词条 | Dipping tobacco |
释义 |
Dipping tobacco is a type of finely ground or shredded, moistened smokeless tobacco product. It is commonly and idiomatically known by various terms—most often as dip or chew. 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 or sometimes chewing. 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. HistoryDipping 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.[1] Using dry snuff orally eventually evolved into modern day moist snuff, with Copenhagen introduced in 1822, and Skoal introduced in 1934. Most varieties of dipping tobacco are much more recent inventions. Today, moist snuff is available throughout the United States. However, it is typically more popular in rural areas and the South than in large cities.{{Citation needed|date=June 2018}} Dipping tobacco is predominately used by males.{{Citation needed|date=June 2018}} Also, dipping tobacco has a similar presence in Canada. Smokeless tobacco use by professional baseball players was widespread throughout the 19th century until more recent years with the MLB cracking down on tobacco consumption, although a 1999 survey reported that "31 percent of the league's rookies used smokeless tobacco"[2]. According to recent reports from NFL players, many professional footballers chew tobacco in locker rooms, with some teams reporting that up to 75% of players admit to dipping[3]. DescriptionDipping tobacco is packaged in "tins" or "cans", although they are not typically completely metal anymore. Dipping tobacco is also available in "rolls", "logs", or "sleeves", which is a package of 5 tins of tobacco, a similar concept to that of a carton of cigarettes. Ten tin rolls were also available in the past. Another package of dipping tobacco is the "tub", available in only select brands, equivalent to 6, 10, or 12 cans. Before opening the can/tin of tobacco, users typically "pack" the can, similar to how cigarette smokers pack a pack of cigarettes. This is done by placing one's thumb and middle finger on the sides of the can, and then quickly turning the can and flicking the wrist so that one's index finger taps the top of the can. Unlike snus, which is most often placed between the upper lip and gum, moist tobacco users or "dippers" tend to use the lower. Dipping in the upper lip is unusual, though when done, it is colloquially termed an "upper decker" or "top lip dip".{{citation needed|date=March 2013}} The dip rests on the inside lining of the mouth for a period depending upon the user's preference—often 20–40 minutes.{{citation needed|date=October 2015}} Nicotine and other alkaloids found in tobacco are absorbed in saliva sublabially by the inferior or superior labial arteries. Buccal and sublingual absorption may also occur. Also unlike snus, dip often causes the user to produce excess saliva during the act of dipping. This is typically spit onto the ground or in a container, because swallowing the saliva-tobacco mixture can cause irritation to the esophagus and induce nausea and vomiting. A spittoon can be used, but often users will simply use an empty plastic bottle or a "mudjug," a portable spittoon. Smokeless tobacco is sometimes used in the workplace by employees, especially if the employer does not provide many cigarette breaks or if the employee is consistently using both hands during work (which doesn't provide opportunities for cigarette smoking). Smokeless tobacco is popular in many industrial areas where there is a safety risk in having an open flame, such as oil rigs or refineries. Etymology and terminology{{Unreferenced section|date=November 2017}}Dipping tobacco was first popularized and marketed as moist snuff in the 1800s. The term "snuff" in this context is an English cognate of the aforementioned "snus", from Swedish. Dipping tobacco's Scandinavian roots impart a noticeable legacy on modern American brands such as Copenhagen and Skoal (referring to the interlinguistic term skål, which in Norwegian, Danish, Icelandic, Faroese and Swedish roughly translates to "cheers", implying a toast). A user of dipping tobacco will produce an excess amount of saliva which will be disposed of using a "spitter." A spitter can be an empty bottle, cup or commercially produced spittoon. Dipping tobacco use is often accompanied by first drinking a liquid, in some areas known as a primer, catalyst, and rinser. A primer is used to initially salivate the mouth, usually during a meal, in order to prepare the mouth to use smokeless tobacco. This is important because a dry mouth or one full of food could lead to a less enjoyable experience for the user. A catalyst, like a primer, is used to fix the issues of a dry mouth or dry tobacco, however, the dipping tobacco is already currently in the user's lip. A rinser is used when the user is finished with their tobacco, and it is swished around in the user's mouth, similar to mouthwash, to dispose of any excess tobacco juice or particulates. All three liquids are usually water, but any liquid may be used.{{Citation needed|date=November 2017}} Primarily in Texas and other southern US states, terminology is unique. Dip or dips refers to a wad of tobacco, whereas snuff refers to any amount of tobacco greater than a dip. For example, a tobacco user may reach for a dip from their can of snuff. Many areas have no such distinction, and may rarely use the word "snuff". Cut sizesThe difference between cut sizes is the length of the strands of dip.Common cut sizes
Unique cut sizesThe following cuts are either unique to one brand of dipping tobacco or are extremely rare.
FlavoringDipping tobacco is typically flavored. The most common flavors consist of mint, wintergreen, straight and natural, these are typically made by all brands. The list keeps on going with brands such as Skoal, Kayak and Tough Guy, which make many fruit flavours such as grape, cherry, apple, orange, lemon/citrus, peach, and watermelon. Grizzly has modified their wintergreen and mint flavours, selling separate products called "dark mint" and "dark wintergreen". An alcohol-flavored product has been sold by Copenhagen, which released a limited edition "black" flavor, which was made to taste similar to bourbon. Seneca is a tobacco brand that produces a rum flavour. Health issuesEffectsDipping tobacco, like other tobacco products, contains the stimulant nicotine. Effects include increased heart rate, an increase in systolic blood pressure, and an increase in adrenaline.[4] Long-term effectsLong term use results in whitening of the oral mucosa, termed smokeless tobacco keratosis. There is relatively low risk of transformation of this lesion into mouth cancer (sometimes verrucous carcinoma). Dipping tobacco is believed to cause fatal oral cancers, tooth and gum loss. Associated cancers include: tongue cancer, lip cancer, cheek cancer, gum cancer, throat cancer, and cancer in the roof and floor of the mouth.[5] In a comprehensive review of all reports from previous years,{{when?|date=July 2017}} one study noted "The use of moist snuff and chewing tobacco imposes minimal risks for cancers of the oral cavity and other upper respiratory sites, with relative risks ranging from 0.6 to 1.7."[6] A study comparing oral cancer mortality rates of West Virginia (the state with the highest consumption of smokeless tobacco) in the early nineties to the US overall average throughout the years 1950 to 1980 found no apparent increased incidence or mortality. [7] A study, pooling results from 11 studies between 1981 and 2006, found that users of smokeless tobacco are at elevated risk of getting head and neck cancer, particularly oral cavity cancer. [8] Cardiovascular effectsStudies are inconclusive as to how significantly smokeless tobacco affects users' cardiovascular systems, but it has been suggested that it may have less nicotine than cigarettes. One study states that, "Although the evidence is not conclusive, the adverse cardiovascular effects of smokeless tobacco use are less than those caused by smoking but are more than those found in non-users."[9] Other studies also indicate that smokeless tobacco related cardiovascular risks are lower than that of smoked tobacco.[10][11] One study states that smokeless tobacco use has a "positive effect on cardiovascular risk factors in young physically fit men."[12] However, one Indian study from the state of Rajasthan states, "There is a significantly greater prevalence of multiple cardiovascular risk factors obesity, resting tachycardia, hypertension, high total and LDL cholesterol, and low HDL cholesterol, and electrocardiographic changes in tobacco users, chewing or smoking, as compared-to tobacco non-users. Chewing tobacco is associated with similar cardiovascular risk as smoking."[13] Due to contrasting results in studies, many conclude that further research should be done on the cardiovascular risks of smokeless tobacco.[14][15] Addiction potentialSmokeless tobacco contains nicotine, which is addictive thus the primary reinforcing agent.{{Citation needed|date=October 2018}} According to European Union policy advice, Scandinavian or some American smokeless tobaccos (specifically snus) may be up to 90% less hazardous than cigarette smoking.[16] However, the habit is still addictive. Taxation and restriction of smoking is causing more smokeless tobacco use as "substitution." There have been public health debates regarding risk-reduction for smokers and the reconsideration of smokeless tobacco risks. "...There is a substantial body of informed and independent opinion that sees the value of harm reduction strategies based on smokeless tobacco."[17]AdditivesThe amount of nicotine absorbed can be controlled by different cutting of the tobacco, increasing the nicotine concentration and raising the pH of the tobacco by adding various salts.[18] An alkaline pH causes more nicotine to be absorbed, especially the free, unprotonated form, but is irritating to the mucosa. Nicotine itself can also irritate the mucosa. List of brandsThe following is a partial list of brands of dipping tobacco. Other tobacco products, such as chewing tobacco and snus, are excluded.[19]
LegalitySeveral countries have banned the sale (and in some cases the import) of dipping tobacco. Sale of dipping tobacco was banned in South Australia in 1986 and across the country in 1991[20] and in most of the EU nations in 1993.[21] Sweden was exempt from this ban because of the traditionally high usage of snus in that country. Dipping tobacco is also not currently permitted for sale in the UK. It is not yet clear whether this law will be changed when the UK leaves the EU.[22] In the United States, the Family Smoking Prevention and Tobacco Control Act gives the Food and Drug Administration the power to regulate the tobacco industry.[23] This law prohibits the sale of dipping tobacco to anyone under the age of 18, restricts tobacco product advertising and marketing directed to younger audiences, and requires bigger, more prominent warning labels for dipping tobacco products.[24] TaxationIn the United States, the federal government taxes dipping tobacco at {{convert|0.5033|$/lb|$/kg|2}}, equivalent to 3.15¢ per {{convert|1|oz|g|spell=in|adj=on}} package.[25] Excise taxes are also levied at the state level (Pennsylvania being the only exception), and in some instances, at the local level. Sales tax is also applied to the full retail price of dipping tobacco in most jurisdictions. The price of a tin of tobacco can range anywhere from under $1 per tin to more than $8. Price is affected by factors such as brand and especially the varying excise taxes from state to state. See also
