The Dutch, who named the ground powdered tobacco "snuff" ("snuif"), were using the product by 1560. By the early 1600s, snuff had become an expensive luxury commodity. In 1611, commercially manufactured snuff made its way to North America by way of John Rolfe, the husband of Pocahontas, who introduced a sweeter Spanish variety of tobacco to North America. Though most of the colonists in America never fully accepted the English style of snuff use, American aristocrats used snuff. Snuff use in England increased in popularity after the Great Plague of London (1665–1666) as people believed snuff had valuable medicinal properties, which added a powerful impetus to its consumption. By 1650, snuff use had spread from France to England, Scotland, and Ireland, and throughout Europe, as well as Japan, China, and Africa.
