Snuff is a smokeless tobacco made from ground or pulverised tobacco leaves. It is inhaled or "snuffed" into the nasal cavity, delivering a swift hit of nicotine and a lasting flavoured scent (especially if flavoring has been blended with the tobacco).
also it was a song written by slipknot if thats what u ment lol.
Lowering the cost and time needed to conduct trials can promote market competition, help check drug prices, and bring patients innovative medical products earlier.
