Tobacco is the agricultural product of the leaves of plants in the genus Nicotiana, commonly termed tobacco plants. All species of Nicotiana contain the addictive drug nicotine—a psychostimulant alkaloid found in all parts of the plants except the seeds, and most heavily-concentrated in the leaves—which occurs in varying amounts depending on the species of Nicotiana grown; the breed, type, or variety of tobacco cultivated and produced; and the method used to cure and process tobacco leaves once they have been harvested.
This article provides a list of tobacco preparations and products. This list includes both tobacco products meant for consumption and those intended for other uses. Under the heading of consumable tobacco products, several categories of tobacco product are described in this list. Of these four basic categories, the first two include what are most often traditional types of tobacco products and preparations, relegated to the broad sub-categories of smoked tobacco and smokeless tobacco; the latter two categories include those types of tobacco products which have only recently been developed or widely adopted: heated tobacco products and nicotine-only products.
A sub-category of nicotine-only products, nicotinized herbal tobacco alternatives, consists of products which include added nicotine but mainly consist of non-tobacco herbal or plant material.
Following is a brief description of each of these categories:
Smoked tobacco products — Tobacco-containing products which consist of tobacco meant for smoking. Common smoked tobacco products include cigarettes, cigars, and hookah tobacco (usually mu'assel).
Smokeless tobacco products — Tobacco-containing products used in a manner which does not produce smoke, while still being distinct from heated tobacco products. Common smokeless tobacco products include dipping tobacco (also called moist snuff or dip), snus, and the various forms of chewing tobacco.
Heated tobacco products — Tobacco-containing products used by heating tobacco in order to produce an aerosol or particulate suspension that can be inhaled.

An electronic cigarette is a handheld battery-powered vaporizer that simulates smoking, but without tobacco combustion. E-cigarette components include a mouthpiece (drip tip), a cartridge (liquid storage area), a heating element/atomizer, a microprocessor, a battery, and some of them have an LED light on the end. An atomizer consists of a small heating element, or coil, that vaporizes e-liquid and a wicking material that draws liquid onto the coil.
Nicotiana tabacum, or cultivated tobacco, is an annually grown herbaceous plant of the genus Nicotiana. N. tabacum is the most commonly grown species in the genus Nicotiana, as the plant's leaves are commercially harvested to be processed into tobacco for human use. The plant is tropical in origin, is commonly grown throughout the world, and is often found in cultivation. It grows to heights between 1 and 2 meters (3' to 6'). Research is ongoing into its ancestry among wild Nicotiana species, but it is believed to be a hybrid of Nicotiana sylvestris, N.
A psychoactive drug, psychopharmaceutical, psychoactive agent, or psychotropic drug is a chemical substance that changes the function of the nervous system and results in alterations of perception, mood, cognition, and behavior. These substances may be used medically, recreationally, for spiritual reasons (for example, by altering one's consciousness, as with entheogens for ritual, spiritual, or shamanic purposes), or for research. Some categories of psychoactive drugs may be prescribed by physicians and other healthcare practitioners because of their therapeutic value.
