Tobacco (Nicotiana tabacum L.) is a broad-leafed plant of the nightshade family, indigenous to North and South America, whose dried and cured leaves are often smoked in the form of a cigar or cigarette, or in a smoking pipe, or in a water pipe or a hookah. Tobacco is also chewed, "dipped" (placed between the cheek and gum), and consumed as finely powdered snuff tobacco, which is sniffed into the nose. The word "tobacco" is an Anglicization of the Spanish word "tabaco", whose roots are unclear; it is thought to derive from the Native American word "tabago" a y-shaped pipe used in sniffing tobacco powder.
