Many people think using smokeless tobacco is safer than smoking. But even though there
is no smoke, that doesn't mean it's safe. Smokeless tobacco has very high levels of
nicotine, much more than cigarettes. It is full of harmful chemicals. And it can cause
many kinds of health problems.
What is smokeless tobacco?
Smokeless tobacco is a mixture of:
It is sold in 2 main forms:
Chew. Chew comes in 2 types. The first is the most popular and usually is simply called
chew. This is a leafy form of tobacco. It is often sweetened with molasses or similar
substances. It is sold in pouches. Users keep the chew between their cheek and gums
for several hours at a time. The second type is called a plug. A plug is tobacco leaves
that have been pressed into a brick. Users often bite off or cut a piece of the plug
off and place it between the gum and cheek.
Snuff. Snuff comes in 2 types: moist and nasal (powdered). Moist snuff is often called dip.
It's sold in a circular can called a tin. The tobacco is often flavored. Users place
the tobacco between their lip and gum. This process is known as dipping. Dry snuff
is meant to be breathed in. A user often places the powder on the back of their hand
in a natural space that is called the snuff box. The user then snorts the powder up
their nose. Using snuff also is called dipping.
High levels of nicotine
A person who uses smokeless tobacco gets 3 to 4 times the amount of nicotine as a
smoker. A person who uses 8 to 10 dips or chews a day gets the same amount of nicotine
as a heavy smoker who smokes 30 to 40 cigarettes a day.
Smokeless tobacco is addictive. The addiction is mostly caused by the nicotine. The
nicotine in smokeless tobacco is absorbed by the body more slowly than in smoking.
But it stays in the body longer. And chew tobacco placed inside the mouth gives the
user a constant high from the nicotine.
Many harmful chemicals
The most harmful chemicals in smokeless tobacco are called tobacco-specific nitrosamines
(TSNAs). These chemicals can cause cancer. TSNAs are formed as tobacco is grown, cured,
fermented, and aged. The amount of these chemicals in smokeless tobacco can be very
