SLT

Smokeless tobacco, usual abbreviated as SLT

Definition.

Smokeless tobacco is a tobacco product that is used by means other than smoking. In other words, this type of tobacco is not burned, its consumption  does not involve  combustion.

The consumption SLT involves chewing, sniffing, or placing the product between gum and the cheek or lip. They are produced in various forms, such as snuff, snus, chewing tobacco and Dissolvables (lozenges, sticks, strips, orbs)

A significant  proportion  of SLT s are considered  safer than combustion  cigarettes  because  they eliminate over 4000 various compounds, most of which are hazardous carcinogens.

SLTs can be a great answer  to the public  healthcare if well integrated in the public  health system.

It is important  to note that because of the ban of such saffer alternatives in some countries gives rise to a "black market" where illicit and unregulated SLTs are sold.

Types of smokeless tobacco

Snus

Snus, a product that originated in Sweden, is moist snuff that comes packaged in small pouches and is often flavored. This product does not produce excess saliva like other forms of smokeless tobacco, making it spit-less.

Separate from American snus, Swedish Snus are produced pursuant to a voluntary standard designed to reduce contaminants and nitrosamine levels (the “Gothiatek” standard). The FDA reviewed some of these 9 Swedish Snus products and permitted their sale in the U.S. and authorized them as modified risk tobacco products.

“Using General Snus instead of cigarettes puts you at a lower risk of mouth cancer, heart disease, lung cancer, stroke, emphysema, and chronic bronchitis.” By allowing them to be sold, FDA concluded that the manufacturer demonstrated that the products will benefit the health of the population as a whole.

Chewing tobacco (“chew”)

Chewing tobacco is available in loose leaves, plugs, or twists of tobacco, and is placed between the cheek and gum or teeth. Examples of chewing tobacco include Red Man and Levi Garrett.

Snuff

Snuff is finely ground tobacco packaged in cans or pouches, which can be sold dry (powdered form that is sniffed) or moist (placed between the lower lip or cheek and gum) and is sometimes used in teabag-like pouches. Popular brands of moist snuff are Copenhagen and Skoal.

Dissolvable tobacco

Dissolvable tobacco is another spit-less, frequently flavored tobacco product that is finely milled and dissolves orally. Ariva and Stonewall are some of the dissolvable products on the market.
