TOBACCO PRODUCTS
Tobacco is the agricultural product of the leaves of plants in the genus Nicotiana. All species of Nicotiana contain the addictive 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. See types of tobacco and curing of tobacco for more information.

The vast majority of commercially available tobacco is derived from the species Nicotiana tabacum, although it is also produced from Nicotiana alata, and to a lesser extent Nicotiana clevelandii, Nicotiana longiflora, and Nicotiana rustica, among others. N. rustica in particular contains much more nicotine than N. tabacum and other species of Nicotiana, and forms the basis of a number of unique tobacco products, including several preparations used in Latin American shamanic ceremonies.

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 (see tobacco smoking) 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.

The health effects of tobacco consumption are discussed in the article health effects of tobacco.

Cigars

A cigar is a tightly rolled bundle of dried and fermented tobacco which is ignited so that its smoke may be drawn into the smoker's mouth and expelled; thus the cigar is generally "puffed on" (like a tobacco pipe) as opposed to being inhaled from (as is the case with cigarettes). The cigar is one of the oldest methods of preparing tobacco for consumption, some of the first cigars being introduced to Europeans as rolls of tobacco smoked by the Taíno of 15th century Cuba.

There are numerous varieties of cigar, differentiated by their respective size, shape, color, and composition. Some products developed from the cigar are, however, markedly different from the traditional product. (Cigarillos, blunts, and little cigars, for instance.) Cigarettes may be the most notable example of this deviation, although they do, in a sense, represent a category of their own.

Tobacciana associated with cigars include cigar tubes, cigar boxes, cigar holders (also known as "cigar mouthpieces"; cf. cigarette holder), cigar cutters (including cigar scissors or shears), cigar cases, and humidors.

Blunts

Blunts are wide, somewhat stubby versions of cigars. Most, if not all, are machine-made "domestic cigars" created from homogenized or reconstituted tobacco. They are usually inexpensive, and only lightly fermented.
