What is pipe tobacco?

Tobacco is an agricultural product processed from the leaves of plants in the genus Nicotinia. It can be consumed, used as an organic pesticide and, in the form of nicotine it is used in some medicines too. In consumption it most frequently appears in the forms of cigarettes, smokeless products like chewing, snuffing, or snus. So, I conclude that people could not exist without tobacco. With tobacco especially with cigarettes, cigars and other smoking products people can relax with their friends after a very hard working day.
