-made cigarettes was James Buchanan Duke. Previously a producer of smoking tobacco only, his firm, W. Duke & Sons & Co., entered the cigarette industry in the early 1880s. After installing two Bonsack machines, Duke spent heavily on advertising and sales promotion, and by 1889 his was the largest cigarette manufacturer in the country. The new Bonsack machines were of decisive importance in the rapid, cheap manufacture of all tobacco products but one. Cigars needed slow, laborious hand rolling and were produced in hundreds of small workshops, especially in New York City. In 1890 Duke and the other four major cigarette companies combined to form the American Tobacco Company, a firm that dominated the market and used aggressive tactics on hundreds of small competitors until they sold out to the firm. It was also called the "Tobacco Trust". The trust soon expanded its operations to include cigars, smoking, chewing tobacco and snuff. Among the companies drawn into this organization were the plug manufacturers Liggett & Myers and R. J. Reynolds Tobacco Company, which at the time produced twist and flat plug, and P. Lorillard, an old-line manufacturer of snuff. By 1910 the trust produced 86% of all cigarettes produced in the United States, and 75% to 95% of other forms, but only 14% of cigars produced in the country.<ref>Richard B. Tennant, "The Cigarette Industry" in ''The Structure of American Industry,'' edited by Walter Adams (1961) pp 357-392, at pp 358-362.</ref>

At the start of the 20th century, the ''per capita'' annual consumption in the U.S. was 54 cigarettes (with fewer than 0.5% of the population smoking more than 100 cigarettes per year), and consumption peaked at 4,259 per capita in 1965. At that time, about 50% of men and 33% of women smoked (defined as smoking more than 100 cigarettes per year).<ref>{{Cite journal |title=Tobacco Use, United States 1990-1999 |journal=Oncology (Williston Park) |volume=13 |issue=12 |date=December 1999}}</ref> By 2000, consumption had fallen to 2,092 per capita, corresponding to about 30% of men and 22% of women smoking more than 100 cigarettes per year, and by 2006 per capita consumption had declined to 1,691,<ref>Tobacco Outlook Report, Economic Research Service, U.S. Dept. of Agriculture</ref> corresponding to about 21% of the population smoking 100 cigarettes or more per year.

Modern cigarettes produced after the 1950s, although composed mainly of shredded tobacco leaf, use a significant quantity of tobacco processing byproducts in the blend. Each cigarette's tobacco blend is made mainly from the leaves of flue-cured brightleaf, burley tobacco, and oriental tobacco. These leaves are selected, processed, and aged prior to blending and filling. The processing of brightleaf and burley tobaccos for tobacco leaf "strips" produces several byproducts such as leaf stems, tobacco dust, and tobacco leaf pieces ("small laminate").<ref name=DEMerrill/> To improve the economics of producing cigarettes, these byproducts are processed separately into forms where they can then be added back into the cigarette blend without a marked change in the cigarette's quality.

A recipe-specified combination of brightleaf, burley-leaf, and oriental-leaf tobacco is mixed with various additives to improve its flavors. Most commercially available cigarettes today contain tobacco that is treated with sugar to counter the harshness of the smoke.

=== Additives === Various additives are combined into shredded tobacco product mixtures, including humectants such as propylene glycol or glycerol, as well as flavoring products and enhancers such as cocoa powder, licorice, tobacco extracts, and various sugars, which are known collectively as "casings".<ref name=":0">{{Cite web |last=Bregman |first=Rutger |date=2024-05-08 |title=Abolish the tobacco industry – no one should be allowed to addict and poison others on an industrial scale |url=https://www.moralambition.org/stories/abolish-the-tobacco-industry |access-date=2025-03-27 |website=www.moralambition.org |language=en}}</ref> The leaf tobacco is then shredded, along with a specified amount of small laminate, expanded tobacco, BL, RL, ES, and IS. A perfume-like flavor/fragrance, called the "topping" or "toppings", which is most often formulated by flavor companies, is then blended into the tobacco mixture to improve the consistency in flavor and taste of the cigarettes associated with a certain brand name.<ref name=DEMerrill/> Additionally, they replace flavors lost due to the repeated wetting and drying used in processing the tobacco. Finally, the tobacco mixture is filled into cigarette tubes and packaged.

A list of 599 cigarette additives, created by five major American cigarette companies, was approved by the Department of Health and Human Services in April 1994. None of these additives is listed as an ingredient on cigarette packs. These chemicals are added for organoleptic purposes, and many boost the addictive properties of cigarettes, especially when burned.<ref>{{Cite journal |last1=Rabinoff |first1=Michael |last2=Caskey |first2=Nicholas |last3=Rissling |first3=Anthony |last4=Park |first4=Candice |date=November 2007 |title=Pharmacological and chemical effects of cigarette additives |journal=American Journal of Public Health |volume=97 |issue=11 |pages=1981–1991 |doi=10.2105/AJPH.2005.078014 |issn=1541-0048 |pmc=2040350 |pmid=17666709}}</ref>

One of the classes of chemicals on the list, ammonia salts, converts bound nicotine molecules in tobacco smoke into free nicotine molecules.<ref name=":0" /> This process, known as freebasing, could potentially increase the effect of nicotine on the smoker, but experimental data suggests that absorption is, in practice, unaffected.<ref>{{cite journal |doi=10.1016/j.fct.2008.02.021 |pmid=18450355 |title=The possible role of ammonia toxicity on the exposure, deposition, retention, and the bioavailability of nicotine during smoking |journal=Food and Chemical Toxicology |volume=46 |issue=6 |pages=1863–81 |year=2008 |last1=Seeman |first1=Jeffrey I. |last2=Carchman |first2=Richard A. }}</ref>

===Cigarette tube=== {{Main|Cigarette tube}} Cigarette tubes are prerolled cigarette paper usually with an acetate or paper filter at the end. They have an appearance similar to a finished cigarette, but do not contain any tobacco or smoking material inside, as the consumer is intended to fill the tube themself. They may vary in length from regular (70&nbsp;mm) to king size (84&nbsp;mm) as well as 100s (100&nbsp;mm) and 120s (120&nbsp;mm).<ref name="ref1058918916">{{cite web|url=http://www.wikihow.com/Roll-Your-Own-Filter-Cigarettes|title=How to Roll Your Own Filter Cigarettes: 6 Steps (with Pictures)|work=wikiHow |publisher=wikihow.com|access-date=February 14, 2014|archive-url=https://web.archive.org/web/20140222231725/http://www.wikihow.com/Roll-Your-Own-Filter-Cigarettes|archive-date=February 22, 2014}}{{self-published source|date=March 2017}}</ref>{{self-published inline|date=March 2017}}

Cigarette tubes are usually filled with a cigarette injector (also known as a shooter). Cone-shaped cigarette tubes, known as cones, can be filled using a packing stick or straw because of their shape. Cone smoking is popular because as the cigarette burns, it tends to get stronger and stronger. This is because the cone shape allows more tobacco to be burned at the beginning than the end, allowing for an even flavor.<ref name="ref-653500596">{{cite web|url=http://www.ryomagazine.com/july/filters.htm|title=Review: Zig-Zag Filtered Tubes|work=Roll Your Own Magazine|access-date=February 14, 2014|archive-date=October 6, 2014|archive-url=https://web.archive.org/web/20141006032800/http://www.ryomagazine.com/july/filters.htm|url-status=live}}</ref><ref>{{Cite web |title=Review: Zig-Zag Filtered Tubes |url=http://www.ryomagazine.com/july/filters.htm |archive-url=https://web.archive.org/web/20141006032800/http://www.ryomagazine.com/july/filters.htm |archive-date=2014-10-06 |access-date=2025-11-26 |website=www.ryomagazine.com}}</ref>

=== Cigarette filter === {{Main|Cigarette filter}} A cigarette filter or filter tip is a component of a cigarette. Filters are typically made from cellulose acetate fibre. Most factory-made cigarettes are equipped with a filter; those who roll their own can buy them separately. Filters can reduce the presence of some substances, such as tar, in cigarette smoke, but do not actually make them any safer to smoke.

=== Cigarette butt === {{See also|Ashtray|Cigarette pack#Features}} thumb|right|Discarded cigarette butts

In North America, the common name for the remains of a cigarette after smoking is a ''cigarette butt''. In Britain, it is also called a ''dog-end'' or a ''fag end''.<ref>The Nelson Contemporary English Dictionary - Page 187, W. T.

=== Secondhand smoke === Secondhand smoke is a mixture of smoke from the burning end of a cigarette and the smoke exhaled from the lungs of smokers.

=== Smoking restrictions === {{further|List of smoking bans}} Many governments impose restrictions on smoking tobacco, especially in public areas. The primary justification has been the negative health effects of secondhand smoke.<ref name=second>{{usurped|1=[https://web.archive.org/web/20050906213831/http://www.who.int/tobacco/framework/WHO_FCTC_english.pdf WHO Framework Convention on Tobacco Control]}}; First international treaty on public health, adopted by 192 countries and signed by 168. Its Article 8.1 states, "Parties recognize that scientific evidence has unequivocally established that exposure to tobacco causes death, disease and disability."</ref> Laws vary by country and locality. Nearly all countries have laws restricting places where people can smoke in public, and over 40 countries have comprehensive smoke-free laws that prohibit smoking in virtually all public venues.

=== Smoking age === {{main|Smoking age}}

In the United States, the age to buy tobacco products is 21 in all states as of 2020. Similar laws exist in many other countries. In Canada, most of the provinces require smokers to be 19 years of age to purchase cigarettes (except for Quebec and the prairie provinces, where the age is 18). However, the minimum age only concerns the purchase of tobacco, not use. Alberta, however, does have a law which prohibits the possession or use of tobacco products by all persons under 18, punishable by a $100 fine. Australia, New Zealand, Poland, and Pakistan have a nationwide ban on the selling of all tobacco products to people under the age of 18.

[[File:Tabak-Trafik 12.2006.jpg|right|thumb|''Tabak-Trafik'' in Vienna. Since January 1, 2007, all cigarette machines in Austria must attempt to verify a customer's age by requiring the insertion of a debit card or mobile phone verification.]]

Since October 1, 2007, it has been illegal for retailers to sell tobacco in all forms to people under the age of 18 in three of the UK's four constituent countries (England, Wales, Northern Ireland, and Scotland), increased from 16. It is also illegal to sell lighters, rolling papers, and all other tobacco-associated items to people under 18. It is not illegal for people under 18 to buy or smoke tobacco, it is only illegal for a retailer to sell a tobacco-associated item to them. The age increase from 16 to 18 came into force in Northern Ireland on September 1, 2008. In the Republic of Ireland, bans on the sale of smaller 10-packs and confectionery that resembles tobacco products (candy cigarettes) came into force on May 31, 2007, in a bid to cut underaged smoking. In October 2023, Prime Minister Rishi Sunak proposed a ban on sales of cigarettes to anyone born after 2008.<ref>{{Cite web |date=2023-10-04 |title=Prime Minister to create 'smokefree generation' by ending cigarette sales to those born on or after 1 January 2009 |url=https://www.gov.uk/government/news/prime-minister-to-create-smokefree-generation-by-ending-cigarette-sales-to-those-born-on-or-after-1-january-2009 |access-date=2025-11-26 |website=GOV.UK |language=en}}</ref>

Most countries in the world have a legal vending age of 18. In North Macedonia, Italy, Malta, Austria, Luxembourg, and Belgium, the age for legal vending is 16. Since January 1, 2007, all cigarette machines in public places in Germany must attempt to verify a customer's age by requiring the insertion of a debit card.

Japan is one of the highest tobacco-consuming nations, and requires purchasers to be 20 years of age. Since July 2008, Japan has enforced this age limit at cigarette vending machines through use of the Taspo smart card. In other countries, such as Egypt, it is legal to use and purchase tobacco products regardless of age.{{Citation needed|date=August 2011}} Germany raised the purchase age from 16 to 18 on September 1, 2007.

Some police departments in the United States occasionally send an underaged teenager into a store where cigarettes are sold, and have the teen attempt to purchase cigarettes, with their own or no ID.

Cigarette sales are a significant source of tax revenue in many countries. This fact has historically been an impediment for health groups seeking to discourage cigarette smoking, since governments seek to maximize tax revenues. Furthermore, some countries have made cigarettes a state monopoly, which has the same effect on the attitude of government officials outside the health field.<ref>{{Cite news |url=https://www.washingtonpost.com/wp-srv/national/longterm/tobacco/stories/asia.htm |title=U.S. Aided Cigarette Firms in Conquests Across Asia |work=Washingtonpost.com |date=November 17, 1996 |access-date=November 13, 2009 |archive-date=July 4, 2008 |archive-url=https://web.archive.org/web/20080704144106/http://washingtonpost.com/wp-srv/national/longterm/tobacco/stories/asia.htm |url-status=live }}</ref>

=== Warning messages on packaging === {{Main|Tobacco packaging warning messages}}

As a result of tight advertising and marketing prohibitions, tobacco companies view packaging as a vital factor in displaying brand imagery and creating in-store presence at the point of purchase. Market testing shows the influence of this dimension in shifting the consumer's choice when the same product is displayed in alternative packaging. Companies have manipulated a variety of elements on packaging designs to communicate the impression of lower tar content or milder cigarettes, although the actual contents were the same.<ref>"Many smokers are misled by pack design into thinking that cigarettes may be 'safer'," states Melanie Wakefield, et al.

The significant reductions in smoking rates in the United States, United Kingdom, Australia, Brazil, and other countries that implemented strong tobacco control programs{{According to whom|date=December 2019}} have been offset by increasing consumption in low income countries, especially China. The Chinese market now consumes more cigarettes than all other low- and middle-income countries combined.

Other regions are increasingly playing larger roles in the growing global smoking epidemic. The WHO Eastern Mediterranean Region (EMRO) now has the highest growth rate in the cigarette market, with more than a one-third increase in cigarette consumption since 2000. Due to its recent dynamic economic development and continued population growth, Africa presents the greatest risk in terms of future growth in tobacco use.

Within countries, patterns of cigarette consumption also can vary widely.&nbsp;For example, in many of the countries where few women smoke, smoking rates are often high in males (e.g., in Asia). By contrast, in most developed countries, female smoking rates are typically only a few percentage points below those of males. In many high and middle income countries lower socioeconomic status is a strong predictor of smoking.&nbsp;

Smoking rates in the United States have dropped by more than half from 1965 to 2016, falling from 42% to 15.5% of US adults.{{citation needed|date=January 2026}} Australia is cutting their overall smoking consumption faster than most of the developed world, in part due to the landmark Plain Packaging Act, which standardized the appearance of cigarette packs. Other countries have considered similar measures. In New Zealand, a bill has been presented to Parliament which the government's associate health minister said "takes away the last means of promoting tobacco as a desirable product."<ref>{{cite news|url=https://www.nytimes.com/2014/06/12/business/international/australias-graphic-cigarette-pack-warnings-appear-to-work.html|title=Australia's Graphic Cigarette Pack Warnings Appear to Work|first=Michelle|last=Innis|newspaper=The New York Times|date=June 11, 2014|access-date=February 24, 2017|archive-date=December 29, 2017|archive-url=https://web.archive.org/web/20171229113152/https://www.nytimes.com/2014/06/12/business/international/australias-graphic-cigarette-pack-warnings-appear-to-work.html|url-status=live}}</ref> {| class="wikitable" |+Smoking prevalence by sex (ages 15 or older, 2016)<ref>{{Cite web|url=http://apps.who.int/gho/data/view.sdg.3-a-data-reg?lang=en|title=Age-standardized prevalence of current tobacco smoking among persons aged 15 years or older, 2016|date=2018|access-date=July 17, 2019|archive-date=July 30, 2018|archive-url=https://web.archive.org/web/20180730093712/http://apps.who.int/gho/data/view.sdg.3-a-data-reg?lang=en|url-status=live}}</ref> |- ! ! colspan="2" | Percent smoking |- !

The filter design is one of the main differences between light and regular cigarettes, although not all cigarettes contain perforated holes in the filter. In some light cigarettes, the filter is perforated with small holes that theoretically dilute the concentration of tobacco smoke with clean air. In regular cigarettes, the filter does not include these perforations. In ultralight cigarettes, the filter's perforations are larger. The majority of major cigarette manufacturers offer a light, low-tar, or mild cigarette brand. Due to recent U.S. legislation prohibiting the use of these descriptors, tobacco manufacturers are turning to color-coding to allow consumers to differentiate between regular and light brands.<ref name="Koch">Koch 2009</ref>

Research shows that smoking "light" or "low-tar" cigarettes is just as harmful as smoking other cigarettes.<ref name="National">U.S. National 2004</ref><ref name="Benowitz">Benowitz 2005, p. 1</ref><ref>NCI's Smoking 2007, p.7</ref>
