Overview

Dipping tobacco (also known as American moist snuff or spit tobacco) is a form of smokeless tobacco. It is commonly referred to as dip while the act of using it is known as dipping, having a dip, or packing a lip.

Usage

Dipping tobacco, sometimes called "chew," is commonly confused with chewing tobacco. Rather than chewing on tobacco, dipping consists of placing a small clump of tobacco between the lower or upper lip and gums. The dip rests on the inside lining of the mouth for approximately 20-30 minutes as saliva carries nicotine to the inferior or superior labial arteries.

While dipping, users often produce excess saliva, which is typically spat out. Swallowing this excess saliva can cause irritation to the oesophagus, nausea, and vomiting, though some long-time users can swallow this saliva with no unusual effects.

Dipping is often seen as a way of experiencing the effects of nicotine without inhaling smoke into one's lungs.

Cut sizes

The difference between cut sizes are shown in the length of the individual strands of tobacco. The common cut types are:

Dong Cut - Thin strands of tobacco, typically .7 cm long.
Mid Cut - Small granules, approximately .1 cm cubed.
Fine Cut - Very small granules, slightly larger than a grain of sand.
Pouches - Very finely cut and wrapped in a small envelopes.

Surface area and absorption

Many smokeless tobacco users have preferences in texture and nicotine absorption rates. The finer cut the tobacco is, the greater its surface area, which correlates with increased nicotine absorption. Additionally, the amount of moisture in dipping tobacco can be affected by cut size, with finer cuts retaining more moisture.

Health issues

Cancer dangers

Dipping tobacco has been shown to cause various types of cancer, including oral cancer, esophageal cancer, and pancreatic cancer. Most researchers emphasize that while smokeless tobacco may be a "less harmful" alternative to smoking, as it causes fewer fatalities, it is not a "safe" alternative to smoking.^[1] One recent study indicated that smokeless tobacco users are exposed to more NNK, a carcinogen, than cigarette smokers.^[2]

Cardiovascular effects

Studies are inconclusive as to how significantly smokeless tobacco affects users' cardiovascular systems. 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."^[3] Other studies also indicate that smokeless tobacco related cardiovascular risks are lower than that of smoked tobacco.^[4]^[5] One study states that smokeless tobacco use has a "modest effect on cardiovascular risk factors in young physically fit men."^[6]

However, it is important to note that one Indian study from the state of Rajasthan states, "There is a significantly greater prevalence of multiple cardiovascular risk factors [sic] 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."^[7]

Due to contrasting results in studies, many conclude that further research should be done on the cardiovascular risks of smokeless tobacco.^[8]^[9]

Addiction potential

Smokeless tobacco contains nicotine, which is its primary addictive agent.

According to European Union policy, Scandinavian or some American smokeless tobaccos are at least 90% less hazardous than cigarette smoking.^[10] However, dipping tobacco is still addictive.

Warning labels

The following three warning labels must be rotated on all tins of smokeless tobacco sold in the US:

WARNING: This product may cause mouth cancer.
WARNING: This product may cause gum disease and tooth loss.
WARNING: This product is not a safe alternative to smoking.

Smokeless tobacco companies

Connecticut-based UST Inc. held 62.5 percent of the market as of the third quarter of 2006, according to Morningstar investment research firm. The company's brands include Copenhagen, Skoal, Husky, and Red Seal. The next two largest entities are the Conwood subsidiary of Reynolds American Inc., and Swedish Match. In 2006, smokeless and "spit-less" tobacco products were test-marketed by Altria Group Inc. (formerly Phillip Morris Companies) and R.J. Reynolds Tobacco Company, the former named Taboka and the latter under the brand name Camel Snus^[11].

 ==Usage==
-Dip is sometimes called "chew"; because of this, it is commonly confused with [[chewing tobacco]]. Instead of literally chewing on tobacco, a small clump of dip is 'pinched' out of the tin, and placed between the lower or upper lip and gums. The dip rests on the inside lining of the mouth for approximately 20-30 minutes--ultimately the duration of a dip is determined by the user--where [[saliva]] carries [[nicotine]] to the [[inferior labial|inferior]] or [[superior labial]] arteries.

-Dip tobacco users often produce excess saliva while dipping.  This is typically spat onto the ground, in a bottle, etc. Swallowing can cause irritation to the [[oesophagus]], nausea, and vomiting-- however, some (long-time) users can swallow the tobacco-caused saliva with no unusual effects. 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 constantly using both hands during work (which doesn't provide opportunities for [[Cigarette|cigarette smoking]]).

 ==Cut sizes==
 The difference between cut sizes are shown in the length of the individual strands of tobacco.
+The common cut types are:
-===Types===
+*Dong Cut - Thin strands of tobacco, typically .7 cm long.
-*Dong Cut - Long cut comes in thin strands of tobacco around .7 cm long
+*Mid Cut  - Small granules, approximately .1 cm cubed.
-*Mid Cut  - Mid-cut is comparable to small granules about .1 cm cubed.
+*Fine Cut - Very small granules, slightly larger than a grain of sand.
-*Fine Cut - Fine cut comes in granules slightly larger than a grain of sand.
+*Pouches - Very finely cut and wrapped in a small envelopes.
-*Pouches - Pouches are fine cut wrapped in a small tea bag like envelope .
 ===Surface area and absorption===
-Many smokeless tobacco users have preferences in texture and nicotine absorption rates. The finer cut the tobacco is, the tobacco will have more surface area; as the surface area in the tobacco increases, the rate of absorption is slightly increased, which some users prefer. In addition, the amount of moisture in dipping tobacco can be affected by cut size as well; moisture is easier to maintain the finer cut the tobacco is.

Additionally, the amount of moisture in dipping tobacco can be affected by cut size, with finer cuts retaining more moisture.
-===Ease of use===
-While the differences between fine, long, and mid-cut tobaccos vary, so does the ease of use. The more finely cut the tobacco the less manageable it becomes than that of long/mid-cuts and will tend to fall out of a person's fingers. Longer-cut tobacco  is the most manageable and tends to cling together between the fingers.
 ==Health issues==
 ===Cancer dangers===
-Studies have shown that dipping tobacco has a relatively low risk for cancer, but some studies give conflicting results. One, done in 2004, shows that tobacco-specific [[nitrosamine]] (TSNA) levels were much higher in American dipping tobacco than those of Swedish products.<ref>[http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&dopt=Abstract&list_uids=15470264 Smokeless tobacco and oral cancer: a review of the risks and determinants.] ''[[PubMed]].''

-Cancer, however, is not frequently experienced as a consequence in [[Sweden]], where smokeless tobacco use is well-established. It should be noted, however, that Swedish moist [[Snuff (tobacco)|snuff]] ("[[Snus]]") utilizes a different manufacturing process that is speculated to reduce the amount of harmful chemicals delivered to the smokeless tobacco user, specifically by minimizing [[nitrosamine]] content.<ref>[http://www.tobaccoprogram.org/pdf/TC12349.pdf Effect of smokeless tobacco (snus) on smoking and public health in Sweden]</ref>

-According to one study, only a "handful of websites" contain accurate information on the hazards of smokeless tobacco.  1/3 of websites relating to smokeless tobacco "explicitly" claim that smokeless tobacco is comparable to, or worse than, cigarettes.  The conclusion reads:
-:"Through these websites, and presumably other information provided by the same government, advocacy, and educational organizations, ST [smokeless tobacco] users are told, in effect, that they might as well switch to smoking if they like it a bit more.

-===Additives===
-There are few reports confirming exactly what additives are in smokeless tobacco, and it's very likely that brands vary in what and how much of each additive they use.  One popular, and currently unsubstantiated rumour, is that glass or fiberglass is mixed into each tin to cause abrasion to the lip, resulting in higher and faster nicotine absorption.  There is no evidence that this rumour is true, as there are no cited studies referenced in material that spreads this information.
