Cultivation of tobacco in the context of "Tobacco products"

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 metres (3.3 and 6.6 ft). Research is ongoing into its ancestry among wild Nicotiana species, but it is believed to be a hybrid of Nicotiana sylvestris, N. tomentosiformis, and possibly N. otophora.

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.
