I have no doubt it is bad for health, but so is red meat.

My question is how bad it is. I need some reference and comparisons with other things


Answers:

Chewing tobacco is leaf tobacco that is chewed by placing a wad between the cheek and the teeth and sucking on it. Snuff is finely ground tobacco. People place a pinch of snuff between their cheek and gum or between their lower lip and gum. Chewing tobacco and snuff are called smokeless tobacco.
Advertising and promotion by the tobacco companies implies that using smokeless tobacco is both safe and socially acceptable. That's not true.
There are serious health risksfor all smokeless tobacco users such as damage to the delicate lining of the mouth and throat, which may result in cancer. Users also increase their risk of heart disease and stroke. Chewing tobacco and snuff make the heart work harder by increasing heart rate and blood pressure.
For those who smoke cigarettes and use smokeless tobacco, the risks are highest for developing cancer of the mouth and throat.
Smokeless tobacco also causes bad breath, decrease in taste and smell and increase in saliva flow. Users have to spit often, causing unpleasant situations for those around them.

Chewing tobacco and snuff contain 28 carcinogens (cancer–causing agents). The most harmful carcinogens in smokeless tobacco are the tobacco–specific nitrosamines (TSNAs). They are formed during the growing, curing, fermenting, and aging of tobacco. TSNAs have been detected in some smokeless tobacco products at levels many times higher than levels of other types of nitrosamines that are allowed in foods, such as bacon and beer.

Other cancer–causing substances in smokeless tobacco include N–nitrosamino acids, volatile N–nitrosamines, benzo(a)pyrene, volatile aldehydes, formaldehyde, acetaldehyde, crotonaldehyde, hydrazine, arsenic, nickel, cadmium, benzopyrene, and polonium–210.

All tobacco, including smokeless tobacco, contains nicotine, which is addictive. The amount of nicotine absorbed from smokeless tobacco is 3 to 4 times the amount delivered by a cigarette. Nicotine is absorbed more slowly from smokeless tobacco than from cigarettes, but more nicotine per dose is absorbed from smokeless tobacco than from cigarettes. Also, the nicotine stays in the bloodstream for a longer time.


What cancers are caused by or associated with smokeless tobacco use?

Smokeless tobacco users increase their risk for cancer of the oral cavity. Oral cancer can include cancer of the lip, tongue, cheeks, gums, and the floor and roof of the mouth.

People who use oral snuff for a long time have a much greater risk for cancer of the cheek and gum than people who do not use smokeless tobacco.

The possible increased risk for other types of cancer from smokeless tobacco is being studied.


What are some of the other ways smokeless tobacco can harm users' health?
Some of the other effects of smokeless tobacco use include addiction to nicotine, oral leukoplakia (white mouth lesions that can become cancerous), gum disease, and gum recession (when the gum pulls away from the teeth). Possible increased risks for heart disease, diabetes, and reproductive problems are being studied.

Is smokeless tobacco a good substitute for cigarettes?
In 1986, the Surgeon General concluded that the use of smokeless tobacco "is not a safe substitute for smoking cigarettes. It can cause cancer and a number of noncancerous conditions and can lead to nicotine addiction and dependence." Since 1991, the National Cancer Institute (NCI), a part of the National Institutes of Health, has officially recommended that the public avoid and discontinue the use of all tobacco products, including smokeless tobacco. NCI also recognizes that nitrosamines, found in tobacco products, are not safe at any level. The accumulated scientific evidence does not support changing this position.
