Fusarium affine is a fungal plant pathogen affecting tobacco.
A tobacco pipe, often called simply a pipe, is a device specifically made to smoke tobacco. It comprises a chamber for the tobacco from which a thin hollow stem (shank) emerges, ending in a mouthpiece. Pipes can range from very simple machine-made briar models to highly prized hand-made artisanal implements made by renowned pipemakers, which are often very expensive collector's items. Pipe smoking is the oldest known traditional form of tobacco smoking.
Tobacco is the common name of several plants in the Nicotiana genus and the Solanaceae (nightshade) family, and the general term for any product prepared from the cured leaves of the tobacco plant. More than 70 species of tobacco are known, but the chief commercial crop is N. tabacum. The more potent variant N. rustica is also used around the world.
Nicotine is a chiral alkaloid that is naturally produced in the nightshade family of plants and is widely used recreationally as a stimulant and anxiolytic. As a pharmaceutical drug, it is used for smoking cessation to relieve withdrawal symptoms. Nicotine acts as a receptor agonist at most nicotinic acetylcholine receptors (nAChRs), except at two nicotinic receptor subunits where it acts as a receptor antagonist.
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 best 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.
A cigarette is a narrow cylinder containing psychoactive material, typically 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; the resulting smoke is orally inhaled via the opposite end. 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 and cause cancer, chronic obstructive pulmonary disease, heart disease, and other health problems.
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. According to the WHO Framework Convention on Tobacco Control “tobacco industry” means tobacco manufacturers, wholesale distributors and importers of tobacco products; The treaty provides its 181 member states the duty of "In setting and implementing their public health policies with respect to tobacco control, Parties shall act to protect these policies from commercial and other vested interests of the tobacco industry in accordance with national law."
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.
A hookah, also known as the qalyān or shisha, is a single- or multi-stemmed instrument for heating or vaporizing and then smoking either tobacco, flavored tobacco, or sometimes cannabis, hashish, and in the past opium. The smoke is passed through a water basin—often glass-based—before inhalation.
British American Tobacco plc (BAT) is a British multinational company that manufactures and sells cigarettes, tobacco and other nicotine products. The company, established in 1902, is headquartered in London, England. As of 2019, it is the largest tobacco company in the world based on net sales.
Imperial Brands plc, formerly Imperial Tobacco Group plc, is a British multinational tobacco and logistics company headquartered in Bristol, England. It is the world's fourth-largest international cigarette company measured by market share after Philip Morris International, British American Tobacco, and Japan Tobacco, and the world's largest producer of fine-cut tobacco and tobacco papers.
Snus is a moist powder smokeless tobacco product originating from a variant of dry snuff in early 18th-century Sweden. It is placed inside the lip for extended periods, as in 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.
Passive smoking is the inhalation of smoke, called secondhand smoke (SHS), or environmental tobacco smoke (ETS), by persons other than the intended "active" smoker. It occurs when tobacco smoke enters an environment, causing its inhalation by people within that environment. Exposure to secondhand tobacco smoke causes disease, disability, and death. The health risks of secondhand 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.
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 and teeth, and then 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 spat.
Dipping tobacco is a type of finely ground or shredded, moistened smokeless tobacco product. It is commonly and idiomatically known by the term—most often as ‘’’dip’’’. It is used by placing a pinch, or "dip" of tobacco between the lip and the gum. The act of using it is called dipping. Dip is colloquially called "chaw", "snuff", "rub", or "fresh leaf" among other terms; because of this, it is sometimes confused with other tobacco products—namely nasal/dry snuff. Typically, before dipping, the act of "packing" is performed, where the user places the "can" in between the thumb and middle finger, then flicks the index finger onto the lid of the can.
Snuff is a smokeless tobacco made from ground or pulverised tobacco leaves. It is inhaled or "snuffed" into the nasal cavity, delivering a swift hit of nicotine and a lasting flavoured scent. Traditionally, it is sniffed or inhaled lightly after a pinch of snuff is either placed onto the back surface of the hand, held pinched between thumb and index finger, or held by a specially made "snuffing" device.
The smoking age is the minimum legal age required to purchase or use tobacco products. Most countries have laws that forbid sale of tobacco products to persons younger than certain ages, usually the age of majority.
An electronic cigarette is an electronic 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 atomizes a liquid solution called e-liquid. E-cigarettes are activated by taking a puff or pressing a button. Some look like traditional cigarettes, and most versions are reusable.
Smoking is a practice in which a substance is burned and the resulting smoke is 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.
Tobacco has a long history in the United States.
A heated tobacco product (HTP) is a product that consists of a tobacco-containing substance and a battery-powered heating system. The heat generates an aerosol to be inhaled from the tobacco, which contains nicotine, smoke, tar, and other chemicals and particles. HTPs also contain additives not found in tobacco, and are frequently flavoured. Tobacco leaves are heated at approximately 250–350 °C (500 °F), a lower temperature than traditional cigarettes. To deliver nicotine from tobacco leaves, HTPs use embedded or external heat sources, heated sealed chambers, or product-specific customized cigarettes. Although HTPs are not electronic cigarettes, hybrids between the two can use both tobacco and e-liquids. There are various types of HTPs and many similar devices that use cannabis instead of tobacco.
