Is snuff really safer than smoking?
The FDA says yes, but only in regard to the risk of lung cancer.

Snuff is a smokeless tobacco similar to chewing tobacco. It rarely makes headlines. But it certainly did when the FDA authorized a brand of snuff to market its products as having a major health advantage over cigarettes. Could this be true? Is it safe to use snuff?
What did the FDA authorize as a health claim?
Here's the for Copenhagen Classic Snuff:
If you smoke, consider this: switching completely to this product from cigarettes reduces risk of lung cancer.
While the statement is true, this FDA action — and the marketing that's likely to follow — might suggest snuff is a safe product. It's not. Let's talk about the rest of the story.
What is snuff, anyway?
Snuff is a form of tobacco that's finely ground. There are two types:
Moist snuff. Users place a pinch or a pouch of tobacco behind their upper or lower lips or between their cheek and gum. They must repeatedly spit out or swallow the tobacco juice that accumulates. After a few minutes, they remove or spit out the tobacco as well. This recent FDA action applies to a brand of moist snuff.
Dry snuff. This type is snorted (inhaled through the nose) and is less common in the US.
Both types are available in an array of scents and flavors. Users absorb nicotine and other chemicals into the bloodstream through the lining of the mouth. Blood levels of nicotine are similar between smokers and snuff users. But nicotine stays in the blood for a longer time with snuff users.
Why is snuff popular?
According to CDC statistics, 5.7 million adults in the US regularly use smokeless tobacco products — that's about 2% of the adult population. A similar percentage (1.6%) of high school students use it as well. That's despite restrictions on youth marketing and sales.
What accounts for its popularity?
Snuff may be allowed in places that prohibit smoking.
It tends to cost less than cigarettes: $300 to $1,000 a year versus several thousand dollars a year paid by some smokers.
It doesn't require inhaling smoke into the lungs, or exposing others to secondhand smoke.
Snuff is safer than cigarettes in at least one way — it is less likely to cause lung cancer.
It may help some cigarette smokers quit.
The serious health risks of snuff
While the risk of lung cancer is lower compared with cigarettes, snuff has including
higher risk of cancers of the mouth (such as the tongue, gums, and cheek), esophagus, and pancreas
higher risk of heart disease and stroke
harm to the developing teenage brain
dental problems, such as discoloration of teeth, gum disease, tooth damage, bone loss around the teeth, tooth loosening or loss
higher risk of premature birth and stillbirth among pregnant users.
And because nicotine is addictive, using any tobacco product can quickly become a habit that's hard to break.
