Over the centuries, the terminology used by tobacco growers and the tobacco industry has accumulated into a set of words that make perfect sense to insiders, but can be vague, ambiguous, and even misleading to those not a part of it. While cigars, pipes, pipe tobacco, cigarettes, and smokeless tobacco also have their unique terms (discussed in their sections), only general tobacco terms are covered here. Keep in mind that nearly every variety of Nicotiana tabacum (so-called smoking tobacco) can and probably has been used for nearly every kind of tobacco use or product.
