Chewing tobacco is a smokeless tobacco product and is one of the oldest ways of consuming tobacco leaves. Modern chewing tobacco is produced in three forms: twist, plug, and scrap. 1  Twist: Leaves are braided and twisted into a rope while green, and then are cured in the same manner as other tobacco. 2  Users cut a piece off the twist and chew it, then expectorate (spit). 3  Modern twist is occasionally lightly sweetened.
