What Is Snuff? Dry, Moist and Nasal Snuff Explained

What is snuff? Snuff is finely cut or powdered tobacco that you use without burning it. Depending on the type, you tuck a pinch between your cheek and gum or sniff it into your nose, and the nicotine is absorbed through the lining of the mouth or nose. This guide explains the dry, moist and nasal types, how snuff compares with snus and chewing tobacco, what the National Cancer Institute says about the health risks, how much nicotine it holds and how to quit.

What Is Snuff?

The National Cancer Institute (NCI) starts with the basics: “Smokeless tobacco is tobacco that is not burned.” Among the names it lists are chewing tobacco, oral tobacco, spit tobacco, dip, chew, and snuff. It then defines snuff itself: “Snuff, which is finely cut or powdered tobacco. It may be sold in different scents and flavors. It is packaged moist or dry; most American snuff is moist” (NCI, Smokeless Tobacco and Cancer).

Snuff is sold in several forms. The NCI says it is “available loose, in dissolvable lozenges or strips, or in small pouches similar to tea bags.” People who use it “chew or suck (dip) the tobacco in their mouth and spit out the tobacco juices that build up,” although “spitless” versions have also been developed. Nicotine “is absorbed through the lining of the mouth.”

The NCI also notes that people in many regions, including North America, northern Europe, India and other Asian countries, and parts of Africa, “have a long history of using smokeless tobacco products.” In other words, snuff is not new, and the traditions around it differ widely from place to place.

Moist Snuff, Dry Snuff and Nasal Snuff: How They Differ

Most confusion about snuff comes from the fact that one word covers different products. Here is how the NCI and the medical literature describe them.

The NCI describes the oral method this way: “The user places a pinch or pouch of moist snuff between the cheek and gums or behind the upper or lower lip.” If your snuff comes in tea-bag-style pouches, that is what this describes. For more on snus specifically, read our guide on what snus is and whether it is safer than smoking.

Snuff vs Snus vs Chewing Tobacco

The NCI sorts smokeless tobacco into two main types. The first is chewing tobacco, “available as loose leaves, plugs (bricks), or twists of rope,” with a piece placed “between the cheek and lower lip, typically toward the back of the mouth,” where it is chewed or held in place. The second is snuff.

So the difference is mostly texture and method: chewing tobacco is leaf, plug or twist, while snuff is cut fine or powdered. Snus, in the NCI’s wording, is another name for moist snuff. Products also vary by country, so check the label.

• Snuff: finely cut or powdered; moist or dry; loose, in lozenges or strips, or in pouches.
• Chewing tobacco: loose leaves, plugs or twists, chewed or held between cheek and lip.
• Snus: described by the NCI as another name for moist snuff.

If you want the full comparison of risk between the two big categories, we cover that in is chewing tobacco worse than smoking. For a different product people often confuse with snuff, see snus vs Zyn differences compared. If you are sorting through other products that sound safer than they are, our look at whether clove cigarettes are worse than regular cigarettes makes a similar point.

Health Risks of Snuff: Cancer, Gums and Heart

The NCI is clear on the central point: “There is no safe form of tobacco. At least 28 chemicals in smokeless tobacco have been found to cause cancer.” The most harmful, it says, are tobacco-specific nitrosamines, which form during the growing, curing, fermenting and aging of tobacco. It adds that “the nitrosamine level is directly related to the risk of cancer,” and that other cancer-causing substances include polonium-210 and polycyclic aromatic hydrocarbons.

Cancer

According to the NCI: “Smokeless tobacco causes oral cancer, esophageal cancer, and pancreatic cancer.”

Gums, mouth and heart

The same page says smokeless tobacco “may also cause heart disease, gum disease, and oral lesions other than cancer, such as leukoplakia (precancerous white patches in the mouth).”

What we know and do not know about nasal snuff

Evidence on nasal snuff is thinner, and it is worth being honest about that. A 2003 review in The Journal of Laryngology & Otology notes: “The nicotine contained leads to dependency,” and that “chronic abuse leads to morphological and functional changes in the nasal mucosa.” It also states that although nasal snuff contains potentially carcinogenic substances, “at present, there is no firm evidence, relating the use of nasal snuff to a higher incidence of head and neck or other malignancies” (J Laryngol Otol, 2003).

Read that carefully: absence of firm evidence is not evidence of safety. It is a 2003 review, the research base is small, and the same review confirms dependence. We do not claim nasal snuff is harmless, and we do not claim it causes a specific cancer.

How Much Nicotine Is in Snuff?

Nicotine content is where people most often get misled by claims in either direction. The NCI cites a Centers for Disease Control and Prevention study of the 40 most widely used popular brands of moist snuff, which found that “the amount of nicotine per gram of tobacco ranged from 4.4 milligrams to 25.0 milligrams.” Other studies it lists found moist snuff between 4.7 and 24.3 mg per gram, dry snuff between 10.5 and 24.8 mg per gram, and chewing tobacco between 3.4 and 39.7 mg per gram.

These are amounts per gram of tobacco, not per pinch or per hour, so they cannot be compared directly with a cigarette. The NCI does make a useful comparison on blood levels: “Users of smokeless tobacco and users of cigarettes have comparable levels of nicotine in the blood,” and “the nicotine stays in the blood longer for users of smokeless tobacco than for smokers.” It also notes that blood levels depend on the nicotine in the product, the tobacco cut size and the product’s pH, among other factors.

Put plainly, snuff is a real nicotine addiction. The NCI states that “all tobacco products, including smokeless tobacco, contain nicotine, which is addictive.” There is no reliable multiple like “X times more nicotine than a cigarette,” so this guide does not give one.

How to Quit Snuff

Snuff is not a stepping stone. The NCI says that as long ago as 1986, the advisory committee to the Surgeon General concluded smokeless tobacco “is not a safe substitute for smoking cigarettes. It can cause cancer and a number of noncancerous oral conditions and can lead to nicotine addiction and dependence.” It also states: “There is no scientific evidence that using smokeless tobacco can help a person quit smoking.”

If you use snuff and want to stop, the NCI points to free human help. It lists a Smoking Quitline at 1-877-44U-QUIT (1-877-448-7848), staffed Monday to Friday, 9:00 a.m. to 9:00 p.m. Eastern time within the United States, and a LiveHelp online chat with a cessation counselor. Check the NCI page for current hours.

A practical plan

• Learn your pattern. When do you reach for the tin or pouch: after meals, in the truck, at work? Writing it down shows your triggers.
• Talk to a pharmacist or doctor. Ask what suits you; we are not giving dosing advice here.
• Plan the oral habit. A big part of snuff is the hands-and-mouth routine, so line up something else to do in the same moments.
• Get step-by-step guidance. Our guide on how to quit chewing tobacco and dip covers the withdrawal and routine side in detail, and the complete evidence-based quit smoking guide covers medication and support.

For tracking, iQuit is free on Google Play and the App Store. You can quit your way, with cold turkey or gradual reduction, log each craving with its trigger and intensity, and see money saved on the dashboard. It is not a medical treatment. If you are weighing options, our comparison of the best quit smoking apps lays out what to look for.
