Dipping tobacco

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 and sometimes as rub. It is used by placing a lump, pinch, or "dip" of tobacco between the lip and the gum. The act of using it is called dipping. Typically, before dipping, the act of "packing" is performed, where the user places the "can" in between their thumb and middle finger, then flicks their index finger onto the lid of the can. Dip is colloquially called "chew", "snuff", or "chaw" 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.[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. Dipping tobacco is predominately used by males. Also, dipping tobacco has a similar presence in Canada.

Description

Dipping tobacco is packaged in "tins", 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 tins.

Before opening the can/tin of tobacco, users typically "pack" the tin, 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 tin, and then quickly turning the tin and flicking the wrist so that one's index finger taps the top of the tin.

Unlike snus, which is most often placed between the upper lip and gum, dip 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". The dip rests on the inside lining of the mouth for a period depending upon the user's preference—often 20–40 minutes. 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.

Unlike snus, dip often causes the user to produce excess saliva during the act of dipping. This is typically expectorated onto the ground or in a container, because swallowing the saliva-tobacco mixture can cause irritation to the esophagus and induce nausea and vomiting. Spittoons 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

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).

Cut sizes

The difference between cut sizes are the length of the strands of dip.

Common cut sizes

Unique cut sizes

The following cuts are either unique to one brand of dipping tobacco or are extremely rare.

Flavoring

Dipping tobacco is typically flavored. Most common flavors include wintergreen, mint, straight, and natural. Fruit flavors are also available and can include peach, citrus, berry, cherry, apple, and grape. Copenhagen also produces two alcohol-flavored dips, Cope Whiskey Blend and Copenhagen Black (bourbon flavored).

Effects

Dipping 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.[2]

Long-term effects

Long 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.[3]

In a comprehensive review of all reports from previous years, 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."[4] SEER, the Surveillance Epidemiology and End Results program of the National Cancer Institute, noted in 2012 that there were 3.6 cases of oral cancer among 100,000 smokeless tobacco users each year, the same rate seen in non-exposed men.[5]

Cardiovascular effects

Studies 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."[6] Other studies also indicate that smokeless tobacco related cardiovascular risks are lower than that of smoked tobacco.[7][8] One study states that smokeless tobacco use has a "positive effect on cardiovascular risk factors in young physically fit men."[9] 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."[10]

Due to contrasting results in studies, many conclude that further research should be done on the cardiovascular risks of smokeless tobacco.[11][12]

Addiction potential

Smokeless tobacco contains nicotine, which is addictive thus the primary reinforcing agent.

According to European Union policy advice, Scandinavian or some American smokeless tobaccos (specifically snus) may be up to 90% less hazardous than cigarette smoking.[13] 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."[14]

Additives

The 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.[15] 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 brands

The following is a partial list of brands of dipping tobacco. Other tobacco products, such as chewing tobacco and snus, are excluded.[16]

Legality

Several 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[17] and in most of the EU nations in 1993.[18] Sweden was exempt from this ban because of the traditionally high usage of snus in that country.

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.[19] 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.[20]

Taxation

In the United States, the federal government taxes dipping tobacco at $0.5033 per pound or $0.0315 per ounce, tin or pouch.[21] 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.
