Tobacco is a plant within the genus Nicotiana of the nightshade family. While there are more than 70 species of tobacco, the chief commercial crop is Nicotiana tabacum. The more potent species Nicotiana rustica is also widely used around the world.
Dried tobacco leaves are mainly smoked in cigarettes, cigars, pipe tobacco, flavored shisha tobaccos and are also consumed as snuff, chewing tobacco and dipping tobacco. Tobacco is also sometimes added to cannabis by smokers for various reasons, from making joints or bongs burn better to making their cannabis last longer.

- Early onset of tobacco use may act as a "gateway" to future marijuana use.
