There are many species of tobacco, which are all encompassed by the plant genus Nicotiana. Tobacco is cultivated similarly to other agricultural products. Seeds are sown in cold frames or hotbeds to prevent attacks from insects, and then transplanted into the fields. Tobacco is an annual crop, which is usually harvested in a large single-piece farm equipment. After harvest, tobacco is stored to allow for curing, which allow for the slow oxidation and degradation of carotenoids. This allows for the agricultural product to take on properties that are usually attributed to the "smoothness" of the smoke. Following this, tobacco is packed into its various forms of consumption which include smoking, chewing, sniffing, and so on. (Wikipedia)
