Snuff is a smokeless tobacco made from ground or
pulverised tobacco leaves. It is insufflated or "snuffed"
into the nasal cavity, delivering a swift hit of nicotine
and a lasting flavoured scent (especially if flavouring 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.

It originated in the Americas and was in common use in
Europe by the 17th century. Traditional snuff production
consists of a lengthy, multi-step process, in tobacco snuff mills. The selected tobacco leaves are first subject to special tobacco curing or fermentation processes, where they will later provide the individual characteristics and flavour for each type of stuff blend. Snuff is usually scented or flavoured, with many blends of snuff requiring months to years of special storage to reach the required maturity.

Typical traditional flavours are varieties of carefully blended tobacco leaves considered original "fine snuff" without any addition of scents or essences, varieties of spice , piquant, fruit , floral, and mentholated (also called
"medicated" soon followed, either pure or in blends.
Each snuff manufacturer usually has a variety of unique
recipes and blends, as well as special recipes for individual customers. Common flavours also include coffee , chocolate , bordeaux , honey , vanilla, cherry , orange , apricot, plum, camphor , cinnamon, rose and spearmint . Modern flavours include Bourbon , Cola and whisky.

DANGERS IN SUMMARY

It may not be inhaled into the lungs, BUT smokeless tobacco exposes users TO some of the same potent carcinogens as cigarettes. Researchers report that users of smokeless tobacco are exposed to higher amounts of tobacco-specific nitrosamines -- molecules that are known to be carcinogenic -- than smokers...

Note: Carcinogens are cancer causing agents....thus, stuffing exposes you to cancer.

I thought its harmless.

Our grand fathers snuffed and lived to a ripe old age, but these days people don't Snuff but still die young.
