<human>: I want to learn more about the history of snuff.
<bot>: Snuff is a type of smokeless tobacco that was popular in Europe and North America during the 18th century. It was made from ground up tobacco leaves, mixed with spices and finely ground limestone. It was often used as a substitute for chewing tobacco. The term "snuff" comes from the Dutch word "snuffel", which means "to sniff".
