Smokeless tobacco is a tobacco product that is used by means other than smoking. Their use involves chewing, sniffing, or placing the product between gum and the cheek or lip. Smokeless tobacco products are produced in various forms, such as chewing tobacco, snuff, snus, and dissolvable tobacco products.

Snuff is a smokeless tobacco made from finely ground or pulverized tobacco leaves. It is snorted or “sniffed” (alternatively sometimes written as “snuffed”) into the nasal cavity, delivering a swift hit of nicotine and a lasting flavored scent (especially if flavoring has been blended with the tobacco). Traditionally, it is sniffed or inhaled lightly after a pinch of snuff is either placed onto the back surface of the hand held, pinched between thumb and index finger, or held by a specially made “snuffing” device.
