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.
Tobacco smoking is the practice of burning tobacco and ingesting the resulting smoke. 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.
A hookah, shisha, or waterpipe is a single- or multi-stemmed instrument for heating or vaporizing and then smoking either tobacco, flavored tobacco, or sometimes cannabis, hashish and opium. The smoke is passed through a water basin—often glass-based—before inhalation.
Smoking bans, or smoke-free laws, are public policies, including criminal laws and occupational safety and health regulations, that prohibit tobacco smoking in certain spaces. The spaces most commonly affected by smoking bans are indoor workplaces and buildings open to the public such as restaurants, bars, office buildings, schools, retail stores, hospitals, libraries, transport facilities, and government buildings, in addition to public transport vehicles such as aircraft, buses, watercraft, and trains. However, laws may also prohibit smoking in outdoor areas such as parks, beaches, pedestrian plazas, college and hospital campuses, and within a certain distance from the entrance to a building, and in some cases, private vehicles and multi-unit residences.
Passive smoking is the inhalation of tobacco smoke, called passive smoke, secondhand smoke (SHS) or environmental tobacco smoke (ETS), by individuals other than the active smoker. It occurs when tobacco smoke diffuses into the surrounding atmosphere as an aerosol pollutant, which leads to its inhalation by nearby bystanders within the same environment. Exposure to secondhand tobacco smoke causes many of the same diseases caused by active smoking, although to a lower prevalence due to the reduced concentration of smoke that enters the airway.
Nicotiana rustica, commonly known as Aztec tobacco or strong tobacco, is a rainforest plant in the family Solanaceae native to South America. It is a very potent variety of tobacco, containing up to nine times more nicotine than common species of Nicotiana such as Nicotiana tabacum. More specifically, N. rustica leaves have a nicotine content as high as 9%, whereas N. tabacum leaves contain about 1 to 3%. The high concentration of nicotine in its leaves makes it useful for producing pesticides, and it has a wide variety of uses specific to cultures around the world. However, N. rustica is no longer cultivated in North America, as N. tabacum has replaced it.
Tobacco products, especially when smoked or used orally, have negative effects on human health. Researchers have addressed concerns about these effects for a long time. They have focused primarily on cigarette smoking.
Cẩm Phả is a city of Quảng Ninh Province in the north-east region of Vietnam. It is an important coal exporting port of Vietnam. As of 2019, the city had a population of 190,232. The city covers an area of 486 km2. The city was promoted from Cẩm Phả District by February 2012. Cẩm Phả was the site of one of the biggest coal mines in south of Asia which has been exploited for almost a century. The coal mine featured on a special commemorative Vietnam stamp in March 1959. Coal still forms the basis of Cẩm Phả's local economy, with other industries including quarrying, lime production, port, agriculture, forestry and fisheries.
Prevalence of tobacco use is reported by the World Health Organization (WHO), which focuses on cigarette smoking due to reported data limitations. Smoking has therefore been studied more extensively than any other form of consumption.
An electronic cigarette (e-cigarette) or vape is a device that simulates tobacco smoking. It consists of an atomizer, a power source such as a battery, and a container such as a cartridge or tank. Instead of smoke, the user inhales vapor. As such, using an e-cigarette is often called "vaping". The atomizer is a heating element that vaporizes a liquid solution called e-liquid, which quickly cools into an aerosol of tiny droplets, vapor and air. E-cigarettes are activated by taking a puff or pressing a button. Some look like traditional cigarettes, and most kinds are reusable. The vapor mainly comprises propylene glycol and/or glycerin, usually with nicotine and flavoring. Its exact composition varies, and depends on several things including user behavior.
Third-hand smoke is contamination by tobacco smoke that lingers following the extinguishing of a cigarette, cigar, or other combustible tobacco product. First-hand smoke refers to what is inhaled into the smoker's own lungs, while second-hand smoke is a mixture of exhaled smoke and other substances leaving the smoldering end of the cigarette that enters the atmosphere and can be inhaled by others. Third-hand smoke or "THS" is a neologism coined by a research team from the Dana–Farber/Harvard Cancer Center, where "third-hand" is a reference to the smoking residue on surfaces after "second-hand smoke" has cleared out.
Smoking is a practice in which a substance is combusted and the resulting smoke is typically inhaled to be tasted and absorbed into the bloodstream of a person. Most commonly, the substance used is the dried leaves of the tobacco plant, which have been rolled with a small rectangle of paper into an elongated cylinder called a cigarette. Other forms of smoking include the use of a smoking pipe or a bong.

Tobacco has a long cultural, economic, and social impact on the United States. Tobacco cultivation in Jamestown, Virginia, in 1610 lead to the expansion of British colonialism in the Southern United States. As the demand for Tobacco grew in Europe, further colonization in British America and Tobacco production saw a parallel increase. Tobacco use became normalized in American society and was heavily consumed before and after American independence.
Tobacco smoking during pregnancy causes many detrimental effects on health and reproduction, in addition to the general health effects of tobacco. A number of studies have shown that tobacco use is a significant factor in miscarriages among pregnant smokers, and that it contributes to a number of other threats to the health of the foetus.
Smoking in Singapore is subjected to restrictions enacted through various legislations such as the Smoking Act, which was first enacted in 1970.
Smoking in South Korea has decreased overall for both men and women in the past decades. However, a high prevalence of tobacco use is still observed, especially with the rise of novel tobacco products such as e-cigarettes and heat-not-burn tobacco products. There are socioeconomic inequalities in smoking prevalence according to gender, income, education, and occupational class. Advocates call for measures to reduce the smoking rates and address smoking inequalities using a combination of monitoring and tobacco control policies. These measures include significant price hikes, mandatory warning photos on cigarette packs, advertising bans, financial incentives, medical help for quitting, and complete smoking bans in public places.
Tobacco smoking in the Philippines affects a sizable minority of the population. According to the 2015 Global Adult Tobacco Survey (GATS) conducted under the auspices of the Philippines' Department of Health, Philippine Statistics Authority, the World Health Organization, and the United States Centers for Disease Control and Prevention, 23.8 percent of the adult population were "current tobacco smokers". This figures represented 16.6 million of 69 million adult Filipinos.
