Tobacco is the agricultural product of the leaves of plants in the genus Nicotiana. All species of Nicotiana contain the recreational drug nicotine—a stimulant and sedative contained in all parts of the plants except the seeds—which occurs in varying amounts depending on the species and variety cultivated. It is thought that an interaction between nicotine and MAOI beta-carbolines found in tobacco account for the addictive properties of its use.
Tobacco is primarily derived from the species Nicotiana tabacum, although it is also produced from Nicotiana alata, and to a lesser extent Nicotiana clevelandii, Nicotiana longiflora, Nicotiana rustica, and others.
Once tobacco has been grown, harvested, cured, and processed, it is used to produce a number of different products. These are most often consumable; however, tobacco and the nicotine derived from it are also used to create pesticides.
Tobacco products can generally be divided into two types: smoked tobacco and smokeless tobacco.
An expert in tobacco and tobacco products—especially pipes, pipe tobacco and cigars—including their procurement and sale, is called a tobacconist.
Famous quotes containing the words tobacco and/or products:
“The puritanical potentialities of science have never been forecast. If it evolves a body of organized rites, and is established as a religion, hierarchically organized, things more than anything else will be done in the name of “decency.” The coarse fumes of tobacco and liquors, the consequent tainting of the breath and staining of white fingers and teeth, which is so offensive to many women, will be the first things attended to.”
—Wyndham Lewis (1882–1957)
“The measure discriminates definitely against products which make up what has been universally considered a program of safe farming. The bill upholds as ideals of American farming the men who grow cotton, corn, rice, swine, tobacco, or wheat and nothing else. These are to be given special favors at the expense of the farmer who has toiled for years to build up a constructive farming enterprise to include a variety of crops and livestock.”
—Calvin Coolidge (1872–1933)
