Tobacco Companies Of Japan
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. 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. 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. Etymology The English word ''tobacco'' originates from the Spanish word "tabaco".

Tobacco Smoking
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. 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. Man ...

Little, Brown And Company
Little, Brown and Company is an American publishing company founded in 1837 by Charles Coffin Little and James Brown in Boston. For close to two centuries it has published fiction and nonfiction by American authors. Early lists featured Emily Dickinson's poetry and '' Bartlett's Familiar Quotations''. Since 2006 Little, Brown and Company is a division of the Hachette Book Group. 19th century Little, Brown and Company had its roots in the book selling trade. It was founded in 1837 in Boston by Charles Little and James Brown. They formed the partnership "for the purpose of Publishing, Importing, and Selling Books". It can trace its roots before that to 1784 to a bookshop owned by Ebenezer Battelle on Marlborough Street. They published works of Benjamin Franklin and George Washington and they were specialized in legal publishing and importing titles. For many years, it was the most extensive law publisher in the United States, and also the largest importer of standard English law ...

Harmala Alkaloid
Several alkaloids that function as monoamine oxidase inhibitors (MAOIs) are found in the seeds of '' Peganum harmala'' (also known as '' Harmal'' or ''Syrian Rue''), as well as tobacco leaves including harmine, harmaline, and harmalol, which are members of a group of substances with a similar chemical structure collectively known as ''harmala alkaloids''. These alkaloids are of interest for their use in Amazonian shamanism, where they are derived from other plants. The harmala alkaloid harmine, once known as telepathine and banisterine, is a naturally occurring beta-carboline alkaloid that is structurally related to harmaline, and also found in the vine '' Banisteriopsis caapi''. Tetrahydroharmine is also found in ''B. caapi'' and ''P. harmala''. Dr. Alexander Shulgin has suggested that harmine may be a breakdown product of harmaline. Harmine and harmaline are both a reversible inhibitor of monoamine oxidase A (RIMAs). They can stimulate the central nervous system by inhibi ...

Nicotine
Nicotine is a natural product, naturally produced alkaloid in the nightshade family of plants (most predominantly in tobacco and ''Duboisia hopwoodii'') and is widely used recreational drug use, recreationally as a stimulant and anxiolytic. As a pharmaceutical drug, it is used for smoking cessation to relieve drug withdrawal, 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. Nicotine is also present at Parts-per notation, ppb-concentrations in edible plants in the family Solanaceae, including potatoes, tomatoes, and eggplants, though sources disagree on whether this has any biological significance to human consumers. It functions as an plant defense against herbivory, antiherbivore toxin; consequently, nicotine was widely used as an insectic ...

Alkaloid
Alkaloids are a class of basic, naturally occurring organic compounds that contain at least one nitrogen atom. This group also includes some related compounds with neutral and even weakly acidic properties. Some synthetic compounds of similar structure may also be termed alkaloids. In addition to carbon, hydrogen and nitrogen, alkaloids may also contain oxygen, sulfur and, more rarely, other elements such as chlorine, bromine, and phosphorus.Chemical Encyclopedia: alkaloids xumuk.ru Alkaloids are produced by a large variety of organisms including , , |
Stimulant
Stimulants (also often referred to as psychostimulants or colloquially as uppers) is an overarching term that covers many drugs including those that increase activity of the central nervous system and the body, drugs that are pleasurable and invigorating, or drugs that have sympathomimetic effects. Stimulants are widely used throughout the world as prescription medicines as well as without a prescription (either legally or illicitly) as performance-enhancing or recreational drugs. Among narcotics, stimulants produce a noticeable crash or '' comedown'' at the end of their effects. The most frequently prescribed stimulants as of 2013 were lisdexamfetamine (Vyvanse), methylphenidate (Ritalin), and amphetamine (Adderall). It was estimated in 2015 that the percentage of the world population that had used cocaine during a year was 0.4%. For the category "amphetamines and prescription stimulants" (with "amphetamines" including amphetamine and methamphetamine) the value was 0.7%, an ...

Snus
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. The sale of snus is illegal in all the European Union countries except for Sweden. It is the most common type of tobacco product in Norway (which is not in the EU), and is available in Switzerland as well. Some EU countries like Estonia allow the sale of nicotine pouches, snus-like products that contain nicotine but no tobacco. Snus is also available in the United States. Canada makes it difficult to obtain snus through its high taxes on imported tobacco products. Snus has been seen as an alternative to smoking, vaping, chewing, dipping, and dissolvable and snuff tobacco products. Snus usually ...

Dipping Tobacco
Dipping tobacco is a type of finely ground or shredded, moistened smokeless tobacco product. It is commonly and idiomatically known as "dip". Dipping tobacco is used by placing a pinch, or "dip", of tobacco between the lip and the gum ( sublabial administration). 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. History Dipping tobacco evolved from the use of dry snuff in early American history. Up until the late 1700s, dry snuff was taken nasally, but then early Americans would take snuff orally by chewing the end of a twig until it resembled a brush, and then "dipping" the twig in the snuff and placing it in their mouths until the snuff dissolved. Using dry snuff orally eventually evolved into modern day moist snuff, which Copenhagen introduced in 1822 and then Skoal started producing in 1934. Mo ...

Chewing Tobacco
Chewing tobacco is a type of smokeless tobacco product that is placed between the cheek and lower gum to draw out its flavor. Some users chew it, others do not. It consists of coarsely chopped aged tobacco that is flavored and often sweetened; it is not ground fine like dipping tobacco. Unwanted juices are then spat. Chewing tobacco may be left as loose leaf or compressed into a small rectangular "plug". Nearly all modern chewing tobaccos are produced by a process of leaf curing, cutting, fermentation, and processing, which may include sweetening and flavoring. Historically, many American chewing-tobacco brands popular during the American Civil War era were made with cigar clippings. Chewing tobacco is a source of nicotine. History Chewing is one of the oldest methods of consuming tobacco. Indigenous peoples of the Americas in both North and South America chewed the leaves of the plant long before the arrival of Europeans. The Southern United States was distinctive for ...

Snuff (tobacco)
Snuff is a smokeless tobacco made from finely ground or pulverized tobacco leaves. The Old Snuff House of Fribourg & Treyer at the Sign of the Rasp & Crown, No.34 James's Haymarket, London, S.W., 1720, 1920. Author: George Evens and Fribourg & Treyer. Publisher: Nabu Press, London, England. Reproduced 5 August 2010, It is inhaled or "sniffed" (alternatively sometimes written as "snuffed") into the nasal cavity, delivering a swift hit of nicotine and a lasting flavored scent (especially if flavoring has been blended with the tobacco). 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. Snuff originated in the Americas and was in common use in Europe by the 17th century. Traditional snuff production consists of a lengthy, multi-step process, in tobacco snuff mills. The selected tobacco leaves are first subject to sp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
